Using .Net from VB6 ActiveX control

Mon, 16 Mar 2009 12:00:27 Z

Folks,

The scenario I am working currently is as follows:

I have an ActiveX Control written with VB6 named ABC.OCX, and I want to use a .net class to carry out some tasks that the activeX control needs. So I have written a .net Assembly named MyDotNetAssembly that contains the class MyDotNetClass with it's interface IMyClassInterface. after than, I have checked the build option "Register for COM interop" and used this assembly as a reference assembly form my ActiveX vb project. Than I have created the internet-style CAB file using the "Setup and deployment wizard" of VB6, and the generated output directory contains a sample HTML file that hosts the ActiveX and when I run this HTML form browser it works!!.

I have then used the ActiveX control inside my ASP.net application's page (using the regular object tag inside html) and it works fine onto the development box.

So far so good.

Now, as soon as I try to access that page from outside of Development box, it doesn't render the activeX control at all. No error.....nothing!!! During the first hit, it asked me to install the active X, and I have installed that nice. I have made the web site as a trusted site in my VISTA machine. but it doesn't render anything for that activeX neither shows any errors..?

Can anyone guess anything..? I would greatly appreciate any helps.

does MSI allow installation of x86 interops in the GAC if the GAC already has the same interops have a higher versioned x64 already installed?

Sat, 14 Mar 2009 22:20:00 Z

Hi,

I have found that if there are x64 interops of a particular version installed in the GAC, then MSI does not allow x86 interops (the same interops as the already installed x64) of a lower version to be installed into the GAC. It seems like if the x64 interops are installed beforehand, MSI technology does not take into account that they are x64 while trying to install x86 versions of the interops and instead simply looks at the versions and if they installed interops have higher version, irrespective of the fact that they are of a different architecture (x64 in this case), the x86 interops are not able to be installed.

Interesting if the x86 interops are installed beforehand, that has no bearing on the MSI trying to install x64 versions of those interops irrespective of the actual file version of the interops.

So, looks like when trying to install x86 interops, MSI technology does not take cognizance of the assembly architecture if there are x64 versions already installed, and instead just looks at the file version. I did run some tests by bumping the version numbers of the interops in question and turns out the above analysis is true.

Is this correct. Looking for some confirmation.

Thanks,

Windows 2000 SP4 Domain Controllers

Tue, 10 Mar 2009 12:33:15 Z

I have two Windows 2000 SP4 Server DCs that are hosted on a VMWare box that are only 4GB partitions and therefore can't do an in-place upgrade to Windows 2003 due to disk space limitation etc. I do have another server I can use..meaning I can build that server fresh with windows 2003 and make it a 2003 DC for this same domain and de-commission one of the other 2000 DCs etc. Then free up another server to remove the other 2000 DC. Can I operate with mixed DCs at 2000 and 2003 OS? What do you recommend for the best process to do this? What do I need to be aware of and what pre-reqs should I do prior to starting? Do I need to move any DC roles over to the 2003 server etc? Thanks much for your help. I just want to make sure I have my ducks in a row prior to starting.
Also, my exchange server is already running windows 2003 std sp2 and exchange 2003 sp2 so I assume I am good to proceed without any changes there etc.

Question AcriveX Outlook component problem while using with LabVIEW 8.6

Tue, 10 Mar 2009 09:33:20 Z

Gagandeep_Singh - Posted 27 minutes ago

Hi,

I am using LabView 8.6 version. I am facing an issue with outlook component that i am using in the code.
The description for the same is as follows.

I use ActiveX component for outlook to send automated mails repeatedly from our LabView application. While running the application for a long time I got the following exception from the outlook component:

Error:-2147221223 :Exception occurred in Microsoft Office Outlook: Cannot create the e-mail message because a data file to send and receive messages cannot be found. To add a data file, such as a personal folder file, double-click the Mail icon in Windows Control Panel. in EmailCommunicationHandler.vi->DataAcquisition.vi

The sending of emails worked fine for first few emails and then I consistently got this error.
The outlook application was configured properly and we had proper data files and accounts configured for sending and receiving the emails.

Can you kindly let me know what is the root cause of this exception and how to resolve this issue.

Regards
Gagandeep Singh

Internet ExplorerClass Visible property not working when InternetExplorerClass is instantiated in a web service

Wed, 17 Dec 2008 11:07:29 Z

Hello,
I'm trying to open a new Internet Explorer window each time a web method of a certain web service is called.
The window seems to be created as I can see the process iexplore.exe in the task manager, but is always invisible even if I set Visible property of InternetExplorerClass instance to true.
Below is the code I am using:

 [WebMethod] 
    public string OpenIE() { 
        ThreadStart ts = delegate 
                             { 
                                 InternetExplorer ie = new InternetExplorerClass(); 
                                 ie.Visible = true; 
                                  
                             }; 
        Thread t = new Thread(ts); 
        t.SetApartmentState(ApartmentState.STA); 
        t.Start(); 
        t.Join(); 
        return string.Empty; 
    } 

The above code executes successfully and produces no exceptions.
Does anyone know what the problem could be?
Thanks

getting upgrades on XP2 via Parallels

Thu, 05 Feb 2009 15:52:42 Z

Hello. I am using Windows XP SP2 on a Mac OSX, via a Parallels program. When I try to download an upgrade to Internet Explorer 7 in order to upgrade to SP3, I get a message "We were unable to install. . . ." I've tried making exceptions to the firewall, even canceling the firewall, but nothing works. Meanwhile, I can't get any updates whatsoever. I'd be grateful for any guidance. Apologies if I'm in the wrong subject category.

General Discussion I am trying to retrieve a selected value from a listbox and store it in a string variable using Win API

Fri, 23 Jan 2009 12:00:54 Z

I am trying to retrieve a selected value from a listbox and store it in
a string variable.
I am using the following code:
            int count = 0;
            List<string> retVal = new List<string>();
            string item;
            IntPtr zero = new IntPtr(0);

            //Get the count of items in the list
            IntPtr ptr = SendMessage(listBox1.Handle, LB_GETCOUNT, zero, zero);

            count = ptr.ToInt32();

            StringBuilder sbText = new StringBuilder(256 + 1);
            SendMessage(listBox1.Handle, LB_GETTEXT, (count - 1), sbText);
            string str = sbText.ToString();

            MessageBox.Show("Text:" + str.Trim());
    This does not work and when I look at the value of Text it is
    "[09]" and not as I expected.

im passing the listbox handle to VC dll, which in turn will post back message to listbox.the problem is "listbox.count" shows me zero.so im using WIN API to retrieve the text from listbox. using LB_GETCOUNT im able to get the counts correctly but using LB_GETTEXT it gives me some junk value.

Problem installing Office Home 2007

Sat, 17 Jan 2009 14:05:09 Z

My son just bought MS Office Home and Student 2007 and went to install it and was having problems, so he brought his PC and the box to me. Figured Dad could figure it out. Well I'm on here, so guess what - I couldn't.

It comes up that it can find the following message "Setup cannot find HomeStudentr.WW\HomeSrWW.cab.
Browse to valid installation source, then click OK". Well the file is on the CD, so I pointed to the directory and it still comes up and says it can't locate. I then copied that whole directory to the C: drive and tried that. Still gives me the same issue.

Any ideas?

Thanks,

Dave

Params array does not work with COM Interop

Mon, 05 Jan 2009 22:17:51 Z

Hello everybody,

My main problem is that I cannot get methods with params array parameters working when they are called from a scripting language such as JavaScript.

Details: I'm stuck with a JavaScript/C# interop problem when using the WebBrowser control. I assign a C# object to the Webbrowser.ObjectForScripting property. Now, any JavaScript can access this object through 'window.external' and call methods and read/write properties. The class definition for this object is attributed with ComVisible.

This all works fine for methods with a fixed amount of parameters. However, I have to provide methods that accept an unlimited number of parameters. In C# this is done with the 'params object[]' construct. However, COM doesn't like this. From what I found out so far I think that this cannot be accomplished using an early-bound COM interface. Rather, when looking from a pure COM persepctive my object needs to implement the IDispatch interface. Then the IDispatch.Invoke method accepts any number of parameters.

I have searched the Internet for quite a while but could not find much relevant information. There are bits and pieces such as the DispId attribute but I don't see how this could fit my particular problem.

Hare a couple of questions that are floating around and whose answers might help soving the issue at hand...
-How does VB6 achieve variable number of parameters, especially when no late-binding is used?
-If I have to implement a C# method that accepts an array of variants (or so), will the scripting client still be able to use a syntax like 'object.method(var1, var2, var3,...)
-Is it possible or required to implement IDispatch manually in C#? Or can some of the Interop attributes be used to achieve the 'params' effect for the scripting client?

Phew, so many questions, so few answers ;-) Thanks a lot for your sharing thoughts,

Christoph

Cannot access my external drives

Fri, 09 Jan 2009 17:24:31 Z

I am using Windows XP and use external hard drives to back up my information. It was working fine until recently when my PC stopped recognizing that there was a drive attached at all. Does anyone know how to fix this? I have connected and reconnected the external drives and also tried different USB ports.

Have I posted this to the correct forum. Someone please let me know where I can find an answer to this.

Problem in calling 32 bit COM component from C# .NET on 64 bit windows server 2008 machine - events not firing

Fri, 09 Jan 2009 16:26:46 Z

Hi
I have C# .NET code that calls a third party 32 bit COM component. This COM component will fire events that I need to subscribe to and handle.
My server runs windows server 2008 while my development machine runs windows xp(64 bit).

I have installed the COM component and its 2 dependencies in the syswow64 folder on both machines. Then I add a reference to the COM dll using the add references wizard - COM tab. This generates the interop dll for the third party component.

While this works fine on my development machine - events are fired which I can handle in my .NET code, it does not work on the server.
No errors are thrown on the server. I can instantiate an object of the third party component . I can even set its properties and read them back. However no events are thrown from it.

I have tried hooking up events using the standard += method and also tried using the IConnectionPointContainer method (event handling without delegates). Both do not work on the server and both work on my machine. It also runs on other machines that I have tried.

I am running them as admin on both machines.
The third party provider is not able to recreate this error either - been trying for 3 weeks now.

Problem with processing .hcc files to display help contents using Windows XP Professional

Mon, 22 Dec 2008 02:46:34 Z

Hi,

I encountered a problem when trying to process the contents a .hcc file to display help contents. Instead of displaying the contents, it displayed a blank window.

The code I used to generate it is as follows:

<object id="hhctrl" codebase="../../sam/hhctrl.ocx#Version=4,74,8793,0" type="application/x-oleobject" height="87%" width="100%" classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<param NAME="Width" VALUE="13123">
<param NAME="Height" VALUE="6500">
<param NAME="Command" VALUE="Contents">
<param NAME="Item1" VALUE="../common/all.hhc">
</object>

It could be due to the service 2 upgrade on windows. If it is really a compatibility problem, are there any other alternatives to implement it?

Thanks.

C#.NET + Java script error in Screen Scrapping application

Thu, 18 Dec 2008 07:57:02 Z

We are facing some issues in our current application. The details about the problem are given in comments.

Comment : We are doing screen scrapping application using C#.NET Win forms and web browser control. We need to automate “search” functionality in one of the web application hosted in the web browser control. We have 2 pages viz. “Search” page and “DetailsResult” page. The details about the issue is given in steps.

Step 1: when the application is launched “Search” page is loaded in to web browser control

Step 2: we programmatically provide data to be searched in text fields and click on the search button on the “Search” page

Step 3: Then, search results are displayed on “Grid” control on the same page

Step 4: The details about the search result is shown in “Details” Page. This page is called as soon as we click on the hyperlink present in the data grid.

For the first iteration, i.e. from step 1 to step 4, works fine.

However the problem starts for second iteration. When we try to search new records as per the step 2 we get an java script error “Connection undefined”. And hence code is not able to perform step 3 and step 4.

Can anyone provide pointers about the above issue?

Thanks & Regards,

Question about MS DHCP server

Wed, 17 Dec 2008 11:36:02 Z

Sorry, this is cross-post from "Using the Open Specifications", but I'm not sure that I've used right place

But anyway...
There is a problem with how MS DHCP server handles option 55 specified by client in offer/request packets. One of my dhcp clients sends discover/offer with a number of required options in value of option 55 (see http://www.faqs.org/rfcs/rfc1533.html, 9.6. Parameter Request List). DHCP server responds with exactly requested option but without some witch were not requested. That client actually wanted to receive some more together with requested ones (and rfc say that option 55 do not set limit on what should be returned but specify order of option which should be used in response). So I'm looking for any way to override that behavour and make dhcp server respond with some more options together with specified ones, actually a way to override that list specified by client. So if there are any ideas on how to achive that, please give a clue...

Excel interop - 80080005 error

Thu, 11 Dec 2008 11:16:56 Z

I work with excel 2003 interop in my asp.net web service. It basically converts the excel to xml so that I can parse the excel spreadsheet.
Since there is a problem of excel interop cleanup, i create a pool of excel objects and keep them in memory.
The problem is, intermittently i get the error:
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80080005.
This does not happen for all requests. It happens randomly. Sometimes after few instatiations it throws up this error for every new excel object i request.
What could be the reason?
I have given launch and activation permissions to aspnet account on excel in dcomcnfg.
The trouble is this is happening "randomly".
I don't use impersonation.

if included afxwinforms.h; createinstance for component present in same dll fails.

Thu, 11 Dec 2008 08:07:49 Z

Hi,

I have one dll containing 3 MFC com component and some 2-3 MFC dailog. I want to load one Managed (C#) control in one of the dialog. I have added managed control in MFC dialog, compiler option for file set to /clr. dll created without any error.

But when I call CreateInstance for any of the MFC component, it fails saying "0x80040111 ClassFactory cannot supply requested class ". It works fine if i remove managed control from dialog.

Further, I investigated and found that whether I add managed control or not it does not have any effect. Only when i include in any file and compile using /clr option; CreateInstance falis with above error. if i remove and keep /clr option then it works fine.

Thanks

Excel interop

Thu, 11 Dec 2008 07:46:33 Z

I have an application that is exporting some data in an excel file. The problem is when the export is ran on a machine that doesn't have Excel 2003 installed. When I try to export on a machine that has office Xp installed i have the error below, even if i test the version of excel installed. I don't understand why it tries to find the office dll, even if I don't try to export. And the error happens only if I press the export button, it doesn't happen on other buttons on the form. And it seems that it doesn't even reach the IsOffice2003 method, because i put a message to be displayed before the call to the method and the message didn't appear.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

FAXCOMLib

Wed, 10 Dec 2008 16:27:39 Z

Hi,

I am using FaxCom Lib in our application. actually i am sending images which are in the form of TIFF formate, By the following like code..

FAXCOMLib.FaxDoc fd;

FAXCOMLib.FaxServer fs = new FAXCOMLib.FaxServerClass();

fs.Connect(".");

fd = (FAXCOMLib.FaxDoc)fs.CreateDocument(@"C:\test.tif");

fd.FaxNumber = "89898";

fd.RecipientName = "tsagdhbwas"; ;

fd.SenderName = "askhdkjja";

fd.Send();

it was working will with, some tiff files but not with all, for most of the Images it is giving error like ..

{"The object identifier does not represent a valid object. (Exception from HRESULT: 0x800710D8)"}

{System.Collections.ListDictionaryInternal}

error code = -2147020584

source = "Interop.FAXCOMLib"

stack trace = " at FAXCOMLib.IFaxDoc.Send()\r\n at ConsoleApplication1.Program.Main(String[] args) in C:\\MOI Fax Agent\\ConsoleApplication1\\ConsoleApplication1\\Program.cs:line 63\r\n at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args)\r\n at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args)\r\n at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly()\r\n at System.Threading.ThreadHelper.ThreadStart_Context(Object state)\r\n at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)\r\n at System.Threading.ThreadHelper.ThreadStart()"

as my observation, FAXCOMLIB will do process with printer like driver, and capture print image from the file what we specified with in the code, but all images what ihave are working with if i do print with fax drives which are coming up when i install Fax console.

Thanks and Regards

Modifying documents

Fri, 05 Dec 2008 17:22:39 Z

I'm using a third party to export the report document to HTML, TIFF, PDF, TIFF, TXT and XLS format. But I'm having a problem because my document has a link/url on it and everytime I exported it the link/url was also carried. I'm able to resolve the XLS document by using the code below.

Dim Excel_file As New Microsoft.Office.Interop.Excel.Application
Excel_file.Workbooks.Open(strPath & "\" & strFileName & ".xls")
Excel_file.Visible = True
Excel_file.Worksheets.Application.Columns.Hyperlinks.Delete() 'This will delete the link/url

Does anyone know how can I apply this to other document?
Your suggestion is highly appreciated.

Thanks in advanced..

Bitlocker

Wed, 26 Nov 2008 15:13:36 Z

If I were to use Bitlocker on a 2008 web and database server, would I be able to connect as ususal from an XP workstation. (My thought was yes, of course.) And will bitlocker slow down the DB & web service running on the server. The server is TPM compliant and attached to the same AD as the XP workstation.

Excel 2003 macros with VB2008

Tue, 18 Nov 2008 15:36:24 Z

Trying to write a program in VB08 that uses Excel 2003 as an interface. To help with this I am calling macros inside the Excel sheet from VB. The problem is that even when I pass parameters byref to the macros, they always come back byvalue, ie unchanged. So for example when I do:

Call gXLApp.Run(gwbTB.Name & "!ArrGather", gArr) 

where I am passing array gArr for the macro to populate, it comes back still empty. Any ideas why this is happens or how to get around it?

Explorer is running, yet nothing shows up (XP)

Sat, 15 Nov 2008 00:03:44 Z

I logged in, and the screen was blank, this happens occasionally, and all that was showing was my desktop background. The only way I can navigate on windows is if I use task manager. I opened task manager, and explorer was running, so I ended it and ran in again, and everything came back, the taskbar, desktop, etc. but my startup programs such as Avira, Gadwin, and all the other programs in my startup folder didn't start. Is there a process I can run that will, pretty much, refresh my Windows session without having to logout and log back in? I am running a Windows XP Home Edition (version 2002) with Service pack 3.

Getting events from a COM object

Wed, 12 Nov 2008 10:33:18 Z

Hello:

I don´t know if this question belongs or not to this thread, but if you consider that there´s a suitable thread for it, please, let me know.

About my question: I´m trying to get the events of a COM event source object and a part of this task is implementing the dispinterface handling those events through inheriting the ATL class IDispEventImpl. Later on my code I call to DispEventAdvise in order to connect the outgoing interface of the connectable object (the event source object) with the proper connection point. Everything compiles fine and such a call succeeds, however, the application exits each time it gets an event, so that makes me think that I did something wrong in relation with the event handling mechanism.

Here there is the sink object implementation:

static _ATL_FUNC_INFO _funcOnText = {
CC_STDCALL,             // Calling convention.
VT_I4,                         // Return type.
1,                           // Number of arguments.
{                                  // Argument types.
    VT_BSTR
}
};

class SrmPseudoDocumentEvents : public IDispEventImpl<1,
       SrmPseudoDocumentEvents,
       &__uuidof(SmIa::PseudoDocumentEvents),
       &GUID_NULL, 1, 0>
{

public:

SrmPseudoDocumentEvents() {

};

virtual ~SrmPseudoDocumentEvents() {

};

STDMETHODIMP OnText(BSTR a_recognizedText) {
    KlDebugAlways("Text event !!!");
    return S_OK;
};

BEGIN_SINK_MAP(SrmPseudoDocumentEvents)
    SINK_ENTRY_INFO(1, __uuidof(SmIa::PseudoDocumentEvents), 0x01, OnText, &_funcOnText)
END_SINK_MAP()

};

And here I call the DispEventAdvise method call:

SrmPseudoDocumentEvents pseudoDocumentEvents = SrmPseudoDocumentEvents();

hr = pseudoDocumentEvents.DispEventAdvise(reinterpret_cast<IUnknown*>(m_pIPseudoDocument),
                                            &__uuidof(SmIa::PseudoDocumentEvents));
if (FAILED(hr)) {
    return getHResultInfo(hr,
                          reinterpret_cast<IDispatch*>(&pseudoDocumentEvents),
                          __uuidof(SmIa::PseudoDocumentEvents));
}

Thank you beforehand,

MS WORD 2003 ISSUE WITH 2007 CONVERSION UTILITY AND\OR SP3

Fri, 24 Oct 2008 17:45:25 Z

I believe I have found an issue with MS Office Service packs. What I have been trying to do is to open a MS word 2007 file (that has an embedded XML table) with MS Word 2003 (with Office SP3) and it will not open.

Here is the hitch, If I have MS Word 2003 and I install the Word 2007 conversion utility, the file will open, but that is only if I havent installed the Office SP3.

If I have the baseline version of Office 2003, it will not open unless I install the conversion utlity, but for any PC that I have SP3 installed, it will not open the file.

I am looking for a workaround, so that all of the PC's that have Office 2003 WITH SP3 installed, will open the Word 2007 document.

I am not sure if the embedded XML table is causing this problem, or not.

Thank you

Outlook object in Javascript

Wed, 22 Oct 2008 18:21:12 Z

Hello,
I am using javascript to create an outlook object and trying to read a public folder item. I am able to do so with outlook itself, but when I use javascript its giving me an error.
Error Number: -2147024891, Error Message: You do not have sufficient permission to perform this operation on this object. See the folder contact or your system administrator.
I am also able to access the mails through webmail.
Any reason why this is happening?
Following is the code:
var oOutlook;
var pub;
var item;
var safeobject;
try
{
    safeobject=new ActiveXObject("SafeBrowserScripting.ObjectGenerator");
}catch(e)
{
    oOutlook = new ActiveXObject("Outlook.Application.");
}
if(safeobject==null)
{
    oOutlook = new ActiveXObject("Outlook.Application.");
}
else
{
    oOutlook=safeobject.GetSafeObject("Outlook.Application");
}
var folderId="18";
pub = oOutlook.Session.GetDefaultFolder(folderId);
item = oOutlook.Session.GetItemFromID(entryID, pub.StoreID);
item.Display();
}catch(e)
{
    if ( e.number != 0 )
    {
        if ( e.number == "-2146823281" )
        {
            alert("You do not have sufficient privileges to read the email.");
        }
        else
        {
            alert("There was an error opening the Research email.");
        }
        window.status = "";
        return;
    }
}
This is not happening with all users, its happening only with few users. I have been trying to fix this over 3 weeks now.

Accessing VB6 COM DLLs with VB.NET

Fri, 17 Oct 2008 08:43:09 Z

Using Visual Studio 2005 I am trying to reference a VB6 written COM DLL, which is used in current VB6 projects. The process I use is to select 'Add Reference' from the Project menu. I then find the DLL I require under the COM tab when I select it to add it however Visual Studio crashes with the 'Microsoft Visual Studio has encountered a problem and needs to close.' / Send Error Report message.

Could it be something within the DLL that is causing Visual Studio problems or is there something else I need to do within visual studio for it to use a VB6 written COM DLL.

Thanks in advance

Questions on Usage of a .NET Component from VB6 and VBScript

Thu, 16 Oct 2008 12:52:16 Z

Hi All,

We are dealing with .NET server component and COM clients written with VB6 and VBScript. And there are some problems we faced (please see code below).

1. Managed type System Drawing.Color is automatically marshaled to VB type OLE_COLOR only in case of early binding. (see DealWithColor() method).

2. For class Component public variable DateTime dt can be used in both early and late binding cases, whereas public variable Color clr causes failure in late binding and works fine in early binding.

3. Method public void Info(MyPointClass pt) works fine with VB6 for both early and late binding but fails in VBScript.

[ComVisible(true)]

public struct MYPOINT

{

// These are now private!

private int xPos;

private int yPos;

[MarshalAs(UnmanagedType.BStr)]

private string name;

// Add some members to the MYPOINT struct.

public void SetPoint(int x, int y) { xPos = x; yPos = y; }

public void DisplayPoint() { MessageBox.Show(string.Format("X: {0} Y: {1}", xPos, yPos), name); }

}

[ComVisible(true)]

[ClassInterface(ClassInterfaceType.AutoDual)]

public class MyPointClass

{

private int xPos;

private int yPos;

private string name;

public void SetPoint(string name, int x, int y) { this.name = name; xPos = x; yPos = y; }

public void DisplayPoint() { MessageBox.Show(string.Format("X: {0} Y: {1}", xPos, yPos), name); }

}

[ComVisible(true)]

[ClassInterface(ClassInterfaceType.AutoDual)]

public class Component

{

// Success in Early Binding. Failure in Late Binding (Both VB6 and VBScript)

public Color clr;

// Success in Early Binding and Late Binding (Both VB6 and VBScript)

public DateTime dt;

// Success in Early Binding. Failure in Late Binding (Both VB6 and VBScript)

public Color DealWithColor(Color col)

{

MessageBox.Show(col.ToString(), "DealWithColor() Method");

return col;

}

// Success in Early Binding. TODO Late

public void Info(ref MYPOINT pt)

{

pt.DisplayPoint();

}

// Success in Early Binding and Late Binding (Both VB6 and VBScript)

public void Info (object pt)

{

(pt as MyPointClass).DisplayPoint();

}

// Success in Early Binding and in Late Binding VB6. Failure in VBScript.

public void Info (MyPointClass pt)

{

pt.DisplayPoint();

}

'Late Binding via VB6

Dim ptc As CallNetFromVB6.MyPointClass

Detecting UDP packet loss when connecting video-streamers to a Windows-2003-Server hosted application

Thu, 09 Oct 2008 19:14:02 Z

Hello,

I hope this is the right forum (I found no forum on MSDN that really matches).

We're connecting several hundred hardware video camera devices to a Windows 2003 Server system. The hardware devices speak the RTP protocol using UDP multicast. I'm currently writing the receiving application that has to handle several 100 mbit/s of incoming video data.

I'm using .NET sockets (that perform quite fast as we measured, maybe because MS did a good by using IOCP etc. :). When I use a very small UDP-Socket-Buffer size I see lots of packet losses. When I use a big UDP-Socket-Buffer I see no packet losses. So the small UDP-Socket-Version that looses packets should loose the packets in the UCP-Socket-Buffer and nowhere else, right ? So I can use the small UDP-Socket-Version as a test-tool to enforce packet-loss in the UDP-Buffer.

When I use "netstat -s" I don't see any of the packet loss I enforced with the small-UDP-buffer-application. It is important for us to have a tool handy for our customers (airports, banks, subways ...) to analyze in case of trouble if there's an overflow in the sockets UDP-buffer or if anything else drops too much packets (Camera, Switch, NIC, Server-Application whatever ...).

I tried not only "netstat -s", I also tried almost any good-sounding perfmon counter ... but I didn't see the packet loss I enforced.

Question:
How can I see wether there's packet loss in the UDP-socket-buffer ? Is "netstat -s" the right command ? Is it reliable ? Does it depend on features of the NIC-driver ? Why don't I see the dropped packets created with my test-tool ?

Thanks a lot,
Roelof Berg
