VB6 ActiveX Control doesn't work while using .NET from the ActiveX control.

Mon, 16 Mar 2009 12:03:48 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.

Crystal Reports 2008 using .NET 3.5 issue

Tue, 27 Jan 2009 15:01:30 Z

Hello,

I have ceated my custom Crystal reports using a composite control where I create dynamically my ReportViewer and ReportDocument and feed it with data.

Before upgrading to .NET 3.5 everything worked fine.

When I upgraded to VS 2008 / .NET 3.5 the reports load the first time correctly, but when I click on one of the node in the left tree ( Grouping by date for example) I should wait like 20 seconds to get the response.

I don't know the cause of this delay. I debugged the code and found that After I load the report to the Viewer in the page Load event, it takes like 20 seconds to jump to the Unload event of the page.

This only happens when I click one of these nodes in the tree.

Any suggestions?

Manually adding Find Results entries

Mon, 26 Jan 2009 23:10:23 Z

For a product based on the VS shell, I'm planning to implement my own find/replace functionality rather than relying on the VS framework. But if possible I would like to use the Find Results pane which the shell already provides.

Three years ago this question was asked and someone stated that this functionality might be added in later VSX editions.

http://social.microsoft.com/Forums/en-US/vsx/thread/01035412-26f1-4f71-8de1-9016de4e2ecb

Is this functionality available in the 2008 VS SDK? I haven't seen any related documentation, so I'm suspecting not...

Thanks,

Nathan

Remote registry problem

Mon, 26 Jan 2009 22:46:13 Z

Greetings!

I have a small problem, or should say big, because if've been googlin it for past 6hours.

I want to use one software GFI Languard which scans the entire network of the computers in a domain to see the list of software that we have in company, but I have problems to connect to several computers.

I'm using a domain administrator password and some computers are able to show me the results, but others don't. The error that appears is, that they have problem connecting to the REMOTE REGISTRY, but what is strange, that all of them have this service (remote registery) started automatic.

Uncle Google said, that users must have in registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SecurePipeServers\Winreg set permissions right -> Administrators full control, and Local service read control.

I have checked it, and the computer that shows me the result has the same settings as the computer that saids he can't connect to remote registry.

Also I found out if log on to the computer that doesn't want to connect to remote registry, and if I go under CONTROL PANEL --> user accounts, and ADD there a domain administrator DOMAIN\Administor to be a local administrator, suddenly it shows me the results with GFI Languard. But I would need a different solutions, because I can't log in on every computer (we have more then 200 computers) and add this domain administrator to be local administrator. I thought that domain administrator is "a king" and that he is able to do anything on all the computers in the same domain. Soo please help me, how to solve and determine why some computers allow to connect to remote registry and others don't, but they have both this service on.

Thank u

stsadm createssp Provisioning Failed

Sat, 24 Jan 2009 02:10:48 Z

provisioning failed: user does not have permission to perform this action

We are on the last step of the Deploy using DBA created databases document in an environment where we do not have dbcreator or securityadmin on the SQL server. We encounter the message above after about 10 minutes of waiting for the createssp command to complete at the command prompt.
Environment is Win Server 2003 x64 SP 2 (In a 2 server deployment w/ Central admin installed on both servers, 1 as Index, and 1 as Query)
w/SQL 2005 x64 SP 2
MOSS 2007 w/ SP1 (latest MSDN combined version)
.Net 3.5

The result is that the SSP admin interfacece is created, but there is a red x on the central admin screen next to the shared service provider name along with the error message above (the MySites, SSP App, and Portal site are all listed under it). In addition when accessing Search Settings, the following error is displayed: The seach application is not provisioned because a Shared Service Provider has not been created.

We followed the document to the T, and have provided access to the appropriate accounts to the databases as instructed.

When running a SQL trace, we noticed the same error message happens on the following command:
exec sp_executesql N'declare @user_name sysname select @user_name = SUSER_SNAME(@sid) if (@user_name is not null) exec sp_grantlogin @user_name declare @db_user_name sysname select @db_user_name = name from sysusers where sid = @sid if (@db_user_name is null and @user_name is not null) exec sp_grantdbaccess @user_name, @db_user_name output if not user_id(@db_user_name) in (1,0,3,4) exec sp_addrolemember @role, @db_user_name',N'@sid varbinary(28),@role nvarchar

It was executed against the config database by the install account. sp_grantlogin is the problem here and this runs even though the account has already been added to the database.

This could be a new bug introduced in the MOSS 2007 SP1 installer when using DBA created databases with minimal permissions.

VS2005 Remote Debugger fails

Wed, 21 Jan 2009 20:04:22 Z

Ok, another RD issue that I can't seem to fix no matter many of the 'solutions' on the net I've tried. Here is my setup first:

Local workstation is Windows XP SP2
Remote server is Windows 2003 R2 SP2
Visual Studio 2005 (code is in C# if that matters)
Remote Debug Monitor is running with Windows auth. turned on.

My workstation is on the company domain (network) and the server is in our test lab (not on the domain). I can VPN to the server, open file shares, etc with no issues using the IP address and logging in as administrator.

The issue comes in when I try to use the remote debugger to step through some code in a Windows service that is running on the server. When I use 'default' as the transport and this as the qualifier, "xx.xx.xx.xx\Administrator@computername" I receive the following error: "Unable to connect to the MS VS RD Monitor named xx.xx.xx.xx\Administrator@computername. The debugger cannot connect to the remote computer."

If I try to connect with the setup (default transport) but using just the IP as the qualifier I get the following error: "Unable to connect to the MS VS RD Monitor named xx.xx.xx.xx. The MS VS RD Monitor does not appear to be running.". I have verified the monitor is running.

Now, if I change the RD Monitor to use no auth. and to allow any user to debug and then try to attach with 'Remote' as my transport and the IP as my qualifier I connect and can see the processes, including the one I need to debug. If I go ahead and attach to the service I can not hit breakpoints, "No native symbols in the symbol file". If I try to manually load the symbol file I get an error saying the files don't match (even though they do).

I've looked and looked and tried what seems like a thousand things to get this working and nothing seems to have any effect. Please, please can someone point me in the right direction?

Thanks,
Michael

Microsft.Ink.Load(bytes) Exception thrown (ASP.NET)

Thu, 15 Jan 2009 16:19:54 Z

I created a website. We stored ink into the database. I want to retrieve the ink and convert it to an image. I am having trouble with it. This is what I did.

byte[] b = GetTheInkFromDB;

if (b != null && b.Length != 0)
{

   Microsoft.Ink.Ink ink = new Ink();
   ink.Load(b);
   byte[] gifbytes = ink.Save(PersistenceFormat.Gif, CompressionMode.Maximum);
   ink.Dispose();
MemoryStream img_stream = new MemoryStream(gifbytes);
Image img = System.Drawing.Image.FromStream(img_stream);
img_stream.Close();

}

However, everytime it goes to ink.Load() an exception is thrown! It says: "Value does not fall within the expected range." I am doing this in asp.net. I don't know why I am getting this. Thank you guys!

ListView Item Selection only works in a "Window" not in a "UserControl" - SelectedIndex always 0 and SelectionChanged not fired

Wed, 17 Dec 2008 22:16:09 Z

Hi,

I'm trying to add a custom UserControl containing a Sortable-ListView (Tried with my own implementation and the AvalonControlsLibrary from Codeplex).

Everything is working fine, but I can't select any Item/Row and no item/row gets highlighted as selected, when I click on it.

I didn't change this type of behaviour (no code, no style, no template...nothing).

When I copy exactly the same code to a "Window" its working without any problem.....every row is highligted after clicking and the SelectionChanged Event gets fired.....

Can you tell me what Im doing wrong???

                gameMenuSelected++; 
            } 
        }       
 
    return;

How can I make it so that the loop doesnt run so quickly that it does it several times?

How do I enable RIP listener on Windows Server 2008?

Sat, 13 Dec 2008 23:53:22 Z

How do I enable RIP listener on Windows Server 2008?

The problem: there is no RIP Listener service in Services snap-in and there is no Iprip entry in HKLM\System\CCS\Services key.

Desired behaviour is the same that would be if you enable RIP listener in Windows XP.

Search gives only solutions how to enable RIP listener on Vista(through turn features on/off).

What I've done so far:

1. In Server Manager added role Network Policy and Access Services -> RRAS.

2. Configured RRAS as custom configuration where I checked only "LAN routing" checkbox.

3. Added RIPv2 protocol to the IPv4 node.$0 $04. Added LAN interface to new RIP node.

5. Configured LAN interface in RIP node in the next way: outgoing protocol - silent RIP, incoming protocol - RIP v1 and v2.

After all of this I have my routing table unchanged.

To ensure that RIP works correctly on my LAN, I've tried enable RIP listener on XP machine connected to the same switch and succeeded to observe major changes in route table.

Add-In: How to Enable\Disable menus in Visual Studio 2008

Tue, 09 Dec 2008 16:20:12 Z

Hi all,
Im developing an add-in for Visual Studio 2008 (.NET 3.5) which, while running, allows a new DTE mode (additional to debug & design).
I would like to disable some of the menus while entering this mode and enable them back afterwards.
for example disabling File->Open->Project.
I tried to do the following:

OleMenuCommandService mcs = GetService(typeof(IMenuCommandService)) as OleMenuCommandService;
CommandID cmdId = new CommandID(some_guid, some_id); // one of the menus I want to disable
MenuCommand mc = mcs.FindCommand(cmdId);
mc.Enable = false

but that didn't work. Do you have any ideas as for what I might be doing wrong ?

Mon, 08 Dec 2008 20:58:49 Z

Hi. I'm building an MFC app with VC++ 2008, but I'm having a little trouble. I've a CDockablePane with a property list, similar to the NewControls example that comes with the MFC Feature Pack. However, some of my properties are 'float' and I would like to format them with 2 decimal number (e.g. 34.56).

It seemed that the only thing I needed to do was set the following variable:

CMFCPropertyGridProperty::m_strFormatFloat = _T("%.2f");

This works as long as the property isn't manually updated. When the value is updated it triggers a breakpoint cause of the 'invalid format'.

Here's the stack.

Use LsaLogonUser for Protocol Transitioning and SSPI

Wed, 03 Dec 2008 13:58:43 Z

Hello,

I am wondering if the following is possible:

1. An account on machine A with the necessary privileges uses protocol transitioning through LsaLogonUser to acquire credentials for another user principal.
2. The Token Handle acquired through the LsaLogonUser function is then used to impersonate that user, through the ImpersonateLoggedOnUser function
3. AcquireCredentialsHandle and InitializeSecurityContext are then used to proove the impersonated principal's identity to another server (B).

The main goal would be for machine B to receive the impersonated credentials from machine A, so that B could the use them to prove authenticate against another service.

So far, I have successfully been able to use protocol transitioning with LsaLogonUser to log in with another principal. I then impersonate this principal successfully and call AcquireCredentialsHandle. All of this works fine, but when I call InitializeSecurityContext, it returns SEC_E_NO_CREDENTIALS.

So, is something like this possible and if so, is this a valid way of doing it, or is there another way?

Thanks for any help,

John

converting time to seconds

Concatenate multiple reports

Thu, 13 Nov 2008 21:52:26 Z

I have a task to create a Reporting Services local report which has 6 different sections 5 of which have a many to one relationship with the master record (An employee). I have accomplished it so that when the user selects the person, 6 stored procedures are run which return 6 separate data tables which represent the 6 data sources for the report.

It was originally presented to me as a "select a person, produce one report" so this seemed workable, until they decided they wanted to group the employees by cost center and product multiple pages for the report, one for each employee.

Given the data structure of 6 data sources I can not come up with a way to make it one report, so I would like to send each report to the viewer one at a time and then present the viewer at the end of all records.

Has anyone dealt with this kind of issue?

It would seem that I need a way to leave the stream open until I have sent multiple reports to the viewer

ReportViewer LocalReport memory leak

Thu, 16 Oct 2008 08:51:53 Z

We use ReportViewer control in asp.net to present rdl report by LocalReport mode, and find that the memory usage of asp.net process increasing obviously when we query report with large dataset. As if GC doesn't work at all.

There are few discusses about the topic via google and this thread is the most detailed:
http://social.msdn.microsoft.com/forums/en-US/vsreportcontrols/thread/d21f8b56-3123-4aff-bf84-9cce727bc2ce.

However ReportViewer.LocalReport.ExecuteReportInSandboxAppDomain() doesn't work. Some microsoft supporters said the problem will be solved in visual studio 2008 sp1.

We update visual studio 2008 sp1 and reportviewer sp1, and the version of ReportViewer is updated from 8.0.0 to 9.0.0. There are some features have been improved such as print function and pdf size decreasing. However the momory leak problem doesn't be solved in terms of out testing.

It's coming to our deadline to release the product and we hope to get some help.

Thx

How to call a method that takes inherited class as parameter?

Thu, 16 Oct 2008 21:56:40 Z

Hi,

I have a base class and some classes are inherited from it. I created some overloaded methods that takes those classes as parameters. In a method I only get an instance of the base class whose type is one of its descendant. How can I call it in an easy way? (not creating a Dictionary of inherited classes with values of Type etc.)

Here is an example:

class BaseClass{}

class InheritedA:BaseClass{}

class InheritedB:BaseClass{}

methods:

void DoSthing(InheritedA inst){}
void DoSthing(InheritedB inst){}

My calling code:

private void Method1()
{
BaseClass inst=new InheritedA(); //cannot change the way it is given
DoSthing(inst as ???? ) //I don't know what to insert here: inst as inst.GetType().Name? I really need the instance's class type

}

Probably there is an easy way I just don't get it now :)

C#: Winform - Filter on DataTable in DataGridView

Sat, 13 Sep 2008 07:57:20 Z

I have made a service that sends a datatable with person information to a client. In the forms init event I call the service to retreive all persons from my service and displays them in a datagridview.

In the form I want to be able to filter on e.g. first name. I have used the select method to filter on the datatable but it only returns datarows and not datatable which I need to set as datasource in my datagridview.

Also I can not add the datarows returned from the select statement to add to another datatable as they belong to the first datatable I created.

Does anyone know how I can solve this problem?

Create and Initialize Generic Stack

Wed, 27 Aug 2008 04:10:12 Z

I'm trying to get around the error that my stack is null as I cannot use it until I initialize it it seems.

        private Stack<int> currentStep = new Stack<int>();
        currentStep.Push(1);

I get an error: Invalid Token

I can't get this to work because I have a method that is trying to increment the stack and it keeps telling me it's null:

        public static void IncrementStack(Stack<int> s, int numberToIncrementBy)
        {
                // gets the current value (peek)
                // Add the new number to the stack (push)
                s.Push(s.Peek() + numberToIncrementBy); <--- I get a null exception here because the stack is null
        }

Running Code?

Wed, 26 Mar 2008 20:48:06 Z

Is “Running Code” necessary in the standardization process? Empirically the answer is yes. In the IETF a standards track RFC cannot achieve Draft Standard status without demonstration of at least two interoperable implementations developed from independent code bases. For digital media CODEC standards, reference decoders, encoders and bit streams are generally a required component of the standardization process.

In other cases, such as USB, PCI and WiFi the standards were developed from near production-ready technologies but not necessarily from independent, interoperable implementations. Cases of standards developed, or are being developed , from commercially available products include ISO/IEC DIS 32000 (Adobe PDF 1.1), ISO/IEC 26300 (OpenDcument Format),ECMA 376 ( Office Open XML), JPEG XR (HD Photo) and XPS. In these cases the Running Code consisted of pre-production silicon, many PDF implementations, OpenOffice, Microsoft Office and Microsoft Windows.

Personally I can’t recall an industry standard that didn’t have some level of implementation behind it at the beginning. Even in the cases of standards, like JPEG, that are purported to have started with a clean sheet of paper I’ll bet the technical contributions had at least been developed and implemented at the research level.

Perhaps the real question is whether standards organizations should rely on the IETF definition of Running Code or whether other forms of demonstrable or theoretical interoperability are acceptable.

What do you think?

What is the Interoperability Executive Customer Council?

Mon, 07 Jul 2008 19:04:49 Z

What is the IEC Council?

The Interoperability Executive Customer (IEC) Council has been mentioned several times in recent announcements and blogs on interoperability. As someone deeply involved in the IEC Council, I want to share what the IEC Council is, how it is advising Microsoft on Interoperability scenarios and issues, and what is being discussed.

I am the Technical lead on the IECC Core team at Microsoft. I lead the technical discussions within the council and work with various internal product teams to collaborate with the council and discuss solutions to interoperability issues raised by them.

The IEC Council is a customer advisory council consisting of CIOs and CTOs of about 35 large enterprises, from the public sector and private sector, and government departments from around the world. Launched almost two years ago, it has become one of our greatest sources of input on interoperability.

What are the Goals of the IEC Council?

Raise awareness around interoperability issues and solutions
Provide education on Microsoft’s interoperability strategies and programs and influence their design through customer feedback
Create strong connections between members to share knowledge and best practices

How is the IEC Council structured?

The council is divided into 6 work streams covering Microsoft products and services. It has yielded a great deal of in-depth analysis and examination of interoperability scenarios and issues. The work streams are:

1. Office Productivity and Collaboration Tools

2. Developer Tools and Runtime

3. Systems Management

4. Security and Identity Management

5. Business Process Modeling

6. Public Interoperability Policy

In these work streams, customers tell us why they are using our products in the way they do, what are they trying to interoperate with, and what issues they run into. We discuss our strategy and goals around our products and services, collaborate to find best possible solutions, and provide guidelines for our products and policies around interoperability. Many of our recent announcements were heavily influenced by the council. In my next post, I will go into more detail about each of the six work streams.

How the Interoperability Executive Customer Council works

Mon, 07 Jul 2008 19:03:24 Z

Interoperability Executive Customer (IEC) Council, Volume 2 – How it works

In the post titled "What is the Interoperability Executive Customer Council," I mentioned the six IEC Council work streams. Here is a little more about each one.

Work stream #1: Office Productivity and Collaboration Tools

Major interoperability scenarios discussed under this work stream are around Office file formats, Office programmability and automation, Document and Content Management Servers, Backend and Line-of-Business Apps integration, etc. Customers want their information workers to be able to use a variety of tools to manipulate back-end data in a collaborative and intuitive way to help make business decisions and to easily process business documents, etc. They also want to exchange documents across systems and platforms and manipulate those using well-documented APIs and protocols. They need to feed backend data (from databases and Line-of-Business apps) into Office documents.

Many customers are using more than one content and document management server collaboratively in their organizations or with their partners. They want to integrate Search, UI, metadata, content management, personalization and taxonomy across multiple portals.

Other interoperability scenarios are around email and calendar interoperability, instant messaging, chatting, online meetings and information rights protection.

Work stream #2: Developer Tools and Runtime

Developers want the ability to use different development tools in a distributed environment. They want to be able to develop software applications using a mix and match of various tools and programming languages and manage the whole process using some common repositories and business processes.

Demand for protocol level interoperability between .NET and Java/Mainframe apps is also very high. There is also some demand for binary interoperability between the .NET and Java/Mainframe stacks in some instances.

Work stream #3: Business Process Modeling

Here we discuss how to facilitate design, development and management of business processes to run across multiple platforms and systems, with the ability to use different tools and frameworks in an interoperable way to do architecture modeling and implementation. There are many interoperability challenges and we are trying to understand how models (and modeling tools) are used in different organizations, what their lifecycle is and what standards are important for data and model interchange, etc.

Work stream #4: Public Interoperability Policy

The goals of this work stream are to guide Microsoft in its application of Interoperability Principles and inform public policy positions related to innovation, interoperability, privacy and security. Basic discussions have been around how Microsoft can clarify its interoperability strategy and foster interoperable systems thru technology, licensing, documentation, partner ecosystem and other means.

Work stream #5: Systems Management

Major scenarios discussed under this work stream are around IT operations management, deployment and patching of software, virtualization environments, etc. IT operations want to optimize management of heterogeneous enterprise environments while providing top-notch service to users based on their SLAs. Examples are how you use monitoring products from various vendors and make them work together to provide a reliable, integrated management experience in their data centers, use virtualization for consolidating servers and improving utilization of data centers, and automate software deployment, patching and asset inventory across their environments to lower total cost of ownership.

Examples of how the council is guiding product teams to add interoperability features will be shown in the upcoming release of Systems Center products which will contain support for managing VMWare environments in the Virtual Machine Manager and will have new connectors in Operations Manager for other 3^rd party tools.

Work stream #6: Security and Identity Management

Major interoperability scenarios include identity federation for providing secure access to internal resources to partners and customers, single sign-on techniques, user-centric and claims-based authentication approaches (like infocards/CardSpace) for identity management through 3rd party providers and relying parties, and ActiveDirectory-LDAP integration etc. Other scenarios are around synchronization of items and passwords, etc., across multiple directories like ActiveDirectory and LDAP. Scenarios where applications need to continue working when one of the directories is inaccessible, by switching over transparently to get required info from another fail-over directory, were also discussed. Customers also want to streamline the process of user provisioning and want to be able to delegate that work to selected partners in some scenarios.

I hope this information will provide some insight into the practical methods Microsoft is employing to deliver on interoperability principles and standards, and I welcome your input to the Interoperability Forum
