    1) i would like to correct you that it is a DOS command.
    you can execute it through command shell.

    2) it is more safer , easier way to configure the services at once

  • @Varu - Ill save you from surfing the net Smile I know it all, Networkign GURU Smile!!!

    net <-- this is a command

    i guess you guys try out this comand, it got lot of thinsg, you can know your computer name, the shares etc etc

    if you pass first command line arguement as send

    so with the help of that command you can send messages to another computer conencted in the lan.

    Syntax :
    NET SEND
    {name | * | /DOMAIN[:name] | /USERS} message

    I think most of you wont understand that Stick out tongue ill explain int.

    eg : net send IP "your message here"
                this  will send the specified message to the IP address.

    eg: net send PC_HOST_NAME "your message here"
                 This will send message to the specified PC_host_name
    eg : net send * "your messsage here"
                 this will send the message to all the hosts connected in the lan with the same subnet (DOMAIN)

    eg: net send /DOMAINStick out tongueC_HOST_NAME "your message here"
                 this will send message to the specified host in the specified name


    To use this net send features, you will have to enable the MESSENGER service.
    The messenger service is by default enabled in winxp, while its disabled by default in winxp sp2. Correct me if i am wrong.

    To enable the messenger service START > RUN > SERVICES.MSC
    in there find for MESSENGER right click it > properties, and set the STARTUP TYPE to AUTOMATIC.
    or alternatively you can start it manually by start > run  > cmd > net start messenger
    and stop it by net stop messenger

    Extra :
    net share <-- shows a list of all the shared folders / drives
    net localgroup <-- to know all the groups of users
    net user <-- list of users
    net use <--- you can map a network drive using this command

    Calls one batch program from another without stopping the parent batch program. The call command accepts labels as the target of the call. Call has no effect at the command-line when used outside of a script or batch file.

  • Yup, Choice cmd is the best for creating batch files.. but XP doesnot have the external file for using choice cmd.. even we didnt had it in out lab, which is the scenario almost everywhere and thus we were not asked the batch files in exams....

    But anyhow, i was able to find the external file of the choice cmd and its there lying somewhere...

    Anyhow i will 1st show you an example of the choice cmd...

    Code Snippet

    @ echo off
    :start
    Echo "Press 1 to execute batch1.bat"
    Echo "Press 3 to execute batch3.bat"
    Echo "Press 4 to execute batch4.bat"
    Echo "Press 7 to Execute Batch7.bat"
    Echo "Press q to Quit"

    choice /c:1347q /T:q,15 "Select Choice"

    If errorlevel==5 goto quit
    If errorlevel==4 goto bat7
    If errorlevel==3 goto bat4
    If errorlevel==2 goto bat3
    If errorlevel==1 goto bat1


    :bat1
    call batch1
    goto start

    :bat3
    call batch3
    goto start

    :bat4
    call batch4
    goto start

    :bat7
    Echo Seventh Batch File
    del count.txt
    call batch7
    goto start

    :quit
    Echo Sorry, you could not chain to any batchfile



    Try to study it and ask questions, it will become more interactive then...

  • Hey guys anyone tried netsend cmd??
    its a cmd used to send messages to another computer in LAN,
    now most of you wont be knowing about it as it doesnot work by default in XP, because there is activity that needs to be activated to run it on XP system...

    reply to know more about it.. because i will need to search for it again, as it has been a time since i used it..

  • I dont think net send will work across the internet. But yes, if you still want, then you can create a VPN with the two pc's on the internet, and then you can use net send to send message to the other pc Wink

    buddy.
    i would like to hear from you.
    go on.
    but i'm also not wrong naa buddy
    Monday, May 28, 2007 6:21 AM
  • You are not wrong,

    Let me 1st clear out the basics.. there are two types of cmds, internal and external... Internal cmds are defined in the command.com, where as external cmds are small utility programs that are called using their name in dos...

    So even if i write iexplorer, it can be called a cmd, because it is a utility prog that i m calling...
    now how does it works??
    We have a path in Dos, ie we define some areas of the harddisk where Dos can search for the executable files that we call, by default windows, system32 etc are in path....

    Now when we write a name of the exe file, 1st it is searched in the command.com then in the search path that is defined.. when it is found it gets executed or else dos will say no such cmd found....

    So iexplorer and mozila are all coming under this path, so when you write their name, they get executed... similar way you can find lot more to execute, like the best one i use is MSDEV to execute the VC++ program...

    now find lot more like this...
    Monday, May 28, 2007 8:51 AM
  • thanks varun for pointing a difference between internal and external dos commands...

     

    so sunil you were correct

     

    well this is a new dos command

     

    "call"

    Monday, May 28, 2007 2:52 PM
  • nice information buddy.
    but i would like to add something.
    there are still some commands which won't get executed if you will type on a RUN window.
    however, if you'll write the same command in the command prompt then you'll not have any problem.
    can you explain why?
    there are many bugs in windows.

  • Hey i just remmbered a very nice question..

    tell me the difference between using a call cmd to call another batch and wrting the name of the batch alone, i.e. directly calling the batch file without call cmd....

    And buddies, though the marking of the posts was a very good facility provided by forums, people have started using it for their own benefits only.. so its worthless asking people to mark the posts.. I mark each and every posts in my forums, so that even if you reply, i mark it so that it would become fair to all....

    Wednesday, May 30, 2007 6:33 PM
  • Looks like we need to discuss more on batch files. .so i have started a new thread specifically for the batch files.. we can disscuss all the details of the batch files, give out codes for the batch files, i have some where around 12 good batch files, and solve queries....

    You know where to find the link

    So come and discuss more on the batch files over there...
