  • If it's not reproducable on the development machine, implement exception handling in your code and log all exception details to find the location.

    "But when i just installed this application on client computer it gave me error."  Did the installation process give the error or after starting the installed application?

  • As I am new bie, can you please be more specific. I can not use try and catch blocks because it's a very long code there. I will be thanks

  • Try..catch works independently from the length of the code. 

    Wrap the try..catch block around the whole code in each thread's main procedure like this:

       Shared Sub Main()
    
          Try
              'code goes here
          Catch ex As Exception
             'log exception details here
          End Try
    
       End Sub

    If you only have one thread and if you use the Application Framework, handle the UnhandledException event. Open the project properties, application tab, button "application events". A code window opens. At the top left combo, select MyApplication, in the top right UnHandledException. An event handler gets created. Log the exception details there, probably to a file. For example:

     IO.File.WriteAllText("D:\tmp\exception.txt", e.Exception.ToString)

    As soon as the exception occurs on the target machine, have a look at the log file. It contains a stack trace that should point you to the error line.

  • Hi fariad22,

    Welcome to the MSDN forum.

    Your issue has more relationship with CLR. I’d like to move this thread to Common Language Runtime forum. It will cost a little time to involve the members in this forum. I appreciate your patience.

    Sorry for any inconvenience and have a nice day.
