Error Event Type: Clr20r3

Question

Hi everyone,

I've created a program in VB using Bluetooth (InTheHand API) and Serial Port to communicate with a device.  The program is working fine on some computers, but not on others.  After the install, when trying to run the program, a error message is showing up with following details:

Event Type: Clr20r3
P1: prog.exe
P2: 1.0.0.0
P3: 4ae9f2c9
P4: prog
P5: 1.0.0.0
P6: 4ae9f2c9
P7: d
P8: c6
P9: system.invalidoperationexception

When I created the installer for this program, Visual Studio added InTheHand.Net.Personal.Dll and Microsoft.VisualStudio.HostingProcess.Utilities.Sync.Dll dependencies.  I think the problem may come from there.  I tried to register them with regsvr32 in Command Prompt and it didn't work telling me "the file was loaded but has no entry point".  I'm using VS 2005 Professional.  Does somebody have an idea what I should do ?

Thank you,
Ilyas.

Answer 1

You cannot register .NET assemblies using regsvr32. You should use regasm tool.

Also try to add logging to your application using the Trace class. Then, log the InnerException of the InvalidOperationException as well so you can gather more information regarding the cause of the crash.

Thank you, I tracked down the crash with a sub in my application events:

    Partial Friend Class MyApplication
        Private Sub MyApplication_UnhandledException(ByVal sender As Object, _<br/>
        ByVal e As Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs) _ <br/>
        Handles Me.UnhandledException
            MsgBox("Exception found: " + e.Exception.ToString, MsgBoxStyle.Critical, "Exception: Program could not start.")
            e.ExitApplication = True
        End Sub
    End Class

It appears that the 32feet.Net (InTheHand) could not start because the bluetooth stack wasn't activated on the target computer.  The bluetooth stack could be activated by plugging a BT device on the computer.  Is it possible to activate it by code ?
