vc++ api question...........

hello folks,

i recently started playing with vc++ api for solidworks...

I have VC++ version 6.0 and SolidWorks 2001 plus...

i started with the solidworks add in app wizard which generated a
skeleton application with a toolbar and a menu bar built in...

i tried to build a dialog box class which can be invoked from the
toolbar and menu...however..the application hangs..immediately when
the dialog box appears...

solidworks issues a message saying that solidworks has terminated due
to an unhandled error...please contact your local support
representative for help in troubleshooting this problem...

can anybody please tell me what the problem could be....

thanks in advance..

This is a welcome message. Welcome in the wonderful world of c++ api!
Seriously, this happens in most cases when your program crashes or does
something wrong, you'll see it many times... What you have to do is:
1) run your program in the Visual Studio Debugger.
2) check the "Exceptions" under the "Debug" menu (visible only while running
the debugger) and set at least c00000005 "Access violation" to "Stop
Always". It might help to find what's wrong
3) put all your code in try/catch statements to exit smoothly from your
add-in if something goes wrong. Hopefully, SW will be able to continue after
that.
Good luck!

 

Found in the MSDN Library help about AFX_MANAGE_STATE
By default, MFC uses the resource handle of the main application to load the
resource template. If you have an exported function in a DLL, such as one
that launches a dialog box in the DLL, this template is actually stored in
the DLL module. You need to switch the module state for the correct handle
to be used. You can do this by adding the following code to the beginning of
the function:

AFX_MANAGE_STATE(AfxGetStaticModuleState( ));
This swaps the current module state with the state returned from
AfxGetStaticModuleState until the end of the current scope.

Example :
void CTest::CreateAlias()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
CDlgAlias dlg;
dlg.DoModal();
}

It may correct your problem

you're linking the wrong MFC dlls.
In project settings, C/C++ tab, select "Multithreaded DLL" under "Use
run-time library".
You must select this for all libs or dlls your project is using.
