I have started using a macro in Visual Studio 2008 that works fine in Visual Studio 2005.
In VS2008, the macro works but sometimes causes the Visual Studio Just-In-Time Debugger to appear
with "An unhandled win32 exception occurred in explorer.exe[3460]."
The debugger indicates:

I remember, when Visual Studio 2003 was released, my Add-In would run under
both VS 2002 and 2003, but only if it was compiled with VS 2002. If it was
compiled with VS 2003, then it was incompatible with VS 2002.
That was kind of annoying at the time.

I noticed that you can configure a component on your design surface by
setting the properties to whatever you want, and then drag the component to
the toolbox.  The Toolbox will create a toolbox item called "Template1" and
you can share that pre-configured component across forms ...

I'm trying to build a custom C++ wizard to build my projects, but I've come
unstuck trying to add a user property page.
In visual studio, I can create a file which is a Visual Studio Property
Sheet,  named for instance version.vsprops

I Have a real strange problem here,
I create a ToolWindow of an UserControl like this
---------------------------------------------------------------
 else if (connectMode == ext_ConnectMode.ext_cm_AfterStartup)
