Hello,

I would like to know whether it is possible to display a MFC window as part
of my VSIP package in Visual Studio. There is small part of my legacy
application I must preserve, and I would like to display one of the windows
in Visual Studio. The window I would display is a specialization of
CFrameWnd.

Any and all feedback is appreciated. Thanks,
Notre

Hi Notre,

To display your own MFC window within a native VsPackage should be OK.

I found you posted a related problem in vc.mfc newsgroup, and some
community members have already suggest the approach to you. Wish it helps.

Thanks!

Best regards,

Hi Gary,

Thank you for taking the time to respond to my question. I have
encapsulated the wanted part of my MFC code in a regular DLL that has MFC
support. I've been able to use a Win32 EXE and LoadLibrary/GetProcAddress
calls to load my code and display my dialog successfully. I've even managed
to get this to work with a WinForm host, using DllImport attribute.

However, when I try this in a VSPackage, my call to LoadLibrary fails. My
VSPackage is just the C++ VSIP wizard generated sample, modified to use
LoadLibrary/GetProcAddress instead of displaying the wizard generated dialog
box (after the user selects the appropriate menu item). I modified my code
to use LoadLibraryEx with the LOAD_LIBRARY_AS_DATAFILE flag. This allowed
the DLL to load, but of course I can't call any exported functions. I
verified that I'm not missing any dependencies that the DLL uses by using
dumpbin /dependents. Is there anything unique to the VSPackage or VS window
architecture that is preventing my DLL with MFC support from properly
initializing...?

Thanks,
Notre

It looks like if I remove one of my static dependencies in my DLL, then it
will load even from VS. So, although it should be in the DLL search path
it's not being found it seems. I'll dig a little deeper and see if I can
figure out what's going on.

(Maybe it needs to be in the same folder as devenve.exe ...)

Yes, my DLL search path was incorrect. After moving the dependent DLL to the
same folder as devenv.exe, everything worked correctly.
