Did anyone solve this?

It appears the module state has not been correctly managed.

Would adding the AFX_MANAGE_SATE macro in your routine that loads the skin help?

Also, with side by side MFC modules, I have found that one can mess up module states if an access violation or some other exception occurs and the module state switching that should occur doesn't happen. But usually I get an invalid context activation exception eventually when it does. Of course you are shutting down (?) and that might not happen. I use the debugger and turn on first chance exception handling (win32, in particular access violations but usually just all) and then run my workflow and see if I am trapping some exception we have been ignoring, say with catch(...).

Hi,

I am facing the same problem of crash in:
it ASSERTS inside the dll code.

BOOL WINAPI RawDllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID)
{
    hInstance;
    if (dwReason == DLL_PROCESS_ATTACH)
    {
#ifdef _AFXDLL
        // make sure we have enough memory to attempt to start (8kb)
        void* pMinHeap = LocalAlloc(NONZEROLPTR, 0x2000);
        if (pMinHeap == NULL)
            return FALSE;   // fail if memory alloc fails
        LocalFree(pMinHeap);

        // set module state before initialization
        _AFX_THREAD_STATE* pState = AfxGetThreadState();
        pState->m_pPrevModuleState = AfxSetModuleState(&afxModuleState);
    }
    else if (dwReason == DLL_PROCESS_DETACH && !__mixedModuleStartup)
    {
        // restore module state after cleanup
        _AFX_THREAD_STATE* pState = AfxGetThreadState();
Here >>        VERIFY(AfxSetModuleState(pState->m_pPrevModuleState) == &afxModuleState);
        DEBUG_ONLY(pState->m_pPrevModuleState = NULL);

#endif //_AFXDLL
    }
    return TRUE;
}

I am not sure of the reason, I commented the loadskin code as suggested here, but it still crashes.
It happens only in Debug mode of my application.
PS: codejock v16.2.6 and Visual Studio 2010, Windows 7 64bit

Request you to please help me wth the same.

Regards,
Kalyani

Sorry for the delay getting back on this - I have been away.

It was not project settings in the end, I noticed I was building in release so was not getting the assertion - duh.

However i have found a solution:

I was subclassing the m_hWndMDIClient in CMainFrame::CreateClient. If I call UnsubclassWindow in CMainFrame::OnDestroy then the problem goes away.

Hi, thanks for the help.

I am not sure what happened but the assert no longer happens and the app closes correctly. I did change a number of project settings for different reasons so I guess it could be project settings related.

If it reappears I will try your suggestion. Hopefully I won't have to.

Tim.

Hi;

Try this in your ExitInstance() function:

int CMyCoreApp::ExitInstance() {
XTPSkinManager()->LoadSkin(L"", L"");
return CWinApp::ExitInstance();
}

I've several DLLs used in my app and skinning too. But in my case the app closes without an assert.

Hi is there any update to this? I am just about to start debugging the same problem. Code Jock version 16.2.0. VS 2012.

Cheers,
