Hi,

You free it before all controls destroy self. so you can try move it to destructor or indeed manually clear SkinManager.

Hmm... please note that I have all CJ skins in a resource-only DLL. I load it in InitInstance and unload it in ExitInstance:

FreeLibrary(s_hSkinModule);

return CWinApp::ExitInstance();

}

Since the exception comes after unloading of the DLL, I suspected that code block was the culprit. Placing the following code above the FreeLibrary call did the trick:

XTPSkinManager()->RemoveAll();

Now, is that really necessary?!

Well, I know you changed/removed a critical section that caused the application to hang when exiting with an html help window visible. So the bug is real.

Perhaps it only occurs in Classic mode? I'll see if I can find a pattern later. I'll also try your solution, but even if it works there is most certainly a scary bug in the skin manager :(

Hi,

Sorry, can't reproduce it.

Maybe try manually Close it with something like

HWND WINAPI AfxHtmlHelp(HWND hWnd, LPCTSTR szHelpFilePath, UINT nCmd, DWORD_PTR dwData);

void CMainFrame::OnDestroy()

{

CXTPMDIFrameWnd::OnDestroy();

AfxHtmlHelp(0, 0, HH_CLOSE_ALL, 0);

}

Windows 7 x64, VS 2008 SP1, XTP 13.3.0 statically linked. Skin active.

Pressed F1 in my application to view help. Then quit without closing the help. BOOM! (It seems to crash on different locations between the runs.)
