Exceptions in Listview's NM_DBLCLK lock Listview
Posted on 1997-12-25
I have a listview. In the handler for it's NM_DBLCLK, I throw an exception, which is to be caught in the primary message loop of the application. The exception handler shows a dialog box and allows message loop to continue getting/dispatching message.
The problem is that after the dialog box is shown, the listview locks - the scroll bars of the list view work, but no clicking or keyboarding seems to work on it (and no, it's not disabled).
I use VC++ 5 (Service Pack 2) under WinNT/Win95 (explorer 3 or 4) with MFC.
My reasoning is that the listview is not exception safe (remember, C++ exceptions are also Win32 exceptions).
So - is there a workaround, or am I doing something wrong? (and I know that doing the try/catch inside the NM_DBLCLK will probably work, but I'll save that as a last resort, because I do want to handle all my exceptions in a central place)
