Re: CFileDialog in Threads

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

1) subclass CFileDialog and create a class called CMyFileDialog
2) provide a OnInitDialog handler.
In that you can use the GetSafeHwnd(...) to get the window handle.

No use like this
CMyFileDialog dlg;
dlg.DoModal();
