I've used MFC dialogs before where you do: EnterNameDlg dlg; dlg.DoModal(); string str = dlg.GetName(); However a dialog I have now actually looks at a list-box control in such a method and it's not working. Although the class instance clearly exists after DoModal(), does the actual dialog get destroyed? I noticed calling DoModal() a ...
I have a CFrameWnd with a dialog bar, and I'd like to determine the paintable area (excluding the space used by the dialog bar) so I can draw in it without being overlapped by the dialog bar. How can I do this? GetClientRect() seems to cover the client rect area as well, and I don't see any other obvious candiates in the doucumentation. ...

I am working on an MFC app that seems to be automagically committing to ~160MB of virtual memory. The app typically runs at 10-14MB of memory usage so this level of committed memory seems excessive. Additionally there is no where in the code where VirtualAlloc is called... COM & ATL are also being used. The memory shows as committed t...

To think ... there I have been happily programming in an MFC riddled environment for years, using ASSERT() whenever it seemed OK and just today I (was) stumbled upon the VERIFY Macro: http://msdn.microsoft.com/en-us/library/fcatwy09%28v=VS.71%29.aspx It's basically the same as ASSERT() except the expression will not be removed in releas...
I'm trying to figure out how to use the CDockablePane. But the just a few total overloaded demo samples (look like marketing samples not intended for programmers) i can't find any Tutorial kind. And the reference is heavy for a medium skilled MFC hacker like me. EDIT: This is the only documentation i have at the moment: MSDN VS2010 M...

My application has a tree of type CTreeCtrl. One of the nodes of the tree is CComboBox control created as a child of this tree structure. c_combo->Create( WS_CHILD | WS_VISIBLE | WS_VSCROLL | CBS_HASSTRINGS | CBS_DROPDOWNLIST, myrect, m_pTree, IDD_OBTC_COMBO ); In essence, the ComboBox gets created when clicked on the tree node and we...

Also, when I try the following: CStdioFile file; CFileException exc; bool bSuccess = (file.Open(_T("FileDNE"), _O_RDONLY, &exc) == TRUE); ASSERT_FALSE(bSuccess); CString err; exc.GetErrorMessage(e...

My application consists of a custom tree derived off of MFC CTreeCtrl. I handled the ON_WM_LBUTTONDBLCLK such that when I double click on a particular tree item, it changes to a combobox and ON_CBN_KILLFOCUS will destroy the combobox and reset the tree item. Double clicking the tree item creates a combobox but left clicking an item afte...
