Edit Controls

23 Aug 2023 by Rick York

It is not entirely clear what you are trying to do. You state you want to have an edit control update itself but then you list it as CServicesDlg::EdtCompanyName(). That is clearly a method of a dialog class and it is unclear what relationship...

MFC app - find if specific username wrote correct password

6 Sep 2023 by OriginalGriff

We can't tell, we have no access to your code while it is running, so we have no idea what is in m_RadIsntExist or what it should contain. So, it's going to be up to you. Fortunately, you have a tool available to you which will help you find out...

MFC app and run command "rundll32.exe dsquery.dll, openquerywindow"

MFC app and run command "rundll32.exe dsquery.dll, openquerywindow"

30 Aug 2023 by Dave Kreskowiak

Why would you want to launch an entirely separate process (rundll32) that will not communicate with your app at all? Using the query window will do nothing in your application. You app will never know the user did anything in that window because...

MFC app - write something in first edit control to see in second edit control

1 Sep 2023 by OriginalGriff

That's a little complicated, because generally speaking two instances of a control shouldn't even know that the other exists - it breaks OOPs principles if they do, unless one is the child of another (and parent-child is trivial, so I'm pretty...

You cannot expect there to be YouTube tutorials on every question you come up with. As already suggested, you should use the documentation to check what features are available in each control that you are using: CEdit Class | Microsoft Learn[^].

MFC app - edit control data from first dialog to second dialog

4 Sep 2023 by Richard MacCutchan

Your problem seems obvious because the message told you what it is : Quote: "Debug Assertion Failed!" "Services.exe has triggered a breakpoint." on line 628 { ASSERT(::IsWindow(m_hWnd)); return (int)::SendMessage(m_hWnd, BM_GETCHECK, 0, 0); } in...

You need to use the debugger. The most common case for your error, is that the control isnt correctly connected with some resource in the rc and wiward. ASSERT(::IsWindow(m_hWnd)): means that this object hasnt a window handle. So debug to find...
