Board index » Visual Studio » SetFocus problem.

Visual Studio160
My application has a hidden main display window that is never used. The

application hangs out in the system tray and has a couple of configuration

windows that can be opened from the system tray menu. The program has a

couple of odd-ball fatal error scenarios. When these happen, the program

displays a fatal error message using AfxMessageBox and it shuts down normal

processing. This includes stopping the system menu so that the config

windows can't be opened.



Here's the problem:



If the AfxMessageBox window is covered by some other program, I want the

action of right clicking my system tray icon to pop the AfxMessageBox window

to the top of the display priority so that the operator can see it. Is there

a way to tell the AfxMessageBox to come to the top?



My main program window is hidden and not used. I thought maybe setting focus

to that window would somehow cause the AfxMessageBox window to pop up. It

doesn't work.



Specifically I tried: ((CMainFrame *)AfxGetMainWnd())->SetFocus();



Any ideas?

Have you tried calling SetForegroundWindow() or BringWindowToTop() with your

main window. I think the message box will follow it if you bring your window

to the top of the stack.

Are you talking about AfxMessageBox calls you are issuing or something that is coming from

MB_SETFOREGROUND? MB_TOPMOST? Did you read the AfxMessageBox documentation? Take a look

at my Message Box Explorer.

Setting the focus does not move a window to the top.

Given that SetFocus is a method of CWnd, and AfxGetMainWnd returns a CWnd *, the cast is

pointless. In fact, if the symbol CMainFrame is defined in any context other than the

mainfrm.cpp, there's some design error. You didn't say what context this is defined in.



However, since SetFocus has nothing to do with bringing the window to the top, it serves

no useful purpose except distracting the focus from whereever it is supposed to be.

Hi Joe,



You say that as though those are actually listed in the AfxMessageBox

documentation.

Speaking of undocumented stuff, why does MB_DEFAULT_DESKTOP_ONLY break the

messagebox? If you add that flag to a message box it doesn't display the

message box.

Thank you! SetForegroundWindow() works great.



I'm learning... I'm looking into what everyone else said.



Thanks again.

Ah, I see they aren't. My aplogies. The MFC documentation is out-of-sync with the API

documentation.

Now we'll have to explain all the idiosyncrasies of the broken

SetForegroundWindow() behavior WinME+... I don't even know what would work

reliably.
