Let's say a frame (or the child of a frame) starts another window. If one closes that second window with Alt+F4, also the frame gets closed.

The started window can be any window - frame, ordinary window, dialog, popup.

Other ways of closing the second window work fine.

Revelation - what's your opinion on this problem? What's the cause, can it be fixed, etc.

Don Bakke has experienced a similar problem with ESC and popups. I haven't been able to reproduce this other problem.

Don Bakke has a workaround that should work well in both cases, except it means a lot of work when there are many windows (e.g popups) in the app.

Other developers: How do you handle this problem?

[notag]I might be missing something but we use Ctrl-F4 to close children and Alt-F4 to close the lot. This is standard Windows behaviour?

If that second window is closed with Alt+F4 the parent, i.e, the frame, is closed too. I agree with what you say about using Ctrl+F4 to close a child and Alt+F4 to close the frame and all its children. I'm a bit surprised I didn't see the problem earlier, and that it's not caused more of a stir among other developers. But I've done some experiments with very simple windows now, so I'm certain it's not something caused by complicated design and programming in my main app. - Oystein - </QUOTE> —- === At 18 OCT 2001 12:45PM The Sprezzatura Group wrote: === <QUOTE>You might like to review this thread, which details how to Send a Windows message to close a Window. Here is another "last-resort" keyboard-macro approach coded in 32-bit Visual Basic - we realize that this might not be much help - but at least you have the relevant API calls, FWIW, should you adopt this method. Firstly use FindWindow to identify the handle of the Window to close, <code> Private Declare Function FindWindow Lib "User32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Dim Ret As String Ret=Untitled - Notepad" ' Find the window - put Window Title into the variable 'Ret' above Winwnd=FindWindow(vbNullString, Ret) If Winwnd=0 Then ' no window found Exit Sub End If </code> then show the Window maximized/normal, with focus set <code> Private Declare Function ShowWindow Lib "User32" _ (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long Const SW_SHOWNORMAL=1 'Show the window/provide focus ShowWindow Winwnd, SW_SHOWNORMAL </code> then fake the appropriate keystrokes to close it - exactly what someone would do under Windows manually. <code> Private Declare Sub keybd_event Lib "User32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long) Const VK_LCONTROL=&HA2 Const VK_RCONTROL=&HA3 Const VK_F4=&H73 Private Sub PressCtrlF4() 'clear window with Ctrl-F4 Dim ctrlscan%, f4scan% 'Depress Ctrl - the Left one on this occasion keybd_event VK_LCONTROL, ctrlscan%, 0, 0 DoEvents 'Depress F4 keybd_event VK_F4, f4scan%, 0, 0 DoEvents 'release F4 keybd_event VK_F4, f4scan%, &H2, 0 DoEvents 'release the Control Key keybd_event VK_LCONTROL, ctrlscan%, &H2, 0 DoEvents End Sub </code> The Sprezzatura Group World Leaders in all things RevSoft </QUOTE> —- === At 19 OCT 2001 03:27AM Oystein Reigem wrote: === <QUOTE>Sprezzatura, Are we talking about the same thing??? It seems you think I have problems with getting a window to close. It's the opposite. Too many windows get closed. What I have is an MDI window that starts a second window, e.g a dialog box. When the user hits Alt+F4, that second window closes OK, but unfortunately so does also its parent - the MDI window. Does the same happen with you? - Oystein - </QUOTE> —- === At 19 OCT 2001 08:54AM Don Miller - C3 Inc. wrote: === <QUOTE>Oystein .. Yup! I've had to resort to trapping the ALT-F4 combination in dialogs (essentially the CLOSE) event. I think the CLOSE event ripples up the event chain to the parent. As an aside, on one of my client's Citrix box, the PAGE event minimizes the window to the task bar (but does do the PAGE event). Go figger that one. Cheers..
