You should write a BHO for this purpose Show/Hide a toolbar 2sky2-Nov-01 4:58 2sky 2-Nov-01 4:58  Can anyone tell me how to hide or show a toolbar on the MainFrame window from another thread. When I do something like: frmMain->m_canvasToolBar.ShowWindow(SW_SHOW); the function returns FALSE. And when I try to use: frmMain->ShowControlBar(&frmMain->m_canvasToolBar, TRUE, FALSE); the application crashes deep down inside the MFC core. Re: Show/Hide a toolbar PJ Arends4-Nov-01 17:31 PJ Arends 4-Nov-01 17:31  I would post a user defined message from the thread to the main frame. In the main frame, have a message handler that calls ShowControlBar(); --- It may be that your sole purpose in life is simply to serve as a warning to others. Exception handling ...

Carlos Antollini2-Nov-01 5:18 Carlos Antollini 2-Nov-01 5:18  Hadii, the function is global, but if youwant to use that function only in two cpp, you need to include in each cpp the header where the function is declared. You will see that you can use the function only in these cpp. Carlos Antollini. Re: Exclusive defines ! Hadi Rezaee2-Nov-01 5:37 Hadi Rezaee 2-Nov-01 5:37  But how can i include .cpp files ?

I can compile my circle.c but the linker is not quite amused about it and throws the (german only) exception: --------------------Konfiguration: U1 - Win32 Debug-------------------- Linker-Vorgang läuft... libcd.lib(wwincrt0.obj) : error LNK2001: Nichtaufgeloestes externes Symbol _wWinMain@16 Debug/U1.exe : fatal error LNK1120: 1 unaufgeloeste externe Verweise Fehler beim Ausführen von link.exe.

Re: Linking problem with C++ 2-Nov-01 3:53 2-Nov-01 3:53  It wasn't defined. I defined _UNICODE now, but nothing changed. Thanks anyway, Tim Re: Linking problem with C++ 2-Nov-01 5:08 2-Nov-01 5:08  Here is what the german MSDN says: Wenn Sie Unicode und MFC verwenden, werden Sie in dem Fall, daß Sie keinen Einsprungpunkt für wWinMainCRTStartup erstellen, einen unaufgelösten externen Verweis auf _WinMain@16 erhalten. Verwenden Sie die Option /ENTRY, oder geben Sie diesen Wert in das Dialogfeld Projekt-Einstellungen ein. (In der Entwicklungsumgebung finden Sie diese Option, indem Sie im Menü Projekt auf Einstellungen, dann auf die Registerkarte Linker und anschließend im Feld Kategorie auf Ausgabe klicken.) Beachten Sie dazu auch das Thema Unicode-Programmierung: Übersicht. perhaps you might try to use the linker-option /ENTRY, although I don't think this is the point Re: Linking problem with C++ Tim Deveaux2-Nov-01 11:14 Tim Deveaux 2-Nov-01 11:14  Well, wWinMainCRTStartup is set as the entry point in your settings. This is usually only necessary (IME) for apps with _UNICODE defined, and is not something I have seen in an app wizard generated project. Maybe you are modifying a standard sample. One suggestion is that the OpenGL libs (or the one you are linking with) is/are not enabled for unicode, and that's whats causing the problem. Another is that you are using the standard version of VC, which does not (by default(?)) install the debug unicode dlls. I'd try removing that entry point in the link settings.
