How to lock taskbar in my program
-
As you know, we can lock taskbar manually, But I would like to lock taskbar by my own program. I try to do it by the following code: DWORD style = GetWindowLong(hShellTrayWnd,GWL_STYLE); style &= ~WS_SIZEBOX; SetWindowLong(hShellTrayWnd, GWL_STYLE, style); Unfortunately, it didn't work as I expected. Does anyone know how to do it? Your help would be greatly appreciated. Nothing impossible, Nothing sure

I did do it sometime back but don't have the message number with me now. :doh: Maybe I can give it you tomorrow. This requires you to send a message to the taskbar asking it to lock itself. I did have the number but don't have it now. :)

Hi Tomas, Your help would be greatly appreciated, in fact I send WM+USER+336 to taskbar, but it didn't work, which make me feel that it can't be done by sending a message. And then I try another way below: CToolBar* trayWnd = (CToolBar*)FromHandle(hShellTrayWnd); DWORD barStyle = trayWnd->GetBarStyle(); barStyle |= CBRS_SIZE_FIXED; trayWnd->SetBarStyle(barStyle); It also didn't work, I was really frustrated, the style of taskbar vary every time even though I remove "trayWnd->SetBarStyle(barStyle)". For example, sometimes barStyle is 380, but sometimes it is 376, and other times, it is another value. it is very strange for me. Nothing impossible, Nothing sure

Thanks. This works on both Windows XP, 2000...
//custom message
#defineWM_USERDEF_LOCKTASKBAR424static HWND hShellWnd = ::FindWindow(_T("Shell_TrayWnd"), NULL);
if(hShellWnd != NULL)
::PostMessage(hShellWnd, WM_COMMAND, MAKELONG(WM_USERDEF_LOCKTASKBAR, 0), NULL);
else
hShellWnd = ::FindWindow(_T("Shell_TrayWnd"), NULL);This will work!:)

It did work well, thank a lot. I have another question if you wouldn't feel disturbed, Actually I use spy to monitor taskbar, if my program send such WM_COMMAND msg to taskbar, spy can capture it. But if I do it manually by using winxp functionality, spy didn't show this msg, that is why I always can't get this msg. Could you be so kind to teach me something about it? Nothing impossible, Nothing sure

Thanks for your help. I mis-thought there had not benn reply yet because I didn't receive the response mail as usual, maybe last time I missed to check "Notify me by e-mail if someone answers this message". My email is : NianHawk@invalid.hotmail.com (please discard "invalid"). Which functionality! ===> I just lock the taskbar by taskbar menu. Best regards. Nothing impossible, Nothing sure
