How to move/resize/reposition taskbar by code in win XP

[v***@hotmail.com]

Dear everyone,

I was trying to write some code to change size and/or position of taskbar in
WinXP. At first I think it's just a regular window so I tried:

HWND hwnd = FindWindow("Shell_TrayWnd", NULL);
MoveWindow(hwnd, a,b,c,d, TRUE); //a,b,c,d are desided position and size

But it doesn't work. Later on I noticed that I should use some
shellappmessage thus came up the following code:

APPBARDATA appBarData;
appBarData.cbSize = sizeof(appBarData); appBarData.hWnd = FindWindow(_T("Shell_TrayWnd"), NULL);
appBarData.uEdge = ABE_BOTTOM;
appBarData.rc.left = -2;
appBarData.rc.top = -2;
appBarData.rc.right = 1026;
appBarData.rc.bottom = 57;
SHAppBarMessage(ABM_SETPOS, &appBarData);
MoveWindow(hwnd, a,b,c,d, TRUE); //a,b,c,d are desided position and size

However, the code still doesn't work at all. Microsoft seems to prevent
people change size/position of taskbar.

How can I do that? Any help is appreciated.


Thanks,
Vince

What you've done seems to be in the right direction.

At least this article does something similar ( ABM_SETPOS, followed
by a SetWindowPos() ).

The code simply doesn't work. To make sure I call them correctly, I tried
ShappbarMessage(ABM_SETSTATE.....) and I'm able to change autohide and
alwaysontop property of the taskbar, so the hwnd and way to call function
should be correct.

Any one has done this before?

Thanks,
Vince

First question: why do you think you need to do that, behind the user's
back?
