How to programmatically move the windows TaskBar?

How to programmatically move the windows TaskBar?

Hi There,

Is it possible to programmatically move the Windows Tas

I've been attempting to write a simple C program that is capable of moving 
the TaskBar in Windows.
So far, I've stumple upon the ShellAPI function "SHAppBarMessage". I've 
attempted to use it,
but nothing is happening to my taskbar at all.  Please see below for my full 
code.

Can someone help?


Regards,
Jr


#include <stdio.h>
#include <windows.h>
#include <shellapi.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR 
lpCmdLine, int nShowCmd)
{
 HWND hWnd = FindWindow("Shell_TrayWnd", NULL);
 APPBARDATA abd;
 ZeroMemory(&abd, sizeof(abd));
 abd.cbSize = sizeof(APPBARDATA);
 SHAppBarMessage(ABM_GETTASKBARPOS, &abd);
 abd.rc.top = 300;
 abd.uEdge = ABE_RIGHT;
 SHAppBarMessage(ABM_SETPOS, &abd);
 MessageBox(NULL, "Done!", "Taskbar Refresh", MB_OK);
 return 0;
}

Hi,

You can use the following APIs to size/position Windows taskbar:

	SHAppBarMessage(ABM_GETTASKBARPOS, &pData);

	hTaskbar = FindWindow(L"Shell_TrayWnd", NULL);

	GetWindowRect(hTaskbar, &RECT);

	SetWindowPos(hTaskbar, NULL, X, Y, CX, CY,
					SWP_NOSENDCHANGING);
	ShowWindow(hTaskbar, SW_SHOW);

	UpdateWindow(hTaskbar);

	GetDesktopWindow();

	RedrawWindow(hDesktopWindow, NULL, NULL,
	RDW_FRAME|RDW_INVALIDATE|RDW_UPDATENOW|RDW_ALLCHILDREN);

	SystemParametersInfo(SPI_SETWORKAREA, 0, NULL, SPIF_SENDCHANGE);

Hi,

You can use the following APIs to size/position Windows taskbar:

SHAppBarMessage(ABM_GETTASKBARPOS, &pData);

hTaskbar = FindWindow(L"Shell_TrayWnd", NULL);

GetWindowRect(hTaskbar, &RECT);

SetWindowPos(hTaskbar, NULL, X, Y, CX, CY,
SWP_NOSENDCHANGING);
ShowWindow(hTaskbar, SW_SHOW);

UpdateWindow(hTaskbar);

GetDesktopWindow();

RedrawWindow(hDesktopWindow, NULL, NULL,
RDW_FRAME|RDW_INVALIDATE|RDW_UPDATENOW|RDW_ALLCHILDREN);

SystemParametersInfo(SPI_SETWORKAREA, 0, NULL, SPIF_SENDCHANGE);

Re: How to programmatically move the windows TaskBar?

Hi there again,

The below code is working, however, the problem is that the Taskbar is only 
repositioned temporarily - a few seconds and then it is return back to the 
bottom of the screen.

Can somebody please help as I want it to be permanently repositioned the 
taskbar at the top of the screen?


#include <stdio.h>
#include <windows.h>
#include <shellapi.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR 
lpCmdLine, int nShowCmd)
{
 RECT rect;
 RECT deskTopRect;
 HWND hDesktopWindow;
 char* strMessage = "Your Taskbar is now refreshed.";
 HWND hWnd = FindWindow("Shell_TrayWnd", NULL);
 APPBARDATA abd;
 ZeroMemory(&abd, sizeof(APPBARDATA));
 abd.cbSize = sizeof(APPBARDATA);

 SHAppBarMessage(ABM_GETTASKBARPOS, &abd);
 GetWindowRect(hWnd, &rect);
 SetWindowPos(hWnd, NULL, rect.left, 0, rect.right, rect.bottom-rect.top, 
SWP_NOSENDCHANGING);

 ShowWindow(hWnd, SW_SHOW);
 UpdateWindow(hWnd);
 GetWindowRect(hWnd, &rect);

 hDesktopWindow = GetDesktopWindow();

 GetWindowRect(hDesktopWindow, &deskTopRect);
 deskTopRect.top = rect.bottom;
 RedrawWindow(hDesktopWindow, NULL, NULL, 
RDW_FRAME|RDW_INVALIDATE|RDW_UPDATENOW|RDW_ALLCHILDREN);
 SystemParametersInfo(SPI_SETWORKAREA, 0, (LPVOID)&deskTopRect, 
SPIF_SENDCHANGE);

 //SystemParametersInfo(SPI_SETWORKAREA, 0, NULL, SPIF_SENDCHANGE);
 UpdateWindow(hDesktopWindow);

 MessageBox(NULL, strMessage, "Taskbar Refresh", MB_OK);
 return 0;
}
