How to programmatically move Windows taskbar?

Question

I\'d like to know any sort of API or workaround (e.g., script or registry) to move (or resize) Windows taskbar to another position including another monitor (if dual monitors).

Answer 1

I also have this need on Windows 7. Here is my take to do this using autohotkey script:

; This script will try to drag and move the taskbar to where the *current* mouse
; cursor is

; 0x111: WM_COMMAND, 424: lock/unlock taskbar, http://www.codeproject.com/KB/miscctrl/Taskbar_Manipulation.aspx
RegRead, TaskbarLocked, HKEY_CURRENT_USER, SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced, TaskbarSizeMove
If TaskbarLocked = 0
  SendMessage 0x111, 424, , , ahk_class Shell_TrayWnd   

WinActivate ahk_class Shell_TrayWnd
MouseGetPos targetX, targetY
ControlGetPos x, y, w, h, MSTaskListWClass1, ahk_class Shell_TrayWnd
MouseMove x+1, y+1
MouseClickDrag Left, x+1, y+1, targetX, targetY, 10

; often after dragging the taskbar to left or right side of a monitor, even though
; there are enough room to show two columns of icons, it will only show one column,
; it seems showing or hiding an icon will fix this
Menu, Tray, NoIcon
Menu, Tray, Icon

; lock the taskbar if it was previously locked
If TaskbarLocked = 0
  SendMessage 0x111, 424, , , ahk_class Shell_TrayWnd   

I have tested this on Windows 7 with classic window theme. To use this, assign a hotkey to call this script, then position mouse cursor to where you want to drag the taskbar to, then press the hotkey.
