How can I have all all apps to be refreshed on changed workspace size

I've added code to my project to resize the desktop, but can't seem to have all apps automatically refreshing with change. Any ideas.

You could try repainting the desktop

VB Code:

Private Declare Function InvalidateRect Lib "user32" (ByVal hwnd As Long, lpRect As Long, ByVal bErase As Long) As Long
 
'Function call
InvalidateRect 0&, 0&, False
