Can I change the caption of a button?

A button on another program? If it is not a graphic but normal command button, do I send SetText or something?

As long as you have the hWnd...

VB Code:

Public Declare Function SetWindowText Lib "user32" Alias "SetWindowTextA" (ByVal hwnd As Long, _
                                                                           ByVal lpString As String) _
                                                                           As Long
 
Call SetWindowText(hwnd, "Some Text")
