How to find the Caption

I am running some shell command using which i execute some forms or some application, at this point i wanted to read the caption of the running form's caption.

Shell the program and add this code, assuming that the application launced will be the one with focus.

VB Code:

Private Declare Function GetForegroundWindow _
Lib "user32" () As Long
 
Private Declare Function GetWindowTextLength _
Lib "user32" Alias "GetWindowTextLengthA" (ByVal _
hwnd As Long) As Long
 
Private Declare Function GetWindowText Lib "user32" _
Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal _
lpString As String, ByVal cch As Long) As Long
 
Private Declare Function GetParent Lib "user32" (ByVal _
hwnd As Long) As Long
 
 
Private Function GetActiveWindowTitle(ByVal ReturnParent As Boolean) As String
   Dim i As Long
   Dim j As Long
 
   i = GetForegroundWindow
 
 
   If ReturnParent Then
      Do While i <> 0
         j = i
         i = GetParent(i)
      Loop
 
      i = j
   End If
 
   GetActiveWindowTitle = GetWindowTitle(i)
End Function
 
 
Private Function GetWindowTitle(ByVal hwnd As Long) As String
   Dim l As Long
   Dim s As String
 
   l = GetWindowTextLength(hwnd)
   s = Space$(l + 1)
 
   GetWindowText hwnd, s, l + 1
 
   GetWindowTitle = Left$(s, l)
End Function

Matthew: How, and from where, would you execute your code to the get caption of an open window?
