I need to a third party program assignment in the text box, and the HTML code is as follows, but always can't get a handle to the window? Hope everybody to help me see

Private Sub Command2_Click ()
Shell App. Path & amp; "\ VNC4 \ vncviewer exe," vbNormalNoFocus
Dim HWN As Long
Dim TWN As Long
HWN=FindWindow (vbNullString, "VNC Viewer: Connection Details")
TWN=GetDlgItem (HWN, 1002) '(with SPY + find)
SendMessage TWN, WM_SETTEXT, 0, "10.71.1.1 '//" enter the IP address
If HWN=0 Then
Label1. Caption="failure"
The Else
Label1. Caption="success"
Label2. Caption=HWN
End the If
End Sub

HWN is always 0
