SemdMessage Help PLEASE !!!!

Hi,

I know there is an API - SendMessage - to change Title OR Caption of other window-program, I also know That i will need the hWnd. What is the function ? How can i invoke it?

Thanks

Hi,

what u'll need to do is first find the handle of the window. For this u can use the FindWindow API. Once u've got the handle use the SendMessage API to change the caption.

Code:

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Const WM_SETTEXT = &HC

Private Sub Command1_Click()
Dim x, y
x = FindWindow("Notepad", vbNullString)
y = SendMessage(x, WM_SETTEXT, ByVal CLng(0), ByVal Text1.Text)
End Sub

Text1 --> a textbox where the new caption is entered.

Im changing the caption of a notepad file. U can locate any file u want by changing the parameters of the FindWindow API. If u need, u can check

for more info on the FindWindow API.

Hope this is what u want.
