[RESOLVED] Help Change a Title of Another Window

[stephen weber]

Hi,

I am trying to learn how to manipulate other opened windows from a VB.NET program. In this case I want to change the title of a particular IE window when/if it opens. That is a hotmail sign in account.
The code works fine up to finding the correct window and I see it remove the title "Sign In - Microsoft Internet Explorer" but it just leaves it blank?

Am I declaring something wrong . I mean HELP!!!

Public Class Form1
 
     Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
      Declare Function SetWindowText Lib "user32" Alias "SetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String) As Long
   
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Timer1.Interval = 1000
        Timer1.Start()
    End Sub
 
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
 
        Dim name As String = "IEFrame"
        Dim title As String = "Sign In - Microsoft Internet Explorer"
        Dim handleofwindow As Long = FindWindow(name, title)
        If handleofwindow <> 0 Then
          
            SetWindowText(handleofwindow, "What are you doing?")
 
        End If
       
 
    End Sub
 
 
 
End Class

In VB.Net Long variables from VB6 translate to Integer variables. Other than that I can't help

Heres the correct .NET declarations:

Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" ( _ 
     ByVal lpClassName As String, _ 
     ByVal lpWindowName As String) As Int32
Declare Function SetWindowText Lib "user32.dll" Alias "SetWindowTextA" ( _ 
     ByVal hwnd As Int32, _ 
     ByVal lpString As String) As Int32

If you still can't seem to get SetWIndowText to work, you can also use SendMessage with the "WM_SETTEXT" constant in order to set the text to what you want. The "APIViewer 2004" link in my sig has a .NET mode with all the correct .NET declarations of the API functions (as well as types and constants). Remember to set it to .NET mode in the options, as it starts in VB6 mode.

it looks like that should work if you declared everything properly like they have mentioned.

Thanks,

That was the solution. I must remember VB.NET uses INTeger (int32) instead of Long.
