?¿?¿? May I have a little help please ?¿?¿?

[Daniel_Christie]

Ok, I am hoping to make my program send text to a 3rd party program's specific textbox. This 3rd party program has several textboxes and I need to target a specific one. I naturally do not have the 3rd party program's source code. If you where in my shoes, what would you do to get a 3rd party program's specific textbox handle?

p.s. I thought I had it licked when I used a hWnd spy program. It told me the specific textbox's hWnd. But the hWnd was differnt the next time the 3rd party program was launched.

As always, any help is greatly appreciated,
Daniel Christie

The only way I can think of is to see what the Index of the Edit box is in the Spy program you're using, by Index I mean Instance, is it the 3rd Edit box, the 2nd, etc..

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
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long

Private Const WM_SETTEXT = &HC

Private Sub Command1_Click()
    Dim lHwnd As Long
    Dim sText As String
    Dim iIndex As Integer
    Dim lChildWnd As Integer
    
    sText = Text1
    lHwnd = FindWindowEx(0, 0, "3rdParyAppClass", vbNullString)
    For iIndex = 1 To 5 'Change 5 to Index Number of Editbox to Find
        lChildWnd = FindWindowEx(lHwnd, lChildWnd, "Edit", vbNullString)
    Next
    SendMessage lChildWnd, WM_SETTEXT, Len(sText), ByVal sText
End Sub

What is a 3rd party program?

[Aaron Young]

A program written by a 3rd Party, ie. Commercial Software.

I used 3rdPartyClass just as a Filler, it needs to be replaced with the Class name of the Main Window of the 3rd Party Application.

Aaron Young,

Here is the source for the spy proggie I am refering to... If you can think of anything it lacks or needs, I'd be happy to listen.

add to .bas:

add to form1:

WindowSPY Text1, Text2, Text3, Text4, Text5, Text6, Text7, Text8, Text9
