GetWindowText... I wish

[Joey_k29]

I am trying to use the GetWindowText API call in order to retrieve the caption that appears in the spy++ window. It is returning no value. I am using this syntax GetWindowText orig, caption, 100. I have tried sending both of the last parameters byval. I noticed I am incapable of getting wm_gettext to work correctly as well. I always get a null string. Orig is a long, caption is a string. Any help woudl be much appreciated. Thank you very much.

if what you really want is the title of the window, this will work:

It was pretty much stolen from the friendly folks at KDP
http://www.allapi.net/


you send it a unique PART of the string. if you send it something
that is contained in 2 open windows, you get the first one it
encounters.

Function WindowTitle(Optional appTitle As String, _
                       Optional apphandle As Long) As String
'   This function will return the Application Title and AppHandle
'       as a delimited string:  "This is the title|1234"

    Dim dummyVariable As Long, Ret_Handle As Long
    Dim lenTitle As Integer, Ret_Val As String
    Dim WinTitle As String * 255


    Ret_Val = ""
    If appTitle = "" And apphandle = 0 Then GoTo Xit_WindowTitle
        
    WinTitle = String(255, Chr$(0))
    If appTitle > "" Then  'A title or partial title was passed.  Search
       apphandle = GetTopWindow(0)
       Do Until apphandle = 0
           dummyVariable = GetWindowText(apphandle, WinTitle, 255)
           If InStr(WinTitle, appTitle) Then
              Ret_Handle = apphandle
              apphandle = 0
           End If
           apphandle = GetWindow(apphandle, GW_HWNDNEXT)
       Loop
    Else     'No title.  Must be appHandle
       dummyVariable = GetWindowText(apphandle, WinTitle, 255)
       Ret_Handle = apphandle
    End If
    Ret_Val = Left$(WinTitle, InStr(WinTitle, Chr$(0)) - 1) & _
              "|" & _
              LTrim$(Str$(Ret_Handle))
     
Xit_WindowTitle:
    WindowTitle = Ret_Val
End Function

it requires:
Private Declare Function GetWindowText Lib "user32"
Alias "GetWindowTextA"

I am trying to obtain the caption that spy++ retrieves when you use select a window. This caption does not have to be of a "window" persay. It can obtain the caption of a button, a picture, etc. Thank you for the suggestion, but that will not work for what i need.
