[RESOLVED] Getting a window's caption by its class name

hey.
i was wondering if anyone could help me out on getting a window's caption. the thing is, i dont want to search just for the caption. so the caption has to be inside a specific class and search for that caption within that class. Heres the info

Window's Caption: GRPsuper9's Buddy List Window
Class Name: #32770

First thing is first, getting the whole caption out of the class name. then, i want it to get the username before the "'s Buddy List Window". in this case, GRPsuper9. but lets say i log in with Master, i want it to get master instead of grpsuper9.

can anyone help? if u need clairifcations, just post

Use FindWindow API. You can pass the classname and/or window caption. If you dont know what the caption will be then passing the classname along with vbNullstring will get the first window handle that matches. Then using GetWindowText passing the handle will get the caption.

i tried searching for the code. but since i dont understand api, i dont know which 1 to look @. can you post some code in here that would help my case?

Sounds like you dont have an API viewer so if you go over to allapi.net and download the API Viewer utility you will have them all and there is a definition and code exmple for FindWindow there too.

VB Code:

Private Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" ( _
                     ByVal lpClassName As String, _
                     ByVal lpWindowName As String) As Long

k. here is my code

VB Code:

Private Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
 
Private Sub Form_Load()
    MsgBox FindWindow("#32770", "GRPsuper9's Buddy List Window")
End Sub

but whenever i do that, it gives me 197210 in return. how would i make it search for the username tho?

That's because FindWindow() API returns a Long data type.

Here's a way if you know the class name:

VB Code:

Option Explicit
    Private Declare Function FindWindow Lib "user32" Alias _
                    "FindWindowA" (ByVal lpClassName As String, ByVal _
                    lpWindowName As String) As Long
    Private Declare Function GetWindowText Lib "user32" Alias _
                    "GetWindowTextA" (ByVal hwnd As Long, ByVal _
                    lpString As String, ByVal cch As Long) As Long
 
Private Sub Command1_Click()
    Dim buf As String, wnd As Long
        wnd = FindWindow([B]"yourClassHere"[/B], vbNullString)
            If wnd Then
                buf = String(100, Chr$(0))
                GetWindowText wnd, buf, 100
                buf = Left$(buf, InStr(buf, Chr$(0)) - 1)
                    MsgBox buf
            Else
                MsgBox "Cant find window..."
            End If
End Sub
