I have a couple of VB.NET functions as follows:

        Private Function EnumParentProc(ByVal hWnd As IntPtr, ByVal lParam As IntPtr) As Boolean

        Dim sb As New StringBuilder(256)

        GetWindowText(hWnd, sb, sb.Capacity)

        Dim windowText As String = sb.ToString()

        'If (windowText.ToString = "<main program>") Then
        If (windowText.ToString = "<sub program within main>") Then

            MsgBox(windowText.ToString)


            EnumChildWindows(hWnd, ecp, IntPtr.Zero)

        End If

        Return True

    End Function



Private Function EnumChildProc(ByVal hWnd As IntPtr, ByVal lParam As IntPtr) As Boolean

        Dim className As New StringBuilder(256)

        GetClassName(hWnd, className, className.Capacity)

        If className.ToString.StartsWith("<class name within sub program>") Then

            MsgBox(className.ToString)
            MsgBox(hWnd.ToInt32)
            MsgBox(lParam.ToInt32)

            Dim textLength As Integer = SendMessage(hWnd, WM_GETTEXTLENGTH, IntPtr.Zero, IntPtr.Zero)
            Dim windowText As New StringBuilder(textLength + 1)

            SendMessage(hWnd, WM_GETTEXT, windowText.Capacity, windowText)

            ComboBox1.Items.Add(windowText)

            MsgBox(windowText.ToString)

        End If
        Return True

    End Function



Basically, this tries to grab a handle to a class within a program.  However, the issue is that there happen to be two objects with the same class name within the program, and I only want the handle of the first of these.

I'm using WinspectorSpy to spy on the objects, and according to it the one class I want has an "ID" of 100, while the one I do NOT want has an "ID" of 101.

Is there some way to not only use the ClassName, but also use the ID, so that I can pick the one of these two which I want to send messages to?

Forgive me if I'm mangling the terminology, I'm in the process of teaching myself about the Win32 API and I haven't got all the terms straight in my mind yet.  I can post the entire source code I have so far if that'll help; it currently enumerates both like-named classes and shows msgboxes for each with the class name and I guess the handle (integer).

Thanks in advance for any help, I would greatly appreciate it.  :)
