I know how to capture Itunes ID and get information and child processes  then I want to be able to actually read all the items in the list view.  If possible.

I'm looking to enumerate to the max and get information on a different application.  Like how many buttons, sliders, listview and its detial.




I start with

        Dim item As ListViewItem

        For Each p As Process In Process.GetProcesses

            item = New ListViewItem

            item.Text = p.Id

            item.SubItems.Add(p.ProcessName)

            Me.ListView1.Items.Add(item)

        Next

Or for more information
 

        Dim p As Process

        Dim items(5) As String

        Dim r As New RECT()
 

        ListAll.Enabled = False

        ListView1.BeginUpdate()

        ListView1.Items.Clear()

        For Each p In Process.GetProcesses

            items(0) = p.ProcessName

            items(1) = p.Id.ToString

            If Not IntPtr.Zero.Equals(p.MainWindowHandle) Then

                items(2) = p.MainWindowHandle.ToString

                If GetWindowRect(p.MainWindowHandle, r) <> 0 Then

                    If IsIconic(p.MainWindowHandle) = 0 Then

                        items(3) = "(" & r.Left.ToString & ", " & r.Top.ToString & ")"

                        items(4) = (r.Right - r.Left).ToString & "x" & (r.Bottom - r.Top).ToString

                    Else

                        items(3) = "[Minimized]"

                        items(4) = "[Minimized]"

                    End If

                Else

                    items(3) = "[Error]"

                    items(4) = "[Error]"

                End If

                items(5) = p.MainWindowTitle

            Else

                items(2) = ""

                items(3) = ""

                items(4) = ""

                items(5) = ""

            End If
 

            ListView1.Items.Add(New ListViewItem(items))

Open in new window

If you want to know what controls are inside any Window, the you can use the GetWindow Win32 API function. With this function you can obtain all the hWnd of the child window of any parent window, and with recursivity, you can finally obtain all the hWnd contained in a Window and all of their contained sub-windows (i.e. controls).

For each hWnd you obtain, you can use GetClassName to get the class name of the window. With this data you can know if the window is a button, a slider, a listview, etc.

Hope that helps.

It is better to use EnumerateChildWindows.  It is possible for GetWindow can get into a state where it will go into an infinite loop.
