Declare two API
-----------------------
<System.Runtime.InteropServices.DllImport("user32.dll")> _
        Shared Function GetWindowText(ByVal hWnd As IntPtr, ByVal txt As System.Text.StringBuilder, ByVal cnt As Integer) As     <System.Runtime.InteropServices.DllImport("user32.dll")> _
        Shared Function GetForegroundWindow() As IntPtr
    End Function

Use this codes
-----------------
        Dim hwnd As IntPtr = GetForegroundWindow()
        Dim sbuild As New System.Text.StringBuilder(255)
 
       GetWindowText(hwnd, sbuild, 255)

        MsgBox(sbuild.ToString)

Private Declare Function GetActiveWindow Lib "user32" () As Integer
 Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Integer, ByVal lpString As String, ByVal cch As Integer) As Integer
 Private Declare Function GetForegroundWindow Lib "user32" () As Integer


 Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Dim foreground_hwnd As Integer
        Dim txt As String
        Dim length As Long

        foreground_hwnd = GetForegroundWindow()

        txt = Space$(1024)
        length = GetWindowText(foreground_hwnd, txt, Len(txt))
        txt = txt.Substring(0, length)
        lb.Text = txt
        lb.Refresh()
