hi to all
the following source code used from Windows Media Encoder SDK to capture the screen But I have a problem with it.
I want to capture the every thing in the Screen such as screen of a movie player for example windows media player when it is playing a movie.
But when I capture a screen consist of a movie playing window then the Screen of movie player is bank in captured file.
How Can I capture the all screen consist of a movie player program such as windows media player correctly ?
My code is :
Imports WMEncoderLib
Imports WMPREVIEWLib
Imports System.IO
Public Class Form1
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub

Private components As System.ComponentModel.IContainer
