yes, it's throwing me exception.

I've implemented the sample application from this site only...

sample code is:

try{
//get the graph filter ready to render
OpenFileDialog ofg = new OpenFileDialog();
if (ofg.ShowDialog() == DialogResult.OK)
{
String fileName;
fileName = ofg.FileName;
graphBuilder.RenderFile(fileName);
Text = fileName;
//set the trackbar
isSeeking = (graphBuilder.CanSeekForward() == -1) &&
(graphBuilder.CanSeekBackward() == -1);
if (isSeeking)
trackBar1.Enabled = true;
else
trackBar1.Enabled = false;
trackBar1.Minimum = 0;
trackBar1.Maximum = (int)(graphBuilder.Duration * 100.0);

Text = fileName;

//prepare and set the video window
videoWin = graphBuilder as IVideoWindow;
videoWin.Owner = (int)panel1.Handle;
videoWin.WindowStyle = WS_CHILD | WS_CLIPSIBLINGS | WS_CLIPCHILDREN;
Rectangle rc = panel1.ClientRectangle;
videoWin.SetWindowPosition(0, 0, rc.Right, rc.Bottom);
mediaEvt.SetNotifyWindow((int)this.Handle, WM_GRAPHNOTIFY, 0);

//set the different values for controls
trackBar1.Value = 0;

minutes = (int)graphBuilder.Duration / 60;
seconds = (int)graphBuilder.Duration % 60;
statusBar1.Panels[0].Text = "Duration: " + minutes.ToString("D2")
+ ":m" + seconds.ToString("D2") + ":s";
graphState = State.Playing;

//start the playback
mediaCtrl.Run();
}
}
catch( Exception ) { Text = "Error loading file"; }

What i had done is as follows:
Create a user control.
i have written all the above code in this class.
and then created an object of this usercontrol in another form.
and called the Run method from that form.
it works perfect.

Thanks & Regards,
Pramod

Microsoft released an object which allows you to burn data to cd. I gues it's named XpBurn or something..

Open txt2 in a streamreader object and open txt1 in a streamwriter object (setting the append argument to 'true')

txt1.Write(txt2.ReadToEnd());
txt1.Close();
txt2.Close();

txt1.Dispose();
txt2.Dispose();
