To Whom It May Concern
I am finalizing an application that uses .NET 1.1 and DirectX with a mpeg or avi movie displaying a video of a particular road and section. When I navigate to another road section the panel is not cleared unless another movie is selected. I have tried the dispose method without any luck. My current code is as follows:
// dispose of the old video to clean up resources if (video!=null){
video.Dispose();
//video = null;
//videoPanel.Refresh();videoPanel.Controls.Clear();
//videoPanel.Dispose(); //videoPanel.Update();}
// open a new videovideo =
new Video(file); // assign the win form control that will contain the videovideo.Owner = videoPanel;
// resize to fit in the panelvideoPanel.Width = width;
videoPanel.Height = height;
// play the first frame of the video so we can identify itvideo.Play();
video.Pause();
Could someone please advise me if there is another alternative. I am trying to finalize the software for release within the next week.

Clearing a Windows Forms panel containing a DirectX movie

You should just be able to reset the directX Device and not redraw to it.

//Clear the backbuffer to a blue color
device.Clear(ClearFlags.Target, System.Drawing.Color.Blue, 1.0f, 0);
The above line clears the device..

I attempted to clear the device the other day but it did not work. Which class & method contains the device.clear as a root method I am using Visual Studio 2003 for this job and neither the Panel or DirectX.Video class contained the clear method that was mentioned in the last post. Once again I will post the code that I am working on. It is as follows:
if (video!=null){
video.Dispose();
//video = null; //videoPanel.Refresh(); //videoPanel.Controls.Clear(); //videoPanel.Dispose(); //videoPanel.Update();videoPanel.ForeColor = System.Drawing.Color.Blue;
videoPanel.BackColor = System.Drawing.Color.Blue;
videoPanel.Refresh();
}

Unfortunately that is what I have been doing all along and it basically did not do what I required. I have been trying to use Dispose, Update, Refresh & setting the object to null with no avail.
