Can anyone tell me how i can get around this problem or better still if there is an easier way of deleting IEs history Please Help, Simon North This site may b ...Show All

• Visual C# Help with C# Screencapture --> avi

  Hello, I was exploring the possibility of creating a multi threaded screencapture program, that exports the onscreen content to an avi file in real time. I have looked around the MSDN help areas and cannot seem to find the information I need, such as how to capture the screen's image and put that into video format or capture the audio from either the stereo output, or mic. From the information I did find I am guessing that I will need to employ the threading and AVIfile classes. Any help would be great, thanks. you need to some how capture it to a video format - how is this done no idea, probably using the DirectX approach.

Right click the toolbar, Choose Items, COM components tab, select "Microsoft Chart Control 6.0". Stay away from the EditCopy() method, it causes an AccessViolation exception. ...Show All
