Hi all there

I am trying to capture frames from video captured by webcam.
I have applied skin detection algorithm on the captured images and draw rectangle around the face. Frames are captured by a timer tick event. everything is working but the following error comes.

"Attempted to read or write protected memory. This is often an indication that your memory is corrupt"

If i increase the interval of timer to 500 it gives this error after some time, but as i decrease the interval of timer to 250 it begins sending this error message frequently.
I am using Windows7 OS. Visual Studio 2008 .NET framework 3.5;

Thanks in advance

I think problem in your webcam. 250 and 500 it's a very small interval. When timer tics time after time, your webcam is still busy. Your application refer on unallocated memory. That is why this error comes :)

thanks for replying.
but i have checked it on 2 different computers, Problem is still there but it comes once or twice during programe execution but does'nt hurt programe execution. i have decreased the interval to 33 in timer (means 30 frames per second). Another thing how i will come to know that the application is refering to unallocated memory?
thanks in advance
