While running my .NET application on Windows XP, randomly i get following exception - System.OutOfMemoryException: Failed to create a bitmap compatible with the screen to get information about screen bitmap format.
at System.Windows.Forms.DibGraphicsBufferManager.bFillBitmapInfo(IntPtr hdc, IntPtr hpal, BITMAPINFO_FLAT& pbmi)

Can anyone tell me why this error fires?

Your application is not clearing the RAM and is eating it up till you run out.

You can either rewrite the program to use far less RAM or clear it more often, or add more RAM id this is only being used on 1 computer.

Things like this are signs of bad coding practises but with anything written in .Net you really can not expect much better.
