hello i have three bmp files one is static while other two are dynamically changing by a graphic object i have two threads for this purpose to update that two bmp files the problem is i want to display the static bmp as it is every time and the dynamic bmps updated every time may ma XOR a good solution but i don't know how to do this efficiently
i also need some code example for XOR to understand how to do it efficiently, i have done it in unsafe mode by XORing the two graphic matrices but it is very much expensive
help required.
thanx in advance
