Hi
I have a camera and making some process on frames.But I must make this process faster.
Because of that I'm trying to create a buffer.When I'm taking the new frame a thread will do the process on the old frame.How can I do that using threads? I tried CriticalSection functions but I've got run time errors.And I tried waitForSingleObject functions but I couldn't get more speed.What must I use ?

With threads you may have a performance gain just on multicore systems.
In any case mutithreaded programming is a quite complex topic and you should know what are you doing in order to get benefits (your issues with synchronization functions, make me think you need a deeper understanding of the matter).

my camera takes a frame at 15 ms.my processes on the images takes 30 ms.I want to create a buffer and taking the images to te buffer.
the scenario:
The main loop takes the images and writes them to the buffer.
the thread function takes them from the buffer and process the images.

You can create a thread for each buffer. If you need the processing result - wait for the appropriate thread.
