How to release HDC ?

[uus99]

I have a function that performs some drawing according to the bitdepth of the screen. The function is called in a loop continuously. The problem is, after a while it crashes. I have narrowed it down the problem to the HDC not being released. How can i release it? void Plot() { //Obtain current screen depth HDC hdc = ::GetDC(NULL); int screendepth=GetDeviceCaps(hdc, BITSPIXEL); //do something here according to the current bitdepth //how to release here? }

From the MSDN documentation on the GetDC function

After painting with a common DC, the ReleaseDC function must be called to release the DC. Class and private DCs do
not have to be released. ReleaseDC must be called from the same thread that called GetDC. The number of DCs is
limited only by available memory.
