CS_CLASSDC top-level constant

int const CS_CLASSDC

Allocates one device context to be shared by all windows in the class. Because window classes are process specific, it is possible for multiple threads of an application to create a window of the same class. It is also possible for the threads to attempt to use the device context simultaneously. When this happens, the system allows only one thread to successfully finish its drawing operation.

Implementation

const CS_CLASSDC = 0x0040;
