CDC dc;

...

HDC hdc = dc.GetSafeHdc();

or

HDC hdc = dc.m_hDC;

right i'm calling an outside library function that require HDC as a parameter. i think the code you gave me is correct, but when i call the function with hdc be the parameter, after complied, it give me unresolve external symbol. the outside function i called want a traditional window HDC but i gave MFC hdc, are they compatible.

The unresolve external symbol has nothing to do with HDC. There must be other problems. HDC is a handle of device context. Only given an HDC, you cannot tell whether it is from MFC or not.
