I don't understand exactly how your code works, but wglCreateContext must be called if any wglMakeCurrent call is to succeed. (You need an OpenGL context for the entire lifetime of the OpenGL window) ReleaseDC shouldn't be called until you are closing the window. Doing it before probably releases the glcontext as well, making wglMakeCurrent fail.
