how to convert from dialog units to pixels?

Hullo, how are you doing guys??
I'm currently programming a simple card game UNO using C++ and Microsoft visual studio pro 2005.
I designed modeless dialog box to be my main window that the players are going to play on, but when it came to drawing some graphics, they were drawn in unwanted position on the main window, because the dialog designer gave me the coords in dialog units, but the functions used to draw use pixels. So can any one tell me a way of how to change my project properties, or the modeless dialog it self so it uses pixels??

thank you in advance
