In my application i need to create HBITMAP objects to which I render and from where I copy the result.
I use the function "CreateDIBSection" to create these bitmaps, however this function required a DC (Device Context) as first parameter. Currently I get this by calling GetDC(hWnd) on the main windows handle (hWnd). But I would like to be able to create HBITMAPS without the requirement of having an application window, without some kind of in memory DC, Is this possible?

A device context is a structure that defines a set of graphic objects and their associated attributes, as well as the graphic modes that affect output.
A device context is a Windows data structure containing information about the drawing attributes of a device such as a display or a printer. All drawing calls are made through a device-context object, which encapsulates the Windows APIs for drawing lines, shapes, and text.
CreateCompatibleDC(NULL) will create you a device context that is compatible with the screen - which sounds like it would be ideal in the situation.
