Getting a Handle to a Device Context (Windows Embedded CE 6.0)
1/6/2010
Windows Embedded CE provides several methods for obtaining a device context handle, depending on whether the device is a display, printer, or memory device. For more information, see Obtaining a Display Device Context and Obtaining a Memory and Printer Device Context.
You use a display device context to draw in the client area of a screen. For more information, see Modifying a Device Context.
You use a memory device context to store bitmapped images in memory rather than sending it to an output device. A memory device context enables Windows Embedded CE to treat a portion of memory as a virtual device.
You use a printer device context to send output to a printer.
It is important when using a device context that you release or delete it when it is no longer in use. Releasing a device context frees the device for use by other applications.
Note
Failure to delete objects no longer in use can significantly affect performance.
