WMAPMODE implements a modeless dialog box that allows the user to dynamically change the mapping mode attributes for the device context of WMAPMODE's main window. These attributes are the mapping mode, window origin, window extents, viewport origin, and viewport extents. Changing these attributes changes the main window's logical coordinate system.
To illustrate the effects of changes to its logical coordinate system, WMAPMODE's main window displays:
- The current values for the mapping mode attributes.
- The dimensions of the client area (in both device units and logical units).
- The current mouse location (in both device units and logical units).
- A bitmap. A second modeless dialog box allows the user to specify where the bitmap is drawn.
For more information on using mapping mode attributes, please refer to the following two books:
- The "Microsoft Windows Software Development Kit Reference, Volume 1," Section 2.5, "Mapping Functions."
- "Programming Windows version 3" (Charles Petzold, Microsoft Press), Chapter 11: "An Introduction to GDI."
