SUMMARY ======= The Mfccdc sample demonstrates how to set the Mapmode, Viewport, and Window parameters, and draws a rectangle based on given logical coordinates; then, the sample calculates the resulting device units. The sample shows how to use the following functions: SetMapMode() SetWindowExt() SetViewportExt() SetWindowOrg() SetViewportOrg() LPtoDP() NormalizeRect() MORE INFORMATION ================ The following files are available for download from the Microsoft Download Center: Visual C++ 6.0: The following file is available for download from the Microsoft Download Center: DownloadDownload Mfccdc.exe now (http://download.microsoft.com/download/vc60pro/Sample7/1/NT4/EN-US/Mfccdc.exe) For additional information about how to download Microsoft Support files, click the following article number to view the article in the Microsoft Knowledge Base: Q119591 How to Obtain Microsoft Support Files from Online Services Microsoft scanned this file for viruses.
