You can use the press-and-hold feature of a program key to create a new document. This process is similar to clicking Newon the Filemenu on a desktop computer.

To program a press-and-hold feature for a program key

  1. Call the SHGetAppKeyAssocfunction to determine the VK code of your application.

  2. Set a timer in your application to the amount of time you want a user to hold down the control. Generally, this should be no longer than one second.

  3. When the timer expires, call the Windows Embedded CE GetAsyncKeyStatefunction using the VK code received from SHGetAppKeyAssoc.

    If GetAsyncKeyStatereturns a VK_DOWNmessage, the program control was held the entire time.

For more information about VK mapping, consult the documentation for the device driver available from the manufacturer of your target device.
