How do you start the default Windows Mobile applications like Calendar, Contacts or Messaging from your application? I recently came across this question in the Visual Studio Smart Device Development - Native C++ Project (quite a long name, huh?) MSDN forum. The answer is quite simple and relies on a registry entry that has been around at least since Windows Mobile 2003:
Here you find a list of varying size containing all the default applications in your machine (both a human-readable name and the required command line). For instance, on my HTC Touch Pro the calendar is stored in the following entry:
The application's human-readable name is stored in the "0" (zero) key while the command line is stored in the "1" key. If you look up this in your device's registry you will probably find something like:
Note that this requires further expansion by looking up the following entry:
The value of the "1" key contains "poutlook.exe" so the final command line to start the Calendar application must be "poutlook.exe calendar". Easy huh?
