Context Menu Extension Handler
This code sample is named CTXMenu. It demonstrates how to implement a context menu extension handler. The application extends the File Explorer context menu that appears when you tap and hold a file.
Run "guidgen.exe" to generate a new GUID.
Copy this GUID to "guids.h", replacing the one that is already there.
Navigate to the solution file (*.sln), and double-click it. By default, the solution file is copied to the following folder:
C:\Program Files\Windows Mobile 6.5.3 DTK\Samples\PocketPC\CPP\win32\ctxmenu
Microsoft Visual Studio launches and loads the solution.
Build the solution (Ctrl+Shift+B).
Deploy the solution (F5). ctxmenu.dll is registered. built, and deployed to the folder
Launch File Explorer on the mobile device.
Tap and hold on any .BMP file to bring up the context menu. You should see an additional menu item.
The filename is retrieved from File Explorer via the IDataObject:IUnknown interface.
Context menu extensions are only loaded when a single file is selected; if multiple files are selected and the user invokes the context menu, File Explorer will not load any extension handlers.
