CWinApp::EnableShellOpen

Visual Studio 2012

Call this function, typically from your InitInstance override, to enable your application's users to open data files when they double-click the files from within the Windows File Manager.

Copy 
void EnableShellOpen( );

Call the RegisterShellFileTypes member function in conjunction with this function, or provide a .REG file with your application for manual registration of document types.

C++
Copy 
// The following code fragment is from CMyApp::InitInstance. 
// CMyApp is a CWinApp-derived class. 

// enable file manager drag/drop and DDE Execute open
EnableShellOpen();
RegisterShellFileTypes();
