get default program name

[Nico]

Hi all,
Is there a way in C# to know which program will be launched when I do:
Process.Start(new ProcessStartInfo(@"C:\video\test.avi"));
thanks in advance for your help.

Hello Nico,

By registry, see nodes' names in HKEY_CLASSES_ROOT

Instead of manually searching the Registry, you can also call the
FindExecutable Win32 API.
