c# - Get standard application for txt files (.NET) -


possible duplicate:
finding default application opening particular file type on windows

hello, in application want open text file, has no .txt extension. there way standard application .txt files in .net (c#)? sure use "notepad", there might people (like me), prefer (their standard) editor.

thank much.

edit:

the registry key "[hkey_classes_root]\txtfile\shell\open\command" references notepad, that's not standard app txt files. how current standard app .txt?

the absolute best option use shellexecuteex, passing see_mask_classname flag, open file if ".txt". method support things dde-based , drag-and-drop-based file opening mechanisms.

but if want (e.g. running partial trust , can't p/invoke shellexecuteex), here's how:

there's level of indirection. first have lookup

hkcr\.txt

read default value out of key, call txtkey.

then check

hkcr\ txtkey \shell\open\command

there's function you: assocquerystring
