Hey guys,

I need to find a way to, based on a file's extension, determine what application to open up.


I know all that data is there in Windows somewhere (probably in the Registry somewhere), since I know if I double-click on a XLS file, it magically knows to open MS Excel.


But my program needs to do that - where can I find that data, so that, for example, if I look for the file type DOC, I find: "C:\Program Files\Microsoft Office\OFFICE11\WINWORD.EXE" or at least something similar that I can work with?

You can use the Windows API ShellExecute() function to start the application associated with a given document extension without knowing the name of the associated application.
