Change the default Open With
- by emptyheaded
How can I change the program a file is opened with by default (or at least add that program in the list of programs from Open With... ) using C# or VB.NET ?
What I mean is, I would like to have programs with the extension abc open by default by the program abc.exe. Or, have the program abc.exe in the list of programs that will be shown in the context menu on the "Open With" option, for files with extension "xls".
