shell default application to open a file

[craig_phillips2]

how do you shell a document instead of an application so that it opens with the default application for openiong files of that filetype. Basically what i a trying to do is shell a word document so it loads word or wordperfect. I cant be arsed to mess about with the registry anymore.

Const SW_SHOWNORMAL = 1
Private Sub Form_Load()
    ShellExecute Me.hwnd, vbNullString, _
