[RESOLVED] How do you find the Install Path/Location of the EXE?

[steamruler]

I want to create a button that opens a supplied word document in their standard word handler like office or openoffice. But how do you find the Location of the exe (Or its folder) and using it to open the Word Document.

I have tried to use

Function GetFilenameOnly(ByVal Fullpath As String) As String
    Return System.IO.Path.GetFileNameWithoutExtention(FullPath)
End Function

with no use. Please help!
