OK not the greatest title but this one is not too easy to put in a few words
i have a jpg file for example with a custom file extension of jjj for example
now i associate .jjj with my application so that when i click a .jjj file my application runs.
how do tell my application the filename and/or path of the .jjj file that opened it?
Was able to fine a way to do what i wanted the code in my app needed to be this
Dim args() As String = Environment.GetCommandLineArgs
If args.Length > 1 Then
args(0) = ""
Dim fileName As String = String.Join(" ", args).Trim
Dim fi As New System.IO.FileInfo(fileName)
If fi.Exists AndAlso fi.Extension.ToUpper = ".JJJ" Then
in order for me to get the path and name of the file that started the app up
props where props are due this is not my code found it on experts-exchange written by Idle_Mind
