Getting the path of an opened file

Question

I'm working on a program that is associated with a file type ".gif" and whenever i open an .gif image anywhere on the PC, it would get the path of the file and set it as Picturebox.imageLocation

I've been Googling for the answer and i can't seem to find correct words to find it. I've seen few videos and they use preset location, so that doesn't help me much.

Do you have the ".gif" file association already set up? If not, see Associating file extensions with a program

Once you have that part done, you should have something in the registry like this:

HKEY_CURRENT_USER\Software\Classes\yourcorpname.yourappname.v1\shell\open\command", null, @"c:\path\to\app.exe \"%1\""

When the file is opened the %1 is replaced with the path of the file. You just need to make a Main method that has parameters:

Sub Main(ByVal cmdArgs() As String)
    MsgBox("The Main procedure is starting the application.")
    Dim returnValue As Integer = 0
    ' See if there are any arguments.
    If cmdArgs.Length > 0 Then
        Dim pathToGifFile As String = cmdArgs(0)
        ' Now you have the path to the picture to add to the PictureBox
    End If
    ' Insert call to appropriate starting place in your code.
    MsgBox("The application is terminating.")
End Sub
