Solution 1

You have two ways to do it

1.

VB

dim FileNameOnly as string = io.path.getfilename(file_name)

Further reading : MSDN: Path.GetFileName method[^]

2.

VB

dim file_info as new IO.FileInfo(file_name)
messagebox.show(file_info.Name)

Further reading : MSDN: FileInfo Class[^]

personally I prefer option 1 as you dont have to create any additional objects for the job requirements.

post a code snippet when your adding them name to the list and we'll go from there

DiiR 30-Jan-12 10:36am

Dim index As Integer = file_name.IndexOf(".")
' i used the indexOf to determine the extension

Dim length As Integer = file_name.Length

extension = file_name.Substring(index)

If extension = ".avi" Then
LVVideo.Items.Add(file_name, 0) 'this is where the file is added to the listview

End If

http://msdn.microsoft.com/en-us/library/beth2052%28v=vs.90%29.aspx this is a great reference

I would replace the code with the following as it does the same but without string manipulation.

if IO.Path.GetExtension(file_name) = ".avi" then
LVVideo.Items.Add(IO.Path.GetFilename(file_name))
end if

"IO.Path.GetExtension(file_name)" will return the extension of the filename
"IO.Path.GetFileName(file_name)" returns the filename with its extension
