B4J Question FileBaseName & FileExtension

[Walt]

FileBaseName and FileExtension, found in the jMMTools library are just what I needed.
But, I'd like to know if there are any other slick ways the get the name and extension out of a file?

Try:

    Dim FullFilePath As String = "C:/users/file.ext"
    Dim FileName As String = File.GetName(FullFilePath)
    Dim Pos As Int = FileName.LastIndexOf(".")
    Dim FileBase As String =  FileName.SubString2(0,Pos)
    Dim FileExtn As String = FileName.SubString(Pos)
    Log(FileBase)
    Log(FileExtn)

You shouldn't assume that there is an extension. You need to check that Pos is not -1.

Dim FileBase, FileExtn As String
if Post = -1 Then
 FileBase = FileName
Else
 FileBase = FileName.SubString2(0,Pos)
 FileExtn = FileName.SubString(Pos)
End If

You shouldn't assume that there is an extension.

Actually, in my case, I can since I did a SetExtensionFilter.

Your code did clarify the routine for me though. I was a bit fuzzy on it before.

Thanks, I'll give it a try.
