Extract path from path & filename

[Paul]

Hi,

Using the code below I can extract the filename from a path but I would like
to know how to get just the path too.
So if the full path is "C:\A Long Time Ago\In A Galaxy\Far Far
Away\SomeFilena me.txt"
The filename is: SomeFilename.tx t
The path only is: C:\A Long Time Ago\In A Galaxy\Far Far Away\

I know there's other methods of getting the filename only, path only etc.
that are new to VB.NET but they involve using the FileInfo/DirectoryInfo
classes and for this I prefer to use the InStrRev/Trim method.

Thanks,
Paul

Dim i As Integer
Dim sFilename As String
Dim file As String = "C:\A Long Time Ago\In A Galaxy\Far Far
Away\SomeFilena me.txt"

i = InStrRev(file.T rim, "\")
If i = 0 Then
'No path found, only filename
sFilename = file.Trim
Else
'Assign filename only to variable
sFilename = Right(file.Trim , Len(file.Trim) - i)
End If

MsgBox(sFilenam e)

Re: Extract path from path & filename

You can use virtually the same code...just change to use the MID function,
retunring the 1st character through the character before the first \ from
the end.

Re: Extract path from path &amp; filename

Paul,

For that is the path class.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemiopathmemberstopic.asp

I give you the member page the class page is for this in my opinion a little
bit confusing.

I hope this helps,

Cor

Re: Extract path from path &amp; filename

Or you could use the shared methods of the Path class
