figuring out chars in a string (parsing)

figuring out chars in a string (parsing)

• Eric Bickle - BlueRealm

  I was unaware of that method.. I like it very much. I think I will revert to this solution. Thanks!

  I'd suggest something like this:

   

  OpenFileDialog1.ShowDialog()     'This is arbitrary, I used it to test the code
  
  Dim FileString As String = OpenFileDialog1.FileName
  Dim Length As Integer = 0
  Dim Index As Integer = 0
  Dim IsDesktop As Boolean = False
  
  'Loop to find the position of the last directory identifier "\"
  Do Until Index = -1
       Index = FileString.IndexOf("\")
       FileString = FileString.Substring(Index + 1)
       Length += Index + 1
  Loop
  
  'This gets the string that is just the directory (everything up to the last "\")
  FileString = OpenFileDialog1.FileName.Substring(0, Length - 1)
  
  'Here is where you run the comparison
  IsDesktop = My.Computer.FileSystem.SpecialDirectories.Desktop.Equals(FileString, System.StringComparison.CurrentCultureIgnoreCase)

  This is helpful but not exactly what I was looking for in my situation. I ended up using the following solution. I appreciate your help!

  Dim newstring As String = pathoffolder.Substring(pathoffolder.Length - 7)

  if newstring = "Desktop" then

  exit sub

  end if

  Well the pathoffolder isnt an object, it is a string. For example

  dim pathoffolder = "C:\Documents and Settings\user\my documents"

  Dim newstring As String = pathoffolder.Substring(pathoffolder.Length - 7)

  'newstring will return a value of "cuments"

  Make sense

  Although the code may work for your scenerio, you should use the .Net methods provided for you to find the directory name of a path:

  Dim MyPath As String = "C:\DataDrive\Graphics"

  Dim di As New DirectoryInfo(MyPath)

  If di.Name = "Graphics" Then

  MessageBox.Show(di.FullName)

  End If

  the "Name" method of the DirectoryInfo class will return the directory name....fullname returns the full path

  I'm not sure exactly how that works, but I'd love to know exactly what the "pathoffolder" object you're using is.
