ListBox question

ListBox question

• Vjy

  Sorry - let me explain more ...

  I have a text file that I load into a list box. The text in the list box is 2 lines per per file entry - that is a file name then the next line is the location of the file "G:\directory\directory\" or what ever the associated file location is. This is repeated over and over.

  What I want to do is show the file name then the line below to be a button or somehthing so that when you click it either the file will pop up or just the directory - which is I think the best

  Some code that I have. nothing fancy - just part of what I am doing

  Dim sr As IO.StreamReader = IO.File.OpenText(LOADLOCATION)

  ListBox1.Items.Clear()

  Do While sr.Peek <> -1

  name = sr.ReadLine

  ListBox1.Items.Add(name)

  Loop

  sr.Close()

   

  OUT PUT NOW LOOKS like this

  filename1

  location1

  filename2

  location2....

   

  I would like

  filename [button for location]

  or

  [hperlink]filename[end of hyperlink]

   

  this is in a listbox

  You wil have to be a little more clear on whats going on and what you want to happen...

  Is the name of the file the first item in the list box and the directory the second item in the list box

  What do you want to happen (open Up) with the directory

  If Directory.Exists("ThePath") Then

  Dim MyFiles() As String = Directory.GetFiles("ThePath")

  For Each s As String In MyFiles

  Me.ListBox1.Items.Add(s)

  Next

  End If

  well loading it from a textfile will have a few problems:

• what happens if someone edits the entries or the lines dont match up

  however keeping it simple, if our format is:

  filename1

  location

  and we think that the format of the file and entries are the same then we could simply do this....

  Dim theReader as new System.IO.StreamReader("file.txt")

  while theReader.EndOfStream = false

  theReader.ReadLine() 'since firstline is "filename1" rather than the location which is the second line

  Me.theListBox.Items.Add(theReader.ReadLine())

  end while

  theReader.Close()

  then we implement a selectedindexchanged event on the listbox so when the user clicks on an entry, it fires the event and you can do whatever you want since the selected item has been changed....so in your example you wanted to launch the path of the item selected

  private sub theListBox_SelectedIndexChanged(byval sender a object, byval e as eventargs) handles theListBox.SelectedIndexChanged

  if Me.theListBox.SelectedIndex > -1 then

  System.Diagnostics.Process.Start(Me.theListBox.SelectedItem.ToString())

  end if

  end sub

  and thats it! alternatively you could combine the filename and location together....

  Dim theReader as new System.IO.StreamReader("file.txt")

  while theReader.EndOfStream = false

  Dim fullFileName as String = theReader.ReadLine()

  fullFileName = fullFileName & "\" & theReader.ReadLine()

  Me.theListBox.Items.Add(fullFileName)

  end while

  theReader.Close()

  does this help
