Question

I long variable in vb.net which contains the following information,

Dim g As String = "$C:\Program Files\Cavaj Java Decompiler\cavaj.exe$C:\Users\Yoosuf\AppData\Local\Google\Chrome\Application\chrome.exe$C:\Program Files\DVD Maker\dvdmaker.exe$C:\Program Files\Adobe\Adobe Photoshop CS2\ImageReady.exe$C:\Program Files\Java\jre6\bin\javaws.exe$"

The $ symbol is used as a delimiter to separate each item from the other. I need to add the exe file name at the end of each path to a listbox. However the initial process of retrieving the variable to individual array elements is not working properly.

Dim strArr() As String = g.Split("$")  'This variable is empty
For count = 0 To strArr.Length - 1
Dim arr As String = strArr(count).Split("\")

Dim strval As String = ""
For i As Integer = 3 To arr.Length - 1
        strval = arr(i)
        Dim j As Integer = arr.Length - 1
        strval = arr(j)
        Dim result As String = strval.Substring(g.Length - 5)
        result = g.Substring(g.LastIndexOf("\") + 1)
        ListBox1.Items.Add(result)
 Next

Please refer to the code below and the associated comments. Also I have comment out some code which I feel is not required based on what you want to do.

Dim strArr() As String = g.Split("$")  'This variable is empty
        For count = 0 To strArr.Length - 1
            Dim arr() As String = strArr(count).Split("\") ' Split returns an array

            Dim strval As String = ""
            For i As Integer = 3 To arr.Length - 1
                'strval = arr(i)
                Dim j As Integer = arr.Length - 1
                strval = arr(j)
                'Dim result As String = strval.Substring(g.Length - 5)
                'result = g.Substring(g.LastIndexOf("\") + 1)
                ListBox1.Items.Add(strval)
            Next
        Next
