Hello I need some help. I'm trying to opening a file and sorting then displaying the results in a listbox. When I run the program I get the error "Index (zero based) must be greater thatn or equal to zero and less that the size of the argument list" Here is my code. I'm getting the error on the lstDisplay.items.add line. Thanks in advance for any help or suggestions offered.
Private fmtString As String = "{0,-50},{2,8},{3,8},{4,8},{5,8}"
Private Sub OpenFileDialog1_FileOk(sender As Object, e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk
Dim TextFile As String
Dim studentname As String
Textfile = OpenFileDialog1.FileName
Dim Student() As String = IO.File.ReadAllLines(TextFile)
Dim StudentQuery = From Line In Student
Let data = Line.Split(","c)
Let Lname = data(0)
Let Fname = data(1)
Let Grade1 = CInt(data(2))
Let Grade2 = CInt(data(3))
Let Grade3 = CInt(data(4))
Let Grade4 = CInt(data(5))
Order By Lname
Select Lname, Fname, Grade1, Grade2, Grade3, Grade4
For Each StuObj In StudentQuery
studentname = StuObj.Lname & ", " & StuObj.Fname
lstDisplay.Items.Add(String.Format(fmtString, studentname, StuObj.Grade1, StuObj.Grade2, StuObj.Grade3, StuObj.Grade4))
Next
End Sub
