VB2008 => VB.NET.

Moved to VB.NET

That's a simple one, it's saying that numcourses hasn't been declared. Show us where you've declared this variable.

Also, you're using VB.NET now, stop using MsgBox and start using the MessageBox Class. MsgBox is a legacy items left over from the VB6 days

have you declared numcourses as integer

Dim numcourses is Integer

i suggest you learn basic of vb.net

You might mean as.
so be a little nicer

anyway, yeah, I still catch myself using msgbox

I see you declaring k and temp, where are you declaring numcourses?

[code]Dim k As Integer
Dim temp As String
ReDim Preserve students(arraysize).courses(numcourses)
If numcourses = 0 Then
'redim students(arraysize).courses(0)
ListBox1.Items.Clear()
End If
students(arraysize).first = UCase(TextBox1.Text)
students(arraysize).last = UCase(TextBox2.Text)
students(arraysize).semester = UCase(TextBox3.Text)
students(arraysize).HSgradyear = UCase(TextBox4.Text)
students(arraysize).IDnumber = UCase(TextBox5.Text)
students(arraysize).courses(numcourses).coursenumber = UCase(TextBox6.Text)
students(arraysize).courses(numcourses).instructor = UCase(TextBox7.Text)

temp = Str(numcourses + 1) & ") " & students(arraysize).courses(numcourses).coursenumber & " " & students(arraysize).courses(numcourses).instructor
'ListBox1.Items.Add("ID#: " & "" & students(arraysize).IDnumber)
ListBox1.Items.Add(temp)
numcourses = numcourses + 1
'TextBox1.Text = ""
'TextBox2.Text = ""
'TextBox3.Text = ""
'TextBox4.Text = ""
'TextBox5.Text = ""
TextBox6.Text = ""
TextBox7.Text = ""
TextBox7.Focus()[code]

see your declaring k as an integer and temp as a string but you don't appear to be declaring numcourses as anything before you use it
