First thing you need to know is what are you processing? General you do a progress bar based on TotalItems vs. ItemsCurrentlyProcessed.

For example lets process a the rows in a DataSet.

pgBar.Maximum = dsData.Tables(0).Rows.Count - 1
pgBar.Minimum = 0
For RowCnt as Integer = 0 to dsData.Tables(0).Rows.Count - 1
'Process something here
pgBar.Value = RowCnt
Next

Or

For RowCnt as Integer = 0 to dsData.Tables(0).Rows.Count - 1
' Process something here
pgBar.Value = Cint(100 * (RowCnt + 1) / dsData.Tables(0).Rows.Count)
Next

The following link is to a custom progress bar direct from MSDN from scratch. But if this is for your class I suggest you only use it as reference material. Your teachers are bound to have seen it before.

How to create a smooth ProgressBar in Visual Basic .NET or in Visual Basic 2005

Here's code for my timer:

   Private Const PROGRESSBAR_MIN As Integer = 1
   Private Const PROGRESSBAR_MAX As Integer = 90

    Private Sub PaperTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PaperTimer.Tick
        PaperProgressBar.Visible = True
        If PaperProgressBar.Value >= PROGRESSBAR_MAX Then
            PaperProgressBar.Value = PROGRESSBAR_MIN
        Else
            PaperProgressBar.Value += 1
       End If
    End Sub

...as long as the timer is firing, the progress bar continues to count. You will have to figure out when the timer starts and stops.
