I've seen this done 2 different ways.
You could either set the ProgressBar.Maximum to: 100, or  to QuantityToLoad. 
example:
Option Strict On
Option Explicit On
Option Infer Off
Public Class Form1
Dim QuantityToLoad As Integer = 100000
Dim increment As Double = 100 / QuantityToLoad
Private Sub btnExample1_Click(sender As Object, e As EventArgs) Handles btnExample1.Click
ProgressBar1.Value = 0
ProgressBar1.Maximum = 100
ProgressBar2.Value = 0
ProgressBar2.Maximum = QuantityToLoad
For i As Integer = 1 To QuantityToLoad
'Some code
'Some code
'Some code
'Done loading item
ProgressBar1.Value = CInt(i * increment)
ProgressBar2.Increment(1)
Label1.Text = ProgressBar1.Value.ToString & "% complete."
Label2.Text = CStr(Math.Round((ProgressBar2.Value / ProgressBar2.Maximum) * 100, 2)) & "% complete."
Application.DoEvents()
Next
MsgBox("done")
End Sub
End Class
