In order to use a ProgressBar you have to know the total number of rows before you start. If you don't know this before you start you will have no way of knowing where you are in the transfer. The following code assumes you have 142 rows. Every time you add a new row you increment the value of the ProgressBar by one. The line with the Sleep is only there to slow things down so you can see the ProgressBar moving.

Dim numRows As Integer = 142

ProgressBar1.Maximum = numRows
ProgressBar1.Value = 0

For i As Integer = 1 To numRows
    ProgressBar1.Value += 1
    System.Threading.Thread.Sleep(50)
Next
