Why dont you use Form.ShowDialog in the loop. Stops execution of the loop and you can ask user whatever question you need.

Question
I'm having a bit of a problem figuring out how to pause a for...next loop to await user interaction. I'm comparing the hashes of different files in a for...next loop and if they are different, I want to pause the loop until the user decided which file to keep.
Here's my code, so i hope you see what I'm trying to do.
For i = 0 To ListBox1.Items.Count - 1
If GetCRC32(ListBox1.Items.Item(i)) = GetCRC32(ListBox2.Items.Item(i)) Then
log("same")
Else
Dim v1 As String = ListBox1.Items.Item(i)
Dim v2 As String = ListBox2.Items.Item(i)
Dim f1 As New FileInfo(v1)
Dim f2 As New FileInfo(v2)
Dim c As String
If f1.LastWriteTime > f2.LastWriteTime Then
c = v1
Else
c = v2
End If
RichTextBox1.Text = v1 & " and " & v2 & " seem to be different." & vbCrLf & _
"Last changed:" & c
End If
Next
The user-interaction is via two buttons, which I have no code for yet...
