Form losing focus stops counter

[woklet]

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer = 1
For i = 1 To 100000
Me.Label1.Text = Str(i) & " of 100000"
Me.Refresh()
Next
End Sub

When I click my Button1 and then click on another window, say Windows Explorer or Outlook, etc., my VB.NET form obviously loses focus. When I come back to it it doesn't refresh until the loop is completed.

Is there anyway to either keep the VB.NET form modal; not just within my VB.NET app but throughout all of the windows that are up on my PC?

Or is there a way to keep it running in the background or refresh it upon activating? I've tried the activated event, but it still waits for the for loop to finish.

Any thoughts? Thanks

To make your form respond to other events while doing heavy jobs, you can use Application.DoEvents() Method.

So your early code can be fixed to the below given form

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer = 1
For i = 1 To 100000
Application.DoEvents()
Me.Label1.Text = Str(i) & " of 100000"
Me.Refresh()
Next

End Sub

Hope that solves your prob

Another way is to put your loop on it's own thread.
