Wanita muslimah payudara montok. Hi All, I am trying to show Dialog with a Progress Bar (Marquee Style) in a Background Worker. Everything goes well until somehow I got an error because the BackGround worker tried to start and it was busy, but I cannot duplicate the error, maybe you guys more experienced knows something I am doing wrong. I changed the Background Worker and Progress Bar properties in the Properties window of the Designer mode, so you won't see that stuff in my code. Thanks in advance! Code: Order is Before, Order2 is After. Public Class Order Private Sub AcceptOrder() Save() ' This method goes through the server in a synchronous call, so it blocks the UI until it returns also we will process a credit card payment, instead of blocking the UI, I want to show a 'Progress Bar' which I don't care the progress, because I don't know how many time will take to the user insert the card etc.

UPDATE: I can duplicate the issue when I left the credit card reader without inserting my card, after 5 minutes I get a 'Transaction Cancelled' error then I think something times out, and I start to get the error. The funny thing is that it doesn't happen when I am debugging, just in 'Production'.
