I've used the mstscax ActiveX control in a C# Winforms application in the past.
My PC connect to network by a WIFI router.
With my c# application, I click connect button, after 60s, show remote desktop. While using mstsc connect the same machine, it will show remote desktop as soon as possbile.
How can I fix the problem of 60s.
follow is part of my c# applicaton code
