Guest Post: Running Xojo Apps on Windows with Elevated UAC

We’d like to thank Wayne Golding for offering the following tip. Wayne Golding has been a Xojo developer since 2005. He operates an IT Company Axis Direct Ltd www.axisdirect.nz which primarily develops applications using Xojo that integrate with Xero www.xero.com.  Wayne’s hobby is robotics where he uses Xojo to build applications for his Pi2 often implementing IoT for remote control.

Do you need to run a Xojo Application on Windows with Elevated UAC? Here’s Wayne’s trick to achieve that goal.

Take advantage of your multi-core processor

Nearly all CPUs used by your devices, from computers to tablets to phones, now contain multiple CPU cores.

Faster Internet

I’ve discovered a way to potentially speed-up your Internet access. Before we get to that, it occurs to me that the way in which computers find each other on the Internet may be a bit of a mystery to many. If you’d like to understand how it all works read this first.

Your devices (computers, tablets and smartphones) are constantly accessing their assigned DNS server and since they often can’t continue until a response is received, the speed of your DNS server can have a big effect on the speed of your Internet access. If you’re using any of the Internet classes in Xojo, this will of course affect the performance of your apps as well. Not all DNS servers are created equal. You are probably using one at your Internet provider and it may not be the fastest DNS server available to you. But with all the DNS servers out there, how can you know which one is fastest?
