The End of Windows XP

As we posted in September of last year, Microsoft announced that Windows XP, which was released 12 years ago, will no longer be supported after April 8, 2014. Our information tells us that only 3% of Xojo users are using Xojo on Windows XP. Supporting XP is limiting our ability to move Xojo forward on the Windows platform. Therefore, starting with Xojo 2014r1, we will no longer support Windows XP for the IDE itself.

Building for Windows/Linux on Newer Macs

We have discovered what we believe to be a bug in OS X Mavericks specifically on newer Macs. Apple started using Intel’s new Haswell processor in the MacBook Air in June, the iMac in September and the MacBook Pro in October. When you build for either Windows or Linux from OS X, any images you dragged into your project are converted to BMP format. The bug we discovered (which we have reported to Apple – RADAR case 15546907) results in a banding of the converted graphic.

Writing High-DPI Aware Windows Apps

Today’s laptops and monitors support high resolution displays which allow you to pack more information and content on the screen. Although one common complaint is that people find the text to be too small at the maximum resolution, Windows’ solution to this is the ability for the user to adjust the DPI setting.

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.

GUEST POST: Testing a Windows Service Application with Xojo

When working with Windows services you’ll want to debug the application while it’s running as a service. To do this, you can Select Run Paused from the project menu, then create the windows service and start it. Now you’re debugging your app while it runs in service mode.

All of this takes time, and having to create/start the service each time slows down debugging considerably.

I have written a little utility that allows me to right click on the debug executable and automate the service creation and startup. You can download this utility from https://dl.dropboxusercontent.com/u/18858366/DebugService.zip. The source for the Xojo project is included. The utility accepts the executable path as its argument, creates a service “_test” and starts the service.
