Sometime ago a Xojo user asked if it is possible to use Xojo Web to create the kind of animated menus seen in several regular websites. After some investigation (and the invaluable help of Greg O’Lone), the answer is: yes, you can do that! If you are interested in seeing how to achieve this, continue reading!

There was a curious question on the forums about what # meant.
And from the way it was asked I could see the asker was thinking “I know what If means but what about that # in front of it?” And that if they knew what the # meant that the entire thing would make more sense.
And that’s a fair thought – except for one problem. The # by itself doesn’t “mean” anything. It isn’t like *, ^, + or – in that sense. It’s not an operator.
A reader asked me to clarify something about my previous post. Their question was:
When MyMethod is written as:Sub MyMethod( i() as integer ) i = array(10,20,30) system.debuglog CurrentMethodName + " i(0) = " + str(i(0)) + " i(1) = " + str(i(1)) + " i(2) = " + str(i(2)) End Sub
What happens if instead of trying to assign a new array you just alter the values in the array passed in?
Let’s talk about the difference between a “reference type” and the BYREF modifier on a passed parameter.
Here’s your first reminder: On January 14, 2020 Microsoft is ending support for Windows 7. We went through this a while ago when Windows XP reached end-of-life (no one really cared when Windows Vista reached end-of-life). Windows 7 was a very popular release as it was much better than Vista. It also didn’t help that Windows 8 was not liked at all with its many UI changes.
Did you know that it’s possible to load and use 3rd Party Frameworks in your Xojo iOS projects? There’s quite a number of good projects out there, many of which are on sites like GitHub and freely available for use in your projects. If you’re familiar with Declares in iOS, loading a 3rd Party framework requires just a couple of extra lines of code and a CopyFilesStep.
Last year at XDC 2018, Jérémie Leroy talked about making sure your screenshots mimicked the Apple method so that the date was always Jun 9th, the time was always 9:41 AM, the battery always shows as full and the WiFi strength always shows full. It got me thinking that it might be handy to be able to make the simulator always show those values when you do a debug run so that you don’t need to think about it when you are ready to start taking screenshots and movies of your app. One way to do that is to build & run project like SimulatorStatusMagic on the simulator before running your project, but it would be more useful if it was automatic.
The only built-in gesture for undo on iOS at the moment is to shake the device. This is not very intuitive to me and I’ve certainly done it by accident many times. The makers of Procreate chose a two-finger tap and have found that their users adapted to it nicely. This gesture is being adopted by more and more iOS developers. Here’s all the code you need to implement the two-finger tap for undo in your Xojo iOS apps.
If you are using SQLite you might be trying to share your database. What are your options when you want to be able to share your database?
GitHub just announced that private repositories are now free. GitHub has been a great source for Xojo open-source projects, so being able to also use it for private repositories is a nice bonus.
