Ever been unable to find that document you need for your next meeting?
Have you lost focus while working on one thing because you can’t stop thinking about something else? Feeling overwhelmed? There are several types of clutter: physical, technology, and mental. And that clutter is likely affecting you negatively.

Comments closedMost of the time, the access to our databases tables involves a small amount of columns (fields), so the use of the Field method of the RecordSet class is the most practical approach to retrieve the selected columns values. But what can we do when the query returns, for example, dozens of columns we need to get values from?
I’ve spent most of my career developing custom software. I’ve worked as an in-house developer creating custom “line of business” solutions. I’ve worked for software development firms that provide custom software for clients. And I’ve primarily been a self-employed custom software developer since first going out on my own in early 2000. Today, a lot of the work that I’m doing involves developing custom software solutions using Xojo.
I’m often asked by other developers – some who are already using Xojo and some who are not – where the opportunities for Xojo developers are, and how to find them. I also occasionally see these types of questions posted on the Xojo forum by developers who want to use their knowledge of and passion for Xojo to start their own business. So I thought I’d share some of my experiences and observations.
Comments closedMost Xojo Cloud users have already switched to the newer Xojo Cloud servers. These new servers have more RAM and SSDs and are the priced lower or the same as our previous servers. But moving your projects from one server to another is easier said than done. You’ll need to plan carefully to avoid downtime. Here is a simple change you can make to your DNS settings in order to limit downtime, making the move to a better server smoother.
Comments closedJSON (JavaScript Object Notation) is a great text-based data format that can be used for files and web services data communication.
The structure is simpler than XML which makes it much smaller and since it does not make use of all the tags you’ll find in XML, it is also significantly easier to read. However, if you open unformatted JSON in a text editor you’ll probably find it a bit dense. Here’s how to get around that.
Comments closedIn binary the high bit (the one immediately following the &b in Xojo code) is the “sign bit”. When it’s set to 1, the value is interpreted as “negative” and when it’s set to 0, the value is “positive”. Meaning that bit is not used as part of the “number” itself.
Comments closedCode doesn’t care whether you are new to programming or an old pro, a citizen developer or the head of engineering, some missteps can catch any of us. Read on to learn some of the most common programming pitfalls and how to avoid them.
Comments closedXML can sometimes be a bit confusing, so here are some tips to help you work with XML files.
First, you need to make sure your XML is really XML.
Comments closedWhen you add a control such as a PushButton to a Window (or a WebButton to a WebPage or an iOSButton to an iOSView), an instance of the control is created for you and added to the layout. Code that is in the event handlers of a control added in this way can refer to both its own properties and methods as well as the properties and methods of the window.
