Web Services Part II: Xojo Web, at your service

In a previous entry we started to dig into web services with Xojo. The first post focused on the backend (server side), creating the Xojo app acting as middleware between the clients and the database that holds your data. We are using SQLite as the backend engine but it would not be difficult to change to other supported database engines like PostgreSQL, MySQL (MariaDB), Oracle or SQL Server, and even ODBC; all of these are supported by Xojo!

Software Distribution Simplified with GuancheMOS

In an ideal world there is a person responsible for every step in software development, from coding, UI design, distribution, documentation, marketing and support. All of this can seem really overwhelming for independent developers and small businesses. But if you break it down and take it one piece at a time, it’s manageable by even the smallest team of one. Right now, let’s look at software distribution.

For software, distribution usually means generating and validating unique serial numbers for each of your products and users. Serial numbers (or license keys) help you manage your users, unlock a free trial or demo version for full use and, of course, minimize illegal use of your apps.

Create a Preferences Class with Operator_Lookup

Xojo is an Object Oriented Programming Language and, among other things, that means that it supports Methods Overloading. We have seen in other posts that some of these overloaded methods can be Class Constructors, but, there are others things you can do. For example, we can overload the operators. These are the methods in charge of adding two instances of the same class, subtracting, multiplying or dividing them. But we also have at our disposal another operator we can overload: Lookup. What advantages does this give us and how it does it work? Let’s explore it while building a Preferences class we can use in any of our projects.

PDF File Generation? There is an API for that!

I’ve heard it several times: how can I export to PDF from Xojo? Sure, there are lots of answers pointing to a bunch of resources, including excellent plug-ins from third parties. But can you accomplish the same thing using an already available API? Yes, there is a remote API for that! The requirement is that your Xojo app will need to have access to Internet … and, of course, you’ll need to do just a bit of coding.
