Path Size with Multiple versions of Delphi

Category

I work on a variety of projects in several different versions of both Delphi and Visual Studio. A lot of these projects also include database access. To support all these different projects, a lot of different tools need to be installed and with each comes a set of paths that are setup for the applications to find libraries, support tools, and so forth. Since most software tools can also generate both 32-bit and 64-bit code these days, there are often two sets of paths for each type of compilation.

Preventing Multiple Application Instances in Delphi with TMutex

Category

Having worked in Delphi for many years, I've seen the development tool and it's RTL evolve significantly, yet remain resilient in backwards compatibility. Early on, to prevent your application from running multiple times, there were generally two different approaches:

  1. Search for the name of your app's main form by name, or
  2. Search for a "mutex" created by your app.

 

dbForge Data Generator for SQL Server

Category

DevArt Software has been busy at producing a great number of database tools and components for both Delphi and Visual Studio developers over the last few years. They're still coming out with new ones as well. One of the most recent additions is dbForge Data Generator for SQL Server. I purchased version 1.0 in April, 2015 and they've been hard at work improving and adding features--they're already at version 3.5! You can read about their features on their web site linked above, but I'd like to highlight a few I think are notable and have been very useful to me.

Linux, Lazarus, and Lots of scripting

A friend of mine runs a business selling a Windows application for a niche market. Of course he has a web site with lots of information and a way to download a trial of his software and then pay and register it. Since he's a technical person, likes writing code, likes to keep overhead low, and his needs are fairly simple, he wrote the registration program himself. He's most fluent in Delphi so it was natural to write the registration program in Delphi--an old, but very functional Delphi 2007.
