I have a few large (~600k lines of code) Delphi projects. They include some custom components which our team has developed. Often, when I call up code completion with ctrl+space or just by pressing ".", the IDE locks up and thinks really hard for a long time. Sometimes the delay can be a full minute, or more. Other times, it pops up ...
I've had a major annoyance with the Borland/Codegear C++ Builder IDE for some time now. When I code I always use a standard layout for the code files. I have a standard header that I use, including, ie. the Licens of the file, filename, date, etc. But I haven't been able to find anywhere to insert this, so that when I - for instance - c...

Before Delphi 2006 (I think) introduced the TFlowPanel and TGridPanel, I did a control that was similar in concept. It still does a couple of things those controls do not do, and when upgrading my code to Delphi 2009, I decided to add a couple of enhancements to that as well. Right now, the order of the child controls is determined by t...

I'm getting ready to release a tool that is only effective with regular hard drives, not SSD (solid state drive). In fact, it shouldn't be used with SSD's because it will result in a lot of read/writes with no real effectiveness. Anyone knows of a way of detecting if a given drive is solid-state? ...
