I'm in the middle of sorting out a nested set of if/then begin/end pairs, and missing the heck out of CodeRush's structural highlighting (which I used to have in Delphi 6, and loved). Is there a freeware IDE add-in out there that will accomplish the same for Delphi 2007? Note: I know Castalia does this as well. I tried Castalia a whil...

Hi, I wanted to document my source using doxygen + pas2dox. When I set everything up, including the filter and the extraction options (extract everything), doxygen runs fine.

I've written a grid control and would like to add support for the mouse wheel to it. I thought it would be as simple as overriding the DoMouseWheel virtual method, but there is a bit of a problem with it. You can set the number of lines to scroll at a time in Control Panel and the default there is three. And this makes perfect sense whe...
