We're still thinking, but we'd like to move it to something like VS2010's docking and visual look: This has the following features: Shows a blended outline where the window will dock Docks into tabs, as well as side-...

I am converting a low level C library to Delphi. I find a lot of casts. I think it is normal in C World. I think I am safe in throwing them out. Integer is 32 bit only here. What do you think? What could be the overhead of OOP if I convert it to objects etc? Similarly I want to know the cost of try .. finally and exceptions. Give me ...
This is a spin off from my last question How does delphi convert ModalResult properties? Since Delphi doesn't convert ModalResult properties, what's the best way for me to convert ModalResult properties to integers?

I have noticed quite a few times that syntax errors like Exit(push(ASBDD(asPixmap, _ScriptSavePixmap(Script, PMRGBAdjust(_ScriptGetPixmap(Script, Args[0].Index), adjparams)))); actually compiles. Notice that one closing bracket ) is missing. (Of course it also compiles if I add this missing bracket!) Is this a documented feature? ...
Not sure what happened to Bold/Eco during the Borland/Codegear/Embarcadero transition but I sure miss it in the newer versions of Delphi. Anyone know of a framework that comes close? If not, maybe you could suggest a combination of libraries and components that comes close. ...
I've been reading about CrossKylix recently, but for most uses one has to consider 3rd party components. So I would like to know which of the actively developed components still support Kylix. Many added partial or complete Kylix support back in the day, but I'm affraid some never kept updating, and the IFDEF-ed parts that compile with ...
I've got some code that worked fine under Delphi 2007 but breaks under D2010. It involves passing in a string, converting it to a PWideChar (specifically, a WideString pointer, not a UnicodeString pointer), doing some processing, and then calling SysFreeString on it. It works fine until a blank string is passed in, then SysFreeString b...

I've got some long but simple loops in my Delphi program that may loop millions of times and take some seconds to execute. The code inside of the loop is very fast and has been optimized. It just takes long because it is done so many times. e.g.: Screen.Cursor = crHourGlass; R := FirstRecord; while R <> nil do begin { do something si...
