I believe that GetSetProp and SetSetProp from TypInfo unit would allow to do this but I have no idea on to get it to work.

These days you see a lot of software displaying message windows in the right bottom corner of the active screen for a few seconds or until a close button is clicked (f.i. Norton does this after it has checked a download). I would like to do this using Delphi 7 (and if possible Delphi 2010, since I am slowly migrating my code to the late...

I'm looking for a way to control all business objects I create in my applications written in Delphi. As an article on Embarcadero's EDN (http://edn.embarcadero.com/article/28217) states, there are basically three ways to do this. I'm mostly interested in the last one, using interfaces. That way, when the business object is no longer bei...
I had some code before I moved to Unicode and Delphi 2009 that appended some text to a log file a line at a time: procedure AppendToLogFile(S: string); // this function adds our log line to our shared log file // Doing it this way allows Wordpad to open it at the same time. var F, C1 : dword; begin if LogFileName <> '' then begin ...
Hi, AFAIK the compiler does not generate RTTI if the type is not named. eg: T = array[0..1,0..1] of Integer; In this case it is possible to know the total size of the array, but it is impossible to know the size of each dimension. It works only if I use a type explicitly named: T01 = 0..1; T = array[T01,T01] of Integer; I missed somet...
