Hi DjangMan, In fact I could create a class etc. But I would like to try this without using objects, since it will be a constant and everything is already done, my only concern is about to using a data type which could store (pre-determined) array length of some type of data. Let's forget...

Hi Guys, I'm having some trouble when I'm trying to Initialize a constant record when one of the types is a "VARIANT" one. For example: This WORKS: const myRec : array [0..1] of record Num : integer; Str : string; end = ( (Num: 100; Str: 'ABC'), (Num: 200; Str: 'DEF') ); But...

Hi everybody, I'm having a little trouble to check if an object was already created. I tried some examples that I've found on google but without any lucky. Example: procedure TForm1.TestClick(Sender: TObject); var conn : TADOConnection; begin try if not Assigned(conn) then...

Prattaratt, I understood. Thank you very much.
