Re: [DUG]: [Q] Using Format Function.....

[Nello Sestini]

I would like to use the good old format function: function Format(const Format: string; const Args: array of const): string; Easy when you have say Format('%s blah %s', [SomeVar1, SomeVar2]); However I have a situation where the format string is dynamic and so is the number of paramaters for the Args paramater. ie In one call I may have a format string with 12 %s and another 2 for example. Assuming that all the arguments that would be passed for Args are strings is there any way to build the args paramater dynamically. I tried a dynamic array but that did not seem to do the trick. Has anyone got any pointers or can someone tell me how to do this easily another way perhaps? the "array of const" that is the second parameter to Format is really an array of TVarRecs   so how about:     procedure TForm1.Button1Click(Sender: TObject); var     args: array of TVarRec;     alen:integer;       procedure addString(s:string);     begin         alen:=alen+1;         setlength(args,alen);         with args[alen-1]         do begin             VType := vtPChar;             VPChar := PChar(s);         end;     end;         begin     alen:=0;        addString('Donovan');     addString('what you');     addString('mind');     ShowMessage (format('%s is this %s had in %s?',args)); end;     -ns
