Declaring variables at runtim
Is it possible to declare a variable at runtime ?
I want something like this :
procedure TForm1.SomeProc(Validated : Boolean);
begin
if Validated then
begin
strList : TStringList;
strList.Create(nil);
// Do some stuff...
strList.Free;
end;
end;

if Validated then
begin
strList : TStringList;
strList.Create(nil);
// Do some stuff...
strList.Free;
end;
end;
Who is Participating?
not possible,
except you've an inbuild-compiler
but why you want this,
why not easy
procedure TForm1.SomeProc(Validated : Boolean);
var strList : TStringList;
begin
if Validated then
begin
strList.Create(nil);
// Do some stuff...
strList.Free;
end;
end;
as you have to code the logic also
meikl ;-)

kretschmar, lucika: TStringList.Create not TStringList.Create(nil). TStringList is no component.
Shame on you ;-)

atleast, robert is right,
the creator of the tstringlist has no parameter,
but i've just copied the given code
shame on me :-))

Only a interpreted language can do that.
The above example does not need it.
strList is only a pointer. The object it points to IS created at runtime.
