When I add a button (right mouse, add button) to a ttoolbar and resize it,
all the other buttons resize also. Is this a known problem or is there a
magic property on the toolbar I need to set to stop this spectacularly
useless behaviour. This is all design time, Win98 2ed, D5 PRO (latest sp).

That's the toolbars normal behaviour with a ttoolbutton. For unique button
sizes try using tspeedbuttons instead

Thanks. I can see now that VB does the same thing and that the menus I am
used to looking at are probably coolbars.

Hi guys, finally getting back to my combo/listview component problem (sigh,
I hate jumping between jobs at times)...
Anyway, I've attached the component source, although I'm not sure if the
list will accept the message with it... Anyway, once the listview has been
clicked on, nothing else

Hi Max, thanks for the pointers, if I use a TSpeedButton inside the
droppanel, it works fine, but if I use a TEdit, or TButton, I get the

I haven't used them yet. And if it is used for automatic garbage
cleaning (I think I'm right here) then it may not be a good
programming practice, or it may be a lazy way of programming.

You can get around the auto garbage collection easily enough. Neven's

which is a big advantage.

Not really. The main issue is designing your classes so that you can
actually take advantage of interfaces, rather than deep inheritance.

No. Delphi interfaces are actually implemented as pointers to a part

Does anyone know how to pass a value ( not a field in the update table) into

You can also delegate the inplemenation of an interface in delphi
So in your case ClassC inherits from ClassA and implements InterfaceB
(defined alongside ClassB)
ClassC has a subject of Class B which it delegates its implementation of
InterfaceB to
ie
TClassC - class(TClassA,

A trigger is internal (fired by an event on the table) so what do you

If you mean stored procedure then I think you will find an example in the

parameter, with Param[0] set its value.

Prefix your table with the name of the table owner, eg.
select * from [dbo].[sometable]

Luke,
Here's a component I've used for this:
type
TTabEdit = class(TEdit)
private
FAcceptTabs:Boolean;
procedure WMGetDlgCode(var message: TMessage); message WM_GETDLGCODE;
public
property AcceptTabs : Boolean read FAcceptTabs write FAcceptTabs;
end; { TTabEdit }
