Class methods have been around since Delphi 2. Where have you been
all these years?
Not explicitly, as I said, you cannot for example call them on the
class, you call them on a nil instance
which is hardly elegant php for example you would call a class method by
TClass::Method()

I'll say it again: no you won't. ;-)
I'll clarify my posting for you.
If you tried what the original poster said (I'm using D2006), and
recreated it (i.e. create two forms, make the second one not
autocreated, add a method to the second form with a simple ShowMessage
in it, and call that method

You can call TShowOff.Static1() from way back in Delphi, if it is declared as

Hi,
Is there any way to limit maximum memory, which an delphi application can be
allocated by Windows 2000 or xp? In some pc I am seeing a delphi application
while running gets allocated till 94 mb (in task manager) and no more, where
as I don't see any such limitation in my pc,
thanks

Probably. ;-)
Which is why I clarified my original statement.
Cheers,

P.S. I've been doing Delphi dev on and off since Delphi 1, so I do
understand the difference between the cases where I do and don't have
code in a method referring to instance properties as opposed to just a
simple
If they did (share the same class var), I would regard that as a bug.
Can't say I've tried though.

In your case you were probably tricked by Delphi
(optimizer??)...
Yes, if you have just ShowMessage in your method
everything will be fine. But ... did you try to assign
value to some local variable? You will have AV cause
we don't have the object
Which leads me to another point, It would be nice (and maybe Delphi
does) have class variables reintroduced in subclasses ie
TSingleton = class
public
class var Instance;
end;
TSingletonA = class(TSingleton)
)
TSingletonB = class(TSingleton)
)
do a B 'share' Instance?
Watched one of Alistair Christie's online videos on form resizing. Great,

than one control at once by selecting several (and I thought that was only
to move them as a group - doh!)

On your forms set AutoSize to False and Scaled to True. This is the
default for versions above D2005 I think. Previously AutoSize = True
was the default.
You may have to change the widths of some controls that don't autosize

I hope you don't use interfaces or dynamic arrays then. Since they

Well actually its not 100% surprising, thing about modern languages with

I agree, the Delphi for PHP name just doesn't seem right to me - they
apparently had big debates about it at CodeGear. I guess they are just
using the Delphi name to give it more credibility. Has anyone written
anything significant yet in it? The only thing I've done is the

I'd be interested to know because in PHP 5+ that is exactly what happens
which means for a singleton
template you have to copy the class var into the subclass (or as I have
just considered) use an array
of class vars for any subclassing
