Whats the difference between SetFocus and SetFocus()?

[kazl]

Hi There

Forgive me for asking this but I am working with grids and have various places where I use SetFocus to move to a particular column control and also Refresh() the form.

In some places I have used Refresh and others Refresh()
or SetFocus / SetFocus().

What difference do the brackets () make?

Would these behave differently if I add or remove () ?

I can't seem to find any information on this, though I'm sure I've seen it somewhere.

PLEASE HELP......... been one of those weeks so far!

TIA, Kaz.

What difference do the brackets () make?

In reality, none.


By preference I always include () when referencing events, methods, functions or procedures because it makes the code much easier to follow.

I omitted to mention the obvious that if you are going to pass parameters, you will have to include () unless it's a procedure whereby the DO procedurename WITH params still works.

Kaz,

As Chris mentioned, if you are passing parameters, you need the parentheses.

You also need them if the method you are calling returns a result. For example, if you have a method called Test which returns .T. or .F., the following code will produce an error:

IF THIS.Test
* do something
ENDIF

but the following is OK:

IF THIS.Test()
* do something
ENDIF

Apart from those two cases, it won't make any difference. Some people always add the parens, as a matter of habit, whether they need it or not. Personally, I don't, but that's just me.

Hi

I wondered if the presence or absence of () was making my program misbehave. But it's just my grid code, too may things going on (as usual).

Thank you Chris and Mike for your replies.
