Just to be clear, you are using MsgBox as a subroutine in Method 1 and as a
function in Method 2 (you are testing a value that is returned from the
MsgBox call)... when used as a function, parentheses are required, when used
as a subroutine, they are only mandatory when the Call keyword is used and a
mistake to use otherwise. Here is the reason why as I explained it in an old
posting of mine...

As others have shown without specifically pointing to the reason, your
problem stems from the parentheses. MsgBox is a function and when used to
return a value, such as like this...

Answer = MsgBox("Here is a question", vbYesNo Or vbQuestion)

the parentheses are required. When no value is returned, the function
effectively becomes a subroutine. There are two proper ways to call a
subroutine...

Call MsgBox("Here is a question", vbYesNo Or vbQuestion)

and

MsgBox "Here is a question", vbYesNo Or vbQuestion

Note that when Call is used, the parentheses are required; however, when the
Call keyword is omitted, the parentheses are syntactically incorrect. So you
are probably asking, "Why did it work when I didn't add the 2nd argument?"
Good question. It seems that when parentheses are used in a statement that
are not required by syntax, VB assumes it has an expression to evaluate and,
well, it attempts to evaluate the contents of the parentheses. When you
specified only a single text argument, VB could evaluate it... it simply
evaluates as itself. But, when you added the 2nd argument, VB has no
mechanism to evaluate two expressions without an operator of some kind
between them (the comma is not an expression operator), so it generated an
error. The bottom line is to use parentheses in a subroutine statement
**only** when they are required by syntax (do not use them to "pretty"
things up as doing that will create problems in more situations than the one
I just outlined).

...
you can

method 1
msgbox, "hello World",vbyesno,"my message"


method 2
if msgbox( "Continue?",vbyesno,"Program check")=vbNo THEN
///quit code
else
///continue code
end if

Ok, I see now. You can't use ()'s. Thanks.

yes

the syntax is

msgbox prompt, buttons, title

VBA intellisence gives you the full list, but basically, whatever you
use as
"title" will appear as the heading
