By "it does not matter" I implied that there is no compile error when MsgBox
has a single argument wrapped in round brackets and its return value is
neither assigned not sunk by CALL.

It does matter. If you enclose the argument to a Sub in
parentheses, VBA evaluates it to its actual value and passes it
ByVal instead of ByRef.

First, you should use the named constants i.e. vbOKOnly etc.,
instead of
numeric values as this makes your code more readable.

The problem is:

If you are not interested in what key users clicked, the
arguments of the
MsgBox function are NOT included in round brackets. If you have
included the
arguments in round brackets, the result is not transparently
sunk i.e you
need to assign the result to a variable e.g

resp = MsgBox("Message",vbOkOnly)

or use CALL, e.g

Call MsgBox("Message",vbOkOnly)

Strangely, if you have only a single argument within the round
brackets, it
does not matter whether you are using round brackets or not.

Hi Guys

Please help. I am obviously failing to understand something
very basic about
MsgBox syntax.
I have only previously used this function to give simple
messages to the
user, and provide a single (default) OK button: E.g.

MsgBox "Your time has expired"

I want to add more buttons in due course (Yes, No, etc) but,
for now, was
just trying to customise the title (caption) of the the
message box:

MsgBox ("Your time has expired",vbOKOnly,"Time expiry
notification")

produces a compile error ("expected: =") and I can't make
sense of the Help
associated.
I am not including any Help/Context, so have left those
options blank

I have tried assigning the message and Title as strings

Dim Msg As String
Dim Title As String
Msg = "Your time has expired"
Title = "Time expiry notification"
MsgBox (Msg, vbOKOnly, Title)

but to no avail..

And
MsgBox (Msg, vbOKOnly, Title, , ,) just produces another type
of 'expected'
compile error

Thanks, Phil

PS. Once I have sorted the syntax, I should be able to use 0
instead of
vbOKOnly, 1 for vbOKCancel, etc. Right?
