And here's another oddity in VBScript. You can use parens if you use the
Call statement. So either of the following lines would work.
Call Mouse.Click(0, 1)
Mouse.Click 0, 1

Thanks Doug and vic,
That does it, all though it's a fussy little line of code as if you don't include a space
between Click and 0 VBScript flags the error "object doesn't support this property
or method."
Warm regards.

You have encountered what I regard as
a rather confusing point in
VBScript syntax.
When calling a function and assigning its result to
something, you
parenthesize the function's arguments:
x = myFunc(1,2,3)
But when you call a sub, you don't use parens:
mySub 1, 2, 3
Now it just so happens that a single-argument sub call will
accept
parens anyway:
mySub(1)
and
mySub 1
do pretty much the same thing.
Well almost...
Putting parens around a single argument forces it to be
passed by
value rather than by reference. So
mySub(x)
passes x by value, whereas
mySub x
can pass x by reference.
This confuses people though, because you can see mySub(x) in
someone's
code, assume that means parens are acceptable, try mySub(x,
y), and
find out there's a hole in that logic. mySub(x), (y) would
work,
pointless though that probably is for most applications.

Hi all,
I am trying to perform a single left mouse button click, so
I open notepad, move the mouse to the "I" in file menu, open
the immediate mode app, and issue the following line of
VBScript:
Mouse.Click(0, 1)
I get the following error cannot use parenthesis when
calling a sub. What's wrong with the line of code above.
When looking at the mouse object Click method there are
parentheses in the method's break down.
Warm regards.
