The expression 'if not $foobar == ""' doesn't work as I expect...

Recommended Posts

Try this code:

$foobar = "sometext"
if not $foobar == "" then msgbox(0,"","one")
if not $foobar = "" then msgbox(0,"","two")

I expected to get "one" and "two".

Why not? why not "one"?

Hi,

As far as I know, the operator == is for matching the content exactly because there is some simplifications made by autoit (e.g : empty string = zero).

I think the operator == can not be used with the operator Not. The tricky way would to check the var type (e.g: IsNumber, IsString, ...)

Here is an example :

Global $iNumber = 0

If $iNumber == "" Then MsgBox(0, "", "exact empty string")
If $iNumber = "" Then MsgBox(0, "", "empty string or zero")

Br, FireFox.

Enclose in brackets e.g.

Local $sFooBar = 'sometext'
If Not ($sFooBar == '') Then MsgBox(0, '', 'one') ; Or use <>
If Not ($sFooBar = '') Then MsgBox(0, '', 'two')

The operator precedence is described here.

That's why you need brackets.

Oh, thanks guys!

I thought that the "NOT" operator had the same "operator precedence" of AND OR and didn't know that "==" matches "" and null while "=" matches "0" too.
