IF question

[michaelslamet]

This look so noob and seems so inefficent:

If $avar = "" OR $another_var = "" OR $c1 = "" OR $d_var = "" OR $e_var = "" OR $another_var_again = "" OR $another_var_again2 = "" then
   ....
EndIf

 

Is there another way to write that If with many OR like above?

[jaberwacky]

Here's how I would do it, one way among many really.

Not really inefficient I think.

 

If Not $avar              OR _
   Not $another_var       OR _
   Not $c1                OR _
   Not $d_var             OR _
   Not $e_var             OR _
   Not $another_var_again OR _
   Not $another_var_again2 then
   ....
EndIf

lookit how pritty

Not as pretty, as jabberwocky6669's code, but it should work the same:

$a = 0
$b = 1

Switch ""
    Case $a
        MsgBox(0, "", "Not $a")
    Case $b
        MsgBox(0, "", "Not $b")
EndSwitch

$avar = 'a'
$another_var = 'b'
$c1 = 'c'
$d_var = 'd'
$e_var = 'e'
$another_var_again = 'f'
$another_var_again2 = ''
Switch ''
    Case $avar, $another_var, $c1, $d_var, $e_var, $another_var_again, $another_var_again2
        MsgBox(0, '', 'It is an empty string, zero, false or anything else that is nothing')
EndSwitch

If you want to check for an empty string then you may need to use == in the 1st post

[michaelslamet]

Aha, what is different between "=" and "==" ? Because I never use "==" before.

I'm open this thread because I remember I see it somewhere that (guiness??) write something like:

OR ($avar, $another_var, $cl, $d_var, $e_var, $another_var_again, $another_var_again2)

but I'm not remember about it and what is for

[jaberwacky]

It's in the Operators section of the helpfile.

Look at the help file AutoIt -> Language Reference -> Operaters

unofficially:

= will check the value. i.e. is it something, is it nothing, is it a numerical comparison etc.

== will check whether this string equals that string with case sensing. Like a contents check rather then a value check. If you check for "" then it will be true only if it is "".
