IF <> Multiple values??

[tes5884 2]

Is there a way to create an IF loop comparing multiple values in a single statement? Something like below.

IF $x <> "1" OR "2" OR "3" Then
    ConsoleWrite("Success")
EndIf

Thanks!

tes5884,

Use Switch:

$x = 6

Switch $x
    Case 1, 2, 3
        ConsoleWrite("Fail" & @CRLF)
    Case Else
        ConsoleWrite("Success" & @CRLF)
EndSwitch

All clear?

You can do it using If like

IF $x <> "1" OR $x <> "2" OR $x <> "3" Then     ConsoleWrite("Success")

On single line If you don't need EndIf

Also see _Iif()

you can nest them inside each other.

But for a lot of disparate values switch,as suggested, is better.

Edit: of course in the If example, using And makes more sense.. as in $x does not equal any of the values listed, rather than using Or.

Can't I write something like
 

if($mylongvariablenameOrExpression in ("h","m","s")) then something

?

@LoWang did you try it?

I tried and failed obviously. Why would I ask if it worked? ;-) There is a possibility I just use wrong syntax and there is a way to write it similar to this and that is why I ask

That is a good question; most wouldn't ask if they'd already answered their own question. The best practice way of doing this (as was pointed out just about exactly 5 years ago) is to use a Switch.

[LoWang 1]

I just wanted to make the code more compact because using switch would generate many lines. Some other languages allow a coder to use similar syntax, so I wondered if AutoIt knows it too. But maybe I found a compact way like this:

#include <Array.au3>
local $possibleChars[]=["h","m","s"]
$k=_ArraySearch($possibleChars,$myChar)  ;$k is not needed but must be there
if @error then msgbox(16,"ERROR","invalid char")

BTW I know this thread is old but I don't see a reason to fragment topics because some things don't change

I remember many years ago where number of lines in a program was important because each line was occupying memory space and memory space costed M$.  Today only thing left is efficiency.  How fast can you do a task. So instead of asking what is the least number of lines you can do something, you should verify how fast is one compare to the other.

OK, but I believe readability of a code is also important. If a relatively simple function is so long that it does not fit on a screen then it's harder to understand it (load it into a brain memory) and work on it especially if I revive old code or somebody else starts working on it.
Anyway I think both my question and example are clear, so there is no need to challenge it's validity ;-)

[JLogan3o13 1,724]

@LoWang you saved yourself 3 whole lines from doing it the way Melba suggested above, but in so doing you had to introduce an entire UDF. To each their own, but I doubt most people would count that as a big win

[LoWang 1]

ok that switch with comma separated values would be similar actually I see

Not really...

if($mylongvariablenameOrExpression in ("h","m","s")) then something

Does this mean :
if one of these chars  "h", "m", "s"  is present in $mylongvariablenameOrExpression  then something  ?

It's a quite different situation

.... with a little help from SQLite

#include <SQLite.au3>

; -- turn on the sql engine --------------------
Global Static $g__sSQliteDll = _SQLite_Startup()
; -- open a 'memory' DB --
Global Static $hDb = _SQLite_Open()
; ----------------------------------------------

If _IsInList(1, '2,3,4,5,6,7,8,9') Then
    MsgBox(0, '', 'there is')
Else
    MsgBox(0, '', 'there is not')
EndIf

Func _IsInList($Target, $List)
    Local $aMyResult, $iMyRows, $iMyColumns
    _SQLite_GetTable(-1, "SELECT " & $Target & " IN (" & $List & ");", $aMyResult, $iMyRows, $iMyColumns)
    Return 1 = $aMyResult[UBound($aMyResult) - 1]
EndFunc   ;==>_IsInList

_SQLite_Shutdown()

p.s. you have to save sqlite3.dll along with your script. take it from here if you do not have it yet -> https://www.sqlite.org/download.html (Precompiled Binaries for Windows session)

My question is the same; there are 1000 ways to skin the proverbial cat in AutoIt, we all know this. And everyone loves to demonstrate their own take on the different ways things can be done. But how is this approach better than the straightforward way presented by Melba several years ago, and how does it satisfy the user request of making the code more compact?

[Gianni 803]

nothing against other ways of doing things and not necessarily a better way, I simply love try/see/run across new techniques and approaches. looking for and trying new ways of doing old things sometime can open new perspectives, new stimuli     ..... sometime not.

This may be an older post but this is usually how I go upon really long if not statements. Seems pretty compact

$Animal = 'duck'
If StringInStr('cat,dog,fish',$Animal) = False Then
    Msgbox(0,'animal','Quack')
EndIf
