switch ... case <value>, <value>

6 posts in this topic

According to the help file I'm to use Switch like this:

Switch <exp[b][/b]ression>
    Case <value> [To <value>] [,<value> [To <value>] ...]
        statement1
        ...
    [Case <value> [To <value>] [,<value> [To <value>] ...]
        statement2
        ...]
    [Case Else
        statementN
        ...]
EndSwitchoÝ÷ Ù8b²×¬µÊzÈhÂËajÙ¢Æ)àéz»Û-®)à²)ÂjÇ¡ë'¢Úek*.¶X¤yìiyË^u«­¢+Ù

This is my result running the code (NOTICE how TestSwitch("FOO") fails):

>"Z:\scite\..\autoit3tools\AutoIt3Wrapper\AutoIt3Wrapper.exe" /run /beta /ErrorStdOut /in "Z:\Code\autoit\au3\foo.au3" /autoit3dir "Z:\scite\..\autoit-v3.1.1.126" /UserParams  
>Running AU3Check   params:  from:Z:\autoit3tools\au3check\
+>AU3Check ended.rc:0
>Running:(3.1.1.126):Z:\scite\..\autoit-v3.1.1.126\autoit3.exe "Z:\Code\autoit\au3\foo.au3" 
@AutoItVersion:=3.1.1.126
$ret:=
$ret:=
$ret:=
$ret:=TEST
+>AutoIT3.exe ended.rc:0
>Exit code: 0   Time: 3.938

Did I misunderstand Switch usage or have I done anything else wrong?

HI,

does it generally work with letters??? (No mix, just letters)

I thought, it will only work with digits.

I have reached the same conclusion. The confusing thing is that "" and 0 is evaluated equally. But I think that is a feature of the language.

Thanks.

try converting the test to a string for the comparison otherwise you'll have all kinds of problems

ConsoleWrite("@AutoItVersion:=" & @AutoItVersion & @LF)
TestSwitch("")
TestSwitch(0)
TestSwitch("FOO")
TestSwitch(1)
TestSwitch(2)
exit
func TestSwitch($msg)
   Local $ret
   Switch String($msg)
        Case "0", ""
            $ret = "Empty"
        case "1", "TEST"
            $ret = "TEST"
        case "2", "FOO"
            $ret = "FOO"
      case Else
            $ret = "UNKNOW"
   EndSwitch
   ConsoleWrite('$ret:=' & $ret & @LF)
EndFunc

I read the help file as "Value".... thus, "foo" has a value of 0

here is how i would handle the sictch

ConsoleWrite("@AutoItVersion:=" & @AutoItVersion & @LF)
TestSwitch("")
TestSwitch(0)
TestSwitch("FOO")
TestSwitch(1)
TestSwitch(7)
TestSwitch(11)
TestSwitch("Not there")
Exit
Func TestSwitch($msg = "")
    Local $ret
    
    Select
        Case $msg == ""
            $ret = "NADA"
        Case $msg == "FOO"
            $ret = "TEST-1"
        Case $msg == 0 Or $msg > 0
            Switch $msg
                Case 0
                    $ret = "No Value"
                Case 1
                    $ret = "TEST-2"
                Case 2,3,4,5 to 10
                    $ret = "FOO Number"
                Case Else
                    $ret = "UNKNOW"
            EndSwitch
        Case Else
            MsgBox(0, "", "No preceding case was true!")
    EndSelect
    
    ConsoleWrite('$ret:=' & $ret & @LF)
EndFunc  ;==>TestSwitch

OK, I'm satisfied :D

Thanks to @gafrost for showing that you can use strings in the test parameter as long as they are all strings. I could swear I had used strings before so I got really puzzled when my mixed thing did not work out.

Thanks to @valuater for providing a mixed sample using Select for strings and Switch for numeric parameters.

Thanks to all of you
