array compare with variable

[daniel02]

Hi all,

I just started with all these scripting stuff but I am stuck at the moment. I want to comapre a static variable with an array in if --- endif

I want to compare all array values but I can not find what string is used for it. I knew it from ksh scripting where you can say to get all array values ${arr[*]}

$var1 = 1

Local $arr[3] = ["element 1", "element 2", "element 3"]

if $var1 = ${arr[*]} then

...

endif

So just compare if $var1 has the same value as one of the array values and if it is the same value do somethig.

Thanks a lot in advance

Daniel

If $var = $arr[1] then
MsgBox(0, "", "MATCH!")
EndIf

use double [

Local $arr[3] = [["element 1", "element 2", "element 3"]]

@JamesBrooks as far as I know I only compare array value1 with the variable and not every value in the array?

@Quizzy If i use double I think the whole expression is than one value.. But i need them seperated. Or am I wrong?

cheers

I do not want to do something like

If $var = $arr[1] OR $var = $arr[2] OR $var = $arr[3] then

What the hell Quizzy?

Daniel, if you want to check all variables do this:

Local $arr[4] = [3, "element 3", "element 2", "element 3"]
Local $var = 1

For $i = 0 to $arr[0]
    ConsoleWrite($arr[$i] & @CRLF)
    If StringInStr($arr[$i], String($var)) Then 
        MsgBox(0, "", "Match at: " & $arr[$i] & "!")
    Else
        ConsoleWrite("No match found with: " & $arr[$i] & @CRLF)
    EndIf
Next

I know you could use UBound() but I find it easier this way when using arrays which don't change size.

[daniel02]

Thanks a lot James. So there is no way to just Wildcard it with $arr[*]? I find this is very complicated but anyway understandable.

One more (and hopefully last) question:

What is "& @CRLF"

Thanks again

You could also use _ArraySearch and check for returnvalue >= 0.

"string" & @CRLF means:

& -> concatenate two strings

@CRLF -> Macro for Carriage return + Linefeed (the line separator chars for Windows)

Daniel, if you want to check all variables do this:

Local $arr[4] = [3, "element 3", "element 2", "element 3"]
Local $var = 1

For $i = 0 to $arr[0]
    ConsoleWrite($arr[$i] & @CRLF)
    If StringInStr($arr[$i], String($var)) Then 
        MsgBox(0, "", "Match at: " & $arr[$i] & "!")
    Else
        ConsoleWrite("No match found with: " & $arr[$i] & @CRLF)
    EndIf
Next

I know you could use UBound() but I find it easier this way when using arrays which don't change size.

Which is fine for this example, but it could easily be misunderstood by some that arrays are 'always' built with [0] element containing an updated value corresponding to the array's size. While most built in functions use that standard, not every array is built that way. Using UBound() is much safer, especially when giving instruction to a novice.... But that is just my pompous opinion Edited February 4, 2009 by SpookMeister

[daniel02]

@spookymeister so could you give me an examlpe how to solve my problem with ubound?

[James]

SpookMeister, that's why I mentioned when it's a fixed size. Sure, I should have put a note there explaining why.

[SpookMeister]

Using James' example...

Local $arr[4] = [3, "element 3", "element 2", "element 3"]
Local $var = 1

For $i = 0 to UBound($arr) - 1
    ConsoleWrite($arr[$i] & @CRLF)
    If StringInStr($arr[$i], String($var)) Then
        MsgBox(0, "", "Match at: " & $arr[$i] & "!")
    Else
        ConsoleWrite("No match found with: " & $arr[$i] & @CRLF)
    EndIf
Next

[edit] Fixed my screwed up example... sheesh... I need to wake up before interfacing with the world

Sorry if I came across as picking at you, I was mostly just being an ass (still drinking my first cup of coffee here)... no insult/disrespect was intended Edited February 4, 2009 by SpookMeister

Oh no problem, takes a lot for me to get offended these days

Nice example too, however when I tried it, it errored (my attempt) nevermind.

Oh, you forgot to remove the 3 from the array.

Local $arr[3] = ["element 3", "element 2", "element 3"]
Local $var = 1

For $i = 0 to UBound($arr) -1
    ConsoleWrite($arr[$i] & @CRLF)
    If StringInStr($arr[$i], String($var)) Then 
        MsgBox(0, "", "Match at: " & $arr[$i] & "!")
    Else
        ConsoleWrite("No match found with: " & $arr[$i] & @CRLF)
    EndIf
Next

use double [

Local $arr[3] = [["element 1", "element 2", "element 3"]]

That form of initialization would only be appropriate for a 2D array:

#include <Array.au3>; Only for _ArrayDisplay()

Local $arr[2][3] = [["element 1A", "element 1B", "element 1C"], ["element 2A", "element 2B", "element 2C"]]
_ArrayDisplay($arr, "$arr 2D array")
