Declaring arrays.

[Delta01]

Hey,

I'm kind of new to arrays and I'm trying to declare it at the start of my script so that my Case statement wont error out. I get errors like telling me it's exceeded the variables subscript. How do I declare arrays like $Hello[1] so that if I have a case statement like Case $Hello[1] = "Yes" I won't get an error if $Hello[1] wasn't been set.

I've checked the helpfile...

Learn the functionality of ReDim/UBound or cheat and use _ArrayAdd Edited April 10, 2008 by SmOke_N

No. That's not what I need.

My code is similar to...

Dim $Command[2]

;Create GUI

While 1
    ;Declare a few variables
    For $i = 1 To $Command[2]
    Next
    sleep(100)
    WEnd

Try running that, that's the error I get and that's what I'm trying to fix. Sorry, I wasn't very clear.

You're wrong.

That Is what you needed.

For $i = 1 To Ubound($Command) - 1

Unless $Command[2] = an integer.

Also keep in mind, you cannot exceed the limit you propose.

[2] < is the max, Arrays start at 0 (zero), so 0 and 1 are the only two elements you can use without exceeding the array elements.

Edit:

Example:

Dim $Command[2]

2 is the Max elements I can use.

[0] = 1st Element

[1] = 2nd Element

[2] = 3rd Element = Exceeding element size

Sorry and thank you.

Sorry for the double post...

Thanks for fixing the array error, but now it won't read what I want it to. Below is an example in notepad (type some text into notepad, ie Hello*Test and it should read the Test.)

Dim $ReadCommand[5]
Dim $Command[5]
$Title = "Untitled - Notepad"
$Text = ControlGetText($Title, "", "Edit1")
$Command = StringSplit($Text, "*")
    For $i = 1 To Ubound($Command, 2) - 1
        $ReadCommand = StringSplit($Command[2], @CR)
    Next
MsgBox(64, "Text read after the *", $ReadCommand[1])

1. Ubound($Command, 2) << You are referencing a 2 dimensional array but you only have a 1 dimensional array.

2. Why are you going to use a "loop" (For/Next) if you are hard coding the split with [2]?

3. http://www.autoitscript.com/forum/index.ph...st&p=295888 is the best I think I can help you now without referring (confusing you) with http://en.wikipedia.org/wiki/Array

Take a look at this -

No. No.

You are trying to read an array index that does not exist because AutoIt arrays are zero index. If you declare

Dim $var[2]

you are creating a two index array. This means you have indexes 0, 1. If you try to go out of this, you get a subscript error.
