composing an variable with variables

[Jochem]

I have the following problem; I want to create an variable based on some elements (string, and some text but it is not working:

the variable I want to create = $Pic62g

GUICtrlSetState($Pic62g, $GUI_HIDE)

and i want to do it like this:

GUICtrlSetState("$pic" & StringTrimRight(_ArrayToString($own, @TAB, 1, 1), 0, 0, 0, 1) ,4) & "g", $GUI_HIDE)

the array to string is the name of computer WS-C62 I checked this with arraydisplay.

how can this be done, or is this impossible

Sure, but why is the $pic is quoted?

[Manjish]

anything u put in a "" can never be a variable name..

So as far as i know u can't do something like this.. if there exists a method it seems out of my scope and knowledge..

@Authenticity:

because it is a part of the final variable $pic doesn't exists. Finally it has to become $Pic62g. The first part ($pic) is static and the last part is static (g) and the part in the middle has to be generated...

It's called Eval... try it like this:

Dim $picWS_C62 = 'Text'
MsgBox(0x40, 'Title', Eval('pic' & Return_picWS_C62()))

Func Return_picWS_C62()
    Return 'WS_C62'
EndFunc

The functionality you're looking for is available in AutoIt. I don't have an example right at the moment, but the help file does. Look up the Assign function.

So, you almost need a function like VariableName = ("$pic" & StringTrimRight(_ArrayToString($own, @TAB, 1, 1), 0, 0, 0, 1) ,4) & "g")

I don't know of a way to do that. But, what if you use an array? If the two characters between "$Pic" and "g" are always going to be numbers, you could use them as your array index.

So: $n = StringTrimRight(_ArrayToString($own, @TAB, 1, 1), 0, 0, 0, 1) ,4)

GUICtrlSetState($Pic_g[$n], $GUI_HIDE)

Would something like that work?

But does this actually let you construct the variable name? The example shows:

Global $variable
If Assign("variable", "Hello") Then MsgBox(4096, "", $variable)   ; Will print "Hello"

But $variable is already declared. I don't think his $Pic62g can be declared until he finds the "62."

Jochem,

This will do what you want:

$Pic62g = "This is what I want!"

Global $array[2] = [0, "WS-C62"]

$res1 = _ArrayToString($array, @TAB, 1, 1)

ConsoleWrite($res1 & @CRLF)

$res2 = StringTrimLeft($res1, 4)

ConsoleWrite($res2 & @CRLF)

$res3 = "pic" & $res2 & "g"

ConsoleWrite($res3 & @CRLF)

MsgBox(0, "", Eval($res3))

; And then you can put them all together!
MsgBox(0, "", Eval("pic" & StringTrimLeft(_ArrayToString($array, @TAB, 1, 1), 4) & "g"))

Good tip: when you want to use lots of embedded functions, break them out into single steps until you are sure you have each part right. You had parameter errors in the StringTrimLeft function (and you cannot tell your left from your right!).

@Jochem

Did you get what you needed?

Thanks,

Jarvis

[Jochem]

thanks to all,

I indeed get what I wanted. After all I used the assign functions

But after all it is not the best way to build my script I think, so I have to find another way to make it.
