Displaying A Variable

[cppman]

I was'nt too sure how i would do this, so it here it goes:

Im trying to display a message box, with the VARIABLE NAME(not value) of what the user typed in...

like say they do this:

$MyVar = "MyString"

_ShowVar($MyVar)

how can i get what the VARIABLE NAME($MyVar) instead of the VALUE("MyString")

?????

$MyVar = "MyString"

msgbox('','', $MyVar)

MsgBox (0, "$MyVar", $MyVar)

[cppman]

I don't think u guys understood me completely.

sry if i did'nt make myself clear. I wanted to make the text in the message box actually say, "$WhateverTheVariableIs". not the value of that variable.

say they do. _ShowVar($Variable)

a message box will come up and say: "$Variable". not the value.

I put it in the title, so what. It is what you want.

But if you're doing a function that passes a variable, you're actually just passing the stuff in the variable, so it isn't going to work like that.

but then how would i use it for this, because u have it in quotes...

func _ShowVar($variable)

msgbox(0, "$variable", "")

EndFunc

_ShowVar($ThisIsAVariable)

it will always show, "$variable" in the message box, and not "$ThisIsAVaraible".

**ok, u beat me to it. lol

alright, thanks, thats what i was wondering.

is their any other way of doing something like that? without them having to type in the variable as a string?

CHRIS95219, maybe this: _ShowVar(String($MyVar))

edit: woops, ignore.

that'll display the value of that variable. thanks though.

nvm... lol, i got beat again. u edited while i was still posting.....

Can I ask why you'd need this?

Just thought (duh...) why not just put the var is quotes when you send it to the function. That way you're passing a literal string - the name of the variable.

[gamerman2360]

if you really needed to:

$MyVar = 2
MsgBox(0, "Example", _ShowVar($MyVar, @ScriptLineNumber))


Func _ShowVar($MyVar, $ScriptLineNumber)
    $i = 0
    While 1
        $i += 1
        If Not IsDeclared("_ShowVarVar" & $ScriptLineNumber & ":" & $i) Then
            Assign("_ShowVarVar" & $ScriptLineNumber & ":" & $i, "", 2)
            $case = $i
            ExitLoop
        EndIf
    WEnd
    $file = FileRead(@ScriptFullPath)
    If StringReplace($file, @CRLF, "") <> $file Then
        $delimiter = @CRLF
    ElseIf StringReplace($file, @CR, "") <> $file Then
        $delimiter = @CR
    Else
        $delimiter = @LF
    EndIf
    $filearray = StringSplit($file, $delimiter, 1)
    $linearray = StringSplit($filearray[$ScriptLineNumber], "_ShowVar(", 1)
    $readvar = StringLeft($linearray[$case + 1], StringInStr($linearray[$case + 1], ",") - 1)
    If Not ($MyVar == Eval(StringTrimLeft($readvar, 1))) Then SetError(1)
    Return $readvar
EndFunc

Edit: Only works when not compiled

Edit2: Needed to trim the $ off $readvar in order to eval it

I really don't think there is a reason to ever use this.

Exactly... seems like if you're the one making the script, and you have access to all the variables, that you could just do like my first post and get the job done. I really don't see what's wrong with a simple: MsgBox (0, "$MyVar", $MyVar)....

I can think of one reason, but it isn't very ethical...

Care to elaborate?

Even if you weren't making the script, say it was generated automatically, you could still have the var wrapped in quotes.

Well, when I first saw the question, the first thing I thought of was why not just use an array...

Edited the remainder, don't want to give anyone any ideas

I think the original poster was lost too....

I don't know how many right answers he needs, but this many seems like enough.

Global $MyVar
If Assign("MyVar", "$MyVar") Then MsgBox(4096, "$MyVar", $MyVar)

I think the point here, is he doesn't know what the Var is going to be, otherwise... why would you need to know the name, you already do... But I could be way off...
