Assign and IsDeclared - Problem

[JohnBailey]

The below code is an example of what I'm trying to do (note: the random function is just there for this example). Why does it say the variable does not exist when the Assign passes?

For $i = 0 to 2
    If Not Assign('htmlCaptureTab'&$i,Random(0,50,1)) Then 
        MsgBox(0,'Var not created','At position '&$i)
    Else
        If IsDeclared(Eval('htmlCaptureTab'&$i)) Then
            ConsoleWrite('Variable Exists : '&'htmlCaptureTab'&$i &@LF)
        Else
            ConsoleWrite('Variable does NOT exist : '&'$htmlCaptureTab'&$i &@LF)
        EndIf
    EndIf
Next

Because you used Eval() in the wrong place:

For $i = 0 To 2
    If Not Assign('htmlCaptureTab' & $i, Random(0, 50, 1)) Then
        MsgBox(0, 'Var not created', 'At position ' & $i)
    Else
        If IsDeclared('htmlCaptureTab' & $i) Then
            ConsoleWrite('Variable Exists : ' & 'htmlCaptureTab' & $i & " = " & Eval('htmlCaptureTab' & $i) & @LF)
        Else
            ConsoleWrite('Variable does NOT exist : ' & '$htmlCaptureTab' & $i & " = " & Eval('htmlCaptureTab' & $i) & @LF)
        EndIf
    EndIf
Next

IsDeclared() wants the string name of the variable, not the contents of the variable.

P.S. This doesn't address the fact that Assign() and Eval() are evil, and you should be doing this with an array instead...

HAHA thank you PsaltyDS! I just discovered that about IsDelcared() - it needing a string name.

Good point about the array! :"> My actually code is MUCH longer and this was a VERY boiled down version. I was using Assign to store the variable id of a GUICtrl. However, as you said, I can do this with an array so THANK YOU and I'm a moron

I used the array and it's working great, but I do have a huge problem http://www.autoitscript.com/forum/index.php?showtopic=55355 - More than one ctrl is removed/deleted WEIRD!
