build a variable name dynamicly

10 posts in this topic

All,

I'm new at this forum ans also to AutoIt, so don't shoot me when i'm asking something that's evident.

I'm looking for the correct way to build a variabele name.

i have a gui with 22 buttons. Every button has i'ts one settings.

depending on the input from an ini file, i need to set the focus on that button.

This is my code

ini file ==>

[buttonId]

button=15

code ==>

$ButtonId = IniRead("C:\Temp\myfile.ini", "ButtonId", "Button")

$button14=GuiCtrlCreateButton("test 14",130,410,100,50)

$button15=GuiCtrlCreateButton("Test 15",240,410,100,50)

$button16=GuiCtrlCreateButton("Test 16",350,410,100,50)

GUICtrlSetState($button & ButtonId, $GUI_FOCUS)

but the last line doesn't work :-(

kind regards

Probably its better to use an array.

the word $button is the start of my varable and indeed it needs to be $buttonId

what i want to accomplished is that i get "GUICtrlSetState($button15, $GUI_FOCUS)" this. but the 15 is comming from the $buttonid variable.

As mentioned by Cageman, you'd be better off using an array for all of your button variables instead of independent variable names.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Possible? Yes.

Practical? No.

$ButtonID = 15
$Button15 = 'It worked!'

MsgBox(0, "$Button" & $ButtonID, Execute("$Button" & $ButtonID))

You can use

GUICtrlSetState(eval("button" & ButtonId), $GUI_FOCUS)

Yep Eval can work too for this, but you still need the "$" for ButtonID:

eval("button" & $ButtonID)

That being said, using an array would be better than either Execute() or Eval() by a long shot, and will makes things less complicated.

There are only certain cases to use Eval, this isn't one of them I'm afraid.

Hi.

This might give you a start:

#include <GUIConstantsEx.au3>
#include <array.au3>

$ButtonCount=15
dim $aButtons[$ButtonCount+1][3]=[[$ButtonCount,"0=CtrlID,1=Buttonstate","2=ButtonText"]]

$h=30+$ButtonCount*30
$w=200
GUICreate("MyGui",$w,$h)
$aButtons[1][0]=GUICtrlCreateButton("Button #1",10,10,$w-20,25)
opt("guicoordmode",2) ; cell relative
$disabled=True
for $i=2 to $ButtonCount
    $aButtons[$i][2]="Button #" & $i
    $aButtons[$i][0]=GUICtrlCreateButton($aButtons[$i][2],-1,5) ; -1, 1 = next line
    if $disabled Then
        GUICtrlSetState($aButtons[$i][0],$GUI_DISABLE)
        $aButtons[$i][1]=$GUI_DISABLE
        $disabled=False
    Else
        $disabled=True
        $aButtons[$i][1]=$GUI_ENABLE
    EndIf
Next

GUISetState()

_ArrayDisplay($aButtons)

Regards, Rudi.
