Generate Dynamic Gui?

Go to solution Solved by Melba23,

Hi guys so I'm stuck mentally about how to design a GUI where the number of selections vary run to run.

I tried playing around with the code below but of course that's not going to generate unique variables so I can read those controls for responses.. The only thing I can think of is that the gui has to have everything predefined but hidden...Am I correct?  for example

$Label1, $Label2, $Label3, $Label4, $Label5, ....

$combo1, $combo2, $combo3...  

But thats going to get very tedious, is that the only way? I would generally expect the "$selectionList" to contain 20 or less variable.. 

Basically I need to re-created array display but with the ability for the user to select from a combo box.


;Expanding Gui Test

#include <ComboConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

Local $SelectionList[3] = ["element 1", "element 2", "element 3"]

#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 447, 464, 192, 124)

$LabelRRLog = GUICtrlCreateLabel("RR Log?", 352, 8, 47, 17)
$Combo1 = GUICtrlCreateCombo("Combo1", 352, 32, 81, 25, BitOR($CBS_DROPDOWN,$CBS_AUTOHSCROLL))

$LabelText = GUICtrlCreateLabel("Text#1", 16, 32, 324, 17)
For $i = 0 to UBound($SelectionList)
$Label3 = GUICtrlCreateLabel("Text#2", 16, (32 + ($i * 16)), 328, 25)
$Combo2 = GUICtrlCreateCombo("Combo2", 352, (32 + ($i * 16)) , 81, 25, BitOR($CBS_DROPDOWN,$CBS_AUTOHSCROLL))

#EndRegion ### END Koda GUI section ###

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE

Use an array to store the control IDs, not individual variables.

I an not quite sure what you are looking to do, but here is how you can deal with variable numbers of controls:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

#include <Array.au3>
#include <ComboConstants.au3>
#include <MsgBoxConstants.au3>

; Initial random count
$iCount = Random(1, 20, 1)

; Fill combo
Local $aSelectionList[20]
For $i = 0 To 19
    $aSelectionList[$i] = "Selection " & $i

; Arrays to hold CIDs
Global $aLabel[20], $aCombo[20]

; Create GUI
$hGUI = GUICreate("Form1", 500, 500)

$cLabelRRLog = GUICtrlCreateLabel("RR Log?", 300, 10, 50, 20)
$cCombo1 = GUICtrlCreateCombo("", 350, 10, 80, 25, BitOR($CBS_DROPDOWN,$CBS_AUTOHSCROLL))
GUICtrlSetData($cCombo1, _ArrayToString($aSelectionList))



While 1

    $iMsg = GUIGetMsg()
    Switch $iMsg
        Case $GUI_EVENT_CLOSE
        Case $cCombo1 ; Main combo selected - delete and redraw controls
            $iCount = Random(1, 20, 1) ; New count
        Case Else
            ; Look to see whic combo was activated
            For $i = 0 To $iCount - 1
                If $iMsg = $aCombo[$i] Then
                    MsgBox($MB_SYSTEMMODAL, "Combo activated", $i)


Func _DrawControls()
    For $i = 0 To $iCount - 1
        $aLabel[$i] = GUICtrlCreateLabel("Text#" & $i, 20, 35 + ($i * 25), 300, 20)
        $aCombo[$i] = GUICtrlCreateCombo("Combo#" & $i, 350, 35 + ($i * 25), 80, 25)

Func _DeleteControls()
    For $i = 0 To $iCount - 1

Actioning the main combo will change the number of other combos, actioning each of which results in a MsgBox.

If you can give a better description of exactly what you want, we can refine the script.

Jesus.. THIS is why I'll never be a real programmer. I would have spent hours writing out variable / control names instead of just realizing that the handle for the controls could be stored in an array itself. So simple, I feel dumb but also excited to try it. Thanks @jchd and @Melba23
