Add element in a ComboBox if it's not in the ComboBox data

Recommended Posts

Good morning :)

I'm working on a little project, and I was wondering if there's a way ( sure there is ) to insert data to a ComboBox control everytime the user insert some text in the ComboBox which is not in the ComboBox data. I'll try to explain with an example:

- Form with some data ( ComboBox is empty );

- User prompt something in the ComboBox: if what the user prompts is not in the ComboBox values ( at the moment empty ), then insert the value in the ComboBox values, in order to have, next time the user prompts the form, the value that he entered.

More pratical example:

- First call of the form, ComboBox empty;

- I prompt "A" in the ComboBox;

- Second call, in the ComboBox I should see "A";

- I prompt "B" in the ComboBox;

- Third call, I should see "A"
                                           "B";

- And so on...

Everytime the form is called, I re-create it, so I think I can't use _GUICtrlComboBox_AddStrings().

I tried with

Global $strCboStrings = ""

; When the user prompt the form, the code below is executed.
; I.E. : User prompt "A", after the if I should have "A";
; In the second call, If I write "B", I should see "A"
;                                                  "B";
; If I write "A" again, in the combobox values should not be any changes.

If Not StringInStr($strCboStrings, GUICtrlRead($cboVoiceCategory)) <> 0 Then
    $strCboStrings &= $strCboStrings & "|" & GUICtrlRead($cboVoiceCategory)
EndIf

Any suggestion?

Thanks :)

FrancescoDiMuro,

I would do something like this:

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

; Create a Global variable to hold the combo data
Global $sComboData = ""
; Create placeholders for the child GUI and controls
Global $hChild = 9999, $cCombo = 9999, $cAdd = 9999

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

; You say you recreate the combo each time, so this will do just that
$cAction = GUICtrlCreateButton("Action", 10, 10, 80, 30)

GUISetState()

While 1

    $aMsg = GUIGetMsg(1)
    Switch $aMsg[1]
        Case $hGUI
            Switch $aMsg[0]
                Case $GUI_EVENT_CLOSE
                    Exit
                Case $cAction
                    ; Create a child GUI
                    _CreateChild()
            EndSwitch
        Case $hChild
            Switch $aMsg[0]
                Case $GUI_EVENT_CLOSE
                    ; Close the child GUI
                    GUIDelete($hChild)
                Case $cAdd
                    ; Add new data to the combo
                    _AddComboData()
                Case $cCombo
                    ; Just to show that the data is selectable
                    MsgBox($MB_SYSTEMMODAL, "Selected", GUICtrlRead($cCombo))
            EndSwitch
    EndSwitch

WEnd

Func _CreateChild()

    ; Create child GUI
    $hChild = GUICreate("Child", 250, 250, -1, -1, $GUI_SS_DEFAULT_GUI)
    ; Create combo and load with saved data
    $cCombo = GUICtrlCreateCombo("", 10, 10, 200, 20)
    GUICtrlSetData($cCombo, $sComboData)
    ; Create a button to add new data
    $cAdd = GUICtrlCreateButton("Add", 10, 50, 80, 30)

    GUISetState()

EndFunc

Func _AddComboData()

    ; Read the content of the combo edit
    $sComboSel = GUICtrlRead($cCombo)
    ; Check if in saved data
    If Not StringInStr($sComboData, "|" & $sComboSel) Then
        ; If not then add to saved data and load into the combo
        $sComboData &= "|" & $sComboSel
        GUICtrlSetData($cCombo, $sComboData)
    EndIf

EndFunc

Thanks for you help!

I was missing this part

$cCombo = GUICtrlCreateCombo("", 10, 10, 200, 20)
GUICtrlSetData($cCombo, $sComboData) ; ---------------------------> This one!

Thanks a lot!

Have a good day :)

      Hello Forum, 
      I have one special Combo-box [with BitOR($CBS_DROPDOWNLIST, $GUI_SS_DEFAULT_COMBO, $CBS_SIMPLE) ] and if I press one button I want to change the Combo-box's background color, and after I press Button B I want to change it to the basic settings and it not works.
      I wanna do this with one combo-box.
      I have already tried several methods and I tried  GUICtrlComboSetColors that I have found on this forum.
      (But this methods works perfectly with Cobo boxes that don't have BitOR($CBS_DROPDOWNLIST, $GUI_SS_DEFAULT_COMBO, $CBS_SIMPLE). 
      Here is the example code
      #include <ButtonConstants.au3> #include <ComboConstants.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #Region ### START Koda GUI section ### Form= ;$CBS_DROPDOWNLIST ;$GUI_SS_DEFAULT_COMBO $Form1 = GUICreate("Form1", 504, 249, 252, 227) $Combo1 = GUICtrlCreateCombo("", 136, 24, 193, 25,BitOR($CBS_DROPDOWNLIST, $GUI_SS_DEFAULT_COMBO, $CBS_SIMPLE)) ; I want to change this special combo's background color if I press button 1 $Button1 = GUICtrlCreateButton("Button1", 112, 96, 75, 25) $Button2 = GUICtrlCreateButton("Button2", 264, 96, 75, 25) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### GUICtrlSetData($Combo1," " & "|" & "apple" & "|" & "banana" & "|" & "cherry" ," ") While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $Button1 GUICtrlSetBkColor($Combo1,0x0078D7) Case $Button2 ;Makes the original bc color GUICtrlSetBkColor($Combo1,0xFFFFFF) EndSwitch WEnd

      I don't have any experience compiling AutoIt scripts or know of any best practices regarding said scripts so I was wondering, what are some of the options for passing data to complied scripts? Here's an example of what I mean by "option": Writing data to a text file, then running a script which reads the data from that text file.
      Thanks!
      I apologize if this topic is a little lackluster

      Hi
      so i ran into a Problem i didn't expect to get stuck on.
      It sounds simple (and probably is) but i can't seem to get it to work
      So i created a Combobox and filled it with some things from an array which worked fine.
      $combobox = GUICtrlCreateCombo($list[0], 160, 200, 265, 25, BitOR($CBS_DROPDOWN,$CBS_AUTOHSCROLL)) GuiCtrlSetData($list, "|" & _ArrayToString($list,Default,1),$list[2]) GUICtrlSetFont(-1, 9, 400, 0, "Arial") Now i want to change the style of the combobox from $CBS_DROPDOWN to $CBS_DROPDOWNLIST via a checkbox.
      $Checkbox1 = GUICtrlCreateCheckbox("Checkbox1", 160, 96, 105, 25) Case $Checkbox1 If GUICtrlRead($Checkbox1) = $GUI_CHECKED Then Call ("Read_only") Else Call ("Edit") Endif Func Read_only() GUICtrlSetStyle ($Combobox1,something to change it to $CBS_DROPDOWNLIST) EndFunc Func Edit() GUICtrlSetStyle ($Combobox1,something to change it to $CBS_DROPDOW) EndFunc I tried using $CBS_DROPDOWN and $CBS_DROPDOWNLIST but it simply does nothing.
      I also tried $ES_READONLY which kinda worked, it changed the combobox so i couldn't change the input via dropdown anymore but i could still type in it via keyboard (which i dont want).
      It's essential that its Editable but once the checkbox is checked the combobox becomes readonly so you can't type in it anymore but you can still choose between the items in the list. (It does not have to save your current input if you write something in it and then check the Checkbox it would be best if it would simpy jump back to the first item in the list)
      Im sure this is a simple thing but after long google search im tired of my stupidity can someone give me a push in the right direction?

      Currently, I'm working on a program that will display Dialog boxes with either Yes or No.
      For each dialog, I reward the user with X amount of Credits.
      I'm hoping to output the amount of credits to a cell in a column (there will be 20 different columns).
      It will only post to a row that is equal to today's date (first column). If no row exists yet with the current date, it will start a new row.
      Any suggestions?
      Thank you
