How can I get the value of the variable in combobox


Recommended Posts

Hello

Before start asking question, I apologize for my poor english

(So I'm writing this topic using translator :sweating:)

 

This is my question

 

Among many volumes in computer, I want to get the letter of volume.

So I wrote this code

#include <ButtonConstants.au3>
#include <ComboConstants.au3>
#include <GUIConstantsEx.au3>

Opt("GUIOnEventMode", 1)

$Form1 = GUICreate("title", 291, 246, 184, 261)
GUISetOnEvent($GUI_EVENT_CLOSE, "Exitapp")
$Combo1 = GUICtrlCreateCombo("select volume", 16, 32, 257, 25, 0x0003)
GUICtrlCreateGroup("", -99, -99, 1, 1)
$Button1 = GUICtrlCreateButton("Check", 16, 70, 257, 25)
GUICtrlSetOnEvent($Button1, "Func_Check")
GUISetState(@SW_SHOW)

Local $var = DriveGetDrive("All")
If Not @error Then
   For $i = 1 To $var[0]
      $DriveType = DriveGetType($var[$i])


      If $DriveType = "Removable" Or $DriveType = "Fixed" Then
         $letter = StringUpper($var[$i])
         GUICtrlSetData($Combo1, $letter)
      EndIf
   Next
EndIf

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

    EndSwitch
 WEnd

;;;;;;;;;;;;;;;;;;;;;;;;; UDF Area ;;;;;;;;;;;;;;;;;;;;;;;;;
 Func Func_Check()
    MsgBox(0, "test", $Combo1)
 EndFunc

Func Exitapp()
   Exit
EndFunc

 

but, 

When I click the button, I can see only " 3 " 

According to a lot of topics what i saw, in case using " | ", I can get the value what I want.

But I have no idea how to use " | " in my code. 

If there's a good way I do not know, please let me know.

 

Thank you for reading. Have a good day.

@NewBie_2018 Welcome to the forum. Try changing this:

MsgBox(0, "test", $Combo1)

To this:

MsgBox(0, "test", GUICtrlRead($Combo1))

See the help file on GUICtrlRead for more info.

It is not a problem, we can move the topic. Did my suggestion fix the issue for you?
