Run time error 340

This article features error number Code 340, commonly known as Control array element ‘item’ doesn’t exist described as You used an invalid index value to refer to an element in a control array.

About Runtime Code 340

Runtime Code 340 happens when Windows fails or crashes whilst it’s running, hence its name. It doesn’t necessarily mean that the code was corrupt in some way, but just that it did not work during its run-time. This kind of error will appear as an annoying notification on your screen unless handled and corrected. Here are symptoms, causes and ways to troubleshoot the problem.

Definitions (Beta)

Here we list some definitions for the words contained in your error, in an attempt to help you understand your problem. This is a work in progress, so sometimes we might define the word incorrectly, so feel free to skip this section!

Element — In metadata, the term data element is an atomic unit of data that has precise meaning or precise semantics.
Control — Use this tag for programming scenarios related to controls interactive elements of the user interface.
Array — An array is an ordered data structure consisting of a collection of elements values or variables, each identified by one single dimensional array or vector or multiple indexes

Symptoms of Code 340 — Control array element ‘item’ doesn’t exist

Runtime errors happen without warning. The error message can come up the screen anytime Windows is run. In fact, the error message or some other dialogue box can come up again and again if not addressed early on.

There may be instances of files deletion or new files appearing. Though this symptom is largely due to virus infection, it can be attributed as a symptom for runtime error, as virus infection is one of the causes for runtime error. User may also experience a sudden drop in internet connection speed, yet again, this is not always the case.

(For illustrative purposes only)

Causes of Control array element ‘item’ doesn’t exist — Code 340

During software design, programmers code anticipating the occurrence of errors. However, there are no perfect designs, as errors can be expected even with the best program design. Glitches can happen during runtime if a certain error is not experienced and addressed during design and testing.

Runtime errors are generally caused by incompatible programs running at the same time. It may also occur because of memory problem, a bad graphics driver or virus infection. Whatever the case may be, the problem must be resolved immediately to avoid further problems. Here are ways to remedy the error.

Method 1 — Close Conflicting Programs

When you get a runtime error, keep in mind that it is happening due to programs that are conflicting with each other. The first thing you can do to resolve the problem is to stop these conflicting programs.

Open Task Manager by clicking Ctrl-Alt-Del at the same time. This will let you see the list of programs currently running.
Go to the Processes tab and stop the programs one by one by highlighting each program and clicking the End Process buttom.
You will need to observe if the error message will reoccur each time you stop a process.
Once you get to identify which program is causing the error, you may go ahead with the next troubleshooting step, reinstalling the application.

Method 4 — Re-install Runtime Libraries

You might be getting the error because of an update, like the MS Visual C++ package which might not be installed properly or completely. What you can do then is to uninstall the current package and install a fresh copy.

Uninstall the package by going to Programs and Features, find and highlight the Microsoft Visual C++ Redistributable Package.
Click Uninstall on top of the list, and when it is done, reboot your computer.
Download the latest redistributable package from Microsoft then install it.

Click the Program which is causing the runtime error, then you may choose to uninstall or click Advanced options to reset the application.

Method 3 — Update your Virus protection program or download and install the latest Windows Update

Virus infection causing runtime error on your computer must immediately be prevented, quarantined or deleted. Make sure you update your virus program and run a thorough scan of the computer or, run Windows update so you can get the latest virus definition and fix.

Method 5 — Run Disk Cleanup

You might also be experiencing runtime error because of a very low free space on your computer.

You should consider backing up your files and freeing up space on your hard drive
You can also clear your cache and reboot your computer
You can also run Disk Cleanup, open your explorer window and right click your main directory (this is usually C: )
Click Properties and then click Disk Cleanup

Method 6 — Reinstall Your Graphics Driver

If the error is related to a bad graphics driver, then you may do the following:

Open your Device Manager, locate the graphics driver
Right click the video card driver then click uninstall, then restart your computer

Method 7 — IE related Runtime Error

If the error you are getting is related to the Internet Explorer, you may do the following:

Reset your browser.

For Windows 7, you may click Start, go to Control Panel, then click Internet Options on the left side. Then you can click Advanced tab then click the Reset button.
For Windows 8 and 10, you may click search and type Internet Options, then go to Advanced tab and click Reset.

Disable script debugging and error notifications.

On the same Internet Options window, you may go to Advanced tab and look for Disable script debugging
Put a check mark on the radio button
At the same time, uncheck the «Display a Notification about every Script Error» item and then click Apply and OK, then reboot your computer.

If these quick fixes do not work, you can always backup files and run repair reinstall on your computer. However, you can do that later when the solutions listed here did not do the job.

Run-Time error 340?

So in my program i’m attempting to have a control array of command buttons originally disabled, have the user perform an action enabling the command buttons. when the user clicks the command buttons the go invisible. the form with these buttons is then unloaded and reloaded resetting the command buttons to their original state( visible and disabled) except that when the form is reloaded and the user attempts to enable the buttons again i get a runtime error 340 for the last button that was clicked prior to unloading the form (sometimes the button itself still works but is wiped blank ie caption and colour erased) does anyone know what the cause of this error is and how it can be fixed? Thanks.

Re: Run-Time error 340?

Without seeing your code that unloads/loads the array, my gut feeling is that you can’t unload a control that is currently being executed? If that is the case, a timer may work.

1. Add timer to the form, set it’s Enabled property to True and interval small, say 100
2. When the user clicks the button, change Timer’s Enabled property to True
3. In the timer’s Timer event, disable the timer & unload/reload controls

The idea is that the short delay will allow the button to finish. If that doesn’t work, we’ll need to see some code

Re: Run-Time error 340?

Count the number of command buttons you have in your array….then debug your program to see what the value that is being used in trying to make visible and disabled. If you have an array of 8 buttons, your upper limit of that array will be 7 (assuming you did not change from the default, starting with command1(0). I just assume the value you are trying to use to make your buttons visible again is one more than in the upperbound value of your array.

Re: Run-Time error 340?

not that didnt work im afraid. the control array is re-enabled like this (its original state being disabled)

For index = 0 To 25

cmdLetters(index).Enabled = True

Next index

Re: Run-Time error 340?

btw there are 26 buttons in the control array

Re: Run-Time error 340?
If your array is contiguous (no elements are skipped) then this is probably what you want
Code:

For index = 0 To cmdLetters.Ubound
If cmdLetters.UBound is < 25 then you have another problem. What is the value of Index when the error occurs?

its always equal to the button clicked last prior to original unloading of the form all the others work fine its just the one clicked last

And that timer solution didn’t work? Let us see some of your code, specifically the routine that loads/unloads the array

Re: Run-Time error 340?

im not sure what you mean by that the array isnt loaded or unloaded at all its state is just changed between visible and invisible. disabled/enabled .should i be loading this somehow i dont really know

Re: Run-Time error 340?

Ok, I thought you were loading the buttons at runtime, dynamically. Then let us see the code the unloads/reloads the form. It might just be 2 lines of code, but just to be sure, let’s see that click event

Re: Run-Time error 340?

lol, that’s what I was afraid of and I should’ve been more specific. That’s everything that happens in that click event? Then what happens in the form’s Load event? Where is the code that enables/disables the buttons and what does that code look like. Put yourself in our place… We have no idea how your code is written, how events call to other routines, etc. Give us as much as you can so we can visualize the process.

Personally, I don’t think I’ve ever seen an error that the array item didn’t exist when the control actually existed. And I’m still leaning towards the button’s click event not fully being executed from mouse down to mouse up is the heart of the problem.

Re: Run-Time error 340?
first one:

Code:

Private Sub cmdPlay_(click)

Second one:

Code:

Private Sub cmdBegin

the idea is that frmGame is unloaded displaying frmMenu which is still open as it is the form that opens when the program is run. when you click cmd Play it opens frmGame. So the control array is in frmGame and its all disabled, the array is enabled when you click cmdBegin. induvidial command buttons in the array are set to invisible after they are clicked then when the game ends frmGame is unloaded displaying frmMenu (since it was already there). the user can then click cmdPlay again to play another game except that when frmGame is reloaded and they click cmdBegin to enable the array (which should be disabled at this point since frmGame has been unloaded and reloaded as the control array is disabled in the form design) it gives the error when it tries to enable the last command button that was clicked
Mar 28th, 2015, 12:30 PM

#20
Re: Run-Time error 340?
A couple questions

1. cmdBegin is in frmGame?
2. If so, why unload the form and reload it? Why not just Enable the buttons

To try to replicate the scenario, I did this based on what I understand from your post
1. Created a frmMenu that (for simplicity) has a button that when clicked calls frmGame.Show
2. Created a frmGame that has an array of 26 disabled buttons + another enabled button: cmdBegin
3. When cmdBegin is clicked, I have this code. This would not re-enable the buttons because once form is reloaded, doesn’t matter what the enabled state of buttons was before it was reloaded and you say they are default to false so they will be false once reloaded
Code:

Dim index As Long For index = 0 To 25 cmdLetters(Index).Enabled = True Next Unload frmGame frmGame.Show
4. Moving the unload/show lines of code before the loop does re-enable the buttons

If my logic isn’t similar to how you described yours, then I apologize as I’m not following. In either case, I cannot replicate Error 340

Re: Run-Time error 340?

This may help? Typically, games do not unload/reload forms to begin a new game. They usually have a separate subroutine that sets up the game/board. All the code needed to setup the game is contained in that subroutine and/or calls other needed routines from within that subroutine. Then when a new game is about to be played, that subroutine is called. It is generally called from the Form_Load event so the game is initialized when the form first loads. Then as needed, it may be called from other places from within the same form, like a «New Game» button/menu or a message box that appears after a game has been lost/won that asks, «Play Again».

The simple idea is to have one place that is called to initialize the game.

Re: Run-Time error 340?

imho, the only way that is possible is
1)an array of controls created at runtime, and an element is unloaded
or
2)an array of controls created at design time
then delete an array element at design time

Yep, that’s why I was confused also. My guess is that the OP is trying to modify code not written by him because of that comment that he didn’t know exactly how the code works. And if that is the case, it is likely the controls are loaded at runtime

Имеется массив элементов А(I). Пользователь может удалить любой элемент из этого массива. Нужно после операции удаления отсортировать этот массив, но в цикле по I при достижении индекса удалённого элемента появляется ошибка RunTime Error 340 Control array element ‘item’ doesn’t exist. Можно ли каким-либо образом удалённый элемент не рассматривать, чтобы обойти данную ошибку?

Имеется две формы. На одной из них (PerZZ) — CommandButton’s, а в качестве рисунков на них — элементы ActiveX. На другую форму (Titul) при нажатии соответствующей кнопки на PerZZ должен переноситься соответствующий элемент ActiveX. При этом кнопка на PerZZ становится неактивной.
При удалении ActiveX-а с Titul-а кнопка должна становиться активной. Но нужна проверка. Её и пытаюсь реализовать…

Visual Basic

    If Titul.TitPerZZ.Count > 1 Then
    
        For I = 1 To Titul.TitPerZZ.Count - 1
                 
                If Titul.TitPerZZ(I).Visible = True Then 'здесь выдаёт ошибку
                    For J = LBound(PZZ) To UBound(PZZ)
                        If PerZZ1(J + 1).NumberZN = Titul.TitPerZZ(I).NumberZN Then
                            PerZZ1(J + 1).Enabled = False
                            Command1(J + 1).Enabled = False
                        End If
                    Next J

Как я понимаю, у вас ситуация, покажая на эту:

Visual Basic

Private Sub Command2_Click()
Dim a(1 To 3)
Dim i As Integer
For i = 1 To 3
    Load Command1(i)
    Command1(i).Top = 0
    Command1(i).Left = i * Command1(i).Width
    Command1(i).Caption = "Button " & i
    Command1(i).Visible = True
Next
End Sub
Private Sub Command3_Click()
MsgBox Command1(2).Caption
Unload Command1(2)
MsgBox Command1(2).Caption
End Sub

Предпоследняя строка вызовет вашу ошибку.
Самый простой вариант — сделать отлов ошибки при помощи On Error. Или написать функцию, которая опять же через On Error будет проверять. Вот здесь наглядный тому пример:

По поводу функции IsNothing: в vb6 такой нет, в инете нашли:

Visual Basic

Public Function IsNothing(pvar As Variant)
    On Error Resume Next 'Handle errors here
    IsNothing = (pvar Is Nothing)
    On Error GoTo 0 'Reset error handling
End Function

Т.е. отлов ошибки через «On error» как бы происходит. Только положительного результата нет… Вот.

Почитайте, наконец, ссылку, которую я Вам дал.
Там четко описано и про Is Nothing и про требуемую функцию.

nnn,
На самом деле синтаксис неверен. Нужно Is Nothing. Например:
If ТвойКонтрол Is Nothing Then
VladConn
A, я смотрю, в чьей-то ф-ции IsNothing есть пример верного использования Is Nothing.

VladConn, в данном случае ты не прав.
Дело в том, что конструкция Is Nothing даже для выгруженных контролов в Control Array’e возвращает False. Посмотри ссылку.

Почему это я неправ? По-моему, Alexey Spirin рекомендовал Is Nothing, причем без пробела, на что (и только на это) было обращено мое внимание, поскольку отсутствие пробела повело, судя по-всему, спрашивающего по совсем ложному пути.

Виноват-виноват, пробел просутил, не спорю)
Однако в данном случае все равно дело не в Is Nothing. Is Nothing в данном случае не подходит. Просто изначально понятно не было, о каком именно случае идет речь.

Да, конечно.
Я сейчас в отпуске, так что активно не буду наверно участвовать.

UBound(arrayname[, dimension]) — Возвращает число Long, содержащее максимально возможный индекс массива arrayname указанной размерности. Если вам не всё понятно, то смотрите пример.
Пример:
DimUpper

Visual Basic

Dim MyArray(1 To 10, 5 To 15, 10 To 20) ' Объявляем массивы
Dim AnyArray(10)
Upper = UBound(MyArray, 1) ' Возвратит 10.
Upper = UBound(MyArray, 3) ' Возвратит 20.
Upper = UBound(AnyArray) ' Возвратит 10.

Т.е.

Visual Basic

dim a as integer 
...
for i=1 to UBound(MyArray)
     a=a+1
next i
text1.text=a
...

Question

I am getting Runtime Error 340- Control Array Element «0) does not exist, while executing the VB6 code for Sample Statistics.

I have created 5 labels «Random Data Sample», «Average», «Standard Deviation», «DataMin» and «DataMax» with Index property as 1, 0, 1,2, 3 respectively and also created 5 list boxes i.e. List1, List2, List3, List4 and List5 respectively for the
above labels with the code as under :

Function ArrayStats(DataArray() As Double) As Double()
Dim Res(4) As Double
     Sum = 0
     SumSquares = 0
     DCount = 0
     DataMin = 999999
     DataMax = 999999
     For i = LBound(DataArray) To UBound(DataArray)
          Sum = Sum + DataArray(i)
          SumSquares = SumSquares + DataArray(i) ^ 2
          If DataArray(i) > DataMax Then DataMax = DataArray(i)
          If DataArray(i) < DataMin Then DataMin = DataArray(i)
          DCount = DCount + 1
    Next
    Avg = Sum / DCount
    StdDev = Sqr(SumSquares / DCount - Avg ^ 2)
    Res(1) = Avg
    Res(2) = StdDev
    Res(3) = DataMin
    Res(4) = DataMax
    ArrayStats = Res()
    End Function
    
Private Sub Command1_Click()
Dim SData(100) As Double
Dim Stats() As Double

     List1.Clear
     For i = 1 To 100
           SData(i) = Rnd() * 10000
           List1.AddItem SData(i)
      Next
      Stats() = ArrayStats(SData())
      For i = 1 To 4
              lblSTATS(i - 1).Caption = Stats(i)
      Next
End Sub

Pl. help in resolving the problem.
