Excel vba interrupt execution

Иногда при выполнении вполне рабочего кода может возникнуть ошибка «Code execution has been interrupted«:
Code execution has been interrupted
чаще всего она появляется в циклах (это Do … Loop, For each, For … Next). Но может проявится и на отдельных участках кода совершенно независимо от того, что делает тот или иной кусок кода. Сама по себе ошибка не является таковой — при нажатии Continue код продолжает работать и может даже дойти до конца уже без ошибок. Но что примечательно — появившись в каком-то коде однажды, эта ошибка начинает преследовать вас и при этом воспроизводится только на том ПК, на котором появилась. На других же ПК код может работать отлично и без всяких казусов.

Почему вообще появляется эта ошибка? Точный ответ на этот вопрос я, к сожалению, не дам. Только предположения: VBA тоже хранит всевозможные логи при работе и обращается к разным библиотекам. И скорее всего в какой-то момент этого хлама набирается так много, что VBE начинает «подглючивать» таким вот нестандартным образом, предполагая, что мы пытаемся выполнить параллельно два кода.

И главное: как ошибку Code execution has been interrupted устранить?
Я знаю два способа.
Способ 1 — разовый
Перед выполнением кода поставить строку:

Application.EnableCancelKey = xlDisabled

а после выполнения(перед End Sub или в любом месте, где может произойти выход из процедуры) её вернуть:

Application.EnableCancelKey = xlInterrupt

чем не нравится данный метод мне лично: свойство EnableCancelKey отвечает за возможность обработки нажатия клавиш при выполнении кода. Значение xlDisabled переводит VBA в режим «глухой обороны» — т.е. он не будет реагировать ни на какие нажатия пока не завершится выполнение кода. Догадались, чем это чревато? Правильно: если вдруг попали в бесконечный цикл или захотели прервать выполнение — ничего не получится, т.к. сочетание Ctrl+Break будет просто проигнорировано.


Способ 2 — пожизненный(почти)

После появления ошибки нажмите

Debug

, затем

Ctrl

+

Break

, затем кнопку

Play

на панели редактора VBE (зеленый треугольничек воспроизведения кода) — продолжится выполнение кода. После этого ошибка должна исчезнуть.
Главное жать не

F5

для продолжения выполнения, а именно треугольник на панели. Иначе может не сработать.


Если знаете еще способы устранения ошибки — делитесь в комментариях — это обязательно поможет кому-то спасти нервы и силы и в карму вам плюсанется :)

Break mode is entered when a running procedure stops because of either an error in the code or a deliberate act on your part (described later in this chapter).

  • Question

  • Hello all,

    Often I develop complex, long runing VBA macros for Excel 2010 (32-bit). During development, I sometimes forget to increment a loop counter (gasp!) or do a simliar thing that causes Excel to go into an infinite loop.  In these siuations, I need to break
    the running VBA code, but neither ESC nor CTRL-BREAK does anything.  The only alternative is to restart Excel 2010, but this causes all unsaved work of the macro to be lost (in addition to any unsaved code). Is there an alternative to CTRL-BREAK to interrupt
    VBA? ESC worked for me on Excel 2003, not not here. I’m on Windows 7 x-64.

    I am also wondering if autosave can fire while Excel is in such a state.

Answers

  • I thought it was only me that did this!

    I usually find that repeated Esc Clicks or holding Esc for a long time sometimes works, if the keyboard command can find a crack in the process,

    Otherwise I open the task manager Applications Tab and End the VBA task.

    Often this doesn’t work either and I end up loosing the unsaved work.

    I am still trying to remember to do a manual save at frequent intervals.

Return to VBA Code Examples

This tutorial will demonstrate how pause (break) and resume a macro in Excel.

Being able to pause a macro while testing VBA code that has been written is a useful way to work out where any ‘bugs’ may be in our code.   There are a number of ways that we can break the running of the macro, and then resume it from the point where the macro was interrupted.

The Control and Break keyboard combination

If we hold down the control key, and then press the Pause/Break key when VBA code is running, the code will immediately stop with a debug message warning us that the running of the macro has been interrupted.

VBABreaks CtrlBreak

We can then press the Continue button in the dialog box that pops up to continue running the macro.  Alternatively, if we then press the Debug button in the dialog box, the macro will highlight the position where it stopped running.  By resting the mouse over any existing variables, we can then see what is stored in the variables.  This can be very useful in debugging our code.

VBABreaks Variable Value

We can then click the Run button in the ribbon (or press F5 on the keyboard) to resume running the macro.

VBABreaks Continue

Adding Break Points to the Macro

Before starting the macro, we can insert break points into the macro in order to stop the macro as specific lines of code.

VBABreaks SetBreakPoint

We can run the code by clicking on the Run button in the Ribbon, or by pressing F5 on the keyboard.  The macro will stop at the break point.

VBABreaks BreakPoint

Press the Run button again (the caption will now say Continue) to resume the macro or press F5.

There may be other times that the running of a VBA macro may need to be paused.  This can also be done using the Wait and Sleep methods.   These methods are used more in delaying the actual progress of the macro rather than being used to debug the actual code.

For example, this line of code will delay the macro from running until 5 more seconds have passed.

Application.Wait (Now + TimeValue("0:00:05"))

You can interrupt a macro in Excel at any time by pressing Esc or Ctrl + Break.

Place a command button on your worksheet and add the following code lines:

Dim x As Long
x = 5

Do While x > 2
    x = x + 1
Loop

1. Click the command button on the sheet. This macro never stops because the part after ‘Do While’ will always be true (x will always be higher than 2).

2. To halt this infinite loop, press Esc or Ctrl + Break. The following dialog box will appear:

Code Interrupted Dialog Box

3. Click End to end the macro, click Debug to take a look at the macro in the Visual Basic Editor.

4. Add the following code line at the start of your code if you don’t want users of your program to be able to interrupt your macro (not recommended).

Application.EnableCancelKey = xlDisabled

5. Although Excel VBA resets the EnableCancelKey property automatically to xlInterrupt at the end of your macro, it’s good practice (when using the previous code line) to end your macro with the following code line:

Application.EnableCancelKey = xlInterrupt

Note: if Excel freezes and you cannot interrupt your macro anymore, press Ctrl + Alt + Delete and close Excel.
