VBA Automation Error

In this Article

This tutorial will explain what a VBA Automation Error means and how it occurs.

Excel is made up of objects – the Workbook object, Worksheet object, Range object and Cell object to name but a few. Each object has multiple properties and methods whose behavior can be controlled with VBA code. If the VBA code is not correctly programmed, then an automation error can occur. It is one of the more frustrating errors in VBA as it can often pop up for no apparent reason when your code looks perfectly fine!

(See our Error Handling Guide for more information about VBA Errors)

Referring to a Variable no Longer Active

An Automation Error could occur when you are referring to a workbook or worksheet via a variable, but the variable is no longer active.

When we run the code above, we will get an automation error. This is due to the fact that we have opened a workbook and assigned a variable to that workbook. We have then closed the workbook but in the next line of code we try to activate the closed workbook. This will cause the error as the variable is no longer active.

If we want to activate a workbook, we first need to have the workbook open!

Memory Overload

This error can also sometimes occur if you have a loop and you forget to clear an object during the course of the loop. However, it might only occur sometimes, and not others- which is one of the reasons why this error is can be so annoying.

Take for example this code below:

The variable is declared as an Object, and then the SET keyword is used to assign an image to the object. The object is then populated with an image and inserted into the Excel sheet with some formatting taking place at the same time. We then add a loop to the code to insert 100 images into the Excel sheet. Occasionally this causes an automation error, but sometimes it doesn’t – frustrating, right?

The solution to this problem is to clear the object variable within the loop by setting the object to NOTHING – this will free the memory and prevent the error.

DLL Errors and Updating Windows

Sometimes the error occurs and there is nothing that can be done within VBA code. Re-registering DLL’s that are being used, making sure that our Windows is up to date and as a last resort, running a Registry Check as sometimes the only things that may work to clear this error.

A good way of avoiding this error is to make sure that error traps are in place using the On Error Go To or On Error Resume Next routines.

Excel automation fails second time code runs

Symptoms

While running code that uses Automation to control Microsoft Excel, one of the following errors may occur:

In Microsoft Excel 97 and in later versions of Excel, you receive one of the following error message:

Error message 1

Run-time error ‘1004’:
Method ‘ ‘ of object ‘_Global’ failed

Error message 2

Application-defined or object-defined error

In Microsoft Excel 95, you receive one of the following error messages:

Error message 1

Run-time error ‘-2147023174’
OLE Automation error

Error message 2

Run-time error ‘462’:
The remote server machine does not exist or is unavailable.

Cause

Visual Basic has established a reference to Excel because of a line of code that calls an Excel object, method, or property without qualifying the element with an Excel object variable. Visual Basic does not release this reference until you end the program. This errant reference interferes with automation code when the code is run more than one time.

Resolution

To resolve this problem, modify the code so each call to an Excel object, method, or property is qualified with the appropriate object variable.

Status

This behavior is by design.

More Information

To automate Microsoft Excel, you establish an object variable that usually refers to the Excel Application object or the Excel Workbook object. Other object variables can then be set to refer to a Worksheet, a Range, or other objects in the Microsoft Excel object model. When you write code to use an Excel object, method, or property, you should always precede the call with the appropriate object variable. If you do not, Visual Basic establishes its own reference to Excel. This reference might cause problems when you try to run the automation code multiple times. Note that even if the line of code begins with the object variable, a call may be made to an Excel object, method, or property in the middle of the line of code that is not preceded with an object variable.

The following steps illustrate how to reproduce this issue and how to correct the issue.

Steps to reproduce the behavior

Start a new Standard EXE project in Visual Basic. Form1 is created by default.

On the Project menu, click References, and then check the Object Library for the version of Excel that you intend to automate.

Place a CommandButton control on Form1.

Copy the following code example to the Code Window of Form1.

On the Run menu, click Start, or press F5 to start the program.

Click the CommandButton control. No error occurs. However, a reference to Excel has been created and has not been released.

Click the CommandButton control again. Notice that you receive one of the error messages that are discussed in the «Symptoms» section.

Note The error message occurs because the code refers to the method of the cell without preceding the call with the
xlSheet object variable.

Stop the project and change the following line of code:

Change the line of code to resemble the following line of code.

Run the program again. Notice that you can run the code multiple times without receiving an error message.

Vba automation error что это

Вроде как на ровном месте (т.е. до сегодня пару лет работало) вот такая строчка кода:

Set fs = CreateObject(«Scripting.FileSystemObject»)

стала вызывать вот такую ошибку:

Run-time error ‘-2147024770 (8007007e)’:
Automation error

Собственно, это использовалось для последующей проверки ссуществования файла (FileExists). И вот.
Подскажите, пожалуйста, что тут может быть? Библиотеки слетели? Куда смотреть?

Так всегда происходит , когда люди пренебрегают родными функциями и используются посторонние библиотеки.

Посмотрите, есть ли ссылки на библиотеки Microsoft Scripting Runtime

Спасибо. Именно это — Microsoft Scripting Runtime! Сбилась (в системе) регистрация библиотеки scrrun.dll. А в Excel (Tools — References) «галка» на неё и не стояла. И сейчас не стоит, но всё работает!Т.е. системные библиотеки сами подтягиваются? А вообще в такой ситуации нужно устанавливать reference?

Это кстати, позволяет избежать проблем, связанных с различными версиями (при передаче файла другим лицам)

что Naeel Maqsudov предлагал . Application.Run

Первоисточник конечно всегда лучше, но это действительно было давно, к тому же, на другом форуме, да и ответ был довольно краток и сводился к тому, что вызывать процедуры можно так :

Vba automation error что это

прошу помочь!
Выскочила такая «бяка» при запуске ранее рабочего макроса. Подозреваю, что что-то с настройками самого Ёкселя (либо ВБА), поскольку эксельный файл с этим макросом даже не хочет сохраняться («Документ не сохранен»). Хотя файлы с другими макросами вполне работоспособны. Офис-2003, в настройке безопасности доверялки подключены.

зы. Сколько уж зарекался оставлять свой комп коллегам

Automation error (Error 440)

When you access Automation objects, specific types of errors can occur. This error has the following cause and solution:

An error occurred while executing a method or getting or setting a property of an object variable. The error was reported by the application that created the object.
Check the properties of the Err object to determine the source and nature of the error. Also try using the On Error Resume Next statement immediately before the accessing statement, and then check for errors immediately following the accessing statement.

ошибка при установке (получении) свойств обьекта.
рекомендуют использовать On Error Resume Next чтобы в свойствах Err получить более детальную информации о произошедшем.

автору на заметку — это не решит проблемы, но должно поднять настроение. при первом прочтении — я плакал.
