Elements of Run-Time Error Handling
When you're programming an application, you need to consider what happens when an error occurs. An error can occur in your application for one of two of reasons. First, some condition at the time the application is running makes otherwise valid code fail. For example, if your code attempts to open a table that the user has deleted, an error occurs. Second, your code may contain improper logic that prevents it from doing what you intended. For example, an error occurs if your code attempts to divide a value by zero.

I get the error message "Could not delete from the specified tables"
When you run a delete query (delete query: A query (SQL statement) that removes rows matching the criteria that you specify from one or more tables.), Microsoft Office Access 2007 may display the error message Could not delete from the specified tables. This article lists cases in which you can use a delete query, explains why the error message appears, and provides steps for correcting the error.
Avoiding divide by zero errors in Access
If you try to divide a number by zero in Access, you receive a #DIV/0 error if you are in a form or report, or a #ERROR error if you are in a query. To avoid a divide by zero error, you can use the IIF function to set the results field to a zero-length string ("") if the divisor in a calculation is zero. You can then search the field for any values that contain a zero-length string and flag the results. The following steps demonstrate this technique by creating a table and a bound form, inserting three text boxes, and entering an expression.

Validating Missing Data by Responding to Data Entry Events
We can use various techniques for validating data being entered into our database, as seen in the Validating Data in Microsoft Access article, however sometimes our validation routines can be overly restrictive. There may be occasions where we need to be more flexible in our approach, and we may just want to warn the users of the database that data is missing when they are entering a record into the form. When we are entering the data, it is possible to respond the the data entry event, and use a Microsoft Access MsgBox function to perform different actions depending on what the database user wants to do.

Run-time error on form
I have set up a database for monitoring users of our financial system. with the user ID being numeric, and everything has worked fine. Recently the administrators of the database have asked me to alter the database to accept alphanumeric ID's. After changing the data type to text, certain of my forms that use a filter are producing the following error message. "Run-time error '2501' The ApplyFilter action was cancelled. You used a method of the DoCmd object to carry out an action in Visual Basic, but then clicked Cancel in a dialog box." I know that the error message is due to the change in data types, because when I delete the alphanumeric data and change the type back, the forms work again.

Validating Required Data in Microsoft Access Text boxes
You may want to prevent users from saving Microsoft Access records with missing information, especially if this data is important. There are several approaches to this and various methods can be used in Microsoft Access, which can be applied in various places.

You will need to put your validating code in the Microsoft Access form's BeforeUpdate event. This way you can cancel the saving or adding of a record with missing info.

I filtered the subform or subdatasheet, but it did not filter the main form or datasheet. The returnset is not sorted properly. I want to test my filter before I distribute the database.
