Ms access prevent a form from updating a validated record

You will also need to implement macro error handling (new in Access 2007.) The problem still occurs if you use the Close method in VBA code. If you are using a Microsoft Access database application for data entry you will want to ensure the quality of the data that is being entered.This will in turn deem your data to be more accurate and useful to all database users.A macro condition is an expression that enables a macro to perform certain tasks only if a specific situation exists.The Before Update event does not apply to option buttons, check boxes, or toggle buttons in an option group. Using the following code, we can display the message box to the user, asking them to confirm if they would like to make the changes or not: Private Sub Form_Before Update(Cancel As Integer) 'Provide the user with the option to save/undo 'changes made to the record in the form If Msg Box("Changes have been made to this record." _ & vb Cr Lf & vb Cr Lf & "Do you want to save these changes?" _ , vb Yes No, "Changes Made...") = vb Yes Then Do Cmd. When you enter data into a form, Access saves the record automatically.

#3 works, but older versions of Access do not generate a message if the save fails. Develop the habit of explicitly saving whenever you do anything that requires the record to be saved, e.g.

#4 specifies which form, and gives an error message if the save fails. "The property could not be set"), and the approach does not work in Access 1 or 2, but it is the most reliable approach unless you are working with the ancient versions. applying or removing a Filter or Order By property, changing a Record Source, or moving to another record.

In recent versions, you can also avoid the problem if you use the Close action in a macro.

For example, you may want to perform certain tasks in the database only when a specified condition it true; you might want the macro to check and see if a field in your database form contained a value, if not, the macro will execute a command to prevent you from saving the record.

When creating the user interface in Microsoft Access, the database designer should always be looking at ways to simplify the data entry process, prevent bad data from getting into the database or ask for confirmation when changes have been made to existing data.
