Access Form Error Handling
Error Event Exit Event VBA Timer Event Undo Event Table access form_error Level Triggers Access Error Event Example VBA Form Error Event Examples - Code Samples Visual access 2013 error handling Basic Error event arises when a run-time error occurs in Access on the current form. Error Event Visual Basic Example: It is good practice to https://msdn.microsoft.com/en-us/library/office/ff836345.aspx have an On Error event handler in each form. In this example we simply trap the error and display a message to the user. Private Sub Form_Error(DataErr As Integer, Response As Integer) Select Case DataErr Case 3022 MsgBox "This field must contain unique values." Case 3023 http://www.blueclaw-db.com/access_event_programming/errorevent.htm MsgBox "put appropriate error text here" End Select Response = acDataErrContinue Resume ok_exit ok_exit: End SubThe response argument can have either of two values: acDataErrContinue: Ignore the error and continue without displaying the Microsoft Access error message. acDataErrDisplay: Display the Microsoft Access error message. This is the default setting.If you are using Global Variables in your Access database and you have a subroutine without an error handler then you will lose your global variable values if an error occurs. This is one of the primary drawback in using Global Variables.

See solution in other versions of Access: Access 2007 Access 2003 Question: In Microsoft Access 2003/XP/2000/97, I have a form that is linked to an Oracle table. When I enter duplicate data, I receive an error message "ODBC - failed... Unique Constraint violated...". Is it possible to define a custom message to ms access on replace the system error message whenever the primary key is violated? (ie: duplicate record) Answer: Yes, you can override the system error messages with your own messages. In your case, you want to place code on the Form's On Error event. For example, you could place the following code on the Form's On Error event to trap the primary key violation: Private Sub Form_Error(DataErr As Integer, Response As Integer) If DataErr = 3146 Then MsgBox ("You have violated the primary key.") Response = 0 End If End Sub Now, whenever a user tries to enter a record that violates the primary key, the following error message will appear: Share this page: Advertisement Back to top Home | About Us | Contact Us | Testimonials | Donate While using this site, you agree to have read and accepted our Terms of Service and Privacy Policy.

owner you will not want users to edit data in MS Access tables directly. It's one of the reasons forms exist; some of the obvious advantages are: Specific fields can be locked or hidden The field order can be changed Event-handling can be implemented However, errors in forms can occur due to inadequate data handling. If this happens the messages displayed are often not very user-friendly. For a common user following message looks quite intimidating: "The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate values and try again." This is especially true for forms with a datasheet view since they display multiple records. To address this issue I've created a generic solution to handle data-related form errors. It consists of two components: 1. Generic code The routine HandleFormError is called from the indivual Form_Error events. Therefore insert following code it in a vba module: 'Constants Public Const APP = "My application" Public Const ERR_ONETOMANYCONFLICT = 3101 Private Const ERR_RELATEDRECORDS1 = 3200 Private Const ERR_RELATEDRECORDS2 = 3201 Private Const ERR_REQUIREDDATA = 3314 Private Const ERR_DUPLICATEKEY = 3022 Private Const ERR_DATATYPE = 2113 Private Const ERR_INPUTMASK = 2279 Private Const ERR_NULLKEY = 3058 Private Const ERR_NULLVALUE = 3162 Private Const ERR_ZEROLENGTHSTRING = 3315 Private Const ERR_DATAVALIDATION1 = 2107 Private Const ERR_DATAVALIDATION2 = 3317 Private Const ERR_ITEMNOTINLIST = 2237 ' Handle data-related form errors by showing user-friendly messages.
