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 error number : -2147217900 vba advantages are: Specific fields can be locked or hidden The field order can

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 https://msdn.microsoft.com/en-us/library/office/ff836345.aspx 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 http://www.redcirclesoftware.com/handling-ms-access-form-errors-generically/ 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. ' Assign the appropiate return value to the Response parameter. Public Sub HandleFormError(oForm As Form, _ DataErr As Integer, ByRef Response As Integer) Const NEXT_MSG = "See next message for details." Select Case DataErr Case ERR_REQUIREDDATA MsgBox "Required value missing!" & vbCr & _ NEXT_MSG, vbInformation, APP Response = acDataErrDisplay Case ERR_RELATEDRECORDS1, ERR_RELATEDRECORDS2 MsgBox "Relation conflict!" & vbCr & _ NEXT_MSG, vbInformation, APP Response

Error Event Visual Basic Example: It is good practice to error handling 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 access form error 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.
