MS Access Forum / General 2 / May 2007Using ADODB, how do I create a msgbox when duplicate data is enter
Hello, I am having a problem creating a msgbox, when data entered through a form into a table is duplicated. I would like for a msgbox to popup, and warn the user for dupliucate data, before the actual data is entered into the table. I have an index for no duplicate set on a field in a table. How would I go about this? I have seen code for Jet, and have tried to translate it over to ADODB, but with many problems. Any help with this will be greatly appreciated. Thanks I don't know the code which is causing the problems with Jet but have you tried working with the 'match' something like: before_update from the form open the recordset and look for a match if there is a match raise the messagebox and exit the sub so the user can make the changes and otherwise resume with the record append to the table.

In the Condition (if you can't see a Condition column in the macro design window, select it from the View menu), put the equivalent of this... DCount("*","YourTable","[FieldName]='" & [TextBoxName] & "'")>0 Assign this macro on the Before Update event of your form, .
