What can I do to avoid the program stopping with an ADO error? It does not seem to be "trappeable"

Example:

objComm.CommandText = "INSERT INTO CorpExtractType (CorpCode, ExtractTypeID) VALUES ('" & sCorpCode & "'," & CStr(iExtractTypeID) & ")"
objComm.Execute()

This may fail due to a duplicate key for example, but I don't want to check for each command to see if the record already exist as it would slow things down. I just want to ignore any errors, but it won't play

Putting a try-catch arround it does not help as it bombs on the objcomm.Execute statement.
