From: Geoff Schaller on 22 Apr 2010 17:42 Hello Tyrone. Ok, then that is a shame. MySQL has always had difficulty on the OLEDB front but there are drivers. You must buy them (although I do not think they are expensive) but without them you cannot use ADO. I say 'unfortunate' because ODBC is an older technology (which ADO supports) and so VO2Ado is of limited value. VO2Ado is recommended because you can basically use your DBF code - all the methods and properties you know and love are still supported. It is a pity your web guys have limited you to MySQL. Most ISPs now offer MS SQL by default and MySQL if requested. It is an indication of the maturity of MS SQL for web based activity.

Some bugs were corrected in these last versions If you could choose I also recommend sql server. (The future of mysql is not clear) But if you have no chance it's not so pitiful Best regards Jorge Accinelli
From: E®!k /!$$E® on 22 Apr 2010 02:08 Willie, Geoff, I agree with you both that Vo2Ado is the way to go in a Win32 app development, but.... how is TW going to use MySql with (VO2)Ado?
