But the provider costs $99. Another thing: How long will they continue to support it? Plus the fact that you will have to entirely rewrite all parameter queries to use : instead of @. Anyway, if you still have the time, please test whether unnamed parameters using ? works also. If that is the case, then this provider is a very viable solution at a cost of $99. But if parameters using ? do not work. I will not use this provider! Because it will make portability issues too great to bear. I use SWSoft's OleDb provider. It's not supported but it works. I only have followed some guidelines and voila, I have developed applications that are easily portable from MS Access to MySQL and to MS SQL Server.
