How to use functions embeded Access 2003 such as "POWER(),LN()",while using VC++ to operate Access DataBase?

So, what you really want to do is call VBA functions from MS Access queries? This page explains how to do that.

I don't really follow you. If you want to use a VBA function in an Access query, just create your own UDF that wraps that VBA function, then you can use that UDF in your Access query. And if you want to use some Access query function from VC++, you can make database calls to an Access DB from VC++. Are you saying you want to use VC++ functions from an Access query? If so, I do not know if that can be done (although I imagine that too can be done by going through VBA as an intermediary).

Thanks to "aspdotnetdev"
2^2 is OK.
But how about LN()?It still doesn't work.And other functions?
The core of my question is "How to use functions embeded(inner?) Access 2003 such as "POWER(),LN()",while using VC++ to operate Access DataBase?"
I have check some chinese sites,as if there is no method to solve it.In fact these functions are embeded in Access2003,one can use it by VBA.But HOW?
Thank you again!

Thanks again!
I'ii read it carefully right now!

After having read for a long time,I don't know how to use VBA in my VC++ program!
Will you plea tell me how to do it?
Sorry for my much questions!
Thanks to "aspdotnetdev" Again. :-D

After "aspdotnetdev"'s telling.
I get to know that,there is no way for my original question.One must writes his own code to get the functions in VC++ after querying from access table the values of some fields.
Good Luck! "aspdotnetdev"!
yours sincerly.

Finally,I find that the functions used while using VC++ to operate Access DataBase with ADO are the same in ASP.And all the elementary mathmatics functions can be used.
(For example:
power()->"^";ln()->"log()")
Thanks!!!
