MySQL and DataDir: Server can not find databases

MySQL and DataDir
Server can not find databases

I've installed an Apache Server on WinXP home. It works fine.
Installed PHP and after a while got it working too, with the server,
But can not got working the MySQL connetion. I'll explain:
Put an application, wich uses php and mysql (dadabik) under c:\xxx\apache\html\dadabik and works only if the databases are located where is specified on the datadir directive (mysql\data\)
Others like php-nuke output a db related error and do not run

actual configuration:
basedir=C:/mysql
datadir=C:/mysql/data

Now the questions:

1-should I change the datadir directive to c:\xxx\apachtml\dadabik ?
in that case should I move the mysql database too?
2-I intent to use another systems like php-nuke and I don't know where it have (or will generate) their databases. ¿?

3- Even solving the former questions I won't be able to serve all of them without changing my.ini conf file and restarting mysql server :(

The big question: - There is no way to give the mysql server a list of directories, or one under wich I will be working?
or should I put all the databases together in C:/mysql/data or similar?
Thanks for any sugestion.

Have you used the MySQL console to create the databases and tables with SQL?

try this...
in DOS, type C:\mysql\bin\mysql.exe
then type show databases;

It sounds to me you haven't reached this step in your set-up...
to create a database, type CREATE DATABASE dbname

if its php-nuke you're trying to set up, i believe there's a file with the SQL code inside it...

I hope i understood your situation properly, otherwise please clarify...

Thank you for your answer.

Let's be more explicit:
"DaDaBIK is a free PHP application that allows you to easily create a highly customizable Web form interface for a MySQL database in order to search, insert, update and delete records" URL It expect to have a database already created (I did it)
I stored (the app.) on "localhost"/dadabik. Ran it and it worked, but look up for the testing database (and create the control database) on \mysql\data\ folder.
My question is: How can I get MySQL serving databases in diferent folders (if is possible) for different applicatios runing on other folders? Or should I put all the databases in the same folder as directed on datadir=C:/mysql/data or wherever?
In the last case: If I decide to change the default database folder to something like "localhost"/mydatabases/, should anything else be changed, beside the "datadir=" directive? for example, the control database installed by mysql should be moved to the new folder?

Similar thing about php-nuke. I belive it will create the needed db's on first start up, but expect MySQL be active on a specific folder. As I said, my actual instalation only works on the default folder (/mysql/data). I guess the same answer for the former topic will help on this.

Hope could be clear enough, Ruben

Oh, I think I understand your question now...

Mysql will handle the placement of the physical database files... I strongly advise you not to put your Mysql data folder in your web domain (localhost/mydatabases)... Personally, I would leave it in C:/mysql/data

I believe Mysql only requires a data folder, and it places all the database files inside that folder... You can create copies somewhere else as a backup, but the production versions will stay in the data folder (/mysql/data)

I don't think PHP nuke cares where the folder is, since it will add the databases/tables/data through the actual remote database system (the mysql daemon)... I assume DaDaBIK operates the same way...
