My hosting service is Yahoo. I created a database on the server and tried to connect to it in Dreamweaver mx. When I went to connect it gave me an error message that read " HTTP error code 400 bad request". My information is correct and the database is able to be connected to b/c I wrote a php script to test the connection and it worked. I need to be able to connect to the database from Dreamweaver inorder to create any of my search pages. I would appreciate any and all help!

make sure your db. has the proper permissions to read and write for users.
Also, you should check the type of support your hosting providers offer. They usually have examples of conn Strings.

good luck.
