I am building a program for a small office and I have a little problem with the code so I thought it's better to post a topic before continiue.. I have search into google and a lot of forums about database connectivity and my problem is simillar to other but a lot of things differs.The error that I get is on executeNoQuery() and it's called {"Connection must be valid and open."} Well a lot of things may related to about that.At least now from my re-search I covered all the filds of the problem and still not fixed.

I've added a database to my application with 2 fields:"ip" address and "started" that holds the number the application was started from that specific IP.I want to upload the database to my site hosted at google.sites. When the program is started it should make a connection with the following cases:
1-no connection with the database (possible no internet available) - it should display an error message
2-there is connection, the IP is not stored on the database, it addes the IP to the database and the field "started" with the value 1
3-there is connection, the IP is stored on the database, it increments the field "started" by 1

I'm using Visual Basic/Studio 2010 Express to run my VB program using MS Access database. I'm going to convert the Access database to a SQL Server Server Express data base so I downloaded SQL Server 2008 R2 Express onto my pc with Windows 7. The installation went fine and I actually converted my Access database to SQL server.

My query is not the straightforward connection to MS Access.I am using a third application that places all data in an Access database BUT recently they changed the database so that it doesn't end in '.mdb', instead in another suffix: '.accdb'.The database is still an Access database but I cannot connect to it using the connection strings:[code]Previously I was able to use the second connection when the database name ended in '.mdb' (Database Name.mdb).
