I have just installed the MSDE (free version) and coming from being an old AccessDB user, I'm a bit confused on just what I need to do in order to get things rolling.
First off, I have created a new database in the data listing in the IDE.. I have added some tables..
Now I need to figure out how to connect to my database in pure code. Does anyone have any good examples or locations of examples that would help me get on my way?
Thanks Pirate...
A couple questions,
What connection should I if all I'm doing is connecting to my database locally? Standard or Secured?
Second, should the application be connectionless? In vb6 with access, I would establish a connection and keep it alive for the life of the application being open. But I read somewhere that the application should open a new connection , process the data then close the connection, is this true?
This is the simple form of SQL connection (locally) .
Absolutely , I agree with closing the connection when you're done .New connection objects are added to the connection pool , this could slow things down , so why don't you create global connection object and use it along the way .Code:'"Standard Security:"
"Data Source=YourComputerName;Initial Catalog=DatabaseName;User Id=sa;Password=asdasd;"
Ok cool.. Since my application is multithreaded, will a global connection object work? basically it's a online server using asyncronous sockets, so the possibility of the connection object being accessed at the same time is pretty good. Is the connection object multithreaded safe or would I need to take a different approach then?Quote:

From MSDN
I've never done like this before , So I can't be sure of the answer .Quote:
