I'm having some trouble setting up a working connection to a mysql database from Visual Studio 2010.After downloading and installing the mysql-net connector, I set up a simple testing database in Xampp and experimented around a bit until I managed to read some values from the database and inserting new ones.I'm trying to access another database on a remote server and all I get is an error message: Unable to connect to any of the specified MySQL hosts.Basically, I'm only trying to execute this code:
Dim con As New MySqlConnection("Server=111.11.111.111;Uid=root;Pwd=mypwd;Database=mydb;")
con.Open()
con.Close()
(server ip looks a bit different of course)When I access my local database, it looks quite similar:
Dim con As New MySqlConnection("Server=127.0.0.1;Uid=root;Pwd=;Database=test;")
con.Open()
con.Close()
Nevertheless, I can access the remote database easily using a simple PHP script... no problems there.

View 8 RepliesI have a MySQL database I've created for my website, [URL]. I want to query the database, but I am unsure how to connect.
This is the code I'm using:
Code:
Dim sConnection As String = "Provider=MySQLProv;Data Source=my_database;User Id=my_user;Password=my_pass;"
Dim bSuccess As Boolean = True
[CODE]............
The MsgBox() returns a message that says: "Error: The 'MySQLProv' provider is not registered on this local machine". All I want to do is access the table in my database, is it possible? (also, without installing anything additionally?)
Does the .NET framework include ways to access MySQL databases easily?

I also have a custom SiteMapNode which has to be constructed with a custom Page argument.[code]Should I return false in AuthorizeCore() to have everything work according to default authorization protocols? (What are these?) Or should I throw my exception.SiteMap.CurrentNode is Null / Nothing (in AuthorizeCore()) if the page which is requested is not accessible to the user (obviously). How should I change my implementation? I want to keep the functionality that the Page objects are only loaded once, so I need to store them somewhere.

I'm attempting to create and populate a table in a new Microsoft Access (Jet) database using VB.Net 2008 Express under Windows XP Pro SP3. The database and table are being created properly, but loading the table proceeds VERY slowly. When I am loading the table, no complicating factors that might impact performance, such as indexes or table relationships have been defined. The table to be loaded is made up of relatively short rows consisting of three single byte columns, and one (four byte) integer column. I am loading approximately 16 million rows, and this is literally taking hours, while the same data can be interactively imported into Microsoft Access from a .csv file in minutes. I am trying to batch load the rows, 64K rows at a time, in order to avoid the overhead of individually transacting/committing each row individually, but suspect that I must not be doing something right. Key code that I am using for this process is provided below.
