Connecting To Mysql Database From .NET?

Sep 19, 2011

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.

Connecting To A MySQL Database?

Jun 14, 2010

I have a VB.NET application and I need it to be able to display rows from a MySQL database. How would I do this?

Update: Another thing that I could do is have the app get a PHP page from the site that shows the DB, and gets the page every 10 seconds or so.

Connecting To My MySQL Database - "Error: The 'MySQLProv' Provider Is Not Registered On This Local Machine"

Jun 10, 2010

I 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?

Connecting To Remote MySQL Server?

Jun 23, 2011

I have developed a frontend app using VB 2010 which is to connect to a remote MySQL server. My server has an internal IP address of 202.56.20.72 and an internal IP address of 192.168.20.44.

When I use the internal IP in my connection string and connect over LAN, the whole thing works fine. But when i changed the IP to the external address and tried to connect to the server over the internet, I get an error something like 'Failed to connect to MySQL server for user 'user'@'localhost', [using Password=NO]. This means that for some reason, it is not connecting to the server at all.

MYSQL Not Connecting - Object Reference Not Set To An Instance Of An Object

I'm getting the following error while attempting to open my MySql connection:Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.I've included my code below with the offending statement italicized:

Dim mySqlconnection1 As New MySqlConnection
mySqlconnection1.ConnectionString = "Database=prof_dev;Data Source=helpdesk;User ID=wayne;Password=1961"
Dim SelectQuery As String = "Select * FROM employee"

[code]....

It appears that I'm just not connecting with my MySql Db. Any ideas??? I'm certain that I' m using the correct information in the string.
