I Downloaded MySQL Connector (the latest, 6.1.X), and i cant really understand how to use it in VB.Net... I Added it to references. All what I need to know is what imports to use, how to set connection with remote server and how do I select and insert to tables.
View 6 RepliesI'm trying to make a rather simple Visual Basic app with which I can update some tables within my MySQL databases.I've been following this tutorial from page 3 on, as the first 2 pages where on how to initialize a local MySQL database.My MySQL database is on my website, so I thought I had to use the website's name instead of "localhost". Anyways, I now use this code:
Dim connection As MySqlConnection
connection = New MySqlConnection()
connection.ConnectionString = "Server=resload.com; Uid=***; Pwd=***; Database=***;"
[code]....
But it popups (don't now whether that's a real word :p) with the message:Error Connecting to Database: Access denied for user '***'@'my ipaddress' (using password: YES)?
I am building a database application using MYSQL as the backend. The MYSQL instance will be installed remotely on a share host. I have access to SSL certificates. I'm obviously not looking for any code but, conceptually, how do I go about securing the connection using SSL between my application and the remote MYSQL database?
View 2 RepliesI 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.
I have got a MySQL database stored on a remote server. I can user PHPMyAdmin to access the database and make changes to the table, i can also use a third party piece of software to do the same however when i try and access the database through my program it says that "Access denied for user 'lukefrost'@'%' to database 'PHCAdminSystem'". However it will allow me with the same logon credentials the other ways explained above. Can anyone help me with what the problem might be?

I am probably beginner to intermediate at coding now, and want to make an application that interacts with a mysql database on my website.The application would be a Windows 7 App (Windows Forms) and i would like to contact the MySQL database and search and insert etc into it.The problem is my MySQL only allows contact from certain IP address (which you can add, but i cannot add "all")I am looking for advice on methods i could use to interact with the Database on my website, from an application which could be used by multiple users anywhere in the world.

I've came across a little problem with my tcp / ip server. My client can connect to it with 127.0.0.1 ( localhost ), and 192.168.0.X, but every remote connection fails to connect.
Here's the connection rituals:
Server
listener = New System.Net.Sockets.TcpListener(System.Net.IPAddress.Any, Port)
listener.Start()
listenThread = New System.Threading.Thread(AddressOf doListen)
listenThread.IsBackground = True
listenThread.Start()
Client
client = New System.Net.Sockets.TcpClient(IP, Port)
client.GetStream.BeginRead(readBuffer, 0, BYTES_TO_READ, AddressOf DoRead, Nothing)
I'm developing a remote control program that uses a mysql database as the bound beetween the server and the client.The only problem is that cause of mysql being really varnuable to crashes i made it in a way that it checks for information every 10 seconds so things doesnt get messy. [code] For some reason after 10 seconds the connection is mysteriously aborted and the reader gives a fatal error.How can i extend the time limit to >10 seconds ?

MVC3, VB.NET, using EF. I am working on coding up a simple function to handle checking for a valid MySQL connection. If the connection fails the test it will use the secondary server connection. This is required because our hosting provider does not provide failover or redundant MySQL servers. The problem is I tried to use a simple try catch method in the HomeController. This fails early because the Entity Framework is looking the connection that was set up when I set it up... Is there anyway to control that connection dynamically?
View 1 RepliesI have a client that wants to connect to his MySQL database using Dial-up/Modem connection. All i know is a phone number. I will be using VB.NET 2005 for this project. We also have a LAN Connection setup to other computer, but some of this computer only uses Dial-up to connect. The LAN connection works fine because i can just use the Local IP to create a connection string.But my problem is how do i get to connect to a remote server using a Dial-up? I know building a connection string require an IP to connect. Do i need to get the IP after a dial-up connection is connected or to i need to use different approach? I have a server and i have 10+ clients, the server has a T1 connection + a dial-up modem installed also.I created a POS system to all the clients, Some clients uses dial-up some uses LAN. What the server do is all the records of the clients POS will be sync to one database on the server in one table. If i'm in the server and and i selected a station/client and click SYNC button all the records on that client will be sync to the server.
View 2 RepliesI have a little problem with application setting in VB.net 2008. I want to switch main server and backup server connection string with combobox. [Code] It did change the Application Setting connection string in the main form when combobox1 was changed. But the problem comes, when child form was called. On the child form there is DataGridView with Dataset using application connection string. Even the Backupserver was selected on the main form, child form dataset connection string doesn't change. I don't know how to pass the current connection string to child form dataset although it is set to use application setting.
View 6 RepliesI have a project where I added visually and successfully a datasource of MySql. I binded a datagridview with a table.
But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.
Rather than use an Entry name of an existing VPN connection, is it possible to connect to a remote network by creating a temporary connection on the fly by using the remote IP/Host name, username and password?
View 6 RepliesWhat i have going on, is i have a MySQL connector as a resource on my application, and im basically trying to connect to my MySQL server, to either a) register a new account, or b) check that the account exists and they are premium, and login, Now what i have run into problems with is: My MySQL Database Name has a _ in it which VB is not allowing for some strange reason.
The code i am using is below
Imports MySql.Data.MySqlClient
Public Class Form1
Function UpdateRecord(ByVal query As String) As Integer
[CODE]...
How i can allow the _ into the application, because the only databases that don't have a _ in the user or dbname are a) Paid ones which i DO NOT have the money for or self hosted ones, i cannot leave my computer on 24/7
