Connection To A Remote MySQL Database?
Jun 21, 2010
I'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?

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.

I'm looking into creating a program which will on program opening connect to a remote mysql database, download the data and store the data into a local file (keeping both in sync is the idea).
Getting a connection to the remote database is my first hurdle, and i'm not suceeding, i know i need to read through more info but if i could get this working it would help me tremendously.
I have attempted to connect using the mysql connector, using the server IP and port number ie. 199.002.999.000:3306 but it doesnt connect, it does connect locally ie. localhost but for some reason it won't connect to the remote server.
My other problem is that i cannot control the mysql server, i.e connections allowed remote etc, i think they're just enabled to accept connections from the server.
Is there a way to run a hidden browser script behind the scenes, download and run the file? I've tried looking for possible ways to acheive this, but have come up trumps so far.

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?

So, what I'm trying to do is to connect to a remote database using the MySQL connector. Dim c As New MySqlConnection c.ConnectionString = "Server=" & URL & ";Database=" & "" & ";Uid=root" & ";password =" & "" c.Open()I know the connection string is correct. I can access the phpMyAdmin through a web-browser just fine. For some reason however trying to open the connection throws an exception 'Unable to connect to any of the specified MySQL hosts'. I tried disabling the VS debugging process, as I thought maybe it's blocking my MySQL access for some reason, but no.

I have an issue with my code. The application interacts with a MySQL database on a remote server, I have access to this server. When my app is running the insert into code I m getting this error: "Conversion from string "INSERT INTO phpvms_fsspireps(pil" to type 'Integer' is not valid."
The variable which holds the Inser Into string, during break point debug gives me this: ""INSERT INTO phpvms_fsspireps(pilotid, code, flightnum, depicao, arricao, route, route_details, distance, aircraft, flighttime, flighttime_stamp, landingrate, submitdate, accepted, log, load, fuelused, expenselist, source,

I would like to test a remote connection to a local Sql 2005 Database first thru Hamachi using a small exe that would be set on the client machine to let me know if the connection was successful or not, in the close future the connection would change to be set thru a VPN but for now i would like to accomplish this by using Hamachi software.i want to code the client .NET exe file to connect to the server, Hamachi gives an IP address and hostname once installed on the "server" machine so i wonder how should i include both in the connection string of the client exe file.

how to create modules and consequently how to use them.I need to do a database in mySql from vb.net. I have tried the usual way, that is my connecting to the database at the beginning of each of my class. I want to know if that can be done through modules, as far as i have read about that or some other way like procedures and functions. In that way, it could ease my coding in not having to write the db connection each time.

I'm trying to connect to my MySQL database I have online at (mywebsite.com), however it just hangs for about 30 seconds and says and does nothing.
Dim sConnection As String = "Server=mywebsite.com;Database=mydatabase;Uid=myusername;Pwd=mypassword;"
Dim scConnection As New SqlConnection(sConnection)
Dim scCommand As New SqlCommand("SELECT * FROM mytable WHERE user = @user AND password = @pass", scConnection)

I'm guessing the connection string is wrong, I'm going to try the server as localhost, but in the mean time hopefully someone might see what I might be doing wrong.I'd also like to look into doing it asynchronously, so the UI doesn't freeze,

I have an MS Access 2003 database built that resides on a shared network path at the company I work for.The database works perfectly for users connected directly to the company network.However, when a user tries to open the database while connected remotely to the company network (they can still access the shared path), they receive the following error:The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.At the time that they tried it, they were the only person accessing the database.They tried a local copy as well as a copy on the network shared drive.[code]

We have a VB6 program that uses an ADODB.Connection to establish a database connection and use its execute function to run SQL statements. The connection we have established is to a SQL Server. It has been working fine. Currently, I am trying to change the connection to a MySQL database. I changed the connection string and the connection is ok.
However, when it comes to running the execute function, it returns a runtime error 3246 - connection object cannot be explicitly closed while in a transaction.
I checked the connection.status before calling execute and found that it is open. When I use MySQL's server connections to check the status, I found that there was a connection before and after execute was called.
I encountered this same error whether I used MySQL ODBC 5.1 Driver or MySQL ODBC 3.51 Driver.

I have some software that grabs information from a mysql server. However, users minimize it to the system tray, and leave it idle for hours until using it again.If a user leaves the program idling for about 15 minutes, then goes into the program again to perform a query, it throws a Fatal Error in the mysql, and says 'connection must be valid and open'
The reason is simply because the mysql connection has timed out..I was wondering what the code would be to re-connect to the server IF it has timed out.

I am using VB 2008 Express and have created an application that connects to a SQL database to populate a datagrid.The application is working properly on my computer but will not on others 'remote connection permissions' error.After some googleing I found that the express version is crippled to only work on local machines that use a database.If I purchase Visual Studio 2008 Standard Edition, import and rebuild my application, will my application be able to run properly on other PC's?

I am developing a chat application using online connection to a mysql databbase. But i am facing a problem. After 10 minutes, MySQL closes all the chat connections because of the 600 seconds timeout (has been set by the host service i am using). I don't understand why is that happening cause every piece of my code which needs data from the database opens and closes the connection (i mean that it dosn't maintain the connection after the query's execution). If i .close() and .dispose() the connection, it still appears in mysql at sleep mode (it terminates only if i exit the program).
