What 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
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'm having a problem connecting my DB to a crystal report. I have tried to databinding my DB in MySql but it seems that it cannot produce the data needed but the fields are there..
here is what i have done to my crystal report. i think i have missed something
I am developing an application with VB using the MySQL Connector Net [URL]. Now each time I go to load data in to a datagridview or in to text boxes on a form, I have to provide something along the lines of:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
'Create connection to MySQL Database
Dim conn As New MySqlConnection
Dim myCommand As New MySqlCommand
conn.ConnectionString = MySQLGlobal
[Code] .....
I think it would be better to leave the connection open to the MySQL database while the application is in use. That way I can just continue to execute queries of inserting and updating, without having the delay of the application having to reconnect. Is there a way where I can create some sort of background task in the application that monitors every few seconds that the connection is still active, and if not it tries to reconnect until its reconnected? I am trying to have it so that then I can code it to just do queries, and when the connection breaks - it disables the form until it is reconnected.

So I am able to create a mysql connection. I have been watching tutorials and they tell me to go Project -> Add Reference and click on MySQL.data
However this does not show up anywhere. ( I have installed the Driver though :S)
I have one multi-row INSERT statement (300 or so sets of values) that I would like to commit to the MySQL database in an all-or-nothing fashion. insert into table VALUES
(1, 2, 3),
(4, 5, 6),
(7, 8, 9);
In some cases, a set of values in the command will not meet the criteria of the table (duplicate key, for example). When that happens I do not want any of the previous sets added to the database. I've implemented this with the following code, however, my rollback command doesn't appear to be making a difference. I've used this documentation: http://dev.mysql.com/doc/refman/5.0/es/connector-net-examples-mysqltransaction.html
Dim transaction As MySqlTransaction = sqlConnection.BeginTransaction()
sqlCommand = New MySqlCommand(insertStr, sqlConnection, transaction)
Try
[code]....
I get the DUPLICATE KEY exception thrown, no Rollback Exception thrown, and every set of values up to duplicate key committed to the database.
I've got a vb app that writes data to a remote mysql database.
When I run the app on a client that does not have the mysql connector it crashes (obviously)
How do I programatically check if the connector is installed on the client and throw up a nice error advising to install it - instead of the unhandled exception error - could not load mysql.data etc error?
I can't figure out how to update a field in a MySQL db using MySQL Connector Net 5.2.5. Can anyone show an example code?

I am am currently developing an application using Visual Basic 2005 and I am also using the .NET MySQL Connector. I have noticed that when the MySQL Connector executes a query the application freezes for a bit so I was wondering if it is possible to create another application with textboxes, labels, etc, that will be hidden and will execute these queries, but the main application will be able to read and modify data on the hidden application so that it won't freeze.
View 18 RepliesI'm working on an application in VB.NET that has to connect to a MySQL database and FTP. How secure is it if I used it in an application that I gave to other people. E.g. if I was to let other people use this application would they be able to find out the MySQL and FTP connection details through intercepting packets or something like that? If that's the case how can I work round this? Also, part of my application is an uploader for users to upload files, is FTP secure for that or are there better alternatives ways in doing that? My server is a Windows Server 08 if that makes any difference.

how to connect to a database of another computer in same local network using vb.net? We already enable remote connection in the sql server configuration and also sql browser and we already connected with one another using wireless network. Here is our connection in vb.net

I have written a new app in VB.net as a front end to a mySQL database held on a PC on the LAN running Windows XP. This worked fine for a while. The PC running the mySQL server started locking up (XP errors, not mySQL errors according to the event logs), so I decided to have a go installing Ubuntu to run the mySQL server to see if that was more stable.Ubuntu 11.10 is now installed, and mysql server is also running. I have imported the old sql database files and the mySQL workbench shows all tables are imported successfully.
HOWEVER, I cannot get my VB application to connect to the database now it resides on Ubuntu - just returns "Unable to connect to any of the specified MySQL hosts" when i try to open a connection. I am fairly new to Ubuntu and MySQL, and don't know if the fault lies with the O/S (a firewall config problem perhaps?) or if I need to do something different with mySQL.I can ping the Ubuntu pc from the client pc and vice versa.I have used ufw to open port 3306 on the server The ufw logs do not show any errors when I try to connect from the client pc, so I don't think it's a firewall problem (but could be wrong). I thought it may be something to do with the usernames I use in the connection string, but when I change these (deliberately use the wrong password for example) I get the same message, rather than a username/password error Is anyone else using a client PC running Windows (W7 or XP) to connect to a mySQL database running on a Ubuntu server?
