VS 2010 - MySQL Connector As A Resource On My Application - Connect To My MySQL Server
Jun 21, 2012
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'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'm connecting to my mysql server using ODBC in vb.net, the database is shared throughout the company because it is used in an accounting program (simply accounting), each user has their own account user/pass to login to the database. I have developped a program that uses the accounting database and combines it with other information, my problem is that at least once a day I get this error when I run my program: "(10061) ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on"and the error persists for at least 4 hours, for some reason it starts to work again later on in the day.

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,

And this is my code.
Dim conn As MySqlConnection
Dim cnString As String
cnString = My.Settings.constr
[code]...
the DB spec:
Total DB size: 190,1 MB
Total Tables: 106
and the table specs. The titles are in Greek but I think you can understand it from the data. [url]

I'm having a problem connecting to a MySQL server over two different trusted domains.We're developing an app for internal use and have been using MySQL till now. It's a desktop app written in vb.net.Up until now all the users were on the same domain and there were no issues. Just recently there was an higher-level decision to split users in 2 different domains for various reasons.The problem is that users from the new domain cannot access the server. If that helps, I was told by the administrators that the users from both domains are trusted. Both machines are running Windows Server - 2003 and 2008.The server port is open, the grants are all in there(base_class@%) but upon attempt access denied for user base_class@datablock2.

We have a VB.Net application which works fine in our tests in different Windows XP SP3 machines. However there is one machine in which is displaying this error:
Unable to connect to any of the specified MySQL hosts
Using the mysql command, we can successfully connect to the database. We already checked for any other application or firewall that could be blocking the connection but it seems fine. We also reinstalled the system (no errors during the installation) but the MySQL error message doesn't change.
The system settings are exactly the same as in the other computers. We are using "localhost" as server in the connection string. The "hosts" file has its default values (nothing strange in there).

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.

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 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.

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.

I have a programmer who is using VB and LINQ; and I have a MySQL database that is running on a linux server. My programmer tells me that:he cannot connect to the MySQL database via LINQ if he was able to connect then it would require all sorts of rewriting I don't know anything about LINQ but I thought it was an ORM. As such, any DB server that is supported should work just fine? Right? OK, so maybe it's not an ORM... maybe it should generically connect to ODBC and render similar results?

I'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.

I'm using the latest version of the MYSQL DotNet Connector (currently 6.3.7) and I am unable to connect to my database at all with it. It keeps giving me an error. I can connect the the database using SQLyog with the exact same information but not with this.
This is the error:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond Here is the code I'm using:
