i installed visual studio ( full installation)then i got xampp from their site i have mysql and apache running i downloaded the connector from mysql site and i created a simple project to check if i can connect to mysql or not i have made this code so far
Imports System.Data.SqlClient
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Connection As String = "Data source=localhost;user=root;password=;Initial Catalog=test;Integrated Security=true;"
[code]....
im having trouble with an exception though it says {"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"}
how can i get rid of this, is it because i installed mysql 2005 with visual studio 2008? and maybe it runs with xampp's mysql and creates these problems?
I am trying to connect to my remote MySql Database within Visual Studio using the compact framework.
I can successfully add a data source and preview the data within the IDE so assume that the connection is ok regarding Connection strings and remote access.
However, when I attempt to access the data using any run time control I get the following error when the table is loaded using the .fill method.
MySql.Data.MySqlClient.MySqlException was unhandled ErrorCode=-2147467259 Message="Unable to connect to any of the specified MySQL hosts."
I've created an application that inserts data into an MySQL database, I have used xampp on the local machine to make sure that the database worked with the application and that everything worked correctly
now when editing the connection string so that I can connect to a remote machine on my LAN I keep getting an error saying "Unable to connect to any of the specified MySql Hosts"
I've checked all the credentials in the connection strings I.E username, password, database name and the machine address.[code]...
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?
Unable to connect to any of the specified MySQL hosts. My code is as follows:

I have checked and double checked username, password, database name, and server. I am new to using MySQL etc., but I pulled the information directly from my phpMyAdmin.
I create an application in VB.net which connects to MySQL, deployed it to 10 computers. 8 of them worked perfectly, 2 of them gave me the error:Unable to connect to any of the specified MySQL hosts.What was different with those 2 computers? Is there any setting I need to do on the MySQL server itself? Anything I need to change/update on those two computers?
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
I am trying to make a login system mysql try to connect to a mysql database.
Here is my code:
Imports MySql.Data.MySqlClient Public Class LoginForm1 Dim MySqlConnection As MySqlConnection Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click MySqlConnection = New MySqlConnection()
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).
Im building an app to manage PSP contents, and it should connect to my MySQL server on my domain to refresh game info and ratings and so on, but I cant make it connect with MySQL Connector 6.1.

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 am trying to connect to a MYSQL database using VB.NET to handle some simple tasks at a page level. Usually the connections are made to a MYSQL database. I have downloaded a MYSQL-CONNECTOR 6.0.7. How do I reference or add this to my web project so that I can create the connection and use the provided methods?In the unzipped package I download I do not see any dll files so not sure what to do with this ATM, I am used to seeing a bin folder which contains this.
I'm just looking for an answer or idea.I plan to connect vb.net to mysql (which is done) and also the PHP connected to the mysql.But I'm confuse with something.VB.NET is use for offline things (which people will come to store and buy), but PHP is buying / booking online. (You know the airport things right ? customer can directly go to the airport and buy tickets or they can buy tickets from the internet)
For ex :Customer A come to airport and buy a ticket which is only left 1 tickets. Customer B wanted to buy from the internet. Both of them saw there is only left 1 tickets. So, both of them buying. When Customer A buy, the employee click buy at the same time with Customer B.In here, I'm confuse, how to declare which person should get the ticket because they click buy at the same time (server time because PHP and MySQL located to the server and vb.net applciation located to other PC/Machine) ?.
I have a VB.Net application that must connect to online MySql database.I already have a MySql database and I connected to it from VB.net using the MySql connector (new instance and direct connect).All I want to do is to connect to this database via a PHP web service, this will make a fast connection and more users can be connected at the same time.I tried to search for this, and I think that the solution is easy and simple, but I don't know a lot about PHP; how to upload files and connect via Web service Reference in VB.net.I downloaded these files: RemoteMySQLDatasetWS.zip And RemoteMySQLTest.zip. from: http:code.google.c.../downloads/list. which contains ".php" / ".wsdl" / ".dll" files and a VB.Net test solution.I uploaded the files (".php" / ".wsdl" / ".dll") to the FTP manager in the cPanel where I created the database. The problem is, First: I don't know if these files are working.Second: if they are working, I don't know how to accesss these file via HTTP, so I can add the "server.php" address as a web service reference in VB.Net.
Just got a mySql database up and running (about 3 weeks ago) and it's working fine for web pages with PHP, but wanted to see if I could access it from Visual Basic (why not right). So I downloaded whats needed to get the MySqlConnection working and Been looking around online and nothing is very intuitive as to what the problem is. The error message is:
MySql.Data.MySqlClient.MySqlException: Host '192.168.2.184' is not allowed to connect to this MySQL server
