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.
[Code]...
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

View 3 RepliesSo, 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.

View 5 RepliesI downloaded the free Visual Basic Express Edition to create an application that connects to a Mysql database. I searched for the connection string and found a bunch of different ones.I have no idea which one should I use with Visual Basic Express Edition.

i am semester 2 in the "system information", as usual just like in semester 1, this hardcore lecturer just has some way to make us difficult he is giving us a one semester long assignment, and as you probably can see.i got mysql as my database to making a hotel system application.
1.now i am stuck with how to connect "crystal report" with mysql database table??
2.after connected, how shoud i display it?.
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?
View 2 RepliesI 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 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.
View 1 RepliesWe 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 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."

View 2 RepliesI 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.
View 2 RepliesI'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.
