Connecting to remote MySQL

[Gavisht]

My problem is that I'm unable to connect to a database located in a local computer of company, that computer use wamp server (latest version).

Computer 1 has an application in vb.net and its IP address is: 192.168.1.3 and tries to connect to computer 2, which contains the database named "db1", its IP configuration is: 192.168.1.1

In my program I have in a first form, 4 TextBox:
- Server.
- User.
- Password.
- Database.

I installed wamp server on computer 1 and on the Form I typed:
Server = localhost
User = root
Password =
Database = db1

Everything goes well, I'm connected, I'm happy. After I uninstalled wamp server on computer 1. And I open my form and I typed:
Server = 192.168.1.1
User = root
Password =
Database = db1

but nothing goes well, I'm not online. I created a new user in the user table in mysql DB (computer 2) I tried connecting but ANYTHING happens. I then put % instead of localhost but NOTHING works this time. I stopped the firewall and everything is configured perfectly but all in vain. Why it does not works?

In this case you first connect to local mysql server and then run it

After I uninstalled wamp server on computer 1. And I open my form and I typed:
Server = 192.168.1.1
User = root
Password =
Database = db1

but nothing goes well, I'm not online. I created a new user in the user table in mysql DB (computer 2) I tried connecting but ANYTHING happens.

For now you wants to connect to remote server located on computer 2. Is it you who has designed the application? Your application uses native connection or not? And also check if your mysql server computer 2 permits remote connections.

Thank you for the reply. Yes it is me who has designed the application and I am trying to make other changes above. One of the amendments is to connect to remote mysql. Yes I use a native connection and my computer allows remote connections. I am a little confused about all this stuffs.

You will have to change your connection string stringconnection in your program on connection so you use a code for example:

try
            Dim myConnectionString As String
            myConnectionString = "Server=192.168.1.1;Database=db1; UID=root;Password= "
            Dim myConnection As New MySqlConnection(myConnectionString)
            myConnection.Open()
            Dim myselectquery As String = "SELECT * from `minichat`.`user`  WHERE `user`.`login`  = '" & cvalid_selected & "';"
            Dim myCommand As New MySqlCommand(myselectquery,
myConnection)
            Dim myready As MySqlDataReader
            myready = Nothing
            myready = myCommand.ExecuteReader()
            myready.Close()
            myConnection.Close()
        Catch ex As Exception
        End Try

and you will change the config in your wamp on editing log

You will seek 127.0.0.1 or localhost and you will replace it with 192.168.1.1

I found your problem, you work on a root and the user root and default connects local host. Tthe solution is that you create another user

1 - open PHPMYADMIN (click on the wamp notification icon)
2 - a page opens, its the page created in the database
3 - you will click on the "Privileges"
4 - you can see the root user and these settings and can see that root travel locally
5 - you click on the link "Add User"
6 - to fill the form

Username: * you can parametrize your mysql server
It accepts the user "Any user"
Server: * select "Any Server" to allow the pc to connect that server
password: you can keep a password or let it be blank

and for the menu "Database for this user"
chose "Giving privileges passepartout ("%")"

and for "global privileges": check all preferable

click and perform

ultimately change the username and password on your connection string
