My Project is developed in Vb and Mysql. Now i got an error"Connection was Successfully established with the server,but then error occured during the login process"

My Db Connection Code is
Public Sub OpenDatabase(ByVal pblnOpen As Boolean)
        If GCon.State = ConnectionState.Open Then GCon.Close()
        GCon.ConnectionString = String.Format("Server={0};user id={1};password={2};database={3};Pooling=false", GstrServerName, GstrDBUser, GstrDBPass, GstrDBName)
        If pblnOpen Then GCon.Open()
    End Sub

Please show the relevant code lines. The error message looks like one generated by your application. So you should be able to locate the relevant code.

If so, you have already some kind of error check. Then get the error code and/or description too and append it to your error message string. Those contain much more details and help solving the problem.

Please use the green 'Improve question' link to add this information. Without that, it is impossible to help.

If the error occurs in the code from the updated question, use a try catch block around GCon.Open() and report the full exception message to get more details about what happened.

But because your message does not seem to be a system error message, it might also occur in code not shown yet.

Check the name and password you are passing using the debugger, and try "UID" and "PWD" instead of "user id" and "password" in your connection string.
