Hi, I got my result. I have used this code - 

Hi sunny, i have tried with localhost but same error i am getting. Now i have done some changes - 

Public Function GetDataTableSP(ByVal val1 As String, ByVal val2 As String, ByVal val3 As String) As DataTable


        Dim dtdatatable As New DataTable
        Dim conn As OdbcConnection = New OdbcConnection(ConfigurationManager.ConnectionStrings("teststring").ToString)
        Dim cmd As OdbcCommand = conn.CreateCommand
        cmd.CommandText = "{call SP_Login(_action,_uname,_upassword)}"
        cmd.CommandType = CommandType.StoredProcedure
        cmd.Parameters.AddWithValue("_action", val1)
        cmd.Parameters.AddWithValue("_uname", val2)
        cmd.Parameters.AddWithValue("_upassword", val3)
        conn.Open()
        Dim da As New OdbcDataAdapter(cmd)
        da.Fill(dtdatatable)
        da.Dispose()
        conn.Close()
        Return dtdatatable

CREATE DEFINER=`root`@`localhost` PROCEDURE `SP_Login`(_action varchar(10),
_uname varchar(100),
_upassword varchar(30))
BEGIN

if _action = 'Select' then
/*select * from Regis where UName = _uname and pwd = _upassword;*/
select * from Regis where UName = _uname and pwd = _upassword;
end if;
END

Now i am getting error like -
in this line -- da.Fill(dtdatatable)

User=myUsername;Password=myPassword;Option=3;

Hello Rachayita,

Your code is working just fine, no errors.

Are you getting this error while creating the stored procedure or while executing your code?
