I think you need to close the your connection when you finished with it same as for the dataAdapter and try to run the same code again.

>When I click second time I got error Procedure or function "procedure name display" - has too many arguments specified.

You are adding a parameter object each time.

Use MyCommand.Parameters.Clear() method,

MyConnection.ConnectionString = connstring
        MyCommand.Connection = MyConnection
        MyCommand.CommandText = "sp_developer_display"
        MyCommand.CommandType = CommandType.StoredProcedure

        MyCommand.Parameters.Clear()

        Dim param As SqlParameter = New SqlParameter("@developerid", txtdeveloperid.Text)
        Dim disp = New SqlDataAdapter(MyCommand)
        MyCommand.Parameters.Add(param)
        disp.Fill(mydst, "dev_display")
