Hi All,

I have managed to get the correct version of the driver I need here is the code to do it!

 private void button5_Click(object sender, EventArgs e)

        {

     

            List<SignedDriver> drivers = GetDriverInfo();

          

            foreach (SignedDriver driver in drivers)

                listBox1.Items.Add(driver.DeviceName+","+driver.DriverDate+","+driver.DriverVersion);

        

        }

        private void button6_Click(object sender, EventArgs e)

        {

            int index = -1;

          

            index = listBox1.FindString("USB Serial Converter,20120410000000.******+***");

            if (index == -1)

            {

                MessageBox.Show(" Driver Not Found ","",MessageBoxButtons.OK,MessageBoxIcon.Error);

            }

            else

            {

                MessageBox.Show("index = " + index.ToString() + " , " + listBox1.Items[index].ToString(),"",MessageBoxButtons.OK,MessageBoxIcon.Information);

                textBox2.Text = listBox1.Items[index].ToString();

            }

        }

        private void button7_Click(object sender, EventArgs e)

        {

            const char Comma = ',';

            string Target;

            string Version_Number = "";

            string output = "";

            int count = 0;

           

            Target = textBox2.Text;

          

            foreach (string subString in Target.Split(Comma))

            {

                output += subString + ";";

                count++;

                if(count == 3)

                {

                    Version_Number = subString;

                    break;

                }

           }

            MessageBox.Show("Version of driver is "+Version_Number,"",MessageBoxButtons.OK,MessageBoxIcon.Information);

        }

       

    }

 That took a lot of doing to find out the how and why, the Service Controller method will not allow the info I needed (I hope!)
