Checking for a Driver Version

Question

Hi All,
I need to check a driver version I have asked this on MSDN & The Code Project and each time got answers that I don't really understand.  I want to check the version of a driver installed if it is not there install it, if it is there which version if it later than the version I am using leave it, if not update it.
I have so far managed to get the below code:
ServiceController[] scDevices = ServiceController.GetDevices();
private void button1_Click(object sender, EventArgs e)         {             MessageBox.Show("Device driver services on the local computer");
foreach (ServiceController scTemp in scDevices)             {                 lstDrivers.Items.Add(scTemp.ServiceType + "," + scTemp.ServiceName + "," + scTemp.DisplayName);                                       }
}
This puts into a list box all the drivers installed on the machine I can see the driver I want and that appears to be all I can do, the Code Project have supplied a Dictionary based bit of code which I am at a loss on how to populate and use at http://www.codeproject.com/Messages/4299056/Re-Continuation-of-Correct-way-of-doing-installers.aspx > I really want a method that can be run while the program is being is installed and when the program is run to avoid the wheels coming off due to a missing or over written driver.
Thanks
Glenn

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 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!)
