Console: Enable the ultrasonic detection capability of Kodak scanner.

[Alex]

Kodak scanners have many custom capabilities. Detailed information about all custom capabilities of Kodak scanners can be get from Kodak TWAIN Integrator Kit: http://www.kodakalaris.com/en/b2b/commo ... tion/twain.

Here is example that shows how to enable the ultrasonic detection capability of Kodak scanner:

Code: Select all

using System;

namespace ConsoleApplication1
{
    class Program
    {

        static void Main(string[] args)
        {

                using (Vintasoft.Twain.DeviceManager deviceManager =
                    new Vintasoft.Twain.DeviceManager())
                {
                    // open the device manager
                    deviceManager.Open();

                    // select the scanner using the standard device selection dialog
                    deviceManager.ShowDefaultDeviceSelectionDialog();

                    // get reference to the default device
                    Vintasoft.Twain.Device device = deviceManager.DefaultDevice;

                    // open the device
                    device.Open();

                    // if Kodak scanner is used
                    if (device.Info.ProductName.ToUpperInvariant().StartsWith("KODAK"))
