Устройства eSCL

В этом разделе

Диспетчер устройств eSCL позволяет программно получить список устройств. Список устройств можно получить с помощью свойства EsclDeviceManager.Devices. Информацию об открытом устройстве можно получить с помощью свойства EsclDeviceManager.OpenedDevice.

Вот пример, демонстрирующий, как открыть диспетчер устройств eSCL и отобразить информацию обо всех доступных устройствах eSCL:

/// <summary>
/// Opens eSCL device manager and displays information about available local eSCL image scanners.
/// </summary>
void GetEsclDevicesInfo()
{
    // create eSCL device manager
    using (Vintasoft.EsclImageScanning.EsclDeviceManager deviceManager = new Vintasoft.EsclImageScanning.EsclDeviceManager())
    {
        // open device manager
        deviceManager.Open();

        // wait while the eSCL device manager searches for eSCL devices
        System.Threading.Thread.Sleep(deviceManager.DeviceSearchTimeout);
        // get count of eSCL devices
        int deviceCount = deviceManager.Devices.Count;
        if (deviceCount == 0)
        {
            System.Console.WriteLine("Devices are not found.");
            return;
        }

        Vintasoft.EsclImageScanning.EsclDeviceCollection devices = deviceManager.Devices;
        // for each eSCL device
        for (int i = 0; i < devices.Count; i++)
        {
            // output the device name
            System.Console.WriteLine(string.Format("Device '{0}'", devices[i].Name));
        }
    }
}

VB.NET

''' <summary>
''' Opens eSCL device manager and displays information about available local eSCL image scanners.
''' </summary>
Private Sub GetEsclDevicesInfo()
    ' create eSCL device manager
    Using deviceManager As New Vintasoft.EsclImageScanning.EsclDeviceManager()
        ' open device manager
        deviceManager.Open()

        ' wait while the eSCL device manager searches for eSCL devices
        System.Threading.Thread.Sleep(deviceManager.DeviceSearchTimeout)
        ' get count of eSCL devices
        Dim deviceCount As Integer = deviceManager.Devices.Count
        If deviceCount = 0 Then
            System.Console.WriteLine("Devices are not found.")
            Return
        End If

        Dim devices As Vintasoft.EsclImageScanning.EsclDeviceCollection = deviceManager.Devices
        ' for each eSCL device
        For i As Integer = 0 To devices.Count - 1
            ' output the device name
            System.Console.WriteLine(String.Format("Device '{0}'", devices(i).Name))
        Next
    End Using
End Sub
