The input stream.

public : IInputStream InputStream { get; }public IInputStream InputStream { get; }Public ReadOnly Property InputStream As IInputStream// You can use this property in JavaScript.

The output stream.

public : IOutputStream OutputStream { get; }public IOutputStream OutputStream { get; }Public ReadOnly Property OutputStream As IOutputStream// You can use this property in JavaScript.

Creates a CustomDevice object asynchronously for the specified DeviceInformation.Id.

public : static IAsyncOperation<CustomDevice> FromIdAsync(PlatForm::String deviceId, DeviceAccessMode desiredAccess, DeviceSharingMode sharingMode)public static IAsyncOperation<CustomDevice> FromIdAsync(String deviceId, DeviceAccessMode desiredAccess, DeviceSharingMode sharingMode)Public Static Function FromIdAsync(deviceId As String, desiredAccess As DeviceAccessMode, sharingMode As DeviceSharingMode) As IAsyncOperation( Of CustomDevice )// You can use this method in JavaScript.

Gets a device selector.

public : static PlatForm::String GetDeviceSelector(PlatForm::Guid classGuid)public static string GetDeviceSelector(Guid classGuid)Public Static Function GetDeviceSelector(classGuid As Guid) As string// You can use this method in JavaScript.

Sends an IO control code.

public : IAsyncOperation<unsigned int> SendIOControlAsync(IIOControlCode ioControlCode, IBuffer inputBuffer, IBuffer outputBuffer)public IAsyncOperation<uint> SendIOControlAsync(IIOControlCode ioControlCode, IBuffer inputBuffer, IBuffer outputBuffer)Public Function SendIOControlAsync(ioControlCode As IIOControlCode, inputBuffer As IBuffer, outputBuffer As IBuffer) As IAsyncOperation( Of uint )// You can use this method in JavaScript.

Remarks

SendIOControlAsync is like TrySendIOControlAsync, except this method throws an exception if the operation fails. If you want to handle any exceptions that occur during the operation, use the SendIOControlAsync method. If you just want to be notified whether the operation is successful, but not handle any specific exceptions, use TrySendIOControlAsync.

Sends an IO control code. A return value indicates whether the operation succeeded.

public : IAsyncOperation<PlatForm::Boolean> TrySendIOControlAsync(IIOControlCode ioControlCode, IBuffer inputBuffer, IBuffer outputBuffer)public IAsyncOperation<bool> TrySendIOControlAsync(IIOControlCode ioControlCode, IBuffer inputBuffer, IBuffer outputBuffer)Public Function TrySendIOControlAsync(ioControlCode As IIOControlCode, inputBuffer As IBuffer, outputBuffer As IBuffer) As IAsyncOperation( Of bool )// You can use this method in JavaScript.

Remarks

TrySendIOControlAsync is like SendIOControlAsync, except this method doesn't throw an exception if the operation fails. Instead, it returns false. If you want to handle any exceptions that occur during the operation, use the SendIOControlAsync method.
