Use Peripherals to Provide Input Data to the Client Application

Data from peripherals is returned to the Pos Application through events.

Add a reference to:Ncr.As.Interfaces.InputManagerInterfaces.dll

using Ncr.Managers.InputManager;

 

// register with the DeviceManager to catch events when input data is available.

deviceManager.DataReceivedEvent += deviceManager_DataReceivedEvent;

 

void deviceManager_DataReceivedEvent(IInputTuple inputData)

{

   // Save the input data received in the input tuple

}

 

 

// create a list to hold all of the valid termination keys for the current

// user prompt.  All input devices identify termination keys in the devicemanager.xml

// file.  These values are key to turning on devices for particular prompts.

Collection<string> validInputTerminators = new Collection<string>();

// The strings Scanner and Msr are used in the devicemanager.xml file.

validInputTerminators.Add("Scanner");

validInputTerminators.Add("Msr");

// Tell the device manager we are looking for input from the list of devices.

deviceManager.StartInputProcess(validInputTerminators);

 

 

// when satisfactory input data has been received, instruct the device manager to quit //prompting for data.

deviceManager.StopInputProcess();
