IPrinterQueue::SendBidiQuery()

Question

Can someone tell me how to implement this in a C++ Metro app? I need to ultimately query for the \Printer.DeviceInfo:NetworkingInfo.IPAddress.

Thanks

So far....

I've authored a Device Metadata package, and I have the code below. There are 2 problems up to now. The 1st is IPrinterExtensionContext is an "undeclared identifier". What do I need to include to resolve this reference? And the 2nd is, if I comment out the last 2 lines in the try block, the FromDeviceId() call throws a Platform:AccessDeniedException. id="\\?\SWD#PRINTENUM#{F346C2E3-9B77-4833-9742-E16BA238CBC3}#{0ecef634-6ef0-472a-8085-5ad023ecbccd}"

	try
	{
		Platform::String^ id = m_deviceInfo->Id;
		Platform::Object^ printContext = Windows::Devices::Printers::Extensions::PrintExtensionContext::FromDeviceId(id);

		IPrinterExtensionContext^ printerContext = (IPrinterExtensionContext^)printContext;
		printerContext->PrinterQueue->SendBidiQuery("Printer.DeviceInfo:NetworkingInfo.IPAddress");
	}
	catch (Exception^ ex)
	{

	}

Hi Sparksteam,

I have associated a USB connected printer to a Windows Store device app. I have created the meta data and I am able to enumerate the associated device . PrintExtensionContext::FromDeviceId() method throws the same exception(ACCESS_DENIED) for me. Looks like, the issue is similar..Hope you have solved the issue in your case. Could you please share how you solved the issue?
