code UI for Z-Wave device with C# - error, Error in RequestWithNoRepsonse :Error in ITransportLayer: WriteFile fa Options

[WasabiTDi]

Hi,

I am developing an UI front end using C#.NET for a Z-Wave devices/network. I am using the samples application called ZWavePCController as my guildlines. This is my first ever venture into Z-Wave world.

One of the crucial requirement is to pull update information from the a single device (binary switch) on the network every second in a Real-time view. This is where I encountered the following error "Error in RequestWithNoRepsonse :Error in ITransportLayer: WriteFile failed: err: 170." The error occurs when I am using the Timer control in C# to pull information every second to update the switch status. The result is that the application will hang.

Is there a way to gracefully recover from this situation?

I was able to re-create this error with the sample app, ZWavePCController, continuously click the Get Report button.

According to http://en.kioskea.net/faq/sujet-2347-error-codes-in-windows, the error code 170 is "The requested resource is in use." So I may have to look into thread/lock managing.

Any help would be greatly appreciated.

Thanks,

Newbie
