Pass data from Main VI to HTTP Method VI

Hi guys,

I'm fairly new to Web Service and HTTP.

Can anyone tell me what's a good method to transfer data from my Main VI to the HTTP Method VI? In a project I'm working on, I enqueued 12 bytes of data into a Queue, which is later dequeued at the HTTP Method, which is then transferred over web service.

Is it advisable to use Queue?

Not sure if there is exactly a right answer to this.  What goes for standard LV goes for LV using web services.  You can use named queues, global variables, functional global variables, etc etc.  Queues are a great way to pass data - you know that the main VI is no longer active when the queue throws an error and you can have your app respond with the appropriate http response code.  In a large application that I am building, I have the main app return data via a DVR that is wrapped in an FGV  Works for me.

But, as with all software engineering, there is not exactly one right answer...

Cheers, cirrus
