I have asked this question several time but in a different way and have not had any success. Let me try one more time. How can I start a server side script when a channel is selected to stream. I know it has something to do with urlTransfer but I am not completely sure of how to write it and at what location in the brs file to place it so the script is started just before the stream is called. Please don't reply with jus read the sdk or urlTransfer.

The way to make a GET query to a script would be something like

xfer = CreateObject("roUrlTransfer")
xfer.SetMessagePort(port) ' assuming port has already been created
xfer.SetUrl(your_url)
response = xfer.GetToString()

As for where to put it, that depends on how you wrote your code. It would be before you call Play on the video player or video screen you're using.

Excellent, thank you Markn

Is there any type of interface for urlTransfer (like GetToString) that will let the code continue to step without a return value from the script. The server side script does not produce any return information, it will continue to run until it is terminated and it produces no return value to the urlTransfer interface so the next line of code (screen.show ()) does not process. Once I press the play button, the script starts but not until I manually stop the script does the code continue.
Thanks again

AsyncGetToString.

Could you explain why you weren't able to find this in the docs yourself? We want to make the docs as easy to use as possible, and I would have thought that once you were directed to GetToString you would have been able to find AsyncGetToString.

Thank you for you direction you have been most helpful.
If it is the intention to make the docs as easy to use as possible, you may add some examples. Looking up AsyncGetToString in the sdk only describes the interface without showing how it maybe used. What may seem obvious to some may not be so to others. This applies when one uses a tool on a daily basis while another may not.
Thanks again for the help.
