The best way to hit a URL (I don't need a response) in Visual Basic.Net

Question

I am basically sending a URL to control the tilt and pan of an IP camera, so all I need to do is send the request, I am not worried about receiving anything. Currently I am using:

Dim Request As HttpWebRequest = WebRequest.Create("http://xxx.xxx.xxx.xxx/nphControlCamera?Direction=TiltDown&Resolution=320x240&Quality=Standard&RPeriod=0&Size=STD&PresetOperation=Move&Language=3")
Dim Response As HttpWebResponse = Request.GetResponse

My problem here is, if I hit it two or three times it locks up my program. So what am I either doing wrong, or what is the best way to send this URL?

Thanks

Answer 1

Are you returning any response at all from the camera? It seems like your program is waiting for a response and getting nothing.

Answer 2

You might have better luck calling it asynchronously, and preventing the user from sending the request again until the camera gets itself situated?

Basically you'd use BeginGetResponse instead of GetResponse.
