• How can I access UDP ports using a web application on the client PC?

  - by Vaibhav

  One of the thing that current Windows application does is that it writes out information to a hardware device via a UDP message. We are considering porting the application to web-based. I checked Silverlight, and that doesn't allow UDP. We don't want to use ActiveX or Java Applets. What are the other options? Thanks. Update - does anyone know if I can use Flash to do this?

• Is there an API or SDK for TomTom satellite navigation devices that would let me access them from Wi

  - by jammycakes

  I was given a TomTom satellite navigation device (XL 30) for Christmas and I've been wondering recently if it is possible to use it as a location sensor for my own programs on my (Windows 7) laptop. Does anyone know if there is a published API which would allow me to do this? More specifically, how can I query it for my current location (latitude, longitude, and, if possible, altitude?)

• Best way to figure out why didReceiveMemoryWarning is always getting called on a UIViewController

  - by wgpubs

  I have a UIViewController and I'm noticing that I've done something to where the didReceiveMemoryWarning method is getting called every time I run it on an actual device. I've run the project with Run Run With Performance Tool Object Allocations (and Leaks also). There are no leaks but I have no idea how to read or understand the "Object Allocations" data that is displayed. So ... How do I read this information and what is/are the best ways to figure out (and resolve) why this is happening? Thanks

• What is a service provider?

  - by Joey

  Sorry if this is a silly question but I am a C developer who just happen to be in a meeting with a bunch of .NET guys and over heard their conversation. They were sketching out a design and constantly talk of service provider, services and spring. Instead of looking silly by asking them, I just decided to post here. BTW, I am doing device driver development (have been for more than 10 years using C) and NEVER heard of service provider.

• Logvat viewer in Eclipse flickers annoyingly

  - by petersohn

  In the logcat viewer in Eclipse, if it is set to filter messages coming from the application I am currently debugging, the list flickers annoyingly. My guess that it reloads the list every time a log message arrives from my device, even if it is not displayed because of the filter. However, it makes reading log messages very hard. Is there any way to counter this bug? Or is there an alternate logcat viewer for Android?

• Is file transfer possible to iPhone 3.0 via Bluetooth or not?

  - by Dimitri Wetzel

  Is it possible to transfer files of a bluetooth device, lets say a digital pen (e.g. Nokia or Logitech io2) to the iPhone? I am interested if I could do a native application that could somehow get that binary file sent by the digital pen and do something with it. I am used to rfcomm and obex but I can only find inconclusive results when I search for that and the support in the iPhone SDK... Any ideas?
