• Is it possible to control Visual Studio exception handling from the debugged code itself?

  - by mark

  Dear ladies and sirs. I am wondering if it is possible to control the Visual Studio exception handling options from the code itself. For instance, I would like to turn off stopping on FCE for a certain piece of code, that generates many FCE, however, I would like it to be active for all the other code. Is it possible to do it from code? Something like this: visualStudio.DoNotStopOnFCE() try { // some code generating many FCE } catch {} visualStudio.StopOnFCE() Thanks.

• Python multithreading, How is it using multiple Cores?

  - by Sabirul Mostofa

  I am running a multithreaded application(Python2.7.3) in a Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz. I thought it would be using only one core but using the "top" command I see that the python processes are constantly changing the core no. Enabling "SHOW THREADS" in the top command shows diffrent thread processes working on different cores. Can anyone please explain this? It is bothering me as I know from theory that multithreading is executed on a single core.

• c# 3.5 class List<int> class initialisation

  - by josephj1989

  I can initialize a List like new List{1,2,3,4,5}; However List does not have a constructor which accepts a single parameter. So I tried to run this through the debugger and it seems to be calling the Add method. So how does the compiler know which method to invoke to add each individual element. This may be a silly question but I am a bit confused. Thanks

• iPhone - nested views & controllers

  - by codemonkey

  Is it possible to have a single iPhone screen with its view loaded from a xib by that screen's UIViewController, but then another UIView within that screen with content loaded from a separate xib file? If so, is it possible to have that nested view's events handled by a separate custom UIViewController subclass from the rest of the screen? If both of these things are possible, are they also advisable?
