Maybe it's possible somehow to instruct my linker to use only necessary elements from boost, not all of them? Thanks.

• ConcurrenctBag(Of MyType) Vs List(Of MyType)

  - by Ben

  What is the advantage of using a ConcurrentBag(Of MyType) against just using a List(Of MyType)? The MSDN page on the CB (http://msdn.microsoft.com/en-us/library/dd381779(v=VS.100).aspx) states that ConcurrentBag(Of T) is a thread-safe bag implementation, optimized for scenarios where the same thread will be both producing and consuming data stored in the bag So what is the advantage? I can understand the advantage of the other collection types in the Concurrency namespace, but this one puzzled me. Thanks.

If I want to let the liba.so be always linked into example, what need I do with armlink options ? Any information is very appreciated ;)

• Is there a way to implement OnReady() callback in Qt4?

  - by lilo

  I want to do something which will access network when a QMainWindow is ready.
