Tracking down exceptions in Visual Studio 2008

If you ever looked at Visual Studio's Output window and saw a "first chance exception" message and a weird error which is not even documented in the MSDN, and you were not patient enough to debug step by step until the line popped up in the Output window again, I have a solution for you. It also applies if you want the Visual Studio debugger to break every time an exception is thrown and/or unhandled by your code.

The secret is Visual Studio's Debug->Exceptions dialog. Here we can check which exceptions to track down, including .NET, native C++, ATL and stuff.

In the particular case of C++ exceptions, for this mechanism to work, certain conditions must be met:

  1. When installing Visual Studio, the C++ runtime was installed
  2. In the C++ project's general properties, "Use of MFC" is set to "Use MFC in a static library" or "Use Standard Windows Library".
  3. In the project's properties, section C/C++->Code Generation, "Runtime Library" is set to "Multi-threade" or "Multi-threaded Debug" (not DLL!).

A million thanks to Eric Haddan from the MSDN forums

VB.NET: Raise base class events from a derived class

Spanish version / Versión en Español Say we: Have a class we want to divide into subclasses The future base class has events The refactoring leads us to the need of raising an event declared in the base class, from a derived class. When we try to do point 3, we will get a compile error saying that a derived class cannot raise events from a base class. To get around this, we add a protected method in the base class which encapsulates the RaiseEvent call, and call that method from the derived class using MyBase. This way: In the base class (parameters as needed): Protected Overridable Sub OnMessageGenerated(ByVal NewSender As Object, ByVal NewMessage As String) RaiseEvent MessageGenerated(NewSender, New MessageEventArgs(NewMessage)) End Sub And in the derived class: 'Do stuff 'Raise base class event MyBase.OnMessageGenerated( Me, "Message" ) 'Do more stuff...

Apache Kafka - I - High level architecture and concepts

Image
Spanish version / Versión en Español First of all, what is Apache Kafka ? An initial definition for it is "a high-throughput distributed messaging system". Breaking this down a bit: High throughput: One of the main goals of Kafka is to process as much messages per unit of time as possible, in a scalable and fault-tolerant way. For example, LinkedIn , which is where Kafka originated, needs to achieve throughputs in the order of 20 million messages per second and 3 GB of data per second. Distributed messaging system: In a generic distributed system , networked computers work together for a common goal. In Kafka's case, that goal is to send data from points A 1 , A 2 , ... A N , to B 1 , B 2 , ... B M . A common benefit of this kind of system, which is crucial to Kafka's success, is horizontal scalability : the ability to handle higher and higher volumes of data by adding nodes to the system (not to be confused with  vertical scalability , whic

Upgrading Lodash from 3.x to 4.x

Spanish version / Versión en Español There are many breaking changes from version 3.x to 4.x; all changes are detailed in the Lodash changelog . There is also a list of deprecated functions , with a regex you can use to detect usages in your code. However, since it is not an exhaustive list, I will list the changes I encountered when performing my own migration, to help anyone undergoing the same process. Direct renames This section includes functions in which only the name changed, i.e. the arguments and return value are the same. 3.x 4.x contains includes first head rest tail invoke invokeMap padLeft padStart padRight padEnd Direct renames if not using thisArg This section includes functions in which the only change is dropping "thisArg". If you are not using it, you can just rename. If you are using thisArg in 3.x, it can be dropped if you are using iteratee to acce
