Command Line Applications with Visual Studio 2008 and C++

From time to time the need arises for me to create a command line application for Windows using Visual Studio 2008.  Lately I keep forgetting the same thing for my project and when I copy the application over to another Windows machine that doesn’t have VS2008 installed, I run into the following error “The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log for more details.”. Unfortuantly what I fail to remember is that by default VS2008 wants me to create managed code.

Virtualization on any platform with VirtualBox

In my day to day work, I need to have access to multiple operating systems in order to test various things.  Unfortunatly running multiple desktops gets warm and traveling with multiple laptops gets cumbersome.  I serached out and tried various virtualization technologies that would address my problems.  In the end, after testing VMWare, various Xen ( Xen was purchased by Citrix ) incarnations, I finally settled on VirtualBox. Virtualbox was created and sold by Innotek. Sun eventually bought innotek in February of this year.  VirtualBox allows you to install the software on a base system (called the “host”) and within the software you create multiple virtual computers with different operating systems (called “guests”).
