This Microsoft Visual Studio 6 add-in is designed to make life a little easier when performing code commenting tasks. It caters for generation of function header comment blocks as well as allowing quick and easy commenting or uncommenting of variables, whole lines of code and multiple lines of code. You can also mark whole sections of your code as applicable to a specific build type. The download is a fully-functional, 30-day trial which can be unlocked after paying the (very small) registration fee which also entitles you to free updates.
