## AI overview

This week of the ReactOS GSOC project involved implementing a custom CISFBand class, forwarding its methods to CQuickLaunchBand, and testing the implementation in a virtual machine. The author also tested buttons and a toolbar, then introduced PIDLs as data structures that uniquely identify file system objects.

Hey there! Great to see you all in my 4th blogpost of this series. ;) So far, so good!! No blockers and nothing to worry about, and just being around reactos community is pure fun. Coming straight to the point, this week I continued what I had left last time and that was the james band... err.. i mean CISFBand!! XP After forwarding the methods of the built in system CISFBand and testing its integrity within live virtual machine, the next thing to do was to replace this system CISFBand with my own implementation of it.
