You can implement a custom resource class and hold the work days and hours information in it.

You can use custom drawing to render the non-working days and hours differently. To use custom drawing you have to assign the appropriate value to the Calendar.CustomDraw property (depending on which part of which view you want to custom draw), then handle the Calendar.Draw event to perform the actual drawing.

To make GetFreePeriod find periods only within the work hours/days of a resource you can create a worker schedule. The worker schedule will be synchronized with your main schedule but in addition to the regular items it will contain items representing the non-working days/hours. This way GetFreePeriod will not return non-working times.

Let me know if this help.
