Introduction

This article explains an MS Outlook-style mini-calendar control using WTL.

This began as a port of Matt Gullett's MS Outlook-style miniature calendar control written for MFC. There are still some features remaining to be added to it, but it serves as a reasonable starting point for anyone needing this functionality in a WTL application.

Features

• Display months in n-columns by m-rows
• Single-date or date-range selection (including SHIFT-extended selection)
• Different fonts for: header, day initials, and day numbers
• Auto-repeat on scroll arrows
• Auto-scroll when previous/following months' days are selected
• Callback (via WM_NOTIFY) for highlighting 'special days'
• Month-year selection from header popup (with drop shadow under XP)

Optional display styles include:

• 3D border
• Today's date highlighted
• Previous/following months' days displayed with the months' days
• Week can start on any day of the week

Environment

This control was developed using VC++ .NET, WTL 7, and the Feb 2003 Platform SDK. It has been tested under Windows XP only.
