Applying the Office 2007 theme to the Calendar can be accomplished with only a few lines of code. You also have the option to change the base color used in the theme. By default the color will be the same color blue as used in Office 2007.
Start by instantiating a CalendarThemeOffice2007 object.
//Create a new Office 2007 theme object CXTPCalendarThemeOffice2007* pTheme2007 = new CXTPCalendarThemeOffice2007;
Next you can optionally define the base color used in the Office 2007 theme.
//This will give a default "gray" base color pTheme2007->m_clrBaseColor = RGB(22,22,22);
Now apply the new Office 2007 theme to the Calendar.
//Apply the Office 2007 theme to the Calendar GetCalendarCtrl().SetTheme(pTheme2007);
