Windows CE doesn't support four common controls seen under other versions of Windows. The animation control, the drag list control, the hot key control, and, sadly, the rich edit control are all unsupported. Animation would be hard to support given the slower processors often seen running Windows CE. The hot key control is problematic in that keyboard layouts and key labels, standardized on the PC, vary dramatically on the different hardware that runs Windows CE. And the drag list control isn't that big a loss, given the improved power of the report style of the list view control.The rich edit control is another story. Although not formally supported, Riched20.dll is on Windows CE platforms that have Pocket Word. The only supported alternative is the rich ink control supported on the H/PC and Pocket PC. This control provides text and ink input. It also converts Rich Text Format (RTF) and Pocket Word Ink (PWI) files to ASCII text.Windows CE supports fairly completely the common control library seen under other versions of Windows. The date and time picker, month calendar, and command bar are a great help given the target audience of Windows CE devices.Now that both the basic window controls and the common controls have been covered, it's time to look at where they're most often used—dialog boxes. Dialog boxes free you from having to create and maintain controls in a window. Let's see how it's done.
