    Introduction

    This is a simple class to display a gradient fill progress control. It works just like the normal progress control. The main enhancements are that you can define the start and end colors and toggle the percentage caption's visibility. It supports both horizontal and vertical progress control styles. The sample application shows both types of controls on a single dialog-based application.

    The control can be incorporated into a project like any other CProgressCtrl-derived control. Either create the control manually, subclass an existing CProgressCtrl, or use the ClassWizard to DDX_control it. The actual code for the progress control is located in GradientProgressCtrl.h and GradientProgressCtrl.cpp. Most of the work happens in the DrawGradient(...) function, which also uses Keith Rule's CMemDC class. The sample project also uses Chris Maunder's ColourPicker. Both of these classes are included in the sample project and can be downloaded elsewhere at this site.

    It is derived from CProgressCtrl so all standard CProgressCtrl functions are available. Additional functions are listed below.

    Please let me know of any problems or improvements. Thanks and good luck.
