Cool Rolling Clock Control

Overview

This is a Clock control  which is able to roll the digit away as the time elapses,
just like what the oil meter does in the old car.

This is a control derived from the CStatic, it’s inspired by
the code of Mr. Mark Findlay for his "Scrolling credits
dialog". However,

a
lot was rewritten. I only focus on the rolling part of the code, and didn’t
provide the interface of the color (Bk&Text), although providing 

those
stuff looks like more professional. But that would be easy for you guys 
if you like, as well as the font. 🙂

Using the Rolling Clock Control

1. Insert the file RollingClk.h
   and RollingClk.cpp into your project
2. Create a dialog in your project. Drag a static control from the control
   panel; setting it to a reasonable size;
3. In the dialog’s header file, add the following line

   // I supposed that you add the file to the same path of 
   // the project, or you have to 
   #include "rollingClk.h"
   
   //include the whole path
   ...
   
   CRollingClk m_Static;
   

4. In the OnInitDialog() of your Dialog class, add the following code

   // the "IDC_STATIC1" is the ID of your static control
   m_Static.SubclassDigItem(IDC_STATIC1,this);
   
   // you can also set the first two parameters as 
   // text & Bk Color,
   m_Static.Start();
   
   // and the third as the slipping speed, or nothing--it 
   // will choose the default values.
   And In the OnPaint() of Parent Dialog, you should add:
   else
   {
   ...
   // add here	
   m_Static.SetFirstTime(TRUE);
   CDialog::OnPaint();
   

So that when the Dialog thrives from minimum, the static will redraw. That’s it!
