Cool Rolling Clock Control


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
    // you can also set the first two parameters as 
    // text & Bk Color,
    // 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:
    // add here	
So that when the Dialog thrives from minimum, the static will redraw. That's it!

  • Minimized dialog box problem

    Posted by treeam on 11/15/2005 10:14am

    When I minimize the dialog box that I have the clock on and then restore the dialog box to its original size the clock display gets all messed up. I verified the same behavior with the example/demo code provided. Does anyone know how I can fix the problem?

    This is a great way to display the time, I really like it!

    When I am checking your suppied example on Win98. The function start
    is called from the fuction
    gives assertion failed.
    When I debugged the code of function start.It gives assertion at GetClientRect function.
    As line from your code is as
    it gives assertion failed.
    Try to use any alternative GetClientRect or give any solid reason. If it works well the response me at my mail.
