  9. *  This module allows the caller to select a color.                         *
  10. *  SelectColor() function accepts three parameters:                         *
  11. *   hParent      : handle to the window                                     *
  12. *                  When dialog is finished hParent is activated.            *
  13. *   pColor       : pointer to the LONG variable. If the dialog terminates   *
  14. *                  with an OK message pColor variable will be set to the    *
  15. *                  selected color value, otherwise the pColor remains       *
  16. *                  unchanged.                                               *
  17. *   applyMessage : a message to be sent to the parent window in order to    *
  18. *                  notify about font change. If set to 0 no notification    *                                                                           *
  19. *                  takes place, otherwise a message :                       *
  20. *                    Send(hParent,WM_COMMAND,applyMessage,0L);              *
  21. *                  will be executed each time user changes a color.         *
  22. *                  Sending notification disables a Cancel button.           * 
  23. *  SelectColor returns one of following codes:                              *
  24. *                                                                           *
  25. *    -1      : Insufficient memory to create the dialog box.                *
  26. *     1      : A new color was accepted by the user. The pColor variable    *
  27. *              is updated.                                                  *
  28. *     2      : The dialog was  canceled by the user. The pColor variable    *
  29. *              remains unchanged.                                           *
  30. *     3      : The Color Selector was "busy". Since a Color Selector is NOT *
  31. *              reentrant it can't be used simultaneously with two windows.  *
  32. *              A second invocation will display a message box with the      *
  33. *              information on which application is using a Color Selector,  *
  34. *              when dissmised it will return 3.                             *
