 540 // *
 541 // *  DESCRIPTION:
 542 // *      Yet another 'Gas Gauge Custom Control.'  This control gives you
 543 // *      a 'progress bar' class (named zYzGauge) for use in your applications.
 544 // *      You can set the range, position, font, color, orientation, and 3d
 545 // *      effect of the gauge by sending messages to the control.
 546 // *
 547 // *      Before you can use this control, you MUST first export the window
 548 // *      procedure for the control (or define it with the _export keyword):
 549 // *
 550 // *          EXPORTS     gaugeWndProc
 551 // *
 552 // *      You then need initialize the class before you use it:
 553 // *
 554 // *          if (!gaugeInit(hInstance))
 555 // *              die a horrible death
 556 // *          else
 557 // *              you are good to go
 558 // *
 559 // *      The colors used by the control default to black and white if you
 560 // *      are running on a mono-display.  They default to blue and white
 561 // *      if you are on a color display.  You enable the 3D effect by setting
 562 // *      the ZYZGS_3D style flag in the styles field of the control (like
 563 // *      any other control).
 564 // *
 565 // *      To select your own colors, you can send the ZYZG_SETFGCOLOR and
 566 // *      ZYZG_SETBKCOLOR messages to set the foreground (percent done) and
 567 // *      background (percent not done) colors.  The lParam is the RGB()
 568 // *      value--wParam is ignored.
 569 // *
 570 // *      In all of the following ZYZG_??? messages, the arguments are
 571 // *      WORDS.  If you are setting parameters, the value is sent as
 572 // *      the wParam (lParam is ignored).  If you are getting parameters,
 573 // *      the value is returned as a LONG and should be cast to a *signed*
 574 // *      integer.
 575 // *
 576 // *      To set the depth of the 3D effect (if enabled), you can send the
 577 // *      ZYZG_SETBEZELFACE and ZYZG_SETWIDTH3D messages.  The bezel face
 578 // *      is the flat top on the 3D border--its color will be that of the
 579 // *      button-face.  The 3D width is the width of the bezel itself; inside
 580 // *      and outside.  The light color is white, the dark color is gray.
 581 // *      Both widths *can* be zero--both default to 2 which looks to me.
 582 // *
 583 // *      The range of the control can be set by sending the ZYZG_SETRANGE
 584 // *      message to the control.  It can be any integer from 1 to 32767.
 585 // *      What this specifies is the number of pieces that create a whole.
 586 // *      The default is 100.  You can get the current range setting by
 587 // *      sending the ZYZG_GETRANGE message to the control.
 588 // *
 589 // *      The position (number of pieces out of the whole have been used) is
 590 // *      set with the ZYZG_SETPOSITION message.  It can be any integer from
 591 // *      0 to the current range setting of the control--it will be clipped
 592 // *      if the position is out of bounds.  The default position is 0.  You
 593 // *      can get the current position at any time with the ZYZG_GETPOSITION
 594 // *      message.
 595 // *
 596 // *      You can also set the range using a delta from the current range.
 597 // *      This is done by sending the ZYZG_SETDELTAPOS message with wParam
 598 // *      set to a _signed_ integer value within the range of the control.
 599 // *
 600 // *      The font used for the percentage text can be set using the standard
 601 // *      WM_SETFONT message.  You can get the current font at any time with
 602 // *      the WM_GETFONT message.
 603 // *
 604 // *      The orientation can be left to right, right to left, bottom to top,
 605 // *      or top to bottom.  Whatever suits your needs.  You set this by
 606 // *      sending the ZYZG_ORIENTATION message to the control with one of
 607 // *      the following values (default is ZYZG_ORIENT_LEFTTORIGHT):
 608 // *
 609 // *          ZYZG_ORIENT_LEFTTORIGHT (0)
 610 // *          ZYZG_ORIENT_RIGHTTOLEFT (1)
 611 // *          ZYZG_ORIENT_BOTTOMTOTOP (2)
 612 // *          ZYZG_ORIENT_TOPTOBOTTOM (3)

 945 // *  DESCRIPTION:
 946 // *      This is the control's window procedure.  Its purpose is to handle
 947 // *      special messages for this custom control.
 948 // *
 949 // *      The special control messages for the gauge control are:
 950 // *
 951 // *          ZYZG_SETRANGE       :   Sets the range of the gauge.  In other
 952 // *                                  words, the number of parts that make a
 953 // *                                  whole.
 954 // *
 955 // *          ZYZG_GETRANGE       :   Returns the current range of the gauge.
 956 // *
 957 // *          ZYZG_SETORIENTATION :   Sets the orientation of the gauge.  This
 958 // *                                  can be one of the ZYZG_ORIENT_?? msgs.
 959 // *
 960 // *          ZYZG_GETORIENTATION :   Gets the current orientation of the
 961 // *                                  gauge.
 962 // *
 963 // *          ZYZG_SETPOSITION    :   Sets the current position of the gauge.
 964 // *                                  In other words, how many pieces of the
 965 // *                                  whole have been used.
 966 // *
 967 // *          ZYZG_GETPOSITION    :   Gets the current position of the gauge.
 968 // *
 969 // *          ZYZG_SETDELTAPOS    :   Sets the position of the gauge +/- the
 970 // *                                  specified amount.
 971 // *
 972 // *          ZYZG_SETFGCOLOR     :   Sets the foreground (percent done) color.
 973 // *
 974 // *          ZYZG_GETFGCOLOR     :   Gets the foreground (percent done) color.
 975 // *
 976 // *          ZYZG_SETBKCOLOR     :   Sets the background (percent not done)
 977 // *                                  color.
 978 // *
 979 // *          ZYZG_GETBKCOLOR     :   Gets the background (percent not done)
 980 // *                                  color.
 981 // *
 982 // *          WM_SETFONT          :   Sets the font to use for the percentage
 983 // *                                  text of the gauge.
 984 // *
 985 // *          WM_GETFONT          :   Gets the current font in use by the
 986 // *                                  gauge.
 987 // *
