They default to blue and white +// * if you are on a color display. You enable the 3D effect by setting +// * the ZYZGS_3D style flag in the styles field of the control (like +// * any other control). +// * +// * To select your own colors, you can send the ZYZG_SETFGCOLOR and +// * ZYZG_SETBKCOLOR messages to set the foreground (percent done) and +// * background (percent not done) colors. The lParam is the RGB() +// * value--wParam is ignored. +// * +// * In all of the following ZYZG_??? messages, the arguments are +// * WORDS. If you are setting parameters, the value is sent as +// * the wParam (lParam is ignored). If you are getting parameters, +// * the value is returned as a LONG and should be cast to a *signed* +// * integer. +// * +// * To set the depth of the 3D effect (if enabled), you can send the +// * ZYZG_SETBEZELFACE and ZYZG_SETWIDTH3D messages. The bezel face +// * is the flat top on the 3D border--its color will be that of the +// * button-face. The 3D width is the width of the bezel itself; inside +// * and outside. The light color is white, the dark color is gray. +// * Both widths *can* be zero--both default to 2 which looks to me. +// * +// * The range of the control can be set by sending the ZYZG_SETRANGE +// * message to the control. It can be any integer from 1 to 32767. +// * What this specifies is the number of pieces that create a whole. +// * The default is 100. You can get the current range setting by +// * sending the ZYZG_GETRANGE message to the control. +// * +// * The position (number of pieces out of the whole have been used) is +// * set with the ZYZG_SETPOSITION message. It can be any integer from +// * 0 to the current range setting of the control--it will be clipped +// * if the position is out of bounds. The default position is 0. You +// * can get the current position at any time with the ZYZG_GETPOSITION +// * message. +// * +// * You can also set the range using a delta from the current range. +// * This is done by sending the ZYZG_SETDELTAPOS message with wParam +// * set to a _signed_ integer value within the range of the control. +// * +// * The font used for the percentage text can be set using the standard +// * WM_SETFONT message. You can get the current font at any time with +// * the WM_GETFONT message. +// * +// * The orientation can be left to right, right to left, bottom to top, +// * or top to bottom.
