也是关于VB的,不知道对你们有没有用处.是我下的.

*                   the button was re-drawn as if it was pushed again.       *
*                                                                            *
*                   For any of the above activities.......                   *
*                                                                            *
*   HIWORD & BTN_SHIFT     is set if this activity involves the right mouse  *
*                          button, or else it is clear.                      *
*   HIWORD & BTN_DBLCLICK  is set means that this mouse button down activity *
*                          is really a double click (if you care).           *
*                                                                            *
*           If you are a custom button, you can also receive this message... *
*                                                                            *
*   HIWORD & BTN_REPEAT    is set means that the button or key is being held *
*                          down, and you are being sent many down messages   *
*                          in a row.  The first such message is sent with    *
*                          this flag clear, all others have this flag set.   *
*                          If you are a custom button, you will have to      *
*                          ignore messages that are repeats if you don't     *
*                          want to get many down messages in a row.          *
*                                                                            *
*                                                                            *
*                    toolbarStringFromIndex(hwnd, index)                     *
*                                                                            *
*                    will return you the string resource ID you gave when    *
*                    you registered this button.                             *
*                                                                            *
*                                                                            *
*  IMPORTANT !!!!!!!!!!!!!!!!!!!                                             *
*  =============================                                             *
*                                                                            *
*  When you get the state of a button, it's already been changed by the      *
*  activity so it's the NEW STATE!!!!!!!!!                                   *
*                                                                            *
*   EXCEPT!!!   for a custom button!  For a custom button, NOTHING WILL      *
*   happen, you have to do it all yourself!!!! So the state is going to be   *
*   the state BEFORE the activity and you have to call                       *
*   toolbarModifyState(hwnd, buttonID, newState) to change the state         *
*   yourself!!!!                                                             *
*                                                                            *
*   You also have toolbarGetNumButtons(hwnd) to tell you how many are on the *
*   the toolbar.                                                             *
*   And... you have other routines you can use if you really want.           *
*                                                                            *
*   ENJOY!!                                                                  *
*                                                                            *
*  P.S.  Don't forget to pass on WM_SYSCOLORCHANGE msgs to each toolbar.     *
*                                                                            *
