wince上能够使用的hook是有限的

最近在研究如果阻止来电通知消息的弹出，尝试了几种方法都不好用：

（1）使用TAPI截获来电，隐藏来电提示框

（2）使用RIL接口截获来电，隐藏来电提示框

（3）使用State and notification broker，隐藏来电提示框

结果：提示框总是要显示一下再隐藏。

今天又调研了一下SetWindowsHookEx 来设置“消息钩子”，这种钩子能够钩住各种消息，它在pc平台上应用的挺多的，在wince上也能使用但没有相关文档。今天发现在wince上似乎只能捕获一些键盘事件，比如VK_TTALK、VK_HOME等等。

wince下只能用三种钩子
#define WH_JOURNALRECORD 0
#define WH_JOURNALPLAYBACK 1
#define WH_KEYBOARD_LL 20

Here   is   an   article   from   Windows   CE   Developers   FAQ   from   CEGadgers.com.   It  
  could   answer   your   question.  
   
  10.9   SetWindowsHookEx   really   does   work,   sort   of.  
   
  If   you   believe   the   Microsoft   documentation,   SetWindowsHookEx   does   not   work  
  under   Windows   CE.   However,   if   you   have   read   this   FAQ   you   know   that  
  SetWindowsHookEx   can   be   found   in   coredll   (2.11   PSPC   and   HPC   Pro   versions  
  only).   The   question   is,   what   does   it   do,   and   is   it   a   full   implementation.  
   
  I   have   been   wanting   to   write   an   ATL   control   that   passes   messages   (like  
  WM_HIBERNATE)   to   VBCE.   One   way   to   do   this   is   to   create   an   ATL   control,  
  implement   a   connection   point,   and   install   a   windows   hook   that   monitors   the  
  message   queue,   and   whenever   a   relevant   message   appears,   fires   an   event   off  
  to   VB.   Unfortunately,   every   combination   of  
   
  gHook   =   SetWindowsHookEx(WH_CALLWNDPROC,   (HOOKPROC)   MyWndProc,   gInstance,  
  0);  
   
  returned   an   error   87   (incorrect   parameter).   Further   searching   through   the   PB  
  header   files   reveals   only   three   hook-related   defines:  
   
  #define   WH_JOURNALRECORD   0  
  #define   WH_JOURNALPLAYBACK   1  
  #define   WH_KEYBOARD_LL   20  
   
  So   I   stopped   using   WH_CALLWNDPROC   and   tried   WH_KEYBOARD_LL,   and   found   that  
  it   worked   quite   well.   I   actually   implemented   a   hook   callback   that   watched  
  for   VK_OFF,   and   when   detected,   waited   2   seconds   before   returning.   Whenever   I  
  pressed   the   power   button   the   device   would   indeed   wait   before   turning   off.   I  
  also   attempted   to   abort   the   power   off   by   returning   a   non-zero   number   from  
  the   hook   callback.   While   this   does   prevent   the   power   button   from   powering  
  off   the   device,   it   also   causes   the   device   to   crash.   Besides,   VK_OFF   is   only  
  generated   when   the   off   button   is   pressed,   and   not   when   a   device   time-out  
  occurs,   so   the   code   was   of   marginal   use.   However,   if   you   need   to   trap   other  
  low-level   keyboard   commands   (ctrl-esc,   etc)   SetWindowsHookEx   might   be   for  
  you.  
   
  While   I   imagine   journal   record   and   playback   are   implemented   as   well,   I   have  
  not   tried   them.  

 

因此，我不能使用这种消息hook来阻止来电提示。那么只能考虑API Hook技术看看。而现在关键是不知道系统是调用什么API来弹出来电提示的。或许cprog.exe仅仅是监听并截获了RIL_NOTIFY_RING消息，然后把Phone - Incoming显示出来？又或者是他调用了某一个API，这个API能够弹出Phone-Incoming对话框。

再试试吧！加油！
