windows ce 的开始菜单的子项可以通过更改注册表来更改,但只能对有限的子项进行更改.如果想要对开始菜单进行更为详尽的设置,必须要对代码下手.开始菜单位于"$(_WINCEROOT)/PUBLIC/SHELL/OAK/HPC/EXPLORER/TASKBAR/stmenu.cpp.由于代码众多,再此只对菜单的创建函数StartMenu_Create()做一个注释.下面这个例子的菜单只有"设置"和"程序"两个子项
HMENU StartMenu_Create(VOID)

 if (!hmenuSettings) {

//如果无法创建下级弹出菜单,则跳出此函数
    hmenu = CreatePopupMenu();
 if (!hmenu) {
  FileMenu_Destroy(hmenuSettings);
  return 0;
 }

// 开始菜单
 for (i=0; i<START_NUM_STATIC_ITEMS; i++) {
