CBN_SELCHANGE 选择项改变时产生的消息
CBN_EDITCHANGE 输入改改时产生的消息:
LRESULT CALLBACK WindowProc(
HWND hwnd, // handle to window
UINT uMsg, // WM_COMMAND
WPARAM wParam, // combo box identifier, CBN_EDITCHANGE
LPARAM lParam // handle to combo box (HWND)
);
在WM_COMMAND事件中。选择项改变时，发生通知事件
case 1001://第1个下拉框ID
{
if(HIWORD(wparam)==CBN_SELCHANGE)
{
HWND com1=GetDlgItem(hwnd,1001);
HWND com2=GetDlgItem(hwnd,1002);

SendMessage(com3,CB_SETCURSEL,index,0);
}
}
}
break;
列表框：LISTBOX
单列列表框-样式默认
多列列表框-样式加 LBS_MULTICOLUMN
操作选择与COMBOBOX一样，CB_改为LB_,如：加入项由CB_ADDSTRING改为 LB_ADDSTRING,当选择项改变后WM_COMMAND通知事件:LBN_SELCHANGE。
