请问如何获取电话状态，如来电，通话中，有未接来电，正常等
有什么事件来捕获吗还是通过注册表能检视到如HKEY_LOCAL_MACHINE\System\State\Phone\status但不知道获取的数值怎么用
谢谢

SN_PHONECALLTALKING_BITMASK 通话中
SN_PHONEMISSEDCALL_BITMASK 有未接来电
SN_PHONEINCOMINGCALL_BITMASK 来电
SN_PHONEROAMING_BITMASK 漫游
SN_PHONERADIOOFF_BITMASK //the phone's radio is turned off.（比方说飞行模式）

正常是指啥？
有什么不懂的可以看snapi.h里面的注释

谢谢大家
const TCHAR c_szPhoneRegistryRootkey[] = TEXT("System\\State");
const TCHAR c_szPhoneRegistrySubkey[] = TEXT("Phone");
const TCHAR c_szPhoneSignalStrength[] = TEXT("Signal Strength"); //信号强度
const TCHAR c_szPhoneIncomingCallerNumber[] = TEXT("Incoming Caller Number"); //来电号码
const TCHAR c_szPhoneStatus[] = TEXT("Status"); //这个status的值该怎么比较呢

掩码参考：http://blog.csdn.net/genezhangbin/archive/2007/02/27/1515751.aspx
我想问这些掩码怎么用
哪些是表示来电，通话中，有未接来电，正常这四种状态？
我用与操作，因为不知道具体对应哪个掩码，还请熟悉的人指点下

Sorry,上面的代码贴错了。

case UM_PHONESTATE_NOTIFY:
RegistryGetDWORD(SN_PHONERADIOPRESENT_ROOT,
SN_PHONERADIOPRESENT_PATH,
SN_PHONERADIOPRESENT_VALUE,
&dwStatus);

使用 TAPI 函数的 Notify

这三个都可以，就看你想怎么notify了：
RegistryNotifyApp
RegistryNotifyCallback
RegistryNotifyWindow

Sample：



#include <snapi.h>

#define UM_PHONESTATE_NOTIFY WM_USER+1000

HREGNOTIFY hNotify = NULL;



LRESULT RegistryNotifyWindowProc(HWND hDlg, UINT msg, UINT wParam, LONG lParam)

{

    LRESULT lRet       = FALSE;

    DWORD   dwStatus;



    switch (msg)

    {

        case WM_CREATE:

            RegistryNotifyWindow(SN_PHONERADIOPRESENT_ROOT, 

                                 SN_PHONERADIOPRESENT_PATH, 

                                 SN_PHONERADIOPRESENT_VALUE, 

                                 hDlg, 

                                 UM_PHONESTATE_NOTIFY, 

                                 0, 

                                 NULL, 

                                 &hNotify);

            lRet = 0;

            break;

        case UM_PHONESTATE_NOTIFY:

            // You can read the full location with the RegistryGetString function.

            RegistryGetString(SN_PHONERADIOPRESENT_ROOT, 

                              SN_PHONERADIOPRESENT_PATH, 

                              SN_PHONERADIOPRESENT_VALUE, 

                              &dwStatus);

            // Add your own processing statements here.

            if (dwStatus && SN_PHONERADIOPRESENT_BITMASK)

            {



            }

            else if (dwStatus && SN_PHONERADIOOFF_BITMASK)

            {

            }

            lRet = TRUE;

            break;

        case WM_DESTROY:

            RegistryCloseNotification(hNotify);

            lRet = 0;

            break;

        // Add your own statements for handling other messages, here.



    return lRet;

}
