请问如何获取电话状态

[Aeolia_Tao]

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

上面我的代码有点问题，修正一下

#include <snapi.h>
#include <regext.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: 
            RegistryGetDWORD(SN_PHONERADIOPRESENT_ROOT, 
                             SN_PHONERADIOPRESENT_PATH, 
                             SN_PHONERADIOPRESENT_VALUE, 
                             &dwStatus); 

            // Add your own processing statements here.
            if (dwStatus & SN_PHONEMISSEDCALL_BITMASK)
            {
                //有未接电话
            }
            else if (dwStatus & SN_PHONEINCOMINGCALL_BITMASK)
            {
                //有来电
            }
            else if (dwStatus & SN_PHONECALLTALKING_BITMASK)
            {
                //正在通话中
            }
            else            
            {
                //其它
            }
            lRet = TRUE;
            break;
        case WM_DESTROY:
            RegistryCloseNotification(hNotify);
            lRet = 0;
            break;
        // Add your own statements for handling other messages, here.

    return lRet;
}

支持楼上。

[guguqiaqia]

去参考wm 6 sdk 下面的那个RAPI sample

[zxjl0214]

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;
}

使用 TAPI 函数的 Notify

[zxjl0214]

Sorry,上面的代码贴错了。

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

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

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
