这是可能吗？感谢。

解决方案

这是一个老问题，但是经常在这里问，所以我会提供我的解决方案。 >

您提供的链接的问题是 EVENT_OBJECT_VALUECHANGE 不是您应该观看的唯一事件，因为还有其他几个事件其可以指示URL改变（诸如改变标签）。因此，我们将观察 EVENT_OBJECT_FOCUS 和 EVENT_OBJECT_VALUECHANGE 之间的所有事件。下面是一个示例：

  HWINEVENTHOOK LHook = 0; 
 
 void CALLBACK WinEventProc（HWINEVENTHOOK hWinEventHook，DWORD event，HWND hwnd，LONG idObject，LONG idChild，DWORD dwEventThread，DWORD dwmsEventTime）{
 IAccessible * pAcc = NULL; 
 VARIANT varChild; 
 HRESULT hr = AccessibleObjectFromEvent（hwnd，idObject，idChild，& pAcc，& varChild）; 
 if（（hr == S_OK）&&（pAcc！= NULL））{
 BSTR bstrName，bstrValue; 
 pAcc-> get_accValue（varChild，& bstrValue）; 
 pAcc-> get_accName（varChild，& bstrName）; 
 
 char className [50]; 
 GetClassName（hwnd，className，50）; 
 
 if（（strcmp（className，Chrome_WidgetWin_1）== 0）&&（wcscmp（bstrName，LAddress and search bar）== 0））{
 printf（URL change：％ls\\\
，bstrValue）
} 
 pAcc-> Release（）; 
} 
} 
 
 void Hook（）{
 if（LHook！= 0）return; 
 CoInitialize（NULL）; 
 LHook = SetWinEventHook（EVENT_OBJECT_FOCUS，EVENT_OBJECT_VALUECHANGE，0，WinEventProc，0，0，WINEVENT_SKIPOWNPROCESS）; 
} 
 
 void Unhook（）{
 if（LHook == 0）return; 
 UnhookWinEvent（LHook）; 
 CoUninitialize（）; 
} 
 
 
 int main（int argc，const char * argv []）{
 MSG msg; 
 Hook（）; 
 
 while（GetMessage（& msg，NULL，0，0））{
 TranslateMessage（& msg）; 
 DispatchMessage（& msg）; 
} 
 
 Unhook（）; 
 
 return 0; 
} 
  

这将报告控制台中的所有Chrome地址栏更改。

I want get the current URL of chrome current version.

It is possible?. thanks.

解决方案

This is an old issue, but it's asked often around here so I'll offer my solution.

The problem with the link you provided is that EVENT_OBJECT_VALUECHANGE is not the only event you should watch, as there are several other events that may indicate a URL change (such as changing a tab). Thus, we will watch all events between EVENT_OBJECT_FOCUS and EVENT_OBJECT_VALUECHANGE. Here's a sample:

HWINEVENTHOOK LHook = 0;

void CALLBACK WinEventProc(HWINEVENTHOOK hWinEventHook, DWORD event, HWND hwnd, LONG idObject, LONG idChild, DWORD dwEventThread, DWORD dwmsEventTime) {
    IAccessible* pAcc = NULL;
    VARIANT varChild;
    HRESULT hr = AccessibleObjectFromEvent(hwnd, idObject, idChild, &pAcc, &varChild);  
    if ((hr == S_OK) && (pAcc != NULL)) {
        BSTR bstrName, bstrValue;
        pAcc->get_accValue(varChild, &bstrValue);
        pAcc->get_accName(varChild, &bstrName);

        char className[50];
        GetClassName(hwnd, className, 50);

        if ((strcmp(className, "Chrome_WidgetWin_1") == 0) && (wcscmp(bstrName, L"Address and search bar") == 0)) {
            printf("URL change: %ls\n", bstrValue)
        }
        pAcc->Release();
    }
}

void Hook() {
    if (LHook != 0) return;
    CoInitialize(NULL);
    LHook = SetWinEventHook(EVENT_OBJECT_FOCUS, EVENT_OBJECT_VALUECHANGE, 0, WinEventProc, 0, 0, WINEVENT_SKIPOWNPROCESS);
}

void Unhook() {
    if (LHook == 0) return;
    UnhookWinEvent(LHook);
    CoUninitialize();
}


int main(int argc, const char* argv[]) {
    MSG msg;
    Hook();

    while (GetMessage(&msg, NULL, 0, 0)) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    Unhook();

    return 0;
}

This will report all the Chrome address bar changes in the console.
