如何获得CDHtmlDialog中Internet Explorer_Server窗口句柄？

Question

MSDN的列子 获得的是Internet Explorer_Server窗口 的父窗口的父窗口的句柄 不是我想要的。
IServiceProvider* pServiceProvider = NULL;
if (SUCCEEDED(pWebBrowser2->QueryInterface(
                    IID_IServiceProvider, 
                    (void**)&pServiceProvider)))
{
    IOleWindow* pWindow = NULL;
    if (SUCCEEDED(pServiceProvider->QueryService(
                    SID_SShellBrowser, 
                    IID_IOleWindow,
                    (void**)&pWindow)))
    {
        HWND hwndBrowser = NULL;
        if (SUCCEEDED(pWindow->GetWindow(&hwndBrowser)))
        {
            // hwndBrowser is the handle of TabWindowClass
        }        pWindow->Release();
    }
 
    pServiceProvider->Release();
} 
通过CDHtmlDialog成员变量m_pBrowserApp->get_HWND()结果失败。
到底该如何做呢？

Answer 1

EnumChildWindows为什么也找不到呢？EnumChildWindows(this->m_hWnd,EnumChildProc,NULL);
BOOL CALLBACK EnumChildProc(          HWND hwnd,
LPARAM lParam
)
{
TCHAR buffer[128];
GetClassName(hwnd,buffer,sizeof(buffer)/sizeof(TCHAR));
if(0 == strcmp(buffer,_T("Internet Explorer_Server")))
{
g_pWebDlg->m_hWBCWnd = hwnd;
return FALSE;
}
return TRUE;

Answer 2

成功了！BOOL CALLBACK EnumChildProc( HWND hwnd,LPARAM lParam)
{
TCHAR lpBuf[128];
GetClassName(hwnd,lpBuf,sizeof(lpBuf)/sizeof(TCHAR));
if(_tcscmp(lpBuf,_T("Internet Explorer_Server")) == 0)
{
*((LONG*)lParam) = (LPARAM)hwnd;
return FALSE;
}
return TRUE;
}
IServiceProvider* pServiceProvider = NULL;
if (SUCCEEDED(pWebBrowser2->QueryInterface(
IID_IServiceProvider, 
(void**)&pServiceProvider)))
{
IOleWindow* pWindow = NULL;
if (SUCCEEDED(pServiceProvider->QueryService(
SID_SShellBrowser, 
IID_IOleWindow,
(void**)&pWindow)))
{
HWND hwndBrowser = NULL;
if (SUCCEEDED(pWindow->GetWindow(&hwndBrowser)))
{
LONG lParam = 0;
EnumChildWindows(hwndBrowser,EnumChildProc,(LPARAM)&lParam);
HWND hwndss = (HWND)lParam; // hwndss就是了
int a = 0;
a++;
// hwndBrowser is the handle of TabWindowClass
} pWindow->Release();
} pServiceProvider->Release();
}

楼主 何必去枚举窗口句柄呢
直接在用CDHtmlDialog的句柄FindWindow就可以了
        HWND m_ieHwnd = ::FindWindowEx(GetSafeHwnd(), 0, "Shell Embedding", NULL);

if (m_ieHwnd)
{
m_ieHwnd = ::FindWindowEx(m_ieHwnd, 0, "Shell DocObject View", NULL);
if (m_ieHwnd)
{
m_ieHwnd = ::FindWindowEx(m_ieHwnd, 0, "Internet Explorer_Server", NULL);
}else
m_ieHwnd = NULL;
}

IE 窗口总共三层，用spy++看看就知道了，要取最里面的那个
