webbrowser 如何获取iframe框架中的源代码
iframe打开的网页是动态的 期待高手大驾光临！！！ 框架 浏览器 源代码
[解决办法]
C#实现MyIInternetSecurityManager返回同一个getsecurityid即可访问框架页内容以及获取源码等。
c++直接重写MyIInternetSecurityManager::GetSecurityId
STDMETHODIMP MyIInternetSecurityManager::GetSecurityId(LPCWSTR pwszUrl, BYTE *pbSecurityId, DWORD *pcbSecurityId, DWORD_PTR dwReserved)

{

#define MY_SECURITY_DOMAIN "file:"

int cbSecurityDomain = strlen(MY_SECURITY_DOMAIN);


if (*pcbSecurityId >= MAX_SIZE_SECURITY_ID)

{

memset(pbSecurityId, 0, *pcbSecurityId);

strcpy((char*)pbSecurityId, MY_SECURITY_DOMAIN);


// Last 4 bytes are <URLZONE> and then 3 zeros.

pbSecurityId[ cbSecurityDomain + 1 ] = URLZONE_LOCAL_MACHINE;

pbSecurityId[ cbSecurityDomain + 2 ] = 0;

pbSecurityId[ cbSecurityDomain + 3 ] = 0;

pbSecurityId[ cbSecurityDomain + 4 ] = 0;


*pcbSecurityId = (DWORD) cbSecurityDomain + 4; // plus the 4 bytes from above.

}


return S_OK;

}
VB引用internet control和html object libray的支持，即可实现框架内部访问。
Private Function getFrames(ByVal WB As WebBrowser) As Object
Dim pContainer As olelib.IOleContainer
Dim pEnumerator As olelib.IEnumUnknown

Dim pUnk As olelib.IUnknown
Dim pBrowser As SHDocVwCtl.WebBrowser_V1

Set pContainer = WB.Object.Document
If pContainer.EnumObjects(OLECONTF_EMBEDDINGS, pEnumerator) = 0 Then
Set pContainer = Nothing
Do While pEnumerator.Next(1, pUnk) = 0
Set pBrowser = pUnk
If Err.Number = 0 Then
'Print "Frame: " & pBrowser.LocationURL
If pBrowser.LocationURL = "http://www.baidu.com/" Then '可以在这里加条件判断得到指定的frame，基本可以根据url或者innerHTML中的某个关键字符
Set getFrames = pBrowser
Exit Function
End If
End If
Loop
Set pEnumerator = Nothing
End If
End Function
