用API获得Internet Explorer_Server类的HTML

　　首先要找到含有Internet Explorer_Server类句柄,

　　HTMLDocumentClass result = (HTMLDocumentClass)documentFromDOM(hWnd.ToInt32());

　　result.activeElement.innerHTML就得到所有HTML

private static IHTMLDocument2 documentFromDOM(int hWnd)

{

IHTMLDocument2 document=null;

int lRes=0;

int lngMsg = NativeMethods.RegisterWindowMessage("WM_HTML_GETOBJECT");

Guid IID_IHTMLDocument = new Guid("626FC520-A41E-11CF-A731-00A0C9082637");

if (lngMsg != 0)

{

NativeMethods.SendMessageTimeout(hWnd, lngMsg, 0, 0, NativeMethods.SMTO_ABORTIFHUNG, 1000, ref lRes);

if (!(bool)(lRes == 0))

{

int hr = NativeMethods.ObjectFromLresult(lRes, ref IID_IHTMLDocument, 0, ref document);

if ((bool)(document == null))

{

MessageBox.Show("No IHTMLDocument Found!", "Warning");

}

}

}

return document;

}
