duilib CWebBrowserUI重写？

小咖啡0120 2014-02-15 02:45:28

触发js函数后，GetIDsOfNames函数没有任何反映，求教



#pragma once

#include "stdafx.h"



class WebBrowserOwn :

	public CWebBrowserUI

{

public:

	WebBrowserOwn(void);

	~WebBrowserOwn(void);

	virtual STDMETHODIMP GetExternal( IDispatch** ppDispatch );



	virtual HRESULT STDMETHODCALLTYPE GetIDsOfNames( __RPC__in REFIID riid, __RPC__in_ecount_full(cNames ) LPOLESTR *rgszNames, UINT cNames, LCID lcid, __RPC__out_ecount_full(cNames) DISPID *rgDispId );



	virtual STDMETHODIMP Invoke( DISPID dispIdMember, REFIID riid, LCID lcid, WORD wFlags, DISPPARAMS *pDispParams, VARIANT *pVarResult, EXCEPINFO *pExcepInfo, UINT *puArgErr );



	void MyMethod();



};



#include "WebBrowserOwn.h"





WebBrowserOwn::WebBrowserOwn(void)

{

}





WebBrowserOwn::~WebBrowserOwn(void)

{

}



STDMETHODIMP WebBrowserOwn::GetExternal( IDispatch** ppDispatch )

{

	*ppDispatch = this;

	return S_OK;

}



HRESULT STDMETHODCALLTYPE WebBrowserOwn::GetIDsOfNames( __RPC__in REFIID riid, __RPC__in_ecount_full(cNames ) LPOLESTR *rgszNames, UINT cNames, LCID lcid, __RPC__out_ecount_full(cNames) DISPID *rgDispId )

{

	//DISP ID 从200开始

	if(_tcscmp(rgszNames[0],_T("MyMethod")) == 0){

		*rgDispId = 200;

		return S_OK;

	}

	return __super::GetIDsOfNames(riid,rgszNames,cNames,lcid,rgDispId);

}



STDMETHODIMP WebBrowserOwn::Invoke( DISPID dispIdMember, REFIID riid, LCID lcid, WORD wFlags, DISPPARAMS *pDispParams, VARIANT *pVarResult, EXCEPINFO *pExcepInfo, UINT *puArgErr )

{

	if ((riid != IID_NULL))

		return E_INVALIDARG;



	switch(dispIdMember)

	{

	case 200:

		MyMethod();

		break;

	}



	return __super::Invoke(dispIdMember,riid,lcid,wFlags,pDispParams,pVarResult,pExcepInfo,puArgErr);

}



void WebBrowserOwn::MyMethod()

{



}





调用函数：



	WebBrowserOwn  * pWebBrowserUI = static_cast<WebBrowserOwn *>(m_pm.FindControl(_T("ie_doc")));

	

		if(  pWebBrowserUI != NULL )  {

			  pWebBrowserUI ->Navigate2(_T("http://localhost:21625/index.aspx")); 

		 }
