Javascript中如何传递“IPictureDisp*”类型的参数？

hugeice 2011-08-17 09:07:42
一个视频播放ActiveX中有如下方法：

[id(DSPID_ADDSUBTITLE), helpstring("Add optional subtitle to control")]
HRESULT AddSubtitle([in] BSTR language, [in] BSTR url, [in] LONG index, [in] IPictureDisp* picture);

在HTML中如下调用，IE报错“类型不匹配”：

imgSubtitleChs = new Image();
imgSubtitleChs.src = "subtitle_chs.jpg";
ax7dliveplayer.AddSubtitle("chs", "chs.srt", 0, imgSubtitleChs);


请问Javascript如何传递一个图片给控件？？控件是用IPictureDisp*还是用别的什么类型的参数才能接收JScript传递的图片？？

谢谢！

谢谢两位 ：）

我已经将参数改为 VARIANT picture，JScript现在可以调用到我的方法了，传递进来的VARIANT是个IDispatch*，但是我不知道如何使用这个IDispatch，用以下代码将类型库中的函数名打出来了，有392个接口函数，但是没有发现能够获取图像数据的方法 ：（

那位能够告诉我如何读取传递进来的Image对象的位图数据？


代码：


STDMETHODIMP Cax7dliveplayer::AddSubtitle(BSTR language, BSTR url, LONG index, VARIANT picture)

{

	if ( VT_DISPATCH == picture.vt ) {

		CComPtr<IDispatch> pIDisp(picture.pdispVal);

		UINT ctinfo = 0;

		HRESULT hr = pIDisp->GetTypeInfoCount(&ctinfo);

		if ( SUCCEEDED(hr) ) {

			CComPtr<ITypeInfo> pITypeInfo;

			hr = pIDisp->GetTypeInfo(0, LANG_NEUTRAL, &pITypeInfo);

			if ( SUCCEEDED(hr) ) {

				TYPEATTR* pta;

				hr = pITypeInfo->GetTypeAttr(&pta);

				if ( SUCCEEDED(hr) ) {

					int fun_num = pta->cFuncs;

					if ( TKIND_DISPATCH == pta->typekind ) {

						for ( int i = 0; i < fun_num; i++ ) {

							FUNCDESC* pfd;

							hr = pITypeInfo->GetFuncDesc(i, &pfd);

							if ( SUCCEEDED(hr) ) {

								/*if ( (pfd->wFuncFlags & (FUNCFLAG_FRESTRICTED | FUNCFLAG_FHIDDEN)) == 0 )*/ {

									CComBSTR bstr_name, bstr_doc;

									hr = pITypeInfo->GetDocumentation(pfd->memid, &bstr_name, &bstr_doc, NULL, NULL);

									if ( SUCCEEDED(hr) ) {

										JTRACE2(JTRACE_INFO, JL_HIGH, _T("Cax7dliveplayer::AddSubtitle: %d: memid = %d, name = \"%s\", help = \"%s\"\n"),

											i, pfd->memid, (LPCTSTR)(_bstr_t)bstr_name, (LPCTSTR)(_bstr_t)bstr_doc);

									}

								}

								pITypeInfo->ReleaseFuncDesc(pfd);

							}

						}

						JTRACE2(JTRACE_INFO, JL_MEDIUM, _T("Cax7dliveplayer::AddSubtitle: ok!\n"));

					}

					pITypeInfo->ReleaseTypeAttr(pta);

				}

			}

		}

	}

	return S_FALSE;

｝

看上去是这个 AddSubtitle() 的定义不够科学，对脚本语言不友好，如果定义为 IDispatch *picture 就好多了。

哈哈，又学到新东西了！这个 Image ……

居然真是一个“内置”对象，但奇怪的是竟然查不到关于它的任何资料，我真是笨死了 :(

试了一下，感觉它很像是 <IMG> 对象（属性集合很接近，tagName 就是 'IMG'），但无法确认它是否跟 <IMG> 完全一样。

其实我总觉得 IHTMLElementRender 挺有希望的……

当然，既然“传入 url”的方式能够被接受，这确实是最简单的方法。

一开始我定义接口参数类型为 IPictureDisp* 只是惯性思维，因为控件的背景属性的类型为 IPictureDisp*，于是我就想当然的以为Javascript传递的图片会是这个类型，但实际情况确实不是这样的！

Image应该是Javascript内置对象，与HTML页面中用<img></img>标签生成的图片对象是一样的，在Javascript中用 new Image；的方式来加载图片可以不显示出来，主要是用来做图片的预加载的。

楼主真是个钻研的人，佩服！

其实主要得看 new Image() 得到的是个什么对象。你最早把接口参数类型定义为 IPictureDisp* picture，是不是说你明确知道得到的是这个类型的对象？但实际情况似乎并不是这样。

所以关键还是看 Image 到底是个什么东西，应该是有源代码的吧？

to [maquan]:

传递进来的IDispatch*接口上查询 IPictureDisp 失败，返回 E_NOINTERFACE；

另外，我用从IDispatch接口上得到ITypeInfo接口获取ITypeLib接口，然后将ITypeLib上所有的接口打印出来了，居然有815个条目，其中包含429个Dispatch接口，和另外71个普通接口，其余的都是组件类和结构体、枚举等的定义。
在那71个普通接口中有个接口IHTMLPainter，差MSDN好像是IE用来渲染对象用的，接口方法“Draw”可以在DC上把对象画出来，可惜在传入的IDispatch接口上查询这个接口也失败了！
倒是有一个接口IHTMLElementRender可以查询到，不过调用“DrawToDC”时失败了，看了以下MSDN，这个接口好像是用来打印的。

然后我把所有的接口上的所有函数名打印出来（有3万多行！！），然后搜索“Draw”和“Render”等关键字，找到的函数也都是属于上面两个接口或类似接口中的函数，无奈只好放弃。


现在用 [akirya] 网友说的传入图片URL的方法，在控件中调用OleLoadPicturePath加载图片，可以直接得到IPicture接口，可以正常工作了。
不过一开始就是因为不想自己在控件中去加载图片才想通过Javascript传进来的，没想到这么困难，在VBScript下有一个函数类似OleLoadPicturePath，可以直接得到一个有IPictureDisp接口的对象，可以直接传递给ActiveX控件，不知道为什么在Javascript下没有对应的东西～～



谢谢各位捧场，结贴 ：）

你传进来的这个 IDispatch 对象，是 IPictureDisp 对象吗？怎么看上去像是个 DOM 对象……

你可以用 QueryInterface 试一下获取 IPictureDisp *，拿到这个指针后面的应该就好办了。
