在CHtmlView中获取所选文件 [英] Get selected files in CHtmlView

问题描述

大家好！



我是一个使用CHtmlView作为查看我的应用程序中的文件夹和文件的基础。



但是，我需要能够在我的应用程序中知道当用户采取某种操作时按下f.ex.按钮时在视图中选择了哪些文件和文件夹。我广泛搜索了这个，但我无法让它工作。我假设我必须使用IDispatch接口，但每当我调用QueryInformation时，我总是得到接口不支持错误，除非我使用IID_IDispatch而不是IID_IHTMLDocument2，但这似乎也不起作用。



例如：



IDispatch * pDisp = this-> GetHtmlDocument（）;



HRESULT hr = pIHtmlDisp-> QueryInterface（IID_IHTMLDocument2，（void **）&pIHTMLDocument2）;



hr返回E_NOINTERFACE



因为我们在文件夹视图中对我有意义我有使用IID_IHTMLDocument2的其他变体，但我一直无法提出解决方案。



希望有人可以提供帮助。



亲切的问候

解决方案

IDispatch * pDisp = this- > GetHtmlDocument（）;

//使用HTML的界面

HRESULT hr = pDisp-> QueryInterface（IID_IHTMLDocument2，（void **）& pIHTMLDocument2） ;



另请参阅 IWebBrowser2

回复的Thx，但这正是我正在做的事情。

当我尝试你发布的代码时，HRESULT返回E_NOINTERFACE。

通过使用Navigate2（CString或PIDL）到文件夹创建视图，似乎没有基础HTMLDocume nt2在视图中。



亲切的问候，

< blockquote>解决方案在于它不是您导航到文件夹视图时获得的HTML文档。



来自其他论坛：



当您查看文件夹和文件时，显示的文档不是HTML文档。它是IShellBrowser或IShellView - 尝试查询那些（如果你得到IShellBrowser，你可以使用QueryActiveShellView获取视图）。



当你得到视图时，查询它IFolderView和调用项目（SVGIO_SELECTION）

Hi everyone!

Im a using CHtmlView as the base for viewing folders and files in my application.

However, I need to be able to know in my application what files and folders are selected in the view when the user takes a certain action (pressing a button f.ex.). I have googled this extensively but I am unable to get it to work. I assume that I have to use the IDispatch interface, but whenever I call QueryInformation I always get "Interface not supported error", unless I use IID_IDispatch instead of IID_IHTMLDocument2, but this doesn't seem to work either.

example:

IDispatch *pDisp = this->GetHtmlDocument();

HRESULT hr = pIHtmlDisp->QueryInterface(IID_IHTMLDocument2, (void**)&pIHTMLDocument2);

hr returns E_NOINTERFACE

Since we are in the folder view it makes sense to me that I have to use some other variation that the IID_IHTMLDocument2, but I have been unable to come up with a solution.

Hope someone can help.

Kind regards

Dark

解决方案

IDispatch *pDisp = this->GetHtmlDocument();
//use the interface of the HTML
HRESULT hr = pDisp->QueryInterface(IID_IHTMLDocument2, (void**)&pIHTMLDocument2);

Take also a look on IWebBrowser2

Thx for the reply but this is exactly what I was doing.
HRESULT returns E_NOINTERFACE when I try the code you posted.
The view is created by using Navigate2(CString or PIDL) to a folder, and it seems there is no underlying HTMLDocument2 in the view.

Kind regards,

Dark

The solution lies in that its not a HTML document you get when you Navigate to a folderview.

From other forum:

"When you view folders and files, the document displayed is not an HTML document. It's either IShellBrowser or IShellView - try querying for those (if you get IShellBrowser, you can obtain the view with QueryActiveShellView).

When you get the view, query it for IFolderView and call Items(SVGIO_SELECTION)
