Get selected files in CHtmlView

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

Solution 1

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

Take also a look on IWebBrowser2

Solution 2

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)
