Re: How to modify inserted table in CHtmlEditView

Some notes.

1. For some reason two piece BSTR creation & allocation is advised.

2. If your QueryInterfaces ever return "FAILED" you could have a nasty crash on your next call I guess.
So you should be testing them with your HRESULT

3. When doing this stuff I think it makes sense to add a check that the document is truly loaded !! Ouch !! Smile | :)

PS: I have never used CHTMLEditView So I'm just assuming it's the same as the good ol mshtml.dll

The insertion code has nothing to do with the CHtmlEditView. It's just the author of the posts who managed to put a reference to this class in the post header whenever he posted ! Big Grin | :-D

CHtmlEditView is just a MFC CHtmlView-derived class (a simple web browser control wrapper), using one of the latest methods exposed by IE5.5+ (which were earlier available as a separate SDK (the DHTML edit component SDK, now legacy)).

mshtml.dll is the DOM.

How low can you go ?

That's pretty much how you have to do it, although you can make your code way more readable and stable by using either CComPtr<> or #import'ing mshtml.tlb to get the HTML DOM wrapper classes.

Check out An Advanced Windows Hotfix Manager[^], one of the things I do there is generate a report in a <table> using the DOM interfaces.

Does anyone know how to capture IHTMLElementEvent events
(onclick) for CHtmlEditView? I've tried ON_EVENT and ON_EVENT_RELFECT - doesn't work. Need to capture events
for DISPID_HTMLELEMENTEVENTS2_ONCLICK etc.

Must I create a CCmdTarget sub? What and How do i do it.

I'm desparately trying to complete my project - any help
will be GREATLY appreciated

Confused | :confused:

Thanks

Does an IHTMLElementEvent Interface exist ?

Maybe you should be using ...
IHTMLEventObj which you can get to from the IHTMLDocument ?
then use get_event ?
Also if your element has an "ID" it would be easier to track.

[ Actually IHTMLElementEvents ]

All i need do is to capture the onclick ondblclick events for html elements (all have ids)on the CHtmlEditView. I've tried :

DISP_FUNCTION_ID(CtestView, "onclick", DISPID_HTMLELEMENTEVENTS2_ONCLICK,
OnElementClick, VT_BOOL, VTS_VARIANT)

Doesn't work. Tried ON_EVENT etc. Nothing seems to capture the mouse click on the CHtmlEditView in design mode. Any ideas?

Thanks Art

Ok that must be new also ?

I'm a bit out of date with this.

One ugly solution I have used is to monitor the ?? OnStatusTextChange ?? message.

Can you build an app to monitor the events fired from your CHtmlEditView ? And then back track for it ?

One thing you might be ommiting to do is
EnableAutomation();
I'm guessing you would have to do this every time the elements were created. As in a constructor.
This was needed for use with the DISPID_HTMLDOCUMENTEVENTS_ONCLICK, otherwise it wouldn't show up.
Maybe one test you could try is sending a IHTMLElement::click() Command Or whatever it is you use with the EditView to see what message should be fired back out.
Unfortunatly I don't have VC7 to play with so I'm not much help. Frown | :-(

CListCtrl Help

Ken Mazaika1-Nov-02 13:53

1-Nov-02 13:53

I am trying to put a CListCtrl onto a dialog. I checked out Weagle's tutorial which had be end up with this code in the OnInitDialog function:

<br />
	HIMAGELIST hList = ImageList_Create(16, 16, ILC_COLOR8|ILC_MASK, 1, 1);<br />
	m_il.Attach(hList);<br />
	CBitmap cBmp;<br />
	cBmp.LoadBitmap(IDB_FOLDER);<br />
	m_il.Add(&cBmp, RGB(255,0,255));<br />
<br />
	m_listFolder.SetImageList(&m_il, LVSIL_SMALL);<br />
<br />
	LVITEM lvi;<br />
	lvi.mask = LVIF_IMAGE | LVIF_TEXT;<br />
	lvi.iItem = 0;<br />
	lvi.iSubItem = 0;<br />
	lvi.pszText = "Testing";<br />
	lvi.iImage = 0;<br />
	m_listFolder.InsertItem(&lvi);<br />
	<br />

All I want it to do is to display the IDB_FOLDER next to the word "Testing" in the listbox. It compiles fine, but gives a Microsoft Debug Library Error on afxsmn.inl on line 130. Any insight would be appriciated.

So what is it asserting on?

first on:
m_listFolder.SetImageList(&m_il, LVSIL_SMALL);

then on:
m_listFolder.InsertItem(&lvi);

No I mean what condition is failing and causing the assert? An assert checks that come necessary condition is true, and if it is false, then there's a bug in the calling code (yours).

There is no afxsmn.inl file, do you mean afxcmn.inl. If so I'm guessing that you have put your code before the call to CDialog::OnInitDialog();

If this is so, the window for the dialog has not yet been created. Move your code after the CDialog::OnInitDialog(); line.
