Eureka! After some input from TCP folks, I finally arrived at the solution to getting, and modifying a table inserted into an CHtmlEditView:
STEP 1:
Get the DHTML document to a IDISPATCH
STEP 2:
Query interface for IID_IHTMLDocument2
STEP 3:
get all elements -> IHTMLDocument2::get_all
into IHTMLElementCollection
STEP 4:
Get the item (in this case a table) based on
the table id (
_variant_t varID = _bstr_t(L"view");
_variant_t varIdx(0);
IDispatch *pDocDisp=NULL;
pCollect->item(varID,varIdx, &pDocDisp );
STEP 5:
Now query the table item
<br />
pDocDisp->QueryInterface(IID_IHTMLTable, (void**)&pTable);<br />
STEP 6:
Now do an insertrow with a IDispatch pointer
and -1 for append to end of table
Then query the IHTMLTableRow interface
<br />
IDispatch *pdispRow=NULL;<br />
IHTMLTableRow *pRow=NULL;<br />
pTable->insertRow ( -1, &pdispRow );<br />
pdispRow->QueryInterface(IID_IHTMLTableRow, (void**)&pRow);<br />
STEP 7:
Next do an IHTMLTableRow::insertCell
with an IDispatch pointer
Then query the IHTMLElement interface to get
pointer tp IHTMLElement
insert a space into the cell
do this for the # of columns you have. in my
example below i am inserting a row in a 3 column
table.
<br />
IDispatch *pDispCell=NULL;<br />
IHTMLElement *pCell=NULL;<br />
pRow->insertCell( -1, &pDispCell ); <br />
pDispCell->QueryInterface(IID_IHTMLElement, (void**)&pCell); <br />
pCell->put_innerText(L" ");<br />
I'm sure there's a better way - this solution isn't
elegant but it works!
[ entire code ]
<br />
IHTMLTable* pTable = NULL;<br />
<br />
IHTMLElementCollection *pCollect=NULL;<br />
<br />
_variant_t varID = _bstr_t(L"view"); <br />
_variant_t varIdx(0);<br />
BSTR tag = SysAllocString(L"0");<br />
long cols = 1;<br />
IHTMLDocument2 *pDoc; <br />
IDispatch * pDocDisp = NULL; <br />
IHTMLTableCaption *pCaption=NULL;<br />
pDocDisp = GetHtmlDocument();<br />
HRESULT h = pDocDisp->QueryInterface( IID_IHTMLDocument2, (void**)&pDoc ); <br />
<br />
pDoc->get_all(&pCollect);<br />
<br />
pCollect->item(varID,varIdx, &pDocDisp );<br />
pDocDisp->QueryInterface(IID_IHTMLTable, (void**)&pTable);<br />
<br />
IDispatch *pdispRow=NULL;<br />
IHTMLTableRow *pRow=NULL;<br />
pTable->insertRow ( -1, &pdispRow );<br />
pdispRow->QueryInterface(IID_IHTMLTableRow, (void**)&pRow);<br />
pRow->put_align(L"Center");<br />
<br />
IDispatch *pDispCell=NULL;<br />
IHTMLElement *pCell=NULL;<br />
pRow->insertCell( -1, &pDispCell ); <br />
pDispCell->QueryInterface(IID_IHTMLElement, (void**)&pCell); <br />
pCell->put_innerText(L" ");<br />
pRow->insertCell( -1, &pDispCell ); <br />
pDispCell->QueryInterface(IID_IHTMLElement, (void**)&pCell);<br />
pCell->put_innerText(L" ");<br />
pRow->insertCell( -1, &pDispCell );<br />
pDispCell->QueryInterface(IID_IHTMLElement, (void**)&pCell);<br />
pCell->put_innerText(L" "); <br />
pDispCell->Release();<br />
pCell->Release();<br />
pdispRow->Release();<br />
pRow->Release();<br />
pTable->refresh();<br />
pCollect->Release();<br />
pTable->Release();<br />
pDoc->Release();<br />
pDocDisp->Release(); <br />
Hope this helps.

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 !! 
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 ! 
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
Thanks
Art

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.

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.

hello all, i am a college student runnin outta options...my class has 3 projects (operating systems, CS416) however as a computer engineer my programming knowledge is next to nothing whereas my computer hardware knowledge is thru the roof. I struggled with the first project and got the lowest grade in the class. Well this is my last semester at this college, and i need to pass this in order to graduate, i tried to work on this second project but i am getting nowhere cuz its just too freakin complicated i have til nov 8th to get it done and am getting nowhere, if you can help at all i would be thoroughly greatful...here is the website...
http://athos.rutgers.edu/~chak/class/cs416/fall02/projects/threads/HW3.html
the username is Chakradhar and the pass is cs416-fall02 (case sensitive)
i beg you for any help you can give me....please....help me or i will not be able to graduate because of this one stupid class!!!

Don't expect us to do your homework. However, if you have specific questions while attempting to solve the problem, then i'm sure someone will help you. You obviously have not exercised all of your options (help from professor, TA's, peers, books) and given this any thought.

itsnot that at all, u dont understand, i have very poor knowledge of C and C++, as an engineer it isnt required till this class, and these professors require a lot of previous knowledge, and are unwilling to teach you, its a catch 22

There are two options here.
1. You didn't do the work. You deserve to fail
2. The classes are inadequate to teach you. This will become apparent to the powers that be, when everyone else also fails.
The class is there for a reason, if you can't do the work, your academic record should not reflect otherwise. That would be dishonest and unfair on those of us who passed fair and square.
In any case, it's a reasonably complex task - are you claiming that you believe someone will write this for you, because we are upset that you won't graduate ?

[XPosted in the XML forum]
Do you know what would cause the construction of a Xerxes DOM parser to die? It seems like this should be valid, but I'm obviously missing something.
DOMParser* pDomParser = new DOMParser();
ASSERT (pDomParser != NULL);
delete pDomParser;
Are we required to derive from DOMParser and override certain methods? Btw, I'm using a prebuilt binary of the XML4C 4.0.0 implementation. A ptr to the API docs would also be much appreciated. Thanks!
