MSHTML Table Insertion using CHtmlEditView

[User 51754]

Hello - I'm building a product that requires an html wysiwyg editor - I upgraded to Visual C++ .NET (7) to get MFC 7 - with the CHtmlEditView / CHtmlEditDoc classes, only to find that there is no IDM_TABLE command. I also tried inserting using IHTMLDocument2: BSTR str = SysAllocString(L"   "); IHTMLDocument2 *pDoc; long col=0; IDispatch * pDocDisp = NULL; // get the DOM pDocDisp = GetHtmlDocument(); HRESULT h = pDocDisp->QueryInterface( IID_IHTMLDocument2, (void**)&pDoc ); if( h == S_OK ) { IMarkupServices *pMS = NULL; IMarkupPointer *pMkStart = NULL; IMarkupPointer *pMkFinish = NULL; CComPtr pElement; HRESULT hr = pDoc->createElement(L"TABLE", &pElement); pElement->put_outerHTML(str); pDoc->QueryInterface(IID_IMarkupServices, (LPVOID *) &pMS); //pMS->MovePointersToRange( pMS->InsertElement(pElement, pMkStart, pMkFinish); and also tried IHTMLTable / QueryInterface. None worked. If anyone has a solution to my problem I'd be greateful. Thanks. Art Cote Art Cote

IHTMLElement has a function called InsertAdjacentHTML. BTW: I would recommend you to use smart pointers which make life a lot easier, and they also help avoiding memory leaks. Just us it as follows:

IDispatchPtr pDisp = ...
IHTMLDocument2Ptr pDoc(pDisp);
IHTMLElementCollectionPtr pCollection;
pDoc->get_all(&pCollection);
IHTMLElementCollection pAllTables(pCollection->tags(CComVariant("table")));
...

As someone said, insertAdjacentHTML is a fine stuff :

CComQIPtr pHtmlDoc( GetHtmlDocument() );

CComBSTR bstrWhere = "BeforeEnd";
CComBSTR bstrText = ...; // html code to insert

CComPtr pBody;
pHtmlDoc->get_body( &pBody );

pBody->insertAdjacentHTML( (BSTR)bstrWhere, (BSTR)bstrText);

Thanks for the responses. One question - is insertAdjacentHTML feasible for drag drop operation, i.e., a la IDM_TEXTBOX message - simply drops edit box on CHtmlEditView. What I'd ultimately want to do is to be able to insert a table based on parameters entered in dialog, then drop table onto CHtmlEditView. Similar to the DHTMLedit component using IDM_TRIED_INSERTTABLE. Thanks a bunch for responding so quickly. :)

The solution: BSTR bstrText = SysAllocString(L"             "); // TODO: Add your command handler code here IHTMLDocument2 *pDoc; IDispatch * pDocDisp = NULL; pDocDisp = GetHtmlDocument(); HRESULT h = pDocDisp->QueryInterface( IID_IHTMLDocument2, (void**)&pDoc ); BSTR bstrWhere = SysAllocString(L"BeforeEnd"); IHTMLElement *pBody; IHTMLLocation *pLocation; pDoc->get_body( &pBody ); pBody->insertAdjacentHTML( (BSTR)bstrWhere, (BSTR)bstrText); SysFreeString(bstrText); SysFreeString(bstrWhere); pDoc->Release(); pDocDisp->Release(); works fine - putting a table into CHtmlEditView. However how does one access the IHTMLTable interface - when I to get_activeElement I get the body, not the selected table. Thanks. Art

You haven't selected anything here.:confused: I guess you mean you are willing to get a IHTMLTable pointer from the table you have just inserted. That's easy, change your html tags so that you add a <table ...> with a name="mytable" attribute. Then from the document.all collection, you can ask the DOM to retrieve the IHTMLElement whose name is "mytable" : IHTMLElementCollection::item Method HRESULT item( VARIANT name /*VT_BSTR*/, <-- "mytable" VARIANT index, IDispatch** pdisp ); Finally, cast it to IHTMLTable

Oops - I meant to get the only table element on the page- eventually i will setup element selection. The code works - does one need to update the document somehow ?? so the changes to the table are shown? (fragment) pDoc->get_all(&pCollect); pCollect->item(varID,varIdx, &pDocDisp ); pDocDisp->QueryInterface(IID_IHTMLTable, (void**) &pElem); pElem->put_cols(cols); . . . Thanks again... :-D art
