I'm new to using the IE control (MSHTML) and am not sure how to do something. I know it should be possible. Here it is:
If I have an object embedded in an HTML page and I display that page within the IE control, how do I get it programmatically? It has an ID and all of that.
<br />
<!-- DHTML Editing control Object. This will be the body object for the toolbars. --><br />
<object ID="tbContentElement" CLASS="tbContentElement" CLASSID="clsid:2D360201-FFF5-11D1-8D03-00A0C959BC0A" VIEWASTEXT><br />
<param name=Scrollbars value=true><br />
</object><br />
How do I get programmatic access to the tbContentElement object?
Any help, tips, or pointers to articles or whatever are/will be greatly appreciated.
Thanks,
Mike

You must use IHTMLDocument2 interface. You can find some help on msdn.microsoft.com :
http://msdn.microsoft.com/library/default.asp?url=/workshop/browser/mshtml/reference/reference.asp
example of function to retrieve the value of a tag in a html page :
CString YourApp::GetTagValue(LPDISPATCH lpDispatch, CString strTagId)
{
CString strVal = "";
IHTMLDocument2* pHTMLDocument2 = NULL;
if (lpDispatch == NULL)
return "";
HRESULT hr = lpDispatch->QueryInterface(IID_IHTMLDocument2, (LPVOID*)&pHTMLDocument2);
lpDispatch->Release();
if (hr != S_OK)
return "";
IHTMLElementCollection *pElementCollection = NULL;
hr = pHTMLDocument2->get_all(&pElementCollection);
if (hr != S_OK || pElementCollection == NULL)
return "";
long nElt = 0;
if (pElementCollection->get_length(&nElt) != S_OK)
return "";
for (int i=0; i<nelt; i++)
="" {
="" variant="" varindex,="" var2;
="" varindex.vt="VT_UINT;
" varindex.lval="i;
" variantinit(&var2);
=""
="" idispatch*="" pdisp="NULL;
" hr="pElementCollection-">item(varIndex, var2, &pDisp);
if (hr == S_OK && pDisp != NULL)
{
IHTMLElement* pElem = NULL;
hr = pDisp->QueryInterface(IID_IHTMLElement, (void**)&pElem);
if (hr == S_OK && pElem != NULL)
{
BSTR bstrId = 0, bstrVal = 0;
hr = pElem->get_id(&bstrId);
CString strId(bstrId);
strId.MakeLower();
// Oups, we find our tag !!!
if (strId.Find(strTagId) != -1 && strId != "")
{
// Retrieve all html code
pElem->get_innerHTML(&bstrVal);
strVal = CString(bstrVal);
}
pElem->Release();
}
pDisp->Release();
}
}
pElementCollection->Release();
return strVal;
}
you can use this function like this:
CString strValue = GetTagValue(m_web.GetDocument(), "myid");
With a object embedded in a html page, I think you must use the IHTMLObjectElement interface instead of the IHTMLElement interface.
This is not easy to play with the syntax of theses interfaces, but it works.... Good luck !!!

I have a client that needs to do Powerpoint presentations from his web site.
Does anyone know of any example of this using ASP.NET (C# or VB.NET).
Thanks

Why not just put the ppt file out on the web site and add a link to this file? It will download the ppt and open Powerpoint (or viewer) to display the presentation.

You can always create a property on the select to store the previous value and update it in your onchange handler. EX:
<script language=javascript><br />
<br />
function OnSelectChange() {<br />
var oElem = window.event.srcElement;<br />
var cOrigValue = oElem.LastValue;<br />
var cCurrValue = oElem.value;<br />
<br />
.. do whatever here...<br />
<br />
oElem.LastValue = cCurrValue;<br />
}<br />
<br />
</script><br />
<br />
<select name="MyDropdown" LastValue="" onchange="OnSelectChange()"><br />
<option value="red">Red</option><br />
<option value="white">White</option><br />
<option value="blue">Blue</option><br />
</select>
onwards and upwards...

Not sure about Netscape. We stopped developing for Netscape about 4 years ago. It is a HORRIBLE platform to develop real, functional business apps for.

What version of Netscape?

We are going to be moving from one live web server, to 3 forming a web farm in the next month or so. We'll be using SQL and cookies to track sessions, and so far the examples I've looked at look great. However, one thing I'm not too sure of it the Verisign certificates. Obviously I have contacted them for more info, and it's looking very interesting, but I was wondering if anyone has experience of this, and if so, what advice (do's / don'ts ) you give?
Thanks

I would, if you can ! get your own certificate server (Netscape).
You can request your certs from the MMC within IIS (if you are using IIS) and go to town
The cipher strength can be whatever 40bit, 128bit etc.
This will insure the protection of the packets being routed and the whole nine yards.
My employer considred VeriSign but decided it was too much of a hassle, not to mention the overhead.

Do you know of a good on-line tutorial on this subject. I have been planning on a SSL gatway on my web server but it is all new to me, have not done anything with SSL/HTTPS before.

Hi,
I was just wondering - have you set one of your machines up to be a certificate server then? I know this is possible using Win 2000, but then who is backing you up as it were, to prove you are who you say you are?
Thanks
