Hi all,
I hope that i posted my question in the right place 
I would like to know, if there is some examples or courses to create a little application using RTP in order to visualise my webcam video throught the browser. (on localhost host or network)
I'm using VS2005 + DirectShow.
Thank you.

well.. one option is to develop it as an activex control, and use in browser. You may first make it as a stand alone application to refine the working, then convert it as activex. Google for samples, you will get like this.

ok ...
Do u mean that i have to create an activex probably a one for capturing frames and then add the activex to the browser or what exactly?$
I'm new to DirectShow and i'aint a wed developper.
could u explain more plz ?

yes, exactly. Using Directshow is easy to learn, and you shouldn't be a web developer to develop and test an activex control.
|
|
|
|
|
but how could i add an activex to a web page browser ?

I saw these lines in an example code. I am not clear about it.
CListVieiw::OnInitialUpdate();
CListCtrl & theCtrl = GetListCtrl();
My questions are
(1) Is GetListCtrl()( on the second line) a member function;Which class does it belong to?
(2) what does the '&' mean at the left hand side?

Thank you DavidCrow for your reply.
I wonder what exactly is the role of GetListCtrl(); generate a instance of ListCtrl? or sth else?

To get a reference to the list control associated with the view.

Thanks again.
However, what if there are more than one list controls associated with the view.

Then you'd have more than one view.

You mean ONLY one ListCtrl can be associated with one view?
If so, Why there may be more than one ListCtrl in a dialog
Or, I misunderstand the view concept. I think a dialog essentially is a view.

Yes, unless the view is a CFormView.
cy163@hotmail.com wrote: If so, Why there may be more than one ListCtrl in a dialog
Because a dialog is not a view.

Perhaps. But, have no fear, there's plenty of online documentation/examples to help you out.

If a view is drived from CFormView. How to distinguish between ListCtrls associated with it.
|
|
|
|

They each have a unique control ID, and thus a separate instance of CListCtrl.

So, for a view derived from a non CFormView, GetListCtrl is used to get the reference of the ListCtrl associated with it.
for a view derived from a CFormView, how to get the references of ListCtrls associated with it. What command should be used.

Specifically, a CListView.

Like a dialog, each control has a unique ID and its own control variable (e.g., CListCtrl).

I am using VC 6.0. I would like to create a CFormView based project by using ClassWizard, so that I can see the following line in the CxxxxView class.
Class CxxxxView:CFormView
{
....
....
}
Please tell me how to do this using ClassWizard,
Thanks

The base view class to be used can be selected from the second last page I guess.
Click on your view class and select its base class.
The default is CView.

Thanks you superman for your reply.
Another question concerns the following code snippet. I wonder why
CListView::OnInitialUpdate();
can be called directly, without declaring an instance of the class CListView.
void CMyListView::OnInitialUpdate()
{
CListView::OnInitialUpdate();
ASSERT(GetStyle() & LVS_REPORT);
CListCtrl& theCtrl = GetListCtrl();
theCtrl.InsertColumn(0, _T("Player Name"), LVCFMT_LEFT);
LVCOLUMN col;
col.mask = LVCF_FMT | LVCF_TEXT;
col.pszText = _T("Jersey Number");
col.fmt = LVCFMT_LEFT;
theCtrl.InsertColumn(1, &col);

CListView is the base class of CMyListView.
The object already existing is made of both these classes and of course the other base classes.
So creating another object will not effect the current object.
Also, this is the way the overridden derived class function calls the base class function.

CListView::OnInitialUpdate();
is equals this->CListView::OnInitialUpdate();
CMyListView is derived from CListView. It can derives base class's function {public, protected}.
OnInitialUpdate is the virtual function. CListView::OnInitialUpdate() means call the base class 's function OnInitialUpdate() .
I think that you should read <<c++ primary="">> <<mfc programming="">> firstly.
