Is there any way to play MPEG file in vfw (Video for Windows)?

Yeah VFW, just selects the appropiate CODEC for you.

Hi.
I was wondering if there is a way to directly write to a CD-R or CR-RW from a VC program basically treating it like a hard disk or disk drive etc?

There exist expensive SDK's for CDR writing, which would make me presume it's not easily done without them.

Sure you can do it if Direct CD is active.
|
|

I am not too familiar with Direct CD. Is there any where I can get more information?

DirectCD came with the easy CD Creator.... The problem is that you need to prepare the cd, and then you need to decide if you want to leave the cd open or not...

Hi.
I am keeping a array of pointers to CView and CFormView derived classes. I want to access different functions and variables in each class. Because they are specific to each derived class, I need to type cast. I was wondering if there is another way to access the pointer to the class that will automatically access the top (or lowest?) level derived class. By this I mean if CXView is derived from CView and CYView is from CFormView, I can just xx.GetView[1] and it will return the pointer as a CXView or CYView and not Cview because there may be other views derived from CFormView in the array.
I hope I am explaining this right.

I don't know what you're trying to say, but if you use a C++ cast ( dynamic_cast<cxview*>(MyView) ), it will return NULL if it is not an object of that type.

What I mean is I have an array
CView* view[20];
view[0] = ... derived from Cview
view[1] = ... derived from CformView
each view can be a view derived from Cview or Cformview etc. In each of these views, they have functions that I want to access.
So now if I want to access
((CXXView) view[0])->...
or ((CYYView) view[1])->...
I have to type cast it to get to access things.
Is there a way to do things so that it will return the ptr to the relevant derived class so that I do not have to explicitly type cast things?

No. If you *know* that 1 is a YY view and 0 is an XX view, then you can use a blunt cast, but you're safer to use dynamic_cast to be sure. I *always* use it and *always* check the return, even though I presume in most situations it never will. If you have more than one type, why not have more than one array ? The alternative is to create a class that holds the pointer, and calls the methods you want, and internally knows what type it is, then collect those in an array ( a std::vector I hope ).
That's a solution to what you *want* to do, when I think what you *need* to do is chance the design.

Well, I will think about it. The only reason I want to do things this way is because I have a Mainfrm that holds all these views. It is an SDI app with multiple views and one frm and one doc. This way I can bring up the views just by calling the appropraite array with the right index. After that I can call its function I need.
Can you give me an example of a better way to handle this type of situation? Thanks.

It depends - how does your view change, I mean, under what circumstances. How is it that an array index is the logical way to look it up ?
Having had a chance to sleep on it, I think dynamic_cast might be the best way to handle this, because it means you can safely pull the views out and turn them into whatever type of derived view they are. There is no nice way of setting it up so that you don't need to do this.

I'm not quite sure what your problem is, but it sounds kindda like a problem I ran into some time ago. I had a number of views, some derived from CFormView, som directly from CView, that were shown in a multi-view SDI app. I wanted to put some general-purpose functions into all the view, but since all my views were not derived form the same base class I couldn't use the old fashion OOP solution. I used a trick described somewhere (I'll get back to that later) that used templates to "add" functionality to existing classes. Basically, instead of defining the common functions in a base class they were added to the top-level classes by the template. If this is what you want, read on. If not, sorry for wasting your time 
I haven't got the information at hand right now, but I can find it if you want. I think it was a series of papers on CodeGuru on a totally different subject (that was back when CodeGuru still contained something interesting - but then all the Gods (Chris, Tom Archer etc) moved to CP, and so did I). It is not an easy solutions, you need to modify the messagemap macros and use an implementation base class to avoid code bloat, but it works nicely once it's set up. I even put the stuff in a DLL which only complicates it further...

I am a VC beginner.These days i met a trouble:i can't successfully open a AVI clip(the Open function returns always '0').My steps as the following:import a avi file using resource editor->select a animate ctrl and paste it onto the dialog template,and set it to auto play->add a member variable(type control),corresponded to the ctrl in the dialog->open(UID) it in InitDialog().
is there something important i missed or wrong? 
God blessing me...

I have read in a book that it isn't a good way to create a vector with CAsynchSocket varibles to make a server to handle for example only 3 clients. But isn't it a good way if I don't know multithreading and so and the server is just going to handle 3 clients?
PLEASE ANSWER!!
And if you think that is ok, how can a client send a message to a client?
It must pass the the server, mustn't it? Because a client can't connnect to a client!

In my experience ( four client/server projects deploying winsock 2.0) is to avoid CSocket and CAsyncSocket at all costs!
A basic server implementing *raw* sockets can be coded in more or less 3 hours, that includes the Multithreading side as well. A good book to buy is Programming Winsock 2.0 by Lewis Napper.
Hope this helps.

I need the advice from somebody who already made software product using Microsoft Speech SDK. I want to implement simplest command recognition. After trying the SDK samples and writing small prototype I found that recognition quality seems to be not enough for my product. Now I consider to check out other products such as The Dragon NaturallySpeaking® SDK.
However, Microsoft programming interface is really the best and I can waste a lot of time learning other products and finally get almost same recognition quality.
My question is: are there speech recognition engines significally better than one supplied with Microsoft Speech SDK?
I need only English support for now, and my command dictionary is supposed to contain 20-30 commands.
Any information from developers who already used Microsoft Speech SDK or other product will be helpful to me.
Thank you in advance.

What kind of hardware are you using (microphone), and how much have you trained the engine? Those have a decent effect on the accuracy of the engine.
Peace!

1) Creative VIBRA sound card
2) Andrea DA-400 2.0 Desktop Array Microphone
3) I created my profile using Speech Settings Wizard and set it's sensitivity and accuracy to the values that seem to be optimal.
The program executes my commands, but if I am just talking (event not in English), it sometimes reacts. I consider to turn on microphone only when I make the command, and turn it off after this. I am wondering if any other speech recognition engine has such paranoidal reactions?

Hi All,
Is there any API or Interface to query browser "in which internet zone existing web-page is?" I wanted to do it programmatically. I can see an icon and text get displayed at right-hand-side of status-bar.
Thanks for your suggestions.

There are a lot of information on that in MSDN, so I won't copy it here. Look for interface IInternetZoneManager in MSDN and you'll find all what you need

Sent you by e-mail, by in case some one else want to know that, so below the code that do the work:
USES_CONVERSION;
CString csZone = _T("Unknown");
IInternetSecurityManager *pManager = NULL;
HRESULT hr = CoCreateInstance(CLSID_InternetSecurityManager, NULL, CLSCTX_INPROC_SERVER,
IID_IInternetSecurityManager,(void**)&pManager);
if (hr == S_OK) {
DWORD dwZone;
pManager->MapUrlToZone(T2OLE(lpszURL), &dwZone, 0);
pManager->Release();
switch(dwZone) {
case URLZONE_LOCAL_MACHINE:
csZone = _T("Local");
break;
case URLZONE_INTRANET:
csZone = _T("Local Network");
break;
case URLZONE_TRUSTED:
csZone = _T("Trusted");
break;
case URLZONE_INTERNET:
csZone = _T("Internet");
break;
case URLZONE_UNTRUSTED:
csZone = _T("Untrusted");
break;
default:
csZone = _T("Unknown");
break;
}
}
csZone now contains the name of zone
The lpszURL contains the URL to check
