Thank you . I download the demo, but it does not work too.

we all use Windows SP2 system.

Now i have found a way to achieve my purpose.

Thank you for your reply.

The problem is that not every hosts have the ablity to enume hosts in LAN by using WNet functions. only the one which is a domain administrator have the ability.

so i think the WNet functions do not fit me.

now I have succefully enumed hosts of my LAN by sending ARP request.

but this require to install Ourself protocol driver to send ARP requests(SendARP does not fit).

It worked very good.

Why? Are you getting a runtime error? If so, what?

You may want to change this to:

I'm trying to develop an add-in for Outlook Express, the add-in is supposed to intercept sending mails and (optionally) add attachments to the mail being sent.

I have already done that on Microsoft Outlook using Visual Studio Tools for Office, but I couldn't find any way to do it on Outlook Express.

Help would be greatly appreciated, just point me on the way.

Thanks in advance,

Microsoft dosen't provide any documentation to do this. However keep a watch over msdn [^]. Hope they come with additional interfaces soon.

error C2146

I fixed my earlier problem and found a new one that is easely fixed, but I don't like the fix. It would force useres (of the templates) to code in a way that seems unnatural.

// This generates error C2146
typedef classB<classA<char>> classB_type;

// This compiles with out error
typedef classA<char> classA_type;
typedef classB<classA_type> classB_type;

Why does the first version generate errors?

The compiler gets confused by the >> at the end of the template declaration. It thinks it is the right shift operator.You have to put a space between them in nested templates

//                         v
typedef classB<classA<char> > classB_type;

Hey, no big deal anyway, but...

In this thread you presented a problem. All I said was that the problem you presented in this thread, is exactly the same one *I* mentioned in your other thread (even the same type names), and about which I offered an explanation and a solution. That's all Smile | :)

I wasn't saying that this problem, was the same one you had before.

:-DSimple, I hit undo in the three different files involved, until it worked again. Then made the changes again with the final goal in mind.

Originaly the template compiled with out error, but it needed to be able to use a dirived class from a template that it depened on. Hince, I needed to make first template class and argument to the second template class. There was actualy a third template class that used the first two classes, so I don't know which one caused the complier to generate invalid code.

I hate not knowing, that's why I posted the original question. But when you're dealing with templates, inexact error messages can be very difficult to figure out.

DirectShow Audio-Video Synchronization

Alexander ^M.,3-Jul-05 6:19

3-Jul-05 6:19

Hi everyone.
I have a problem concerning the synchronization of the audio and video stream in my directshow filter graph.
I've coded an mpeg-ts demux, which timestamps the media samples, but the data stream has many data errors and so, when there is an error the video pauses for a short while and you can see all these nice mpeg blocks, but the audio continues without interruption.
That causes a slight delay between audio and video after some error have occured.
What can I do to prevent this?

Thanks for advice,
Alex
