I am not sure if i understood your problem correctly.
Are you facing some problem with associating MSDN with VS2008?
If yes there should be some option to associate in settings of VS2008.
At least it is there is VS6.0 under Tools->Options->Help System. so you can try to find in VS2008.
I hope it helps.

Sandip.

did you see the image of my error screenshot? You know, when you press F1 in VS editor, the helper process(MSDN) will be started automately. Of course you can select to start it from the programs menu.
My problem is that, the helper can't show any useful documents although it has been started successfully.
Thanks

If it starts automatically then it is associated properly.. I just guessed that it might be problem when you install VS and MSDN separately.

I really don't know why. if so, im afraid i'll have to use msdn online, until i reinstall my os when some fatal errors occur on it.
Thanks all the same.

Hello,

I am trying to draw a video stream from a webcam or from another computer webcam on a Direct X surface. Can anyone give me some suggestion about any library or SDK I can use to do that. I know the part how to put a bitmap data on the Direct X surface, but need some suggestion about getting video data from the webcam and from the network.

Thanks!

Nacho

You can use windows media encoder to get the desire result . Also you must read directshow which having all the functionality of streaming and drawing on directx surface

Hi everyone,

I am facing some issues when i am porting my code from VC++6.0 to VC++9.0. Here is the list.

1. ByteVector::iterator it = (BYTE *)"ACI";

2. Error 3 error C2440: 'initializing' : cannot convert from 'BYTE *'
to 'std::_Vector_iterator<_Ty,_Alloc>'

hdr = *(ACI_HEADER *)it;
hdr is of type ACI_HEADER.
I tried de coupling the iterator and the ACI_Header but it dosent work.
hdr = (ACI_HEADER)(*it). This type of decoupling worked for unsigned char conversions but not
ACI_HEADER.

3. Error 17 error C2664: 'ComPtr<T>::ComPtr(const ComPtr<T> &)' : cannot
convert parameter 1 from 'int' to 'const ComPtr
ComPtr<CEventMsg> CEventMsg::FromBuffer(DataBuffer &buffer)

{
.....
.....
return NULL;
}

Any advices on these issues will be helpfull.

Thanks,
Pratap

Issues 1 and 2 - std::vector iterators used to be ordinary pointers. But they're not any more. I suspect this implies that your conversion from pointer to iterator (and vice versa) was (in terms of the C++ standard) erroneous, and you need to reformulate it in ways that are valid C++.

Issue 3 - try returning 'ComPtr<CEventMsg>(NULL)' or 'ComPtr<CEventMsg>()'?

Thanks for the suggestion. Issue 3 is solved but a similar type araised

ComPtr<CDMPPacket> CDMPSession::NewRecvPacket()

{

return new CDMPPacket; //Error

}

Error 1 error C2664: 'ComPtr<t>::ComPtr(const ComPtr<t>&)' : cannot convert parameter 1 from 'CDMPPacket *' to 'const ComPtr<t>&

should be replaced with return ComPtr<CDMPPacket>(new CDMPPacket);. It's the same pattern.

An iterator on an element in a collection is not the same as a pointer to that element. VC6 let you do that, and it happened to work, even though it was wrong to assume that the two were equivalent. Use &*it to convert an iterator to a pointer.

I'm trying to interpret the bCertificate member of the WIN_CERTIFICATE struct (for a debugging tool I'm writing). Does anyone have a code sample or link to a spec that shows how to interpret this data member?

Best wishes,
Hans

You can view the authenticode signature documents here:

http://www.microsoft.com/whdc/winlogo/drvsign/Authenticode_PE.mspx[^]

The bCertificate member is described on page 13 as:

"bCertificate is set to a variable-length binary array that contains the Authenticode PKCS #7 signedData"

I believe page 7 contains the signedData structure which is associated with the bCertificate member. It looks like you will have some additional research ahead of you as there is little documentation in this particular area.

Okay, I have a little war going on in my development, and I want y'all to weigh in with your thoughts. When I add a class to a project, let's call it the filter algorithm, we will know this as class CFilter. Now, do you name this file filter.h/cpp or cfilter.h/cpp?

Curious

By default for a class CFilter, the class wizard generates Filter.h/cpp. And for me it make more sense than cfilter.h/cpp. IMHO, Hungarian notations are best for source code, not for filenames. Smile | :)

My vote goes for Filter.h/cpp too.

so the topic is not related to C but to C++, right ?! ^^

my prefered choice : filter.* containing CFilter class definition/implementation...
