Pls Find answer to your code....
I dont know how i can attach a file to code project message. there fore please copy from the message...

hi all,
i am having a class and i want to impliment 2 overloaded constructors as:
in .h file:
Document(const char* filename=NULL);
Document(const wchar_t* filename=NULL);
in .cpp file
Document::Document( const char* filespec )
{
m_pdoc = NULL;
load( filespec );
}
Document::Document( const wchar_t* filespec )
{
m_pdoc = NULL;
load( filespec );
}
the load function is also overloaded.
but it gives me warning saying:
warning C4520: 'Document' : multiple default constructors specified
and error saying:
error C2668: 'Document::Document' : ambiguous call to overloaded function
where i am going wrong?

Guess what happen if you don't pass anything to your constructor ? How will your compiler be able to select one of the two constructor ?
Remove the default parameter so that the compiler isn't confused in the case where you don't pass any argument.
|
|
|
|
|
in .h file:
Document(const char* filename=NULL);
Document(const wchar_t* filename=NULL);
The reason is here. You specified two default ctors because both of them are supposed to be called when no arhuments are passed to a ctor. So remove the default parameter value (=NULL) from one of ctors [or both of them].

Why not replace them with:
Document( const TCHAR *filename = NULL );

I have to transfer file via UDP. Please send me any sample codes or links or suggestions regarding this.

I think its not good idea to send a file with UDP.

You *can't* use UDP. UDP does not guarantee every packet will be delivered, which means the file received on the other end will most likely be corrupted.

Yes you can. You would need to implement some sort of "packet received" reply. If the sender didn't get it in time it would resend the packet. Such protocols exist.

That's a lot more work than it's worth. In fact, if such code exists, it would be a lot better to buy a library than to reinvent that particular wheel. Essentially, you're trying to turn UDP into TCP/IP. There's a reason both protocols exist.

You can do it, but by the time you implement all the checking for dropped datagrams and out-of-
sequence datagrams, you'll have rolled your own TCP 
Some tips: UDP datagrams can arrive out of order or not arrive at all. That means every
datagram will need a header containing some kind of info indicating it's position or index or
whatever so you can reassemble the data on the receiving end. You need to be able to resend
datagrams that don't arrive at all and allow for packets arriving out of order. This is the
stuff TCP does for you.
Good luck!

'nuf said already. I would suggest too, "Don't use UDP"!
Anything I will say you will bring it down to whatever you want.

I would be interested to hear why?
As many (Mark, etc) told there is some overhead in re-inventing TCP datastream capability with UDP, not mentioning that you can't use HTTP proxies to get out of a firewalled networks. Since you haven't stated your requirements I wonder why you want to do this.
