I guess you cannot change it progmatically. Maybe someone else would explain it better to you cause I'm not the most knowledgable person out there in the network thing. (getting into databases right now and probably later into networks)

I don't think it is possible when you are already connected... You must first disconnect then change the address or it may cause some problems because one machine address can't have 2 IP addresses at the same time. (I don't know how to change it even if you disconnect... but I think you must disconnect first!)
Well... I am a beginner ...

This is the closest I could find on the subject (using netsh to change the interface parameters):
MSKB #257748[^]
I've never used netsh personally, but it seems like the easiest way to go.

Thanks for the input, I'm sorry I didn't respond sooner. I have been feeling really lazy lately and haven't gotten around to working on it

Hi again!
I found a way but as I mentiones before you will have to reboot each time you change it. ( it is registry stuff)

I hope this will help!

Hi,
I'm using a CWinThread to send and recieve ICMP packets (pings).
but while recieving the echo replys the thread exits.
Thats the code I'm calling:
<br />
char* echoReply = new char[50];<br />
int nRet;<br />
int nAddrLen = sizeof(struct sockaddr_in);<br />
sockaddr_in lpsaFrom;<br />
lpsaFrom.sin_family = AF_INET;<br />
lpsaFrom.sin_port = 0;<br />
lpsaFrom.sin_addr.s_addr = inet_addr("192.168.6.100");<br />
<br />
nRet = recvfrom(s,<br />
echoReply,<br />
sizeof(echoReply),<br />
0,<br />
(sockaddr*) &lpsaFrom,<br />
&nAddrLen);<br />
when calling recvfrom() the thread breaks down. even the debugger does not stop at any breakpoints i have set after the recvfrom call.
has anybody an idea?
PS: recv also doesn't work and bind works fine...

This may not fix the problem but...
sizeof(echoReply) will return 4 (the size of the pointer), not 50. You need to specify 50 instead of sizeof(echoReply).

My question is though, is standard the same as student/intro editions? Becuase I used to have a version of VC++ 6.0 that came bundled with a teach yourself programming package but the program wouldnt let me make programs stand alone so that i could give it to a friend or something.. If they wanted to use it they'd have to compile my code every time and so did i..
Is the standard edition of VC++.net the same? Should I have gotten profesional?
I'm just learning C++ so am not sure what all the information about the programs are so it's hard for me to tell the benifits and abilities.
Any help is appriciated,
thanks.

No. The programs you build with the standard edition of Visual C++ .NET do not need to be compiled more than once unless you need to make changes to the program. In other words, the Standard Edition of Visual C++ .NET makes stand alone programs. Have fun! 
I am using the same program to develop a quite large application being written in C++ and it does the job for me. If you have any other questions, let me know.

greetings all.
I have a project consisting of about 20 source files.
In some the call to timeGetTime() works. In others it is an illegal identifier.
What include file do I need for this API call ?
Cheers

Header: Declared in Mmsystem.h; include Windows.h.
Library: Use Winmm.lib.
How about taking a look at the MSDN? (no offense )

Thanks...no offense taken...
I have a few problems with MSDN and the C++ help files: namely that they told me that I needed a header called windows.h
The source file in question has the following includes
windows.h
windowsx.h
ddraw.h
stdio.h
(Exactly the same headers as the source file that works).
NB: noticed that the source files that use timegetTime() are all class member functions: what is going on....MSDN does not cover this one (or I can't drive it).
Cheers

Well, if your project includes these four includes, then there's missing the mmsystem.h header file. And second, link with winmm.lib. I do it this way:
#pragma comment(lib, "winmm.lib")
But you can do it in the project options as well.

Cheers.
I found some code that had the include winmm.lib and used that: worked fine.
Can anyone shed light on why the object source files had no problem when they had the same include statements ?
Thanks for all responses: much appreciated.;)

Hello all .
i having some question about array size.
lets say i wanto declare this array...its an "unsigned long".
lets say i wanted it the array to have the size of "8"..
so i will declare like this :
unsigned long Data[8];
ok...lets say now.. i wanto to create a "unsigned long" array.. but i not yet sure whats the size...becoz its depends on the datas that will be key in by user...
ok.. lets say..
int arraysize;
arraysize=a+b;
(where a and b are both int keyed in by user...)
then.. how i wanto set the Data array into the size of "arraysize"??
can i do it like this :
unsigned long Data[arraysize];
i tired but..error... so i hope u guys can help me out..how to solve this problem...what should i do to set my array size according to wat the datas user keyed in?
thanks...

I don't think I should give you a direct answer on your question because, frankly, doing so would not be a help to you, in the long run. I suggest you complete the C++ text book(s) you are reading first, and I guarantee you'll find the solution by yourself. As a hint, please take a look at the new and delete operators(I assume you are learning C++) about how to use dynamic arrays and how to free the memory.
Really, I'm sorry for not being a one-time help but if you are developing an application, ask that question here, get a direct answer, then return to your application, I'm afraid your customer(or your teacher) will end up get mad.

I can't agree with you more!
I am seeking...
For what?
Why did you ask me for what? I don't know!

You need to create dynamic arrays on the heap using new and delete the memory yourself using delete [].
unsinged long *data = new unsigned long[arraysize];<br />
<br />
<br />
delete[] data;<br />
An alternative would be a std::vector.

hi
it seems that u really have not finished your C++ courses.
the array that you are using is not a dynamic array.
you need to know more about POINTERS. These are really the dynamic arrays.
if u r in a hurry u can use these lines. but my advice is that you should read more in C++ specially in pointers and dynamic memory allocation.
First you declare ur array like this:
unsigned long *Data;
when you know the actaual size of ur array you set it like this:
Data= new unsigned long[arraySize];
now u can use it as an ordinary array.
after u finish using it is better to free the memor u allocated
delete Data;
i hope this works with you but you still need to know more in C++
Good Luck.
