I wish to use MSXML2 in my application so I can look at some RSS feeds. I am using Visual C++ 6.0.
I have seen some example code but it mostly is C# but there is some code in one article on CP that has its code written in C++.
One line of code is like this:
::IXMLDOMNode *pNode = NULL;
When I add this code, I get a compile error. Must I download the latest SDK or something else?
Any help is much appreciated

You need to import the MSXML type library in your stdafx.h.
e.g.
#import <msxml14.dll> named_guids
That will at least get it to compile 
Try here[^] and here[^] as a good source of information on learning XML technologies.

Don't. Use expat, there is an article here on CodeProject that details exactly how to use it.

I'm writing a screen saver which will, from time to time, swap out and display different images. Currently it just repaints the new image - no problem. What I'd like to do is add some simple transition effects like fading from one image to another. I done some looking around to find out how to do this but have had no luck. I guess I can't get the right search keywords. Anyway, can someone point me in a direction of sample code or a free-but-good library (I prefer sample code)?
Thanks,
Randy

Hello All,
I am trying to run a basic genetic algorithm program.I am able to compile the program for a GA 1D Array but when i execute i am getting the following erros.

Debug/GA1DArra.exe : fatal error LNK1120: 1 unresolved externals.
I am a novice at programming and am basically stuck and am not able to proceed further. Please help me out if you could.
Thanks in advance.

Ramya, it seems you are trying to write a console application with windows-based programs' project settings.
ie,try Project -> Settings -> Link
and on the bottom box search for "/Subsystem:windows" and change it to
"/subsystem:console".
Im not sure tats the only one to be changed...
greatest thing is to do wot others think you cant

What kind of project have you selected?
or lookup for LNK2001 in the msdn. it would offer you some help and some additional knowledge to tackle this kind of problem.

Iam currently trying to write some file IO in visual c++ for a project iam on and I need to transport some number data (Integer & double) written in visual basic and then saved to a file. This data then needs to be read in by my visual c++ app. The problem iam having is that if I save the data as ascii text in VB then it is hard for VC to read the text in and put them into their correct types (ints & doubles).
I was considering using binary IO to write the data to file but iam unsure if a 16 bit integer or double would have the same representation in binary as it would in visual c++
Ideas anyone?

If you are planning on transporting the binary representation of these numbers across these development platform, not only will you need to ensure the correct binary format stored, but this still will not solve your problem of distinguishing between the integer and float (double) type.
I would suggest storing the numbers as a text value. You could then use a decimal digit to distinguish between wether your number should be treated as an integer or a float: eg:
If the following is stored in your text file:
"45,23,45.0,23.0"
Then you would infer that the first two numbers should be of type int, and the last two, of type double.

I have an application that runs on our server that I can no longer get support for.
The application runs great for days at a time and then it crashes.
I would like to write a task manager type utility that would automatically cancel the application.
Can you point me in the right direction? C++ or C# code highly desired.
thanks

what is the need for closing the appliation by using an external program?
you can do that when your application crashes..use the try(){ } catch(..) in every method, then you can catch the exceptions when application carshes. in the catch(), just do whatever you want to do..just terminate your threads or kill your application itself..or even invoke an instance of your application etc..
The returned pointer may be temporary and should not be stored for later use.

Thanks for your reply. As I indicated, I do not own the program and therefore do not have the source. The vendor no longer seems to be in business.
Anyway, I found a regerstry setting.
thanks

If the application has crashed, what would be left to cancel?

I have written a DLL which hooks different application on their thread
id.
Once the events are trapped in the dll , then the functions are
written separately to process the hooking in the dll.
But through out the dll , I have defined a static counter variable.
This is supposed to get modified in each of the trapping functions.
But it seems that the variable is not getting modified .
I need to pass the modified value to some other application using a
third function in the dll.
What should I do to ensure that the common variable is updatable from
all the Hook-processing functions
Thanks in anticipation

Place your static in a data segment like this.
#pragma data_seg (".StaticShare")
static unsigned int counter = 0;
#pragma data_seg ()
This assure that this variable will be available for all instance of your dll. You will have multi copy of your dll but only one data_seg (StaticShare).
P.S. you can name your data_seg the name you want.
Bye.

Hi, i wonder if anybody with knowledge of the TCP header can help me with this one:
I am casting some data from a buffer provided by the winpcap packet capture library into a struct I have defined to represent the TCP header, the header is at the start of the buffer and I am casting it like this:
<br />
tcpHeader = (tcp_header *) (UCHAR*) tempDatagram.pkt_data;
where the tcpHeader is of type:
<br />
typedef struct tcp_header{<br />
USHORT sport;
USHORT dport;
UINT32 seq;
UINT32 ack;
UINT x2:4;
UINT off:4;
UCHAR flags;
USHORT win;
USHORT crc;
USHORT urp;
} tcp_header;<br />
the cast is working upto the offset i think and then values are being filled in a little randomly from there so I dont think i have the tcp_header defined right for the TCP header, can anybody suggest how to fix it?

USHORT sport;
USHORT dport;
UINT32 seq;
UINT32 ack;
So far, so good. The next bit, according to "Internet Protocols Handbook," should be:
Data Offset - 4 bits
Reserved - 6 bits
Flags - 6 bits
I think I'd take the whole lot and make one 16-bit value of it, using ORs to set the flags and offset bitfields. Also, this reference indicates that a variable length Options field, padded by 0s in the low-order bits to 32-bits, is expected to precede the data block. The book doesn't mention whether the Options field is required; the RFC (793) may be more specific.
I've felt much better since I gave up hope.

Cheers for the reply roger,
Can you give me a hint at which data types would be best suited for these fields and how to declare them at that length in c++, considering that I would rather they were kept seperate from one another so no further processing is required to split the header data into component parts.
As you can tell I am a bit of a novice at c++ and the MFC's and i think i have bitten off a bit more than I can chew
