Check if you did call AfxOleInit( ); before the custom control is created.

Also make sure the control has been properly registered.

how to write or create an xml file in mfc. pls help me. im new to this.

You can use MSXML or XmlLite if you want to stick with Microsoft. Also, expat and Xerces are nice alternatives. There ate plenty of articles and examples on The Code Project and on the web in general such as http://www.perfectxml.com/CPPMSXML/20020712.asp[^].

I guess you need to look up msxml.dll I think they're on to msxml4.dll but we still use msxml3.dll on CE. This Dll implements objects that let you read and write xml. It contains a parser and a generator so you get the XML as a memory based structure you can access and change and then write it back to disk as XML. Multi threading support is not great but it does the job  . Otherwise have a look for Sax, which I think is still the open XML parser standard. Enjoy.
Nothing is exactly what it seems but everything with seems can be unpicked.

Check out TinyXml, too.

Hello to all,
I am pretty new the C++ and don't yet fully understand the class structure. I tried to create a class in a header of my own. In my header I included the header files of other classes I wanna build my class members from.
But when, inside my class, I try to pick an object of type CIOBuffer:: ,for example, I can't get the choice list to open for my to choose the relevant member for me.
#include "JetByteTools\Win32Tools\IOBuffer.h"
#include "JetByteTools\Win32Tools\SocketServerEx.h"
class MesMng{
public:
CIOBuffer::
private:
}

That is an IDE issue and not a programming issue; it happens sometimes. Try typing the same thing after the headers (outside the class) to see if the list shows up. If that does not work then you will have to do it the old fashion way and look it up.

Dear

I think you might have mentioned "can not Access the not static member of Class with scope resolution operator". Am I right?

GOOD LUCK

will you post your code
, one who can see what is exact problem
|

The codes is such simple,
If I delete all the code from OnContextMenu(),but using a AfxMessageBox() instead.The messagebox remain couldn't be reach!

Dear
if you post your code , one can solve the problem.

I think the best way to learn the protocal is writing the simplest console programme, If you have any advise or source code or article to show me,that's the best present to me.
Thank you very much!

try "URLDownloadToFile" which is part of the shell API.
You have to include "Urlmon.h" and "Urlmon.lib" !
See MSDN for further details...

Hello everyone!
I gave up trying to convert my CPP files to CPP/H files...
The problem is this. I regularly use GCC for C++ coding, but I'm on Vista and that compiler doesn't work correctly on it. So I'll use Visual Studio instead.
But Visual Studio seems to compile each CPP file into its own object file and then link them all together, so I get a lot of undefined references... Is there any way to just compile index.cpp (my main file, where all other CPP files are called from)?
Thanks!

It's not really an answer to your question, as I don't know how to do it, but you might give a try in the compiler / linker options. Might be able to customize the build rules for your project.
Anyways, shouldn't you have used .h files in the first place  ? They do serve a purpose :P

That is normal (for every compiler I’ve used), as each file represents a separate unit. Undefined references are a different problem all together.
If you want a single object file, then use the #include syntax to include all the ‘.cpp’ files in a file called “index.cpp” and then only include that file in the project. Of course this is not normal and you may not have enough memory to do it, but it should work.

OK, since everyone seems to be against not using header files, I gave it another try.
This time it worked. Thanks everyone!

Old UNIX guy trying to learn some new tricks!
I am attempting to port some UNIX code to Visual C++.
I have found some code snippets, but need some high-level info. such as, in Windows speak, what am I looking for?
Can anyone point me to:
- Methods to do Async I/O on IP sockets? I use poll() or select() in UNIX.
- Does Windows have an equivalent of hostid()?
- What is the Windows equiv. of signals?
Any suggestions on good books would be appreciated, especially those geared to porting UNIX to Visual C++.
Thanks,
Dan
