Consume C# DataSet from .Net webservice

Hi
you wish to consume DataSet from .NET webservices , anyway i could not find an easy way to do it , as you do it within c# code, you must deal with XML parsers.
any way, a very good explanation and description could be found here Web Services and DataSets.

In short .. it is most recommended to expose the results as array of objects ,when you want your Java consumer be happy.
.... i used axis 2 to generate webservice proxies .

good luck

How to get Facebook friends status ? - online or not

just found this post , i didn't test it yet , and i cant promise anything about it.
you need the next Extended permission: friends_online_presence

To actively query the online presence of your friends use the next graph call:

https://api.facebook.com/method/fql.query?access_token='((INSERT ACCESSTOKEN HERE))'&query= SELECT online_presence FROM user WHERE uid = '((UID OF FRIEND))'

That should return the info.
i hope it will work, i will report when it will work for me.

enjoy

C++ code description in XML

The GCC-XML, the XML output extension to GCC! 

Development tools that work with programming languages benefit from their ability to understand the code with which they work at a level comparable to a compiler. C++ has become a popular and powerful language, but parsing it is a very challenging problem. This has discouraged the development of tools meant to work directly with the language.

There is one open-source C++ parser, the C++ front-end to GCC, which is currently able to deal with the language in its entirety. The purpose of the GCC-XML extension is to generate an XML description of a C++ program from GCC's internal representation. Since XML is easy to parse, other development tools will be able to work with C++ programs without the burden of a complicated C++ parser.

Predefined Macros in c++

In ANSI c++ , there are some predefined macro that you can used , for example to write to your logs.

 __DATE__ 
A character string literal containing the date when the source file was compiled. The date will be in the form:
   "Mmm dd yyyy"
 __FILE__ 
Defined as a character string literal containing the name of the source file.
 __LINE__ 
Defined to be an integer representing the current source line number.
 __STDC__ 
Defined if the C compiler conforms to the ANSI standard. This macro is undefined if the language level is set to anything other than ANSI.
 __TIME__ 
Defined as a character string literal containing the time when the source file was compiled. The time will be in the form:
   "hh:mm:ss"

__FUNCTION_
access the name of a currently executing function programmatically.



more macros could be found here Standard Predefined Macro, more about __FUNCTION__  could be found here Retrieve a Function's Name Programmatically




Code sample:

#include 

#ifdef __STDC__
# define CONFORM "conforms"
#else
# define CONFORM "does not conform"
#endif
int main(void)
{
printf("Line %d of file %s has been executed\n", __LINE__, __FILE__);
printf("This file was compiled at %s on %s\n", __TIME__, __DATE__);
printf("This program %s to ANSI standards\n", CONFORM);
}
