In the programming, excution file (.exe or .bin) is consist of below structure.

1. Text (code) segment

2. Data segment
2.1 Initialized Data
 2.1.1 Initialized read only Data
 2.1.2 Initialized read/write Data
2.2 Uninitialized (bss: Block Started by Symbol)
3. Heap segment (in the run time, size is decided)
Dynamic allocated variables
4. Stack segment (in the compile time, size is decided)
 Automatically allocated variables (local variables) and other stack frame entries

Binary or Excution file is "Text + Initialized Segment".

Usually, nowadays I read books which was written U.S. writers or Korean writers. But this book was written by Chinese person and the point of views are very different, in my case.

The world is wide and there are many things happen in the world.

In the pipe five by five

- One by one,

- Two by two,

- Five by five.

The famous saying is

1. "In the pipe five by five." you can hear this word in the game "Starcraft". but the original word in the movie "Aliens". "We're in the pipe, five by five."

2. In the bible, we can find "Noah brought all animals into the ark two by two"

Anything else?

Code Complete 1, in the floating point

Thin book is a great, wonderful, and fantastic.

How can he write this book, is he a genious?

In the floating point operation,

double dwNormal = 1.0;
double dwSum = 0;

int i = 0;
for (i=0; i<10; i++)
{
dwSum += 0.1;
TRACE("dwSum: %1.20f\n", dwSum);
}

if (dwSum == dwNormal)
{
TRACE("Numbers are the Same.");
}
else
{
TRACE("Numbers are Differnet.");
}

Can you guess the result?
dwSum == dwNormal is True or False?
In normal case, the result is False.
dwSum = 0.99999999999999989
In normal case, floating point precision, usually be represented to only 7 ot 15 digits of accuracy.

dwSum: 0.10000000000000001000
dwSum: 0.20000000000000001000
dwSum: 0.30000000000000004000
dwSum: 0.40000000000000002000
dwSum: 0.50000000000000000000
dwSum: 0.59999999999999998000
dwSum: 0.69999999999999996000
dwSum: 0.79999999999999993000
dwSum: 0.89999999999999991000
dwSum: 0.99999999999999989000

C code refactoring

refactoring & restructuring

refactoring is same input and output of function arguments

just change into the function's code

restructuring is same input and output of function argument or NOT.

In the project middle term, refactoring and/or restructuring

End of project, restructuring is NOT recommended, restructuring is recommended.

Video Clips

Nowadays in the Internet  we can download many video clips.

About 10 years ago, was it possible? In 1994 or 1995, at the university I downloaded many video clips from Broadcast companies or BBS. At that time I could not think, nowadays famous service, video clip streaming service. If I were known that service ...

So nowadays, through those service, I can watch many video clips such as Music video, TV show, Japan animation, and etc. Now it is related copyright, but it is possible ;-).

And more important information is,

I get more knowledge, I want to watch more video clips.

Nowadays, I like "Girl's generation".

display calculation result, long expression

In the C code, if the input value is very large and include fraction expression,

for example 3.141592 or 6350.29318. And want to display those values exactly.

How can you deal those values?

Now, I'm thinking, I use value shift and divide integer part and decimal part.

 3.141592 = 3 + 0.141592

 6350.29318 = 6350 + 0.29318

In the C language

 First, multiply big or large number

 6350.29318 * E14 = 635029318000000000

 and divide that value 6350 & 29318

 and check the decimal point, i.e., 5

 Second, use the sprintf(...) function

  such as "sprintf(SzTestResult, "%d.%0*d", lInteger, nDecimalPoint, lDecimal);"

And my question is, if there is or are  the C language exporter(s), how he or they deal(s) this issue?

::ShellExecute

Previous time, I used "WinExec(...)" function to execute windows application.

But other persion use the other windows API to execute windows application instead of "WinExec(...)". That function name is "ShellExecute(...)".

If you want to open web site (www.google.com) with internet explorer, you can write code as followed

 ::ShellExecute(

     NULL, 

     L"open", 

     L"http://www.google.com", 

     L"", 

     NULL, 

     SW_SHOWNORMAL);

But if you want open NEW web site in the NEW internet explorer, you can write code as followed

 ::ShellExecute(

     NULL, 

     L"open", 

     L"iexplore.exe", 

     L"http://www.apple.com", 

     NULL, 

     SW_SHOWNORMAL); 

How to build UNICODE in the Visual C++ 6.0

In the Visual C++ 6.0, if you want to compile UNICODE code,

You should chagne some configuration.

1. in the project, you delete _MBCS and input _UNICODE.

 [Project] -> [Settings] -> [C/C++ tab] -> [General Category]

  in the Preprocessor definitions, change _MBCS to _UNICODE

2. If you meet "Cannot open MFC42ud.dll(mfc42u.lib, mfcs42d.lib, or etc)"

 Copy the MFC library to your local machine. 

 From CD \VC98\MFC\LIB\all files to \Microsoft Visual Studio\VC98\MFC\Lib\ directory

3. [Project] -> [Settings] -> [Link] 

 In the Object/libary modules, insert mfc42u.lib

And compile the source code.

If you will see "msvctl.lib:error LNK2001 :unresolved external symbol _WinMain@16~~~"

 [Project] -> [Settings] -> [Link] 

 In the Entry-point symbol set "wWinMainCRTStartup"

That's all.

About Japanese animation

Nowadays I watched 2 animations ("anime" or "manga").

Time of Eve (イヴの時間)

 - http://timeofeve.com/e/

 - http://en.wikipedia.org/wiki/Eve_no_jikan

Voices of a Distant Star (ほしのこえ)

 - http://en.wikipedia.org/wiki/Voices_of_a_Distant_Star

Japanese animations have variety living thing, i.e. they treat many subject matters which I never think about before. In this reason I like "anime". And I want to learn Japanese.

Do you like Japanese animation?

Custom Token Macro in Source Insight

We suppose,

When you use the "Source Insight" as your source code editor,

Source code is as followed

 #define PACKED __packed

 typedef PACKED struct {

  int age;

  int tall;

 } MyStyleType;

Source Insight cannot parsing the variable "MyStyleType".

How can you fix it?

Source Insight support "*.tom" file.

In this case, we can change or add "c.tom"

c.tom file in the MyDocument\Source Insight\C.tom

We can add some key words,

_packed

packed

PACKED

That's all.

How to define "printf(...)" to "DEBUG(...)" in C/C++

When you make a program or programs, you need to check the program running condition.

In this reason, you want to use the debug message into the program.

In the debugging time you use the print put the logging messages and in the release time you don't want to use the logging messages.

When you use the macro "#define" how can you convert printf(char* format, ...) function to macro function?

As following,

// Multiple arguments

#define MSG_ERR(format, ...)    TRACE(ERROR, format, __VA_ARGS__)

#define MSG_WARN(format, ...)   TRACE(WARNING, format, __VA_ARGS__)

#define MSG_HIGH(format, ...)   TRACE(HIGH, format, __VA_ARGS__)

#define MSG_MID(format, ...)    TRACE(MIDDLE, format, __VA_ARGS__)

#define MSG_LOW(format, ...)    TRACE(LOW, format, __VA_ARGS__)

// Single argument

#define MSG_ERR(format)        TRACE(ERROR, format)

#define MSG_WARN(format)       TRACE(WARNING, format)

#define MSG_HIGH(format)       TRACE(HIGH, format)

#define MSG_MID(format)        TRACE(MIDDLE, format)

#define MSG_LOW(format)        TRACE(LOW, format)

Soap opera, TV Drama?

Nowadays I am watching TV series

Grey's Anatomy: Season 1, 2, 3, 4, and 5

 now, I am watching season 2.

Previous time, I watched

LOST: Season 1, 2, 3, 4, and 5

 I already watched season 1, 2, and 3.

HEROES: Season 1, 2, and 3

 I already watched season 1, 2.

and NOW, I'm watching Gray's Anatomy.

Previous time, I have watched 24, Numb3rs, ... 

When I was school student, I have watched many Americana's TV series,

for example MacGyver, Air Wolf, The Wonder Years and so on.

In the future, can I watch these TV series without caption?

Do you have a dream or a plan?

In the computer algorithm, there is "Divide and Conquer" i.e. when you solve the problem divide the problems and solve each of them. 

Today is the first working day of this year 2009.

Now, I am making this year's decision.

1. Increase family member.

2. Read English written books more than 10.

3. Join the on line lessons more than 10.

4. Upload blog more than 10 every month.

And end of this year, I will check them.

Let's start!

January 2nd, 2009.
