How to add data by Using Function CreateFile(...)

[mecheil.edwar]

I try to Create one text File By Using CreateFile(..) Function,

I want to add data ( x,y,x) coordinate to file By This way :

X Y Z
1 3 8
0 13 11

But when I write code I see Data Like this :
XYZ13801311,

I request any sample example to show me how to add and read data :

this is my code :

HANDLE hf; DWORD FileSize   ;
		hf =	CreateFile(TEXT("AAA.txt"),GENERIC_WRITE,NULL,NULL,OPEN_ALWAYS,NULL,NULL);
		FileSize = GetFileSize(hf,NULL);
		int a = sizeof(TEXT("x"));
WriteFile(hf,TEXT("x"),a,&FileSize,NULL);
WriteFile(hf,TEXT("y"),a,&FileSize,NULL);
WriteFile(hf,TEXT("z"),a,&FileSize,NULL);
WriteFile(hf,TEXT("1"),a,&FileSize,NULL);
WriteFile(hf,TEXT("3"),a,&FileSize,NULL);
...........
............
CloseHandle(hf);

Add '\n' as a line break.

Thanks Victor for your reply,

I wrote this code :
//~~~~~~~~~~~~~~~~~~~~~~~
WriteFile(hf,TEXT("3 \n"),a,&FileSize,NULL);
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~

But unlucky it is not working ( I Build Win32 Application and Use Win7 64Bit OS)
I try to learn How can I find a format to help me how to add spaces between Data and How to add New Lines,

once again I thank you for your answer and helping.

Thanks Victor for your reply,

I wrote this code :
//~~~~~~~~~~~~~~~~~~~~~~~
WriteFile(hf,TEXT("3 \n"),a,&FileSize,NULL);
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~

And what is the value of a in this case? Hopefully, NOT the

int a = sizeof(TEXT("x"));

And, please, read documentation for WriteFile API

	HANDLE hf;
	hf = CreateFile(TEXT("AAA.txt"),GENERIC_WRITE,NULL,NULL,OPEN_ALWAYS,NULL,NULL);
	DWORD writtenBytes = 0;
#ifdef UNICODE
	WORD bom = 0xFEFF;
	WriteFile(hf, &bom, sizeof(bom), &writtenBytes, NULL);
#endif
	LPCTSTR line = TEXT("X Y Z\r\n");
	WriteFile(hf, line, _tcslen(line) * sizeof(TCHAR), &writtenBytes, NULL);
	line = TEXT("1 ");
	WriteFile(hf, line, _tcslen(line) * sizeof(TCHAR), &writtenBytes, NULL);
	line = TEXT("3 ");
	WriteFile(hf, line, _tcslen(line) * sizeof(TCHAR), &writtenBytes, NULL);
	line = TEXT("8\r\n");
	WriteFile(hf, line, _tcslen(line) * sizeof(TCHAR), &writtenBytes, NULL);
	CloseHandle(hf);

	return 0;
}
