BOOL GetTextExtentPoint(

HDC hdc, // handle of device context
LPCTSTR lpString, // address of text string
int cbString, // number of characters in string
LPSIZE lpSize // address of structure for string size
);
===============================================================================
The EnumFontFamilies function enumerates the fonts in a specified font family that are available on a specified device. This function supersedes the EnumFonts function.
int EnumFontFamilies(
HDC hdc, // handle to device control
LPCTSTR lpszFamily, // pointer to family-name string
FONTENUMPROC lpEnumFontFamProc, // pointer to callback function
LPARAM lParam // address of application-supplied data
);

Parameters
hdc
Identifies the device context.
lpszFamily
Points to a null-terminated string that specifies the family name of the desired fonts. If lpszFamily is NULL, EnumFontFamilies randomly selects and enumerates one font of each available type family.
lpEnumFontFamProc
Specifies the procedure-instance address of the application-defined callback function. For information about the callback function, see the EnumFontFamProc function.
lParam
Points to application-supplied data. The data is passed to the callback function along with the font information.

Return Values
If the function succeeds, the return value is the last value returned by the callback function. Its meaning is implementation specific.
=============================================================================
The EnumFontFamiliesEx function enumerates all fonts in the system that match the font characteristics specified by the
LOGFONT structure. EnumFontFamiliesEx enumerates fonts based on typeface name, character set, or both. It is recommended that Win32-based applications use this function rather than EnumFontFamilies to enumerate fonts.

int EnumFontFamiliesEx(
HDC hdc, // handle to device context
LPLOGFONT lpLogfont, // pointer to logical font information
FONTENUMPROC lpEnumFontFamExProc, // pointer to callback function
LPARAM lParam, // application-supplied data
DWORD dwFlags // reserved; must be zero
);
=================================================================================
The EnumFonts function enumerates the fonts available on a specified device. For each font with the specified typeface name, the EnumFonts function retrieves information about that font and passes it to the application-defined callback function. This callback function can process the font information as desired. Enumeration continues until there are no more fonts or the callback function returns zero.
This function is provided for compatibility with earlier versions of Microsoft Windows. Win32-based applications should use the EnumFontFamilies function.

int EnumFonts(
HDC hdc, // handle to device context
LPCTSTR lpFaceName, // pointer to font typeface name string
FONTENUMPROC lpFontFunc, // pointer to callback function
LPARAM lParam // address of application-supplied data
);

Parameters
hdc
Identifies the device context.
lpFaceName
Points to a null-terminated character string that specifies the typeface name of the desired fonts. If lpFaceName is NULL, EnumFonts randomly selects and enumerates one font of each available typeface.
lpFontFunc
Points to the application-defined callback function. For more information about the callback function, see the EnumFontsProc function.
lParam
Points to any application-defined data. The data is passed to the callback function along with the font information.


Return Values
If the function succeeds, the return value is the last value returned by the callback function. Its meaning is defined by the application.
======================================================================
The GetSystemDefaultLangID function retrieves the system default language identifier.

LANGID GetSystemDefaultLangID(VOID)

Parameters
This function has no parameters.
Return Values
If the function succeeds, the return value is the system default language identifier.
================================================================================
The GetUserDefaultLangID function retrieves the user default language identifier.

LANGID GetUserDefaultLangID(VOID)

Parameters
This function has no parameters.
Return Values
If the function succeeds, the return value is the user default language identifier.
================================================================================

BOOL GetStringTypeA(

LCID Locale, // locale identifer
DWORD dwInfoType, // information-type options
LPCSTR lpSrcStr, // pointer to the source string
int cchSrc, // size, in bytes, of the source string
LPWORD lpCharType // pointer to the buffer for output
);
Parameters
Locale
LOCALE_SYSTEM_DEFAULT Default system locale
LOCALE_USER_DEFAULT Default user locale
dwInfoType
CT_CTYPE1 Retrieve character type information.
CT_CTYPE2 Retrieve bidirectional layout information.
CT_CTYPE3 Retrieve text processing information.
lpSrcStr
Points to the string for which character types are requested. If cchSrc is -1, the string is assumed to be null terminated. This must be an ANSI string. Note that this can be a double-byte character set (DBCS) string if the locale is appropriate for DBCS.
cchSrc
Specifies the size, in bytes, of the string pointed to by the lpSrcStr parameter. If this count includes a null terminator, the function returns character type information for the null terminator. If this value is -1, the string is assumed to be null terminated and the length is calculated automatically.
lpCharType
Points to an array of 16-bit values. The length of this array must be large enough to receive one 16-bit value for each character in the source string. When the function returns, this array contains one word corresponding to each character in the source string.

Return Values
If the function succeeds, the return value is nonzero.
=================================================================
BOOL GetStringTypeW(

DWORD dwInfoType, // information-type options
LPCWSTR lpSrcStr, // address of source string
int cchSrc, // number of characters in string
LPWORD lpCharType // address of buffer for output
);
==========================================================================
The GetSystemDefaultLangID function retrieves the system default language identifier.
LANGID GetSystemDefaultLangID(VOID)


Parameters
This function has no parameters.

Return Values
If the function succeeds, the return value is the system default language identifier.

Remarks
For more information about language identifiers, see Language Identifiers and Locales.
===============================================================================
int WideCharToMultiByte(

UINT CodePage, // code page
DWORD dwFlags, // performance and mapping flags
LPCWSTR lpWideCharStr, // address of wide-character string
int cchWideChar, // number of characters in string
LPSTR lpMultiByteStr, // address of buffer for new string
int cchMultiByte, // size of buffer
LPCSTR lpDefaultChar, // address of default for unmappable characters
LPBOOL lpUsedDefaultChar // address of flag set when default char. used
);


Parameters

CodePage
Specifies the code page used to perform the conversion. This parameter can be given the value of any codepage that is installed or available in the system. The following values may be used to specify one of the system default code pages:

Value Meaning
CP_ACP ANSI code page
CP_MACCP Macintosh code page
CP_OEMCP OEM code page

dwFlags
A set of bit flags that specify the handling of unmapped characters. The function performs more quickly when none of these flags is set. The following flag constants are defined:

Value Meaning
WC_COMPOSITECHECK Convert composite characters to precomposed characters.
WC_DISCARDNS Discard nonspacing characters during conversion.
WC_SEPCHARS Generate separate characters during conversion. This is the default conversion behavior.
WC_DEFAULTCHAR Replace exceptions with the default character during conversion.

When WC_COMPOSITECHECK is specified, the function converts composite characters to precomposed characters. A composite character consists of a base character and a nonspacing character, each having different character values. A precomposed character has a single character value for a base/nonspacing character combination. In the character ? the
e is the base character, and the accent grave mark is the nonspacing character.

When an application specifies WC_COMPOSITECHECK, it can use the last 3 flags in this list (WC_DISCARDNS, WC_SEPCHARS, and WC_DEFAULTCHAR) to customize the conversion to precomposed characters. These flags determine the functions behavior when there is no precomposed mapping for a base/nonspace character combination in a wide-character string. These last 3 flags can only be used if the WC_COMPOSITECHECK flag is set.
The functions default behavior is to generate separate characters (WC_SEPCHARS) for unmapped composite characters.

lpWideCharStr
Points to the wide-character string to be converted.

cchWideChar
Specifies the number of characters in the string pointed to by the lpWideCharStr parameter. If this value is -1, the string is assumed to be null-terminated and the length is calculated automatically.

lpMultiByteStr
Points to the buffer to receive the translated string.

cchMultiByte
Specifies the size in characters of the buffer pointed to by the lpMultiByteStr parameter. If this value is zero, the function returns the number of bytes required for the buffer. (In this case, the lpMultiByteStr buffer is not used.)

lpDefaultChar
Points to the character used if a wide character cannot be represented in the specified code page. If this parameter is NULL, a system default value is used. The function is faster when both lpDefaultChar and lpUsedDefaultChar are NULL.

lpUsedDefaultChar
Points to a flag that indicates whether a default character was used. The flag is set to TRUE if one or more wide characters in the source string cannot be represented in the specified code page. Otherwise, the flag is set to FALSE. This parameter may be NULL. The function is faster when both lpDefaultChar and lpUsedDefaultChar are NULL.



Return Values

If the function succeeds, and cchMultiByte is nonzero, the return value is the number of bytes written to the buffer pointed to by lpMultiByteStr.
If the function succeeds, and cchMultiByte is zero, the return value is the required size, in bytes, for a buffer that can receive the translated string.
If the function fails, the return value is zero. To get extended error information, call GetLastError. GetLastError may return one of the following error codes:

ERROR_INSUFFICIENT_BUFFER
ERROR_INVALID_FLAGS
ERROR_INVALID_PARAMETER
