_Hex function (VO28Run)

[stefan.ungemach]

Hi all,

it seems that the VO28Run function _Hex isn't implemented yet. Does anyone have a suggestion how to write this part of my code (I've posted the whole entity for better understanding of what I want do do) VO code properly in X#:

LOCAL ptrLanguage AS WORD PTR
LOCAL DIM aName[256] AS BYTE
LOCAL DIM aHex[8] AS BYTE
LOCAL ptrValue AS PTR

dwSize := GetFileVersionInfoSize( pszFile, @dwZero )

IF dwSize > 0

ptrInfo := MemAlloc( dwSize )

IF MemCheckPtr( ptrInfo, dwSize )

dwLangSize := 4 * _SIZEOF(WORD)
ptrLanguage := MemAlloc( dwLangSize )

IF MemCheckPtr( ptrLanguage, dwLangSize )

IF GetFileVersionInfo( pszFile, 0, dwSize, ptrInfo )

IF !VerQueryValue( ptrInfo, String2Psz( ;
"VarFileInfoTranslation" ),;
@ptrLanguage, @dwLangSize )
dwLangSize := 0
ENDIF

MemCopy( @aName[1], PTR( _CAST, "StringFileInfo" ), 18 )

IF dwLangSize >= 2
_Hex( ptrLanguage[1], @aHex[1] )
MemCopy( @aName[19], @aHex[5], 4 )
_Hex( ptrLanguage[2], @aHex[1] )
MemCopy( @aName[23], @aHex[5], 4 )

ELSE
// As default: Lang = US English, CharSet= Windows Multilingual
MemCopy( @aName[19], PTR( _CAST, "040904E4" ), 8 )

ENDIF

MemCopy( @aName[27], PTR( _CAST, "" ), 2 )
MemCopy( @aName[29], PTR( _CAST, pszValueName ), PszLen( pszValueName ))

ptrValue := MemAlloc( dwValueLength )

IF MemCheckPtr( ptrValue, dwValueLength )
IF VerQueryValue( ptrInfo, PSZ( _CAST, @aName[1] ), @ptrValue, @dwValueLength )
MemCopy( ptrValueBuffer, ptrValue, dwValueLength )
lSucceed := TRUE

ENDIF
MemFree( ptrValue )
ENDIF

ENDIF

MemFree( ptrLanguage )

ENDIF

MemFree( ptrInfo )

ENDIF
ENDIF

RETURN lSucceed

AFAIK the function _Hex sets the address that was passed a second argument to the HEX value of the first argument.
In your code however you are setting 4 elements of aHex, but you are not using them at all.
So what happens if you simply comment out that code?

Robert,

thanks for explaining. You're right, commenting out should do no harm.
