DllCall( GetFileVersionInfo )

[ATR]

Hi all,

I try to use a function in a dll, but I have a parameter I don't understand..

$TailleFichier = DllCall("version.dll", "DWORD", "GetFileVersionInfoSize", "str", @ProgramFilesDir & "\CCleaner\CCleaner.exe", "DWORD", 0)
ConsoleWrite($TailleFichier[0] & @CRLF)
$Create = DllStructCreate("ptr")
$ptr = DllStructGetPtr($Create)
ConsoleWrite("$ptr : " & @error & @CRLF)
$result = DllCall("version.dll", "BOOL", "GetFileVersionInfoW", "wstr", @ProgramFilesDir & "\CCleaner\CCleaner.exe", "DWORD", "", "DWORD", $TailleFichier[0], "ptr", $ptr)

Thanks in advance

Have a look for a UDF called WinAPIEx.au3 and then you will be able to use the function _WinAPI_GetFileVersionInfo() or why not look at the native function FileGetVersion?

filegetversion don't work with all files. I analyze what these files using to identify the version information, and they use "GetFileVersionInfoSize" of version.dll file

What about the first option I suggested?

The function doesn't return error, but doesn't return the number version of my files !!

$tInfo = _WinAPI_GetFileVersionInfo($sFile)
 
 
$Return = DllStructGetPtr($tInfo)
ConsoleWrite("$InfoPTR : " & $Return & @CRLF) ; ==> return 0x02FCE010
 
 
 
Func _WinAPI_GetFileVersionInfo($sFile)
 
    Local $Ret, $tData
 
    $Ret = DllCall('version.dll', 'dword', 'GetFileVersionInfoSizeW', 'wstr', $sFile, 'ptr', 0)
    If (@error) Or (Not $Ret[0]) Then
        Return SetError(1, 0, 0)
    EndIf
    $tData = DllStructCreate('byte[' & $Ret[0] & ']')
    $Ret = DllCall('version.dll', 'int', 'GetFileVersionInfoW', 'wstr', $sFile, 'dword', 0, 'dword', $Ret[0], 'ptr', DllStructGetPtr($tData))
    If (@error) Or (Not $Ret[0]) Then
        Return SetError(1, 0, 0)
    EndIf
    Return $tData
EndFunc

ConsoleWrite("$InfoPTR : " & $Return & @CRLF) ; ==> return 0x02FCE010

And the number version is 3.10.0.1525

How can I convert 0x02FCE010 to 3.10.0.1525 ??

I tested with DllStructGetData($Return, $i) but don't work
