您将使用GetFileVersionInfo API。
请参阅MSDN站点上的使用版本信息。
样品:
DWORD verHandle = 0;
UINT size = 0;
LPBYTE lpBuffer = NULL;
DWORD verSize = GetFileVersionInfoSize( szVersionFile, &verHandle);
if (verSize != NULL)
{
LPSTR verData = new char[verSize];
if (GetFileVersionInfo( szVersionFile, verHandle, verSize, verData))
{
if (VerQueryValue(verData,"\\",(VOID FAR* FAR*)&lpBuffer,&size))
{
if (size)
{
VS_FIXEDFILEINFO *verInfo = (VS_FIXEDFILEINFO *)lpBuffer;
if (verInfo->dwSignature == 0xfeef04bd)
{
// Doesn't matter if you are on 32 bit or 64 bit,
// DWORD is always 32 bits, so first two revision numbers
// come from dwFileVersionMS, last two come from dwFileVersionLS
TRACE( "File Version: %d.%d.%d.%d\n",
( verInfo->dwFileVersionMS >> 16 ) & 0xffff,
( verInfo->dwFileVersionMS >> 0 ) & 0xffff,
( verInfo->dwFileVersionLS >> 16 ) & 0xffff,
( verInfo->dwFileVersionLS >> 0 ) & 0xffff
);
}
}
}
}
delete[] verData;
}

所有这些解决方案均无法正常运行(在我的系统上)。我发现版本号的四个部分中的每个部分都保存为16位值。
前两个数字保存在32位DWORD dwFileVersionMS中,后两个数字保存在dwFileVersionLS中。因此,我在输出部分编辑了您的代码,如下所示:
TRACE( "File Version: %d.%d.%d.%d\n",
( pFileInfo->dwFileVersionMS >> 16 ) & 0xffff,
( pFileInfo->dwFileVersionMS >> 0 ) & 0xffff,
( pFileInfo->dwFileVersionLS >> 16 ) & 0xffff,
( pFileInfo->dwFileVersionLS >> 0 ) & 0xffff
);
而且效果很好。输出的格式类似于我的系统:
主要,次要,修订版本

您可以使用版本信息API获得此信息。这是一个示例:
void PrintFileVersion( TCHAR *pszFilePath )
{
DWORD dwSize = 0;
BYTE *pbVersionInfo = NULL;
VS_FIXEDFILEINFO *pFileInfo = NULL;
UINT puLenFileInfo = 0;
// Get the version information for the file requested
dwSize = GetFileVersionInfoSize( pszFilePath, NULL );
if ( dwSize == 0 )
{
printf( "Error in GetFileVersionInfoSize: %d\n", GetLastError() );
return;
}
pbVersionInfo = new BYTE[ dwSize ];
if ( !GetFileVersionInfo( pszFilePath, 0, dwSize, pbVersionInfo ) )
{
printf( "Error in GetFileVersionInfo: %d\n", GetLastError() );
delete[] pbVersionInfo;
return;
}
if ( !VerQueryValue( pbVersionInfo, TEXT("\\"), (LPVOID*) &pFileInfo, &puLenFileInfo ) )
{
printf( "Error in VerQueryValue: %d\n", GetLastError() );
delete[] pbVersionInfo;
return;
}
// pFileInfo->dwFileVersionMS is usually zero. However, you should check
// this if your version numbers seem to be wrong
printf( "File Version: %d.%d.%d.%d\n",
( pFileInfo->dwFileVersionLS >> 24 ) & 0xff,
( pFileInfo->dwFileVersionLS >> 16 ) & 0xff,
( pFileInfo->dwFileVersionLS >> 8 ) & 0xff,
( pFileInfo->dwFileVersionLS >> 0 ) & 0xff
);
// pFileInfo->dwProductVersionMS is usually zero. However, you should check
// this if your version numbers seem to be wrong.
printf( "Product Version: %d.%d.%d.%d\n",
( pFileInfo->dwProductVersionLS >> 24 ) & 0xff,
( pFileInfo->dwProductVersionLS >> 16 ) & 0xff,
( pFileInfo->dwProductVersionLS >> 8 ) & 0xff,
( pFileInfo->dwProductVersionLS >> 0 ) & 0xff
);
}
