問題描述

我需要使用 C 或 C++ 中的 Win32 本機(jī) API 獲取 DLL 或 EXE 文件的產(chǎn)品版本和文件版本.我要不是尋找 Windows 版本，而是通過右鍵單擊 DLL 文件，選擇屬性"，然后查看詳細(xì)信息"選項(xiàng)卡所看到的版本號(hào).這通常是一個(gè)由四部分組成的虛線版本號(hào) x.x.x.x.

I need to get the product version and file version for a DLL or EXE file using Win32 native APIs in C or C++. I'm not looking for the Windows version, but the version numbers that you see by right-clicking on a DLL file, selecting "Properties", then looking at the "Details" tab. This is usually a four-part dotted version number x.x.x.x.

推薦答案

您將使用 GetFileVersionInfo API.

請(qǐng)參閱 MSDN 上的使用版本信息網(wǎng)站.

See Using Version Information on the MSDN site.

示例:

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
",
                    ( verInfo->dwFileVersionMS >> 16 ) & 0xffff,
                    ( verInfo->dwFileVersionMS >>  0 ) & 0xffff,
                    ( verInfo->dwFileVersionLS >> 16 ) & 0xffff,
                    ( verInfo->dwFileVersionLS >>  0 ) & 0xffff
                    );
                }
            }
        }
    }
    delete[] verData;
}
