从rc文件访问字符串

有.rc文件，其中包含用于exe文件详细信息的版本，说明等。

如何获得在代码内使用的值？例如，要获取ProductName。

IDI_ICON1   ICON    DISCARDABLE "abc-logo.ico"

#if defined(UNDER_CE)
#include <winbase.h>
#else
#include <winver.h>
#endif

VS_VERSION_INFO VERSIONINFO
FILEVERSION 9, 9, 9, 9
PRODUCTVERSION 12, 01, 15, 1
FILEFLAGSMASK 0x3fL
FILEFLAGS 0
FILEOS VOS_NT_WINDOWS32
FILETYPE VFT_APP
FILESUBTYPE VFT2_UNKNOWN

BEGIN
    BLOCK "VarFileInfo"
    BEGIN
        VALUE "Translation", 0x0404, 1200
    END
    BLOCK "StringFileInfo"
    BEGIN
        BLOCK "040404b0"
        BEGIN
            VALUE "CompanyName", "Company A"
            VALUE "FileDescription", "Software A"
            VALUE "FileVersion", "1.0.0.0"
            VALUE "InternalName", "SoftwareX"
            VALUE "LegalCopyright", "Copyright (C) Software Inc. All Rights Reserved"
            VALUE "OriginalFilename", "SoftwareA.exe"
            VALUE "ProductName", "Software A"
            VALUE "ProductVersion", "1.1.0.0"
        END
    END
END

需要使用GetFileVersionInfo()和VerQueryValue()函数

例如：

TCHAR FileName[MAX_PATH];
GetModuleFileName(NULL, FileName, MAX_PATH);

DWORD Handle;
DWORD Size = GetFileVersionInfoSize(FileName, &Handle);

std::vector<BYTE> Data(Size);
GetFileVersionInfo(FileName, Handle, Size, Data.data());

LPTSTR ProductName;
UINT Len;
VerQueryValue(Data.data(), TEXT("\StringFileInfo\040404b0\ProductName"), (LPVOID*) &ProductName, &Len);

// use ProductName up to Len chars as needed...

LPTSTR LegalCopyright;
VerQueryValue(Data.data(), TEXT("\StringFileInfo\040404b0\LegalCopyright"), (LPVOID*) &LegalCopyright, &Len);

// use LegalCopyright up to Len chars as needed...
