c++ - 从 RC 文件访问字符串？

我有这个.rc文件，其中包含用于 exe 文件详细信息的版本、描述等。

如何获取在代码中使用的值？例如，我想获取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

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\0"
            VALUE "FileDescription", "Software A\0"
            VALUE "FileVersion", "1.0.0.0\0"
            VALUE "InternalName", "SoftwareX\0"
            VALUE "LegalCopyright", "Copyright (C) Software Inc. All Rights Reserved\0"
            VALUE "OriginalFilename", "SoftwareA.exe\0"
            VALUE "ProductName", "Software A\0"
            VALUE "ProductVersion", "1.1.0.0\0"
        END
    END

使用GetFileVersionInfo()andVerQueryValue()函数，例如：

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

DWORD Handle;
DWORD Size = GetFileVersionInfoSize(FileName, &Handle);
if (Size == 0)
{
    // error handling ...
}

std::vector<BYTE> VersionData(Size);
if (!GetFileVersionInfo(FileName, Handle, Size, VersionData.data()))
{
    // error handling ...
}

LPTSTR Value;
UINT ValueLen;

if (VerQueryValue(VersionData.data(), TEXT("\\StringFileInfo\\040404b0\\ProductName"), (LPVOID*) &Value, &ValueLen))
{
    // use Value up to ValueLen chars as needed...
}
else
{
    // error handling ...
}

if (VerQueryValue(VersionData.data(), TEXT("\\StringFileInfo\\040404b0\\LegalCopyright"), (LPVOID*) &Value, &ValueLen))
{
    // use Value up to ValueLen chars as needed...
}
else
{
    // error handling ...
}
