从RC文件访问字符串？

Question

我有此.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，我要获取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\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
END

Answer 1

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);
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 ...
}
