如何从Visual C++中的版本资源中读取

Question

我在C++项目的资源中有一个版本资源,其中包含版本号,版权和构建详细信息.是否有一种简单的方法可以在运行时访问它以填充我的帮助/关于对话框,因为我目前正在维护此信息的单独const值.理想情况下,该解决方案应适用于Windows/CE移动版和早期版本的Visual C++(6.0以上版本).

Answer 1

这是我原来答案的编辑版本.

bool GetProductAndVersion(CStringA & strProductName, CStringA & strProductVersion)
{
    // get the filename of the executable containing the version resource
    TCHAR szFilename[MAX_PATH + 1] = {0};
    if (GetModuleFileName(NULL, szFilename, MAX_PATH) == 0)
    {
        TRACE("GetModuleFileName failed with error %d\n", GetLastError());
        return false;
    }

    // allocate a block of memory for the version info
    DWORD dummy;
    DWORD dwSize = GetFileVersionInfoSize(szFilename, &dummy);
    if (dwSize == 0)
    {
        TRACE("GetFileVersionInfoSize failed with error %d\n", GetLastError());
        return false;
    }
    std::vector<BYTE> data(dwSize);

    // load the version info
    if (!GetFileVersionInfo(szFilename, NULL, dwSize, &data[0]))
    {
        TRACE("GetFileVersionInfo failed with error %d\n", GetLastError());
        return false;
    }

    // get the name and version strings
    LPVOID pvProductName = NULL;
    unsigned int iProductNameLen = 0;
    LPVOID pvProductVersion = NULL;
    unsigned int iProductVersionLen = 0;

    // replace "040904e4" with the language ID of your resources
    if (!VerQueryValue(&data[0], _T("\\StringFileInfo\\040904e4\\ProductName"), &pvProductName, &iProductNameLen) ||
        !VerQueryValue(&data[0], _T("\\StringFileInfo\\040904e4\\ProductVersion"), &pvProductVersion, &iProductVersionLen))
    {
        TRACE("Can't obtain ProductName and ProductVersion from resources\n");
        return false;
    }

    strProductName.SetString((LPCSTR)pvProductName, iProductNameLen);
    strProductVersion.SetString((LPCSTR)pvProductVersion, iProductVersionLen);

    return true;
}

Answer 2

为了获得与马克答案变化无关的语言结果:

   // replace "040904e4" with the language ID of your resources
    !VerQueryValue(&data[0], _T("\\StringFileInfo\\040904e4\\ProductVersion"), &pvProductVersion, &iProductVersionLen))
{
    TRACE("Can't obtain ProductName and ProductVersion from resources\n");
    return false;
}

至

UINT                uiVerLen = 0;
VS_FIXEDFILEINFO*   pFixedInfo = 0;     // pointer to fixed file info structure
// get the fixed file info (language-independent) 
if(VerQueryValue(&data[0], TEXT("\\"), (void**)&pFixedInfo, (UINT *)&uiVerLen) == 0)
{
    return false;
}

 strProductVersion.Format("%u.%u.%u.%u", 
    HIWORD (pFixedInfo->dwProductVersionMS),
    LOWORD (pFixedInfo->dwProductVersionMS),
    HIWORD (pFixedInfo->dwProductVersionLS),
    LOWORD (pFixedInfo->dwProductVersionLS));

Answer 3

也许会让你开始的事情:

TCHAR moduleName[MAX_PATH+1];
(void)GetModuleFileName(AfxGetInstanceHandle(), moduleName, MAX_PATH);
DWORD dummyZero;
DWORD versionSize = GetFileVersionInfoSize(moduleName, &dummyZero);
if(versionSize == 0)
{
    return NULL;
}
void* pVersion = malloc(versionSize);
if(pVersion == NULL)
{
    return NULL;
}
if(!GetFileVersionInfo(moduleName, NULL, versionSize, pVersion))
{
    free(pVersion);
    return NULL;
}

UINT length;
VS_FIXEDFILEINFO* pFixInfo;
VERIFY(VerQueryValue(pVersionInfo, const_cast<LPTSTR>("\\"), (LPVOID*)&pFixInfo, &length));

Answer 4

这样的事情将为您提供对资源数据的原始访问并让您入门:

HRSRC res = ::FindResource(NULL, MAKEINTRESOURCE(MY_VERSION_ID), RT_VERSION);
DWORD size = ::SizeofResource(NULL, res);
HGLOBAL mem = ::LoadResource(NULL, res);
LPVOID raw_data = ::LockResource(mem);
...
::FreeResource(mem);

Answer 5

谨防！使用FindResource..LockResource不正确。它有时会工作（就像在我的小型演示程序中一样），有时会导致访问冲突（例如：我正在为其制作演示的生产代码）。

VerQueryValue（）文档指出，应改为调用GetFileVersionInfoSize和GetFileVersionInfo。雷蒙德·陈（Raymond Chen）解释，请参见http://blogs.msdn.com/oldnewthing/archive/2006/12/26/1365215.aspx
