Windows程序读取自身程序版本信息

自己写某产品时的代码，虽然网上有一堆一堆，但是这个是自己调试过的，自己留着给自己看

VOID GetInstanceVersion()
{
   BOOL version_get = FALSE;
   DWORD dwVersionInfoSize;  
   
   TCHAR szFile[255];
   memset(szFile,0x00,sizeof(szFile));
   GetModuleFileName(NULL,szFile,255);
   dwVersionInfoSize = ::GetFileVersionInfoSize(szFile, NULL);  
    if (0 == dwVersionInfoSize)  
    {  
        //return false;
        version_get = FALSE;
    }  

    char* pVersionInfo = new char[dwVersionInfoSize];  
    memset(pVersionInfo,0x00,sizeof(pVersionInfo));
    if (0 == GetFileVersionInfo(szFile, NULL, dwVersionInfoSize, pVersionInfo))  
    {  

        delete[] pVersionInfo;  
    }  

 
    VS_FIXEDFILEINFO* pVersion = NULL;  
    unsigned int nLen;  
    if(FALSE == ::VerQueryValue(pVersionInfo, _T("\"), (void**)&pVersion, &nLen))  
    {  
        delete[] pVersionInfo;  
        //return false;
        version_get = FALSE;
    }  

    int nFileVersionMS = pVersion->dwFileVersionMS;  
    int nFileVersionLS = pVersion->dwFileVersionLS;  
    
    valStr.Format(_T("%d.%d.%d.%d"),  (pVersion->dwFileVersionMS >> 16) & 0xFF, (pVersion->dwFileVersionMS) & 0xFF, (pVersion->dwFileVersionLS >> 16) & 0xFF, (pVersion->dwFileVersionLS));   

    delete[] pVersionInfo;  
}
