桌面设置程序v1.1

windows 获取桌面路径的API函数：SHGetSpecialFolderPath

 1.读取桌面路径的函数：

wstring GetDesktopPath()
{
    TCHAR szPath[_MAX_PATH];  
    SHGetSpecialFolderPath(NULL,szPath,CSIDL_DESKTOP,0); 
    return wstring(szPath);
}
2.修改桌面路径

bool SetDeskTopPath(LPCTSTR szNewPath) 
{
    bool bResult = true ; 
    LPCTSTR lpKeyName =  L"Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Shell Folders";
    DWORD dwSize = wcslen(szNewPath) * sizeof(TCHAR); 
    LSTATUS ret =0; 
    HKEY hKey  = 0 ; 
    try { 
        ret=(::RegOpenKeyExW(HKEY_CURRENT_USER,lpKeyName,0,KEY_READ,&hKey));
        if(ret!=ERROR_SUCCESS){ throw L"错误：无法打开有关的hKEY"; }
 
        LSTATUS ret = ::RegSetKeyValueW(HKEY_CURRENT_USER,lpKeyName,L"desktop",REG_SZ,szNewPath,dwSize);
        if(ret !=ERROR_SUCCESS) {throw L"写入注册表错误!";}
 
    }catch(LPCTSTR lpDescript)
    {
        std::cout<<L"错误消息"<<lpDescript<<endl;
        bResult = false ; 
    }
    ::RegCloseKey(hKey) ; 
    return bResult ; 
}
