推荐答案

您无法在进程运行时提升进程的权限.解决此问题的常用方法是在需要时生成具有提升权限的新进程.该进程然后执行需要更高权限的工作，然后退出，将控制权释放回主进程.通过将新进程父窗口设置为主进程窗口的父窗口，您应该能够使其相当无缝.

You cannot elevate the permissions of a process while the process is running. the common way around this is to spawn a new process with elevated permissions when required. This process then does the work that requires higher privileges and then quits, releasing control back to the main process. You should be able to make it fairly seamless by setting the new processes parent window to that of the main process window.

另一种选择是使用所需的权限重新启动主程序.

The other alternative is relaunch the main program with the required permissions.

有一个 关于在 Vista 中使用 UAC 的文章，带有 C++ 示例，看起来很深入.

There is an article on UAC in Vista with C++ examples that looks quite in depth.
