推荐答案

为了使代码有效，它需要三件事：



1）IIS服务器需要安装相应版本的Word。

2）你需要一个非常宽容，友好的网络管理员。

3）你需要让你的用户坐在IIS服务器PC前面，而不是他自己的。



后者可能很难 - 我建议你试验远程传送。



当你在你的开发机器上测试它时，它工作是因为你安装了Word，而服务器和客户端都在同一台PC上。所以看起来它工作正常，但实际上Word实例是在服务器上打开的，而不是客户端。在生产中，两台PC不同，但Word实例仍将在服务器上打开，而不是客户端 - 因此他将无法随时看到它。



您无法从服务器上运行客户端PC上的任何应用程序（除非在非常特殊的条件下，几乎肯定不会在现实世界中应用）。安全性不会允许它，即使有办法判断客户端实际上是PC，而不是Mac，Android平板电脑，或支持网络的冰箱，或......

In order for that code to work, it needs three things:

1) The IIS Server needs to have the appropriate version of Word installed.
2) You need to have a very tolerant, and friendly web administrator.
3) You need to get your user to sit in front of the IIS server PC, instead of his own.

The latter may prove difficult - I suggest you experiment with teleportation.

When you tested it on your development machine, it worked because you had Word installed, and the server and client were both on the same PC. So it looked like it worked fine, but in practice the Word instance was opened on the Server, not the Client. In production teh two PCs are different, but the Word instance will still open on the Server, not the client - so he won't be able to see it at any time.

You cannot run any application on the Client PC from the Server (except under very special conditions which almost certainly will not apply in the real world). Security will not allow it, even if there was a way to tell if the client was actually a PC, rather than a Mac, or an Android tablet, or a web-enabled fridge, or...
