调试易

weebservices，remoting,xml，三种方法都能实现。

weebservices，socket,xml,remoting四种方法都能实现。

1、激活对方程序中的事件。
如何通过xml来激活对方程序的事件呢？

以上使用WM_COPYDATA实现进程间通迅

好容易 使用API的SendMessage

我看 看错了 有web程序 只好webservice了

我是楼主，补充说明：还是没有解决，那种最简单的方法使asp.net与普通程序之间通讯呢？都是在本地运行的。希望能给原代码，谢谢。
或者能不能用以下过程写个代码参考下？1、asp.net传一个数字给这个进程A；
2、进程A将收到的数字乘于999。
3、进程A将结果返回asp.net。
4、asp.net将结果显示在屏幕。

用Remoting是最简单的实现！如果是在本机通讯的话，建议你使用IPC通道。它比TCP通道性能高很多！

观注
但我觉得WEBserver的方法应最好，可是我不会，请高手给点说明!
