1.可以给一个已经做好的exe程序添加Web Services的功能(向别人提供接口和调用别人提供的接口)么？还是必须要新建一个Web Services的工程？2.如果是新建一个Web Services的工程，我选择Web App Debugger可以对他进行调试，也可以出现Form界面，但是我最终就可以这样发布？还是必须要发布成CGI或ISAPI的方式？ISAPI的方式是动态库，我没法添加Form界面啊，我还需要Form界面，CGI好像是控制台窗口的方式，我也没办法添加Form界面，在需要Form界面和Web Services的情况下，应该怎么做呢？谢谢各位！
2、delphi的Web Service服务端就是以ISAPI DLL形式发布的

1.如果是COM+工程的话，向外发布时，仅需要创建一个WEBSERVICE工程，把COM+进行包装一下即可！
2.如果没什么规划，我想，只能生写一个WEBSERVICE，直接读数据库了
(何况从WETSERVICE本身来说就是无状态的.)所以加FORM的想法还是取消为好.从EXE->CGI/ISAPI, 想方便的话就新建一个CGI/ISAPI程序,然后把EXE原有的功能UNIT添加过来就行了.
如果熟悉WS的开发,也可以直接改原代码, (也就是把相应的HTTPRIO.pas等加进来,再registe一些东西---相对麻烦一点).
