WinCE6.0下如何实现WebService？？？

[icesoft2000]

在网上查找了一下，用gSOAP的很多。

但例子基本上是一样的，先要使用wsdl2h.exe和soapcpp2.exe生成指定网页的 WSDL。
可偶每次访问的网页地址可能不一样，如何解决？

以前没有接触过网络编程，大家有什么好的解决方式啊？

啊？你用CE做webService？ 做个客户端而已吧。 CE下用wininet加个XML解析库就可以了

C/C++ code


{
// TODO: Add your control notification handler code here
LPTSTR AcceptTypes[2] = {L"/MsgUDPServer/index.jsp HTTP/1.0\r\n"……

代码编译运行没错，可是得不到想要的结果啊

[多啦A孟]

你用MFC还是C#？C#直接添加web引用就可以用了

MFC 应该如何？

[多啦A孟]

MFC的，我也不会，好像就是你说的那个玩意，在C#里添加引用，IP地址也不能是动态的，需要在编译的时候就把IP地址设置好
