windows mobile下的MFC程序，怎么用http上传文件？
在一个MFC程序中，需要向服务器上传文件。 参考了一个windows xp下的程序，可以正常运行的，但是代码移植到windows mobile下就不行，主要是wm不支持这几个函数：CInternetFile::Write
CHttpFile::SendRequestEx
CHttpFile::EndRequest
请问，该怎么办？ 有什么方法可以实现这个功能吗？ 谢谢
另外，发觉有很多pc机里能用的win api函数，在windows mobile下用不了，不知道微软是出于什么考虑，要禁用这些函数。

就是通过socket上传 --------------------编程问答-------------------- 拿PPC跟PC比，楼主牛。 --------------------编程问答-------------------- winInet， 开发文档上有例子。。很简单
