用WinInet做的FTP操作，为什么在Windows Mobile下会有问题（急救）
请路过的同行不吝赐教，万分感谢下面代码使用的是VB.Net
这个程序在WindowsXP下试了下是可以跑的，相应的get/put的操作也都能成功，
但是在手机模拟器下（VS2005自带的模拟器，选择Windows mobile6）在执行到InternetConnect的时候
返回的句柄是0。我试验的环境下手机模拟器的IE是可以上网的。

顺便问下怎么取得Windows mobile系统下的手机的文件路径 --------------------编程问答-------------------- 你用手机能上网的话,应该是DMA模式.
在你的模拟器设备上,将连接改成TCP连接传输看看.
具体:工具->选项->设备工具->设备->属性. --------------------编程问答-------------------- 试试 InternetOpenUrl --------------------编程问答--------------------
1.我用的确实是DMP模式（详见截图）
2.“将连接改成TCP连接传输”这个是在哪里设置的，我在模拟器配置里（如下图）找不到相应的
工具->选项->设备工具->设备->属性.
1楼的大侠能不能给各截图给我
--------------------编程问答--------------------
InternetOpenUrl的格式应该是
InternetOpenUrl（InternetOpen返回的句柄，ftp地址，http的包头，包头长度，flag，context）
这样的话ftp的“ID”和“密码”在哪里输入？
msdn里貌似是有写InternetOpenUrl能操作ftp的“Opens a resource specified by a complete FTP or HTTP URL.”（出自http://msdn.microsoft.com/en-us/library/aa385098(v=VS.85).aspx）
wang_junjie兄能不能给个具体的用InternetOpenUrl操作ftp的流程
--------------------编程问答--------------------
我说的是VS2005下..... 不是模拟器. --------------------编程问答-------------------- 试了“工具->选项->设备工具->设备->属性.”然后改成TCP的方法。用来这个以后再用activesync4.5来同步还是不行，如果不用activesync4.5这个工具的话遇到了"ConmanClient2.exe"找不到的问题，后来根据网上的信息搞了半天也没什么结果。bsr2009兄有什么不用activesync4.5这个工具上网的方法吗，或者给点mobile开发方面完整点的书或资料。
