查找IE窗口里的submit按钮，模拟点击
the following code will click submit button of html page in IE, modify it to click other button.

获取网页中的密码和文本输入框的内容
介绍
网页中的密码输入框和一般不同，他没有句柄之类的，但是可以通过IE的IHTMLInputTextElement接口获取！
本文是教你如何得到网页中输入框的内容。如何你想获取网页中的密码，则只要把if (lstrcmpi(strtype, _T("TEXT")) == 0) 改成if
(lstrcmpi(strtype, _T("PASSWORD")) == 0) 就可以了，如果你要是再加个实时监视的话，就成了密码窃取程序了咯！
主要思路：获取IE的IHTMLInputTextElement接口，这样就可以获取网页中的输入框（包括文本和密码输入框）的内容了。
