先前写了系列 [小工具开发笔记—IE自动填表器—第零篇：序][IE]后，发现很多网友问我同一个问题，就是如何使用C\#（或者C++）操作IE浏览器（或者WinForm内嵌浏览器）里面的ActiveX控件。下面就以支付宝网站为例，写了一个完整的代码，分享一下，希望对有需要的网友有所帮助。

//  找到密码控件，填写123456  
 //     
 var alipwdPlaceholder  =  (document  as  IHTMLDocument3).getElementById( " \_fmu.l.\_0.p\_ie " )  as  IHTMLObjectElement;  
  
 //  以下代码使用支付宝控件原生方式进行填充，不过无效。。。  
 // dynamic alipwd = alipwdPlaceholder.@object;  
 // ALIEDITLib.IEditCtrl editCtl = alipwd;  
 // editCtl.Crypto(true, 0, "123456");  
  
 //  以下代码使用WM\_CHAR方式填充   
 IntPtr hwnd;  
IOleInPlaceActiveObject pao  =  alipwdPlaceholder.@object;  
 int  hr  =  pao.GetWindow( out  hwnd);  
 if  (hr  !=  0 )  
Marshal.ThrowExceptionForHR(hr);  
 //  找第一个子窗口   
 hwnd  =  (IntPtr)AutomationElement.FromHandle(hwnd).FindFirst(TreeScope.Children, Condition.TrueCondition).Current.NativeWindowHandle;  
 //  填充   
 foreach  ( char  c  in  " 123456 " )  
\{  
SendMessageW(( int )hwnd, WM\_CHAR, ( int )c,  0 );  
\}  
Console.WriteLine( " Input \[\{0\}\] into alipwd textbox(\{1\}). " ,  " 123456 " , hwnd);
