方法如下：
A页面的代码：
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim StrScript As String
StrScript = "<script>var win=null; win=window.open('WebForm2.aspx','MywinName'); win.document.all.item('open').click(); </Script>"
Me.RegisterStartupScript("popchick", StrScript)
End Sub
B页面代码：
html中：<input type="button" name="open" id="open" value="open" οnclick="alert('aaa');">Top

这是根据脚本的属性改写的，实例如下：
A页：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<META NAME="Generator" CONTENT="EditPlus">
<META NAME="Author" CONTENT="">
<META NAME="Keywords" CONTENT="">
<META NAME="Description" CONTENT="">
<script language="javascript">
var win=null;

function openWin()
{
win=window.open('Bpage.html','MywinName');
win.document.all.item("open").click();
}
</script>
</HEAD>
<BODY>
<input type="button" value="open" οnclick="openWin()">
</BODY>
</HTML>

B页：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<META NAME="Generator" CONTENT="EditPlus">
<META NAME="Author" CONTENT="">
<META NAME="Keywords" CONTENT="">
<META NAME="Description" CONTENT="">
</HEAD>

<BODY>
<input type="button" name="open" id="open" value="open" οnclick="alert('aaa');">
</BODY>
</HTML>

脚本的使用对于.net也是必不可少的。
希望大家多交流！Top

下面的程序演示的是启动一个计算器，然后，发送3，*,8，最后在计算器上显示24。

步骤如下：
1.启动计算器，得到handle
2.获得活动窗口的线程号,获得与自己程序的窗口相关的线程号
3.将两个线程的输入联系起来
4，SendKey
5.线程分离.
这是以前作的一个例子，有一些对你的这个问题没有用，自己挑挑吧。在我的计算机上已经运行通过，看到那个24了。

如果你那两个系统是单独的两个WinForm应用程序的话，就只有用消息了。
在A系统启动时，用XML文件记录其Handle的值；
在A系统中重载DefWndProc函数，用其来接收用户自定义的消息。如：
先写一个公用类（在A系统和B系统中都要引用）
class WM
{
const int user=0x400;
const int click=user+1;
}

在A系统中重载DefWndProc函数：

protected override void DefWndProc ( ref System.Windows.Forms.Message m )
{
switch(m.Msg)
{
case WM.click:
执行click事件
default:
base.DefWndProc(ref m);
break;
}
}

再在B系统中引入API函数PostMessage()函数，
通过前面A系统启动时保存在XML文件中的Handle来获取A系统的Handle，在B系统中用PostMessage()函数向这个Handle发消息即可。
如果你对消息的使用不够熟悉的话，可以给我邮件：

请教一个比较棘手的问题,上一次你帮我的哪个问题，我还想加一点，别的都能实现了，现在有一个控件很麻烦，text Field，怎样动态得到一个上传的值呀?其实，现在模拟选择这个过程。别的应该没有问题，现在主要一点，怎样模拟点击“浏览”，这个动作?别的调用API应该没有问题.

其实你的问题并不难，就是蠛诳退频拿毒俜ɡ雌平獗鹑说拿苈攵选?

实现方法就是枚举窗口，Windows提供了这样的API，应该是EnumWindows function.

You can see a lot of such software when searching google,

May you good luckTop

You have to guess
which is the UserName field,
which is the Password field,
which is the Confirm button.Top

<INPUT style="Z-INDEX: 101; LEFT: 83px; POSITION: absolute; TOP: 112px" type="file" runat="server" id="load">
用 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.RegisterStartupScript("pop", "<script>document.all.item('load').click();</script>")
End Sub
如果没有控件没有ID就要看实际情况了。Top
