如何检测网页弹出的窗口并下"确定"?

[随风v5]

打开网页后弹出的窗口如何检测出来,并模拟鼠标点下"确定"?找了很多资料都没有头绪,再次麻烦大家一下了,谢谢!

这个窗口如图:

既然是弹出窗口,应该就需要用户交互,好像不能自动点确定吧.

AUTOIT我就知道可以,自动点没问题,但是想用C#做,找不到资料.

可以利用win32 API函数实现,不过有一点一定要注意:如果MessageBox的Caption为string.Empty,则比较麻烦,代码如下.
1.假设一个窗体中有如下代码:



public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
DialogResult result = MessageBox.Show(this, "test", string.Empty, MessageBoxButtons.YesNo, MessageBoxIcon.Information);
if (result == DialogResult.Yes)
{
this.DialogResult = DialogResult.Yes;
this.Hide();
}
else
{
this.DialogResult = DialogResult.No;
this.Hide();
}
}
}


2.如果我想测试这段代码,因为有消息框,必须点击按钮才可以让剩下的代码(红色标识)继续运行,否则代码覆盖率太低,怎么办?
3.解决方案:在vs 2008下测试通过

//利用反射机制调用私有方法,也就是按钮的Click方法

//得到窗体的句柄

catch (Exception ex)

timer.Stop();

timer.Stop();
Assert.AreEqual(DialogResult.Yes, form1.DialogResult);

}

void timer_Elapsed(object sender, ElapsedEventArgs e)

try
{
//取得消息框的句柄
IntPtr handler = GetWindow(frmHandler, (uint)GetWindowCmd.GW_ENABLEDPOPUP);//handler是MessageBox自己的句柄
if (handler != IntPtr.Zero)//不为零说明取得句柄成功
{
//取得消息框中的"是"按钮的句柄
handler = FindWindowEx(handler, 0, "Button", "是(&Y)");//按钮也作为了窗体处理,开始还真没想到可以这么用
//模拟点击按钮
SendMessage(handler, BM_CLICK, 0, 0);

找到了，呵呵

该程序怎么用啊？在哪里用？vba吗？
