如何在几秒钟后自动点击另一个按钮？ （Windows Phone 7） [英] How perform auto click on another button after few seconds ? (Windows phone 7)

问题描述

大家好，

如何在应用栏图标按钮的第二个按钮上执行自动点击几秒钟？

How do i perform an auto click on the second button in the app bar icon button after a few seconds?

private void btnStart_Click(object sender, EventArgs e)
{
   txtbx1.Text = "1" ;
   //sleep for 5 seconds then jump to btnChange
}
private void btnChange_Click(object sender, EventArgs e)
{
   txtbx2.Text = "2" ;
}

问题在于，如果我使用$ b，则两个文本框同时显示该值$ b 线程 。睡眠（5000）;

the problem lies that the two textbox appear the value at the same time if i use Thread.Sleep(5000);

提前致谢！

推荐答案

您可以使用类似的方法创建延迟而不冻结你的UI或你的应用程序：

You could use something like this to create a delay without freezing your UI or your apps :

private void btnStart_Click(object sender, EventArgs e)
{
	txtbx1.Text = "1" ;
	
	//use a BackgroundWorker to create a delay
	BackgroundWorker delayer = new BackgroundWorker();
	delayer.DoWork += new DoWorkEventHandler(_delayer_DoWork);
	delayer.RunWorkerCompleted += new RunWorkerCompletedEventHandler(_delayer_RunWorkerCompleted);
	if (!delayer.IsBusy)
		delayer.RunWorkerAsync();
}
private void btnChange_Click(object sender, EventArgs e)
{
   txtbx2.Text = "2" ;
}
	
void _delayer_DoWork(object sender, DoWorkEventArgs e)
{
	Thread.Sleep(3000);//pause the thread to create a delay
}

//Once delay is due, completed event is fire and you can work here
void _delayer_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
	((BackgroundWorker)sender).RunWorkerCompleted -= _delayer_RunWorkerCompleted;
	//Triger the btnChange Click event to simulate a mouse click
	btnChange_Click(btnChange, EventArgs.Empty);
}

如果需要，可以在BackgroundWorker上获得一些MSDN支持：

Here is some MSDN support on BackgroundWorker if needed : http://msdn.microsoft.com/en-us/library/cc221403%28v=vs.95%29.aspx

你应该对此很好;）
