How to use Thread.Sleep in WPF application?
提问by GibboK
In a WPF application VS 2010, I basically need to print a document and check for errors after few seconds it start to print.
在 WPF 应用程序 VS 2010 中，我基本上需要打印文档并在几秒钟后开始打印时检查错误。
At the moment I am using Thread.Sleep(2000)but it does not work. The trycode I believe is running in the UI thread.
目前我正在使用，Thread.Sleep(2000)但它不起作用。该try相信代码在UI线程中运行。
Any idea how to fix it? Or better approach?
知道如何修复它吗？或者更好的方法？
In this specific case I do not care if the UI Thread is blocked for few seconds.
在这种特定情况下，我不在乎 UI 线程是否被阻塞了几秒钟。
try
{
printer = new Printer();
printer.PrintTicket(dataAdv);
// check eventual problem during printing like paper jamp
Thread.Sleep(2000);
if (monitorPrinter.IsPrinterReady() == false)
{
isPrinterReady = false;
MessageBox.Show("Problem during the printing!!!");
}
}

Solution to my problem thanks all for pointing me out in the right direction.
我的问题的解决方案感谢所有人为我指出正确的方向。
try
{
printer = new Printer();
printer.PrintTicket(dataAdv);
System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0, 0, 5);
dispatcherTimer.Start();
}
private void dispatcherTimer_Tick(object sender, EventArgs e)
{
if (monitorPrinter.IsPrinterReady() == false)
{
MessageBox.Show("SOME PROBLEM WHEN PRINTING!");
}
}
