晚上好！

目前我正在开发一个WPF客户端一些休息服务。与其余的服务的各项通讯是没有问题的，并在一个额外的装配完成（各项通讯接口）。

currently i'm developing a wpf-client for some rest-service. the communcation with the rest-service is no problem and is done in an extra assembly (communcation-interface).

基本上是： 我有一个莫名其妙的搜索 - 按钮，它执行的方法。这种方法与服务进行通信，并更新了一些文本框和一个进度条（给用户一些图形信息，我们还有多远？）。 unfortunaly服务器，它承载的服务是有点跛，造成了一些严重的响应时间（约4秒）。这一点，另一方面，使我的WPF应用程序等，从而结束了在：去黑，titeling没有响应......

basically: i have a somehow "search"-button which executes a method. this method communicates with the service, updates some textboxes and a progress-bar (to give the user some graphic info, how far we are ...). unfortunaly the server, which hosts the service is a bit lame, causing some severe response-time (about 4 secs). this, on the other hand, causes my wpf-application to wait, which ends up in: going black, and titeling "not responding" ...

我已经试图把这种执行在另一个线程，但...这是合乎逻辑的，我不会得到任何访问我的WPF窗口的控制......

i've already tried to put this execution in another thread, but ... it's logical that i won't get any access to the controls of my wpf-window ...

ATM我真的很无奈...谁能给我一些HANDELING例程或解决方案？

atm i'm really helpless ... can anyone give me some handeling-routine or a solution?
