how can i make screen white in color and show animation icon

推荐答案

使用单独的线程来显示简单的请等待消息是特别有用的，特别是如果您没有太多的线程经验。



更简单的方法是创建一个请等待表单，并在缓慢加载表单之前将其显示为无模式窗口。主表单加载完成后，隐藏请等待表单。



通过这种方式，您只使用一个主UI线程首先显示请等待表单和然后加载你的主表单。



这种方法的唯一限制是你的请等待表单不能动画（如动画GIF），因为线程正忙着加载你的主要表格。

Using a separate thread to display a simple please wait message is overkill especially if you don''t have much experience with threading.

A much simpler approach is to create a "Please wait" form and display it as a mode-less window just before the slow loading form. Once the main form has finished loading, hide the please wait form.

In this way you are using just the one main UI thread to firstly display the please wait form and then load your main form.

The only limitation to this approach is that your please wait form cannot be animated (such as a animated GIF) because the thread is busy loading your main form.

PleaseWaitForm pleaseWait=new PleaseWaitForm ();

// Display form modelessly
pleaseWait.Show();

//  ALlow main UI thread to properly display please wait form.
Application.DoEvents();

// Show or load the main form.
mainForm.ShowDialog();

请试试这个
