At the first time, form gets displayed properly. On a particular event I am trying to reload the same form, while that time I am getting this exception. Anybody knows how to get rid of this.

推荐答案

我想到了一个问题，就是这样的最近。

I struck an issue just like this recently.

有每10,000次把手工艺的限制 - 很容易到达，如果你动态创建一个复杂的UI

There's a limit per process of just 10,000 handles - easy to reach if you're dynamically creating a complex UI.

要检查，如果发生这种情况，则使用任务管理器 - 到进程选项卡，打开列用户对象和GDI对象。然后，重现该问题。

To check if this is happening for you, use Task Manager - go to the Processes tab, turn on the columns for "USER Objects" and "GDI Objects". Then, reproduce the problem.

在我的情况下，用户对象计数准确地击中10,000，然后轰。

In my case, the USER Object count was hitting exactly 10,000 and then "boom".

如果这是发生了什么事对你来说，你需要确保你创建一个新的表格前，老控件妥善处理。您可能需要重新设计使用较少的手柄 - 这就是我需要做的。

If this is what's happening for you, you'll need to make sure that old controls are properly disposed before you create a new form. You might need to redesign to use less handles - this is what I needed to do.
