Form.Shown后如何引发句柄错误？

我有，我们有一些可怕的复杂的代码抛出了一个Win32ExceptionForm.Shown后如何引发句柄错误？

错误创建窗口句柄的问题。

望着调用堆栈我看到了堆的底部是

MainForm_ShownEvent(object sender, EventArgs e)//I Had a type-o here...arguments were wrong 
{ 
    someControl.Parent = contentPanel;//call starts here 
}

堆栈的顶部来自一个自定义事件。事件处理程序在MainForm

anotherControl_RefreshEvent(object sender, PhysDocEventArgs e) 
{ 
    Text = titleBarText;//win32 exception 
}

这怎么可能？我们不保证一旦调用Form.Shown就会创建句柄吗？

更新

立即窗口告诉我this.Handle为0，其中this是MainForm的对象。

堆栈跟踪（这是19页长，不得不删除一些）

也许它是在有问题的窗体上的控件的句柄，而不是窗体本身的句柄。 –

@SteveWellens - titleBarText是一个字符串对象。文本是“MainForm.Text”的一个属性。我相信这是不可能的，因为这行代码没有涉及任何控制。 –

你可以检查句柄，这个值是多少？表单上有很多控件吗？你可以尝试暂时删除它们，看看问题是否消失。 –

这是有异常的容易诊断和一个非常普遍的原因。开始诊断任务管理器，进程选项卡。查看+选择列，勾选USER对象。当你在它的时候，勾选GDI Objects和Handles。运行程序并在使用程序功能时观察进程的USER对象值。

如果您看到的值稳步增加，那么您的程序正在泄漏窗口句柄。一旦这个值达到10000，那么Windows就不再给它更多的窗口，这个过程已经消耗了它的配额。由此引发的异常是“创建窗口句柄时出错”。

原因是Winforms中一个非常常见的编程错误。它通过使用Controls.Remove/At（）或Controls.Clear（）从父项中移除控件时发生，但忘记在这些删除的控件上调用Dispose（）方法。这将使他们永远活着，靠窗把手保持活力。

+1我会深入研究这一点。从我们过去的错误，这听起来*很有希望！ –

在抛出异常的时候不是10,000。 Handles/User Objects/GDI分别为1278/1376/799。 –

发布异常的完整堆栈跟踪。确保启用非托管调试并启用Microsoft符号服务器，以便我们也可以看到本机堆栈帧。 –
