发送的消息总是 528 这是 0x210 = WM_PARENTNOTIFY wParam = 77594625，lParam = 3409408

我不知道这是什么原因，以及如何阻止它，我搜索了孩子是否有任何人向父母发送任何消息，但没有消息，对话框没有显示，但它是窗口句柄已创建，自定义控件也有一个句柄，它的第一个孩子有一个句柄，然后我们陷入崩溃，其他孩子没有机会被创建。我跟踪了执行情况，发现在对话框内调用自定义控件的子控件的 create 方法后发生了崩溃。自定义控件是一个数据库导航控件，包含下一个、上一个、新建、编辑以输入记录号的按钮，此自定义控件继承自 TControl，而 TControl 继承自 CWnd。它里面的按钮是从 TButton 继承的，而 TButton 是从 CButton 继承的。

更新

问题如下：

当我注册自定义控件窗口类时，我将 windowproc 设置为 MFC windowProc ，当 MFC proc 没有找到任何方法来吃消息时，它调用了窗口的默认 proc，即 MFC windowPoc 导致打开递归，我通过将窗口 proc 设置为默认值来解决这个问题，如下所示

WNDCLASS wndClass;
//fill the window class data
wndClass.lpfnWndProc = ::DefWindowProc;//AfxWndProc;//this fixed it

解决了我的问题

【问题讨论】：

您的堆栈转储看起来好像正在进行一些递归，因此您得到一个堆栈溢出。是的，它是一个***，来自递归发送相同的消息，现在我发现了我犯的致命错误，我将它作为我的问题的更新发布不要将其发布为未更新您的问题，而是回答您自己的问题。 @MichaelWalz ：我添加它来回答 【参考方案1】：

我更新了答案以包含该问题的解决方案，但作为对@Michael Walz 的回应，我在此答案中添加了解决方案

WNDCLASS wndClass;
//fill the window class data
wndClass.lpfnWndProc = ::DefWindowProc;//AfxWndProc;//this fixed it
that fixed my problem
