在自定义控件中创建子按钮窗口后崩溃
Crash after creating child button window inside custom control
我有一个 MFC 应用程序，它显示一个简单的对话框，其中包含自定义控件自定义创建动态控件窗口。 创建自定义控件的第一个子控件后，应用程序在堆栈溢出后崩溃
这是崩溃后的调用堆栈

始终发送的消息是 528，这是 0x210 = WM_PARENTNOTIFYwParam = 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，如果他们中的任何一个向父级发送任何消息，但没有消息，对话框没有显示，但它的窗口句柄已创建，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，其他孩子没有得到有机会被创造。我跟踪了执行，并在对话框中调用自定义控件的子项的创建方法后发生崩溃。自定义控件是一个数据库导航控件，其中包含用于下一个、上一个、新的、用于输入记录编号的按钮，此自定义控件继承自 CWnd。 它里面的按钮继承自 Button，而 Kubernetes 又继承自 CButton。
更新
问题如下：
当我注册自定义控件窗口类时，我将窗口程序设置为 MFC 窗口Proc ，当 MFC 进程找不到任何方法来吃消息时，它调用了窗口的默认进程，即导致打开递归的 MFC 窗口 Poc，我通过将窗口进程设置为默认进程来修复此问题，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
我更新了答案以包含该问题的解决方案，但为了响应@Michael Walz，我将解决方案添加到此答案中
