如圖，我想要在基于對話框的MFC程式實作可停靠的浮動視窗。現在實作的情況是：在主對話框呼叫派生自CFrameWndEx的MainFrame類然后create。然后主對話框、MainFrame同時都在，
這時候應該把主對話框隱藏了還是把MainFrame貼到主對話框里？請問該怎么做？因為主對話框還要做別的控制元件操作之類的。
還有這種情況關閉程式會報很多錯，該怎么辦？

這個功能有沒有大佬實作過？可不可以給個原始碼學習下啊？

這是我上一篇帖子，自己回復不了了，所以另外開新帖
uj5u.com熱心網友回復：
還是我本來這種想給基于對話框加浮動視窗的想法就是錯的？uj5u.com熱心網友回復：
那個 CMyframe 的父視窗是 對話框 。大小要 小于 對話框 ！uj5u.com熱心網友回復：
if (!m_mainFrame.Create(NULL, _T("TEST"), WS_OVERLAPPEDWINDOW, CRect(0, 0, 100, 100)))
{
TRACE0("未能創建輸出視窗/n");
return FALSE;
}
請問這個CMyframe的Create怎樣創建成子視窗呢？
uj5u.com熱心網友回復：
m_pMyFrame = new CFrameWnd;m_pMyFrame->Create(0,"", WS_CHILD, rc, this);
uj5u.com熱心網友回復：
CRect rectDlg;
GetClientRect(rectDlg);
MainFrame *m_pMyFrame = new MainFrame;
m_pMyFrame->Create(0, _T(""), WS_CHILD, rectDlg, this);
m_pMyFrame->ShowWindow(SW_SHOW);
我這樣之后成功了
但是當我拖動視窗第二次的時候程式中斷了（拖動、雙擊停靠、再拖動、再停靠這樣正常；只有拖動一次后再接著拖動一次就中斷了），大佬幫忙看看
然后除錯資訊是
