MFC program in VS debug mode, CPropertySheet attribute wizard abnormal? Pray god to see-CodePudding

In VS debug mode, inherited from the CPropertySheet wizard dialog box, click on the button in the properties page, abnormal may write:
Property page to add the source code is as follows:
IMPLEMENT_DYNAMIC (CSuperMaintenance CPropertySheet)

CSuperMaintenance: : CSuperMaintenance (UINT nIDCaption, CWnd * pParentWnd, UINT iSelectPage)
: CPropertySheet (nIDCaption pParentWnd, iSelectPage)
{
The AddPage (& amp; M_SuperICcard);
The AddPage (& amp; M_SuperStart);
}

CSuperMaintenance: : CSuperMaintenance (LPCTSTR pszCaption, CWnd * pParentWnd, UINT iSelectPage)
: CPropertySheet (pszCaption pParentWnd, iSelectPage)
{
The AddPage (& amp; M_SuperICcard);
The AddPage (& amp; M_SuperStart);
}

CSuperMaintenance: : ~ CSuperMaintenance ()
{
}

The button button response function is as follows:
ShowOperInfo (1, "super maintenance - start", 0, 0).
CSuperMaintenance sheet (_T (" "));
Sheet. SetWizardMode ();
Int iRet=sheet. DoModal ();
ShowOperInfo (1, "super maintenance - end", 0, 0).

Dialog initialization example:

 
CRect sheetRect; 
GetWindowRect (sheetRect); 
SheetRect. Top +=40; 
SheetRect. Bottom -=80; 

M_msgSheet=new CPropertySheet; 
M_page2=new CPag2;

//m_page2 - & gt; The Construct (IDD_PROPPAGE_SMALL); 
M_msgSheet - & gt; The AddPage (m_page2); 
M_page3=new CPage3; 
M_page3 - & gt; The Construct (IDD_PROPPAGE_MEDIUM); 
M_msgSheet - & gt; The AddPage (m_page3); 

if(! M_msgSheet - & gt; Create (this, WS_CHILD | WS_BORDER | WS_VISIBLE)) 
{
DWORD err=GetLastError (); 
CString str; 
STR. The Format (" % d ", err); 
MessageBox (STR); 
} 
The else 
{
//m_msgSheet - & gt; ModifyStyle (0, WS_TABSTOP);//no effect? 
//WS_EX_CONTROLPARENT Allows the user to navigate 
//among the child Windows of the window by using the TAB key. 
//you will see "mainDlgButton1" in any page!
