CPropertySheet in a CFormView

I have run into a problem embedding a CPropertySheet into a CFormView as a child window. What I am doing is implementing a "find" view window, kind of like the find dialog in Windows 95.

I basically create the CPropertySheet as a child window of my view and then add my property pages. In addition, I have a few controls that are part of the underlying CFormView too. Things work fine when I compile for Win 3.x but I get an exception under Win32. The exception cannot be ignored, my application basically crashes.

I am using MSVC 4.2b and I get the exception in CPropertySheet::Create() on the following line:

HWND hWnd = (HWND)PropertySheet(&m_psh);

Any ideas?

That is not very informative. There might be something else which is going wrong during the creation of your property sheet. Please show me the code in detail.

There is a CPropertySheet as a member of my derived CFormView class.

CPropertySheetView::CPropertySheetView(UINT nIDTemplate) :
      CFormView(nIDTemplate)
{
  m_PropSheet = new CPropertySheetEx(AFX_IDS_APP_TITLE, this, 0);
}

int CPropertySheetView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
  if (CFormView::OnCreate(lpCreateStruct) == -1)
    return -1;

#ifdef WIN32
  DWORD dwSheetStyle = DS_MODALFRAME | DS_SETFONT | WS_CHILD | WS_VISIBLE | WS_TABSTOP | DS_3DLOOK | DS_CONTEXTHELP;
#else
 // The WS_SYSMENU style is needed because the 16-bit MFC
 // property sheet
 // class looks for a system menu.
  DWORD dwSheetStyle = DS_MODALFRAME|DS_SETFONT|WS_CHILD|WS_VISIBLE|WS_TABSTOP|WS_SYSMENU;
#endif

 // This causes the following error under win32.
 // "First-chance exception in Nman32.exe: 0xC0000005: Access Violation."
 if (!m_PropSheet->Create(this, dwSheetStyle))
    return -1;

 // Assign an id to the property sheet window.
  ::SetDlgCtrlID(m_PropSheet->m_hWnd, IDC_PROPERTYSHEET);

  return 0;
}

Using a standard CPropertySheet as a child control can cause
problems (as admitted by Microsoft).  Try subclassing from
CPropertySheet and set its style to WS_EX_CONTROLPARENT.  This
fixes a focus bug in property sheets.

See "www.microsoft.com/kb/articles/q149/5/01.htm" for specific
instructions.

Create your CPropertySheet based window without a parent. Once, it is created successfully use SetParent() , to make the property sheet of the FormView.

Neither of the above ideas worked! I have decided to scrap the idea of making a property sheet a child of my view. Instead, I think the better approach for me is to embed a CTabCtrl and do my own property pages. This will work better because I still had tabbing problems with the proeprty sheet approach.
