What can cause Warning: calling DestroyWindow in CDialog::~CDialog -- OnDestroy or PostNcDestroy in derived class will not be called.

After closing my app the debugger reports this warning: Warning: calling DestroyWindow in CDialog::~CDialog -- OnDestroy or PostNcDestroy in derived class will not be called. Any ideas what can cause this? What can I be doing wrong? What should I look for to correct this? Thanks.

You're probably deleteing a modeless CDialog without first calling its DestroyWindow(). /ravi Let's put "civil" back in "civilization" http://www.ravib.com ravib@ravib.com

Ravi, Thanks for the feedback. I think these are being caused from property pages of a property sheet. Does this make sence? If so how do I correctly delete pages from a sheet? Thanks!

Is your CPropertySheet class modeless? Or, do any of your property pages display modeless dialogs? Or both? /ravi Let's put "civil" back in "civilization" http://www.ravib.com ravib@ravib.com

Ravi, Thanks again for a reply. It is a complicated app. It is MDI using doc/view model. The veiw of the doc/view is split (with a splitter). One pane of the splitter is a view where I create the property sheet and the property pages. So, they are modeless as I can filp thru the pages and do work in the other panes of the split view.

When you close the view, make sure you call the property sheet's DestroyWindow(). This should take care of the problem. When the view gets created, do:

m_pPropSheet = new CMyPropSheet (...);
ASSERT (m_pPropSheet != NULL);
m_pPropSheet->AddPage (...);
m_pPropSheet->AddPage (...);
m_pPropSheet->AddPage (...);

When the view gets destroyed, do:

ASSERT (pPropSheet != NULL);
m_pPropSheet->DestroyWindow();
delete m_pPropSheet;
