   I have an Dialog Based App. with TabCtrl Pages in it, if I
set the focus to a ListCtrl from a Page, and I press ESC, the
current Page from TabCtrl is cleared, and all the controls
from the page disappears...

Please, if someone could tell me what can cause this thing to
happen...

					Thanks.

In your derived class add:

void CMyDlg::OnCancel()
{
  // Do nothing.
  // _NOT_ to call CDialog::OnCancel() with EndDialog().
}

Mario,

Try overriding OnOK() and OnCancel() from your tabpage and put
nothing in them, like:

void CMyPage::OnOK()
	{
	// Do nothing
	}

void CMyPage::OnCancel()
	{
	// Do nothing
	}

Good luck,
-Quang

Hi Mario Mercea,
	I think you have pasted a child dialog onto the tabs of the
	TabCtrl... If so OnOK and OnCancel gets called when you
	press RETURN or ESC key when the dialog has got focus.
	The default processing of OnOK or OnCancel is to unpop the
	dialog.... and so this disappearing pages. To avoid this
	one possible soultion is to override OnOK and OnCancel and
	do nothing in it (dont even call the default processing).

	Hope this helps.

regards & bye
- Antony

The ESC key is probably translated into Cancel message. Check your
accelerator table to see if it is the case.

[Moderator's note: I thought this was done without the accelerator table.]
