I wrote in OnInitDialog:

CToolTipCtrl m_tip;
	m_tip.Create(this);
	m_tip.AddTool(GetDlgItem(IDC_BUTTON9), _T("Tooltip text"));
	m_tip.Activate(TRUE);

but tooltip doesn't appear..

What I have tried:

I tried to use a pointer fot tip but it's the same thing

You need some steps more to do like, handling the tooltip messages.

Read the CListCtrl and Displaying a Tooltip article and code for the details.

I suspect it may be because m_tip is a local variable, and goes out of scope at the end of OnInitDialog. Try adding the variable to the CDialog class so it remains for the life of the dialog.

Well I was largely guessing as I do not have MFC, and it is quite a few years since I used it.

I solved..I wrote:

BOOL CMFCApplication22Dlg::PreTranslateMessage(MSG* pMsg)
{
m_tip.RelayEvent(pMsg);
return CDialog::PreTranslateMessage(pMsg);
}
