I need to display different messages which dinamically change and are not set in resources.  I need to do this when mouse pointer moves over a certain area of a dialog.
I declare local CToolTipCtrl variable, create tool tip control and than I try different ways to display my message; unsuccessfuly.

I'd appreciate any suggestions.

Use AddTool/UpdateTipText to change the text.  You can pass a string or resource id.  This function is overloaded (there are 2 versions : look it up in the help)

Presumably you are doing the relay events stuff

The steps are :-
1. Add tooltip member variable (CToolTipCtrl) to your dialog class, say m_ToolTip
2. OnInitDialog do
      // set tooltips
      m_ToolTip.Create (this);
            m_ToolTip.Activate (TRUE);
            m_ToolTip.AddTool( &m_btnPrev, IDS_TTPREV ) ;
            m_ToolTip.AddTool( &m_btnNext, IDS_TTNEXT ) ;
            m_ToolTip.AddTool( &m_btnFirst, "Some Text" ) ;

The first parameter of the control is the CWnd (or derived from CWnd - example:CButton,CEdit etc) from the control you want to associate the tip with, second is the resource id, or there's an overloaded version of AddTool which takes a string parameter

3. PreTranslate message
BOOL CTComply::PreTranslateMessage(MSG* pMsg)
{
    if (m_hWnd)    
      {
        m_ToolTip.RelayEvent (pMsg);
            return CDialog::PreTranslateMessage(pMsg);
      }
    return (FALSE);
            
}


4. For an area on a dialog containing no visible controls, I suggest you create  a dummy static control at the correct location, and bind a CStatic member variable to it.  If the dummy control has no text, it will be invisible to the user, so it will look like the tooltip comes from the dialog background.

You can set text of tooltips dynamically at runtime in a TTN_NEEDTEXT message handler.

hope that helps
