How to add a tool tip to control in window application (win32 API) using Visual C++ 2008.

I have a window application (win32 API) in visual C++ in which I have to add tool tips to the control button. Can any one help me out in achieving the above task? Thanks in advance.

If you don't use MFC classes see About Tooltip Controls

Here is an example using CToolTipCtrl class,

// Init a tooltip window    
m_ToolTipCtrl = new CToolTipCtrl;
m_ToolTipCtrl->Create( this ); // 'this', usually a CDialog window

m_ToolTipCtrl->SetMaxTipWidth( 300 ); // if you need multiline messages
m_ToolTipCtrl->SetTipBkColor( 0x000000 );
m_ToolTipCtrl->SetTipTextColor( 0xe0e0d0 );

// Attach a CListBox control (we can attach many controls)
m_ToolTipCtrl->AddTool( plstBox, "Hey, i am a tooltip message!" );


// ...
// (*) We must use the following in order to use tooltips (MFC 4.0 and later versions)
BOOL MyDialog::PreTranslateMessage(MSG* pMsg) 
{
    if (NULL != m_ToolTipCtrl)
        m_ToolTipCtrl->RelayEvent(pMsg); // <- listen mouse messages!


    return CDialog::PreTranslateMessage(pMsg);
}
