Hi Devs,

I have an MDI MFC application, I have one child frame window. I have added a caption on title bar by custom paining. its a icon that I have added in titlebar, that icon is treated as button. I need to show tooltip on this button.


How can I do this.I am looking how can I do in MDI based application in MFC specially with custom caption in titlebar where I need to pass Rect parameter of Icon on which I want tooltip.

Please help.

I am aware of CTooltip class and know how to use for dialog based application.
I understand that I need to call CToolTipCtrl::RelayEvent( lpMsg)in PreTranslateMessage like below.

CAboutDialog::PreTranslateMessage(MSG* pMsg)
{
if (NULL != m_pToolTip)
m_pToolTip->RelayEvent(pMsg);

return CDialog::PreTranslateMessage(pMsg);
}



I am not sure how and where I need to write above code in MDI application.

Regards,
Joy
