I have to CRichEditCtrl controls in a dialog window with multiple tabs which开发者_如何学运维 might display the same file.

If you are using CPropertySheet and CPropertyPage for multiple-tab support, you may override CPropertyPage::OnSetActive and CPropertyPage::OnKillActive. Set the current text in OnKillActive and set the same text for other tab that is going to be active (in OnSetActive).
