Using the RichEdit 1.0 Control with MFC
The latest version of this topic can be found at Using the RichEdit 1.0 Control with MFC.
To use a RichEdit control, you must first call AfxInitRichEdit2 to load the RichEdit 2.0 Control (RICHED20.DLL), or call AfxInitRichEdit to load the older RichEdit 1.0 Control (RICHED32.DLL).
You may use the current CRichEditCtrl class with the older RichEdit 1.0 control, but CRichEditCtrl is only designed to support the RichEdit 2.0 control. Because RichEdit 1.0 and RichEdit 2.0 are very similar, most methods will work; however, note there are some differences between the 1.0 and 2.0 controls, so some methods might work incorrectly or not work at all.
