To create the Richedit control you must call the LoadLibrary function on the appropriate Richedit dynamic-
link library (DLL) somewhere prior to attempting to create the control. Doing this allows the control to
register its class name. For example, to use a Richedit version 2.0 or version 3.0 control in a dialog box,
you must call LoadLibrary("riched20.dll") prior to attempting to load and initialize the dialog box resource.
