Hi Chrebtov,
Essential Edit is a purely .NET control written in C#. Like any other .NET control you would have to wrap in an ActiveX wrapper to be able to use it in a MFC environment. Though this is theoritically possible, it could lead to issues that are very hard to resolve. The following articles may be of help here :
Exposing .NET Framework Components to COM
.NET Framework 1.1 Provides Expanded Namespace, Security, and Language Support for Your Projects
Please let me know if you need any other information. We appreciate your interest in Essential Edit.
