MFC extension and OCX

Source: Internet
Author: User

Similar to MFC itself, MFC extension is a group of VC ++ classes built on the MFC class library, ocx (OLE/Active X control ), it is a 32-bit control that replaces 16-bit Visual Basic extension (vbx). ocx is based on Microsoft's object embedding and Connection Technology (OLE ), this technology allows Binary-based object interface interaction, so ocx has a completely different concept from the MFC extension, "MFC extension isCode-Level and compile-time user interface. ocx is a binary-level and runtime user interface ."
