======================================================================== ActiveX Control DLL : COLORBTN ======================================================================== ControlWizard has created this project for your COLORBTN ActiveX Control DLL, which contains 1 control. This skeleton project not only demonstrates the basics of writing an ActiveX Control, but is also a starting point for writing the specific features of your control. This file contains a summary of what you will find in each of the files that make up your COLORBTN ActiveX Control DLL. ColorBtn.dsp This file (the project file) contains information at the project level and is used to build a single project or subproject. Other users can share the project (.dsp) file, but they should export the makefiles locally. ColorBtn.h This is the main include file for the ActiveX Control DLL. It includes other project-specific includes such as resource.h. ColorBtn.cpp This is the main source file that contains code for DLL initialization, termination and other bookkeeping. ColorBtn.rc This is a listing of the Microsoft Windows resources that the project uses. This file can be directly edited with the Visual C++ resource editor. ColorBtn.def This file contains information about the ActiveX Control DLL that must be provided to run with Microsoft Windows. ColorBtn.clw This file contains information used by ClassWizard to edit existing classes or add new classes. ClassWizard also uses this file to store information needed to generate and edit message maps and dialog data maps and to generate prototype member functions. ColorBtn.odl This file contains the Object Description Language source code for the type library of your control. ///////////////////////////////////////////////////////////////////////////// ColorBtn control: ColorBtnCtl.h This file contains the declaration of the CColorBtnCtrl C++ class. ColorBtnCtl.cpp This file contains the implementation of the CColorBtnCtrl C++ class. ColorBtnPpg.h This file contains the declaration of the CColorBtnPropPage C++ class. ColorBtnPpg.cpp This file contains the implementation of the CColorBtnPropPage C++ class. ColorBtnCtl.bmp This file contains a bitmap that a container will use to represent the CColorBtnCtrl control when it appears on a tool palette. This bitmap is included by the main resource file ColorBtn.rc. ///////////////////////////////////////////////////////////////////////////// Other standard files: stdafx.h, stdafx.cpp These files are used to build a precompiled header (PCH) file named stdafx.pch and a precompiled types (PCT) file named stdafx.obj. resource.h This is the standard header file, which defines new resource IDs. The Visual C++ resource editor reads and updates this file. ///////////////////////////////////////////////////////////////////////////// Other notes: ControlWizard uses "TODO:" to indicate parts of the source code you should add to or customize. /////////////////////////////////////////////////////////////////////////////
