First you will create the initial ATL project using the ATL COM AppWizard.
Your dialog box should look like this:
Click OK and the ATL COM AppWizard presents a dialog box offering several choices to configure the initial ATL project.
Because you are creating a control leave the Server Type as a DLL, since a control must be an in-process server. All the default options are fine, so click Finish. A dialog box appears that lists the main files that will be created. These files are listed below, along with a description of each file that the ATL COM AppWizard generates.
To make the Polygon DLL useful, you need to add a control, using the ATL Object Wizard. Send feedback to MSDN. Look here for MSDN Online Resources. © 1999 Microsoft Corporation. All rights reserved. Terms of use.Step 1: Creating the Project
File
Description
Polygon.cpp
Contains the implementation of DllMain, DllCanUnloadNow, DllGetClassObject, DllRegisterServer and DllUnregisterServer. Also contains the object map, which is a list of the ATL objects in your project. This is initially blank, since you haven't created an object yet.
Polygon.def
The standard Windows module definition file for the DLL.
Polygon.dsw
The project workspace.
Polygon.dsp
The file that contains the project settings.
Polygon.idl
The interface definition language file, which describes the interfaces specific to your objects.
Polygon.rc
The resource file, which initially contains the version information and a string containing the project name.
Resource.h
The header file for the resource file.
Polygonps.mk
The make file that can be used to build a proxy/stub DLL. You will not need to use this.
Polygonps.def
The module definition file for the proxy/stub DLL.
StdAfx.cpp
The file that will #include the ATL implementation files.
StdAfx.h
The file that will #include the ATL header files.
