This is really a nice thread and good answer given for the query. Can you kindly detail on each step which would give a detailed overview for all of us.

Sure I am glad to give you all detailed explanation on each of the above steps:

Step 1: Running the ATL COM Wizard
In this first you have to choose the ATL COM AppWizard. Then give a project name and save. Select the Server Type. Then click the finish button which gives you a window New Project Information giving details of files that would be created. Press Ok and proceed to next step.

Step 2: Creating a new ATL object
Click the View menu and choose Workspace. In that click the ClassView tab. In this you will see the classes of the project name you created. Choose this and right click and choose their New ATL Object. From this choose the default Simple Object and on clicking next you would be taken to ATL Object Wizard Properties. Define the properties and proceed to Step 3

Step 3: Adding a method
In the same ClassView tab as detailed in step 2 you would have Add Method. Choose this and add the method you want.

Friends please note that in step1 we have to select the Server Type as Dynamic Link Library as we would be building a Server DLL in our case.
