Code Generated by the Snap-In Wizard

Once you have determined the name and options for your snap-in object, the Snap-In wizard generates the necessary files and adds them to the existing ATL project.

Every generated snap-in object is implemented with three files. For this discussion, MySnapIn is the short name of the snap-in and the default options are accepted. The generated files are as follows:

• MYSNAPIN.CPP

  Defines the GUIDs used by data members of the snap-in data class (CMySnapInData).

• MYSNAPIN.H

  Contains the declarations for the five classes that implement the ATL snap-in object (in this case, MySnapIn):

  Class	Implements
  CMySnapInData	Data class of the snap-in
  CMySnapInComponent	Icomponent interface
  CMySnapIn	IcomponentData interface
  CMySnapInAbout	IsnapInAbout interface
  CMySnapInPage	Property page of the snap-in

  
  
• MYSNAPIN.RGS

  Registers the snap-in object with the operating system upon the first usage.
