Adding property pages

Adding property page objects to your project

To add a property page for your items:

• In the Delphi menu, select File->New->Other.

• On the Namespace Extensions tab, select Shell Extension Property Page.

The property page is now created and added to your project.

The property page contains a form that you populate in design mode, like you are used to for any Delphi forms.

Implementing functionality

Implement the following functions for your property page:

• procedure InitializeFromData; override;
  This is called to allow you to populate your property sheet from internal data.

• procedure SaveChanges; override;
  This is called to allow you to update internal data from your property sheet.

• procedure ApplyChanges; override;
  This is called in response to the user hitting the apply button.

• procedure DiscardChanges; override;
  This is called when the user hits the cancel button.

• procedure ShowHelp; override;
  This is called when the user hits the help button.

• function Valid : boolean; override;
  This is called so that you can indicate whether the user entered data on your form is valid.  You should show a message box and return false if it is not.
