Adding, Editing, or Deleting Controls
Using the Dialog editor, you can add, resize, edit, and delete controls in dialog boxes. You can also edit the properties of a control, such as its ID, or whether it is initially visible at run time.
You can use the shortcut menu in the Dialog editor to quickly add registered ActiveX controls to a dialog box, and you can add ActiveX controls to the Toolbox for quick access (for more information, see Customize Toolbox Dialog Box).
