OLE (Object Linking and Embedding) objects are active links in your project to documents created and edited in other applications. This enables you to insert formatted objects that you cannot create directly in the Help+Manual editor, such as formulas created in the MS Equation Editor.
OLE objects can be inserted as links to external files (recommended) or as links to objects that are actually embedded in your project file. Embedded objects are stored with your project and will increase its size.
When your help file is published, OLE objects are converted into static bitmap graphics. The advantage of OLE over screenshots is that the objects remain editable. Double-clicking on an OLE object in the Help+Manual editor opens it for editing in its associated program.
Please see About using OLE objects in the Reference section for some important additional information.
