To copy a part (or class) between applications, copy the part and then move the new part to a different application. If you're copying a visual or nonvisual part, generate archival code for the part into a separate application before copying it.
Copying the part
To copy the part:
A window opens, asking if you want to look at scripts (methods) which use the part you're copying.
Moving the part
To move the new part to a different application:
A window opens, listing applications to which you can move the part. These applications have all the prerequisites that the part needs to function.
If you don't have any applications that can receive the part, a message box informs you that the part can't be moved. Because you added the target application as a prerequisite, it should be in the list.
