For instance, you can link an ActiveX control to a Word document and save that file. However, when you convert that Word document to another format, the link reference to the ActiveX control might not convert into that file format. Therefore, conversion of files that have links to ActiveX controls may not be supported for all file types, partly because not all file types can support ActiveX control linking or activation. For files with links to ActiveX controls, it is necessary to accept and activate the ActiveX control prior to converting the file to another file type that supports ActiveX linking and activation. If the ActiveX control is not activated, the link reference is dropped from the file and will not appear in the converted file.
