2.9.278 SttbfAutoCaption

Office

The SttbfAutoCaption structure is an STTB that contains AutoCaption information. Each string is the ProgID of an OLE object that, when inserted into the document, automatically has a caption inserted with it. The extra data which is appended to each string is an unsigned 16-bit integer that specifies a zero-based index into SttbfCaption. The data at that index defines the caption that is inserted.
