Determine the Document Format

To determine a document format

  1. Open the document. See Open and View a Document.

    To get format information without viewing the document, set the VAPIDF_FLAGS_OPEN_VAPI_ONLY flag in the nFlags member of the TPVAPIOpenDocumentInfo structure.

    To quickly determine a document’s format, regardless of whether the document is supported for viewing, set the VAPIDF_FLAGS_OPEN_FORMAT_ONLY flag in the nFlags member of the TPVAPIOpenDocumentInfo structure. Only the VAPIM_INIT message with the VAPIMWP_INIT_GETDOCFORMAT parameter is supported when opening a document with the VAPIDF_OPEN_FORMAT_ONLY flag enabled.

  2. Use the VAPIMWP_INIT_GETDOCFORMAT parameter of the VAPIM_INIT message to get the document format of the currently opened document.

  3. Use the VAPIMWP_INIT_GETDOCCLASS parameter of the VAPIM_INIT message to get the general class to which the currently opened document belongs.
