The information in this article applies to:

Microsoft FoxPro for Macintosh, version 2.5b

SUMMARY

FoxBASE+ for Macintosh picture fields must be converted to general fields before they can be viewed in FoxPro for Macintosh. Although the FB+Migration application (FoxPro:Goodies:FB+Migrate:FB+Migrate.App) converts FoxBASE+/Mac picture fields to general fields, you may prefer to perform this operation programmatically, as described below.

MORE INFORMATION

The following code shows how to convert a FoxBASE+/Mac database with a picture field to a FoxPro database with a general field. NOTE: This program can be run only in FoxPro for Macintosh.

   CLOSE DATABASES
   * Prompt for Database to convert
   filename=GETFILE("DBF","Please locate your FoxBase+ database:")
   * Be sure user has selected a database to convert
   IF EMPTY(filename)
      WAIT WINDOW ;
        "No Database Selected to Convert--program terminated" NOWAIT
      RETURN
   ENDIF
   * Open selected database
   USE (filename)
   basename=ALIAS()
   COPY STRUCTURE EXTENDED TO temp
   SELECT B
   USE temp
   LOCATE FOR field_type="P"
   IF NOT FOUND()
      WAIT WINDOW "No picture fields found--program terminated" NOWAIT
      USE
      DELETE FILE temp.dbf
      RETURN
   ENDIF
   DO WHILE FOUND()
      REPLACE field_type WITH "G"
      CONTINUE
   ENDDO
   SELECT field_name FROM temp ;
     WHERE field_type="G" INTO ARRAY fieldlist
   USE
   * Prompt for name of converted database
   fpmgen=PUTFILE("Enter new database name:","PICTURE.DBF","DBF")
   IF EMPTY(fpmgen)
      WAIT WINDOW ;
        "No New Filename Selected--program terminated" NOWAIT
      RETURN
   ENDIF
   CREATE (fpmgen) FROM temp
   DELETE FILE temp.dbf
   APPEND FROM (filename)
   GO TOP
   DO WHILE NOT EOF()
      FOR x=1 TO ALEN(fieldlist)
         APPEND GENERAL (fieldlist(x)) ;
           FROM MEMO (basename+"."+fieldlist(x))
      ENDFOR
      SKIP
      SKIP IN (basename)
   ENDDO
