Dear Sir or Madam
I am Miss.song, writing to take about problem which is Microsoft Powerpoint 2003 and 2007 compatibility.
I, as a programmer in Document converting work, am developed Microsoft Powerpoint Document converter into my program. But, recently, I have a problem which is from saving 'ppt' format document in Microsoft Powerpoint 2013 to loading that file into Microsoft Powerpoint 2003. And after editing something, to resave work take in there. Next, I reopen that file into Microsoft Powerpoint 2013.
But, the big problem has been happened to unvisual or something wrong data, for example, disappear color atrribute, show previous information and so forth. I am tring to solve this problem, currently I understand that is related to checksum information, but not correctly. As result, I don't advance any more because I dont' know what is open between XML data and binary data in PPT file.
So, I would like to need to your help how about opening data correctly.
I look forward to your reply.
Best wishes,
Miss.Song
