I am writing an app that has to create Excel and Powerpoint files on a un*x machine. It's pretty simple to create Excel format files, and it's quite clear how to create powerpoint format files.
But I can't manage to get how an Excel file inside a Powerpoint file is stored. It seems it's kind of LZW-coded. Is there anyone who can give me a hint on how to create an OLE-Container containing an Excel sheet inside a poerpoint presentation (NOT using ANY Microsoft APIs or VBA parts!) ?
