Re: Problem in Rfile

If you have simple and less operations on file then you can use RFile. Google for RFile and you will find many links which talks about RFile. If your app does heavy read/write operations then you can go for stores.

Cheers,

Re: Problem in Rfile

I read all documents but there is no any method for removing(or overwriting) the previous data.

Thanks

Overwriting is simple: You re-position with the help of RFile::Seek() and write. Whatever was there before at that particular position in the file will be overwritten. Thus no need to "remove" something first.
