Sorry your browser is not supported!

I was just wondering when you create a file with "Open to Write", is it possible to read this file into another program language? I'm not sure of the structure when the file is created and was wondering if it is proprietary to DB / DBpro?

Hmm ok I was wondering because I looked at the example for "open to write" and it used "write file" so when I tried to look at the file created, it was garbled.

I had another question. I read from a message thread back in 2003 that random access files weren't possible but in one of the DBpro books it was mentioned that is was possible. Before I go too far I just wanted to get confirmation that it was possible.

Thanks

The file you looked at was probably written as a binary file, and you were likely using a text application to view it. (Notepad, perhaps?)

Random access is not directly supported, and there is no built-in seek or even a concept of position that those things require. That doesn't mean you can't do it, just that you must use the most cumbersome methods to do it using the system provided. It is not at all worth it, unless you are simply skipping bytes....use something from a plug-in....IanM has quite alot of dedicated file I/O in many tasty flavours

You could also use the load dll facility to gain access to Windows, or even C file I/O because they have all the tools you could want, and are much faster, too. The dll kernel32.dll contains Windows file I/O, and the C file I/O is in msvcrt.dll Either one will do.
