Hi,

I am trying so hard to busy myself after a messy breakup and one of the things I've chosen to do is program a bit. I was wondering if it is possible for DB Pro to modify files binary information. If it was, then I could use the idea to encrypt information and decrypt it. I wont explain how I would do this, as it wouldn't be much of an encryption, but an answer to my question would be much appreciated

Also, does anyone else have any idea for useful programs which can be made? I am a reasonably experienced programmer and will most likely create any program idea which appeal to me

Thanks,

Arenas

Hi Arenas,

It is possible to use binary operators with DBP:
- <<, >> for bit shifting
- && (AND)
- || (OR)
- ~~ (XOR)
- .. (NOT, %1111 .. %1010 becomes %0101)
And it is also possible to read a file byte per byte.

But it is not possible to load a file from RAM memory (like images, or objects), but I think IanM's Matrix Utils will offer you a solution for this. It believe it has commands to construct media from raw data.

Cheers!
Sven B

I agree with Sven B. IanMs Matrix 1 Utilities Plugin is a must-have if you want better file manipulation than the default methods in Darkbasic Pro.

Get it and check out his datafile commands:

Actually, a file mapped into a memory bank may be a better choice than datafiles.
