Write to hex, is it possible?

Expand Post »

Please let me know if this is possible or even remotely possible! I need to write to a file, but directly to hex. For example, if I write "2D" to the file, i want to be able to open the file in a hex editor and see "2D" in the hex portion, not the ASCII portion. the only way i have been able to get "2D" into the hex portion is by writing "-" to the file.

i have been told this is possible, but so far have come up empty-handed. any ideas, hints, code, or suggestions would be greatly appreciated! Thanks!

Re: Write to hex, is it possible?

What format is the original data in, that you want written to the file? Your hex editor happens to display the stored value in hex format when it reads it. You might equally display it in decimal, or ASCII, or in some other format.

It's not stored as 'hex'.

So use fprintf() rather than printf()

Re: Write to hex, is it possible?

LOL you've opened a thread which is like two years old now. The OP might have already solved this problem by now.

Perhaps, he might have got a far better knowledge than what he had when he started this thread. And you post what information does it gives him anyway???? Try to explain things a bit more clear!!

I'd reported this problem earlier in DaniWeb Community Feedback, but somehow, things didn't work out. Some problem regarding the workload that means for the mods or the work required for automating the 'lock' feature.

It's not. In fact, I believe it's a feature of vBulletin if you choose to enable it.

I don't. It's a good idea in theory, but painfully annoying in practice. Besides, there's no rule against adding to an existing discussion, regardless of how old it is.
