B64 on PB works worry free !

If Base64Decoder expects a string I would need to make a str=PeekS copy from the buffer? wouldnt be good with large attachments (slower + duplicated memory), especially with base64 sizes being +33% ?

If you need to decode big attachments, you could build you own high speed decoder. The Base64 specification is not that complicated.
For small attachments, the impact on memory and speed probably isn't that big.

Allocation and copy will probably not matter compared to the decode/encode operation. You shouldn't worry on such micro optimisation nowaday, modern OS provides extremly fast alloc and block copy operations.

Fred wrote:Yes, that's it. It would be something like that:

Code: Select all

Result = Base64Decoder(Input$, *OutputBuffer, OutputSize)
Result$ = Base64Encoder(*InputBuffer, InputSize [, Flags])

I see. That would make Base64 encoding and decoding simpler.

My customers deserve the best though, I won't have them waiting extra time just for my app to make a duplicate copy of a large buffer just to convert it to a string type because i'm too unprofessional to use an existing buffer! but I understand if it will make use of the function easier for beginners albeit at the expense of flexibility, so I will look to use other base64 decode functions, i know there are fortunately several existing implementations PB'ers have posted over the years which probably already fit the bill so we're probably already spoiled for choice!

Awww, everyone selling a product should have a sign like that at the office and probably inside their fridge too.

Some signs at one of my actual workplaces:

Our customers deserve the best - so what the hell are you doing here?

Great work! Thanks for the Mac OS X fixes!!!!

With Windows XP in Virtual Machine I get an error because the compiler could not be loaded....
This installation was copied as a zip archive to the Virtual Machine after installing and zipping on an other machine. I had never problems before with that routine....

A new quick fix version has been pushed on the server. If you already downloaded before this post, please download it again, sorry for the inconvenience !

Thanks for the SQLite update to latest v3.13.0

Fred, why does PB 5.50 create a folder in my Temp directory every time I compile/run??

I currently have 158 folders called "PureBasic#######"
They are only ~1 MB each, but it seems like extra clutter.

Same problem here with XP. The Temp directory is full of PB subfolders... and the "no compiler loaded" error in the virtual machine persists...

Hi Fred,

I just noticed this update and am reinstalling. I have subscribed to this thread as well. Is there where beta 3 will be "announced" as well? Or will it be a separate thread?

Cheers!

hi Fred,

thanks for All. I love to use PB at work or for my pleasure. But Pleeeeeeeeeeeeaaaaaaase ! Add Proxy support to http lib ! Some solution (curl or my own http include file) can't be used if we want to make a module.

Pity ! Pity ! Pity !
