Is this a string of binary digits?

01001000 01100101 01101100 01101100 01101111 00100000 01010111 01101111 01110010 01101100 01100100

Or a binary representation of 11 bytes?

I am trying to make an app that converts like this http://www.roubaixinteractive.com/PlayGround/Binary_Conversion/Binary_To_Text.asp

So what ever that is

Be sure to strip the spaces before you run it through the grinder.

My output for your string was

Line 50: Output = Hello World

EDIT:

This is my attempt at translating to MASM, should work but might need some correcting

Hi,

I saw the link in your post above and thought you were trying to convert binary represented as a string of 0 and 1 characters into useable ascii text. For example the message in your link decodes as:

Be sure to drink your Ovaltine.

In order to execute the routine, use the following:

invoke StripSpaces,offset String1,offset StringOut
invoke ScanBytes,offset StringOut,offset Output


Works like a charm here.

Yap I made an error trying to format it  ::)

It works like a charm!!!!  :greenclp:
I translate Perfect!!!
Thanks Donkey  :biggrin:

I took the Binary Message that site had and it converted it Perfect !!!

Any time, it was an interesting problem. Hockey is about to start, damn those Russians for not living in a decent time zone. Anyway USA vs Czech Republic so I'm shutting it down...

Just woke up after staying up till nearly 5am watching the US kick the Czech Republic's arse. Had a buddy who drove a semi for Timmy's, used to get cases of coffee for free. The stuff is the crack cocaine of coffee, I'm completely at it's mercy.

Weird, I didn't have any problems with it here at all.

i am writing my own - lol
this is what i'm using for a test string...
szTest      db '1001000 1100101 1101100 1101100 01101111 100000 01001000011001010110000101110100011010000110010101110010',0

might be the leading 0 - i will play with it, later

Dave,
01001000011001010110000101110100011010000110010101110010 is a 56-bit sequence - how do you want it to be interpreted?
