Apologies if this is a noob question, but I've been struggling with this for quite a while...
I'm trying to convert a byte array (encrypted authorization code) into a *screen-printable* string that is displayed in a text box. Once displayed, the text will be copied, transmitted and then pasted (all manually by humans) into a second utility where the string must then be reverse-engineered into the *original* byte array. The byte array will then be decrypted by the second app.
I've got the encryption/decryption piece sorted, I'm just struggling with the screen-printable text bit...
I've tried many of the suggestions posted on the web for converting the byte array into a screen-printable string. All have worked, and I've settled on the following:
Dim Bytes() As Byte = myCrypto.Encryp t("AuthCode") ' .Encrypt returns a byte array
Dim myBitConverter As BitConverter
txtBox.Text = myBitConverter. ToString(Bytes)
' Displayed as XX-XX-XX-XX... in the txtBox.
The problem is that for all of the examples I've found on the internet, none have helped me reverse engineer the screen-printable string into the original byte array. Although I like the BitConverter.To String format (XX-XX-XX-XX) used in the code above, I don't really care how the string looks - as long as it is screen-printable and can be displayed, copied, emailed and pasted without issue. Can you enlighten me as to how I can easily convert a byte array to a screen-friendly string and then back again?
Many thanks in advance.

Will converting it to base 64 be any good to you, like:
mybuffer is your byte array and you write:
Dim data64 As String= System.Convert. ToBase64String( mybuffer, 0, mybuffer.Length )
now "data64" contains a string representation of the byte array. You can type it in a textbox and the other guy can take that string and through the following statement get the original byte array back:
Dim b() As Byte = System.Convert. FromBase64Strin g(data64)
Its sort of what the ViewState in ASP.net does.
Hope that helps.

Hi list,
I am trying to dynamically grow a 2 dimensional array (Atom ***Screen) of
pointers to a struct Atom (i.e. the head of a linked list). I am not
sure if this is the right way to do it:
/* Allocate 1st dimension */
if((Screen = (Atom ***) malloc(sizeof(Atom **) * Width)) == NULL)

I have another problem, maybe it is simple to fix.
I have this:

But I now want to have a second pointer Test2 to point to a location inside

But with no copying.
Something like this.

I need to marshal an IntPtr (which I've got from GlobalLock of an HGLOBAL)
into a byte array. I know the size of the array required and I've got a
pointer to the blob, but I can't see how to copy the memory across.
Using Marshal.PtrStructure doesn't work - it says my byte() array is not
blittable! (byte is a blittable type however). Cannot use Marshal.Copy,
because that works the other way around (for mashalling to COM, not from
it).

Hi all,
Ok, I am not the best C programmer in the world but am looking to
convert a byte array which contains pixel information to a bitmap.
basically i have a screen say 320x280 leading to a 89600 element byte
array eah element specifying the pixel color. I need to convert this
into a Bitmap tho. Does anyone have any ideas on how to do this or
even if there is something already around that can do this for me?

Hi all,
Could some kind soul peruse the following code and see if there is
anything wrong with it?
Its producing output, but its only occupying the first third of the
output array; to give an example, think of a TV screen where only the
top third shows anything, and what is does show is repeated 3 times.
The code should skip through an array of bytes, taking them in groups
of three, and then writing the results of a calculation on the...

Hi,
The subject says it all... I want to use a byte and use it as byte* so I
can increment the pointer to iterate through it.
What is the fastest way of doing so in C#?

Hi all,
I am trying a program to convert floating point values to a byte array
and printing the same to the screen.The idea behind this is we already
have an existing function which can do byte level parsing what ever
may be the type of data.The data would be coming from an external
environment.When I parse int,char at byte level,I get right
values,where as floating point just prints 0.000000 to the
screen.Given below is a sample program...
