[LCD]

This a rather simple question for all you studs out there! Please help me
with this. I have a string = "Please help me", and I want to convert this
into it's hex equivalent. How do I do it, I have trying for a couple hours
and can't seem to get my head straight arount this whole conversion things.

TIA, LCD

Not sure exactly what you want to do but check out the Hex Function, Convert
Class, and ToCharArray string method. One or all of these in combination
should get you what you want.

RE: Converting String to Hex

Okay I want to doing something similar to this. In python, there is a
function called "binascii".

So if I type:
###[color=blue][color=green][color=darkred]
>>> binascii.hexlif y('hello world')[/color][/color][/color]

This is the result I get:

'68656c6c6f2077 6f726c64'
###

I want to do something similar in VB.NET or C#. Can someone help?

Dim str As String = "hello world"
Dim byteArray() As Byte

byteArray = System.Text.ASC IIEncoding.ASCI I.GetBytes(str)

RE: Converting String to Hex

I just realized you are probably asking for the ascii values of each
character of a string in hex format. This should do it for you:

Dim str As String = "hello world"
Dim byteArray() As Byte
Dim hexNumbers As System.Text.Str ingBuilder = New System.Text.Str ingBuilder

byteArray = System.Text.ASC IIEncoding.ASCI I.GetBytes(str)

For i As Integer = 0 To byteArray.Lengt h - 1
hexNumbers.Appe nd(byteArray(i) .ToString("x"))
Next

MessageBox.Show (hexNumbers.ToS tring())

The output should be:
68656c6c6f20776 f726c64

RE: Converting String to Hex

Dude, you are genius!

You made it like POC (piece of cake). Now please explain me this, I didn't
quite catch this part:

hexNumbers.Appe nd(byteArray(i) .ToString("x"))

where is this "x" coming from? and why?

TIA, LCD

RE: Converting String to Hex

The Byte structure has several overloaded ToString() methods. The one used
below accepts a string representation of a NumberFormatInf o.

"X" or "x" means the format will be hexadecimal
"D" or "d" means the format will be in decimal, etc.

The below links shows possible formats:
