Converting to a char array is simple.

Dim s As String = "Hello World"
Dim x As Char() = s.ToCharArray()

I don't know if there is a way to convert a whole string to hex, but you can loop through the character array and convert the integer values of the characters.

Convert to hex using escaped characters:

Dim s As String = "Hello World"
Dim x As Char() = s.ToCharArray()
Dim i As Integer = 0
For i = 0 To x.Length - 1
Console.Write("%{0:x2}", AscW(x(i)))
Next

Convert to hex using non-escaped characters:

Dim s As String = "Hello World"
Dim x As Char() = s.ToCharArray()
Dim i As Integer = 0
For i = 0 To x.Length - 1
Console.Write("{0:x2}", AscW(x(i)))
Next

Convert a string into hexadecimal means convert it to a byte array I think. This can be done very easy with:

System.Text.ASCIIEncoding.ASCII.GetBytes(<stringToConvert>)

This method returns a byte array.

The Hex function does the opposite thing. Converts an hexadecimal value to a String representation of the value

timbo, what your doing is what im looking for, only you print it into a console window. instead i would rather form a string of the 2-"digit"-value hex

for example, a string "expertsexchange" i want to return the value '6578706572747365786368616e6765'

which is just hex...but that arg0 in console is what is allowing me to format the text
