Scorpion,
Define "character" as in your other post you mention F7, do you mean
keyboard character F7 or the byte F7 as a ANSI or Unicode code point?
You can use System.Convert.ToByte, ToInt16, ToInt32, & ToInt64 to convert a
string into a Byte, Short, Integer, or Long. You may need a loop to convert
grouping of characters into individual Bytes, Shorts, Integers, and Longs...
Then using the System.Text.Encoding you can convert the above Byte (or array
of Bytes) into a string...
Hope this helps
