I'm working on a program to encode and decode base64. I know there's a built-in method, but I want to do it myself to really learn something. My question is: how do I take the ASCII value of a letter and convert it to binary? Please see the second-to-last line.
Dim UserInput As String = txtInput.Text
Dim ASCIIinput(txtInput.Text.Length - 1) As Integer
' convert user input to ASCII numbers
Dim i As Integer
For i = 0 To (UserInput.Length - 1)
ASCIIinput(i) = AscW(UserInput.Chars(i))
' /* starting encoding process */
' take three bytes from the input
Dim i2 As Integer
Dim ByteArray(ASCIIinput.Length - 1) As Byte
For i2 = 0 To (ASCIIinput.Length - 1)
ByteArray(i2) = CByte(ASCIIinput(i2))
' uhh... this just converts it to another 2-digit integer, just like the ASCII number... not an 8-bit binary number
I'm a total newbie here, but I am working through your VB
2005 book ;) Thanks!
