Hello! Hope someone could help me on converting ASCII characters to Binary
Also,hope you know how to convert Boolean Number to Octal or Hexadecimal or Decimal number.
Thanks in advance!

Hi rattlesnake,
ASCII can only represent character codes between 0 and 127.
About converting ASCII characters to Binary,
e.g. convert AscII value 66 of characterBto Binary like this:
Code Snippet
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports System.Text
Friend Class Program
Shared Sub Main(ByVal args As String())
Dim myChar As Char = "B"c
Dim j As Integer = 0
Dim ascii As Integer = System.Convert.ToInt32(myChar)
Console.WriteLine("ASCII:" & ascii)
Dim binTempResult As String = ""
Do While ascii > 0
j = ascii Mod 2
binTempResult &= j.ToString()
ascii = ascii \ 2
Loop
'reverse output
Dim arr As Char() = binTempResult.ToCharArray()
Array.Reverse(arr)
Dim binResult As String = New String(arr)
System.Console.Write(binResult)
Console.Read()
End Sub
End Class
The output will be:
ASCII:66

By means of Convert class,you can firstconvert Binary to Decimal Intger, and then convert Decimal to Octal and Hexadecimal string.
Code Snippet
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports System.Text
Friend Class Program
Shared Sub Main(ByVal args As String())
Dim bin As String = "1000001" 'Binary string
Dim decimalValue As Integer
Dim hexValue As String
Dim OctalValue As String
decimalValue = Convert.ToInt32(bin, 2)'Firstconvert Binary to Decimal Intger
Console.WriteLine("Decimal:" & decimalValue)
OctalValue = Oct(decimalValue) 'Convert Decimal to Octalstring
Console.WriteLine("Octal:" & OctalValue)
hexValue = Hex(decimalValue) 'Convert Decimal to Hexadecimal string
Console.WriteLine("Hexadecimal:" & hexValue)
Console.Read()
End Sub
End Class
The output will be:
Decimal: 65
Octal: 101
Hexadecimal: 41

This looks like a simple question, but it's a little confusing. Ascii characters are binary - they just happen to be an agreed upon representation of written characters.
My question is... what kind of conversion are you looking for? What are you trying to accomplish? |

Boolean value is either True or False.
You only need to conver True to 1 and False to 0.
The Octal or Hexadecimal or Decimal numbers of the 1/0 arealways 1/0.
If we misunderstood you, please let me know. |

Martin,
This is not necessarily true across all Microsoft languages. Please see System.ConvertoBoolean(Object)
Although the OP's questions aren't particulary clear...well...who knows how much depth is behind them.
Please have a good evening. |

Hi Renee,
Thank you again!
I'm in China, now it's daytime. Have a good evening to you.
Hi rattlesnake,if you still have any doubt and concern about this case, please clarify your questions.
Thanks,
Martin
