Hii

I have been converting a file into its hex value.But cannot convert it back into same exe value

Let me get in detail

Here is the code

Imports System.IO

Sub Main()


 


        Dim fileName As String = "ABC.exe"


 


        Dim data As Byte() = File.ReadAllBytes(fileName)


 


        Dim fs As FileStream = File.OpenWrite(fileName & ".txt")


        Dim sw As StreamWriter = New StreamWriter(fs)


 


        Dim pos As Integer = 0


        Dim line As Integer = 0


 


        While pos < data.Length


            sw.Write(String.Format("{0}:", line.ToString("0000")))


 


            For i As Integer = 1 To 20


                sw.Write(String.Format(" {0:x2}", data(pos)))


                pos += 1


                If pos = data.Length Then


                    Exit For


                End If


            Next


 


            sw.WriteLine()


            line += 1


        End While


 


        sw.Flush()


        sw.Close()


        fs.Close()


    End Sub

Now,When i call the main method an text file called ABC.exe.txt is generated.

First of all instead of ABC.exe.txt can we have ABC.txt only

and secondly can how can i convert this hex values back to exe.. at least compile it in vb or any other language

Thank you for your time

What are you trying to accomplish? I mean, it looks like you're trying to emulate a primitive hex editor, but I'm not really sure. Modifying the hex for a .exe is almost guaranteed to result in a non-functioning program.
