I want to convert Hexadecimal or normal integer to Binary. Does VB.Net has function to do that? I only found Hex function that convert normal integer to Hexadecimal. 6 43660
MrKrich,
You can use Convert.ToInt32 to go from a string to an integer.
You can use Convert.ToStrin g to go from a integer to a String.
Both support both Hex & Binary, as well as octal & decimal (2, 8, 10, or 16
from base)
Dim s As String = "fab4"
Dim i As Integer = Convert.ToInt32 (s, 16)
Dim s2 As String = Convert.ToStrin g(i, 2)
Dim i2 As Integer = Convert.ToInt32 (s2, 2)
Hope this helps

Try is code. Is takes the text from TextBox1
and converts it into a string of 1's and 0's that
represent the binary code of the number.
Dim from As Int32
If IsNumeric(TextB ox1.Text) Then
from = TextBox1.Text
Dim n As Int16
Do
n = from Mod 2
TextBox2.Text = n & TextBox2.Text
from \= 2
Loop Until from = 0
End If
Hope this helps.

In addition to Jay's reply, you can use 'Val' to parse a string
containing a number in hexadecimal format.

Jason,
In addition to trying Convert.ToStrin g as Greg and I suggested.
Consider using <<= or >>= instead of *= & \= by 2.
In VS.NET << is the left shift operator, while >> is the right shift
operator
So: from \= 2
from >>= 1
Are both the same, while the second may be faster, as bit shifting is
normally faster then division.
Hope this helps

Jay/Greg,
Thanks for the feedback. I have been using variations
of the routine I submitted in VB6 and C for a long time.
Your improvements will help the speed and readability
of my code considerably.
The string.convert method has a huge number of
possibilities in my VB.Net code.
Regards,
Jason.

Hi,
I need to convert a Binary value to Decimal. I've been told that the
value is an unsigned one. How can I do this?
I use memcpy into an unsigned char variable, but when I print the
value I got a negative value.
For example if I'm using the xd -c (Unix) on the file, I can see the
value FFFFFFFFFFFFFFA2 which using the memcpy as described above I get
-94.
But the real value that I'd expect to get is a positive one.

Hi...
I would like to take a string like 'supercalifragilisticexpialidocius'
and write it to a file in binary forms -- this way a user cannot read
the string in case they were try to open in something like ascii text
editor. I'd also like to be able to read the binary formed data back
into string format so that it shows the original value. Is there any
way to do this in Python?
Thanks!

Hi everyone...
I have a data with both decimal and Hexadecimal numbers. I am extracting the required data from for analysis with the help of MINITAB 15. The problem is MINITAB 15 is not accepting the Hexdec data, so while extracting itself I need to convert the data from Hex to decimal. For extracting the data I am using Visual Studios "VC++" can anyone help me how to do the conversion.
Thanks in advance
