I'm supposed to convert the string in one textbox to binary, and display it as binary, in another textbox. I can make this part work, but when I want to convert it from binary and back to text, it all goes bananas.Here's the code I'm using for the conversion:
Private Sub Button1_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs

I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.
Id like to create a simple program consisting two textboxes and a button, "whats the point i hear you ask?" simple, id like to be able to enter in a string into the first textbox, press the button and then have it converted into binary and displayed into the second textbox.
View 1 RepliesI got to a snag recently in the program. I know exactly what is going wrong, and I know exactly what will fix it. However, I do not know how to code what I need.
Code:
'a function to determine whether the pokemon is shiny
Function SHINY(ByVal data() As Byte, ByVal IDnumber As Integer, ByVal SIDnumber As Integer)
[Code].....
So as you can see, I need to convert a binary string into an integer so it will work properly. Everything else is fine, I've tested it out a lot and done a lot of debugging, even manually, and I'm sure everything will work. All I need is the code to convert it.
Is there an easy way to do this in .NET.I see the Convert.ToXXXX, but no Convert.ToBinaryString.

I'm trying to convert an integer (0 to 255) into a 2-value hex string. For instance, if the integer was 255, the hex string would be "ff", if the integer was 15, the hex string would be "0f". The issue I'm having is trying to keep the leading 0. I've been able to overcome this by using an if statement to determine if the length is less than 2, in which I would concatenate a 0, but this is pretty inefficient I think. Here's my
Dim get_integer as Integer = TextBox1.Text Dim hex_value As String = Convert.ToString(get_integer, 16)
If hex_value.Length < 2 Then
hex_value = String.Concat(0, hex_value)
End If
how to improve this? I really would like to get away from using the if statement.
