Convert Binary Numbers To Decimals
Jun 13, 2012
I've used .NET for a long time now but I have come across something I haven't had to do before and I'm struggling to work it out. What I need to do is work with binary numbers and convert them to decimals and vice versa but not necessarily using even numbers e.g. I would like to represent a number between 0 and 2047 which can be represented with 11 binary digits. Plus I want to represent a second number between 0 and 500000 which can be represented with 19 binary digits, and a third number, fourth etc. Then I want to string the whole binary results together and split it in to sections of lets say 5 bits each and convert those back to decimal.

If i wanted to know if a whole number is a multiple of 10 or not I know i can do for e.g
If VarWholeNumber MOD 10 = 1 Then
......
Endif
But if i have a whole number with format "0.00" how can i only check if the last 2 digits after the decimal is a mod of 10 regardless of what the whole number sides value is.
So something like
If VarWholeNumber's ".00" MOD 10 = 1 Then
.......
Endif
How could I could this?

I want to know if there is an easy and short way to remove all characters except for numbers and decimals from a string. Either that or have a textbox that will only except numbers and decimals, but not a masked textbox.

Dim y as integer
dim x as double = 125 / 60
y = Convert.ToInt32(x) 'removes decimals
That method works, it removes all the numbers after the decimal.
But, how to check if the double contains a decimal and if it has it, remove all the numbers after it?
I have tested all the possible solutions i can think of, but I always run into a lot of errors

I have some questions regarding vb.net bit shifting. I understand the << >> operators are bit shift operators in vb.net. I have a two byte hex value 0x3ACC, each bit in this two byte represents either a day, month or year. The bit structure of this hex value is yyyy yyym mmmd dddd. I am confused as to how I should bit shift these values so that year, month and day are in their own UINT16 values. Just want to know about shifting numbers and if I need to add any padding to the shift?

I have a hw assignment and it asks this: program Description: Write a program that has four sub procedures that will calculate and print out a table of numbers 0 to 17 in decimal, hex, octal, and binary notation. Statements Required: output, loop control, subprogram
Sample Output: (you will design your own output but 4 adjacent label boxes would be suitable) [Code] What I want to know is how do I display my numbers from 1 to 17 as either Hex, Decimal, Octal or Binary. Also how would I display that on my form?

I'm reading three bytes from a byte array. They are supposed to be the "Binary code of the e-card no". (e-card is a electronic card used for storing different information). Well, it works fine sometimes, and sometimes not.

I need to document binary files containing integer and real numbers. I use BinaryReader, and BinaryWriter classes, with functions like ReadInt16, ReadSingle, or ReadByte. The files should be readable by any other hardware architecture/OS besides x86/Windows.
I need to document the type of default binary encoding, and can't find the MS documentation.The best I found says that it uses UTF8, but as I understand, UTF8 is for text formats, not for binary numbers.
I suposse that the answer I are looking for, is something like "little endian" or "big endian" format.

I'm wanting to make a program that translates binary code into numbers/letters and numbers/letters into binary code. I know the general system of binary code, but I dont know how to translate anything with VB.net. Is there a general command I need to use or can someone link me to a good tutorial about translating?

I have created in Visual Studio 2008 a Form with two buttons, a PictureBox and a TextBox. I've made the first button to load an image from my hard disk and I want to make the second button to convert the image into binary code and show the string in the TextBox. Image format is Jpeg. Here's the code for the first button:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click PictureBox1.Image = Image.FromFile("D:\Pa.Pei\Pa.Pei. - Ergasies\4o Έτος\Ανάλυση Εικόνας\011.jpg")

I 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.

converting an image file into binary text in VB 2010.I am working on a compression program and need to see the actual binary as text. I have code for converting text files to binary and it works fine but, need to attempt files with greater randomness that are typically uncompressable.(JPG's) I understand that the file conversions may be huge. I plan on manipulating the binary in smaller manageable chunks.

How can I convert a subnetmask into binary, so I'll end up with 32 digits? I can convert it into Binary, using Convert.ToString(Long-to-convert, 2). But a subnetmask of 255.255.255.0 returns(it returns it without the spaces though):

I would like to convert an Bitmap image to an icon in VB.NET but I have to use the binary data of each to somehow accomplish that. Doing research on Bitmap I found how the files are structured. I know that bitmaps have the Bitmap Filer header, Bitmap infoheader, and the colorallet. Each of these contain a certain amount of bytes, and I a have to get these from the bitmap file. The icon header and info header are similar to the bitmap. I know that there are libraries in VB.NET that do that easily, butthis is for a project for school and I am not supposed to use that. I just want to ask how
