Document Binary Files Containing Integer And Real Numbers?
Jan 4, 2010
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 have written a VB (6.0) progam that pulls data from a Comm Port. I get two bytes back everytime I real the data (i.e. FF E1).Does anyone know how to represent this as a Real number (or floating point)?

I need to generate 'real' random numbers from 0 to 500 (e.g. 247.214, 477.125, 1.247, 54.078, 147.001 ......etc). I am using this method:
Dim Myrand As New Random
Dim Res As Double
For i = 1 To 10
Res = Math.Round(Myrand.NextDouble, 3)
Next
This method gives numbers between 0 and 1. if I use: Res = Myrand.Next(0,500), then this gives Integer numbers.
The questions is: Is this possible with (Dim Myrand As New Random) or I have to try another way (e.g. Rnd() ) for doing this?

I've already wrote a simple program for connecting to a serial port that can send data to the microcontroller, do some basic arithmatic and transmit it back to my Form. This was just to see if I could set up the conection.I have a PIC Microcontroller giving an 8-bit number thats is taken from an external sensor device.What I want to do now is to present this data from the microcontroller in a textbox as a number either in real time (as the sensor output changes) or if not possible, on request (using a button).

<edit> Now showing the difference as a DECIMAL. Result looks like zero every time. </edit>Disclaimer: This code is provided "as-is" and should be treated as Freeware.( However any donations would be welcome as I have a "so-so" part-time job ).Please note all real numbers to be used should be in this format
"0.000000000000"Do not use numbers in string format in scientific notation like "1.2345E -06"I was feeling bored and decided to add to the code from JohnWein in this thread where I have used a routine that will multiply the contents of two long strings together.>>[url]I have now added a bit of code so you can multiply two really long numbers with or without a decimal point as a full-stop ( period or dot, call it what you like ).

I worked around to modifying regular expression below but i could't get what I need. I google it, many things found but not for what i want. Dim valid AS Boolean = Regex.IsMatch(TextBox1.Text, "^(,?d+){0,20}$")Allow numbers exactly like 32,1,6,32,12,21,21,54,675,8,4,3,2,9,0,21,21,21,43,744 in TextBox1. Perfect.

I have a string I want to parse. I could write the code to do so, but I figured that VS.NET has a parser that should do this for me.however, I can't find it. All the searches I do return info on how to parse numeric values in string form into real numbers. It would be nice if the MSDN search had some ways to allow users to enter more details than just search text and 3 ways to filter out irrelevant stuff. In any case, I also tried things like string.parse (nope - although I kinda figured this would be it.) I also looked at Enum.parse, but the code indicates that it works with arrasy of items, not strings.

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.

I am looking to convert an integer into a boolean array where each item in the array corresponds to a bit in the binary representation of the integer.
MyInteger = 3 '011 in binary
to
MyArray(2) = False
MyArray(1) = True
MyArray(0) = True
Also is there anyway to assign a value to an Integer in binary or hex (like MyInteger = 1010b or MyInteger = A7h)?

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'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.

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'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 was working on editing a code for a simple text program, but when running the program for multiple lines, the text being read gets too long or too many lines, the computer slows down alot and almost stops functioning. I am using standard integers like document.lines.length or listbox.lines.count. I think these are standard integers and I need to know how to enable them as Long of Float Integers.
I'm assuming I just change
Dim X as integer to
Dim X as long
or Dim X as int16
But I'm not sure as everytime I change something I get cannot convert to double. The code I'm interested in changing is ...
For i As Int16 = 0 To ListBox1.Items.Count - 2
The list box will only get to about 3000 items or so.
and
For iPos = 1 To xy
If Mid(sString, iPos, Len(Text1)) = Text1 Or Mid(sString, iPos, Len(Text2)) = Text2 Then
JJ = TextBox1.GetLineFromCharIndex(iPos)
This read box will read documents above 32,000 lines, which is the reason for not wanting to use Integer.

how to use a Dim numbers() As Integer thats bout it here is my problem that iam facing :Use a one-dimensional array to solve the following problem: Read in 20 numbers, each of which is between 10 and 100, inclusive. As Each number is read, print it only if it is not a duplicate of a number already read. provide the "worst case" (in which all 20 numbers are different). use the smallest possible array to solve this problem.

I've used a numericupdown to select a number and then save it to a .dat file
When i try to display the integer in a listbox, it appears as a random sequence of numbers.
for example, if i input 200 into the numbericupdown, when displayed in the listbox, it is shown as 538976366
Is it an error with the properties with either the numericupdown or the listbox? or do you need to see my code?
let me know if you need any more information or code

I used backgroundworker to receive file segments from a server, it taking the segments and save them directly to a binary file. the problem is,I using a global variable to store the "FreeFile()" number.when "backgroundworker" receive "START" it do F = FreeFile()
when it receive "Segment", it should append to that file, but the problem is ... backgroundworker no more recognize the file (which its identifier saved in global variable F) and telling "Bad File"?!
whats the soultion?I think about opening the file and close it each time (not leave the connection to the file available). But I didn't figure out how to append to Binary files, It always replace their contents. and If I use "Append" option it corrupt the file!

For some reason the last PDF file to be written to the "final document" is the only PDF File that is visible when the "final document" is open. However, all of the bytes are accounted for in the file size...so for example: file1 = 60 bytes and file2 = 49 bytes. The final document has 109 bytes but only contains file2 when viewed in the pdf viewer.
