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?

View 6 RepliesI 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?
View 1 RepliesI'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 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 want to know the code for an average of numbers from 1 to a number entered?

I am trying to use the xml comments suggested (with VB in a ASP.net project in Visual Studio 2008).I want to give examples of how to use a class, for example, so I write [code]This is readable in the code itself, but the resulting help information in the Object Browser is unusable.The summary, parameters and returns stuff is OK,but the example code is all as one block, with a single space instead of the line endings.I know that most XML treats all whitespaces the same (space, line ending, etc.) but since <code> is described as being for multi-line code blocks, I expected it to respect line endings and indentation.Ideally it would colour-code the code as visual studio does, but the least it should do is respect space (similar to the HTML <pre> tag).Otherwise how is it useful for multi-line code blocks?

I was thinking of an efficient way to add quarantining abilities to my antivirus application. I was thinking, which way is better: to copy the file into a specified directory and change its extension to none ("*. "). Either that or maybe I can save the file's binary code in an XML database. Which way s better?However, I have no idea how I will recompile the binary code once the user wants restore the file.
View 2 RepliesCouldn't think of a better title.(Background on the problem/me)Okay, so, first question/post here, so hi. Now that that's done with, the information pertinent to my problem. I'm fairly new to VB (and programming as well, aside from screwing around with C++ and learning assembler(well, attempting is the better word) god knows how many years ago), and have only seriously been programming for about under half a year, and my skill level is about at that stage. Only been using VB.Net, nothing older. Depending on the time of day and if I'm home or at school, I fluxuate between VB express and Vis Studio 08. Umm, this program I'm having trouble with was on a test that I took yesterday (took the problem home with me cause I really wanted to figure out what was wrong with it).
The stipulations of the test were:
No For->Each Loops
No using Built-In Sorting or Searching Functions

I'm running Visual Studio 2010 on a terminal server, and have been, with relatively few problems, for some time. This morning I fired up my PC and over the UK's long weekend, the following issue seems to have developed.I've got a bunch of projects (but not all of my projects, and not all of the projects in a given solution) complaining that a particular file (which does not exist on the computer) cannot be opened, and so those projects will not compile anymore. Here's the error:
Error 31 Unable to open module file'C:Users[username]AppDataLocalTemp2.NETFramework,Version=v4.0.AssemblyAttributes.vb':
System Error &H80070003&
I could simply copy the file into that directory and be done with it, I'm pretty sure that will work,EDIT: Okay, now things have gotten to a whole new level of weird. I've rebooted the server, I get the same error message, only now the file it is asking for exists and can be opened in Visual Studio with no problems. another part of the IDE still insists that it's unable to open the module file.
EDIT 2: Can't delete the file because it claims to be open in another program, but I've logged off and logged on again, and there shouldn't be anything accessing it.
EDIT 3: Because there's a wall of comments below his answer, I'll mention here that Jared's suggestion to delete the SUO file for the solutions having the problem (not files specifically to do with any of the problem projects, strangely) was what solved this, eventually.
