I have 4 radiobuttons hex dec oct bin all the buttons works perfectly except the Hex.When i calculate or press a number in decimal, and i check the Hex, the number will perfectly change into hexadecimal, but when i try to calculate within Hex, its a calculation in Decimal.So i repeat.. i can calculate in base 8 octal, base 2 decimal, and base 10 decimal, but i cant calculate in base 16... and i think it has something to do with the letter notation...
I need to figure out how to multiply hexadecimal numbers in vb .net 2008.Ex / 7E1 x 2 == FC2I was thinking maybe converting the hex to bytes, multiplying that, then back.

i m trying to write a program that displays in a textbox a table of the binary, octal, and hexadecimal equivalents of the decimal numbers in range 1-222.
I have a Form with 4 Text Boxes, 1 label and one button. What I need to do is: Make all the text boxes and label only except Hexadecimal inputs.when I press Button1
Label1 = TextBox1 AND TextBox2 ^ TextBox3 MOD TextBox4
Once again every all the numbers are in Hexadecimal format.
i want to get the correct value if number is more than 16 digits [code]and i change it to double and the value is "1.11111111111111E+16"the answer i want is "11111111111111111".is it possible to get the proper value?
I'm trying to write a program that allows the user to enter 10 numbers into an input box and then the program will use a function to calculate the average of those numbers. I'm really illiterate when it comes to Visual Basic.
I am creating an application that takes two numbers (lower and upper) and determines the prime numbers
Public Class primeNumber Private Sub calculatePrimesButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculatePrimesButton.Click 'declare variables Dim number As Long [Code] .....
Once I hit the calculate button nothing comes up. I've tried adding the first code inside the function with the remaining code but no result. Now I'm putting the first code in with the calculate prime button. I am guessing there's a sqrt method that needs to be applied but I am not sure if it should be part of the function or the main?
I'm trying to create a program which will calculate the Fibonacci Sequence which calculates the numbers correctly however, there are a few problems.
1. When using a Do While...Loop the program becomes non responsive.
2. Kind of dealing with the program becoming non responsive; I am unable to stop the process by forcing the sub to Exit.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Operation.Text = "Calculating...." EStop = False
I have an assignment that includes some extra credit point by making a calculate button take four numbers, add them together and give a commission. I know what I did works, but I just want to make sure I'm doing it right! Let me know if I did something wrong

The string itself contains things like "random" & random.next(1,3) & "random2" etc. The string registers all of this as a string and doesn't actually calculate random numbers.Is there any way to fix this?
I'm trying to figure out how to calculate the lower 7 bits and 7-13 bits of two hex numbers.
Here is some example c code, just need this in vb.net:
serialBytes[2] = 0x64 & 0x7F; // Second byte holds the lower 7 bits of target. serialBytes[3] = (0x64 >> 7) & 0x7F; // Third data byte holds the bits 7-13 of target
The 0x7F is a constant so the only number that changes based off input is the 0x64.
I am trying to calculate the number of years for my calculate age event handler, however i am apparently missing a method or whatnot because im trying to calculate the age , can anyone suggest help on this. I need to subtract years to get my age but when i try the birthdate.Subtract (currentDate) method i get an error about not able to convert from LONG?
So below is what I have.
Private Sub btnCalculateAge_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculateAge.Click Dim currentDate As Date Dim BirthDate As Date Dim Age As Long
im using vb 2010 and currently working on a program that senses and displays values in hexadecimal, i have already done this part, but now im required to convert the value that is in the textbox, for example 006d to 109.
I'm just wondering how to convert a string from a textbox into hexadecimal. I looked all over the internet and only found ways in c#. Does vb.net have the ability to do such a thing? If it can then I'd like to know how to convert string to hex and hex to string.
I'm writing a small program that will convert a negative number (e.g. -200) to a hexadecimal number (e.g. FF38). And back to a decimal number. FF38 back to -200. (I can only use two bytes when converting back and forth.)
Question: is there a function in VB that will help?
I have question about hexadecimal operator and the question what does this mean:(Hexadecimal, Hexadecimal, Hexadecimal, Hexadecimal) = Hexadecimal What does the , mean and how can I put this operator in VB form .
I am trying to display the register contents in a textbox in hexadecimal. I would like to always display 4 characters. The register is 16 bits wide. I have 4 byte parameter variables (param_a_1 through param_a_4) for containing the incoming register value. Because of the way the packet is communicated into the VB app, I pick out the bytes I want displayed and convert them to a string for displaying. The values I get in are not always converted correctly
Searching this forum and google turn up things which seem too complicated(more then 4 lines of code), but maybe it needs to be that way.I have two text boxes. A 1 byte hexidecimal value would be entered in to each of them (0-FF). How can I add those two values together to come up with an integer?I have tried this several ways. At one point I got it to work but only for numeric characters.
I am currently working on a software that will convert a string to it's hexadecimal equivalent and back. I have created the following code to make the convert the string to hexadecimal, but I cannot figure out how to get it back.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim skill As String skill = RichTextBox1.Text Dim skillfullbyte() As Byte
What's the trailing ampersand on VB hexadecimal numbers for? I've read it forces conversion to an Int32 on the chance VB wants to try and store as an Int16. That makes sense to me. But the part I didn't get from the blurb was to always use the trailing ampersand for bitmasks, flags, enums, etc. Apparantly, it has something to do with overriding VB's fetish for using signed numbers for things internally, which can lead to weird results in comparisons.
So to get easy points, what are the rules for VB.Net hexadecimal numbers, with and without the trailing ampersand? Please include the specific usage in the case of bitmasks/flags and such, and how one would also use it to force signed vs. unsigned.

I have a database that is giving me mac addresses as strings. What I need to do is to convert this string to a decimal value, increase it by 1 and convert it back to it's hexadecimal value. I'm familiar with c# but I have to do this in vbscript.
