Converting From Binary To Decimal System
Apr 8, 2012
I was given a school project in which I have to make a program that converts numbers between binary,decimal,octal and hexadecimal systems. I have figured out how to make a function to convert binary number to decimal number [code]With this code,a user can enter a number that isn't binary,and program will calculate it. How can I make that program doesn't calculate those numbers or doesn't accept anything else than 0 or 1? This is needed for other cases like octal and hexadecimal system.

I write a program to convert Decimal numbers to Binary numbers. It is working well. But I want to control the bits. i.e - We can write 31 as a) 11111 or b) 011111. When I run my program it displays 11111. I want to take input bit from a text box and display it like 0011111 or 011111 or what ever bit I input. How can I do that ?
Private Sub DecToBin()
Dim i As Integer = txtDec.Text
Dim binary As String = Convert.ToString(i, 2)
txtBin.Text = binary
End Sub

I have a decimal I want to be able to display as a binary or a hex. I keep seeing code that says Convert.ToString(decimal, 2) to display as binary string, but in 3.5 that is invalid.
Is there no built in formating for binary in 3.5?

I'm doing a uni assignment regarding changing decimals to binary. However this assingment seems to be different to most of its kind from what I can see.Our assignment asks us to have a text box in which we'll enter the decimal, then we'll use a menuscript to and highlight the button 'dec-to-bin' which will then change the colour of 8 image boxes (located in a row above the text box) from black to red based on whether the binary is '1' (Red) or '0' (Black) for that bit.I've struggling to find a starting point as I need to ensure I link the text boxes to the outcome of the decimal and binary but not sure how.

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?

What I'm trying to do is store a query string in a table cell. So I figured the best way would be to convert the query string to some binary format for storing and then when I pull it out of the database I would convert it back to a string of text.

Is there a way to convert byte values to binary so i can read the values from the bits themselves? I have some byte whose values are 00 09 and I'd like to convert the values to bits to be like this : 0000 0000 0000 1001. Then I'd like to read the value of first 2 bits and the remaining 14 bits separately.

I realize the code listed below, whose serial port using string formatting which I inherited is complicated. It formats a Date obtained from a DatePicker control into a "yyyy-MM-dd HH:mm:ss" string format to send to a hardware device to be stored via Serial Port retrieves the date from the device and displays to user What I'm trying to do is port the code for use in a Socket rather than Serial Port which wants a Byte Arrray of the same Date Time string variable. I can't figure out how to encode and convert to Bytes the string value used in the Serial Port version. The evolution of the process is listed from top to bottom.

First: Ok so I'm trying to do a project in my beginning VB .Net class. We are supposed to be taking information from 5 different sections of a form and store them into an array and then call upon them later. We have Name, Address, City,State, and Zip. How would I go about saving the information into an array and then calling upon it later through File IO?
