Decimal To Binary Conversion?
Mar 6, 2010
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 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'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.

I am writing lots of numbers to a binary file, using the "My.Computer.FileSystem.WriteAllBytes" method. I'm struggling with reading the numbers back in....
Code:
Private Sub trial()
Dim vals1() As Byte
Dim vals2() As Byte
[Code].....
How do I know where one ends and the next begins? This is especially important because the length of vals could be something other than 8....

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 have an image stored in the database as varbinary(max) When it's read out into a datatable, it's only being displayed as System.Byte[]. I've tried every trick in the book to get the binary in string format so I can write it back to the varbinary column in another database.

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 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.

So, yes, I've tried with these three formats, and the problem remains the same:I have a string, "s"For Each s As String In stringarray and this array is recieving data from a streamreader that is reading a csv file. The data I'm having dificulty reading are these very specific numbers(yes, only these numbers, because phone numbers get home safe and sound).The numbers I'm talking about are usually decimal.ValueList.Add(Convert.ToDecimal(s))
Now, when I convert them like that, they always bring a "D" alongside with them. I've personally checked the string multiple times, and it just has a "1", and somehow, my list recieves "1D" as a number, same thing happens with decimal numbers(0.29D for example). I've tried with Doubles and Integers, the result is the same.

I am writing a program that asks the user for their name and the number of pieces they completed. The employees are paid more depending on the amount of pieces they have completed(i.e. <200 = .50 per piece, 200 to 399 = .55 per piece, etc.). I have to display the amount earned when the user enters the info and hits the calculate button. I have to use Select Case.
I was thinking this would be an easy program but I keep getting an error for each Case saying "Option Strict On disallows implicit conversions from 'Double' to 'Decimal'. I don't understand why it thinks it is a double. It says I can correct this problem by adding "Cdec" before each equation(i.e.

I have a problem converting decimal number from label's string to decimal... (for example Label1.Text = "0.5"). It works fine on Vista, where I made my application, but it doesn't work on XP and 7. It converts from 0.5 to 5
VB
Dim dec1 As Decimal
dec1 = CDec(word1) * CDec(u1.Text)
'word1' is an integer. For example, if word1 is 100, on XP I get result 500.

Please excuse the newbie question as I started learning VB last week . I wrote the following test code below to add two values entered in two textboxes and display it in another textbox. However I keep getting the exception. "Conversion from string "" to type 'Decimal' is not valid" with the code below and I cannot figure out why . I thought converting using 'CDec' resolves this issue ?

I have a xml node, which can be shown in immediate window as
?Me.SelectSingleNode("./FloatAmount").InnerText

However, I want to return a decimal value.
?cdec(Me.SelectSingleNode("./FloatAmount").InnerText)
Run-time exception thrown : System.InvalidCastException - Conversion from string "100.00" to type 'Decimal' is not valid.
