# Convert A String Containing A Binary, Octal And Hex Number Into A Decimal String?

Jun 7, 2009

I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:

dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec

I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

## DateTime Binary Coded Decimal Byte() Equivalent Of String Format?

Sep 30, 2010

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.

## Convert Binary String To Integer?

Jul 26, 2009

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)

## Formatting - How To Convert Decimal To String

Apr 14, 2009

I have an app that deals with currency. For display purposes I use the nifty VB FormatCurrency function which will format based on the OS's region setting. So, if in France you might get 123,45 where in the US you would get 123.45. To perform calculation on these amounts I use CDec() to convert to decimal.

My problem is that when I convert the Decimal to a String using toString() it formats according to the currently set region. I need to be able to always convert the decimal into a String representation for the US, i.e. with decimal points. I thought I would be able to do something similar to this:
.toString("#0.00")

## Stuck Trying To Convert A String To Decimal?

Aug 1, 2009

i'm a little stuck with a personal project, i'm interfacing a MiniBee usb output card to my pc and having a few code problems, i am trying to control outputs 1 to 8 which requires a decimal number that relates to the binary pattern of the ouputs if that makes sense i.e

1 = output 1 on
2 = output 2 on
3= output 1 and 2 on
etc etc

So, i figured the easiest way to individually control outputs was to use public boolean vars Out1 to Out8 so i can use those anywhere in the code and use a form timer to trigger the updating of the output

So the bit im stuck on is i've done a test using 8 checkboxes to set Out 1-8 as true/false

## Convert String To Integer With Variable Decimal Sign?

Nov 22, 2011

I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.

At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.

The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).

## Asp.net - Decimal.parse Fails For Currency String Created With String.Format?

I have a field that I display via: String.Format({0:c},amount) This produces the string "\$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "\$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?
