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")

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.

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

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).

At the end of a calculation Pweight stores a number, I need to format this number so that it only shows to 2 decimal places.. I have tried this:
[Code]...
This actually seems to make it miss calculate, so I've put it back to Pweight.ToString() and left it at that but I get around 12 decimal places.

I have designed a unit converter that converts between different units. The value and unit to be converted from are entered in the first text box, for example "1 km" and the unit to be converted to is entered in the second text box. Then after pressing the calculate button, the new value will be displayed in the second text box as the output. By default the output will be specified to two decimal places. However, if the input has any number of decimal places, for example "1.045 km" the output should be displayed to the same decimal place, in this case 3.Displaying the output to two decimal places was easy enough to figure out, I just used:
FormatNumber(finalValue, 2)
But I'm completely stuck on the other part however and I'm wondering if anyone here has any suggestions. I thought about doing something like this:

I'm having a bit of an issue getting the number formatting of VB .NET 3.5 to work just right for me. I have to convert numbers to scientific notation, with 2 digits for the exponent and 6 digits after the decimal. I've been able to get this for numbers that have enough digits, but for other numbers, it truncates the number to use as few digits as possible. For example, I would like 0 to be converted to 0.000000e00, or 123.4 to be 1.234000e02.

I'm a noob, so please bear with me. I'm working with VB in Visual Studio 2008. I have an application that displays dollar amounts. With the application installed on my desktop all of the dollar values display with 2 decimal places. However, after moving the application to the server and executing from there, trailing zeroes after the decimal point are lost.
For example - 7.00 displays as 7 - 10.60 displays as 10.6 I'm guessing there's an options file somewhere that determines how these numbers are displaying but I have no idea what that file might be.
Can someone tell me how to get both digits following the decimal point to display all of the time?

I'm fairly certain I'm missing the obvious, but I'm trying to force a datagridview cell to format the contents of a cell to two decimal places when the value is changed e.g. the user enters 20 in a cell and it's formatted to 20.00 when the cell is moved away from.

I have some VB .NET software that interfaces to a load of old (but sound) COM objects. The VB provides a GUI for the COM objects, part of which consists of setting various options on the COM objects - several of which relate to string formatting.I have a simple pair of VB .NET functions that convert basic %f, %d, %g formats to/from .NET equivalents using a large select case covering specific common strings, but they don't cover all formats.[code]Before I start diving in and making it more versatile with some parsing, does anyone know of a class (eg VB or C# .NET) that provides a decent ready-made implementation? Or perhaps some regexp wizadry could be used?

I have a DataGridView bound to a DataTable that has 1+16 columns defined as Integer.The default cell style is hexadecimal 2 digits (.Format="X2").When entering in cell editing I would like to provide to the user, the possibility to write the value in decimal or hexdacimal.Hexadecimal could be written like, for example, 0x00, 0X01, x02, XFF
Decimal like 0, 1, 2, 15For this reason in EditingControlShowing I add "0x" to the TextBox value
Private Sub BankGrid_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs)
Dim grid As DataGridView = DirectCast(sender, DataGridView)

I have a VB Application that is loading an Array with Numbers from the Sequel Server that have numbers 315054 no cents and leaving the .00 off even numbers. I need to write out the number to a textfile that has 14 zero's to the left removing the decimal point from the number.
The Number should format and be written out like this:
00000031505400 in the text file.
My coding does this as long as the even number has a decimal point .00 but if the number comes in as 315054 into my array my coding gives an Argument error with the coding below.
SCreditTextBox1 = Microsoft.VisualBasic.Right("00000000000000" & Microsoft.VisualBasic.Left(_sData(Irow, 7), _sData(Irow, 7, ".") - 1) & _
Microsoft.VisualBasic.Right(_sData(Irow, 7), 2), 14)
Is there a way to check for no decimal point and then place the number with no .00 as 00000031505400?
The accounting people are entering the numbers into the server this way incorrectly. The .00 is suppose to be entered with it, but not all even numbers are entered this way without .00, just a few, but I need to check the number to see if there are decimals and without decimals do something. Could my coding be re-written to account for not having the .00 and to format the number correctly to avoid the argument error?
I need for any number to format with:
$3,000.00 would appear in server as 3000 or 3000.00 and should write out like this below: I need to check for decimals and without decimals and writeout the format like this below:
00000000300000.

I'm trying to alter the existing number formatting in my company's application to make it more readable for international users. This is a stock trading application, so most stock prices come in with numbers precise to 2 decimal points, like so-> 17.23 We could also get ticks in that have precision out to 4 decimal points, so a penny stock might be 0.0341. The original string format that we were using for stocks was "#,##0.00##" Which would give us the format we wanted (essentially trimming '0's). The problem here is the ',' and '.' are forced onto the user, where in many other countries the thousands separator is '.' and the decimal point is ','. Boss man doesn't want to use "N4" for all numbers, even though this would resolve the globalization issue. Is it possible to have a globalized custom string format?
Other options besides writing some middle man code to internationalize numbers formatted the original way or another string.format method?

I am trying to convert information stored in a file to a decimal (or ASCII) format, then write the contents of that file to a new file.
What I have is a list of files that are generated from a cash register. The documentation that was provided to me says that this particular file I am trying to work with has a length of 6, a width of 6, and that it's BCD type.
I've done quite a few google searches and can't seem to find a good solution. I know BCD numbers should be stored as 0000 format. But the problem I'm getting is when I read each part of the file (using my sr.read) I'm getting full numbers..and I am expecting the 0000 format. I'll get a 0, 0, 0, and then all of the sudden I"ll get a number that's 65,000..then I'll get a 34...and there doesn't seem to be any
I'm sure I'm doing something incorrect here, my knowledge of reading HEX, BCD, etc. is very minimal. I'm guessing it has to do with using a filestream, so I can use the fs.ReadByte() method..but when I tried that my program was literally chugging along for several minutes with no sign of ending.[code]...
