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).

Convert The Decimal To An Integer And Then Use A While Loop For Every Text Box?

Jun 21, 2010

I am new to vb and need some help with this change program. The idea is that we are given a certain amoun of change and then telling how many dollars, quarters, dimes, nickles and pennies. I thought I would convert the decimal to an integer and then use a while loop for every text box, i.e. dollars, quarters, dimes, etc.., to show how many of each, but the while loop is confusing for me in vb, but to tell you the truth I don't know if I am on the right track,

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.

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

How To Convert A String Value To A Integer Value

Feb 2, 2010

I am working on a form of copy protection for some software i am developing. In order to generate a unique license for a machine i am aquiring information about the hardware the software is running on. For this task i aquire the 'BIOS version' of the machine using the Win32 libaries. As the BIOS version format can vary from machine to machine i need to be able to convert a string value to a integer so i can perform a mathmatical calculation on it.

A typical BIOS version output may look like 'GBT42302e31' for eg once all the spaces and characters are removed. However this output can change dramatically between motherboard manufacturers.How do i convert the value 'GBT42302e31' to a integer like '5356243' for eg so i can then perform a calculation or hexidecimal conversion on it?.

I have tried the following and they all fail with numerous conversion errors:Cint Convert.ToInt64()
