Check If A .NET Decimal Value Is A Whole Number?

Aug 20, 2010

I have class representing a unit of measure with a Decimal as the numeric. Just to simplify things for this example, let's say I'm representing centimeters. I'd like to implement a ToString() method for this class. The thing is, if the numeric value is a whole number I'd like to just display the decimal as an integer. Otherwise, I'd like to keep it as a decimal. So, for example, 10.5D centimeters would display as "10.5cm", but 7.0D centimeters should display as "7cm". I'd like this to be fast and simple to read. I have a working solution, but it seems like there should be a better way.Here's a contrived example showing my first crack at it:

Public Property Units As String = "cm"
Public Property NumericValue As Decimal = 10.5D
Public Overrides Function ToString()

Filter A Dataset Using A Number Different Inputs, Selected By A Number Of Check Boxes?

Mar 3, 2010

I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

ATM System - Check Card Number Matches Up To The Users PIN Number

Mar 13, 2009

I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.

Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.

Changing A Decimal Into A Whole Number?

Mar 31, 2011

I am attempting to take the decimal places of a given input, round it so there are only two decimal places, then change it to a whole number. So far I have been able to remove the integer part of the number, leaving only the decimal, but the other procedures are eluding me. Here's what I have so far: (VB 2008)

Private Function DecimalNumber(ByVal number As Double) As Double
Dim Input As Double
Dim SubtractNumber As Decimal

[Code]....

That code returns the decimal part of the input just fine, and I thought maybe multiplying it by 10 would work....but obviously you run into problems when there is more than one decimal place.
