How To Check If A Number Is A Muliple Of
Apr 30, 2010
I can't seem to figure out how to make a function that check if x is a multiple of y. For example, 64 is a multiple of 8.Here's what I have, it's simple but I'm stuck:
Function IsMultiple(ByVal Number As Integer, ByVal Multiple As Integer) As Boolean
If Number / Multiple = 0 Then
IsMultiple = True
End If
End Function
Line2, if the number is a multiple it would return a number without decimal, but I dunno how to check if it is or not.

I have an Article object with the following properties:
Article Name (varchar)
Article Body (varchar)
Article Tags (varchar)
The Article Tags is a space delimited string of text values that a user has tagged the aritlce with. The 3 properties are passed to a stored procedure.
I now want to do the following:
1) Insert the Article Name and Article Body in the dbo.Articles table and return the article id
2) Insert each value of the Article Tags string in the dbo.Tags table as a separate row but first check for duplicates. If duplicate then return the tagid of existing record, if new record then return the new tagid
3) insert the article id and each tagid as a separate row in the dbo.TagMap table
I need to know the best approach to how I would accomplish this, also being conscious that it does not cost too much in performance.

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

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.

Part of my assignment is to check if input to Group Number and Number of Units are correct input by making error handling exceptions...
I have to check the following:
a) group number is neither 501 nor 062
b) number of units are NOT numbers
c) number of units is NOT a positive number
So my first question is, am I checking correctly? 2nd question is, How do I make sure my Exceptions will pertain to their correct respective things (a, b, and c.. above)?

I was trying to get this work, but couldn't find a way to work this out. I'm new to vb.net. In a text box, the user enters a number for example a 9 digit number. I want the user enter to enter a 9 digit number that is starting from 8. if the very first number of that set is not starting with 8 then give a error msg to the user to enter a number starting from 8.

I'm reading data in from a comma-separated text file and storing the data in an array for later use. Some of the values are to remain as strings, and I need to convert some to integers, for which I was trying to use, for example, integer.parse(ar(0)).
My problem is that the string values are randomly distributed through the text file, so I need to be able to test whether the string can be converted at all before doing the conversion.

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()

I need to check a value and make sure that it is not a negative number using a try catch statement I keep getting an error saying that I have to use a method.
Try
TotalCurrentBalance < 0
Catch ex As Exception
End Try
I wouldn't put a if statement would I? I am thinking that would defeat the purpose.

I was wondering what the fastest way is to check for divisibility in VB.NET.I tried the following two functions, but I feel as if there are more efficient techniques.
Function isDivisible(x As Integer, d As Integer) As Boolean
Return Math.floor(x / d) = x / d
End Function
Another one I came up with:
Function isDivisible(x As Integer, d As Integer) As Boolean
Dim v = x / d
Dim w As Integer = v
Return v = w
End Function

I have a listbox, textbox, and a button. every time I push the button, an item from the listbox is put into the textbox. when the button is pushed again, it grabs the next item in order and puts it into the textbox. so on and so on until it gets to the last item. once I get to the last item it keeps repeating the last item over and over again. SO what I was wondering is how do I get a messagebox or some sort of checker to tell me when it has moved the last item from my listbox to the textbox?? PS textbox2.text=0 and every time the button is pushed another number is added to the value of textbox2.text. so basically if I could figure out how to grab the value of lines at any given time in listbox I could call a msgbox up!! here is the code I am currently using[code]...

I'm working on a console application in VB .net that checks a number that the user has inputted, and tells you whether the number is prime.
The number that has to be inputted has to be between 1 and 100. I have all the code so far and at the moment it can check whether the number is or isn't within the boundries.
