Dim fault As Double
Dim ng As Integer
Dim input As Integer
[code]....
Halo, may i ask how can i save my answer fault into database after i done division. I am taking the data from textbox(input data) and done the back coding division.
Basically, I want to divide two numbers together and they should be 2 random numbers from 1-12 (I have done that part) but, the answer should be a whole number (i.e. Integer, so no decimal points etc) So, I did the following:
' Initialize the random-number generator.
Randomize()
' Generate random value between 1 and 12.
Dim value5 As Integer = CInt(Int((12 * Rnd()) + 1))
[code]....
but the problem here is that the program crashes after only a few clicks on the button. So I guess the question is: How can I make the program generate two numbers (from 1-12) that when divided become a whole number?(Is there any code that may tell the random generator that I want the numbers to be even?-so all even numbers from 1-12?)
I am quite sure I am gonna feel real dumb when I found where I am screwing up but I am ALMOST done with a fraction calculator (part of a complete algebraic calculator I am making) and am stuck when trying to reduce my fraction because when I hit the reduce button, it only divides the answer by the first number in my listbox instead of all of the numbers.[code]...

consider the following code and comments:
Console.WriteLine(1 / 0); // will not compile, error: Division by constant zero
int i = 0;
Console.WriteLine(1 / i); // compiles, runs, throws: DivideByZeroException[code].....
This test seems to corroborate the idea and a literal double of 0.0 is actually a very, very tiny fraction which will result in Infinity...
Is there a function in VB.net that allows me to divide a really long String into a specific number of characters? [code] The length of this string is 18 and I'd like to group it by 3, so each group would contain 6 characters. Is there an easier way of doing this? Is there a predefined function in VB.net? I'm already thinking of doing it manually, like converting the string into characters and storing them inside arrays.

i have two textboxes where a numeric value will get entered into both, these values will then be taken and the first value divided by the second value. The problem i am having is that if for example the first value is 11 and the second value is 10, when i divide 11 by 10 the result is 1. I have tried setting the output format to have 2 decimal places but it still displays 1 instead of 1.1. [Code]

I'm not getting a remainder like I would have hoped. I'm new and I'm sorry for the lack of intelligence on the subject. To my understanding the Val( function will convert the string to a number, but when I divide it gives me a single number instead of an integer.
Let say I had a project contains 10 forms and 10 reports and typed dataset (xsd)I am trying to divide my project forms into dlls, so when the client had a problem or asks for modification in single forms, I had to build the project all over again and the exe size will be large.
in my current project, the exe size is 4.8 MB, and I am working with customers by internet and remoting, so every time I make small changes (change the back color of textbox in one form) I had to rebuild and send the whole 4.8 MB to the customer. And not forgetting the increasing size of the exe with time.I know that converting my project to class library and built it will convert it to dll, so I had to create a second project to manage it.
1 - Can I convert 3 or 4 forms / 10 forms total in my current windows application project to dll?
2- What is the best recommended method to divide the project into smaller entity.

2. Second of all, where do I save my database in the project? I want it to be included in like project folders...kind of like the App_Data folder in ASP.Net.
3. I'm recieving an error whenever I try to populate more than 1 DataGridView upon form load for some reason...I've tried 5 different ways of writing the code, and I get the same error...there's no error description, so does anyone know what the issue is? Here's the error:
I have a combo box in my visual basic program and would like it to display text when the database has numbers.
For example, the database has values 1,2,3,4 and I would like the combo box to display "Lifo", "Fifo", Weighted Average" and "Specific Identification".
i have wrote a loop to search for duplicate numbers within a column in a database which i have got fine but when i find a duplicate i would like to get the all of the row so if 33 was a duplicate i would like to get the following row.

I have tried to do this buy use something i saw on msnd's website:
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like '33%'")
However if i change the line to notice the i beside the like
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like 'i%'")
but i get Index was outside the bounds of the array. Ok i know that means that there is nothing in my array. What i would like is to find the duplicate row associated i. you will probably understand me better when you see the code.
