Handling Fractions - Set Up A Bit Of Code That Would Convert The Fractions To Decimal?
May 31, 2010As a part time CAD drafter I commonly have to do scale conversions from many different scales.I am writing a scale converter that will allow me to enter the source scale (eg. 1/4" = 1'). Then it will provide an area to enter another number, like 3/4", and then produce that number in inches. In the case of 3/4" it would equal 36" or 3 feet. For now it would be fine if only gave me the answer in inches.How would I handle all the necessary fractions? Would I have to set up a bit of code that would convert the fractions to decimal?

Jul 5, 2009I recently found myself in a thread deling with convertions from decimal number to fractions... Being a bit too brusk and dismissing the idea at first.I have now implemented a structure based on code frm Javelia whithc can be seen in this thread.Solitare also proveided code that I eventually understood and was working.[URL]...it a step longer and developed a structure that can also implement calculating with fractions... My first try is also posted in the tread above...
The implimentation is far from perfect, as it does not deal with POW of fractions.. So if anybody has some ideas on hoe to do this with squer root and all pleas let me know and Ill update the code..

What Is The Best Way To Handle Fractions
Jan 19, 2012In an upcoming project I need to keep track of some fractional data values. Due to industry standards around the products which this data describes, it is important to display the fractional value as a fraction and not as a decimal; yet for purposes of sorting and filtering the data values, the decimal value of the fraction should be known.
The obvious solution since the problem describes data is to store the value as both a string-fraction and as a decimal-value. This works fine, but it does leave a disconnect between the two values, when in fact, they represent the same data.Assuming that this project will also include a strongly typed object model, which will likely drive a EF4 Code-First database, I think that the best solution involves creating a custom fraction type which can encapsulate the string and decimal values.
After thinking on the problem and some experimentation, I've come up with the following structure to meet this need, however, I'm not certain that it is the all-around "best" implemenation.Obviously "best" is a subjective term, but in general the type should be well-rounded for as many uses as possible... idealy as generic as the Decimal type it enhances. Can anyone spot any flaws or drawbacks with this implementation? I'm still not sure about the numerator and denominator fields... whether they should be readonly or priviate or what...
Here is the code:
Imports System.Runtime.Serialization
Imports System.Text.RegularExpressions

DB/Reporting :: Proper Use Of ADO.NET?
Nov 18, 2009Whenever I work with applications involving database I have this habit of declaring a global variable that holds reference to a Connection object and keeps it open throughout the lifetime of the application and closes and disposes it accordingly at program exit.I've been doing this since my VB6 days and still doing it now in dotNET. I've read a lot of articles regarding this practice and most of them states that it has great impact on connection pooling. Does this also mean something when my application connects to a database file (i.e. MS Access, flat text files)? Is it true that the DataAdapter and Command objects open and close the connection?

Proper Two Way Binding?
Mar 21, 2010The problem I am experiencing has to do with using DataGridView.Member to access a BindingList.
My app has a UserControl called MaterialsControl, on it lives a DataGridView name dgvLineItems. Using the designer, I've set the DataSource for dgvLineItems to the MaterialsControl. MaterialsControl also has a "Items" Property. "Items" is a BindingList(Of LineItem). dgvLineItems.Member is set to "Items." The LineItem class implements INotifyPropertyChanged
Presently, when I add anything to Items, the DataGridView does not show any changes.Alternatively, when dgvLineItems.DataSource is set to Items (which to my knowledge can only be done manually), anything added to Items appears in the dgvLineItems.
Just for clarification, the DataGridView I'm using is for output primarily, the user will be able to delete values from the view, but not edit them. Insertion is done through an event handler.

View 2 RepliesProper Way To Use Resources?
Jun 8, 2010I'm using VB.Net 2008 .NET 3.0.I am not sure of the proper,or best, way to use Settings and Resources. For now I use the default project wide My.Settings and My.Resources.I have a class that I would like to reuse in other projects, so adding project wide settings or resources in each project doesn't sound proper, nor does creating constants and variables within the class itself.
I'm guessing there is a way to give a class its own resource file, and maybe even settings file, but I'm not sure how to do it. I tried adding a resource file with the same name (but with .resx extension) and I got a weird error saying I was trying to edit a resource that is apart of another project. I continued, but it didn't seem to be what I wanted and I wasn't sure how to access that new resource.I'm not currently concerned with internationalization, but it wouldn't hurt to understand how that would affect what I'm trying to do.

View 4 RepliesProper Formatting For Datagridview?
May 18, 2010I am fixing up a visual basic program using visual studio 2005, specifically in visual basic. I am currently attempting to format the datagridview used to display data from a database. The values from the database being displayed are a mix of integers (used for displaying information such as number of units sold) and floating point values (used to display revenue, etc). I need to format all the values to display as integers (by simply truncating the decimal places, not rounding) as all (including the values that should already be integers which are appearing with two 0s following the decimal place). I have used the round function as follows round(value, 0, 1) which as I understand should get rid of all decimal places by simply truncating them, however I am still left with two 0s after the decimal place. Next, I went to the designer view and edited the columns property of the datagridview so that they are all set to be numeric with zero decimal places, yet the decimal still remains. I followed that by going back into the code and change any CType() that were decimal to Integer and still no change.
