Create A New Class That Inherits From The Base Form Class And Define A New() Method With Parameters?
Oct 1, 2008I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

View 1 RepliesAsp.net - Create A GridView From A Class?
Feb 28, 2012I have recently been working with creating a GridView from codebehind to make it more flexible so that I can eventually have it created based on user specifications.Now I'm exploring classes, and I thought it would be cool to create a GridView class so that whenever I need to make a GridView I can just pass the class my specifications instead of having the same code re-written on each page's codebehind.Here's how I'm currently making my GridView with codebehind. Any idea how I can change this to create the GridView with a class?
.aspx page:
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False"
EmptyDataText="There are no data records to display." AllowPaging="True"
CssClass="GridViewStyle" GridLines="None" Width="100%">

Feb 24, 2010I am working on an ASP.Net 3.5 solution that I did not originally build. I added a class file named Incident.vb to the App_Code folder like I always do.But in my code behind of a web page, I usually create an instance of a class like:

But after I type "New", normally I would see my class file he intellisense but I do not. So it does not seem to be able to find Incident.vb. I have not seen this behavior before. Trust me, my class is correct. I have created many class files like this.[code]...

Sep 12, 2009I am trying to create a Class that is COM accessible.The problem I am having is that I cannot have any arguments in the class constructor Sub New.If I do than I get the error:"MSB3214 does not contain any types that can be registered for COM Interop"I can however afterwards use regasm ComDotNet.dll /tlb to create the tlb file.
However when I try to use the class in VB (after adding the reference) withDim test As ComDotNet.HelloDotNetSet test = New ComDotNet.HelloDotNet("Hello")I get an error.
If I remove the argument from Sub New() everything works fine.
Here is the code:

View 3 RepliesCreate A Project That Contains A Pet Class?
Jun 21, 2010Create a project that contains a Pet class. Each object will contain pet name, animal type, breed and color. The form should contain text boxes to enter the information for the pets. A button or menu item should display the pet information on a separate form. Hint: Use a ReadOnly property on the input form to pass the object to the second form.
What I have done so far is create a new class with the name Pet and have instantiated each object with readonly property. I have also created another form where the information entered by the user will be displayed. Guess I kinda need to know what would be the next step? And I want to ensure what I have done so far is correct.

Create Array With In A Class?
Aug 12, 2009I'm writing a ray tracing program that uses snell's law to trace rays through a system of lenses to examine abberations in a given design.I have a class called lens, which holds variables for example, name of the lens, description, number of elements.I want to be able to have a sub class or array within lens (or some other way to manage this data).I wont know what number of elements is until run time.
So I would need to define the array at run time.Part of the idea of my program is randomly generate lens elements within given rules (as in a massive lot), keep the top designs and continually refine them by making billions of micro adjustments to the variables that define the lens etc, which I can pick up later on as it'll save the database/variables.For example, say Lens(63).NumberOfElements = 6.
I want to be able to access Lens(63).Element(3).Radius1 Etc, there will be a bunch of variables under Element, such as Radius1, Radius2, refractive index, horizontal diameter, vertical diameter, and spacing between the next element if it isnt the first.
And Lens(70) may only have 4 elements etc. How can I define a different array size like that in the class under different parent array indexes at run time?

How To Create A Dataset-like Class
May 18, 2011I've been struggling with this for a while, so I finally decided to ask the question rather than try to figure it out myself.Generally, what I want is a more robust Dataset. I have to do a large quantity of hiarchical calculations, doing a wide variety of calculations.I used datasets for similar situations in the past, but there are some restrictions with datasets that I need to have, such as:Datasets are restrictive in their calculation methods, such as having no method for doing powers calculationsDatacolumns are restrictive in the types they can be, at least in the designer. I need members of this class to be of custom types.
I like the way expressions in datacolumns will calculate only when the dependent columns change. If I build a custom class that recalculates every time the value is accessed, it takes an unacceptable amount of time to recalculate all of the fields. I'd likethe class to only recalculate the value of the field when it needs to.
