Programmatically Go Through Several .aspx's Business Logic?

Dec 6, 2011

I have several successive web pages going through a checkout process and they each have tons of business logic that time restraints limit me from pulling out and wrapping up elsewhere in the code the way it needs to be. What would be a good method for calling each one of these pages' Submit buttons in order from one page to the next?

The way I was going to do this was to (laugh at me go ahead) make PUBLIC all of the submit buttons' code and just call them. But what I have found is that all of them have, of course, certain calls to controls on their pages where it might make a label visible or change a text property then that will crash the app due to a null reference. I believe it is basically saying if the webpage is not visible then it is not going to let the code start setting certain GUI properties of the controls on the page. It seems like I recall this in VB6, too.

Anyway, what would you do if you were in this situation? I have started down the path of creating a flag that says whether or not I am in expresscheckoutmode and, if so, it just doesn't do the "illegal" things mixed into all of the code like making labels visible and all that. But that also means that I have an IF BLOCK everywhere where the code simply changes a label. It junked up the code bad and I still haven't finished that implementation of it all. I wanted to come here to ask the collective mind what programming principles I can best apply here.

VB Code Behind The Business Logic Layer?

Oct 1, 2010

I also went though the whole "ASP.Net in 24 Hours" book by Scott Mictchell. I followed everything that went on in that book and built the final project successfully. I also used the tutorials here to better understand the whole Membership Provider/User tables setup that was going on in the book. Next, I thought I would learn more about accessing data for ASP.Net since that is what most application do.I went through the first Data Tutorial here. I seemed to understand what was going on just fine.The second Data Tutorial seemed to just show a lot of VB code to build the Business Logic Layer. There was not much explanation about how to do it yourself.I think I can keep going in the tutorials here. I downloaded the code from the second tutorial and went through it.I am guessing that the code in the second tutorial was given just to proceed with the overall project that is being built throughout the tutorial sequence.

Asp.net - Updating ListView From Business Logic Layer Method

Sep 7, 2011

I have a shopping cart ListView control backed by a custom object that has methods for selecting and deleting. In the ListView, one of the columns is an ImageButton that is essentially a delete icon, with the CommandName parameter set to CommandName="Delete".

My issue is related to updating the shopping cart ListView on delete; as the delete method is stored in the custom business entity object, I am having trouble in terms of updating the calculations made inside the cart (we have deleted an item, so I need to recalc shipping, taxes, etc).

Moving From ASP Business Logic Trapped Inside Stored Procedures

Oct 28, 2010

How would you structure a large project with most of the business logic already inside stored procedures?We are moving from classic ASP to ASP.NET (VB) and pretty much all the business logic is inside stored procedures.Getting the logic out of there is pretty much impossible since my boss doesn't want to (too expensive, takes too long, no "real" added value).I was thinking about making a presentation layer made of aspx pages, a business logic / data access layer that would basically get the data and interact with the existing stored procedures and a business entities layer that would be made of classes (for entities and collections) containing the information to interact between those two layers.The reason I wanted to make those layers was to be able to reuse most of the code without duplicating it.

IDE - VB - Business Logic - Unable To Inherit Or Call The Location Collection Class

Feb 17, 2010

my form displays locations and owners for a same product, the forms have a data grid view that actually takes in the details of the location and owner of that particular product. a product can have multiple owners and locations once its manufactured over time, the forms actually display this all i need is some kind of business logic that can actually manage the historical events of the location and the owner that when a user actually goes in and adds a new entry, the end date of the previous owner gets reduced to one less than the start date of the new owner. this in formation is stored in business layers called the owner collection and the location collection, i am not able to actually inherit or call the location or the owner collection class in the classes.

Validate Business Object By Use Of Related Business Objects?

Oct 11, 2010

using an object-binding I have a an object representing "Employee". The employee has an ID-property. The ID of the employee must be unique.

My validation of the entered data is handled in the property set part of the object. In general, I validate criteria belonging to the object to validate only (eg numeric range of the ID, if it's value is not empy, ...). But in this case I need to know all ID's from the other employees. My tried this:

Using Timespan To Calculate Hours, Mins And Secs From Secs?

Apr 27, 2009

23430 seconds = 06:30:30 (hh:mm:ss)52230 seconds = 14:30:30 (hh:mm:ss)The problem occurs when my total seconds goes over 24 hrs. So for example,95430 seconds should equal 26:30:30 (hh:mm:ss) however comes out at 02:30:30.Here is the sample code, note I have tried using TotalHours, TotalMinutes TotalSeconds however this does not give the correct result. I potentially need to be able to calculate upto 1000 hours - e.g 3601839 should equal 1000:30:30 (hh:mm:ss)

As TimeSpan = TimeSpan.FromSeconds(95430)

Which Is Better For Web Business Application

Sep 2, 2009

This is a debate that can never be fulfilled without you. Please come forward and respond.What if we have a client who wants to develop a web enterprise application (based on SAAS architecture) and prefers for C# and not VB.NET based. Argument can be:

1. C# is better suited for developing enterprise application versus VB.NET

2. C# is object oriented versus VB.NET is not

3. Programming in C# is faster than VB.NET

4. Libraries/function blocks in VS.NET is more for C# versus VB.NET

I would request you to help me answer this. I believe this is the type of questions many faces when deciding for which language to go for, both developers and organizations.

Business Layer Vs SQL Server

Jan 24, 2012

I have an application that does complex calculations for members. Each member can have multiple US states linked to their profile. Each state has got different calculations for each course a member completes. As of now I have been performing the calculations in the DB (SQL Server 2008) and then sending data back to app layer where they can see their history and then download a certificate for each course. I have a business logic layer but not a lot happens there. I know this has been asked a lot but where do you think I should perform these calculations: business layer or database?

GUI To Business Object Mapping .Net?

Jun 17, 2009

The issue I'm currently having is mapping multiple GUI fields to object properties (i.e. Presentation layer to Business Logic Layer mapping). To be more specific, this is in VB.Net 2.0 WinForms. The nature of the solution requires us to have 4 columns which exhibit the same type of behavior on our GUI - each column consisting of 11 textboxes (we'll just use this small sample size, as the problem extends beyond 11 textboxes).

What I am currently doing is setting the tag of each textbox in all four columns to a value like so:

Textbox1.tag = "name"
Textbox2.tag = "type"
Textbox3.tag = "speed"

[Code]...

As you can see this can get very bad, rather quickly. Currently we're setting 43 some odd properties that can be mapped to -- thus that select statement is extremely long -- many of which are embedded in multiple methods to try and attempt DRY (I've watered down the code to essentially a conceptual implementation).

Question is: how can I refactor this? I've attempted using a dictionaries/hashes to a certain extent, but it either became overly complex, or just plain didn't make an implementation sense as it convoluted the problem even more.

.net - Methods For Checking Business Rules?

I was having a discussion with a colleague about a method used to check business rules. In general there are two conditions:

"If one fails the whole thing fails"

Example 1: "If one fails the whole thing fails"I have used the following technique for condition 1 in several cases. Essentially if one of those conditions is false then the whole thing fails

Big Business In Shirts, Especially For Groups And Teams?

May 20, 2011

does a big business in shirts, especially for groups and teams. They need a project that will calculate the price for individual orders, as well as a summary for all orders.The store employee will enter the orders in an order form that has text boxes for customer name and order number. To specify the shirts, use a text box for the quantity, radio buttons to select the size (small, medium, large, extra large, and XXL), and check boxes to specify a monogram and/or a pocket. Display the shirt price for the current order and the order total in labels.

Include buttons to add a shirt to an order, clear the current item, complete the order, and display the summary of all orders. Do not allow the summary to display if the current order is not complete. Also, disable the text boxes for customer name and order number after an order is started; enable them again when the user clicks on the button to begin a new order. Confirm the operation before clearing the current order.

When the user adds shirts to an order, validate the quantity, which must be greater than zero. If the entry does not pass the validation, do not perform any calculation but display a message box and allow the user to correct the value. Determine the price of the shirts from the radio buttons and check boxes for the monogram and pockets. Multiply the quantity by the price to determine the extended price, and add to the order total and summary total

The assignment also requires a pop up message "Daily Summary" with total shirts sold, total sales, and average sale per customer.So far I have this as my code but I am not sure what needs to change in order to display the correct total shirts- mine only displays the last accepted shirt order.

Building A Timeline Using Business Days?

I am writing a program that takes a shipdate and generates a timeline of deadlines for a manufacturing job by working backwards from the shipdate. I hav no problem handling weekends. However, some holidays are giving me problems. For holidays that don't have a set date (Thanksgiving, Labor Day, Memorial Day...) what is the best way to determine the date they fall on? Most of the examples I have seen use an array of dates (either from a file or hard coded) for these holidays. Is there a way to do this tha won't require someon to generate a list every year for these holidays?
