Architecture :: Class Design - Application Allows Admins To Add Types Such As Document Types?

Oct 12, 2010

I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.

When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.

C# - Webservice Complex Types And Class Inheritance - Use The Properties Of The Base Class?

Mar 13, 2010

Using the following Webservice definition using aClientArgs as a complex type:

public class Controller : System.Web.Services.WebService {
public void save_client(aClientArgs client)
// Save client data
Then defining aClientArgs as a sub-class:
public class aArgs
public string id = null;
public string name = null;
public class aClientArgs : aArgs
public string address = null;
public string website = null;
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="">
When I'm expecting the following:
<save_client xmlns="">

So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

Architecture :: Method Return Types Object Vs String/bool

May 27, 2010

If I'm returning an object, then it's pretty straight-forward. However, if I'm just trying to return whether or not the method was successful or not, what's the best option? Sure ... bool seems obvious - but what if you need to debug or get some additional details out of the method than just "yes/no"? Well that's where a string becomes more obvious, right? You can leave it empty to say that the method was successful or chock it full of details in the case of an error. But this can make it less intuitive to others who may have to run your functions and it also jumbles up everything you wanted to pass back into one large string.

Crystal Reports :: Storing Multiple Data Types In A Class?

Aug 31, 2010

I need help writing a class that will contain three values per item. I'll be passing parameters to a report: Parameter Name, Data type (int, string, date, etc), and Value. When I pass those values to the report using the class they should be in original form (i.e. an integer should be a numeric, a string should be a string, etc.).

I can do it converting the data's value to strings on one end, and reconverting to the original data type on the other, which seems like a lot of runaround. Is there a simple way? Also, if I'm able to store & retrieve the data in it's native format I don't need the "Data type" stored.

Architecture :: Design A Class For Product Searching?

Oct 21, 2010

I'm refactoring an old website that has product search code littered throught the codebehind. I'm trying to encapsulate the search logic into its own class so I've created a Product class with a Search() method. I would like some suggestions about OO best practices so that the class is reusable and maintainable. The questions I have are:

- Should I make the search() method an instance method or make it static? For now the class is just really there to encapsulate my search logic

- If I make it an instance method should it return a list of products or should it populate a member property that I can access like p.Search(); var x = p.ProductList;

- The search method requires upward of 7 parameters of different types, what's the best way to provide them?
- pass them all i.e. p.Search (param1, param2, ..., param7)
- create a SearchParams structure in the class, populate it and pass that i.e. p.Search(searchParams)
- Instantiate a Product object and set properties on it that are used by the Search method i.e. p.ID = 123; etc.... p.Search();

I've used variations of the above before but would like to know what's the best way.

Architecture :: Design An Application To Fetch Data From Different Application Databases

Nov 10, 2010

I need to develop an application, which will get records (orders) from one application and process them. The updates to this records (order updates) will be sent back to the source application for end customer reference. I'm planning to achieve this data synchronization at the database level using triggers and stored procedures to insert database between the 2 databases.

But, the issue is I have to deploy this application in 3 different customer sites and I have to change the database names (cannot use the same database name) in each deployment manually. Because of this deployment issue, I was thinking of handling this within the application where I can store the db name in the database and then build the query within the application, but I dont want to do it as building queries like that doesnt look very professional.

C# - Define A Variable Of Different Types?

Feb 8, 2011

to define a variable/property of more than one type. Let's say i want a property TextWebControl that is a WebControl and also implements Web.UI.ITextControl(f.e. like a TextBox or Label). But i don't want to enforce that it is a TextBox or Label, but only one that inherits from WebControl and also implements ITextControl so that it also would work with controls added in future releases of .Net-Framework.

.Net-Framework 4.0

Edit: I have retagged the question and added VB.Net because it's my default language. Normally it's no problem for me to understand C# also, but i must admit that it's difficult to translate generic stuff to VB.Net without experiences and it's also better documentated in C# than in VB. So i would appreciate(and aceept) a working example of a generic type of ITextControl/WebControl.

From Marc's answer i understand that i need a generic class. But how do i instantiate it in SomeClass? This won't compile:

Class SomeClass
Public Property info As InfoControl(Of WebControl, ITextControl)
End Class

C# - Formatting Address Of Different Types?

Apr 1, 2010

I have various classes which all contain address details, i.e. AddressLine1, AddressLine2, AddressLine3, Suburb, Town, etc.

On the front end, I need to format the address in a particular way, i.e.

AddressLine1<br />
AddressLine2<br />
Suburb State Postcode

If AddressLine2 does not exist or empty, don't show it. Quite straight-forward. I am trying to determine the best way to show this info. At the moment, the Address property of each class calls a FormatAddress method which writes out the html string. This exists as a method of the class. My opinion is that any formatting should exist from the front-end control i.e. ascx etc. However, if these DetailClasses need to format the same address info, what would be the best option, also making it easier to maintain?

How to write expression to handle both items ?

Copy Object Types In VB.NET?

Jul 29, 2010

I am building an ASP.NET application that needs dynamic tables. That's another issue that I've already posted about (and gotten a pretty good response!). Now, I'm running into another issue - I want to add new rows to my table, but given that I will have 10-12 tables on one page, each containing different objects in their rows (text boxes, check boxes, etc.) I need a way of simply generically adding a new row that has the same objects as the first row in the table. Here's my code:

Private Sub AddTableRow(ByRef originalTable As System.Web.UI.WebControls.Table)
Dim originalRow As System.Web.UI.WebControls.TableRow = originalTable.Rows(1)
Dim insertingRow As New System.Web.UI.WebControls.TableRow
Dim insertingCells(originalRow.Cells.Count) As System.Web.UI.WebControls.TableCell
Dim index As Integer = 0
