Visual Studio :: When Change Any Existing Method Or Property In Business Object Or Data Access?
May 11, 2010
I am working on Vs2005 and asp.net 2.0. I have a solution with 4 projects (business object, components, data access, webclient)When I change any existing method or property in Business object or data access, it is not reflecting in the application. I have deleted the existing references to the project and added them after the new build. I always get errors like "method not found or No overload method "It seems like old verion of dll is still there in the reference.

I have a business object that looks like this:
[Code]....
What is the value of SomeId after I create an instance of my object? I was testing it with SomeId == 0 but it wasn't working. Then I tried null which gives me an error.
What is the right way to handle this? Am I to assign an initial value to my objects' properties in the object? If not, how do check if my object has any values assigned to its properties -- in particular, int values?

So, i am running SQL Server 2008 R2 Express and VWD 2010 Express on Windows 7. I am logged in as admin on my machine. I have created a new web app project (VB Linq to SQL) and I have attempted to add an existing .mdf to my project's App_Data folder. I right-click, choose "add existing...", navigate to the .mdf file in the C:Program FilesMicrosoft SQL ServerMSSQL10.SQLEXPRESSMSSQLDATA folder, and then i get an "Access is denied" error box with no further details.

I have a property on my Global.asax.cs class that I need to access from a business class, i.e. using HttpContext.Current. How do I do this? Global.asax.cs (in a web project)
public partial class Global : System.Web.HttpApplication
{
public static ProxyGenerator Generator = new ProxyGenerator();
Business class (in a separate business project)
var generator = ((Sei.Osp.Web.Global)HttpContext.Current.ApplicationInstance)
This obviously doesn't work and I don't want to reference the whole web project in the business project as it will create a circular reference (the business project is already referenced in the web project)
UPDATE:
To clarify - the property I'm creating holds an instance of the Castle Dynamic Proxy Generator class. I've read that you shouldn't just create this all over the place. So I thought I'd create it in my Global.asax.cs and then just use that instance wherever I need to create a proxy class (I'm using it to do AOP) Is there a better way of doing this?

I'm new to ASP so this may seem so simple but I cannot work it out.
I am trying to create a script that changes its output based on a range of values. Here is what I mean:
I have a MSSQL database with an ASP scripted website that reads it and displays the data in a table. One of the columns in the database is a percentage and I want that column in the web page to have a background colour based on the figure outputted.
So each cell may be a different colour. If the number is between 0 and 30 then red background, 31 to 70 orange etc.
At the moment I have the database output script looking like this:
[Code]....
How can I implement what I have outlined above?

Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID
Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.

I have a VS 2008 solution with 16 projects (1 web site and 15 class libraries. The website uses the assemblies). This all worked fine on Win XP pro.
My work PC just got upgraded to Windows vista business and i'm receiving the following error each time i build the project.
Could not load file or assembly 'xxx, Version=1.0.1363.21887, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Access is denied.
I went on and signed all the assemblies and added them to the GAC. But i keep having this error when i build my project. I'm running vs 2008 as administrator.

Again, I am new to the ASP.NET world, and I come from a Windows Forms background. I'm working with an ObjectDataSource that retrieves a collection of business objects. With the collection, I am going to be binding it to a CheckBoxList and other various controls. The business object that I am using is an Employee.
To get all of the employees, I create an ObjectDataSource and set the "Select" method. I then set the DataSourceID of the CheckBoxList to be that of the ObjectDataSource. When I load the page for the first time, I see all of the employees. Now, the user goes through this page and selects all the employees they want to see information about (by checking the box next to the employee name). Finally, the user hits the button called "Display." Upon postback how do I get a list of those employees? I've tried the following solution, but I'm not sure if it's the best practice in obtaining all those employees again. Here's my solution...
In the CheckBoxList, I set the DataTextField to the Employee's name. I also set the CheckBoxList's DataValueField. This property is a little different. I set this to be a UNIQUE IDENTIFIER, which can distinguish this employee from other employees. Now, when the user hits the button "Display" I use my ObjectDataSource again and MANUALLY call ObjectDataSource.Select(). I cast the returned value as a List<Employee>. Finally, I iterate through all list items in the CheckBoxList...
[Code]....
If the item is selected, I parse through my list of employees that was returned from the bjectDataSource.Select(). I use the item.Value and compare it to each employee's "key." If the key is found, I know that the employee is selected. I put this employee in another list called EmployeesSelected.
Finally, I take EmployeesSelected (which is a List) and set my GridView's .DataSource and call .DataBind() on the GridView.
Is this the "best practice" of re-obtaining the Employees that are selected on my page, or am I making this too complicated?

I have a solution that consists of some web projects and websites (seperate projects in one solution) When I run the main project and debug I want to step into a function that resides in another project as a business layer function and then step into another function in DAL project. I set breakpoints in both projects (DAL and BLL) but am not able to step into those functions!!!
What is the problem with vwd express, It should support such vital thing.

A year ago I did some design work for an ASP.NET 3.5 website that uses an SQL Server database hosted by my ISP. This website is only really active around this time of year for an annual photographic competition. Last year, I installed SQL Server 2008 Development Edition together with a trial copy of VS2008 Professional and the trial period lasted long enough for me to do what was needed back then. My intention was to buy VS2008 Pro around now in time for our current competition. In the meantime, I have reverted to
using VWD 2008 Express.
However, that purchase decision has been put on hold while I check out the economic and practical impact of waiting until VS2010 becomes available (in late March?). I'm guessing that it would be much cheaper to wait for VS2010 rather than buy VS2008 and then upgrade. Money is short because we are a non-profit organisation.
The practical issue is that I need access to SSIS Designer to update a DTSX file I created last year and I need that now. March is too late. The SSIS Designer is part of Business Intelligence Development Studio (BIDS) but BIDS is no longer available to me because it appears to have been provided with the trial copy of VS2008 rather than with SQL Server 2008 Development Edition. When I try to run BIDS I am told the evaluation period has ended. Is there is any way for me to gain free access to BIDS 2008 while I wait to buy VS2010?

I have a .NET 2.0 website that was created for us by an outside company.
I don't want to change the current structure, but would like to start adding new items via VS.
What is the best route? creating new items in VS2005 and putting them into the structure, or getting the site uploaded into VS to create new items.

I know you can add an existing item(s), but is there a way to add an Existing folder (and contents) to a project? It sucks without this option. I need to add a folder that has many folders and a lot of content.

I am trying to open an existing asp.net app. on my local machine with VS2008. The app. resides in a folder on the Windows 2003 Server. The app. runs on our intranet. Recently, a change was made to the app. directly by opening one of the files in the solution and adding maybe a couple of lines of c# code and saved back. Of course this would not make a difference as its not been re-compiled.
I copied the whole folder where the app. resides on the server to my desktop and then tried to open the solution with VS2008, it came up with a prompt saying the app was written using a previous version of Visual Studio and needed to be converted to VS2008 format, I followed the intructions, but it failed saying something like "...failed to make a backup etc", it wouldn't open the solution.I have successfully open other apps this way but this one particular one would not just open. All I want to do is to use VS2008 to recompile and publish back to the server. I have tried using VS2005, it just says the app. was created by a newer version of the application...
I think the app was built sometime btw 2004 - 2008. Also, if it is relevant, the folder where the app. resides on the server has a globe icon, don't know if its an IIS thingIs there any other way to compile this .net app. without using VS2008,

I'm working on a site where we want to include a pie chart on a page. Right now I'm working on implementing that through Reporting Services (RDLC file) with an object data source.The SelectMethod of my object data source is a method that returns a list of business objects; lets say a List<Alpha> and Alpha has a sub object Beta with a Name property. In my report definition I have set the Category groups to be: =Fields!Beta.Value.Name this means that Alpha.Beta.Name are my pie slices. I got the following error:
An error has occurred during report processing. The Group expression for the rouping 'chart1_CategoryGroup1' contains an error: Object variable or With block variable not set.I was able to confirm this is because Beta is nullable and was able to fix the issue by updating the object Alpha to return a new Beta() if the Beta property is null. This solution is not ideal though because there are other places in my code where I need Beta to be null if it doesn't have a value yet.Is there a way to update the report definition to accept a null property as valid? Ideally I would like to specify the value as "Not Set" if Beta is null.
