I'm using the following code to retrieve a value from a SqlDataSource:
[Code]....
The code works fine as long as the variable has a value. But if it's null, then I get errors. How can I test if the value is null?
I've created a WCF Service that Performs Insert User, What it does is, it'l get user name, age,gender,address,phone no and inserts these values into SQL database.
Problem is :
These things are working fine, if i give all the values in the WCF Test Client, It's Not working when i din't enter value for Address and click "Invoke" Button, It's throwing an Exception Procedure or Function "Insert_User" Expects
ADDRESS' Which was not supplied. I've created the SQL table Which allow Null Values for Address.
I've did the same Operaion in WebService also, there it's working fine, if i din't enter any value for tha Allow Null Colums, it's accepting the Null value and inserting into Database.
Why this Problem comes in WCF Test client, Guide me to Get rid of this Problem.

View 1 Repliesvar query = from emp in dbEmp.Employees join dept in dbEmp.Departments on emp.DeptID equals dept.DeptID where dept.DepartmentName.Contains(this.TextBox1.Text) select new { EmpID = emp.EmpID, EmpName = emp.EmpName, Age = emp.Age, Address = emp.Address, DeptName
= dept.DepartmentName };
if (query==null) Label1.Text = "no results match your search";
GridView1.DataSource = query; GridView1.DataBind();
Everything works in the right way, but the label doesn't show the message when query result returns null. The label can show without condition(querry==null). So how to test if a var query result returns nothing?
i have to do some message exchange with a 3rd party (in a website).When the client posts a page, i start the message exchange. When that doesn't succeed for some reason, i report this to the client by rendering the page with a message.On the background, in a separate thread, i start a process to send abort messages to the 3rd party. I can't do this while the user is waiting for the page to come back, because it might take a few minutes.But in a test project, the test ends when the message to the 3rd party is sent, and after the new thread is started. But it seems that the new thread also ends, when the test is done.
Is that normal behaviour?I do start the thread in a new class with a reference to 2 objects from the class which tries to send the message in the first place, may that be a problem?EDIT: it keeps running when the whole process is started in IIS

View 2 Repliesi have datagrid , data coming from database but data in database as formated , i want to show data wihotu format
below example:
<B> test </B> data base has this type data
but in grid i want to show test not with format,
i am getting same data from database.
I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.
I have 2 table Table A, Table B.
Table A - Parent Table
ID - Uniqueidentifier not null(PK)
Table B -Child Table
ID - uniqueidentifier null(FK, TableA)
I have a stored procedure to insert data into Table B, but when I tried to insert a null value into column ID of table B, this error came up:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
The statement has been terminated.
The insert statement in asp.net is like so:
sqlcommand.parameter.add(New Sqlparameter("ID", Nothing))
I am guessing adding nothing to the null value column is the problem, but i don't know how to fix it... The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
I have a problem with a SessionVariable. I will explain what is happening:
1. From the default.aspx I send Session["LoginByAdmin"] = "Dummy"; and then redirect to this page where I have the code below. So the Page_Load sees that this Session["LoginByAdmin"] != null and enter this page. This works fine !
2. In the Page_Load, I later fill a ListBox1 with foldernames.
3. With Button1_Click1, I will now delete the choosen Folder in the ListBox1 wich works fine the first time and the ListBox updates the new existing folders in the ListBox. (I have wrapped this inside an updatepanel)
The problems comes now when I try to delete a choosen folder in the ListBox1 the second time in a row. When I select a Folder in the ListBox1 and now Press Button1, I will be redirected to "Default.aspx". This meens that this code is running: (That meens that Session["LoginByAdmin"] == null and I have not set this to null anywhere. This is my big question how this variable can be = null here?
if (Session["LoginByAdmin"] == null)
Response.Redirect("Default.aspx");
break;

I am trying to run WaitN test using NUnit. The test is taken from the book Pro ASP.NET MVC 2 Frameworkby Steven Sanderson and it's located on page 73-74.The test is just testing a default MVC 2 application and it looks like this:
[Code]....
I can run the test in the NUnit GUI, but it fails, I get this error message:IntegrationTestingExample.WaitNTests.UserAccountTests.DisplaysUserNameInPageHeader:System.Threading.ThreadStateException : The CurrentThread needs to have it's ApartmentState set to ApartmentState.STA to be able to automate Internet Explorer.This is the stack trace from the NUnit GUI:

WHAT SHALL I DO TO MAKE THE WAITN TEST PASS? AM I DO SOMETHING WRONG? AM I USING THE RIGHT TOOL TO RUN WAITN TESTS?
My question so general, but I think the answer will be specific.
All I want to know is:
Is there a way or steps or mechanism to test the application (web application) in a professional way?
Many times when I finish developing and try my application, testing it with dummy data several times, and when I think every thing is okay and I think I have covered all possible scenarios, I find I forgot important issues, or others tell me they found problems in my application.
How do I overcome this problem, and save my time?

View 2 RepliesI'm trying to unit test the MembershipProvider, however I cant figure out how or whether there is any need for unit testing of it...
My business layer:
public interface IAccountService
{
MembershipCreateStatus CreateUser(string userName, string password, string email);
}
public class AccountService : IAccountService
{
private readonly MembershipProvider provider;
public AccountService() : this(null) { }
public AccountService(MembershipProvider providera)
{
this.provider = providera ?? Membership.Provider;
}
public MembershipCreateStatus CreateUser(string userName, string password, string email)
{
if (String.IsNullOrEmpty(userName)) throw new ArgumentException("Value cannot be null or empty.", userName);
if (String.IsNullOrEmpty(password)) throw new ArgumentException("Value cannot be null or empty.", password);
if (String.IsNullOrEmpty(email)) throw new ArgumentException("Value cannot be null or empty.", email);
MembershipCreateStatus status;
provider.CreateUser(userName, password, email, null, null, true, null, out status);
return status;
}
}
The only examples I've found so far requires a "MockMembershipProvider" with a local database setup... seems quite odd to me.
I want to test that when my form data is posted back to my controllers that the data annotations and the model binding is going to do its job and give the correct model state. After googling for a while I can't find a really good tutorial or article that shows how to do this.
Can anyone point me in the right direction? What is the best practice in this area? I have read that I may need to use moq and MVCContrib but I have not read a tutorial that makes me shout, "Yes, this is the right way to do it!"
