The connection string in the global.asax is:

Application("DBConnect") = "Server=localhost;uid=xxxxx;pwd=xxxxx;database=xxxxx"

***************************************************************
The error occurs when I run this application in backup server. It works well in the previous webserver. I think the error is in connection string but still don't get idea how to fix. Pls help me!

Do I need to type in the server name or just local host?

Here's the gist of your problem. I see that you're using localhost as your database server in your connection string; does the database server on localhost have a user named cfeuser? Does it have the same password? Hell, is the database even installed there?

What do you mean by C# application? A stand-alone application written on C#? If yes, you can't show it on a browser.

ValidationGroup/CausesValidation in User Control

the_smiths4-Aug-09 15:36

4-Aug-09 15:36

I have a login User Control on my masterpage, and many pages one being a Contact Page.

When you are on the Contact page, the button on the Contact page will not fire the RequiredFieldValidators on the Login User Control, which is correct.

However, when you click the button on the Login User control, it will fire the RequiredFieldValidators on the Contact page, which I do not want.

Now I've tried putting them each in different ValidationGroups, and that didn't work.

I also tried removing all the validation fron the User Control and setting the CausesValidation to False, and that didn't work.

As always any replys, will be very much appreciated.

Thanks,

Hi,

My ASP.Net project uses DirectorySearcher to do a r/w operation against the Active Directory server instance. I have a stacktrace below of an error that I encounter when my DirectorySearcher instance calls FindAll(). I was wondering if this has got to do with permissions that I may not have to perform this kind of operation. Appreciate any help, thanks.

Nunit and unit testing of ASP.NET application [modified]

Hi all,
Need your suggestions

How should i approach testing functions in a ASP.NET application.
Its not integration testing but a unit testing(functions) But the problem is

It is nearly impossible to isolate a function due to dependencies
Many funcition are expecting other objects like Page Class context, Configuration settings many more complex objects like session context... etc

now how can i test this methods using Nunit framework
how should i initialized these objects ?
should i use mock object concept ?
is Nunit framework appropriate tool for writing the test cases ?

Please suggest

Thanks and Regards
Sandeep

If you write good code, then your business tasks will be isolated from UI, and can be tested.

Thanks Chris for your reply

Thats the problem UI layer is having business rules implemented making quite hard to test the application.
We are going to rewrite the application using MVC architecture but before to that we need to write Nunit test cases for existing application.

You need to isolate the dependencies. Separate the code into several projects and have a single project for all your ASPX files. Now you can write tests for the other projects. Other projects should not get a reference to System.Web.

Sandeep Akhare wrote:

Probably yes. You need to create an interface which wraps HttpContext. Inject this interface as a dependency to your business classes. Read more about dependency injection[^].

In your test cases, you can mock this interface and set expectations. I suggest Rhino Mocks[^] for mocking.

It is a wise idea to program to interfaces than implementations.

Yes. Its a great piece of work.

You mean to seperate the business layer from UI only for Testing purpose ?

for other suggestions i need to look in to them.

Separating business logic from UI is good not only for testing but also for improved maintainability. If you have business logic tied close to UI, it will be hard to write automated test cases. So the first step in your case would be to re-factor code to support automated testing.

Hi Navneeth,

We are planning to re-factor the application for next release.
But for current application i have to write the test cases for such complex application.

I read the links you have mentioned but still i am not able to conclude anything

1. Wraping of httpContext :- does it mean creating the app domain for your application ?
2. inserting the dependency object still i am not sure how i will insert it ?

Problem is
Page is derived from one base class which is derived from another base class nad interfaces
There are many properties and objects some of these properties are readonly like sessionContext

Thanks and Regards

hi,
In my project, i have some roles like Department manager, Project manager, team leader,etc. Each member inroled in the role have some rights to view the progress of the on going project of the company.

i want to assign some rights to each group of users like team leader can only view the progress of part of his project & can take action for all the members in his team(assign work among members), on the other hand, project manager can view all the teams working under his project(can take action to all members working under him), same to the department manager can view all the projects of the department(same actions he can perform).

help me making some class hierarchy of my application which would help me.
at the time of login and got the role of the incoming user,now how i work over the controls e,g, same grid for all users but if project manager view the form it will only show the info of his project and if depart manager get login it will show all projects of the whole department.

i am looking for some "multi layer architecture" for the application.

looking for reply.

Hi...

See class and everything you can design as per your requirement.

I am giving answer to your last question....

while binding grid or dropdown each time u have to pass RoleId....& based on this role id only you fetch record from database only....

Hope your DB design will be fine so that u can use this roleid with inner join to other table.

but you do everything at db level only...

so if different different user will login they can see their related data only.
