How do i configure connection string for Asp.Net Membership Provider? Do i have to write it by hand or any tool is available in Visual Studio where i can specify connection string as well as algorithm used to store password? I read one article and it specifies this connection string :-
<configuration>
<connectionStrings>
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=localhost;Initial Catalog=appservicesdb;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
</configuration>
This LocalSqlServer name doesn't sound too intuitive. How do i change this?

View 1 RepliesIn IIS7 I don't find any possibility to keep a website from responding to it's IP address as soon there is SSL set up for this website. I did not add the IP address as hostname for this website and so would expect that the site does only respond to it's given hostname(s). Unfortunately the website won't work if requested via it's IP address, so I have to disable IP address as hostname somehow.
Another issue is that IIS 7 does not display the "secure connection obligatory" error page anymore if secure connection is mandatory for a website. Is there any way to get this error page being displayed, just like it was in IIS6 ?

View 3 RepliesI have this SQL Select statement to select the basket id where the user id equals a specific ID.I want to store the result of the query in a variable, so I thought I could have done:
BasketPage.SelectCommand="SELECT BasketID FROM tblBasket WHERE (UserID = '9f96bd94-91b9-4328-8214-4eac179c3a26')"
var BasketID = BasketPage.ExecuteScalar().ToString();
But apparently I need to create a new instance of an SQL Command for it to work, how can I do this for the BasketPage Select Command?
1) All users can browse open web site content.
2) To access memebrs area users must login.
3) Users can create , edit/update, delete there profile/information only.
4) Users can see / view other users profiles.
5) Admin can browse, create, edit/update, delete an any profiles.
I found many different ways to implement it, but what the best practice. May be you can point me in right direction.
Application Web based, MsSQL 2005, .NET 3.5, Server 2003.
I was looking to build an application with the scenario:
1. The application is a Shared PowerPoint Presentation
2. There would be 2 users for the application, Admin and Client
3. Admin can upload presentations
4. Only Admin can control the flow of presentation and cLient can just see the changes
5. As-In Admin can select next slide or previous slide and correspondingly Client configuration changes
I was thinking of updating current values in Database and using AJAX for updates on Client end. But I want a notification kinda thing that would notify the Client as soon as the Admin changes slides.
My scenario is this:
I have asp.net page which having the drop down control with Product list. in database my Product Table has fields as ProductId, Product Name and Price. where as I have filled this drop down control by this method:
private void FillProducts()
{
List<Product> productList = objProductManager.GetProducts();
if (productList.Count > 0)
{
drpProducts.DataSource = productList;
drpProducts.DataTextField = "ProductName";
drpProducts.DataValueField = "ProductId";
drpProducts.DataBind();
}
}
Which is working perfect. But i want to get selected product Price value on client side. for that I don't want round trip at server to get that. is any property of dropdown control other than DataTextFeild Or DataValueField to hold the Price Field of product ? so that i would avoid to go back at server. Or suggest any remedy for the same.
I am using ajax.beginform. i am inserting and updating records using ajax and showing the inserted or updated value in the div above the div containing form. I need to apply validtion on these values.what is the recomended validation framework for this scenario. i have problems pushing validation messages to the form as i can only update one div that is indicated in updatetargetid parameter of ajax.beginform and this value in my case is set to div displaying the updated/inserted data
i'm new with design patterns and i'm not sure if in this situation i can use a composite pattern.
The scenario is a web application for an address book : the address book cointains AddressBoookItem, generalization for Contact and ContactGroup. The last one is the composite object containing a collection of AddressBoookItem.
With these scenario i'm sure that this is a composite pattern, but what is confusing me is that a contact may belong to many contactgroup. Does this request change the situation? Till now i thought that between the Leaf object and the Composite (in the composite pattern) there was a 1-to-m relationship (a composite may contains many leaf but a leaf is contained in only one composite object). Can i still use the composite pattern ? And, the last question,
How could i represent my scenario in a relational database? One table for the entire hierarchy or two table (Contact and ContactGroup) with a m:n relationship between them ?
I want the select statement for the above scenario.

How can I maintain using data annotation attributes for validations in mvc3 different requirement for edit and create in an elegant manner. I have an different edit and create requirement.
I want to track equipment between three types of allocations. A piece of equipment can be allocated to an employee, to a customer facility or to a warehouse.
I have an equipment table, employee table, a customer table and warehouse table. Warehouse is where equipment is temporarily held and shared between multiple employees, it is a holding area.
Obviously each equipment item can only be allocated to one employee, customer or warehouse.
My original thinking was to make a table for EquipmentAllocations where it linked the EquipmentID and the id of the employee, customer or warehouse (all guids).
Eventually I will need to query the equipment to see where it is located/allocated. I will also need to query the employees to check what equipment is allocated to them.
I am trying to figure out the best way to handle this and I am looking for some guidance. I am sure many of you have had situations similar to this that you could draw upon to offer up some advice.
SaveChanges can generate an UpdateException when an object added to the ObjectContext cannot be successfully created in the data source. This can happen if a row with the foreign key specified by the relationship already exists. When this occurs, you cannot use Refresh to update the added object in the object context. Instead, reload the object with a value of OverwriteChanges for MergeOption.
In a table, a foreign key column can have a single value multiple times. e.g. DepartmentID foreign key in Users Table: More than one User can have same DepartmentID foreign key.
So how can this cause an UpdateException ?
I have two List's that contain a object of Tag like List<Tag> i need to find excluded and included to do an update operation how do find the difference in them both since they contain a Tag object. Can you use Contains function with a Tag object inside the list.

I have created a great stand-alone web form in asp.net utilizing many jQuery features and CSS. It works fine. When I re-create it as a web content form as part of a MasterPage, my jQuery and javascript is completely ignored.
I am referencing the pertinent jQuery and CSS in my of the MasterPage. I have a content placeholder at the bottom of the masterpage called "ScriptContent". In my content page, this is where I plug in the various jQuery methods and javascript.
When I view the page source everything is there. However, it's all being ignored so to speak. What am I doing wrong?
I am using ASP.NET MVC with jquery. I have the following MVC Action that returns a partial page on Success. On Application Error, I am not sure what to send it for correctly handling it at the client side.
public ActionResult LoadFilterSet(int filterSetId)
{
try
{
BreadCrumbManager bcManager = this.ResetBreadCrumbManager(this.BreadCrumbManagerID);
GeneralHelper.LoadBreadCrumbManager(bcManager, filterSetId);
ViewData["BreadCrumbManager"] = bcManager;
return View("LoadFilterSet");
}
catch (Exception ex)
{
return Content("");
}
}
Following is my jquery ajax call. Notice that I am checking for the data length to make sure there are no errors. Please suggest me a better way of doing this.
$.ajax({
type: "GET",
dataType: "html",
async: true,
data: ({ filterSetId: selectedId }),
url: link,
contentType: "text/html; charset=utf-8",
success: function(data, textStatus) {
if (data.length > 0) {
// Clear the local filters first.
clearLocalFilters();
$('td.selected-filters table.filters-display').append(data);
}
}
});
I have a question about model binding. Imagine you have an existing database entity displayed in a form and you'd like to edit some details, some properties eg createddate etc are not bound to the form, during model binding, these properties are not assigned to the model as they are not on the http post data or querystrong etc, hence their properties are null. In my controller method for update , Id just like to do
public ActionResult Update( Entity ent)
{
//Save changes to db
}
but as some properties are null in ent, they override the existing database fields which are not part of the form post data, What is the correct way to handle this? Ive tried hidden fields to hold the data, but model binding does not seem to assign hidden fields to the model.
