  • ASP Function that returns result from stored procedures

    - by Brad
    I am working on a project that requires me to hop into to separate DB's. So I have figured that I need to have multiple functions inside of my VB page. The only problem I am having,is I am not to sure how to get this all accomplished. So far I have figured out the overall structure, just need help implementing that structure. Here is my idea: The main Function would call two other functions. We can Call them Sub Function 1 and Sub Function 2. So, the main Function takes the saved sessions information for the E-mail address and dumps in into Sub Function 1. It needs to open up a new connection to the db/stored procedure and RUN the following procedure and then return the result. Here is the stored procedure and what i think is correct. CREATE PROCEDURE WEB_User ( @EMAIL_ADDRESS varchar(80) = [EMAIL_ADDRESS] ) AS SELECT MEMBER_NUMBER FROM WEB_LOGIN WHERE EMAIL_ADDRESS = @EMAIL_ADDRESS So my question is, what is the function suppose to look like? how do I send the session information to the procedure? and finally, how do I return the stored procedure results and push back into the main function so it can be carried into sub function 2? Thank you in advance for your help... I really appreciate it!

  • ASP.NET Thread Safety in aspx.cs code behind file

    - by Tim Michalski
    I am thinking of adding a DataContext as a member variable to my aspx.cs code-behind class for executing LinqToSql queries. Is this thread safe? I am not sure if a new instance of this code-behind class is created for each HTTP request, or if the instance is shared amongst all request threads? My fear is that I will get 10 simultaneous concurrent http requests that will be using the same database session. public partial class MyPage : System.Web.UI.Page { private DataContext myDB = new DataContext(); protected void MyAction_Click(object sender, EventArgs e) { myDB.DoWork(); } }

  • Render asp.net repeater as-and-when chunks of html is ready (streaming)

    - by sash
    The problem is to render huge reports. Basically we have lots of data that get rendered in html reports (mostly using repeater or gridview). As it so happens, the data started out small and now we have tons of it. There are lots of such reports already built so total rewrite is not an option. Heck, the business is not even letting us page the data. Now server memory is shooting up each time we try to render some reports. So the question is - is there some way we can bind data to repeater and have it stream html to browser as and when chunks are ready? That way we hope to not bring all that data into app server at once. I'm thinking we'll use a datareader or something to get parts of data and render it to browser. Any pointers, links, ideas?

  • ASP.NET auto submits form with only one textbox

    - by MartinHN
    Hi, look at this code: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <input type="text" /> </form> </body> </html> When I hit the enter key, when the input box has focus - the form submits. If I add another input box it doesn't submit. How can I avoid the auto submit when there's only one input box?

  • ASP.Net Roles: Page-Level Security Question

    - by jlrolin
    We're currently in the process of re-creating a brand new security model that dwarfs our existing process. Right now, we plan on grabbing a user's roles during the login process and then using a Base Page class to check if the user has the role of the corresponding page the user is navigating to. We can limit the menu's options by the user's roles as well, but we have had problems with users navigating to pages in our system by typing them in or having old bookmarks. Obviously, we need some sort of page level access. A simple function in our Base Page class that checks the role in the Arraylist against the page's assigned role would work, but I was wondering if there was any built-in functionality to support this or a cleaner solution possibly.

  • unsetting application role in classic ASP

    - by user303526
    Hi, I'm trying to unset an application role but have been failing miserably. I was able to get the cookie value after setting (sp_setapprole) the application role. But I haven't been able to use that cookie (type varbinary / byte array) in my query to unset using sp_unsetapprole. If it was any other stored procedure it wouldn't have been a problem. I was able to use Command object and create a parameter which takes data type input of adVarBinary (204) and execute the command line.. but to the Server the query goes as below. exec sp_executesql N'sp_unsetapprole @P1 ',N'@P1 varbinary(36)',0x01000000CD11697F8F0ED3627BC1DAD25FB9CEB3A2EC5B289C658235E510CD9F29230000 Since sp_setapprole and sp_unsetapprole have to be run ad hoc, the sql server is failing to run this line. And I'm finding it hard to append varbinary cookie value to a simple query such as 'sp_unsetapprole ' & varKookie so it runs "directly" on to the server. Any kind of suggestions are welcome. Thanks, Nandagopal

  • ASP.NET MVC v1 project upgraded to VS 2010 no longer will debug. Why?

    - by Todd Brooks
    I'm getting the message "The breakpoint will not currently be hit. No symbols have been loaded for this document." I have a S#arp Architecture project (ASP.NET MVC v1) that has been opened and upgraded to be used in VS 2010. I can no longer debug the project. I'm running Windows 7 Ultimate x64 and Visual Studio 2010 Ultimate. I have IE set to be my default browser. I have the build set to debug. System.Web.Mvc is referenced in my project's lib dir. I've cleaned the solution. I've recompiled the solution. It's set to use .NET Framework 3.5. PDBs are being created and dropped into the bin directory with the DLLs. Any help will be greatly appreciated.

  • How practical to change MVC app from traditional authentication to cookieless?

    - by Phil.Wheeler
    I have an application written in MVC that uses your regular .Net Forms Authentication. There's nothing particularly new or exciting going on with it. My client has now asked that users be able to log in to the app on the same machine but in different browsers, or different tabs within the same browser. To my mind, he's asking for a scope change to have authentication moved to cookieless instead of its current design. Not having had any experience with doing this in MVC, I'm curious to know before I get started how much hurt I'm in for by trying this. Are there better ways to do it? What should I consider? Any advice appreciated.

Am I missing something here maybe? Kind regards, Mark

  • Dynamically Adding ASP.NET Web Forms Controls Loses State on Page Refresh

    - by Geetha
    I am creating dynamic label and textbox based on the number of values from the database for the selected item of the dropdownlist. Then the dynamic labels will have the names and the text box with the values. To retain the values of these controls im using Page_init event. So im using cache to hold the selectteditem from the dropdownlist. Problem: The process is going fine. But if i try to refresh the page no items are selected in the dropdown list but the cache is not getting clear so using this cache value dynamic control are creating.

As following: I created an 'onclick' event in jQuery for the DIV as well: $('#divOne').click(function() { alert('You clicked on the DIV element'); }); My goal is to trigger this event when the DIV area is clicked (working fine), BUT- When the HyperLink is clicked, I need the page to redirect WITHOUT triggering the DIV 'onclick' event (can use JavaScript or jQuery as needed). Thanks all!

This is very strange and i want the page to postback without any error message when i click undo.how to achieve it.

  • Is a Multi-DAL Approach the way to go here?

    - by Krisc
    Working on the data access / model layer in this little MVC2 project and trying to think things out to future projects. I have a database with some basic tables and I have classes in the model layer that represent them. I obviously need something to connect the two. The easiest is to provide some sort of 'provider' that can run operations on the database and return objects. But this is for a website that would potentially be used "a lot" (I know, very general) so I want to cache results from the data layer and keep the cache updated as new data is generated. This question deals with how best to approach this problem of dual DALS. One that returns cached data when possible and goes to the data layer when there is a cache miss. But more importantly, how to integrate the core provider (thing that goes into database) with the caching layer so that it too can rely on cached objects rather than creating new ones. Right now I have the following interfaces: IDataProvider is used to reach the database. It doesn't concern itself with the meaning of the objects it produces, but simply the way to produce them. interface IDataProvider{ // Select, Update, Create, et cetera access IEnumerable<Entry> GetEntries(); Entry GetEntryById(int id); } IDataManager is a layer that sits on top of the IDataProvider layer and manages the cache interface IDataManager : IDataProvider{ void ClearCache(); } Note that in practice the IDataManager implementation will have useful helper functions to add objects to their related cache stores. (In the future I may define other functions on the interface) I guess what I am looking for is the best way to approach a loop back from the IDataProvider implementations so that they can access the cache. Or a different approach entirely may be in order? I am not very interested in 3rd party products at the moment as I am interested in the design of these things much more than this specific implementation. Edit: I realize the title may be a bit misleading. I apologize for that... not sure what to call this question.

  • asp.net Web server control with child controls, event not firing

    - by bleeeah
    I have a simple web control (TaskList) that can have children (Task) which inherit from LinkButton, that can be added declaratively or programatically. This works ok, but I can't get the onclick event of a Task to be fired in my code behind. The code .. [ToolboxData("<{0}:TaskList runat=\"server\"> </{0}:TaskList>")] [ParseChildren(true)] [PersistChildren(false)] public class TaskList : System.Web.UI.Control { //[DefaultProperty("Text")] public TaskList() {} private List<Task> _taskList = new List<Task>(); private string _taskHeading = ""; public string Heading { get { return this._taskHeading; } set { this._taskHeading = value; } } [NotifyParentProperty(true)] [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public List<Task> Tasks { get { return this._taskList; } set { this._taskList = value; } } protected override void CreateChildControls() { foreach (Task task in this._taskList) this.Controls.Add(task); base.CreateChildControls(); } protected override void Render(HtmlTextWriter writer) { writer.Write("<h2>" + this._taskHeading + "</h2>"); writer.Write("<div class='tasks_container'>"); writer.Write("<div class='tasks_list'>"); writer.Write("<ul>"); foreach (Task task in this._taskList) { writer.Write("<li>"); task.RenderControl(writer); writer.Write("</li>"); } writer.Write("</ul>"); writer.Write("</div>"); writer.Write("</div>"); } } public class Task : LinkButton { private string _key = ""; public string Key { get { return this._key; } set { this._key = value; } } } Markup: <rf:TaskList runat="server" ID="tskList" Heading="Tasks"> <Tasks> <rf:Task Key="ba" ID="L1" Text="Helllo" OnClick="task1_Click" runat="server" /> </Tasks> </rf:TaskList> The Onclick event task1_Click never fires when clicked (although a postback occurs).

  • NET Framework Validation Library

    - by Kane
    As I see it most applications have a requirement for some form of validation and a number of fantastic free offerings are available (I.E., Fluent Validation, Validation Block, Spring, Castle Windsor, etc). My question is why does the .NET Framework not include any inbuilt validation libraries? I am aware the .NET Framework allows a developer the ability to build their own validation libraries/methods/etc. and anything provided as part of the .NET Framework would not always meet everyone’s needs. But surely something could have been included? ASP.NET has a minimal set of validators but these have not really been extended since .NET 2.0 was released.

  • Conditional skin file in ASP.Net Theme based off of browser

    - by Dan Appleyard
    Is there a way to use a skin file in a theme only when a certain browser is used? The theme stays the same, I just want skin A to apply when a certain browser is used, and skin B when another browser is used. I know I can have server-side code to check and then set the SkinId of the control to either or, but is there another, more global way? Thanks
