  • Request for the permission of type 'System.Web.AspNetHostingPermission' failed when compiling web si

    - by ahsteele
    I have been using Windows 7 for a while but have not had to work with a particular legacy intranet application since my upgrade. Unfortunately, this application is setup as an ASP.NET Website project hosted on a remote server. When I have the website open in Visual Studio 2008 and try to debug it I get the following compiler error: Request for the permission of type 'System.Web.AspNetHostingPermission' failed To resolve this issue on Windows Vista machines, I would change the machine's .NET Security Configuration trust level to full for the local intranet (fix outlined here). I believe this configuration utility relied upon the mscorcfg.msc which from some cursory research appears to be apart of the .NET 2.0 SDK. I have tried to follow the instructions from this Microsoft Support article running the command below to no avail. Drive:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\caspol.exe -m -ag 1 -url "file:////\\computername\sharename\*" FullTrust -exclusive on Presently, I have the following .NET and ASP.NET components installed on my machine Microsoft .NET Compact Framework 2.0 SP2 Microsoft .NET Compact Framework 3.5 Microsoft .NET Framework 4 Client Profile Microsoft .NET Framework 4 Extended Microsoft .NET Framework 4 Multi-Targeting Pack Microsoft ASP.NET MVC 1.0 Microsoft ASP.NET MVC 2 Microsoft ASP.NET MVC 2 - Visual Studio 2008 Tools Microsoft ASP.NET MVC 2 - Visual Studio 2010 Tools Do I need to install the .NET 2.0 SDK? Am I issuing the caspol command incorrectly? Is there something else that I am missing?

  • radiobutton not working in allkeys

    - by gerred
    i have a radiobutton built throught my code. this is the code for that. dim 1 as intereger = 0 Dim rd As New RadioButton rd.ID = "rd_" & i rd.GroupName = "rd_g" TD.Controls.Add(rd) i = i+1 the reason i gave groupname is so that when i select the radiobutton only one is selected at one time and not all. but this creates a problem in my save button. here's the code for that - For Each key As String In Request.Form.AllKeys If key.Contains("rd_") Then Dim temp1 As String = key.Substring(key.IndexOf("rd_")).Replace("rd_", "") Dim id As Integer = Val(temp) If id 0 Then SQL = "select .... " In the Request.Form.AllKeys I only get the groupname and not the ID of the radiobutton that i need. what am i doing wrong?

  • asp.net CustomValidator never fires OnServerValidate

    - by Bryce Fischer
    I have the following ASP page: <asp:Content ID="Content2" ContentPlaceHolderID="ShellContent" runat="server"> <form runat="server" id="AddNewNoteForm" method="post""> <fieldset id="NoteContainer"> <legend>Add New Note</legend> <asp:ValidationSummary ID="ValidationSummary1" runat="server" /> <div class="ctrlHolder"> <asp:Label ID="LabelNoteDate" runat="server" Text="Note Date" AssociatedControlID="NoteDateTextBox"></asp:Label> <asp:TextBox ID="NoteDateTextBox" runat="server" class="textInput" CausesValidation="True" ></asp:TextBox> <asp:CustomValidator ID="CustomValidator1" runat="server" ErrorMessage="CustomValidator" ControlToValidate="NoteDateTextBox" OnServerValidate="CustomValidator1_ServerValidate" Display="Dynamic" >*</asp:CustomValidator> </div> <div class="ctrlHolder"> <asp:Label ID="LabelNoteText" AssociatedControlID="NoteTextTextBox" runat="server" Text="Note"></asp:Label> <asp:TextBox ID="NoteTextTextBox" runat="server" Height="102px" TextMode="MultiLine" class="textInput" ></asp:TextBox> <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="Note Text is Required" ControlToValidate="NoteTextTextBox">*</asp:RequiredFieldValidator> </div> <div class="buttonHolder"> <asp:Button ID="OkButton" runat="server" Text="Add New Note" CssClass="primaryAction" onclick="OkButton_Click"/> <asp:HyperLink ID="HyperLink1" runat="server">Cancel</asp:HyperLink> </div> </fieldset> </form> </asp:Content> and the following code behind for the CustomValidator1_ServerValidate() method: protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args) { if (string.IsNullOrEmpty(args.Value.Trim())) { args.IsValid = false; CustomValidator1.ErrorMessage = "Note Date is Required!"; return; } DateTime testDate; if (DateTime.TryParse(args.Value, out testDate)) { args.IsValid = true; CustomValidator1.ErrorMessage = "Invalid Date!"; } } It never seems to fail validation no matter what I put in the text box... Should mention this is ASP.NET 2.0

  • Wireframe mock-up software

    - by Dave Jarvis
    Requirements Looking for wireframe mock-up software for web apps with the following constraints: Desktop application (supports Linux) (can be online) Export all pages to separate image files (PNG or SVG preferred) Template for all pages Drag and drop standard HTML widgets for <forms> Tabbed panels (that allow content on the different tabs) Shuttle controls Saves in an XML format (XSLT could convert to HTML) Widget alignment and resizing (relative to other widgets) Under $100.00 USD Examples That come close: Cacoo - Not a desktop application; does not have a true tabbed panel widget Pencil - Export feature has serious bugs (missing text); no template? Balsamiq - Installation proved cantankerous on Linux (due to Adobe AIR) Mockingbird - No shuttle controls; no auto-resize of widgets Pencil & paper - Not a good look for a formal document presented to clients Any others that meet the requirements?

  • Is there more to HTML forms than http://www.w3schools.com/html/html_forms.asp ?

    - by mawg
    I am creating a form designer. It will generate PHP code which will produce an HTML form. Users will fill in fields and the PHP will store user input in a MySql database (and, of course, they can use the designer to generate forms which query the database). I am using Borland C++ Builder (very similar to Delphi & and you can get the same idea from VB, MSVC, Qt ... any IDE with a RAD GUI designer). Looking at the W3C page http://www.w3schools.com/html/html_forms.asp it seems that the components I can use for my form and retrieve data from are - edit box / TEdit / <input type="text" - memo / TMemo / <input type="textarea" - check box / TCheckBox / <input type="CheckBox" - Combo box / TComboBox / <select ... <option... - Radio group / TRadioGroup / <input type="radio" - Group box / TGroupBox / <fieldset ... <legend ... - Panel / TPanel / <fieldset ... I am unsure whether to allow button / TButton/ input type="button" - other than a single submit button which my form designer program automatically adds to the end of the generated form. But my real question is - did I miss any? It might be nice to have masked edit which only accepts numbers, or maybe some form of "spin control" (TUpDown, or slider + linked read only TEdit), so that the user can click & hold to increment/decrement an integer value. And a calendar component would be nice. Very important: I want to implement it all server-side in PHP, so no client-side JS or Ajax or the likes. If there anything else that I can add to make my generated forms look more impressive in the browser?

  • Why do Asp.net timers/updatepanels leak memory and can it be fixed/worked around?

    - by KallDrexx
    I have built a suite of internal websites for our company to manage some of our processes. I have been noticing that these pages have massive memory leaks that cause the pages to be using well over 150mb of memory, which is ridiculous for a webpage that consists of a single form and a GridView that is displaying 7-10 rows of data at a time, sometimes with the data not changing for a whole day. This data does need to be refreshed on a semi-regular basis so that we always see the latest results and can act on them. After some testing it appears that the memory leak is extremely easy to reproduce, and very noticeable. I created a page with the following asp.net markup: <body> <form id="form1" runat="server"> <div> <asp:scriptmanager ID="Scriptmanager1" runat="server"></asp:scriptmanager> <asp:Timer ID="timer1" runat="server" Interval="1000" /> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> </ContentTemplate> </asp:UpdatePanel> </div> </form> </body> There is absolutely no code behind for this. This is the entirety of the page. Running this site in Chrome shows the memory usage shoot up to 25 megs in the span of 20-30 seconds. Leaving it running for a few minutes makes the memory go up to the 70 megs and such. Am I using timers and update panels wrong, or is this a pure Asp.net issue with no work around?

  • Can't get FCKEditor to work in a virtual directory.

    - by AngryHacker
    I have a WebForm that contains the following definition for the FCKeditor: <FCKeditorV2:FCKeditor ID="txtBody" runat="server" BasePath="/fckeditor/" Height="480px" ToolbarSet="WebCal1" > </FCKeditorV2:FCKeditor> This works fine in my VS2008-based web application. However, when I deploy it to a Virtual Directory in IIS, it looks for the FCKEditor files (e.g. javascript, stylesheets, etc...) in the /fckeditor folder, not in the /MyVirtualDir/fkceditor. I've tried changing the BasePath to ~/fckeditor/, but then it won't work on my dev machine. What is the right way to go, so that the FCKEditor maps onto the right directory. In my project the fckeditor directory is right off the root.

  • Binding custom property in Entity Framework

    - by deverop
    I have an employee entity in my EF model. I then added a class to the project to add a custom property public partial class Employee { public string Name { get { return string.Format("{0} {1}", this.FirstName, this.LastName); } } } On a aspx form (inside a FormView), I want to bind a DropDownList to the employee collection: <asp:Label runat="server" AssociatedControlID="ddlManagerId" Text="ManagerId" /> <asp:DropDownList ID="ddlManagerId" runat="server" DataSourceID="edsManagerId" DataValueField="Id" DataTextField="Name" AppendDataBoundItems="true" SelectedValue='<%# Bind("ManagerId") %>'> <asp:ListItem Text="-- Select --" Value="0" /> </asp:DropDownList> <asp:EntityDataSource ID="edsManagerId" runat="server" ConnectionString="name=Entities" DefaultContainerName="Entities" EntitySetName="Employees" EntityTypeFilter="Employee" EnableFlattening="true"> </asp:EntityDataSource> Unfortunately, when I fire up the page, I get an error: DataBinding: 'System.Web.UI.WebControls.EntityDataSourceWrapper' does not contain a property with the name 'Name'. Any ideas what I'm doing wrong?

  • Databound Checkbox list with textboxes in a webform

    - by zSysop
    Hi all, I'm having trouble coming up with a solution for the following problem and i was wondering if someone here would help me out. I need to pull a list of supplies from a db table and list them along with two textboxes (one for quantity, and another for manufacturer) so the list would look something like this. checkbox for supply 1 | Quantity | Manufacturer checkbox for supply 2 | Quantity | Manufacturer .. I also need to store all of the checked items in a db table. I'm not sure how i should go about doing this. I've heard some talk about a repeater control being useful but i've not come across any examples that do this type of thing. Thanks in advance

  • Modifying listbox values with jQuery in WebForm not posting back

    - by Peter
    When hitting a button, an error would occur: System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. --- System.ArgumentException: Invalid postback or callback argument. Event validation is enabled using in configuration or in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. I then added EnableEventValidation="false" into my @Page directive, which fixed the error. Now after manipulating the listbox, the new values in the listbox are not posted back to the server. How can I solve this?

  • Formmail redirect question

    - by Elliot
    So I'm using a basic formmail script. Within the script I'm using a redirect variable. The value of the redirect is something like,"http://www.mysite.com/NewOLS_GCUK_EN/bling.aspx?BC=GCUK&IBC=CSEE&SIBC=CSEE" When the redirect action happens however, the url appears in the browser as: http://www.mysite.com/NewOLS_GCUK_EN/bling.aspx?BC=GCUK&amp;IBC=CSEE&amp;SIBC=CSEE you can see the &'s are replaced with "& a m p ;" is there any way to fix this? Thanks! -Elliot

  • Populate Dynamically created ASPX Page

    - by Sandhurst
    Well The title might be a lil confusing, what I am currently doing is creating an aspx form dynamically and saving its data by using Server.Transfer("PrssPage.aspx"). On ProcessPage.aspx I am using the Previous Page property to save the data entered by the user using the dynamically created form. Each Dynamic Form is provided an ID for example 123.aspx Now what I want to achieve is to repopulate the dynamically created aspx page with the user input values from database, plz note here that I do not have an aspx.cs page getting dynamically generated. I am only generating aspx page. Any suggestion ?

  • jeditable in an ASP.NET web form

    - by Barney
    Can someone explain to me how you would use jeditable with an ASP.NET web form (and C# codebehind). I've got a bit of experience with web forms but not very complicated stuff, and haven't used much jquery before, and this is just puzzling me. I understand how to put it in and attach it to the element you want to be editable, it's what jeditable does when you submit the text field that I don't get. How do you handle that in the webform in order to save the changed text? Hope someone understands my issue... Cheers!

  • One Update Panel vs. Multiple Update Panels

    - by mattruma
    I have an ASP.NET web page that displays a variety of fields that need to be updated best on certain conditions, button clicks and so on. We've implemented AJAX, using the ASP.NET Update Panel to avoid visible postbacks. Originally there was only one area that needed this ability ... that soon expanded to other fields. Now my web page has multiple UpdatePanels. I am wondering if it would be best to just wrap the entire form in a single UpdatePanel, or keep the individual UpdatePanels. What are the best practices for using the ASP.NET UpdatePanel?

  • How to detect hidden field tampering?

    - by Myron
    On a form of my web app, I've got a hidden field that I need to protect from tampering for security reasons. I'm trying to come up with a solution whereby I can detect if the value of the hidden field has been changed, and react appropriately (i.e. with a generic "Something went wrong, please try again" error message). The solution should be secure enough that brute force attacks are infeasible. I've got a basic solution that I think will work, but I'm not security expert and I may be totally missing something here. My idea is to render two hidden inputs: one named "important_value", containing the value I need to protect, and one named "important_value_hash" containing the SHA hash of the important value concatenated with a constant long random string (i.e. the same string will be used every time). When the form is submitted, the server will re-compute the SHA hash, and compare against the submitted value of important_value_hash. If they are not the same, the important_value has been tampered with. I could also concatenate additional values with the SHA's input string (maybe the user's IP address?), but I don't know if that really gains me anything. Will this be secure? Anyone have any insight into how it might be broken, and what could/should be done to improve it? Thanks!

  • jQuery dynamic field classes not being assigned as desired.

    - by Simon
    Hello, I'm working on a fancy login page with 4 unique states attributed through classes for each field (normal, focus, active-on, active-off). Normal is the default style. Focus is the focus style when nothing is typed. Active-on is the focus style when something has been typed. Active-off is for field that have user text in them, but are not focused right now. Here's a demo to help you understand what I'm doing: http://www.controlstack.com/login My JS is working almost correctly (thanks to some folks on this site), except in 2 cases: If I enter something in the username field, then tab over to the password field, it does not add the ".focus" class to the password field. If I blur out of the username field, then focus back on it, enter a few characters, then delete them, it does not add the ".focus" field. Here's my code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" dir="ltr"> <head> <title>Login</title> <style> input.field {height: 39px; width: 194px; background: url(login-fields.png) no-repeat; overflow: hidden; border: none; outline: none; float: left; margin-right: 7px;} input.field#username {padding: 0 12px;} input.field#username.focus {background-position: 0 -39px;} input.field#username.active-on {background-position: 0 -78px;} input.field#username.active-off {background-position: 0 -117px;} input.field#password {background-position: -218px 0; padding: 0 12px;} input.field#password.focus {background-position: -218px -39px;} input.field#password.active-on {background-position: -218px -78px;} input.field#password.active-off {background-position: -218px -117px;} input.field#go {background-position: -436px 0; width: 88px; margin: 0; cursor: pointer;} </style> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function() { loginField = $('.field'); firstField = $('.field.first'); firstField.focus(); loginField.focus(function(){ loginVal1 = loginField.val(); if (!loginVal1){ $(this).removeClass('active-off').addClass('focus'); } else { $(this).removeClass('active-off').addClass('active-on'); } }); loginField.live('keydown', function(){ $(this).addClass('active-on').removeClass('active-off'); }).live('keyup', function(){ $(this).toggleClass('active-on', $(this).val() != ''); }) loginField.blur(function(){ loginVal2 = loginField.val(); if (!loginVal2){ $(this).removeClass('focus').removeClass('active-on'); $(this).val(''); } else { $(this).removeClass('focus').removeClass('active-on').addClass('active-off'); } }); }); </script> </head> <body> <h1>Login to your account</h1> <form method="post" action="/"> <fieldset> <input type="text" class="field first focus" id="username" /> <input type="text" class="field" id="password" /> <input type="submit" value="" class="field" id="go" alt="login" title="login" /> </fieldset> </form> </body> </html> Your help is much appreciated!

  • Finding the FORM that an element belongs to in JavaScript

    - by Magnus Smith
    How can I find out which FORM an HTML element is contained within, using a simple/small bit of JavaScript? In the example below, if I have already got hold of the SPAN called 'message', how can I easily get to the FORM element? <form name="whatever"> <div> <span id="message"></span> </div> </form> The SPAN might be nested within other tables or DIVs, but it seems too long-winded to iterate around .parentElement and work my way up the tree. Is there a simpler and shorter way? If it wasn't a SPAN, but an INPUT element, would that be easier? Do they have a property which points back to the containing FORM? Google says no...
