  • Call up last exception on an ASP.NET error page.

    - by Aren B
    I've got an error page here SiteError.aspx and it's configured correctly in the web.config to go there when unhandled exceptions are encountered. I want to use this page to log the exception that triggered it as well because I only want to LOG the errors that the users encounter (i.e. if SiteError.aspx is ever hit.) This is the code I Have: In the OnLoad(...) in SiteError.aspx Exception lastEx = Context.Server.GetLastError(); if (lastEx != null) log.Error("A site error was encountered", lastEx); However, my log is never showing up in my Output, and If i breakpoint on line 2 (in this example) code execution is never interupted (after letting the exception clear to ASP.NET handling in the debugger.

  • ASP.NET: Moving ViewState to bottom of page

    - by Seb Nilsson
    What are the latest and greatest ways to move ViewState to bottom of the page Can this be done in a IHttpHandler that can be specified in the web.config to intercept requests to "*.aspx"? <httpHandlers> <add verb="*" path="*.aspx" type="MyApp.OptimizedPageHandler" /> <httpHandlers> Other options is that this could be done in a IHttpModule, but that is not as performant, as it will intercept all requests. Also it could be done in an a class deriving from the Page or MasterPage-class, but this is not as modular. Are there any performance penalties to this?

  • Ubiquitous way to get the file system root of a .NET WEB application

    - by Eddie
    Similar to Ubiquitous way to get the root directory an application is running in via C#, but that question seems to be related to Win Forms. How would the same be done for Web Forms? I was using... HttpContext.Current.Server.MapPath("~") This works great for handling HTTP requests but seems not to work if a scheduler like Quartz.NET invokes a job (the problem I am having). The HttpContext.Current is null in that scenario since an actual HTTP request is not made.

  • object not found error with dynamic web forms with (jquery) javscript script

    - by deostroll
    In a normal aspx page I've set up a jquery tab system. When a particular tab shows up I wire up an ajax call to get another html page with the following content. It is simply a form with some javascript inside of it. <!-- demo.htm --> <form method="post" action="post.aspx"> <div id="fields"> Class: <input id="txtclass" name="txtclass" type="text"/> Grade: <input id="txtgrade" name="txtgrade" type="text"/> <input id="btnupdate" value="Update"/> </div> <div id="update"> Reason:<br/> <input id="txtreason" name="txtreason" type="text"/> <br/> Comments:<br/> <textarea id="txtcomments" name="txtcomments"></textarea> <br/> <input type="button" id="btnsave" value="Save"/> </div> <script type="text/javascript"> $(function(){ //all textboxes should be disabled $('#fields input').each(function(i,j){ if(! $(this).is(':button') ) $(this).attr('disabled', 'disabled') }); //update div should be hidden $('#update).hide(); //click event of btnupdate should // be set to show the update div contents // and enable input fields $('#btnupdate').click(function(){ //enable all textboxes $('#fields input').each(function(i,j){ $(this).attr('disabled', ''); }); //hide btnupdate $('#btnupdate').hide(); //show div update $('#update').show(); }); }); </script> </form> The script executes normally and the form is shown as intended. The btnupdate is supposed to show the contents in the update div and load the form for accepting user input. Whenever I hit btnupdate button I get an object not found exception on IE 8. IE 8 asks if it should start up its in-built debuggger. But, even in this debugger I cannot see what the problem is...However on clicking "No" in that dialog the button click function executes properly, and the form is displayed as intended. Is there a better way to resolve the problem?

  • Why does the ASP.Net Web Forms model "suck"?

    - by Daniel Magliola
    I've heard Jeff Atwood, Joel Spolsky, and many other legendary people talk about how the ASP.Net Web Forms model sucks. (So this question is kind of directed to them, hopefully Jeff is reading) Now, I highly respect their opinion, given their background and expertise, but truth be told, I absolutely LOVE ASP.Net. I think the model is brilliant, and it sucks if you have no idea what you're doing, but once you understand how to control ViewState, when to use handlers instead of pages, etc, it is generations ahead of all the other models. So every time I hear someone complain about how it sucks, I can't help ask the same question... Why? What is it that's so bad about it? I appreciate all opinions. I'm assuming there's probably a post at Jeff's blog talking about this too...

  • Web Crawling Sites with Javascripts or web forms

    - by Jojo
    Hello everyone, I have a webcrawler application. It successfully crawled most common and simple sites. Now i ran into some types of websites wherein HTML documents are dynamically generated through FORMS or javascripts. I believe they can be crawled and I just don't know how. Now, these websites do not show the actual HTML page. I mean if I browse that page in IE or firefox, the HTML code does not match what's actually in the IE or firefox. These sites contain textboxes, checkboxes, etc... so I believe they are what they call "Web Forms". Actually I am not much familiar with web development so correct me if I'm wrong. My question is, does anyone in similar situation as I am now and have successfully solved these types of "challenges"? Does anyone know of a certain book or article regarding web crawling? Those that pertains to these advanced type of websites? Thanks.

  • VB.Net: How to fill in a form in a website, then click at a button and download the file using webbr

    - by BasisBit
    I am using a WebBrowser-Control to fill in a webform and then click at a button, this currently results in a standard Download File Dialog (you get these if you download a file using internet explorer), but instead, I have to catch this file and save it automatically with a by me defined name to a specific folder. I am trying to code a little application in vb.net which download the Export-file from my wordpress-blog, and I want to do this completely without user-interaction. Currently everything works, except the downloading of the file. I tried to catch it with the event System.Windows.Controls.WebBrowser.Navigating(ByVal Object, ByVal System.Windows.Navigation.NavigatingCancelEventArgs) but I don't see where to download the file from :( I hope you guys can help me.

  • How to disable vertical bounce/scroll on iPhone in a mobile web application

    - by Kasper Skov
    As the title says, i need to disable vertical bounce on iphone on my mobile web form application. Ive tried alot of different things, but most of them disables my form or horizontal scroll and bounce as well. Any ideas? Im using jquery.mobile btw :) Update: I actually managed to get the code from the first answer working somewhat: function stopScrolling( touchEvent ) { touchEvent.preventDefault(); } document.addEventListener( 'touchstart' , stopScrolling , false ); document.addEventListener( 'touchmove' , stopScrolling , false ); The reason why I couldnt get it to work in the first place, was that there actually was some margin on my body (stupid me). But. As the layout is fluid and im using jquery.mobile and have <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> in the header (I think) it doesnt work properly. The page is zoomed out (view from like a desktop browser) and zooming is disabled. Without the code, the page scales perfectly right from an 50" tv to the smallest nokia on the planet. Am I doing something wrong? Im starting to think the problem is caused by the body/content somehow being over 100% of the viewport. No idea how though.

  • VS2010 and CSS: What is the best strategy to individually position form controls

    - by George
    OK, I have a ton of controls on my page that I need to individually place. I need to set a margin here, a padding there, etc. None of these particular styles that I want to apply will be applied to more than control. What is the bets practice for determining at which level the style is placed, etc? OK, my choices are 1) External CSS file 1A) Using ClientIdMode = Auto (the default) I could assign a unique CssClass value to the ASP.NET control and, in the external CSS file, create a class selector that would only be applied to that one control. 1B) User Client ID = Predicatable In the external CSS file, I could determine what the ID will be for the controls of interest and create an ID selector (#ControlID{Style} ). However, I fear maintenance issues due to including/removing parent containers that would cause the ID to change. 1C) User Client ID = Static. I could choose static IDs for the controls such that I minimize the likelihood of a clash with auto generated IDs (perhaps by prefixing the ID with "StaticID_" and use an external stylesheet with ID selectors. 2) I could place the style right on the control. The only disadvantage here, as I see it, is that style info is brought down each time instead of being cached , which is what I'd get using an external CSS. If a style isn't resused, I personally don't see much benefit to placing it in an external file, though please explain why if you disagree. Is there moire of a reason that "It's nice to have all the CSS in one place?"

  • Where does form processing logic belong in a MVC web application?

    - by AdamTheHutt
    In a web-based application that uses the Model-View-Controller design pattern, the logic relating to processing form submissions seems to belong somewhere in between the Model layer and the Controller layer. This is especially true in the case of a complex form (i.e. where form processing goes well beyond simple CRUD operations). What's the best way to conceptualize this? Are forms simply a kind of glue between models and controllers? Or does form logic belong squarely in the M or C camp? EDIT: I understand the basic flow of information in an MVC application (see chills42's answer for a summary). My question is where the form processing logic belongs - in the controller, in the model, or somewhere else?

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

    - 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: 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 to trust the local intranet. 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?

  • Managing/Storing complex application form

    - by mickyjtwin
    I am developing an online application form, which can be of two categories, either domestic/international. Each different type has commong questions, and also specific questions. They are approx 6 pages/steps of questions. The application form can also be saved at the end of each step, and can be completed at a later date. Some questions will vary depending on answers to previous questions, so there are some complex business rules. In terms of storage of results, would it be best to store the answers in and XML field in SQL? What would be the best way to reference a question to an answer. There is no need for the form to be dynamic in rendering questions etc. e.g. <Application id="123" type="Domestic"> <Answers> <EmailAddress>[email protected]</EmailAddress> <HomePhone>555-5555</HomePhone> <Suburb>MySuburb</Suburb> <Guardians> <Guardian type="Mother"> <FirstName>Mom</FirstName> </Guardian> </Guardians> <Answers> </Application>

  • Populate a form from SQL

    - by xrum
    Hi, I am trying to populate a web from from a SQL table.

End Class Public Class clsPerson 'set SQL connection Dim objFormat As New clsFormat Dim objConn As New clsConn() Dim connStr As String = objConn.getConn() Dim myConnection As New Data.SqlClient.SqlConnection(connStr) Public Function GetPersonDetails() As userDetails 'connection and all other good stuff here Try ' Execute the command myConnection.Open() dr = myCommand.ExecuteReader() ' Make sure a record was returned If dr.Read() Then ' Create and Populate ApplicantDetails userDetails.address1 = dr("address1") userDetails.address2 = objFormat.CheckNull(dr("address2")) userDetails.city = objFormat.CheckNull(dr("city")) .... Else Err.Raise(4938, "clsUser", "Error in GetUserDetails - User Not Found") End If dr.Close() Finally myConnection.Close() End Try Return userDetails End Function i then use GetPersonDetails() function in my backend to populate the form. like so: Dim userDetails as new userDetails userdetails = getPersonDetails() txtAddress.text = userdetails.address1 etc.... however, there are like 50 fields in the User db, and it seems like a lot of retyping... please help me find a better way to do this.

  • Does Security Trimming work with Web Forms Routing?

    - by Slauma
    In my web.config I have configured a SiteMapProvider with securityTrimmingEnabled="true" and on my main master page is an asp:Menu control bound to an asp:SiteMapDataSource. In addition I have configured restricted access to all pages in a subfolder "Admin" (using another web.config in this subfolder). If I put a sitemapNode in Web.sitemap... <siteMapNode url="~/Admin/Default.aspx" title="Administration" description="" > ... only users in role "Admin" will have the menu item related to that siteMapNode. So this is working fine and as intended. Now I have defined a URL route in Global.asax to map the physical file to a new URL: System.Web.Routing.RouteTable.Routes.MapPageRoute("AdminHomeRoute", "Administration/Home", "~/Admin/Default.aspx"); But when I use this route-URL in the SiteMap file... <siteMapNode url="Administration/Home" title="Administration" description="" > ... it seems that security trimming does not work: The menu item is visible for all users. (Access to the page is still restricted though, so selecting the menu item by non-Admin users does not navigate to the restricted page.) Question: Is there any setting I've missed so far to make security trimming working with URL routing in ASP.NET 4.0 Web Forms? Did I do something wrong? Is there any work-around? Thank you for help!

    - by Chris
    This is my first time posting - I greatly appreciate any and all guidance on this subject. Background: I am building a Real Estate web site. I would like to use the free IDX data provided by my local MLS board. The MLS board does not allow me the option of displaying a predefined search and only provides me with a link to the search field. after filling out the search field, I am able to view the results. Goal: I would like to bypass this step and frame the results page into a GoDaddy website I am building, which supports HTML. Here is a link to the search page: http://fgcmls.rapmls.com/scripts/mgrqispi.dll?APPNAME=Fortmyers&PRGNAME=MLSLogin&ARGUMENT=vBSJvLQtMcbg7F0O0KnXDiggv%2F12B0S6Ss9wv4510QA%3D&KeyRid=1 I am trying to only show the listings that appear in my neighborhood. Options include: 1. Property Type - Residential 2. GEO Area - FM11 3. Developments: Fiddlesticks Country Club Once this criteria is entered, I have the page needed to make this project work. Thank all of you for taking the time to read this and for the time you spend helping me out. Best regards, Chris

  • Calling ASP.NET Web API using JQuery ajax - cross site scripting issue

    - by SimonF
    I have a Web API which I am calling using the JQuery ajax function. When I test the service directly (using the Chrome RESTEasy extension) it works fine, however when I call it using the JQuery ajax function I get an error. I'm calling it on port 81: $.ajax({ url: "http://127.0.0.1:81/api/people", data: JSON.stringify(personToCreate), type: "POST", contentType: "application/json;charset=utf-8", statusCode: { 201: function (newPerson) { callback(newPerson); } }, success: function (newPerson) { alert("New person created with an Id of " + newPerson.Id); }, error: function (jqXHR, textStatus, errorThrown) { alert('Error. '+textStatus+'. '+errorThrown); } }); ...but when I trace it using FireBug Lite the response comes from port 82: {"Message":"No HTTP resource was found that matches the request URI 'http://127.0.0.1:82/api/people'.","MessageDetail":"No action was found on the controller 'People' that matches the request."} I think the error is, effectively, due to cross-site scripting being blocked, but I'm not actually cross-site scripting, if you see what I mean. Has anyone else come across this and been able to fix it? Edit: Routing config (global.asax.vb) is: RouteTable.Routes.MapHttpRoute(name:="DefaultApi", routeTemplate:="api/{controller}/{id}", defaults:=New With {Key .id = System.Web.Http.RouteParameter.Optional}) Controller: Public Function PostValue(ByVal departmentid As Integer, ByVal emailaddress As String, ByVal firstname As String, ByVal lastname As String) As Guid Dim context As New WSMModelDataContext Dim bllPeople As New PeopleBLL(context) Return bllPeople.Create(firstname, lastname, emailaddress, departmentid) End Function When I debug it, it doesn't get as far as running the controller, although when calling it through RESTEasy it routes correctly and the controller executes successfully. The only difference seemes to be that wen called through RESTEasy it is (correctly) using http://127.0.0.1:81 but for some reason when called via JQuery/ajax it seems to be using http://127.0.0.1:82.

  • Are there existing web sites that use a photo as a electronic signature?

    - by Alessandro Vernet
    The use case: to sign a electronic document, users view the document, and if they agree take a picture of themselves with their webcam (done through Flash from the browser). Then a PDF is generated containing the document and the picture in place of signature. This is a biometric signature, which is not as strong as a digital (cryptographic) signature, but stronger than having users draw their signature, as a photo is harder to forge than a drawn signature. Has anyone seen this technique being used on an existing web site?

  • Can a client dictate whether or not HttpContext is created?

    We are getting a lot of hits from Googlebot and BingBot and it appears that none of these requests have an HttpContext. I originally thought that every http request will get a context which obviously is not the case so I'm trying to understand how does an HttpContext gets constructed, is it part of the negotiation between client and server?

  • jQuery Autocomplete losing text on AutoPostBack

    - by Moose
    I have a jQuery Autocomplete field on an ASP.Net Webform and everything has been working great until now. I also have a DropDownList that I have a need to fire onSelectedIndexChanged with AutoPostBack. When I changed my code to do the AutoPostBack, the text field that has the jQuery AutoComplete on it comes back blank. However, if I look at the source of the page, the text is in the text field. If I now post the form, the page will send back a blank field. My Google-Fu is weak on this one, as I could not come up with any workaround for it. Has anyone had any issues like this with the Autocomplete field getting blanked out on an AutoPostBack, and how did you get around it? I can post code if it's really necessary, but I'd need to sanitize a lot of it before I could due to company policy.

  • Manipulate Page Theme Programatically

    - by Aren B
    I've got the following Setup in my Theme: \App_Themes\Default\StyleSheet.css \App_Themes\Default\PrintStyleSheet.css The PrintStyleSheet.css file has a set of printing css rules set in them wrapped in an @Media Print { } block. I need a way to programmatically remove the PrintStyleSheet.css from the list of css files for ASP.NET to inject based on some flags. (Some instances we want to print the site verbatim without custom formatting). I know i could build a seperate theme without the PrintStyleSheet.css in it and switch the theme programmatically, however this would introduce duplication of my master stylesheet which is not acceptable. Any ideas?
