  • Adding OutputCache to an ASP.NET WebForm crashes my site :(

    - by Pure.Krome
    Hi folks, When I add either one of these ... <%@ OutputCache Duration="600" Location="Any" VaryByParam="*" %> or <%@ OutputCache CacheProfile="CmsArticlesListOrItem" %> (.. and this into the web.config file...) <caching> <outputCacheSettings> <outputCacheProfiles> <add name="CmsArticlesListOrItem" duration="600" varyByParam="*" /> </outputCacheProfiles> </outputCacheSettings> <sqlCacheDependency ........ ></sqlCacheDependency </caching> my page/site crashes with the following error:- Source: System.Web ---------------------------------------------------------------------------- TargetSite: System.Web.DirectoryMonitor FindDirectoryMonitor(System.String, Boolean, Boolean) ---------------------------------------------------------------------------- Message:System.Web.HttpException: Directory 'C:\Web Sites\My Site Foo - Main Site\Controls\InfoAdvice' does not exist.

Well, i've had this site live for around 3 years and i'm pretty sure that the folders \Controls and \Controls\InfoAdvice doesn't exist on my production server. On my localhost, it sure does .. and contains a large list of ascx controls. But they don't exist on my live server. So ... what is going on here? Can anyone please help? Oh :) Before someone suggests I create those two folders and even stick a random file in those folders .. and have some random text in those random files .. i've done that and it doesn't seem to work, still :( Please Help !

  • Trying to use an Xslt for an xml in asp.net

    - by Josemalive
    Hello, i have the following xslt sheet: <?xml version="1.0" encoding="UTF-8" ?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:variable name="nhits" select="Answer[@nhits]"></xsl:variable> <xsl:output method="html" indent="yes"/> <xsl:template match="/"> <div> <xsl:call-template name="resultsnumbertemplate"/> </div> </xsl:template> <xsl:template name="resultsnumbertemplate"> <xsl:value-of select="$nhits"/> matches found </xsl:template> </xsl:stylesheet> And this is the xml that im trying to mix with the previous xslt: <Answer xmlns="exa:com.exalead.search.v10" context="n%3Dsl-ocu%26q%3Dlavadoras" last="9" estimated="false" nmatches="219" nslices="0" nhits="219" start="0"> <time> <Time interrupted="false" overall="32348" parse="0" spell="0" exec="1241" synthesis="15302" cats="14061" kwds="14061"> <sliceTimes>15272 </sliceTimes> </Time> </time> </Answer> Im using a xslcompiledtransform and that's working fine: XslCompiledTransform transformer = new XslCompiledTransform(); transformer.Load(HttpContext.Current.Server.MapPath("xslt\\" + requestvariables["xslsheet"].ToString())); transformer.Transform(xmlreader, null, writer); My problems comes when im trying to put into a variable the "nhits" attribute value placed on the Answer element, but i'm not rendering anything using my xslt sheet. Do you know what could be the cause? Could be the xmlns attribute in my xml file? Thanks in advance. Best Regards. Jose

  • SharePoint 2010 / ASP.Net Integration - Looking for advice

    - by jpennal
    I have been Googling a problem that I have with trying to integrate the web application that I am working on with SharePoint 2010. The web application is a wiki style tool that allows users to log in via forms authentication or WIA against Active Directory and create content for themselves and others. What we would like to do is to allow a user have a page with the content they have created in our web application mixed in with content that they have living on the SharePoint server. For example, they may want to see a list of documents that they have on the SharePoint server mixed in with some of their content. To accomplish this, we would like to take the credentials the user has logged into our web application with (for example MYDOMAIN\jsmith) and be able to query SharePoint for the documents of that same user (MYDOMAIN\jsmith) WITHOUT the user being prompted to re-enter their credentials to access the SharePoint server (we are trying to avoid the double-hop problem) We have come up with some options for how we want to do this, but we are unsure of what the best approach is. For example, we could - Have a global user, shared by all users to get information we need from SharePoint. The downside is that we cannot filter SharePoint content to a particular user - We could store the users credentials when they log in, but that would only work for users authenticating via forms auth and would be a security issue that some users/clients would not like - Writing a SharePoint extension using WCF to allow us to access the information we need, however we'd still have the issue of figuring out how to impersonate the user we want. Neither of these options are ideal and in our investigation we came across the Claims Authentication/STS option which seems like it is trying to solve the problem we are having. So my question is, based on what I have written, is Claims/STS the best approach for us? We have not been able to find much direction on how to use this method to call into SharePoint from a Web Application and pass along the existing credentials. Does anyone have any experience with any of these issues?

  • ASP.NET - Display Message While Page Is Loading

    - by Chris
    I have a page that performs a long-running task (10 to 15 seconds) in the page_load method. I have client-side javascript code that will display a decent "page loading" animated gif to the user. I am able to invoke the JavaScript method from the code-behind, to display the "page loading" animated gif, however, the long-running task is hanging up the UI such that the animated gif doesn't actually display until after the long-running task is complete, which is the exact opposite of what I want. To test this out, in my page_load method I make a call to the JavaScript method to display the animated gif. Then, I use Thread.Sleep(10000). What happens is that the animated gif doesn't display until after Thread.Sleep is complete. Obviously I am doing something incorrect. Any advice would be appreciated. Thanks. Chris

  • outputting html in runtime in asp.net

    - by madness800
    Hi all, I'm building a website at the moment, I've some html fragment that is being stored into the database, I've been reading around that inserting HTML at runtime poses security risks by using the InnerHTML property of any html tag with runat server on it. So, my question is there any alternative way to safely display the html code and won't pose security risks and is it best to assume any textboxes on any given page is dangerous and process the text in the textboxes with Server.HtmlEncode before I store it to database? Cheers

  • retain drop down value page posting back to itself asp.net

    - by d3020
    I have an aspx page that has... if (!IsPostBack) { PopulateBrand(); in the Page_Load. This PopulateBrand() simply populates my drop down. That works great and on post back it retains the value. The problem I'm having is that there is also a link on the page that is posting back some parameters to this page. What is happening is that when this is clicked it's falling through this !IsPostBack section and wiping out my drop down values that I had selected and repopulating it. How can I prevent this and just retain what I selected when this page is posting back to itself when the link is clicked? Thanks.

  • Validation with State Pattern for Multi-Page Forms in ASP.NET

    - by philrabin
    I'm trying to implement the state pattern for a multi-page registration form. The data on each page will be accumulated and stored in a session object. Should validation (including service layer calls to the DB) occur on the page level or inside each state class? In other words, should the concrete implementation of IState be concerned with the validation or should it be given a fully populated and valid object? See "EmptyFormState" class below: namespace Example { public class Registrar { private readonly IState formEmptyState; private readonly IState baseInformationComplete; public RegistrarSessionData RegistrarSessionData { get; set;} public Registrar() { RegistrarSessionData = new RegistrarSessionData(); formEmptyState = new EmptyFormState(this); baseInformationComplete = new BasicInfoCompleteState(this); State = formEmptyState; } public IState State { get; set; } public void SubmitData(RegistrarSessionData data) { State.SubmitData(data); } public void ProceedToNextStep() { State.ProceedToNextStep(); } } //actual data stored in the session //to be populated by page public class RegistrarSessionData { public string FirstName { get; set; } public string LastName { get; set; } //will include values of all 4 forms } //State Interface public interface IState { void SubmitData(RegistrarSessionData data); void ProceedToNextStep(); } //Concrete implementation of IState //Beginning state - no data public class EmptyFormState : IState { private readonly Registrar registrar; public EmptyFormState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //Should Validation occur here? //Should each state object contain a validation class? (IValidator ?) //Should this throw an exception? } public void ProceedToNextStep() { registrar.State = new BasicInfoCompleteState(registrar); } } //Next step, will have 4 in total public class BasicInfoCompleteState : IState { private readonly Registrar registrar; public BasicInfoCompleteState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //etc } public void ProceedToNextStep() { //etc } } }

  • ASP.Net AJAX controls, adding via .ashx page

    - by Matt Dawdy
    Okay, this is a continuation of a previous question of mine, but it is distinct enough to be its own question. Based on user interaction, I'm calling a .ashx handler via a jquery ajax call, and that handler is building some html for me that includes some Telerik controls like a masked textbox (masked for a phone number like "(###) ###-####". I got around all the hurdles of using Render() to get the html output of a server control even when it doesn't have a "Page" object or a ScriptHandler object. However, when I show the control to a user, I see the mask in the text of the textbox, but the mask doesn't "work" in the sense that when a user starts typing, it is as if the mask is really just text. So, my question is, after putting the html code out for a masked textbox, how do I tell whatever javascript is supposed to mask the input to really start masking on that specific control? I really hope this made sense. Please tell me if you need any clarification.

  • ASP.NET - Overriding Gridview OnRowCreated to add sort images -- columns are null

    - by Zach
    I'm overriding the onrowcreated to add sort images to the header row of a gridview. This works, but actually adding a sortexpression doesn't. What I want to do is set the images as imagebuttons and set their commandarguments to the sort expression of the column they are sorting for. I would assume I could get the cell and from it's index get the gridviewcolumn. Then, I could just get the sortexpression of the gridview column, but this does not work. The columns are null. OnRowCreated Code snippet below: //if this is the header row, we add sort images to each cell if (row.RowType == DataControlRowType.Header) { //iterate through the cells for (int i = 0; i < row.Cells.Count; i++) { //if the column is sortable and visible if (this.Columns[i].SortExpression != string.Empty && this.Columns[i].Visible) { string strSort = this.Columns[i].SortExpression; } } } Can we not get columns in OnRowCreated like this?

  • ASP.Net HttpModule List<> content

    - by test
    We have created an http module that loads data on initialize into a list, and uses that list on every endrequest event of application. However we got a null reference exception on the module at endRequest event complaining that the content is null. Yet we are sure that at module initialization we have put non-null objects correctly. How is this possible? Any ideas? Thanks in advance. The place where i fill the data into the list what named as "Pages" : using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { LandingPageDetails details = new LandingPageDetails(); details.DomainId = Convert.ToInt32(reader["DomainId"]); details.PageId = Convert.ToInt32(reader["TrackingPageId"]); details.PageAddress = Convert.ToString(reader["PageAddress"]); if (!string.IsNullOrEmpty(details.PageAddress)) { Pages.Add(details); } } } // Find the related record on EndRequesst event LandingPageDetails result = Pages.Find ( delegate(LandingPageDetails current) { return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); } ); The line what we get the error return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); "current" is the null object P.S : It works properly, but one day later contents become null. Possibly, there is something wrong on IIS. Our server is Windows 2003, IIS 6.0

  • ASP.NET Download All Files as Zip

    - by Ronnie Overby
    I have a folder on my web server that has hundreds of mp3 files in it. I would like to provide the option for a user to download a zipped archive of every mp3 in the directory from a web page. I want to compress the files programmatically only when needed. Because the zip file will be quite large, I am thinking that I will need to send the zip file to the response stream as it is being zipped, for performance reasons. Is this possible? How can I do it?

  • Issue Querying LDAP DirectoryEntry in ASP.NET

    - by davemackey
    I have users login to my application via Active Directory and then pull from their AD information to garner information about that user like so: Dim ID as FormsIdentity = DirectCast(User.Identity, FormsIdentity) Dim ticket as FormsAuthenticationTicket = ID.Ticket Dim adDirectory as New DirectoryEntry("LDAP://DC=my,DC=domain,DC=com") Dim adTicketID as String = ticket.Name.Substring(0, 5) Session("people_id") = adDirectory.Children.Find("CN=" & adTicketID).Properties("employeeID").Value Session("person_name") = adDirectory.Children.Find("CN=" & adTicketID).Properties("displayName").Value Now, I want to be able to impersonate other users...so that I can "test" the application as them, so I added a textbox and a button to the page and when the button is clicked the text is assigned to a session variable like so: Session("impersonate_user") = TextBox1.Text When the page reloads I check to see if Session("impersonate_user") has a value other than "" and then attempt to query Active Directory using this session variable like so: If CStr(Session("impersonate_user")) <> "" Then Dim adDirectory as New DirectoryEntry(LDAP://DC=my,DC=domain,DC=com") Dim adTicketID as String = CStr(Session("impersonate_user")) Session("people_id") = adDirectory.Children.Find("CN=" & adTicketID).Properties("employeeID").Value Session("person_name")= adDirectory.Children.Find("CN=" & adTicketID).Properties("displayName").Value Else [use the actual ticket.name to get this info.] End If But this doesn't work. Instead, it throws an error on the first Session line stating, "DirectoryServicesCOMException was unhandled by user code There is no such object on the server." Why? I know I'm giving it a valid username! Is something strange happening in the casting of the session? The code is essentially the same between each method except that in one method rather than pulling from ticket.Name I pull from a session variable for the login I'll be looking up with AD.

  • ASP.net - Crystal Reports exporting to PDF adds the letter "i" to certain words randomly

    We are using Crystal Reports to generate pdf's of customer bills (from a CR template). It works fine except the engine seems to be adding the letter "i" to random words in the output. Certain alignment problems are also evident (words overlapping etc). Standard fonts are being used. We are using .net 4 and C# linked to the 10.5 CR assemblies. Latest version of Adobe Acrobat reader is installed on the server. We have now tried this via 12.2 CR assemblies with the same results. We have also tried multiple .rpt files with the same results.

  • Updating a DLL in a Production ASP.NET Web Site bin folder

    - by Josh Stodola
    I want to update a class library (a single DLL file) in a production web application. This web app is pre-compiled (published). I read an answer on StackOverflow (sorry, can't seem to find it anymore because the Search function does not work very well), that led me to believe that I could just paste the new DLL in the bin folder and it would be picked up without problems (this would cause the WP to recycle, which is fine with me because we do not use InProc session state). However, when I tried this, my site blows up and gives a FileLoadException saying that the assembly manifest definition does not match the assembly reference. What in the world is this?! Updating the DLL in Visual Studio and re-deploying the entire site works just fine, but it is a huge pain in the rear. What is the point of having a separate DLL if you have to re-deploy the entire site to implement any changes? Here's the question: How can I update a DLL on a production web site without breaking the app and without re-deploying all of the files?
