  • Microsoft ReportViewer Web Control Requiring a ScriptManager

    - by Maya
    I'm trying to render the report viewer programmatically within a custom Page placed in an IHttpHandler context ReportViewer rv = new ReportViewer(); ReportDataSource rds = new ReportDataSource(); rds.Name = "Report"; rv.LocalReport.ReportPath = "Report.rdlc"; rds.Value = SomeReportObject; rv.LocalReport.DataSources.Add(rds); rv.LocalReport.Refresh(); ScriptManager scriptHandler = new ScriptManager(); MyPage p = new MyPage(); p.Controls.Add(scriptHandler); p.Controls.Add(rv); using (TextWriter myTextWriter = new StringWriter()) { using (HtmlTextWriter myWriter = new HtmlTextWriter(myTextWriter)) { p.RenderControl(myWriter); } } Although I have the ScriptManager added to the page but the runtime complains that the ReportViewer needs one, it throws the following exception at p.RenderControl(myWriter) line The Report Viewer Web Control requires a System.Web.UI.ScriptManager on the web form. And this is the MyPage Class public class MyPage : Page { public override void VerifyRenderingInServerForm(Control control) { //Empty Method } public override bool EnableEventValidation { get { return false; } set { /* Do nothing */} } } Any help would be very appreciated. This is done on .NET 4 and I'm using ReportViewer 2010. Many thanks, Maya.

  • Web Service Exception Handling

    - by SchlaWiener
    I have a Winforms app that consumes a C# Webservice. If the WebService throws an Exception my Client app always get's a SoapException instead of the "real" Exception. Here's a demo: [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] public class Service1 : System.Web.Services.WebService { [WebMethod] public string HelloWorld() { throw new IndexOutOfRangeException("just a demo exception"); } } Now, on the client side, I want to be able to handle different exceptions in a different way. try { ServiceReference1.Service1SoapClient client = new ServiceReference1.Service1SoapClient(); Button1.Text = client.HelloWorld(); } catch (IndexOutOfRangeException ex) { // I know how to handle IndexOutOfRangeException // but this block is never reached } catch (MyOwnException ex) { // I know how to handle MyOwnException // but this block is never reached } catch (System.ServiceModel.FaultException ex) { // I always end in this block } But that does not work because I always get a "System.ServiceModel.FaultException" and I can only figure out the "real" exception by parsing the Exception's message property: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.IndexOutOfRangeException: just a demo\n at SoapExceptionTest.Service1.Service1.HelloWorld() in ... --- End of inner exception stack trace --- Is there a way to make this work somehow?

  • Problem when trying to configure enterprise library 5.0 (Data Access Application Block)

    - by Phil
    Hi There Stackoverflow, I am running into some problems while trying to get DAAB from Enterprise library 5.0 running. I have followed the steps as per the tutorial, but am getting errors... 1) Download / install enterprise library 2) Add references to the blocks I need (common / data) 3) Imports Imports Microsoft.Practices.EnterpriseLibrary.Common Imports Microsoft.Practices.EnterpriseLibrary.Data 4) Through the enterprise library config software. I open up the web.config from my site. I then click Blocks, then Add data settings... fill in my details and save / close 5) I then (thinking setup is complete) try to get an instance of the database via Dim db As Database = DatabaseFactory.CreateDatabase() 6) I compile and receive the following error: Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) (C:\site\web.config line 4) Line 4 off my web.config was generated by the config tool and is: <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" /> Am I missing a required step? Have I done the steps in the wrong order? Have I made a mistake? Thanks a lot for the assistance.

  • SharePoint custom web service consumption problems - HTTP 401: Unauthorized

    - by alekz
    I have a custom web service deployed into WSS 3. It has two web methods. The first one returns the version of the loaded assembly without any invocation of the SharePoint objects. The second returns some basic info about the library, something like: var spLibrary = [find library logic]; return spLibrary.Name+"@"+spLibrary.Url; In the client app I have something like the following: var service = new WebService1(); service.Url = [url]; service.Credentials = System.Net.CredentialCache.DefaultCredentials; service.Method1(); service.Method2(); When the client app runs on the machine where SharePoint is deployed, everything works just fine. When the client app runs on the remote machine (but under the same user) the first method still works, but the second one throws System.Net.WebException: HTTP 401: Unauthorized. I have tried to set credentials manualy (service.Credentials = new System.Net.NetworkCredential(login, password, domain);) but this doesnt help. I've tried to invoke the built in SharePoint web services using a similar scenario, and they work just fine: Sorry for the mistake... Some methods were not working fine without the appropriate privileges. var service = new GroupsService(); service.Url = [url]; service.Credentials = System.Net.CredentialCache.DefaultCredentials; service.SomeMethod();

  • Enable DOM Access for Silverlight Web Part in Sharepoint 2010

    - by Bhaskar
    I am hosting a silverlight 3.0 control on my Sharepoint 2010 page. I am using the built-in SilverlightWebPart web part, where I have provided the path for .xap file. Its displaying properly, but when I try to access the System.Windows.Browser, its throwing an error. My code is: public static string GetQueryString(string key) { try { var documentQueryString = (Dictionary<string, string>)System.Windows.Browser.HtmlPage.Document.QueryString; if (documentQueryString.ContainsKey(key)) { return documentQueryString[key].ToString(); } } catch (Exception ex) { return ex.Message; } return string.Empty; } The error I am getting is: The DOM/scripting bridge is disabled. How do I enable this? I know if I host this in a ASP.NET page, I can add the param - <param name="enablehtmlaccess" value="true"/>. I have tried putting this webpart in a "content editor web part", and I have embedded the object tag to call the .xap file and its working totally fine. I need to make it work using the built-in Silverlight web part.

  • HttpUtility does not exist in the current context

    - by Shaihi
    I get this error when compiling a C# application. Looks like a trivial error, but I can't get around it. My setup is Windows 7 64 bit. Visual-Studio 2010 C# express B2Rel. I added a reference to System.Web.dll located at C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0, but it has a yellow exclamation symbol and I still get the above error. I also have the using System.Web declaration. What am I doing wrong? Update: After getting the prompt answer pointing me at the root cause, I searched a bit in Google to where it states that System.Web.dll is for the full framework. I did not find such a reference. For newbies like me, this blog summarizes the difference between the frameworks (client and full) nicely. I could not find a spot that says whether a certain Dll is supported in the client framework or not. I guess the exclamation mark in Visual Studio should be the first signal...

  • Configuration Error ASP.NET password format specified is invalid

    - by salvationishere
    I am getting the above error in IIS 6.0 now when I browse my C# / SQL web application. This was built in VS 2008 and SS 2008 on a 32-bit XP OS.

  • Getting web page after calling DownloadStringAsync()?

    - by OverTheRainbow
    Hello I don't know enough about VB.Net yet to use the richer HttpWebRequest class, so I figured I'd use the simpler WebClient class to download web pages asynchronously (to avoid freezing the UI). However, how can the asynchronous event handler actually return the web page to the calling routine? Imports System.Net Public Class Form1 Private Shared Sub DownloadStringCallback2(ByVal sender As Object, ByVal e As DownloadStringCompletedEventArgs) If e.Cancelled = False AndAlso e.Error Is Nothing Then Dim textString As String = CStr(e.Result) 'HERE : How to return textString to the calling routine? End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim client As WebClient = New WebClient() AddHandler client.DownloadStringCompleted, AddressOf DownloadStringCallback2 Dim uri As Uri = New Uri("http://www.google.com") client.DownloadStringAsync(uri) 'HERE : how to get web page back from callback function? End Sub End Class Thank you. Edit: I added a global, shared variable and a While/DoEvents/EndWhile, but there's got to be a cleaner way to do this :-/ Public Class Form1 Shared page As String Public Shared Sub AlertStringDownloaded(ByVal sender As Object, ByVal e As DownloadStringCompletedEventArgs) ' If the string request went as planned and wasn't cancelled: If e.Cancelled = False AndAlso e.Error Is Nothing Then page = CStr(e.Result) End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim wc As New WebClient AddHandler wc.DownloadStringCompleted, AddressOf AlertStringDownloaded page = Nothing wc.DownloadStringAsync(New Uri("http://www.google.com")) 'Better way to wait until page has been filled? While page Is Nothing Application.DoEvents() End While RichTextBox1.Text = page End Sub End Class

  • nHibernate strategies in a web farm

    - by Pete Nelson
    Our current project at work is a new MVC web site that will use a WCF service primarily to access a 3rd party billing system via a web service as well as a small SQL database for user personalization. The WCF service uses nHibernate for the SQL database. We'd like to implement some sort of web farm for load balancing as well as failover and maintenance. I'm trying to decide the best way to handle nHibernate's caching and database concurrency if there are multiple WCF services running. Some scenarios I've been thinking about... 1) Multiple IIS servers, one WCF server. With this setup, the WCF server would be a single point of failure, but there would be no issues with nHibernate caching or database concurrency. 2) Multiple IIS servers, each with it's own WCF service. This removes a single point of failure, but now nHibernate on one machine would not know about database changes done by another machine. Some solutions to number 2 would be to use an IStatelessSession so we're not doing any caching and nHibernate is always fetching directly from the database. This might be the most feasible as our personalization database has very few objects in it. I'm also considering a 2nd-level cache such as memcached or Velocity, but it may be overkill for this system. I'm putting this out there to see if anyone has experience doing this sort of architecture and to get some ideas for a solution. Thanks!

  • Setting up a "cookieless domain" to improve site performance

    - by Django Reinhardt
    I was reading in Google's documentation about improving site speed. One of their recommendations is serving static content (images, css, js, etc.) from a "cookieless domain": Static content, such as images, JS and CSS files, don't need to be accompanied by cookies, as there is no user interaction with these resources. You can decrease request latency by serving static resources from a domain that doesn't serve cookies. Google then says that the best way to do this is to buy a new domain and set it to point to your current one: To reserve a cookieless domain for serving static content, register a new domain name and configure your DNS database with a CNAME record that points the new domain to your existing domain A record. Configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain. In your web pages, reference the domain name in the URLs for the static resources. This is pretty straight forward stuff, except for the bit where it says to "configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain". From what I've read, there's no setting in IIS that allows you to say "serve static resources", so how do I prevent ASP.NET from setting cookies on this new domain? At present, even if I'm just requesting a .jpg from the new domain, it sets a cookie on my browser, even though our application's cookies are set to our old domain. For example, ASP.NET sets an ".ASPXANONYMOUS" cookie that (as far as I'm aware) we're not telling it to do. Apologies if this is a real newb question, I'm new at this! Thanks.

  • This 404 seems unavoidable - what am I doing wrong? [Ninject 2.0 with ASP.NET MVC 2 on .NET 4]

    - by Tomas Lycken
    I downloaded the fairly new Ninject 2.0 and Ninject.Web.Mvc (targeting mvc2) sources today, and successfully built them against .NET 4 (release configuration). When trying to run an application using Ninject 2.0, i keep getting 404 errors and I can't figure out why. This is my global.asax.cs (slightly shortified, for brevity): using ... using Ninject; using Ninject.Web.Mvc; using Ninject.Modules; namespace Booking.Web { public class MvcApplication : NinjectHttpApplication { protected override void OnApplicationStarted() { Booking.Models.AutoMapperBootstrapper.Initialize(); RegisterAllControllersIn(Assembly.GetExecutingAssembly()); base.OnApplicationStarted(); } protected void RegisterRoutes(RouteCollection routes) { ... routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Entry", action = "Index", id = "" } ); } protected override IKernel CreateKernel() { INinjectModule[] mods = new INinjectModule[] {...}; return new StandardKernel(mods); } } } The EntryController exists, and has an Index method that simply does a return View(). I have debugged, and verified that the call to RegisterAllControllersIn() is executed. I have also tried to use Phil Haacks Routing debugger but I still get a 404. What do I do to find the cause of this?

    Using GoDaddy to host my site (I know that's my first problem)! :-) Trying to setup customer error messages for my site using IIS7.

  • Wysiwyg with image copy/paste

    - by jW
    First, I understand that an image cannot be "copied" from a local machine into a website. I understand that it must be uploaded. I am a web programmer, and am familiar with common web wysiwyg tools such as TinyMCE and FCKEditor. My question is if there exists a program or web module or something of the sort that works will perform an automatic upload of images for a wysiwyg. I have a client that is constantly complaining about not being able to copy/paste documents with images from MS Word into a wysiwyg to create content on their website. I have looked into TX Text Control (http://labs.textcontrol.com/) and was looking into a possibly flash wysiwyg that could upload the file automatically behind the scenes. I don't know if this exists, and google did not much help me in my search, so I thought I would ask other coders. I am open to any sort of server technology, or browser requirements. I am looking for some browser based tool instead of an application tool such as Dreamweaver or otherwise. If no good solution to the problem exists, I am willing to accept that at this point. Note: This was a request from a client, and to me it seemed rather unreasonable. I decided to gather community advice instead of just tell the client 'No' and the options here have been extremely helpful and informative in presenting possible solutions.

  • Python web scraping involving HTML tags with attributes

    - by rohanbk
    I'm trying to make a web scraper that will parse a web-page of publications and extract the authors. The skeletal structure of the web-page is the following: <html> <body> <div id="container"> <div id="contents"> <table> <tbody> <tr> <td class="author">####I want whatever is located here ###</td> </tr> </tbody> </table> </div> </div> </body> </html> I've been trying to use BeautifulSoup and lxml thus far to accomplish this task, but I'm not sure how to handle the two div tags and td tag because they have attributes. In addition to this, I'm not sure whether I should rely more on BeautifulSoup or lxml or a combination of both. What should I do? At the moment, my code looks like what is below: import re import urllib2,sys import lxml from lxml import etree from lxml.html.soupparser import fromstring from lxml.etree import tostring from lxml.cssselect import CSSSelector from BeautifulSoup import BeautifulSoup, NavigableString address='http://www.example.com/' html = urllib2.urlopen(address).read() soup = BeautifulSoup(html) html=soup.prettify() html=html.replace('&nbsp', '&#160') html=html.replace('&iacute','&#237') root=fromstring(html) I realize that a lot of the import statements may be redundant, but I just copied whatever I currently had in more source file. EDIT: I suppose that I didn't make this quite clear, but I have multiple tags in page that I want to scrape.

  • Asp.net Crawler Webresponse Operation Timed out.

    - by Leon
    Hi I have built a simple threadpool based web crawler within my web application. Its job is to crawl its own application space and build a Lucene index of every valid web page and their meta content. Here's the problem. When I run the crawler from a debug server instance of Visual Studio Express, and provide the starting instance as the IIS url, it works fine. However, when I do not provide the IIS instance and it takes its own url to start the crawl process(ie. crawling its own domain space), I get hit by operation timed out exception on the Webresponse statement. Could someone please guide me into what I should or should not be doing here? Here is my code for fetching the page. It is executed in the multithreaded environment. private static string GetWebText(string url) { string htmlText = ""; HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url); request.UserAgent = "My Crawler"; using (WebResponse response = request.GetResponse()) { using (Stream stream = response.GetResponseStream()) { using (StreamReader reader = new StreamReader(stream)) { htmlText = reader.ReadToEnd(); } } } return htmlText; } And the following is my stacktrace: at System.Net.HttpWebRequest.GetResponse() at CSharpCrawler.Crawler.GetWebText(String url) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 366 at CSharpCrawler.Crawler.CrawlPage(String url, List1 threadCityList) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 105 at CSharpCrawler.Crawler.CrawlSiteBuildIndex(String hostUrl, String urlToBeginSearchFrom, List1 threadCityList) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 89 at crawler_Default.threadedCrawlSiteBuildIndex(Object threadedCrawlerObj) in c:\myAppDev\myApp\site\crawler\Default.aspx.cs:line 108 at System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object state) at System.Threading.ExecutionContext.runTryCode(Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem() at System.Threading.ThreadPoolWorkQueue.Dispatch() at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback() Thanks and cheers, Leon.

  • Explaining the need to avoid horizontal scroll

    - by Bradley Herman
    I need help explaining to my boss why her design is poor on a client's website. She has no knowledge of the web, and it can be difficult as a web developer working with a woman who is a graphic designer (not even a web designer really). On a current site she has designed, an image bar "needs" to be ~1200px according to her, though it isn't necessary with the content. A quick sketch to illustrate what's going on: As you see, the banner spills out past the 960px of the content and as wide as 1200px. This creates a horizontal scroll when all the content is viewable within the 960px wide viewport. I need to make this an <img and not a CSS background because it's a jQuery slideshow that fades from image to image. I think this is a big problem because a lot of people are going to get a horizontal scroll bar imposed in their browser when they're still able to see all the relevant content. She thinks no one will notice and it'll be fine; I think it's very bad practice and confusing to the end user. How do I explain the problem to her?

  • Handling 'session expired' in JSF web application, running in JBoss AS 5

    - by Veera
    This question is related to my other question "How to redirect to Login page when Session is expired in Java web application?". Below is what I'm trying to do: I've a JSF web application running on JBoss AS 5 When the user is inactive for, say 15 minutes, I need to log out the user and redirect him to the login page, if he is trying to use the application after the session has expired. So, as suggested in 'JSF Logout and Redirect', I've implemented a filter which checks for the session expired condition and redirects the user to a session-timed-out.jsp page, if the session has expired. I've added SessionExpiryCheckFilter on top of all other filter definitions in web.xml, so that my session expiry check will get the first hit always. Now comes the challenge I'm facing. Since I'm using JBoss AS, when the session expired, JBoss automatically redirects me to the login page (note that the session expiry check filter is not invoked). So, after I log-in, my SessionExpiryCheckFilter intercepts the request, and it sees a session is available. But, it throws the exception javax.faces.application.ViewExpiredException: viewId:/mypage.faces - View /mypage.faces could not be restored. Have anyone faced this issue before? Any ideas to solve this issue?

    Hi, I'm trying to build a "visual web part" for SharePoint 2010 which should connect to Oracle table and display records on SharePoint page.For development, Oracle 11g client (with ODP.net) ,SharePoint server 2010, Visual Studio 2010 and Oracle 10g express all running on my machine. First,I've written sample code in ASP.NET web app to connect my local Oracle table and display data in grid view and it works fine. My code is , OracleConnection con; try { // Connect string constr = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));User Id=SYSTEM; Password=password"; con = new OracleConnection(constr); //Open database connection con.Open(); // Execute a SQL SELECT OracleCommand cmd = new OracleCommand("select * from T_ACTIONPOINTS WHERE AP_STATUS='Active' ", con); OracleDataReader dr = cmd.ExecuteReader(); GridView.DataSource = dr; GridView.DataBind(); GridView.AllowPaging = true; } catch (Exception e) { lblError.Text = e.Message; } Now, I'm trying to create new "SharePoint" visual web part project and using same code and deploying it on my local SP server. But when it runs , I get following error here is my solution explorer, It looks something wrong in compatibility.Can someone point me in right direction ?

  • What is your preferred tool stack for PHP development in the Windows Environment?

    - by Tim Visher
    I have been developing basic web sites for awhile now with some PHP thrown in for getting dynamic stuff done. However, I recently decided that it was time I got my hands a little dirtier so I wanted to start to play with the underpinnings of Wordpress and other such apps. I work on a Mac at home and have been using Coda for most of my editing needs and I love it. Also, to manage the services stack I use MAMP at home. However, I've begun to realize that for heavy PHP and Web work (AJAX, etc.), more is needed. I'm very interested to hear the kinds of tools more experienced web developers use on a day to day basis to manage the entire work flow. I found this article over on developer tutorials and decided to go with XAMPP (for the moment) for managing the services. However, IDE, Source Control, Debugger, etc. are all up for grabs. Anyway, your thoughts are much appreciated. And, if at all possible, try to describe your entire stack with what each tool fulfills for your development process.

  • 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?

  • Google Web Toolkit Asynchronous Call from a Service Implementation

    - by Thor Thurn
    I'm writing a simple Google Web Toolkit service which acts as a proxy, which will basically exist to allow the client to make a POST to a different server. The client essentially uses this service to request an HTTP call. The service has only one asynchronous method call, called ajax(), which should just forward the server response. My code for implementing the call looks like this: class ProxyServiceImpl extends RemoteServiceServlet implements ProxyService { @Override public Response ajax(String data) { RequestBuilder rb = /*make a request builder*/ RequestCallback rc = new RequestCallback() { @Override public void onResponseReceived(Response response) { /* Forward this response back to the client as the return value of the ajax method... somehow... */ } }; rb.sendRequest(data, requestCallback); return /* The response above... except I can't */; } } You can see the basic form of my problem, of course. The ajax() method is used asynchronously, but GWT decides to be smart and hide that from the dumb old developer, so they can just write normal Java code without callbacks. GWT services basically just do magic instead of accepting a callback parameter. The trouble arises, then, because GWT is hiding the callback object from me. I'm trying to make my own asynchronous call from the service implementation, but I can't, because GWT services assume that you behave synchronously in service implementations. How can I work around this and make an asynchronous call from my service method implementation?
