  • asp.net webservice user management across pages

    - by nakori
    I'm developing a site that will display confidential readonly information, with data fetched from a WCF service. My question: What is the best approach to user management across different information pages. The service returns a collection with customer info after a secure login. My idea is to have a Customer object class that is stored in session. Is it possible to use things like HttpContext.Current.User.Identity.IsAuthenticated followed by HttpContext.Current.Session["UserId"] without using a database with role-based security? Would I be better off with a combination of local database, Linq to SQL or datasets rather than using just class objects for data fetched from service? thanks, nakori

  • Windows SQL wildcards and ASP.net parameters

    - by Vinzcent
    Hey In my SQL statement I use wildcards. But when I try to select something, it never select something. While when I execute the querry in Microsoft SQL Studio, it works fine. What am I doing wrong? Click handler protected void btnTitelAuteur_Click(object sender, EventArgs e) { cvalTitelAuteur.Enabled = true; cvalTitelAuteur.Validate(); if (Page.IsValid) { objdsSelectedBooks.SelectMethod = "getBooksByTitleAuthor"; objdsSelectedBooks.SelectParameters.Clear(); objdsSelectedBooks.SelectParameters.Add(new Parameter("title", DbType.String)); objdsSelectedBooks.SelectParameters.Add(new Parameter("author", DbType.String)); objdsSelectedBooks.Select(); gvSelectedBooks.DataBind(); pnlZoeken.Visible = false; pnlKiezen.Visible = true; } } In my Data Acces Layer public static DataTable getBooksByTitleAuthor(string title, string author) { string sql = "SELECT 'AUTHOR' = tblAuthors.FIRSTNAME + ' ' + tblAuthors.LASTNAME, tblBooks.*, tblGenres.GENRE " + "FROM tblAuthors INNER JOIN tblBooks ON tblAuthors.AUTHOR_ID = tblBooks.AUTHOR_ID INNER JOIN tblGenres ON tblBooks.GENRE_ID = tblGenres.GENRE_ID " +"WHERE (tblBooks.TITLE LIKE '%@title%');"; SqlDataAdapter da = new SqlDataAdapter(sql, GetConnectionString()); da.SelectCommand.Parameters.Add("@title", SqlDbType.Text); da.SelectCommand.Parameters["@title"].Value = title; DataSet ds = new DataSet(); da.Fill(ds, "Books"); return ds.Tables["Books"]; } Thanks, Vincent

  • Using ASP.NET Redirect without string URL?

    - by David Dietrich
    For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

  • Core dump utility for .NET

    - by Dave
    In my past life as a COBOL mainframe developer I made extensive use of a tool called Abendaid which, in the event of an exception, would give me a complete memory dump including a formatted list of every variable in memory as well as a complete stack trace of the program with the offending statement highlighted. This made pinpointing the cause of an error much simpler and saved a lot of step-through debugging and/or trace statements. Now I've made the transition to C# and .NET web development I find that the information provided by ASP.NET only tells half the story, giving me a stack trace, but not any of the variable or class information. This makes debugging more difficult as you then have to run the process again with the debugger to try and reproduce the error, not easy with intermittent errors or with assemblies that run under the likes of SQL Server or CRM. I've looked around quite a lot for something that does this but I can't find anything obvious. Does anyone have any idea if there is one, or if not, what I'd need to start with in order to write one?

  • Resizing Images with ASP.NET and saving to Database

    - by Ryan
    I need to take an uploaded image, resize it, and save it to the database. Simple enough, except I don't have access to save any temp files to the server. I'm taking the image, resizing it as a Bitmap, and need to save it to a database field as the original image type (JPG for example). How can I get the FileBytes() like this, so I can save it to the database? Before I was using ImageUpload.FileBytes() but now that I'm resizing I'm dealing with Images and Bitmaps instead of FileUploads and can't seem find anything that will give me the bytes. Thanks!

  • ASP.net SessionState Error in Design Mode

    - by stringo0
    I'm getting a weird error in the design view for a user creation page for 2 controls: Error Creating Control - wCreateUser Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. (There's some more) I've done both of these, but I'm still getting the error in design mode. The controls work fine when compiled, and on the live site - this is just in the Visual Web Developer 2010 Design view for the page. Any ideas as to how I can resolve this? Thanks!

  • ASP.NET handling button click event before OnPreInit

    - by Phillykins
    Hello, I have a data access layer, a business logic layer and a presentation layer (ie. the pages themselves). I handle the OnPreInit event and populate collections required for the page. All the data comes from an SQL server database and I do not use caching. I handle a button click event to grab values from a form and insert a new object into the database. The problem is that by the time I handle the click event, the collections have already been populated, so the new item which has been inserted into the database has not been retrieved. What is the accepted solution to this? I could insert the new object directly into the collection and re-bind the GridView, but the SQL query selects only a set of objects and the new object could fall outside of this set. Thanks!

  • javascript equivalent of ASP preInit event

    - by Pankaj Kumar
    Hi guys, searching for this has yielded no resuts.. i have a middle page that has an iframe and all the pages open in that iframe...i have to implement a chat system just like in Google and so to ensure that the chat windows did not close whwn the page would postback i am opening all pages in iframe.... this is a social networking site and user can have themes which have background images per theme now when i visit a friends profile the backgrounf image of the middle page should change... i have this code to find parent of iframe and change background image $(document).ready(function(){ var theme=document.getElementById("ctl00_decideFooterH").value; var t= parent.document.getElementsByTagName("body"); if(theme=='basicTheme'){ t[0].className="basic"; } else if(theme=='Tranquility') { t[0].className="Tranquility"; } else if(theme=='AbstractPink') { t[0].className="abstractPink"; } }); and this code is the master page that all child pages that would open in iframe would access..the trouble is that there is a lag between the theme application on server side(which happens at PreInit) and the background image change which is done by this document.ready that gets executed after the iframe has loaded.. so essentially i need a javascript function that would either execute parallel to PreInit or some other logic....so guys plz help its urgent

  • What is the way to go to fake my database layer in a unit test?

    - by Michel
    Hi, i have a question about unit testing. say i have a controller with one create method which puts a new customer in the database: //code a bit shortened public actionresult Create(Formcollection formcollection){ client c = nwe client(); c.Name = formcollection["name"]; ClientService.Save(c); { Clientservice would call a datalayer object and save it in the database. What i do now is create a database testscript and set my database in a know condition before testing. So when i test this method in the unit test, i know that there must be one more client in the database, and what it's name is. In short: ClientController cc = new ClientController(); cc.Create(new FormCollection (){name="John"}); //i know i had 10 clients before assert.areEqual(11, ClientService.GetNumberOfClients()); //the last inserted one is John assert.areEqual("John", ClientService.GetAllClients()[10].Name); So i've read that unit testing should not be hitting the database, i've setup an IOC for the database classes, but then what? I can create a fake database class, and make it do nothing. But then ofcourse my assertions will not work because if i say GetNumberOfClients() it will alwasy return X because it has no interaction with the fake database class used in the Create Method. I can also create a List of Clients in the fake database class, but as there will be two different instance created (one in the controller action and one in the unit test), they will have no interaction. What is the way to make this unit test work without a database?

  • How to make a Generic Repository?

    - by chobo2
    Hi I am wondering if anyone has any good tutorials(or maybe even a library that is already made and well documented) on making a generic repository. I am using currently linq to sql but it might change so I don't know if you can make a generic repository that would take little to no changes if I would say switch to entity framework. Thanks

  • C# ASP.Net The type or namespace name 'iAnywhere' could not be found

    - by Louis Russell
    Morning all, I know that this sounds like a simple referencing problem from the title this is becoming a nightmare! I have a code class that uses the "iAnywhere.Data.AsaClient.dll". This Dll is referenced in the project and in the code class I have added this dll in the Using section. Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0246: The type or namespace name 'iAnywhere' could not be found (are you missing a using directive or an assembly reference?) The line that the Error points to this line in the class: using iAnywhere.Data.AsaClient; I have set the dll to copy local and it makes no difference, the Dll is installed on my PC so is in the GAC, I use this Dll with many other C# projects and have no problems. I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem. Any help would be brilliant!

  • ASP.NET catching controls from html generated from the database

    - by Drahcir
    I have a set of websites that basically do the exact same thing in terms of functionality, the only thing that varies is the css and how the html is laid out. Is there a way to generate the html from a database (ie retreiving the html from a table) and then catching the controls (like buttons, textboxes etc) from the code behind? UPDATE: Here is an example of what I want to acheive: <html> <div id="generatedContent" runat="server"> <!-- the following content has been generated from the database on the page load event --> <div> This is a textbox <input id="tb1" runat="server" type="text" /> This is a button <input type="submit" id="btn1" runat="server" value="My Button" /> </div> </div> </html> This is the code behind var tb1 = new HtmlControls.HtmlInputText(); tb1 = FindControl("tb1"); var btn1 = new New HtmlControls.HtmlInputSubmit(); btn1 = FindControl("btn1"); Now obviously since the html has been generated from the database (ie after the page has already been initialised) the FindControl method will return null.
