  • ASP.NET HTTPHandler

    - by josephj1989
    I have an HttpHandler class (implements IHttphandler) where the path defined for the handler in web.config is *.jpg. I am requesting a Jpg image in my page. Within the HTTP Handler I am writing to a file in the filesystem. By mistake I was trying to write to a non existant directory. This should have thrown an exception but the execution simply proceeds.Ofcourse no file is writte. But if I give a proper directory the file is written correctly.Is there anything special about HttpHandler Exceptions. See part of the code public void ProcessRequest(HttpContext context){ File.WriteAllLines(context.Request.ApplicationPath+@"\"+"resul.log",new string[]{"Entered JPG Handler"});

  • Asp.net Response.Redirect Error

    - by andrewWinn
    My team and I are working on a portal applicaiton. When a user requests a page, we get a page object (contianing permissions, actual file to use and what not). We then do a Response.Redirect to "~/Default.aspx". The crazy thing is that when the code to validate access and what not is called from a button click event from within an ajax update panel, response.redirect is pasting a "&f2" or a "/" into the url. So rather than http://localhost/Default.aspx, the webbrowser is being redirected to http://localhost/%f2Default.aspx, and is subsequently returning a 404 error. HttpContext.Current.Response.Redirect("~/Default.aspx", false); Anyone have an idea of why this would occur? And it only happens when the click event fires inside an update panel.

  • Core data and special characters (UTF-8)

    - by MW
    I have an iPhone application using Core Data with an SQLite database in the bottom. I'm writing some text content from the database to a file, but special characters such as Å, Ä and Ö are corrupted in the file (they show up just fine in the application). When creating and inserting data, I am not using any special encoding. I'm just taking the NSString (entered by the user in a UITextField) and putting it in my persistent objects. When saving the file, I use the following code: [csvString writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:&error]; I tried adding a BOM to the beginning of the text ("\xef\xbb\xbf") but it is still corrupted. Anyone has any ideas where the problem might be? Examples of corrupted characters: å becomes ö, ä becomes ä

  • ASP .NET - How to Iterate through a repeater ?

    - by Amokrane
    Hi, What I'm trying to do is iterate through a repeater and read some controls values: foreach (RepeaterItem iter in TablePanier.Items) { string guid = ((HiddenField)iter.FindControl("guid")).Value.ToString(); // nombre exemplaires du livre int nbExemplaires = int.Parse(((System.Web.UI.WebControls.TextBox)iter.FindControl("txtNbExemplaires")).Text.ToString()); } As you can see, I have a HiddenValue and a TextBox. Unfortunately this isn't working, the values are not read correctly. What's wrong? Thank you!

  • Asp.Net MVC does automatic model validation for DateTime but no others

    - by MattSlay
    I'm using MVC 2 with some Models from a LinqToSql project that I built. I see that when I post back to a Controller Action after editing a form that has a DateTime field from the Model, the MVC Html.ValidationMessageFor() helper will nicely display an error beside the Date text box. This seems to happen automatically when the you test ModelState.IsValid() in the Controller Action, as if the MVC model binding automatically knows that the DateTime field cannot be empty. My question is... I have some other string fields in these LinqToSql generated classes that are Not-Nullable (marked as Not Nullable in Sql Server which passes thourgh to the LinqToSql generated classes), so why doesn't Mr. MVC pick up on those as well and display a "Required" message in the ValidationMessageFor() placeholders I have added for those fields? Sure, I have successfully added the MetadataType(typeof) buddy classes to cover these Non-nullable string fields, but it sure does seem redundant to add all this metadata in buddy classes when the LinqToSql generated classes already contain enough info that MVC could sniff out. It MVC validation works with DateTime automatically, why not these Not-nullable fields too?

  • Simple list based output instead of style and javascript ridden ASP.net webforms menu

    - by Mike
    Hi All, Is there a way (or component i could use) to output a simple menu. I just need it output as a list, like you would use for a simple superfish menu. I've looked at the menu control and cssadapters (css friendly) which kind of works, except there is a lot of styles and javascript output with the menu which is destroying the look. If I can't find something that outputs a clean list, my next option is to craft some jquery to delete these styles. This is not my preferred option. If you have a better idea, please let me know. Just something that looks like this: <ul> Main Menu <li> hi </li> <li> second menu <ul> <li> <a href="hi.aspx"> in second menu </a></li> <li> <a href="rabbits.aspx"> hi there </a></li> </ul> </li> </ul> Thanks.

  • ASP.Net MVC 2: How to keep values in the model between posts

    - by Andreas
    I have an edit view that is displaying some model properties as plain text and other model properties as input fields. My problem is that the model properties displayed as plain text are null when the model is returned to the view after a validation error. How do I retain the model values when I don't have input fields for all properties? What is best practice? My first thought is to keep the values of these properties in hidden input elements. <%= Html.HiddenFor(model => model.CustomerName) %> Is this considered a correct solution? Thanks Andreas

  • How do I use custom member properties for people on my .NET website

    - by Jordan S
    I am trying to make an asp.net website using Visual web dev and C# that accesses data in an SQL database. For my site, I need to be able to save and access additional user properties such as age and gender. I have been playing around with the built in .NET Login tools but I don't understand how to keep track of the additional properties (age, gender...) I could store all the users information in my own database but how do I correlate the users data in my DB to the usernames in the member database that is automatically created?

  • Help with route rewrite in asp.net mvc

    - by NachoF
    Im having a really hard time understanding routing. Please help me with this problem. Each of my controllers have these three actions right now Users have Index, Create and Edit Locations have Index, Create and Edit Companies have Index, Create and Edit The thing is, it all gets done through ajax. I have jquery ui tabs with two tabs for each, Create and Edit So the Index method is always the one that gets called for action links. and inside this main view is that you can call(by clicking on the tab icon) the other methods that return an ajax view that gets output into the jqeury tab (I hope thats clear) I have a sidebar with links to the controllers. and to specific methods of these controllers. The wanted behavior is that it should actually go into the Index Method and then with some logic autoload the wanted tab. It all works just fine right now. But my urls are horrible. To get to the create method for Users I have to go this url http://localhost/Users/Index/1 http://localhost/Users/Index/2 I want the behavior of these links to be remapped to these links http://localhost/Users/Create http://localhost/Users/Edit So even though it seems as if you are calling the Create method of the controller you are actualling always calling the Index Method.... (I know how to transform Create into "1" and Edit into two, so dont worry about that part Hope thats clear. Thanks in advance Edit: Just realized that this might not be possible cause then when I actually need to call the methods (with ajax) it wont know what to do.... am I correct?

  • Best practices in ASP.Net code behind pages.

    - by patricks418
    Hi, I am an experienced developer but I am new to web application development. Now I am in charge of developing a new web application and I could really use some input from experienced web developers out there. I'd like to understand exactly what experienced web developers do in the code-behind pages. At first I thought it was best to have a rule that all the database access and business logic should be performed in classes external to the code-behind pages. My thought was that only logic necessary for the web form would be performed in the code-behind. I still think that all the business logic should be performed in other classes but I'm beginning to think it would be alright if the code-behind had access to the database to query it directly rather than having to call other classes to receive a dataset or collection back. Any input would be appreciated.

  • ASP.NET Projects with Two Versions of AjaxControlToolkit

    - by Chris
    In my Solution I have three projects. Project A is a web app and uses version 1.0.10618.0 of the AjaxControlToolkit. I would love to upgrade it to the latest but unfortunately any newer release completely breaks a portion of my site. Project B is also a web app but is a completely new software product and so it uses (and relies on) the latest version of the AjaxControlToolkit. Everything works great. Thought A and B are totally different products they use the same DB and rely on the same ClassLibrary. Project C is a small web app that ties A and B together with certain functionality like forgot password pages. The pages in this app reside in a virtual directory of both A and B. Project C currently uses v1.0.10618.0 of the toolkit so it works with Project A but it fails with project B because the manifest definitions of the dlls don't match (to be expected). What I've done is built a new dll of the toolkit and changed the assembly and namespace to AjaxControlToolkit_v1 and then changed all v1 references to this new dll so the old version and new versions can sit side by side in the same bin folder and nobody complains. I then changed my web.config controls tag to look like this: <add tagPrefix="ajaxToolkit" namespace="AjaxControlToolkit_v1" assembly="AjaxControlToolkit_v1, Version=1.0.10618.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/> This all works except I get a runtime error of: Unknown server tag 'ajaxToolkit:AnimationExtender'. I can't figure out why this is, any ideas on how to remedy it?

  • Data structure for Settlers of Catan map?

    - by templatetypedef
    Hello all- A while back someone asked me if I knew of a nice way to encode the information for the game Settlers of Catan. This would require storing a hexagonal grid in a way where each hex can have data associated with it. More importantly, though, I would need some way of efficiently looking up vertices and edges on the sides of these hexagons, since that's where all the action is. My question is this: is there a good, simple data structure for storing a hexagonal grid while allowing for fast lookup of hexagons, edges between hexagons, and vertices at the intersections of hexagons? I know that general structures like a winged-edge or quad-edge could do this, but that seems like massive overkill. Thanks!

  • ASP.NET MVC and AjaxFileUpload

    - by Jimbojones
    Ok, this is driving me nuts. I have been trying to figure this out forever now. I want to to perform an async upload using ajaxFileUpload. I have it posting the file to my controller just fine, however, when i try to return a JsonResult from it, I get a "Save File As" dialog box. I have tried everything to get around this and i either get an error or the "Save As" dialog. Im assuming that it has something to do with the content type that is being passed in when the file gets posted. I would be greatly appreciative if anyone could help. Thanks in advance!
