  • ASP.NET Build Images Links Dynamically

    - by coson
    Good Day, I am developing a website that has product images on an external server. I have code that tests to see if the image exists like (pseudo code): DynamicString = FunctionThatCreatesDynamicString() ' DynamicString = "http://external_server/path/to/file1.jpg" If ImageExists(DyanmicString) = StatusCode.200 Then ' Embed link in ASP.NET page Else ' Embed not found image in ASP.NET page End If My code builds fine and appears to execute. The problem occurs when I attempt to view the external link in a browser, the image appears properly (I have to authenticate first, but that's OK considering I'm on an internal network and this app will be used internally). However, when I attempt the view the source in my generated HTML page, I am seeing the image to the "Not Found" image when I know the image is there. I compared all the characters in my dynamically assembled to the external link and all the characters are matching up correctly. I'm wondering if the authentication has anything to do with why the image is not rendering properly on my rendered HTML. Any thoughts? TIA, coson

  • Why is there no .NET Community Process?

    - by michielvoo
    I was doing some research into general topics of software engineering and I came across the Java Community Process website: The JCP is the mechanism for developing standard technical specifications for Java technology. Anyone can register for the site and participate in reviewing and providing feedback for the Java Specification Requests (JSRs), and anyone can sign up to become a JCP Member and then participate on the Expert Group of a JSR or even submit their own JSR Proposal. Seems like a good idea to me, and there are lots of very well written specifications and reference implementations on the JCP website. So why is there no .NET Community Process? Is that something that Microsoft could or should start? Maybe they could install it on Codeplex.net and hand over the keys to the community.

  • Navigating from VB.NET code to C# code problem

    - by user181218
    Hi, There seemes to be a consistent problem with the following situation: Say you have a VS2008 solution, consisting of a (say console) application written in vb.net, and a class library written in c#. The application references the class library project. This, of course, complies and works well. However, when you right-click (in the vb.net application code) a function prototype/object type defined in the class library, and select "Go to definition", the object browser opens providing you with the the list of methods available for the class the class library consists of. BAD. However, if you try to do the same when both the application and cl are in c#, this works just fine and you navigate driectly to the relevant function/class.GOOD. Known issue? Solvable?

  • DNS Lookup in simple C#/asp.net ajax call is extremely slow

    - by Ryan
    I'm running this out of the VS 2008 debugger on Windows 7, running .Net 3.5. The idea was to make all ajax requests with jQuery only, rather than .net, following some tutorials online. Default.aspx - HTML page, jquery triggers method in Default.aspx.cs http://pastebin.com/pxBvKA2H Default.aspx.cs - C# Webform, just defines a GetDate fuction, which only returns a string for now (trying to eliminate any possible issues) (can only post one hyperlink...) pastebin.com/pnHn50hu The ajax query takes longer than it should. Profiling with firebug revealed that it took 1.03 ms. 1s DNS Lookup | 26ms Waiting | 1ms Receiving EDIT: It continues to take the same set of times if you continue to click and resubmit the request. Is there anything I can do to cut down on the DNS Lookup time / what did I do wrong? Thanks for any help.

  • asp.net login control with role redirection

    - by Eatdoku
    Hi, I am using a asp.net login control with one of my asp.net application to authenticate users. I also have roles defined as well. Some of the directories are setup so only users with ROLE "MANAGER" are able to access pages under those directories. If the user does not have "MANAGER" role, he will simply be redirect back to the login page. so my question is that for the out of box login control, is there a way to show the proper login fail error message? for user trying to login but does not have a proper ROLE assigned to them, instead of a generic error message saying "login failed" thanks.

  • Using Jquery and Ajax in ASP.NET

    - by xkcd
    I am using ajax and jquery to load contents into a div. My jquery looks like this $("a.trigger").click(function() { $.ajax({ type: "POST", url: "GetStuff.aspx", data: "id=0", success: function(response){ $("#contentDiv").html(response); } }); }); In GetStuff.aspx I would like to write some asp.net html controls like private void Page_Load(object sender, System.EventArgs e) { Response.Expires = -1; Response.ContentType = "text/plain"; Response.Write("<asp:Label id=\"label1\" runat=\"server\" text=\"helloworld\"/>"); Response.End(); } However the label does not appear on the page. I tried to put the asp:Label in my aspx file like this <%@ Page Language="C#" Inherits="Untitled.GetStuff" %> <asp:Label id="label12" runat="server" text="helloworld2"/> It also does not work. How can I get asp.net html controls to show up?

  • ASP.NET JavaScript File Embeded In DLL With GZIP

    - by Lee Hesselden
    We have several fairly large JavaScript files embedded into a single script resources DLL. This is then consumed by multiple projects by way of a reference and page includes via the ASP.NET script manager. This keeps things nice and neat within our ASP.NET pages and requires very little work to integrate into new projects. The problem is that some of these script files are quite larger (approx 100KB) and take time to download. By running minify on them before embedding this is reduced down a lot (around 70KB) but not enough. What we would like to do is GZIP the files before they are embedded. However, just gzipping the files causes syntax errors as the content is not unzipped. There is a content type "text/javascript" applied in AssemblyInfo when the resource is embedded but we can't find a way to specify content-encoding. Is there any way to make this work without having to write a httpmodule/handler (which would mean changing the config for all consuming projects)?

  • Displaying a Sorted, Paged, and Filtered Grid of Data in ASP.NET MVC

    Over the past couple of months I've authored five articles on displaying a grid of data in an ASP.NET MVC application. The first article in the series focused on simply displaying data. This was followed by articles showing how to sort, page, and filter a grid of data. We then examined how to both sort and page a single grid of data. This article looks at how to add the final piece to the puzzle: we'll see how to combine sorting, paging and filtering when displaying data in a single grid. Like with its predecessors, this article offers step-by-step instructions and includes a complete, working demo available for download at the end of the article. Read on to learn more! Read More >

  • Actors in Scala.net

    - by weijiajun
    I have recently completed some study of erlang, and was intrigued by scala for its feature set and the ease of interpolating with java (and possibly .net) applications. I am finally studying actors and was wondering if there is an actor mechanism that currently works in .net. I have looked at the libararies that come down with sbaz and have found that there is a scala.Concurrent but no scala.actors.Actor. I tried to use the scala.Concurrent.Channel but was unable to use the ! to send messages. I was just wondering if this is something that is currently available and if so how do you go about setting it up.

  • Aldon and .Net Development

    - by David Stratton
    I'm looking for feedback from .Net developers who have experience with Aldon as a lifecycle management platform. We're seriously considering using Aldon for lifecycle management including source control, automated builds, etc. I know there are a lot of other options out there, but ours is primary an AS/400 shop (with AS/400 programmers outnumbering .Net developers 6 to 1), and Aldon is used already by our iSeries team. The benefit we're looking for is having one lifecycle management suite. Basically, I'm looking for opinions from people who have used Aldon and another set of tools (perhaps TFS, or a combination of SVN, Cruise Control, etc). If you've worked with both, do you have a recommendation on whether this is a good idea, or a bad idea? It's obviously a big choice, so any feedback would be helpful.

  • Migrate from VB.net to C#

    - by rowmark
    Hello Experts, I have been developing applications using VB.net for the past 5 years. As I tried to learn Java earlier and found it very difficult for me I did stick on to VB.net. And for me C# is more or less similar to Java. Now I cannot get away with it. I have to code on C#. Is there a way I can get to speed with C# fast. I would really appreciate if you can let me know your thoughts and if there are any good resources I can try.

  • Using ASP.NET Session for Lifetime Management (Unity)

    - by Sigray
    I am considering using Unity to manage the lifetime of a custom user class instance. I am planning on extending the LifetimeManager with a custom ASP.NET session manager. What I want to be able to do is store and retrieve the currently logged in user object from my custom classes, and have Unity get the instance of User from the session object in ASP.NET, or (when in a Win32 project) retrieve it statically or from the current thread. So far my best solution is to create a static instance of my Unity container on startup, and use the Resolve method to get my User object from each of my classes. However, this seems to create a dependency on the unity container in my other classes. What is the more "Unity" way of accomplishing this goal? I would like to be able to read/replace the current User instance from any class.

  • Using Report (Reporting Services) parameter values in ASP.NET page

    - by noup
    I have a report (Reporting Services) integrated into an ASP.NET that shows dropdownlists to select report parameter values. The dropdownlists are populated using direct database selects, though I see the report RDL files do contain the paramter values and datasets as defined in the report designer. Is it possible to obtain the report parameters "available values" in ASP.NET to populate the dropdownlists? This would avoid some code duplication. Update If the parameter doesn't use a query for available values, the following works: foreach (ValidValue value in this.ReportViewerControl.ServerReport.GetParameters()["myParameter"].ValidValues) { this.DropDownListControl.Items.Add(new ListItem(value.Label, value.Value)); } Still haven't found a way to access report datasets though...
