  • ASP.Net URL rewirting and redirecting....

    - by DDiVita
    I am trying to wrap my head around a URL rewrtie / redirect project I need to work on. We currently have this url: www.domain.com/Details/Detail.aspx?param1=8&param2=12345 Here is what the rewritten URL will look like: www.domain.com/Param1/8/Param2/12345 I am using the ISAPI_Rewrite filter to allow for the "nice" url and make the page think it is still using the old url. That works fine. Now, I need to redirect users, if they use the old URL, to the new URL. I fgiure I would need to use a combination of the filter and an HTTPModule / Handler to perfomr the redirect. Any ideas?

  • ASP.NET MCV 2 controller-url problems

    - by cc0
    I am still very new to the MVC framework, but I managed to create a controller that reads from a database and writes JSON to an url; host.com/Controllername?minValue=something&maxValue=something However when I move the site to a subfolder; host.com/mvc/ it doesn't seem to be able to call the controller from there when I do it like this; host.com/mvc/Procedure?minValue=something&maxValue=something Did I forget to do something somewhere to make this url call valid from that subfolder? Any help here would be greatly appreciated.

  • Deploying a .Net App Source Control (SVN) over 32-bit AND 64-bit dev stations

    - by Mika Jacobi
    Here is the situation : Our Dev Team has heterogeneous OS systems, scattered between 32-bit and 64-bit. This is not ideal, we are actually planning to homogenize our infrastructure, but in the meantime we have to deal with it. The issue is that when a 32-bit developer checks out a 64-bit solution on SVN, he has to manually change the target platforms all over again to get it compiled (not to mention other side problems) My question is : What clean (though temporary) solution could be addressed in such situation, permitting each developer to keep his default project/platform settings while checking out and in from SVN. I guess that -at least for the first time a project/solution is checked out, a dev still has to tweak the setting manually to compile it properly. After that, according to relevant SVN filters, it is possible to ignore some settings files (which ones, by the way?) I am open to all clever and detailed suggestions. Thanks.

  • Best Practice to write Connection string for heavy traffic ASP.NET Web Application

    - by hungrycoder
    What is the best way to define connection string for a web application that has minimum 500 live users on the internet in terms of connection pooling. And load factors to consider? Suppose I have connection string as follows: initial catalog=Northwind; Min Pool Size=20;Max Pool Size=500; data source=localhost; Connection Timeout=30; Integrated security=sspi" as Max Pool Size is 500 and as live users exceed 500 say 520 will the remaining 20 users experience slower page load?? Or what if I have connection string as follows which doesn't talks anything about pooling or Connection time out? How the application behaves then? initial catalog=Northwind; data source=localhost; Integrated security=sspi" I'm using "Using statements" however to access the MYSQL database.

  • Clean way to output values in ASP.NET MVC Views when value is not null

    - by Swoop
    Is there a better way to write the code below? I have quite a few blocks that are similar, and this is making the code in the Viewpage very messy to work with. The data value with the associated label only needs to be output when certain conditions are met, which is almost always if the value is not null. The options I can think is to use a response.write to atleast minimize the usage of the ASP script tags, or to format the webpage is such a way that the label displays with an appropriate n/a type value. <% if (myData.Balance != null) { %> Balance: <%= String.Format("{0:C}", (myData.Balance))%> <% } %>

  • Create a real time web application using .net framework and azure - very confused

    - by test
    Let us say I would like a simple (yet complex) web application where there is continuous READING AND WRITING to the sql azure database. Let us say I am tracking a location, and I would like it to be updated very frequently (lets take the worst case: 1 second). From the little knowledge I have, I think that this involves the use of the database to continuously write the location to the database, and continuously read from the database to update another person through a website. Do you please have any suggestion which technologies can I use? Is there a simple way? I heard about node.js, signalR. I have no idea how to use them, if they are really what I need. the last tutorial I checked out simply uses a while(true) loop..but I don't think that that's something good to keep a thread continuously busy... Do I have to create some background task? Do I have to create some web service? This is a school project and I wish not to go for the most difficult option, but if there is some sort of solution, challenge accepted :) Can you please help me? Since I have asked many questions here and yet I have no solution in mind

  • Membership and asp.net MVC

    - by Jemes
    I’m building a site that needs users created with different roles and permissions to access different areas of the site. I using mvc 2 but I can’t find much clear guidance on using the Membership tool with mvc to create accounts and roles etc. I tried the web configuration tool which works but I would like to administrate the site remotely. I used the aspnet_regsql tool so I can access the SqlMembershipProvider Schema in my Database. I also need to add more information to a user like profile info and a picture, would I add these to the membership tables or create separate tables for this? Any advice or help would be really helpful? Thanks Jemes

  • ASP.NET Ajax Error: Sys.WebForms.PageRequestManagerParserErrorException

    - by Phil Bennett
    My website has been giving me intermittent errors when trying to perform any Ajax activities. The message I get is Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' So its obviously some sort of server timeout or the server's just returning back mangled garbage. This generally, unfortunately not always, happens when the site has been idle for a while. Anybody else been able to overcome this? Thanks

  • Trouble with ASP.NET MVC auto-scaffolder template

    - by DanM
    I'm trying to write an auto-scaffolder template for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IQueryable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. Here's what I have so far: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; // How do I make this generic? var properties = items.First().GetMetadata().Properties .Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm)); %> <table> <tr> <% foreach(var property in properties) { %> <th> <%= property.DisplayName %> </th> <% } %> </tr> <% foreach(var item in items) { HtmlHelper itemHtml = ????; // What should I put in place of "????"? %> <tr> <% foreach(var property in properties) { %> <td> <%= itemHtml.Display(property.DisplayName) %> </td> <% } %> </tr> <% } %> </table> Two problems with this: I'd like it to be generic. So, I'd like to replace var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; with var items = (IQueryable<T>)Model; or something to that effect. A property Html is automatically created for me when the view is created, but this HtmlHelper applies to the whole collection. I need to somehow create an itemHtml object that applies just to the current item in the foreach loop. I'm not sure how to do this, however, because the constructors for HtmlHelper don't take a Model object. How do I solve these two problems?

  • The cost of finalize in .Net

    - by Jules
    (1) I've read a lot of questions about IDisposable where the answers recommend not using Finalize unless you really need to because of the process time involved. What I haven't seen is how much this cost is and how often it's paid. Every millisecond? second? hour, day etc. (2) Also, it seems to me that Finalize is handy when its not always known if an object can be disposed. For instance, the framework font class. A control can't dispose of it because it doesn't know if the font is shared. The font is usually created at design time so the user won't know to dispose it, therefore finalize kicks in to finally get rid of it when there are no references left. Is that a correct impression?

  • .NET 2.0: Invoking Methods Using Reflection And Generics Causes Exception

    - by David Derringer
    Hi all, I'm new to Stack Overflow, so forgive me. I've just started transititoning over to C# and I am stuck on a problem. I am wanting to pass a generic class in and call a method from that class. So, my code looks as such: public void UpdateRecords<T>(T sender) where T : new() //where T: new() came from Resharper { Type foo = Type.GetType(sender.GetType().ToString()); object[] userParameters = new object[2]; userParameters[0] = x; userParameters[1] = y; sender = new T(); //This was to see if I could solve my exception problem MethodInfo populateRecord = foo.GetMethod("MethodInOtherClass"); populateMethod.Invoke(sender, userParameters); } Exception thrown: "Object reference not set to an instance of an object." Again, I really apologize, as I am nearly brand new to C# and this is the first time I've ever handled reflection and generics. Thank you!

  • Asp.Net MVC Handle Drop Down Boxes that are not part of the Model

    - by Pino
    I have a small form which the user must fill in and consists of the following fields. Name (Text) Value (Text) Group (Group - Is a list of option pulled from a database table) Now the Model for this View looks like so, public string Name { get; set; } public string Value { get; set; } public int GroupID { get; set; } Now the view is Strongly Typed to the above model. What method would one use to populate the drop down list? Since the data is not contained within the Model (It could be contained in the Model) should we be using Temp/View data? A HTML Helper? What would be the ideal way to achieve this.

  • Mdi Children Changed in .Net

    - by Ben
    Hi Is there a simple way of tracking the change of an Mdi's children i.e. when they are created and closed, something like an event OnMdiChildListChanged (I realise this doesn't actually exist). I am also aware that I could have a method within my Mdi that handles the creation of child forms and logs the state of them or even create an Interface that defines that a child form has a "NotifyParent" method that is then called on close of the form, but i was wondering if there was any built in events that i could plumb into? Thanks

  • Getting value from a texbox in asp.net

    - by user279521
    Hi, I have a web page which contains multiple panels (used to show and hide various textboxes) and one particular panel contains textboxes that is used to edit records. However, when I am attemtping to update the table, the txtVendorID.Text.Trim() is blank. SqlConnection con = new SqlConnection(strConn); string sqlUpdateVendor = "usp_Vendor_Update"; SqlCommand cmdUpdateVendor = new SqlCommand(sqlUpdateVendor, con); cmdUpdateVendor.CommandType = CommandType.StoredProcedure; cmdUpdateVendor.Parameters.Add(new SqlParameter("@RecID", SqlDbType.VarChar, 50)); cmdUpdateVendor.Parameters["@RecID"].Value = Request.QueryString["Rec_ID"]; cmdUpdateVendor.Parameters.Add(new SqlParameter("@empid", SqlDbType.VarChar, 11)); cmdUpdateVendor.Parameters["@empid"].Value = txtEmpIDNumber.Text.Trim(); cmdUpdateVendor.Parameters.Add(new SqlParameter("@VendorName", SqlDbType.VarChar, 100)); cmdUpdateVendor.Parameters["@VendorName"].Value = txtVendorName.Text.Trim(); Any idea why the textbox does not contain a value?

  • ASP.NET MVC - hiding id in URL?

    - by mcfroob
    I'm building a basic blog application just now, for viewing data I'm just using the default route, i.e. - routes.MapRoute ( "Default", // Route name "{controller}/{action}/{id}", new { controller = "Blog", action = "Index", id = UrlParameter.Optional } ); So that when you go to mysite.com/View/12 it displays the blog with id 12. I want to modify the URLs so that they look as follows: mysite.com/View/2010/06/01/this-is-the-title. I could have a URL mapping like - routes.MapRoute( "View", "View/{year}/{month}/{day}/{title}", new { controller = "Blog", action = "View" } ); But then I'm not passing the ID into the Controller action so I would have to search on the date and title which doesn't feel right. On the other hand, if I pass the ID in it will show up in the URL which isn't what I'm aiming for either. Is there any way to redirect to the URL I want in the controller action after passing only the ID in as a paramter, or to pass the ID into the a Map Route but hide it in the URL? Thanks for your help!

  • VB.NET Window Screen Capture (ALT+PRINTSCREEN)

    - by Steve Thomas
    Hi, I found that code somewhere and I find it quite useful but I would like to find a way to make it work so it capture only the given window target. Maybe with a processID or Window Name. Even if that window is not active. I do not want to make that window active but want to get a screen capture like if I was doing Alt+PrintScreen on it. Here is the code that works for full Screen Capture Private bmpScreenShot As Bitmap Private gfxScreenshot As Graphics bmpScreenShot = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb) gfxScreenshot = Graphics.FromImage(bmpScreenShot) gfxScreenshot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy) bmpScreenShot.Save(fileName, ImageFormat.Png) I use the Visual Basic 2008 Express Thank you in advance!

  • ASP .NET - What's going on behind an Eval() ?

    - by Amokrane
    Hi, I'm trying to understand how Eval() works for a specific purpose. I'm working on a project I don't really know and I need to read some data and put them in drop down list. These data are already read and are displayed inside an ItemTemplate. I noticed there are read using the Eval() method. Something like: <ItemTemplate> <a href="...=<%# Eval("foo") %>></a> </ItemTemplate> I need to know where Eval is getting these data from in order to discover where I should read them for my drop down list! But I didn't really understand how it works! I know that Eval() evaluates data binding expressions at runtime but where do you think I should take a look at? Thank you
