I want to build a proxy site that renders any URL. Given an url, I need to replace all html links, css links and js urls from href="/original.htm" to [URL] sort of. How can I do? is there a ready-to-use framework? I use ASP.NET and C#.
View 1 Repliesthe site normally works fine in all popular browsers including firefox, chrome, safari and ie.
but doesn't work in ie 8 when it's redirected via a proxy server and it gives an error saying
"Message: 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.

View 1 RepliesThis is not a programming question per se, but rather an attempt to find the adequate technology to use for my objective. My mandate is to build an ASP.NET Web Application. However, on certain pages, some client-side information needs to be fetched by interacting with hardware on the client's computer, for example a barcode reader or an RFID tag reader. My first reflex was to think "ActiveX" controls with, perhaps, some AJAX coding to fetch the required values from said control. However, I am not sure if I am up to date with the latest tech trends. The solution I'm looking for will let me design a user control that plugs into my ASP.NET Web Application, lets me interact with client-side hardware, and can be automatically downloaded from the Web Application itself (I can't predict which computers will access my Web Application). Which technology(ies) should I go for?
View 2 RepliesI'm currently writing a web app in ASP.NET MVC 1.0 (although I do have MVC 2.0 installed on my PC, so I'm not exactly restricted to 1.0) -- I've started with the standard MVC project which has your basic "Welcome to ASP.NET MVC" and shows both the [Home] tab and [About] tab in the upper-right corner. Pretty standard, right? I've added 4 new Controller classes, let's call them "Astronomer", "Biologist", "Chemist", and "Physicist". Attached to each new controller class is the [Authorize] attribute. For example, for the BiologistController.cs
[Authorize(Roles = "Biologist,Admin")]
public class BiologistController : Controller
{
public ActionResult Index() { return View(); }
}
These [Authorize] tags naturally limit which user can access different controllers depending on Roles, but I want to dynamically build a Menu at the top of my website in the Site.Master Page based on the Roles the user is a part of. So for example, if "JoeUser" was a member of Roles "Astronomer" and "Physicist", the navigation menu would say:
[Home] [Astronomer] [Physicist]
[About]
And naturally, it would not list links to "Biologist" or "Chemist" controller Index page. Or if "JohnAdmin" was a member of Role "Admin", links to all 4 controllers would show up in the navigation bar. Ok, you prolly get the idea... Now for the real question... Starting with the answer from this StackOverflow topic about Dynamic Menu building in ASP.NET, I'm trying to understand how I would fully implement this. (I'm a newbie and need a little more guidance, so please bare with me.) The answer proposes Extending the Controller class (call it "ExtController") and then have each new WhateverController inherit from ExtController.
My conclusion is that I would need to use Reflection in this ExtController Constructor to determine which Classes and Methods have [Authorize] attributes attached to them to determine the Roles. Then using a Static Dictionary, store the Roles and Controllers/Methods in key-value pairs. I imagine it something like this:
public class ExtController : Controller
{
protected static Dictionary<Type,List<string>> ControllerRolesDictionary;
protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
// build list of menu items based on user's permissions, and add it to ViewData
IEnumerable<MenuItem> menu = BuildMenu();
ViewData["Menu"] = menu;
}
private IEnumerable<MenuItem> BuildMenu()
{
// Code to build a menu
SomeRoleProvider rp = new SomeRoleProvider();
foreach (var role in rp.GetRolesForUser(HttpContext.User.Identity.Name))
{
}
}
public ExtController()
{
// Use this.GetType() to determine if this Controller is already in the Dictionary
if (!ControllerRolesDictionary.ContainsKey(this.GetType()))
{
// If not, use Reflection to add List of Roles to Dictionary
// associating with Controller
}
}
}
Is this doable? If so, how do I perform Reflection in the ExtController constructor to discover the [Authorize] attribute and related Roles (if any) ALSO! Feel free to go out-of-scope on this question and suggest an alternate way of solving this "Dynamic Site.Master Menu based on Roles" problem. I'm the first to admit that this may not be the best approach.
I've been using a repeater to build a website's site map page by binding to the web.sitemap file. For example, to display 2 levels of links:
[Code]....
So far, everything works well. However, in some cases, I do not want to display certain pages in the site map. I've added a custom attribute to each node (nodisplay= 'true').How can i check for this attibute, and avoid it from being displayed by in the repeater.
I have a question regarding a situation that occurs with GridView, ObjectDataSource in ASP .NET application. The GridView is linked to the ObjectDataSource and both are included within an UpdatePanel letting the GridView to fill in an asynchronous way from a form in the same page so it gets more rows as the user enters the data:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ReadOnly="True"
SortExpression="Name" />
<asp:BoundField DataField="Periodicty" HeaderText="Periodicty" ReadOnly="True"
SortExpression="Periodicty" />
</Columns>
</asp:GridView>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
SelectMethod="GetSessionNames" TypeName="Simulation"></asp:ObjectDataSource>
<asp:Label ID="Label27" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="NewWebSessionButton" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
I start the project with Visual Studio 2008, fill the form and it works correctly. Then I stop the execution: rerun again and the data I entered in the previous run is in the GridView. Is like some sort of cache saved the data from the session before. I checked that EnableCaching property is set to false for the ObjectDataSource. If I Rebuild Web Site in Visual Studio (not just Build) then it works corretly leaving the GridView empty. Is this caused just becuase of Visual Studio? Can it be turned off? And will it happen in the final IIS it will run on?
I want to build a survey system where you can build a form with questions and some answers to these questions and then members who will log in will be able to take the test.

View 2 RepliesI have a large solution which has multiple apps which all share some common site elements (masterpages, navigation, etc).
Currently, all of these get built into a single DLL
If my structure looks like:
WebRoot
- Common/
- Shared/
- Images/
- App1/
- App2/

Is there a build tool which will allow me to build WebRoot.dll, App1.dll, App2.dll? I don't believe this is possible in VS2008 or the MSBuild tool.
I have a TFS build set up to deploy an ASP.net project to a test server.The build works great, and deploys to the test server fine, but instead of putting it into the Website directory that my IIS webserver is configured for, it puts the build into Website_20100511.6
Why is the date suffixed to the directory name? Is there a way to turn that off so I can publish directly to the Website?

When I try to serialize <%: Html.CheckBox("Something", true) %> in jquery (using form.serialize()) I get two checkboxes, one says true, and the other false.

have a view which invokes partial view. I am having trouble getting to updated values in model used in partial view on the post back. Here is the razor code for my main view:
[Code]....
The partial view renders a drop down box with several values. The Razor code for this partial view is shown below:

The controller action method to get the page is shown below:

When user changes the dropdown option to something else and clicks on submit button, my service side controller method is invoked. The example code is shown below:
[Code]....
This issue is that thisModel.MyInnerModel.MyOption does not have user selected value. If I do away with partial view and keep all Razor code in the main view, every thing works as expected and I can see the changed value in thisModel.MyInnerModel.MyOption property.
I'm using iTextSharp to print a PDF document. Everything goes ok until I have to print the company logo in it.
First I noticed that the logo had poor quality, but after testing with several images, I realize that was the iTextSharp rendering it poorly.The test I did to say this was to print the PDF using my code and then edit the document with Acrobat 8.0 and I drew an image. Then printed the two documents and saw the noticeable difference.My question is that if anyone know if this can be due to a scaling problem where I'm failing to tell iTextSharp how it must render the image or is an iTextSharp limitation.
The code to render the image is the following:

The method ResizeImage() do the resizing of the width and height respecting the aspect ratio and keeping in a max width and a max height limits.

In addition, I have a controller that is called when the form is posted back:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(FormCollection collection)
{ [code]...
The problem is that none of the data in the table is being captured in the FormCollection in the Post. The TextBoxes pass data as expected so I know the wireup is working.I read from some other posts that you need a value for the name property - but that did not work. Also, I read that you need to put the data inside a TextBox inside the TD. Instead of grasping at straws, does anyone know the best pattern to pass the data from a Table back into the FormCollection?
btw: I tried to copy/paste formatted test in from Word. No dice. Ugh.
I took over some old php application with MySQL as database. Inside the database, there are tables including content with localized strings (therefore containing special chars)Currently there is a PHP application accessing that database. My job is to create an ASP.net (C# codebehind) application that accesses that strings as well. That works, as far as encoding goes.If I try to access these strings, I do get a kind of encoding problem, like 'Ändern' and 'Prüfzeichen', but only in the ASP.net application. The PHP app sets utf-8 as charset and the strings are perfectly rendered. In the ASP.net application it's gibberish, regardless of the page encoding.In the MySQL database, the charset for the specified table 'translations' is set to 'latin --cp1252 West European' and collation to 'latin_swedish_ci'.I can't seem to figure out what PHP apparently does, and ASP.net does not. I traced the php code and could not find any sign of special encoding while getting a string from the database.The question is, how can I ensure correct encoding inside the ASP.net application without modifying the database, because big changes at the php code are not possible?
View 3 RepliesI have a TabContainer with 3 TabPanels. The container has a yellow background. On the first tab the yellow background is the height of all the controls.
