  • Will it be possible to use any asp.net and silverlight controls in Intraweb XII?

    - by user193655
    I am researching a lot on intraweb, I read that in Intraweb XII (when will this be released?) it will be possible to have: 1) "silverlight enabled controls" (mentioned here, this is the old IW XI roadmap anyway silverlight task has been moved to XII now) 2) "IntraWeb XII [...] will contain the integration with CrossTalk and ASP.NET" (mentioned here, check for Intraweb XII paragraph). Now I don't understand what this mean in detail. I think IW is very cool, but it lacks a good choice of components, there is only one vendor (TMS) that makes good components, but of course one can wonder "why to be limited to one vendor when I can use more components from more vendors"? So does anyone (ideally from IW team, or that really knows the inner workings of IW XII, I mean the details of the roadmap, since XII is not being developed yet) know what the bold sentences above mean? Will this mean I can use inside IW 3rd party components from any ASP.NET and Silverlight vendor like Telerik, DevExpress, ComponentOne, and many, many, more?

  • Pop-up Window was moved but its image still left behind.

    - by andrew
    Hi, I'm using VS 2005 and .NET framework 2.0 SP2 to build an application with a datagridview in it. I'm using Microsoft Word 11.0 Object Library to do the spelling checker on one of the field in datagridview. When it detected a spelling and grammar window would pop-up open on top of the datagridview. The problem I got was when I moved the pop-up window to the new location, there's still an image of the pop-up window left behind the previous location. The more I moved the more of those copied image would be created on screen. How I can overcome this problem? Thanks in advance, Andrew

  • How to prevent MSBUILD from copying dependent GAC assemblies to bin

    - by Matt Wrock
    I have a msbuild task that builds my solution and I am migrating it from .net 3.5 to 4.0. I have some dependent DLLs that have Local Copy set to true. The 4.0 version of msbuild is not only copying the dependent DLL (which I want), it is also copying all dependent assemblies of that DLL from the 32 bit version of the GAC to my bin. Not only do I not want these files being copied from the GAC, I especially do not want the 32 bit versions for this 64 bit build. Has the behavior changed in msbuild 4.0? And does anyone know how to force msbuild to use the behavior in 3.5?

  • How can I send a GET request containing a colon, to an ASP.NET MVC2 controller?

    - by Cheeso
    This works fine: GET /mvc/Movies/TitleIncludes/Lara%20Croft When I submit a request that contains a colon, like this: GET /mvc/Movies/TitleIncludes/Lara%20Croft:%20Tomb ...it generates a 400 error. The error says ASP.NET detected invalid characters in the URL. If I try url-escaping, the request looks like this: GET /mvc/Movies/TitleIncludes/Lara%20Croft%3A%20Tomb ...and this also gives me a 400 error. If I replace the colon with a | : GET /mvc/Movies/TitleIncludes/Lara%20Croft|%20Tomb ..that was also rejeted as illegal, this time with a 500 error. The message: Illegal characters in path. URL-escaping that | results in the same error. I really, really don't want to use a querystring parameter. related: Sending URLs/paths to ASP.NET MVC controller actions

  • How to secure access to SWF file using ASP.NET?

    - by elsharpo
    hi guys, We have a swf file that we want to secure and make available only to authorized users. I embedded the file in an aspx page and that works fine, since ASP.NET handles the aspx page, I can use ASP.NET authorization features and in the web.config restrict the access to roles="AllowedUsers" for example. However smart users could still get to the file by accessing directly for example www.mysite/flash.swf. We want to make that kind of access secure. Any help would be greatly appreciated! Thanks!

Is this bug? regards, Tomas My code static void Main(string[] args) { Arguments CommandLine = new Arguments(args);

  • stringtemplate .net dynamic object

    - by Mark Milford
    Hi I am using string template to render some content, but the content may be variable so not sure how to pass it in (using .net / c#) Basic idea is I have a List which need to end up as parameters, e.g. List<KeyValuePair<string, object>> ret = new List<KeyValuePair<string, object>>(); ret.Add(new KeyValuePair<string, object>("elem1", true)); ret.Add(new KeyValuePair(string, object>("elem2", false)); Now I want these to show up in string template as: $item.elem1$ $item.elem2$ I can get them to be $elem1$ or $elem2$ but i need them inside of a structure. So I in effect need to convince the string template setAttribute that I'm passing in an object with properties elem1 and elem2 when in fact I have a List of KeyValuePairs. Thanks

  • C# .NET MVC Call an action from another controller

    - by Brian
    I have two different objects: contracts, and task orders. My requirements specify that in order to view the Details for either object, the Url should be "http://.../Contract/Details" or "http://.../TaskOrder/Details" depending on which type. They are both very similar and the details pages are almost identical, so I made a class that can either be a contract or a task order, and has a variable "objectTypeID" that says which type it is. I wrote the action "Details" in the task order controller, but now I want to call that from the contract controller instead of recopying the code. So is there any way to have the url still say ".../Contract/Details" but call the action in the TaskOrder controller instead? I tried using TaskOrderController TOController = new TaskOrderController(); TOController.Details(id); This would have worked except that I can't use the HttpContext.Session anymore, which I used several times in the action.

  • Default Object being modified because of LINQ Query

    - by msarchet
    I'm doing the following code to filter a list of objects before it gets sent off to be printed. Dim printList As New List(Of dispillPatient) For Each pat As dispillPatient In patList If (From meds In pat.Medication Select meds Where meds.Print = True).Count > 0 Then Dim patAdd As New dispillPatient patAdd = pat patAdd.Medication = DirectCast((From meds In pat.Medication Select meds Where meds.Print = True).ToList, List(Of dispillMedication)) printList.Add(patAdd) End If Next What is happening is patList, which is my initial list, for every dispillPatient inside of it, that specific patients Medication object (which is another list), is being shorten to the list that is returned to the patAdd object. I think this has something to do with both the way that .NET makes the copy of my pat object when I do patAdd = pat and the LINQ query that I'm using. Has anyone had a similar issue before and\or what can I do to keep my initial list from getting truncated. Thanks

  • TcpListener.Start() does not open the port

    - by SoMoS
    Hello, I have a class that inherits from the TcpListener, this class Shadows the Start method just to call the base Start() and the base BeginAcceptTcpClient(). From time to time the method is called but the port is not opened (netstat does not show the port open). The class looks like this Public Class ExtendedTcpListener Inherits System.Net.Sockets.TcpListener Public Shadows Sub Start() SyncLock (m_stopLock) MyBase.Start() MyBase.BeginAcceptTcpClient(AddressOf Me.CompleteAcceptTcpClient, Me) My.Application.Log.WriteEntry("Extended Tcp Listener started ...", TraceEventType.Verbose) End SyncLock End Sub Any idea on what's happening or how to debug the issue? As the Start() is called without exception I expected to find the port always opened (the log is always written). Extra information: when the Start method works fine it works each time until app is restarted. When the Start method does not work it won't work again until the app is restarted.

  • WPF: "Items collection must be empty before using ItemsSource."

    - by Zack Peterson
    I'm trying to get images to display in a WPF ListView styled like a WrapPanel as described in this old ATC Avalon Team article: How to Create a Custom View. When I try to populate the ListView with a LINQ-to-Entities queried collection of ADO.NET Entity Framework objects I get the following exception: Exception Items collection must be empty before using ItemsSource. My code… Visual Basic Private Sub Window1_Loaded(...) Handles MyBase.Loaded ListViewImages.ItemsSource = From g In db.Graphic _ Order By g.DateAdded Ascending _ Select g End Sub XAML <ListView Name="ListViewImages" SelectionMode="Single" ItemsSource="{Binding}"> <local:ImageView /> </ListView> I put a breakpoint on that line. ListViewImages.ItemsSource is Nothing just before the LINQ assignment.

  • Slow SelectSingleNode

    - by Simon
    I have a simple structured XML file like this: <ttest ID="ttest00001", NickName="map00001"/> <ttest ID="ttest00002", NickName="map00002"/> <ttest ID="ttest00003", NickName="map00003"/> <ttest ID="ttest00004", NickName="map00004"/> ..... This xml file can be around 2.5MB. In my source code I will have a loop to get nicknames In each loop, I have something like this: nickNameLoopNum = MyXmlDoc.SelectSingleNode("//ttest[@ID=' + testloopNum + "']").Attributes["NickName"].Value This single line will cost me 30 to 40 millisecond. I searched some old articles (dated back to 2002) saying, use some sort of compiled "xpath" can help the situation, but that was 5 years ago. I wonder is there a mordern practice to make it faster? (I'm using .NET 3.5)

  • AppDomain.CurrentDomain.DomainUnload not be raised in Console app

    - by Guy
    I have an assembly that when accessed spins up a single thread to process items placed on a queue. In that assembly I attach a handler to the DomainUnload event: AppDomain.CurrentDomain.DomainUnload += new EventHandler(CurrentDomain_DomainUnload); That handler joins the thread to the main thread so that all items on the queue can complete processing before the application terminates. The problem that I am experiencing is that the DomainUnload event is not getting fired when the console application terminates. Any ideas why this would be? Using .NET 3.5 and C#

  • global variable and Python

    - by rejinacm
    A global variable created in one function cannot be used in another function directly. Instead I need to store the global variable in a local variable of the function which needs its access. Am I correct? Why is it so?

  • Exception when ASP.NET attempts to delete network file.

    - by Jordan Terrell
    Greetings - I've got an ASP.NET application that is trying to delete a file on a network share. The ASP.NET application's worker process is running under a domain account (confirmed this by looking in TaskManager and by using ShowContexts2.aspx¹). I've been assured by the network admins that the process account is a member of a group that has Modify permissions to the directory that contains the file I'm trying to delete. However, it is unable to do so, and instead I get an exception (changed the file path to all x's): System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. --- System.UnauthorizedAccessException: Access to the path '\xxxxxxx\xxxxxxx\xxxxxxx\xxxxxx.xxx' is denied. Any ideas on how to diagnose/fix this issue? Thanks - Jordan ¹ http://www.leastprivilege.com/ShowContextsNET20Version.aspx

  • How to add request validation errors to ModelStateDictionary in ASP.NET MVC?

    - by Morten Christiansen
    Investigating the security of a system I'm building with ASP.NET MVC 2 led me to discover the request validation feature of ASP.NET - a very neat feature, indeed. But obviously I don't just want to present the users with the Yellow Screen of Death when they enter data with HTML in, so I'm out to find a better solution. My idea is to find all the fields that have invalid data and add them to the ModelStateDictionary before invoking the action such that they automatically appear in the UI as error messages. After googling this a bit it appears that no one have implemented this before which I find puzzling since it seems so obvious. Does anyone here have a suggestion on how to do this? My own idea is to supply a custom ControllerActionInvoker to the controller, as described here, that somehow checks for this and modifies the ModelStateDictionary but I'm stuck on how to do this last bit. Just catching HttpRequestValidationException exceptions does not seem a useful approach since it does not actually contain all the information I need.

  • Using implicit conversion as a substitute for multiple inheritance in .NET

    - by Daniel Plaisted
    I have a situation where I would like to have objects of a certain type be able to be used as two different types. If one of the "base" types was an interface this wouldn't be an issue, but in my case it is preferable that they both be concrete types. I am considering adding copies of the methods and properties of one of the base types to the derived type, and adding an implicit conversion from the derived type to that base type. Then users will be able treat the derived type as the base type by using the duplicated methods directly, by assigning it to a variable of the base type, or by passing it to a method that takes the base type. It seems like this solution will fit my needs well, but am I missing anything? Is there a situation where this won't work, or where it is likely to add confusion instead of simplicity when using the API?

  • Biztalk - local variable in expression shape

    - by Jeremy Stein
    Sometimes when I'm writing XLANG/s code in an expression shape, it would be more readable if I could just use a temporary variable within the scope of that one code block. I hate to clutter up the entire orchestration with a variable declaration. Is there a way to declare a variable within an expression shape?
