• Get timestamp from Authenticode Signed files in .NET

  - by SlavaGu

  We need to verify that binary files are signed properly with digital signature (Authenticode). This can be achieved with signtool.exe pretty easily. However, we need an automatic way that also verifies signer name and timestamp. This is doable in native C++ with CryptQueryObject() API as shown in this wonderful sample: How To Get Information from Authenticode Signed Executables However we live in a managed world :) hence looking for C# solution to the same problem. Straight approach would be to pInvoke Crypt32.dll and all is done. But there is similar managed API in System.Security.Cryptography.X509Certificates Namespace. X509Certificate2 Class seems to provide some information but no timestamp. Now we came to the original question how can we get that timestamp of a digital signature in C Sharp?

• ASP.NET MVC - Parent-Child Table Relation - how to creat Children in MVC (example request)

  - by adudley

  Hi All. In a standard setup of Parent Child relation, lets say Project and Task. Where a Project is made up of lots of Tasks. So in a standard RDB, we have a Project (ID, Name, Deadline) Task (ID, FK_To_Project, Name, Description, isCompleted) this is all very straight forward. We have an MVC View that views Projects, so we get a nice list of all the project Names next to each deadline. Now we want to CREATE a new PROJECT. The Edit view opens, we type a name, say, 'Make a cup of Tea', with tomorrow as the deadline! Still in this view/web page, I would like a list of all the Child Tasks, in a standard list, with Edit, Delete, and a Create/Add Task button too, just below the 'parent table' details. The simplest way to describe this, is the Parents Table Create/Edit view, with the Childes List View Below it. 1) The ideal solution will also allow my Child Table (Tasks) to have Children also (for more complex scenarios) , and so on, and on, and on. 2) If I navigate away from my Created Project, I don’t want all sorts of random stuff laying around, they went away, it’s gone! 3) I’d expect all the same functionality when Editing an existing project. I’m struggling with the ‘Add New Child’, I had a model dialog (jquery) and all was well, but now when editing an existing child/task, I need to populate the Child Edit, which is a pain and will need loads of java script I think :( How can this be achieved in MVC, does anybody have any examples?

• Enumerating .NET assembly resources at runtime

  - by Alex_P

  I have a resource assembly with image files in it that are built using Resource or Content build action. This makes these files accessible using the Uris. However I cannot find the way to enumerate such resources. If I set the build action to Embedded Resource it becomes possible to enumerate the files with the following code: string[] resources = Assembly.GetExecutingAssembly().GetManifestResourceNames(); but it in turn makes these files inaccessible using Uris. The question is - how to enumerate resources that are compiled with either Resource or Content build action? NOTE: As Thomas Levesque pointed out it is possible to enumerate such resources by leveraging the AssemblyAssociatedContentFileAttribute, but it seems to only work for WPF Application assemblies and not for class library ones. So the question is still open.

• C# .NET: Ascending comparison of a SortedDictionary?

  - by Rosarch

  I'm want a IDictionary<float, foo> that returns the larges values of the key first. private IDictionary<float, foo> layers = new SortedDictionary<float, foo>(new AscendingComparer<float>()); class AscendingComparer<T> : IComparer<T> where T : IComparable<T> { public int Compare(T x, T y) { return -y.CompareTo(x); } } However, this returns values in order of the smallest first. I feel like I'm making a stupid mistake here. Just to see what would happen, I removed the - sign from the comparator: public int Compare(T x, T y) { return y.CompareTo(x); } But I got the same result. This reinforces my intuition that I'm making a stupid error.

• .NET ThreadPool QueueUserWorkItem Synchronization

  - by ikurtz

  I am employing ThreadPool.QueueUserWorkItem to play some sound files and not hanging up the GUI while doing so. It is working but has an undesirable side effect. While the QueueUserWorkItem CallBack Proc is being executed there is nothing to stop it from starting a new thread. This causes the samples in the threads to overlap. How can I make it so that it waits for the already running thread to finish running and only then run the next request? EDIT: I did: Thread t = new Thread(FireAttackProc(fireResult)); t.Start(); but it gave me some errors. How do I specify a thread method with parameters?

• jquery Fullcalendar : dynamic events function asp.net mvc

  - by Eran

  Hi, I'm integrating Fullcalendar into my app. Consider a manager interface where he can select an employee and then view this employee's calendar. Now basically I'm using the following jquery code in my view: <script type="text/javascript"> $(document).ready(function() { $("#calendar").fullCalendar({ defaultView: 'agendaWeek', isRTL: true, axisFormat: 'HH:mm', editable: true, events: "/Scheduler/CalendarData" }); }); </script> Now I would like to have the controller function assigned to the events to retrieve the specific user selected by the manager: events: "/Scheduler/CalendarData/<current_user_name> Is there any way to retrieve the selected employee user name from the view (or rather pass it to the view from the controler) and then pass it onto the bound events function? I hope I was clear enough... Thanks in Advance, Eran

• VB.NET GroupBy LINQ statement

  - by Jason

  I am having a bear of a time getting this to work. I have a List(Of MyItem) called Items that have a OrderId property on them. From those items, I want to create a list of Orders. Some items will have the same OrderId so I want to try to group by OrderId. I then want to sort by date. Here's what I have so far: Public ReadOnly Property AllOrders() As List(Of Order) Get Return Items.Select(Function(i As MyItem) New Order(i.OrderID)) _ .GroupBy(Function(o As Order) New Order(o.OrderID)) _ .OrderBy(Function(o As Order) o.DateOrdered).ToList End Get End Property This, of course, doesn't compile, and I get the error: Value of type 'System.Collections.Generic.List(Of System.Linq.IGrouping(Of Order, Order))' cannot be converted to 'System.Collections.Generic.List(Of Order))' I've bolded the part where I think the problem is, but I have no idea how to fix it. Also, it used to work fine (except there were duplicate values) before I added the .GroupBy statement. Anyone have any ideas? Thanks

• Some questions about slugs in ASP.NET MVC content system

  - by mare

  In my application I'm currently using forms which allow to enter Title and Slug fields. Now I've been struggling with the slugs thing for a while because I can never decide once and for all how to handle them. 1) Make Title and Slug indenpendent Should I allow users to enter both Title and Slug separetely? This is what I had first. I also had an option that if user did not enter the Slug it was derived from the Title. If both were enter, the Slug field took precedence. 2) Derive Slug from Title, when content is inserted that's it for the Slug, no more changes Then, I switched to only Title field and derive Slug from title. While doing it I found out that now I have to change all the forms that allowed user to enter a slug. This way of doing it also prevents users to change Slugs - they can change the Title but it has no effect on the Slug. You can think of it like Slug is uniqued ID. 3) Now I'm thinking again of allowing users to change slug Though I don't think it is all that useful. How many times does the content that someone already added, spent time on writing it, even require a change of either Title or slug? I don't think it is that many times. The biggest problem with the 3rd option is that If I use Slugs as IDs, I need to update the reference all over the place when Slug changes. Or maintain a table that would contain somekind of Slug history. What are you thoughts on these, I hope, valid questions?

• Handling Model Inheritance in ASP.NET MVC2 & NHibernate

  - by enth

  I've gotten myself stuck on how to handle inheritance in my model when it comes to my controllers/views. Basic Model: public class Procedure : Entity { public Procedure() { } public int Id { get; set; } public DateTime ProcedureDate { get; set; } public ProcedureType Type { get; set; } } public ProcedureA : Procedure { public double VariableA { get; set; } public int VariableB { get; set; } public int Total { get; set; } } public ProcedureB : Procedure { public int Score { get; set; } } etc... many of different procedures eventually. So, I do things like list all the procedures: public class ProcedureController : Controller { public virtual ActionResult List() { IEnumerable<Procedure> procedures = _repository.GetAll(); return View(procedures); } } but now I'm kinda stuck. Basically, from the list page, I need to link to pages where the specific subclass details can be viewed/edited and I'm not sure what the best strategy is. I thought I could add an action on the ProcedureController that would conjure up the right subclass by dynamically figuring out what repository to use and loading the subclass to pass to the view. I had to store the class in the ProcedureType object. I had to create/implement a non-generic IRepository since I can't dynamically cast to a generic one. public virtual ActionResult Details(int procedureID) { Procedure procedure = _repository.GetById(procedureID, false); string className = procedure.Type.Class; Type type = Type.GetType(className, true); Type repositoryType = typeof (IRepository<>).MakeGenericType(type); var repository = (IRepository)DependencyRegistrar.Resolve(repositoryType); Entity procedure = repository.GetById(procedureID, false); return View(procedure); } I haven't even started sorting out how the view is going to determine which partial to load to display the subclass details. I'm wondering if this is a good approach? This makes determining the URL easy. It makes reusing the Procedure display code easy. Another approach is specific controllers for each subclass. It simplifies the controller code, but also means many simple controllers for the many procedure subclasses. Can work out the shared Procedure details with a partial view. How to get to construct the URL to get to the controller/action in the first place? Time to not think about it. Hopefully someone can show me the light. Thanks in advance.

• asp.net detailsview update method not getting new values

  - by Ali

  Hi all, I am binding a detailsview with objectdatasource which gets the select parameter from the querystring. The detailsview shows the desired record, but when I try to update it, my update method gets the old values for the record (and hence no update). here is my detailsview code: <asp:DetailsView ID="dvUsers" runat="server" Height="50px" Width="125px" AutoGenerateRows="False" DataSourceID="odsUserDetails" onitemupdating="dvUsers_ItemUpdating"> <Fields> <asp:CommandField ShowEditButton="True" /> <asp:BoundField DataField="Username" HeaderText="Username" SortExpression="Username" ReadOnly="true" /> <asp:BoundField DataField="FirstName" HeaderText="First Name" SortExpression="FirstName" /> <asp:BoundField DataField="LastName" HeaderText="Last Name" SortExpression="LastName" /> <asp:BoundField DataField="Email" runat="server" HeaderText="Email" SortExpression="Email" /> <asp:BoundField DataField="IsActive" HeaderText="Is Active" SortExpression="IsActive" /> <asp:BoundField DataField="IsOnline" HeaderText="Is Online" SortExpression="IsOnline" ReadOnly="true" /> <asp:BoundField DataField="LastLoginDate" HeaderText="Last Login" SortExpression="LastLoginDate" ReadOnly="true" /> <asp:BoundField DataField="CreateDate" HeaderText="Member Since" SortExpression="CreateDate" ReadOnly="true" /> <asp:TemplateField HeaderText="Membership Ends" SortExpression="ExpiryDate"> <EditItemTemplate> <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("ExpiryDate") %>'></asp:TextBox> <cc1:CalendarExtender ID="TextBox1_CalendarExtender" runat="server" Enabled="True" TargetControlID="TextBox1"> </cc1:CalendarExtender> </EditItemTemplate> <InsertItemTemplate> <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("ExpiryDate") %>'></asp:TextBox> </InsertItemTemplate> <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%# Bind("ExpiryDate") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> </Fields> and here is the objectdatasource code: <asp:ObjectDataSource ID="odsUserDetails" runat="server" SelectMethod="GetAllUserDetailsByUserId" TypeName="QMS_BLL.Membership" UpdateMethod="UpdateUserForClient"> <UpdateParameters> <asp:Parameter Name="User_ID" Type="Int32" /> <asp:Parameter Name="firstName" Type="String" /> <asp:Parameter Name="lastName" Type="String" /> <asp:SessionParameter Name="updatedByUser" SessionField="userId" DefaultValue="1" /> <asp:Parameter Name="expiryDate" Type="DateTime" /> <asp:Parameter Name="Email" Type="String" /> <asp:Parameter Name="isActive" Type="String" /> </UpdateParameters> <SelectParameters> <asp:QueryStringParameter DefaultValue="1" Name="User_ID" QueryStringField="User_ID" Type="Int32" /> </SelectParameters> </asp:ObjectDataSource> Is the OnItemUpdating method still required when you have your custom BLL method called on insertevent? (which is being executed fine in my case but updating with the old values) or am I missing something else? Also I tried to provide an OnItemUpdating method and in there I tried to capture the contents of the textboxes (the new values). I got an exception: "Specified argument was out of the range of valid values. Parameter name: index" when I tried to do: TextBox txtFirstName = (TextBox)dvUsers.Rows[1].Cells[1].Controls[0]; Any help will be most appreciated.

• Selected Item in Dropdown Lists from Enum in ASP.net MVC

  - by AlexCuse

  Sorry if this is a dup, my searching turned up nothing. I am using the following method to generate drop down lists for enum types (lifted from here: http://addinit.com/?q=node/54): public static string DropDownList(this HtmlHelper helper, string name, Type type, object selected) { if (!type.IsEnum) throw new ArgumentException("Type is not an enum."); if(selected != null && selected.GetType() != type) throw new ArgumentException("Selected object is not " + type.ToString()); var enums = new List<SelectListItem>(); foreach (int value in Enum.GetValues(type)) { var item = new SelectListItem(); item.Value = value.ToString(); item.Text = Enum.GetName(type, value); if(selected != null) item.Selected = (int)selected == value; enums.Add(item); } return System.Web.Mvc.Html.SelectExtensions.DropDownList(helper, name, enums, "--Select--"); } It is working fine, except for one thing. If I give the dropdown list the same name as the property on my model the selected value is not set properly. Meaning this works: <%= Html.DropDownList("fam", typeof(EnumFamily), Model.Family)%> But this doesn't: <%= Html.DropDownList("family", typeof(EnumFamily), Model.Family)%> Because I'm trying to pass an entire object directly to the controller method I am posting to, I would really like to have the dropdown list named for the property on the model. When using the "right" name, the dropdown does post correctly, I just can't seem to set the selected value. I don't think this matters but I am running MVC 1 on mono 2.6

• Binary to strings as binary? C #/.NET

  - by acidzombie24

  Redis keys are binary safe. I'd like to mess around and put binary into redis using C#. My client of choice doesn't support writing binary keys it uses keys and it make sense. However i am just fooling around so tell me how i can do this. How do i convert a raw byte[] into a string? At first i was thinking about converting a byte[] to a utf8 string however unicode has some checks to see if its valid or not. So raw binary should fail. Actually i tried it out. Instead of failing i got a strange result. My main question is how do i convert a raw byte[] to the equivalent string? My unimportant question is why did i get a 512 byte string instead of an exception saying this is not a valid UTF8 string? code var rainbow = new byte[256]; for (int i = 0; i < 256; i++) { rainbow[i] = (byte)i; } var sz = Encoding.UTF8.GetString(rainbow); var szarr = Encoding.UTF8.GetBytes(sz); Console.WriteLine("{0} {1} {2}", ByteArraysEqual(szarr, rainbow), szarr.Length, rainbow.Length); Output False 512 256

• ASP.NET MVC: what mechanic returns ViewModel objects?

  - by Dr. Zim

  As I understand it, Domain Models are classes that only describe the data (aggregate roots). They are POCOs and do not reference outside libraries (nothing special). View models on the other hand are classes that contain domain model objects as well as all the interface specific objects like SelectList. A ViewModel includes using System.Web.Mvc;. A repository pulls data out of a database and feeds them to us through domain model objects. What mechanic or device creates the view model objects, populating them from a database? Would it be a factory that has database access? Would you bleed the view specific classes like System.Web.Mvc in to the Repository? Something else? For example, if you have a drop down list of cities, you would reference a SelectList object in the root of your View Model object, right next to your DomainModel reference: public class CustomerForm { public CustomerAddress address {get;set;} public SelectList cities {get;set;} } The cities should come from a database and be in the form of a select list object. The hope is that you don't create a special Repository method to extract out just the distinct cities, then create a redundant second SelectList object only so you have the right data types.
