• How do you ensure a mimetype in asp.net?

  - by Sem Dendoncker

  Hello, I have the following code to export a zip file: byte[] buffer = FileUtil.FileToByteArray(zipLocation, true); // push the memory data to the client. _ctx.Response.ContentType = "application/zip"; _ctx.Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", String.Format("map{0}.zip", mapId))); _ctx.Response.BinaryWrite(buffer); This code works great. After every export I get a perfectly made zipfile. The problem however is that when I try to import it, the mimetype sometimes is "application/empty". Now I wonder how can I ensure that the mimetype is always added? Cheers, M.

• Why is this consider bad practice? or is it? (ASP.Net)

  - by user318573

  Would this code be considered bad practice: <div id="sidebar"> <% =DisplayMeetings(12) %> </div> This is a snippet of code from the default.aspx of a small web app I have worked on. It works perfectly well, runs very fast, but as always, I am aware of the fact that just because it works, doesn't mean it is OK. Basically, the DisplayMeetings subroutine outputs a bunch of formatted HTML (an unordered list actually), with no formatting, just the requisite html, and then my CSS performs all the necessary formatting. The data for generating the list comes from an SQL server database (the parameter controls how many rows to return) and I am using stored procedures and datareader for fast access. This keeps my front-end extraordinary simple and clean, imho, and lets me do all the work in VB or C# in a separate module. I could of course use a databound repeater (and probably 6 or more other methods) of accomplishing the same thing, but are they any better? Other than loosing the design-time features of VS2010?

Is there a fast way to find all the solutions that contain ProjectD.csproj? I can open them one by one and see what they contain, but I would like a feature such as "find all the solutions containing this project".

• Is there a .Net StyleCop rule which warns about lock(this), lock(typeof, lock(<string obj>, etc.?

  - by Hamish Grubijan

  These 3 types of lock are apparently bad. What other type of locking is bad? Are there Stylecop / FxCop rules that would catch this? If not, then would you please help me with a custom rule implementation? They code for all of them must be similar, right? Thank you.

• ASP.NET - How can I cache user details for the duration of their visit?

  - by rockinthesixstring

  I've built a Repository that gets user details Public Function GetUserByOpenID(ByVal openid As String) As User Implements IUserRepository.GetUserByOpenID Dim user = (From u In dc.Users Where u.OpenID = openid Select u).FirstOrDefault Return user End Function And I'd like to be able to pull those details down IF the user is logged in AND IF the cached data is null. What is the best way to create a User object that contains all of the users details, and persist it across the entire site for the duration of their visit? I Was trying this in my Global.asax, but I'm not really happy using Session variables. I'd rather have a single object with all the details inside. Private Sub BaseGlobal_AcquireRequestState(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.AcquireRequestState If Session("UserName") Is Nothing AndAlso User.Identity.IsAuthenticated Then Dim repo As UrbanNow.Core.IUserRepository = New UrbanNow.Core.UserRepository Dim _user As New UrbanNow.Core.User _user = repo.GetUserByOpenID(User.Identity.Name) Session("UserName") = _user.UserName() Session("UserID") = _user.ID End If End Sub

• Why does the default view for a List in ASP.NET MVC use 'var' to iterate through the items?

  - by SLC

  The title pretty much sums it up, it puts the following line of code in: <% foreach (var item in Model) { %> As the View is auto-generated and uses reflection to work out exactly what item is, so you get intellisense and everything, I just wonder, why do they use var rather than the actual type?

• .NET grouping forms so that pulling up the primary form shows all other forms?

  - by toasteroven

  I have an app that can open up some other forms at the user's request, and they're set to not show in the taskbar. The problem is, if one of the secondary windows becomes hidden by another app, switching to the primary window only brings that form to the forefront. Is there a good way to "group" the forms so that giving any of them focus brings the whole group to the front? I tried calling BringToFront() on each form in the primary form's Activated event, but that also gives the secondary forms focus, making it impossible to interact with the primary form.

• Why is the new Tuple type in .Net 4.0 a reference type (class) and not a value type (struct)

  - by Bent Rasmussen

  Does anyone know the answer and/or have an oppinion about it? Since tuples would normally not be very large I would assume it would make more sense to use structs than classes for these. What say you?

• In C# or .NET, is there a way to prevent other threads from invoking methods on a particular thread?

  - by YWE

  I have a Windows Forms application with a BackgroundWorker. In a method on the main form, a MessageBox is shown and the user must click the OK button to continue. Meanwhile, while the messagebox is being displayed, the BackgroundWorker finishes executing and calls the RunWorkerCompleted event. In the method I have assigned to that event, which runs on the UI thread, the Close method is called on the form. Even though the method that shows the message box is still running, the UI thread is not blocking other threads from invoking methods on it. So the Close method gets called on the form. What I want is for the UI thread to block other threads' invokes until the method with the message box has finished. Is there an easy way to do that?

• How to Pass complex objects in ASP.NET MVC using Get parameters?

  - by VJ

  I am wanting to pass something like the following to my view from my controller via GET not POST: public class MyDTO { public string val1 { get; set; } public string val2 { get; set; } public MyObject obj { get; set; } } public class MyObject { public int SomeInt { get; set; } public string ACoolValue { get; set; } public string YetAnotherCoolValue { get; set; } } And then the controller would like like this. (Note it is a GET): public ActionResult MyView(MyDTO dto) { return View(dto) } The problem is that the instance of MyObject is coming back as null, where val1 and val2 have data. Has anyone run across this?
