  • if all my views are passed a strongly typed viewdata, if they have a baseviewdata class, can I set a

    - by Blankman
    I want all my views to inherit from a baseview data so I can set some shared properties that all my views will need. Can I set some properties in OnExecuting so I don't have to do it for all Actions? I want to then display the string value of the property in all my view pages. If yes, how can I do this? I need to hook into the base view data somehow? so i'll have: public MyViewData : ViewData { } And I need one for generics also?

  • Form with list of checkboxes (best practices)

    - by boris callens
    I have a view that allows the user to make a selection from an IEnumerable. The way I'm doing it now is to give each checkbox the id of the item and work with the form collection at the controller's side. I seem to remember there to be a better way but can't remember how anymore. Are there any better practices?

  • Session_End Alternatives

    - by grimus
    I have seen in some other questions that using Session_ End() in Global.asax.cs is not advised. This is because if you're not using the default Session handler, Session_End won't get called, correct? Is there any other cases where it won't get called? The big question is: If you can't depend on Session_End(), what do you do to determine when a session has closed?

  • Is MSDN referencing a system.thread, a worker thread, an io thread or all three?

    - by w0051977
    Please see the warning below taken from the StreamWriter class specification (http://msdn.microsoft.com/en-us/library/system.io.streamwriter.aspx): "Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe." I understand that a W3WC process contains two thread pools i.e. worker threads and I/O threads. A worker thread could contain many threads of its own (if the application creates its own System.Thread instances). Does the warning only relate to System.Threads or does it relate to worker threads and I/O threads as well I.e. as the instance variables of the streamwriter class are not thread safe then does this mean that there would be problems if multiple worker threads access it eg if two users on two different web clients attempt to write to the log file at the same time, then could one lock out the other?

  • Session vs singleton pattern

    - by chobo
    Hi, I have a web application where I would like to pull user settings from a database and store them for Global access. Would it make more sense to store the data in a Singleton, or a Session object? What's the difference between the two? Is it better to store the data as an object reference or break it up into value type objects (ints and strings)? Thanks!

  • Making A Dynaically Created Excel Report Downloadable

    - by Nick LaMarca
    I have 2 blocks of code, if someone could help me put them together I would get the functionality I am looking for. The first block of code downloads a gridview to excel using the download dialog I am looking for: Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control) ' Verifies that the control is rendered End Sub Private Sub ExportToExcel(ByVal filename As String, ByVal gv As GridView, ByVal numOfCol As Integer) Response.Clear() Response.Buffer = True Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", filename)) Response.Charset = "" Response.ContentType = "application/vnd.ms-excel" Dim sw As New StringWriter() Dim hw As New HtmlTextWriter(sw) gv.AllowPaging = False gv.DataBind() 'Change the Header Row back to white color gv.HeaderRow.Style.Add("background-color", "#FFFFFF") For i As Integer = 0 To numOfCol - 1 gv.HeaderRow.Cells(i).Style.Add("background-color", "blue") gv.HeaderRow.Cells(i).Style.Add("color", "#FFFFFF") Next For i As Integer = 0 To gv.Rows.Count - 1 Dim row As GridViewRow = gv.Rows(i) 'Change Color back to white row.BackColor = System.Drawing.Color.White For j As Integer = 0 To numOfCol - 1 row.Cells(j).Style.Add("text-align", "center") Next 'Apply text style to each Row row.Attributes.Add("class", "textmode") 'Apply style to Individual Cells of Alternating Row If i Mod 2 <> 0 Then For j As Integer = 0 To numOfCol - 1 row.Cells(j).Style.Add("background-color", "#CCFFFF") row.Cells(j).Style.Add("text-align", "center") '#C2D69B 'row.Cells(j).Style.Add("font-size", "12pt") Next End If Next gv.RenderControl(hw) 'style to format numbers to string Dim style As String = "<style> .textmode { mso-number-format:\@; } </style>" Response.Write(style) Response.Output.Write(sw.ToString()) Response.Flush() Response.End() End Sub The second block of code is a sample report I am wish to be downloaded. So instead of downloading a gridview I want this function to accept a worksheet object.

  • When should I implement IDisposeable?

    - by Bobby
    What is the best practice for when to implement IDisposeable? Is the best rule of thumb to implement it if you have one managed object in the class, or does it depend if the object was created in the class or just passed in? Should I also do it for classes with no managed objects at all?

  • How to use RedirectToAction to redirect to the default action of different controller?

    - by atbebtg
    I am trying to do a RedirectToAction from http://mywebsite/Home/ using the following code: return RedirectToAction("Index","Profile", new { id = formValues["id"] }); The above code will succesfully take me to http://mywebsite/Profile/Index/223224 What do I have to do to make it redirect to http://mywebsite/Profile/223224 Thank you. I figured out how to do this. First I have to add custom route rule: routes.MapRoute("Profile", "Profile/{id}", new { controller = "Profile", action = "Index", id = UrlParameter.Optional }); Then I can do the following: [AcceptVerbs(HttpVerbs.Post)] public RedirectResult Index(FormCollection formValues) { return Redirect("~/Survey/" + formValues["Id"]); }

  • Corrupt output with an HttpModule

    - by clementi
    I have an HttpModule that looks at the query string for a parameter called "cmd" and executes one of a small set of predefined commands that display server stats in XML. For example, http://server01?cmd=globalstats. Now, on rare occasions, like once out of hundreds of times, I will get corrupt output like this: <!-- the stats start displaying fine... --> <stats> <ServerName>SERVER01</ServerName> <StackName>Search</StackName> <TotalRequests>945</TotalRequests> <!-- ...until something has gone awry and now we're getting the markup of the home page! --> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> ...the rest of the home page markup... (Remove the comments in the example above.) I'm not all that familiar with HttpModules and the IIS pipeline, but could this be a threading problem? Or, what else?

  • Gridview inside UpdatePanel refresh

    - by Attilah
    I use a GridView to represent data from a table in my DB. the GridView has some template fields whose content are determined before displaying the Grid ( I use the RowDataBound event to determine content of template fields before displaying the GridView). The page displays a list of records from the table records and then, the recording process starts. after the process is over, the template fields should be updated. how do I automatically refresh the GridView after the process is finished ? it should be noted that the GridView is contained within an control and that I continuously poll the server using a Timer control that executes "GridView1.DataBind()" at the server level every 60 seconds. since the GridView is inside an UpdatePanel, calling DataBind() method on it doesn't seem to call the RowDataBound event. How can I solve this ?

  • Get information from a higher class?

    - by Clint Davis
    I don't know really how to word the question so please bear with me... I have 3 classes: Server, Database, and Table. Each class has a "Name" property. How I want it to work is that each server can have multiple databases and each database can have multiple tables. So in the Server class I have this property. Private _databases As List(Of Database) Public Property Databases() As List(Of Database) Get Return _databases End Get Set(ByVal value As List(Of Database)) _databases = value End Set End Property And I have something similar in the Database class for the tables. This works fine now because I can do something like this to get all the databases in the server. For Each db In s.Databases 's being the server object Debug.Print(db.Name) Next I would like to expand these classes. I want the server class to handle all the connection information and I would like the other classes to use the server class's connection information in them. For example, I setup a server class and set the connection string to the server. Then I want the database class to use serverclass.connectionstring property to connect to the server and get a list of all the databases. But I want to keep that code in the database class. How can I do this? I've attached some code of what I want to do. Public Class Server Private _name As String Public Property Name() As String Get Return _name End Get Set(ByVal value As String) _name = value End Set End Property Private _databases As List(Of Database) Public Property Databases() As List(Of Database) Get Return _databases End Get Set(ByVal value As List(Of Database)) _databases = value End Set End Property End Class '-----New class Public Class Database Private _name As String Public Property Name() As String Get Return _name End Get Set(ByVal value As String) _name = value End Set End Property Private _tables As List(Of Table) Public Property Tables() As List(Of Table) Get Return _tables End Get Set(ByVal value As List(Of Table)) _tables = value End Set End Property 'This is where I need help! Private Sub LoadTables () dim connectionstring as string = server.connectionstring 'Possible? 'Do database stuff End Class Thanks for reading!

  • Raise differing beeps

    - by themaninthesuitcase
    I need to be able to raise different types of audio notifications to the user. I need an "ok" and an "error" type sounds, I was hoping to be able to raise a simple beep and a critical stop type sound but I can only find the Beep() command which doesn't allow for differing sounds. Is there a library that does what I need or will I need to roll my own using the system wavs.

  • Choose between multiple options with defined probability

    - by Sijin
    I have a scenario where I need to show a different page to a user for the same url based on a probability distribution, so for e.g. for 3 pages the distribution might be page 1 - 30% of all users page 2 - 50% of all users page 3 - 20% of all users When deciding what page to load for a given user, what technique can I use to ensure that the overall distribution matches the above? I am thinking I need a way to choose an object at "random" from a set X { x1, x2....xn } except that instead of all objects being equally likely the probability of an object being selected is defined beforehand.

  • Passing derived objects in a constructure

    - by Clarence Klopfstein
    This is a bit of a convoluted question, hopefully I can make it clear. I am finding that this may not be possible, but am trying to see if anybody has a solution. I have four classes, two are core classes and two are those core classes extended: extUser Extends coreUser extSecurity Extends coreSecurity In the constructor for coreUser you have this: public coreUser(string id, ref coreSecurity cs) When trying to extend coreUser you would have this: public extUser(string id ref extSecurity es) : base(id, ref es) This fails because es is of type, extSecurity and the base class expects a type of coreSecurity. I've not found anyway to cast this to allow for me to override this base class in C#. In VB it works just fine. Ideas?
