• Enterprise library not responding.

  - by Costa

  Hi I spent a day trying to make Ent Lib Logging work and log anything into database or event log, I have a web application and console application withe the same Ent Lib config, only the console is capable to log into the Event Log, I tried everything with permissions, but I don't know what exactly I am doing, which services should have what, It does not work!! HELP This is the config file which is automatically generated from Ent Lib utility and it works only on App.config, not on web.config <loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="General" logWarningsWhenNoCategoriesMatch="true" revertImpersonation="false"> <listeners> <add source="Logger" formatter="Text Formatter" log="Application" machineName="" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.FormattedEventLogTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" traceOutputOptions="None" filter="All" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.FormattedEventLogTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Formatted EventLog TraceListener" /> </listeners> <formatters> <add template="Timestamp: {timestamp}&#xD;&#xA;Message: {message}&#xD;&#xA;Category: {category}&#xD;&#xA;Priority: {priority}&#xD;&#xA;EventId: {eventid}&#xD;&#xA;Severity: {severity}&#xD;&#xA;Title:{title}&#xD;&#xA;Machine: {machine}&#xD;&#xA;Application Domain: {appDomain}&#xD;&#xA;Process Id: {processId}&#xD;&#xA;Process Name: {processName}&#xD;&#xA;Win32 Thread Id: {win32ThreadId}&#xD;&#xA;Thread Name: {threadName}&#xD;&#xA;Extended Properties: {dictionary({key} - {value}&#xD;&#xA;)}" type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Text Formatter" /> </formatters> <categorySources> <add switchValue="All" name="General"> <listeners> <add name="Formatted EventLog TraceListener" /> </listeners> </add> </categorySources> <specialSources> <allEvents switchValue="All" name="All Events" /> <notProcessed switchValue="All" name="Unprocessed Category" /> <errors switchValue="All" name="Logging Errors &amp; Warnings"> <listeners> <add name="Formatted EventLog TraceListener" /> </listeners> </errors> </specialSources> </loggingConfiguration> thanks

• IEnumerable not null but calling Count() results in Exception

  - by Draak

  I have code that's working beautifully on my development machine, but when deployed to the server is throwing null reference exception. So, I can't step through the code, but I've pinned down the culprit. But now I am puzzled. Here's the code. The question is below. Dim certs = From p In persons _ Select New Certificate( _ p.Value, _ New CertificateData.Seminar(thisEvent.Seminar.Name, _ thisEvent.StartDate.Value, _ thisEvent.EndDate.Value, _ thisEvent.Venue.City, _ thisEvent.Venue.State, _ New CertificateData.Instructor( _ staffMember.Name, _ staffMember.Titles, _ instrSignatPath))) _ With {.CertificateId = p.Key} lblMessage.Text = CStr(certs Is Nothing) lblMessage.Text = lblMessage.Text + "<br />" + CStr(certs.Count()) In the code above persons is a dictionary of custom class, and certs is of IEnumerable type. Now here's the quandary.. The first line that sets the label returns False, so certs is not null. But the second line throws an null reference exception. How is this possible?

• Amazon EC2 multiple servers share session state

  - by Theofanis Pantelides

  Hi everyone, I have a bunch of EC2 servers that are load balanced. Some of the servers are not sharing session, and users keep getting logged in and out. How can I make all the server share the one session, possibly even using a partitionresolver solution public class PartitionResolver : System.Web.IPartitionResolver { private String[] partitions; public void Initialize() { // create the partition connection string table // web1, web2 partitions = new String[] { "192.168.1.1" }; } public String ResolvePartition(Object key) { String oHost = System.Web.HttpContext.Current.Request.Url.Host.ToLower().Trim(); if (oHost.StartsWith("10.0.0") || oHost.Equals("localhost")) return "tcpip=127.0.0.1:42424"; String sid = (String)key; // hash the incoming session ID into // one of the available partitions Int32 partitionID = Math.Abs(sid.GetHashCode()) % partitions.Length; return ("tcpip=" + partitions[partitionID] + ":42424"); } } -theo

• MVC Model Binding to a collection where collection does not begin with a 0 index

  - by FloatLeft

  I'm trying to perform remote validation on a property of an item within a collection. The validation works OK on the first item of the collection. The http request to the validation method looks like: /Validation/IsImeiAvailable?ImeiGadgets[0].ImeiNumber=123456789012345 However on the 2nd item where the url looks like below, the validation doesn't work /Validation/IsImeiAvailable?ImeiGadgets[1].ImeiNumber=123456789012345 Now I'm pretty sure the reason for this, is that binding wont work on a collection that doesn't begin with a zero index. My validation method has a signature as below: public JsonResult IsImeiAvailable([Bind(Prefix = "ImeiGadgets")] Models.ViewModels.ImeiGadget[] imeiGadget) Because I'm passing an item within a collection I have to bind like this yet what I'm really passing is just a single value. Is there anyway I can deal with this other than just binding it as a plain old query string. Thanks Edit: This is the quick fix to get the Imei variable but I'd rather use the model binding: string imeiNumber = Request.Url.AbsoluteUri.Substring(Request.Url.AbsoluteUri.IndexOf("=")+1);

• I need to convert the result of a stored procedure in a dbml file to IQueryable to view a list in an

  - by RJ

  I have a MVC project that has a Linq to SQL dbml class. It is a table called Clients that houses client information. I can easily get the information to display in a View using the code I followed in Nerd Dinner but I have added a stored procedure to the dbml and it's result set is of IQueryable, not IQueryable. I need to convert IQueryable to IQueryable so I can display it in the same View. The reason for the sproc is so I can pass a search string tothe sproc and return the same information as a full list but filtered on the search. I know I can use Linq to filter the whole list but I don't want the whole list so I am using the sproc. Here is the code in my ClientRepository with a comment where I need to convert. What code goes in the commented spot. public IQueryable<Client> SelectClientsBySearch(String search) { IQueryable<SelectClientsBySearchResult> spClientList = (from p in db.SelectClientsBySearch(search) select p).AsQueryable(); //what is the code to convert IQueryable<SelectClientsBySearchResult> to IQueryable<Client> return clientList; }

• Object reference not set to an instance of an object.....?

  - by jamal

  Hi guys I always got this error from my site and it keeps bugging me.I've been trying to figure out the cause of this error but I can't really figure it out. Here's the stacktrace: at BasePage.Page_PreInit(Object sender, EventArgs e) at System.EventHandler.Invoke(Object sender, EventArgs e) at System.Web.UI.Page.OnPreInit(EventArgs e) at System.Web.UI.Page.PerformPreInit() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) And on my basepage I only got this code: Imports Microsoft.VisualBasic Public Class BasePage Inherits System.Web.UI.Page Private Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit Page.Theme = "Something" If (Request.UserAgent.IndexOf("AppleWebKit") 0) Then Request.Browser.Adapters.Clear() End If End Sub Private Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender If Me.Title = "Untitled Page" Then Throw New Exception("Page title cannot be ""Untitled Page"".") End If End Sub End Class According to the stacktrace this always happens on my basepage preinit event.What do you think is the problem here guys?

• MVC3 View For Loop values initialization

  - by Ryan

  So I have a for loop in my View that is supposed to render out the input boxes. Now inside these input boxes I want to put lables that disappear when you click on them. This is all simple. Now it's probably because my brain was wired for php first, and it has been difficult to get it to think in lambdas and object orientation, but I can't figure out how to do this: @{ for (int i = 0; i < 3; i++) { <div class="editor-label grid_2">User</div> Model.Users[i].UserFirstName = "First Name"; Model.Users[i].UserLastName = "Last Name"; Model.Users[i].UserEmailAddress = "Email Address"; <div class="grid_10"> @Html.TextBoxFor(m => Model.Users[i].UserFirstName, new { @class = "user-input" }) @Html.TextBoxFor(m => Model.Users[i].UserLastName, new { @class = "user-input" }) @Html.TextBoxFor(m => Model.Users[i].UserEmailAddress, new { @class = "user-input-long" }) @Html.CheckBoxFor(m => Model.Users[i].IsUserAdmin) <span>&nbsp;admin?</span> </div> <div class="clear"> </div> } } And initialize the values for the users. And you're probably thinking "Of course that won't work. You're going to get a Null Reference Exception", and you would be correct. I might need to initialize them somewhere else and I don't realize it but I'm just not sure. I've tried the [DefaultValue("First Name")] route and that doesn't work. I'm probably thinking about this wrong, but my brain is already shot from trying to figure out how to wire up these events to the controller, so any help would be appreciated!

• Custom authorize using MVC

  - by Karsten

  Im working a bit with MVC. I need to know something about roles when using the same controller for several users getting and showing pictures. I need to show pictures, but sometimes these pictures should only be shown for those who created them. So now when using the Authorize attribute and if picture and username match thrue my databse I could ofcause use this to make a match. I could ofcause make a match method in the controller. [Authorize] controllGetPicture(Picture ID){ getSomepicture.. return picture } DB relations Relations [User] <- [Pictures] ID FK_UserID Im thinking about just getting the User ID and compare with the Picture FK_UserId at the picture but I think it could be smarter. How?

• xUnit false positive when comparing null terminated strings

  - by mr.b

  I've come across odd behavior when comparing strings. First assert passes, but I don't think it should.. Second assert fails, as expected... [Fact] public void StringTest() { string testString_1 = "My name is Erl. I am a program\0"; string testString_2 = "My name is Erl. I am a program"; Assert.Equal<string>(testString_1, testString_2); Assert.True(testString_1.Equals(testString_2)); } Any ideas?

• Does HttpWebRequest automatically take care of certificate validation?

  - by Kevin Pang

  I'm using an HttpWebRequest object to access a web service via an HTTP POST. Part of the requirement is that I: Verify that the URL in the certificate matches the URL I'm posting to Verify that the certificate is valid and trusted Verify that the certificate has not expired Does HttpWebRequest automatically handle that for me? I'd assume that if any of these conditions came up, I'd get the standard "could not establish trust relationship for the SSL/TLS secure channel" exception.

• When are predicates appropriate and what is the best pattern for usage

  - by Maxim Gershkovich

  When are predicates appropriate and what is the best pattern for usage? What are the advantages of predicates? It seems to me like most cases where a predicate can be employed a tight loop would accomplish the same functionality? I don’t see a reusability argument given you will probably only implement a predicate in one method right? They look and feel nice but besides that they seem like you would only employ them when you need a quick hack on the collection classes? UPDATE But why would you be rewriting the tight loop again and again? In my mind/code when it comes to collections I always end up with something like Class Person End Class Class PersonList Inherits List(Of Person) Function FindByName(Name) as Person tight loop.... End Function End Class @Ani By that same logic I could implement the method as such Class PersonList Inherits List(Of Person) Function FindByName(Name) as PersonList End Function Function FindByAge(Age) as PersonList End Function Function FindBySocialSecurityNumber(SocialSecurityNumber) as PersonList End Function End Class And call it as such Dim res as PersonList = MyList.FindByName("Max").FindByAge(25).FindBySocialSecurityNumber(1234) and the result along with the amount of code and its reusability is largely the same, no? I am not arguing just trying to understand.

• Clearing Session in Global Application_Error

  - by Zarigani

  Whenever an unhandled exception occurs on our site, I want to: Send a notification email Clear the user's session Send the user to a error page ("Sorry, a problem occurred...") The first and last I've had working for a long time but the second is causing me some issues. My Global.asax.vb includes: Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs) ' Send exception report Dim ex As System.Exception = Nothing If HttpContext.Current IsNot Nothing AndAlso HttpContext.Current.Server IsNot Nothing Then ex = HttpContext.Current.Server.GetLastError End If Dim eh As New ErrorHandling(ex) eh.SendError() ' Clear session If HttpContext.Current IsNot Nothing AndAlso HttpContext.Current.Session IsNot Nothing Then HttpContext.Current.Session.Clear() End If ' User will now be sent to the 500 error page (by the CustomError setting in web.config) End Sub When I run a debug, I can see the session being cleared, but then on the next page the session is back again! I eventually found a reference that suggests that changes to session will not be saved unless Server.ClearError is called. Unfortunately, if I add this (just below the line that sets "ex") then the CustomErrors redirect doesn't seem to kick in and I'm left with a blank page? Is there a way around this?

• Access parent class from custom attribute

  - by madcapnmckay

  Hi, Is it possible to access a parent class from within an attribute. For example I would like to create a DropDownListAttribute which can be applied to a property of a viewmodel class in MVC and then create a drop down list from an editor template. I am following a similar line as Kazi Manzur Rashid here. He adds the collection of categories into viewdata and retrieves them using the key supplied to the attribute. I would like to do something like the below, public ExampleDropDownViewModel { public IEnumerable<SelectListItem> Categories {get;set;} [DropDownList("Categories")] public int CategoryID { get;set; } } The attribute takes the name of the property containing the collection to bind to. I can't figure out how to access a property on the parent class of the attribute. Does anyone know how to do this? Thanks

• Cannot open a SQL2000 DTS package I imported into SQL2008

  - by RJ

  I am running into a problem trying to open a SQL2000 DTS package I imported into SQL2008. I set up a new server and installed a fresh install of SQL2008. The database I need to run is a SQL2000 database. I moved the database over with no problem but there are a few DTS packages that need to run in legacy on SQL2008. I exported the DTS packages I need out of SQL2000 and imported them successfully into SQL2008. My SQL2008 server is x64. I can see the DTS packages under Data Transformation Service in Legacy but when I try to open the package I get this message. "SQL Server 2000 DTS Designer components are required to edit DTS packages. Install the special web download, "SQL Server 2000 DTS Designer components" to use this feature. (Microsoft.SqlServer.DtsObjectExplorerUI)" I downloaded the components and installed them and still get this error. I researched and found an article about this not working on x64 so I have an x86 machine that I installed the SQL2008 tools and tried to open the package from there and got the same error. I have spent days on this and need help. Has anyone run across this and can tell me what to do. If you have solved this problem, please help me out. Thanks.

• Quick questions re moving to InfoPath forms

  - by sweissman

  Hi there: I’ve been asked to look into how best to move forms into InfoPath and have a couple of basic questions about your experiences so I can get an insider’s lay of the land. Even some short, quick bullets would be really helpful -- thank you! Are you starting from scratch in InfoPath, or are you converting from paper or a different e-format? (Jetform, PDF, etc.) Are you trying to re-create the layout of a specific paper form, or is a regular online form OK? (trying to learn what the latest thinking is about this) Do you need only simple fill and submit capabilities, or do you need programming for calculations, validation, database lookup/entry/reporting, etc. as well? (don’t know how much harder it is to do all this vs. not) How long does each form take to finish? (I know it depends, but is there a rough guideline for planning purposes?) Who’s doing the actual work? (by title or function) What is especially straightforward or challenging about moving to InfoPath forms? (forewarned is forearmed!)
