• Moving monarchs and dragons: migrating the JDK bugs to JIRA

  - by darcy

  Among insects, monarch butterflies and dragonflies have the longest migrations; migrating JDK bugs involves a long journey as well! As previously announced by Mark back in March, we've been working according to a revised plan to transition the JDK bug management from Sun's legacy system to initially an Oracle-internal JIRA instance which is afterward made visible and usable externally. I've been busily working on this project for the last few months and the team has made good progress on many aspects of the effort: JDK bugs will be imported into JIRA regardless of age; bugs will also be imported regardless of state, including closed bugs. Consequently, the JDK bug project will start pre-populated with over 100,000 existing bugs, some dating all the way back to 1994. This will allow a continuity of information and allow new issues to be linked to old ones. Using a custom import process, the Sun bug numbers will be preserved in JIRA. For example, the Sun bug with bug number 4040458 will become "JDK-4040458" in JIRA. In JIRA the project name, "JDK" in our case, is part of the bug's identifier. Bugs created after the JIRA migration will be numbered starting at 8000000; bugs imported from the legacy system have numbers ranging between 1000000 and 79999999. We're working with the bugs.sun.com team to try to maintain continuity of the ability to both read JDK bug information as well as to file new incidents. At least for now, the overall architecture of bugs.sun.com will be the same as it is today: it will be a gateway bridging to an Oracle-internal system, but the internal system will change to JIRA from the legacy database. Generally we are aiming to preserve the visibility of bugs currently viewable on bugs.sun.com; however, bugs in areas not related to the JDK will not be visible after the transition to JIRA. New incoming incidents will be sent to a separate JIRA project for initial triage before possibly being moved into the JDK project. JDK bug management leans heavily on being able to track the state of bugs in multiple releases, especially to coordinate delivering synchronized security releases (known as CPUs, critital patch updates, in Oracle parlance). For a security release, it is common for half a dozen or more release trains to be affected (for example, JDK 5, JDK 6 update, OpenJDK 6, JDK 7 update, JDK 8, virtual releases for HotSpot express, etc.). We've determined we need to track at least the tuple of (release, responsible engineer/assignee for the release, status in the release) for the release trains a fix is going into. To do this in JIRA, we are creating a separate port/backport issue type along with a custom link type to allow the multiple release information to be easily grouped and presented together. The Sun legacy system had a three-level classification scheme, product, category, and subcategory. Out of the box, JIRA only has a one-level classification, component. We've implemented a custom second-level classification, subcomponent. As part of the bug migration we've taken the opportunity to think about how bugs should be grouped under a two-level system and we'll the new system will be simpler and more regular. The main top-level components of the JDK product will include: core-libs client-libs deploy install security-libs other-libs tools hotspot For the libs areas, the primary name of the subcomportment will be the package of the API in question. In the core-libs component, there will be subcomponents like: java.lang java.lang.class_loading java.math java.util java.util:i18n In the tools component, subcomponents will primarily correspond to command names in $JDK/bin like, jar, javac, and javap. The first several bulk imports of the JDK bugs into JIRA have gone well and we're continuing to refine the import to have greater fidelity to the current data, including by reconstructing information not brought over in a structured fashion during the previous large JDK bug system migration back in 2004. We don't currently have a firm timeline of when the new system will be usable externally, but as it becomes available, I'll share further information in follow-up blog posts.

• Stepping outside Visual Studio IDE [Part 2 of 2] with Mono 2.6.4

  - by mbcrump

  Continuing part 2 of my Stepping outside the Visual Studio IDE, is the open-source Mono Project. Mono is a software platform designed to allow developers to easily create cross platform applications. Sponsored by Novell (http://www.novell.com/), Mono is an open source implementation of Microsoft's .NET Framework based on the ECMA standards for C# and the Common Language Runtime. A growing family of solutions and an active and enthusiastic contributing community is helping position Mono to become the leading choice for development of Linux applications. So, to clarify. You can use Mono to develop .NET applications that will run on Linux, Windows or Mac. It’s basically a IDE that has roots in Linux. Let’s first look at the compatibility: Compatibility If you already have an application written in .Net, you can scan your application with the Mono Migration Analyzer (MoMA) to determine if your application uses anything not supported by Mono. The current release version of Mono is 2.6. (Released December 2009) The easiest way to describe what Mono currently supports is: Everything in .NET 3.5 except WPF and WF, limited WCF. Here is a slightly more detailed view, by .NET framework version: Implemented C# 3.0 System.Core LINQ ASP.Net 3.5 ASP.Net MVC C# 2.0 (generics) Core Libraries 2.0: mscorlib, System, System.Xml ASP.Net 2.0 - except WebParts ADO.Net 2.0 Winforms/System.Drawing 2.0 - does not support right-to-left C# 1.0 Core Libraries 1.1: mscorlib, System, System.Xml ASP.Net 1.1 ADO.Net 1.1 Winforms/System.Drawing 1.1 Partially Implemented LINQ to SQL - Mostly done, but a few features missing WCF - silverlight 2.0 subset completed Not Implemented WPF - no plans to implement WF - Will implement WF 4 instead on future versions of Mono. System.Management - does not map to Linux System.EnterpriseServices - deprecated Links to documentation. The Official Mono FAQ’s Links to binaries. Mono IDE Latest Version is 2.6.4 That's it, nothing more is required except to compile and run .net code in Linux. Installation After landing on the mono project home page, you can select which platform you want to download. I typically pick the Virtual PC image since I spend all of my day using Windows 7. Go ahead and pick whatever version is best for you. The Virtual PC image comes with Suse Linux. Once the image is launch, you will see the following: I’m not going to go through each option but its best to start with “Start Here” icon. It will provide you with information on new projects or existing VS projects. After you get Mono installed, it's probably a good idea to run a quick Hello World program to make sure everything is setup properly. This allows you to know that your Mono is working before you try writing or running a more complex application. To write a "Hello World" program follow these steps: Start Mono Development Environment. Create a new Project: File->New->Solution Select "Console Project" in the category list. Enter a project name into the Project name field, for example, "HW Project". Click "Forward" Click “Packaging” then OK. You should have a screen very simular to a VS Console App. Click the "Run" button in the toolbar (Ctrl-F5). Look in the Application Output and you should have the “Hello World!” Your screen should look like the screen below. That should do it for a simple console app in mono. To test out an ASP.NET application, simply copy your code to a new directory in /srv/www/htdocs, then visit the following URL: http://localhost/directoryname/page.aspx where directoryname is the directory where you deployed your application and page.aspx is the initial page for your software. Databases You can continue to use SQL server database or use MySQL, Postgress, Sybase, Oracle, IBM’s DB2 or SQLite db. Conclusion I hope this brief look at the Mono IDE helps someone get acquainted with development outside of VS. As always, I welcome any suggestions or comments.

• How to Create SharePoint List and Insert List Item programmatically from a Windows Forms Application.

  - by Michael M. Bangoy

  In this post I’m going to demonstrate how to create SharePoint List and also Insert Items on the List from a Windows Forms Application. 1. Open Visual Studio and create a new project. On the project template select Windows Form Application under C#. 2. In order to communicate with Sharepoint from a Windows Forms Application we need to add the 2 Sharepoint Client DLL located in c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI.  3. Select the Microsoft.Sharepoint.Client.dll and Microsoft.Sharepoint.Client.Runtime.dll. (Your solution should look like the one below) 4. Open the Form1 in design view and from the Toolbox menu add a button on the form surface. Your form should look like the one below. 5. Double click the button to open the code view. Add Using statement to reference the Sharepoint Client Library then create method for the Create List. Your code should like the codes below. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Security; using System.Windows.Forms; using SP = Microsoft.SharePoint.Client; namespace ClientObjectModel {     public partial class Form1 : Form     {         // url of the Sharepoint site         const string _context = "urlofthesharepointsite";         public Form1()         {             InitializeComponent();         }         private void Form1_Load(object sender, EventArgs e)         {                    }         private void cmdcreate_Click(object sender, EventArgs e)         {             try             {                 // declare the ClientContext Object                 SP.ClientContext _clientcontext = new SP.ClientContext(_context);                 SP.Web _site = _clientcontext.Web;                 // declare a ListCreationInfo                 SP.ListCreationInformation _listcreationinfo = new SP.ListCreationInformation();                 // set the Title and the Template of the List to be created                 _listcreationinfo.Title = "NewListFromCOM";                 _listcreationinfo.TemplateType = (int)SP.ListTemplateType.GenericList;                 // Call the add method to the ListCreatedInfo                 SP.List _list = _site.Lists.Add(_listcreationinfo);                 // Add Description field to the List                 SP.Field _Description = _list.Fields.AddFieldAsXml(@"                                     <Field Type='Text'                                         DisplayName='Description'>                                     </Field>", true, SP.AddFieldOptions.AddToDefaultContentType);                 // declare the List item Creation object for creating List Item                 SP.ListItemCreationInformation _itemcreationinfo = new SP.ListItemCreationInformation();                 // call the additem method of the list to insert a new List Item                 SP.ListItem _item = _list.AddItem(_itemcreationinfo);                 _item["Title"] = "New Item from Client Object Model";                 _item["Description"] = "This item was added by a Windows Forms Application";                 // call the update method                 _item.Update();                 // execute the query of the clientcontext                 _clientcontext.ExecuteQuery();                 // dispose the clientcontext                 _clientcontext.Dispose();                 MessageBox.Show("List Creation Successfull");             }             catch(Exception ex)             {                 MessageBox.Show("Error creating list" + ex.ToString());             }          }     } } 6. Hit F5 to run the application. A message will be displayed on the screen if the operation is successful and also if it fails. 7. To make that the operation of our Windows Form Application has really created the List and Inserted an item on it. Let’s open our SharePoint site. Once the SharePoint is open click on the Site Actions then View All Site Content. 7. Click the List to open it and check if an Item is inserted. That’s it. Hope this helps.

• WiX, MSDeploy and an appealing configuration/deployment paradigm

  - by alexhildyard

  I do a lot of application and server configuration; I've done this for many years and have tended to view the complexity of this strictly in terms of the complexity of the ultimate configuration to be deployed. For example, specific APIs aside, I would tend to regard installing a server certificate as a more complex activity than, say, copying a file or adding a Registry entry.My prejudice revolved around the idea of a sequential deployment script that not only had the explicit prescription to apply a specific server configuration, but also made the implicit presumption that the server in question was in a good known state. Scripts like this fail for hundreds of reasons -- the Default Website didn't exist; the application had already been deployed; the application had already been partially deployed and failed to rollback fully, and so on. And so the problem is that the more complex the configuration activity, the more scope for error in any individual part of that activity, and therefore the greater the chance the server in question will not end up at exactly the desired configuration level.Recently I was introduced to a completely different mindset, which, for want of a better turn of phrase, I will call the "make it so" mindset. It's extremely simple both to explain and to implement. In place of the head-down, imperative script you used to use, you substitute a set of checks -- much like exception handlers -- around each configuration activity, starting with a check of the current system state. Thus the configuration logic becomes: "IF these services aren't started then start them, and IF XYZ website doesn't exist then create it, and IF these shares don't exist then create them, and IF these shares aren't permissioned in some particular way, then permission them so." This works. Really well, in my experience. Scenario 1: You want to get a system into a good known state; it's already in a good known state; you quickly realise there is nothing to do.Scenario 2: You want to get the system into a good known state; your script is flawed or the system is bust; it cannot be put into that state. You know exactly where (at least part of) the problem is and why.Scenario 3: You want to get the system into a good known state; people are fiddling around with the system just now. That's fine. You do what you can, and later you come back and try it againScenario 4: No one wants to deploy anything; they want you to prove that the previous deployment was successful. So you re-run the deployment script with the "-WhatIf" flag. It reports that there was nothing to change. There's your proof.I mentioned two technologies in the title -- MSI and MSDeploy. I am thinking specifically of the conversation that took place here. Having worked with both technologies, I think Rob Mensching's response is appropriately nuanced, and in essence the difference is this: sometimes your target is either to achieve a specific new server state, or to rollback to a known good one. Then again, your target may be to configure what you can, and to understand what you can't. Implicitly MSDeploy's "rollback" is simply to redeploy the previous version, whereas a well-crafted MSI will actively put your system into that state without further intervention. Either way, if all goes well it will leave you with a system in one of two states, whereas MSDeploy could leave your system in one of many states. The key is that MSDeploy and MSI are complementary technologies; which suits you best depends as much on Operational guidance as your Configuration remit.What I wanted to say was that I have always been for atomic, transactional-based configuration, but having worked with the "make it so" paradigm, I have been favourably impressed by the actual results. I'm tempted to put a more technical post up on this in due course.

• Intermittent PolicyException: Execution permission cannot be acquired.

  - by Aaron Maenpaa

  We are intermittently seeing the following exception shortly after an App Pool recycle in an ASP.NET application: System.Configuration.ConfigurationErrorsException: Could not load file or assembly 'Microsoft.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418) ---> System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418) File name: 'Microsoft.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' ---> System.Security.Policy.PolicyException: Execution permission cannot be acquired. at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Boolean checkExecutionPermission) at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Int32& securitySpecialFlags, Boolean checkExecutionPermission) at System.Reflection.Assembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection) at System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection) at System.Reflection.Assembly.InternalLoad(String assemblyString, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection) at System.Reflection.Assembly.Load(String assemblyString) at System.Web.Configuration.CompilationSection.LoadAssemblyHelper(String assemblyName, Boolean starDirective) The specific DLL that fails to load varies from incident to incident, but is always one referenced by the main assembly. We're running on ASP.NET 3.5 on Windows Server 2008. This seems to happen in batches affecting some but not all of sites on the same App Pool. We have a large number of sites all running the same code. Once a site has failed to load a DLL it throws up a Yellow Screen of Death until the next App Pool recycle. We haven't been able to reproduce this behavior and the sites seem to work fine for days or weeks at a time (and many App Pool recycles) before failing. Has anybody else seen similar behavior? Update: We've tried reproducing the failure by setting up a few hundred sites and writing a script to hit them repeatedly while recycling the App Pool once every couple of minutes and were unable to accomplish much other than loading down the server's CPU for a few days straight. We then tried messing (locking one of the DLLs, changing the file permissions) with the copies of the DLLs that ASP.NET makes and managed to reproduce similar behavior but not the same exception. Does anybody have any ideas on how to adjust the security policy to get it to throw a System.Security.Policy.PolicyException: Execution permission cannot be acquired. when loading a specific DLL?

• WinForms AcceptButton not working?

  - by Svish

  Ok, this is bugging me, and I just can't figure out what is wrong... I have made two forms. First form just has a simple button on it, which opens the other as a dialog like so: using (Form2 f = new Form2()) { if (f.ShowDialog() != DialogResult.OK) MessageBox.Show("Not OK"); else MessageBox.Show("OK"); } The second, which is that Form2, has two buttons on it. All I have done is to set the forms AcceptButton to one, and CancelButton to the other. In my head this is all that should be needed to make this work. But when I run it, I click on the button which opens up Form2. I can now click on the one set as CancelButton, and I get the "Not OK" message box. But when I click on the one set as AcceptButton, nothing happens? The InitializeComponent code of Form2 looks like this: private void InitializeComponent() { this.button1 = new System.Windows.Forms.Button(); this.button2 = new System.Windows.Forms.Button(); this.SuspendLayout(); // // button1 // this.button1.Location = new System.Drawing.Point(211, 13); this.button1.Name = "button1"; this.button1.Size = new System.Drawing.Size(75, 23); this.button1.TabIndex = 0; this.button1.Text = "button1"; this.button1.UseVisualStyleBackColor = true; // // button2 // this.button2.DialogResult = System.Windows.Forms.DialogResult.Cancel; this.button2.Location = new System.Drawing.Point(130, 13); this.button2.Name = "button2"; this.button2.Size = new System.Drawing.Size(75, 23); this.button2.TabIndex = 1; this.button2.Text = "button2"; this.button2.UseVisualStyleBackColor = true; // // Form2 // this.AcceptButton = this.button1; this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.CancelButton = this.button2; this.ClientSize = new System.Drawing.Size(298, 59); this.Controls.Add(this.button2); this.Controls.Add(this.button1); this.Name = "Form2"; this.Text = "Form2"; this.Load += new System.EventHandler(this.Form2_Load); this.ResumeLayout(false); } I have done nothing else than add those two buttons, and set the AcceptButton and CancelButton. Why doesn't it work?

• Remove namespace declarations from web service response

  - by Fernando

  I have a web service that returns a simple object: [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.4927")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.SoapTypeAttribute(Namespace="urn:CHAMADO")] public partial class STRUCCHAMADOOUT : object, System.ComponentModel.INotifyPropertyChanged { private string cODField; private string mSGField; /// <remarks/> public string COD { get { return this.cODField; } set { this.cODField = value; this.RaisePropertyChanged("COD"); } } /// <remarks/> public string MSG { get { return this.mSGField; } set { this.mSGField = value; this.RaisePropertyChanged("MSG"); } } public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged; protected void RaisePropertyChanged(string propertyName) { System.ComponentModel.PropertyChangedEventHandler propertyChanged = this.PropertyChanged; if ((propertyChanged != null)) { propertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName)); } } } this class was generated by wsdl.exe, based on a wsdl file provided by the client. This is the web method: [WebMethod(MessageName="CHAMADORequest")] [SoapRpcMethod( Action = "urn:CHAMADO#CHAMADO", RequestNamespace = "urn:CHAMADO", RequestElementName = "CHAMADO", ResponseNamespace = "", ResponseElementName = "return", Use = SoapBindingUse.Literal )] [return: XmlElement("return")] public STRUCCHAMADOOUT CHAMADO(STRUCCHAMADOIN ENTRADA) { STRUCCHAMADOOUT result = new STRUCCHAMADOOUT(); try { string str = Util.GetRequestXML(); persist(getResult<Entidades.Chamado>(str, "ENTRADA", string.Empty)); result.COD = "1"; result.MSG = "Operação realizada com sucesso"; } catch (Exception ex) { result.COD = "0"; result.MSG = ex.Message + Environment.NewLine + ex.StackTrace; } return result; } The client is saying that his system is raising an error because the service response has namespaces declaration, just like this: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <CHAMADOResponse xmlns="urn:CHAMADO" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <return xmlns=""> <COD xmlns="urn:CHAMADO">1</COD> <MSG xmlns="urn:CHAMADO">Operação realizada com sucesso</MSG> </return> </CHAMADOResponse> Now, I managed to remove the namespaces from COD and MSG by applying the attriute WebServiceBinding(ConformsTo = WsiProfiles.None) to the service's class and setting ResponseNamespace to an empty string. But CHAMADOResponse still have the namespaces declaration. I'm pretty sure that it should not be done like that. In fact, I don't believe that the namespaces are the problem at all. This project has been hard since the begining, as we had to create services that matched legacy wsdl. My question is: is there a way that I could remove all that namespaces declaration from the web service response?

• An existing connection was forcibly closed by the remote host

  I have a fat VB.NET Winform client that is using the an old asmx style web service. Very often, when I perform query that takes a while, I get the subject error. The error happenes The error seems to occur in < 1 min, which is far less that the web service timeout value that I have set or the timeout value on the ADO Command object that is performing the query within the web server. It seems to occur whenever I am performing a large query that expects to return a lot of rows or when I am sending up a large amount of data to the web service. For example, it just occurred when I was passing a large dataset to the web server: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at Smit.Pipeline.Bo.localhost.WsSR.SaveOptions(String emailId, DataSet dsNeighborhood, DataSet dsOption, DataSet dsTaskApplications, DataSet dsCcUsers, DataSet dsDistinctUsers, DataSet dsReferencedApplications) in C:\My\Code\Pipeline2\Smit.Pipeline.Bo\Web References\localhost\Reference.vb:line 944 at Smit.Pipeline.Bo.Options.Save(TaskApplications updatedTaskApplications) in I've been looking a tons of postings on this error and it is surprising at how varied the circumstances which cause this error are. I've tried messing with Wireshark, but I am clueless how to use it. This application only has about 20 users at any one time and I am able to reproduce this error in the middle of the night when probably no one is using the app, so I don't think that the number of requests to the web server or to the database is high. It's probably one right now when I just got the error now. It seems to have to do everything with the amt of data being passed in either direction. This error is really chronic and killing me. Please help.

(1) I need to press command buttons twice to Edit/Update. (2) Changes in the cell values are not updated in the database. I.e. edited cell values are not committing. Can anyone give me a solution?

• WP7 silverlight custom control using popup

  - by Miloud B.

  Hi guys, I'm creating a custom datepicker, I have a textbox, once clicked it opens a calendar within a popup. What I want to do is change the size of the popup so it shows my whole calendar, but I can't manage to change it..., I've tried using Height, Width, MinHeight, MinWidth... but it doesn't work, the popup keep showing with a fixed size. The thing is that my popup's parent property isn't evaluated since it has expression issues (according to debugger), so I'm sure my popup's parent isn't the main screen( say layout grid). How can I for example make my popup open within a specific context ? This part of my code isn't XAML, it's C# code only and it looks like: using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using System.Windows.Controls.Primitives; namespace CalendarBranch.components { public class wpDatePicker:TextBox { private CalendarPopup calendar; private Popup popup; public wpDatePicker() { this.calendar = new CalendarPopup(); this.popup = new Popup(); this.popup.Child = this.calendar; this.popup.Margin = new Thickness(0); this.MouseLeftButtonUp += new MouseButtonEventHandler(wpDatePicker_MouseLeftButtonUp); this.calendar.onDateSelect += new EventHandler(onDateSelected); this.IsReadOnly = true; } protected void wpDatePicker_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { this.popup.Height = this.calendar.Height; this.popup.Width = this.calendar.Width; this.popup.HorizontalAlignment = HorizontalAlignment.Center; this.popup.VerticalAlignment = VerticalAlignment.Center; this.popup.HorizontalOffset = 0; this.popup.VerticalOffset = 0; this.popup.MinHeight = this.calendar.Height; this.popup.MinWidth = this.calendar.Width; this.popup.IsOpen = true; } private void onDateSelected(Object sender, EventArgs ea) { this.Text = this.calendar.SelectedValue.ToShortDateString(); this.popup.IsOpen = false; } } } PS: the class Calendar is simply a UserControl that contains a grid with multiple columns, HyperLinkButtons and TextBlocks, so nothing special. Thank you in advance guys ;) Cheers Miloud B.

• A SelfHosted WCF Service over Basic HTTP Binding doesn't support more than 1000 concurrent requests

  - by Krishnan

  I have self hosted a WCF Service over BasicHttpBinding consumed by an ASMX Client. I'm simulating a concurrent user load of 1200 users. The service method takes a string parameter and returns a string. The data exchanged is less than 10KB. The processing time for a request is fixed at 2 seconds by having a Thread.Sleep(2000) statement. Nothing additional. I have removed all the DB Hits / business logic. The same piece of code runs fine for 1000 concurrent users. I get the following error when I bump up the number to 1200 users. System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at WCF.Throttling.Client.Service.Function2(String param) This exception is often reported on DataContract mismatch and large data exchange. But never when doing a load test. I have browsed enough and have tried most of the options which include, Enabled Trace & Message log on server side. But no errors logged. To overcome Port Exhaustion MaxUserPort is set to 65535, and TcpTimedWaitDelay 30 secs. MaxConcurrent Calls is set to 600, and MaxConcurrentInstances is set to 1200. The Open, Close, Send and Receive Timeouts are set to 10 Minutes. The HTTPWebRequest KeepAlive set to false. I have not been able to nail down the issue for the past two days. Any help would be appreciated. Thank you.

• Web reference problem on WCF

  - by kaivalya

  I have a WCF service which I am able to connect to from my web application and get data. I now added a web reference to this wcf project to a wsdl file that a shipping company provides. Intention is to get shipping quotes.. I am able to access the objects that are generated from this wsdl file but when I call service.Authenticate("DEMO"); method almost nothing happens. I debug and see the debugger continue to the next lines but there is no change on service parameters and service.isauthorized is null.. Can you lead me to how I should debug this further and things I should check, or if there are additional steps that I need to ensure to have a web reference working on wcf app Thanks using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; using ShippingCalculator.com.freight.api; namespace ShippingCalculator { public class ShippingService : IShippingService { freight_service service = new freight_service(); public string GetData(int value) { service.setConnectionType(".net"); service.Authenticate("DEMO"); OriginRequest origin = new OriginRequest(); origin.zip = "60101"; DestinationRequest destination = new DestinationRequest(); destination.zip = "10001"; PackageRequest package = new PackageRequest(); package.weight = "10"; ShipmentInfoRequest shipmentInfo = new ShipmentInfoRequest(); shipmentInfo.ship_date = DateTime.Now.AddDays(5); service.setOrigin(origin); service.setDestination(destination); service.setPackage(package); service.setShipmentInfo(shipmentInfo); Quote quote = service.getQuote(); return string.Format("Quote Number: {0}<br /> ", quote.QuoteNumber); } } } using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using ShippingTestApp.ShippingServiceReference; namespace ShippingTestApp.Controllers { [HandleError] public class HomeController : Controller { public ActionResult Index() { ShippingServiceClient shipClient = new ShippingServiceClient(); shipClient.GetData(0); ViewData["Message"] = shipClient.GetData(0); return View(); } } }

• Best way to run remote VBScript in ASP.net? WMI or PsExec?

  - by envinyater

  I am doing some research to find out the best and most efficient method for this. I will need to execute remote scripts on a number of Window Servers/Computers (while we are building them). I have a web application that is going to automate this task, I currently have my prototype working to use PsExec to execute remote scripts. This requires PsExec to be installed on the system. A colleague suggested I should use WMI for this. I did some research in WMI and I couldn't find what I'm looking for. I want to either upload the script to the server and execute it and read the results, or already have the script on the server and execute it and read the results. I would prefer the first option though! Which is more ideal, PsExec or WMI? For reference, this is my prototype PsExec code. This script is only executing a small script to get the Windows OS and Service Pack Info. Protected Sub windowsScript(ByVal COMPUTERNAME As String) ' Create an array to store VBScript results Dim winVariables(2) As String nameLabel.Text = Name.Text ' Use PsExec to execute remote scripts Dim Proc As New System.Diagnostics.Process ' Run PsExec locally Proc.StartInfo = New ProcessStartInfo("C:\Windows\psexec.exe") ' Pass in following arguments to PsExec Proc.StartInfo.Arguments = COMPUTERNAME & " -s cmd /C c:\systemInfo.vbs" Proc.StartInfo.RedirectStandardInput = True Proc.StartInfo.RedirectStandardOutput = True Proc.StartInfo.UseShellExecute = False Proc.Start() ' Pause for script to run System.Threading.Thread.Sleep(1500) Proc.Close() System.Threading.Thread.Sleep(2500) 'Allows the system a chance to finish with the process.

• What makes a Winform position initially stale?

  - by msorens

  The code below demonstrates a very simple problem; I am hoping that I am just missing a setting that someone might be able to reveal. Goal (1) Launch main winform (MainForm). (2) Press button to display secondary winform (ShadowForm) that is semi-transparent and should exactly overlay MainForm. What Actually Happens Scenario 1: Launch main winform then press button: ShadowForm displays with correct size but incorrect location, lower and to the right (as if it was cascaded). Press button to close ShadowForm again. Press button once more to reopen ShadowForm and now it is in the correct position, covering MainForm. Scenario 2: Launch main winform, move it around, then press button: ShadowForm displays with correct size but incorrect location (where the MainForm was before moving it). Press button to close; press again to reopen and now ShadowForm is in the correct position. using System; using System.Windows.Forms; namespace LocationTest { static class Program { static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new MainForm()); } } public class MainForm : Form { ShadowForm shadowForm = new ShadowForm(); Button button1 = new Button(); System.ComponentModel.IContainer components = null; public MainForm() { this.SuspendLayout(); this.button1.Location = new System.Drawing.Point(102, 44); this.button1.Size = new System.Drawing.Size(75, 23); this.button1.Text = "button1"; this.button1.Click += new System.EventHandler(this.button1_Click); this.ClientSize = new System.Drawing.Size(292, 266); this.Controls.Add(this.button1); this.ResumeLayout(false); } private void button1_Click(object sender, EventArgs e) { if (shadowForm.Visible) { shadowForm.Hide(); } else { shadowForm.Size = Size; // this always works shadowForm.Location = Location; // this fails first time, but works second time! shadowForm.Show(); } } protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } } public class ShadowForm : Form { private System.ComponentModel.IContainer components = null; public ShadowForm() { this.SuspendLayout(); this.BackColor = System.Drawing.Color.Black; this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; this.Opacity = 0.5; this.Click += new System.EventHandler(this.ShadowForm_Click); this.ResumeLayout(false); } private void ShadowForm_Click(object sender, EventArgs e) { Hide(); } protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } } }

Update 1: This is some log details from Event viewer that I thought that they may be useful for this problem: FCB::Open failed: Could not open file e:\sql11_main_t.obj.x86release\sql\mkmastr\databases\objfre\i386\MSDBData.mdf for file number 1. OS error: 3(The system cannot find the path specified.). The resource database build version is 11.00.3000. This is an informational message only. No user action is required.

Diagnose and correct the operating system error, and retry the operation. Starting up database 'model'.

• VMRC equivalent for Hyper-V?

  - by Ian Boyd

  VMRC was the client tool used to connect to virtual machines running on Virtual Server. Upgrading to Windows Server 2008 R2 with the Hyper-V role, i need a way for people to be able to use the virtual machines. Note: not all virtual machines will have network connectivity not all virtual machines will be running Windows some people needing to connect to a virtual machine will be running Windows XP Hyper-V manager, allowing management of the hyper-v server, is less desirable (since it allows management of the hyper-v server (and doesn't work on all operating systems)) What is the Windows Server 2008 R2 equivalent of VMRC; to "vnc" to a virtual server? Update: i think Tatas was suggesting Microsoft System Center Virtual Machine Manager Self-Service Portal 2.0 (?): Which requires SQL Server IIS Installing those would unfortunately violate our Windows Server 2008 R2 license. i might be looking at the wrong product link, since commenter said there is a version that doesn't require "System Center". Update 2: The Windows Server 2008 R2 running HyperV is being licensed with the understanding that it only be used to host HyperV. From the [Windows Server 2008 R2 Licensing FAQ][4]: Q. If I have one license for Windows Server 2008 R2 Standard and want to run it in a virtual operating system environment, can I continue running it in the physical operating system environment? A. Yes, with Windows Server 2008 R2 Standard, you may run one instance in the physical operating system environment and one instance in the virtual operating system environment; however, the instance running in the physical operating system environment may be used only to run hardware virtualization software, provide hardware virtualization services, or to run software to manage and service operating system environments on the licensed server. This is why i'm weary about installing IIS or SQL Server.

• Scripting an automated SQLServer 2008 DR move

  - by ItsAMystery

  Hi All We use the built in logshipping in SQLServer to logship to our DR site but once in a month do a DR test which requires us to move back and forth between our Live and BAckup servers. We run multiple (30) databases on the system so manually backing up the final logs and disabling the jobs is too much work and takes too long. I though no problem, I will script it but have run into trouble with it always complaninig that the final logship is too early to apply even though I dont export the final log until putting the database into norecovery mode. Firstly, does any one no a simple and reliable way of doing this? I have lokoed at some 3rd party software (redgate sqlbackup I think it was) but that didnt make it easy in this situation either. What I want to be able to do is basically run a script (a series of stored procedures) to get me to DR and run another to get me back with no dataloss. My scripts are very simplistic at the moment but here they are: 2 servers Primary Paris Secondary ParisT The StartAgentJobAndWait is a script written by someone else (ta) and just checks the jobs have finished or quits it if it never ends. At the moment I am just using a test database called BOB2 but if I can get it working will pass in the database and job names. from PARIS: /* Disable backup job */ exec msdb..sp_update_job @job_name = 'LSBackup_BOB2', @enabled = 0 exec PARIST.msdb..sp_update_job @job_name = 'LSCopy_PARIS_BOB2', @enabled = 0 exec PARIST.msdb..sp_update_job @job_name = 'LSRestore_PARIS_BOB2', @enabled = 0 exec PARIST.master.dbo.DRStage2 ParisT DRStage2 DECLARE @RetValue varchar (10) EXEC @RetValue = StartAgentJobAndWait LSCopy_PARIS_BOB2 , 2 SELECT ReturnValue=@RetValue if @RetValue = 1 begin print 'The Copy Task completed Succesffuly' END ELSE print 'The Copy task failed, This may or may not be a problem, check restore state of database' SELECT @RetValue = 0 EXEC @RetValue = StartAgentJobAndWait LSRestore_PARIS_BOB2 , 2 SELECT ReturnValue=@RetValue if @RetValue = 1 begin print 'The Restore Task completed Succesffuly' END ELSE print 'The Copy task failed, This may or may not be a problem, check restore state of database' exec PARIS.master.dbo.DRStage3 /* Do the last logship and move it to Trumpington */ BACKUP log "BOB2" to disk='c:\drlogshipping\BOB2.bak' with compression, norecovery EXEC xp_cmdshell 'copy c:\drlogshipping \\192.168.7.11\drlogshipping' EXEC PARIST.master.dbo.DRTransferFinish AS BEGIN restore database "BOB2" from disk='c:\drlogshipping\bob2.bak' with recovery
