• Converting from CVS to SVN to Hg, does 'hg convert' require pointing to an SVN checkout or just a re

  - by Terry

  As part of migrating full CVS history to Hg, I've used cvs2svn to create an SVN repo in a local directory. It's first level directory structure is: 2010-04-21 09:39 AM <DIR> . 2010-04-21 09:39 AM <DIR> .. 2010-04-21 09:39 AM <DIR> locks 2010-04-21 09:39 AM <DIR> hooks 2010-04-21 09:39 AM <DIR> conf 2010-04-21 09:39 AM 229 README.txt 2010-04-21 11:45 AM <DIR> db 2010-04-21 09:39 AM 2 format 2 File(s) 231 bytes After setting up hg and the convert extension and attempting the convert, I get the following on convert: C:\>hg convert file://localhost/Users/terry/Desktop/repoSVN assuming destination repoSVN-hg initializing destination repoSVN-hg repository file://localhost/Users/terry/Desktop/repoSVN does not look like a CVS checkout file://localhost/Users/terry/Desktop/repoSVN does not look like a Git repo file://localhost/Users/terry/Desktop/repoSVN does not look like a Subversion repo file://localhost/Users/terry/Desktop/repoSVN is not a local Mercurial repo file://localhost/Users/terry/Desktop/repoSVN does not look like a darcs repo file://localhost/Users/terry/Desktop/repoSVN does not look like a monotone repo file://localhost/Users/terry/Desktop/repoSVN does not look like a GNU Arch repo file://localhost/Users/terry/Desktop/repoSVN does not look like a Bazaar repo file://localhost/Users/terry/Desktop/repoSVN does not look like a P4 repo abort: file://localhost/Users/terry/Desktop/repoSVN: missing or unsupported repository I have TortoiseHg installed.

Do I need to do a checkout and point hg convert to it for this to work properly?

• SimpleJdbcCall ignoring JdbcTemplate fetch size

  - by user289429

  We are calling the pl/sql stored procedure through Spring SimpleJdbcCall, the fetchsize set on the JdbcTemplate is being ignored by SimpleJdbcCall. The rowmapper resultset fetch size is set to 10 even though we have set the jdbctemplate fetchsize to 200. Any idea why this happens and how to fix it? Have printed the fetchsize of resultset in the rowmapper in the below code snippet - Once it is 200 and other time it is 10 even though I use the same JdbcTemplate on both occassion. This direct execution through jdbctemplate returns fetchsize of 200 in the row mapper jdbcTemplate = new JdbcTemplate(ds); jdbcTemplate.setResultsMapCaseInsensitive(true); jdbcTemplate.setFetchSize(200); List temp = jdbcTemplate.query("select 1 from dual", new ParameterizedRowMapper() { public Object mapRow(ResultSet resultSet, int i) throws SQLException { System.out.println("Direct template : " + resultSet.getFetchSize()); return new String(resultSet.getString(1)); } }); This execution through SimpleJdbcCall is always returning fetchsize of 10 in the rowmapper jdbcCall = new SimpleJdbcCall(jdbcTemplate).withSchemaName(schemaName) .withCatalogName(catalogName).withProcedureName(functionName); jdbcCall.returningResultSet((String) outItValues.next(), new ParameterizedRowMapper<Map<String, Object>>() { public Map<String, Object> mapRow(ResultSet rs, int row) throws SQLException { System.out.println("Through simplejdbccall " + rs.getFetchSize()); return extractRS(rs, row); } }); outputList = (List<Map<String, Object>>) jdbcCall.executeObject(List.class, inParam);

• Maven: compile aspectj project containing Java 1.6 source

  - by gmale

  What I want to do is fairly easy. Or so you would think. However, nothing is working properly. Requirement: Using maven, compile Java 1.6 project using AspectJ compiler. Note: Our code cannot compile with javac. That is, it fails compilation if aspects are not woven in (because we have aspects that soften exceptions). Questions (based on failed attempts below): Either 1) How do you get maven to run the aspectj:compile goal directly, without ever running compile:compile? 2) How do you specify a custom compilerId that points to your own ajc compiler? Thanks for any and all suggestions. These are the things I've tried that have let to my problem/questions: Attempt 1 (fail): Specify aspectJ as the compiler for the maven-compiler-plugin: org.apache.maven.plugins maven-compiler-plugin 2.2 1.6 1.6 aspectj org.codehaus.plexus plexus-compiler-aspectj 1.8 This fails with the error: org.codehaus.plexus.compiler.CompilerException: The source version was not recognized: 1.6 No matter what version of the plexus compiler I use (1.8, 1.6, 1.3, etc), this doesn't work. I actually read through the source code and found that this compiler does not like source code above Java 1.5. Attempt 2 (fail): Use the aspectJ-maven-plugin attached to the compile and test-compile goals: org.codehaus.mojo aspectj-maven-plugin 1.3 1.6 1.6 compile test-compile This fails when running either: mvn clean test-compile mvn clean compile because it attempts to execute compile:compile before running aspectj:compile. As noted above, our code doesn't compile with javac--the aspects are required. So mvn would need to skip the compile:compile goal altogether and run only aspectj:compile. Attempt 3 (works but unnacceptable): Use the same configuration above but instead run: mvn clean aspectj:compile This works, in that it builds successfully but it's unacceptable in that we need to be able to run the compile goal and the test-compile goal directly (m2eclipse auto-build depends on those goals). Moreover, running it this way would require that we spell out every goal we want along the way (for instance, we need resources distributed and tests to be run and test resources deployed, etc)

• Problem with Tapestry palette's arrow icons in IE8

  - by JellyHead

  I'm using Tapestry to create pages for a web app, and have been using the palette component to add/delete items to/from a group. The page looks great in Firefox (Tapestry seems biased towards Firefox), but my customers will all be using Internet Explorer (any versions from 6, 7, & 8) and in IE8, the disabled arrow buttons look awful. In Firefox, they are faded, using an opacity setting of 25%, but this doesn't work in IE8 and instead you get a faded image with an ugly black border around the image. In tapestry-core's stylesheet (default.css), you have the following for a disabled arrow button. DIV.t-palette-controls BUTTON[disabled] IMG { filter: alpha(opacity = 25); -moz-opacity: .25; } These are clearly out of date, as -moz-opacity is no longer supported by Firefox (use opacity: 25 instead). The problem is with filter: "alpha(opacity = 25);". If I remove this, the arrows look fine in IE8, but they are not faded. I got the magic instruction: -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(opacity=25)"; from various websites, but putting this in does not work either - the arrow icons are ugly again. The icon itself (distributed with Tapestry) just seems to be a regular PNG, but I'm not an expert on image formats, so maybe there's a problem there? Anyone else had this problem?

• ASP.NET Timer Event

  - by K Ratnajyothi

  protected void SubmitButtonClicked(object sender, EventArgs e) { System.Timers.Timer timer = new System.Timers.Timer(); --- --- //line 1 get_datasource(); String message = "submitted."; ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "popupAlert", "popupAlert(' " + message + " ');", true); timer.Interval = 30000; timer.Elapsed += new ElapsedEventHandler(timer_tick); // Only raise the event the first time Interval elapses. timer.AutoReset = false; timer.Enabled = true; } } protected void timer_tick(object sender, EventArgs e) { //line 2 get_datasource(); GridView2.DataBind(); } The problem is with the data in the grid view that is being displayed... since when get_datasource which is after line 1 is called the updated data is displayed in the grid view since it is a postback event but when the timer event handler is calling the timer_tick event the get_datasource function is called but after that the updated data is not visible in the grid view. It is nnot getting updated since the timer_tick is not a post back event

• [Architecture] Roles for white-label service access.

  - by saurabhj

  Okay, I know I'm doing something wrong - but can't figure out a better way. I am developing a website which is going to allow users to setup their own mini-websites. Something like Ning. Also, I have only 1 basic login and access to each mini website is provided (right now) via roles. So the way I am doing this right now is: Everytime a new mini website is created - say blah, I create 2 roles in my application. blah_users and blah_admin The user creating the mini website is given the role - blah_admin and every other user wanting to join this mini website (or network) is given the role - blah_user. Anyone can view data from any website. However to add data, one must be a member of that mini site (must have the blah_user role assigned) The problem that I am facing is that by doing a role based system, I'm having to do loads of stuff manually. Asp.Net 2 controls which work on the User.IsAunthenticated property are basically useless to me now because along with the IsAuthenticated property, I must also check if the user has the proper role. I'm guessing there is a better way to architect the system but I am not sure how. Any ideas? This website is being developed in ASP.Net 2 on IIS 6. Thanks a tonne!

• How to compile a schema that uses a DataSet (xs:schema)?

  - by Yaron Naveh

  I have created the simplest web service in c#: public void AddData(DataSet ds) The generated schema (Wsdl) looks like this: <s:schema xmlns:s="http://www.w3.org/2001/XMLSchema"> ... <s:element ref="s:schema" /> ... </s:schema> Note the schema does not contain any import/include elements. I am trying to load this schema to a c# System.Xml.XmlSchema and add it to System.Xml.XmlSchemaSet: var set = new XmlSchemaSet(); var fs = new FileStream(@"c:\temp\schema.xsd", FileMode.Open); var s = XmlSchema.Read(fs, null); set.Add(s); set.Compile(); The last line throws this exception: The 'http://www.w3.org/2001/XMLSchema:schema' element is not declared. It kind of makes sense: The schema generated by .Net uses the "s:schema" type which is declared in a schema which is not imported. Why does .Net create a non valid schema? How to compile the schema anyway? Whay I did is download the schema in http://www.w3.org/2001/XMLSchema and added it to the XmlSchemaSet also. This did not work since that online schema contains DTD definition. I had to manually remove it and now all works. Does this make sense or am I missing something?

• How to I get the value of a custom soap header in WCF

  - by Jason Coyne

  I have created a custom soap header, and added it into my message via IClientMessageInspector public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel) { var header = new MessageHeader<AuthHeader>(); header.Content = new AuthHeader(Key); header.Actor = "Anyone"; var header2 = header.GetUntypedHeader("Auth", "xWow"); request.Headers.Add(header2); return null; } [DataContract(Name="Auth")] public class AuthHeader { public AuthHeader(string key) { this.Key = key; } [DataMember] public string Key { get; set; } } I also have an IDispatchMessageInspector, and I can find the correct header in the list. However, there is no value. I know that the value went across the wire correctly, because the message string is correct <s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">\r\n <s:Header>\r\n <Auth s:actor=\"Anyone\" xmlns=\"xWow\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">\r\n <Key xmlns=\"http://schemas.datacontract.org/2004/07/xWow.Lib\">HERE IS MY KEY VALUE!!!!</Key>\r\n </Auth>\r\n <To s:mustUnderstand=\"1\" xmlns=\"http://schemas.microsoft.com/ws/2005/05/addressing/none\">http://localhost:26443/AuthService.svc</To>\r\n <Action s:mustUnderstand=\"1\" xmlns=\"http://schemas.microsoft.com/ws/2005/05/addressing/none\">http://tempuri.org/IAuthService/GetPayload</Action>\r\n </s:Header>\r\n <s:Body>\r\n <GetPayload xmlns=\"http://tempuri.org/\" />\r\n </s:Body>\r\n</s:Envelope>" But there does not seem to be any property to retrieve this value. The MessageHeaderInfo class has Actor, etc, but nothing else useful I can find. On the client side I had to convert between Header and Untyped header, is there an equivalent operation on the server?

• How to open a help webpage after installation is complete

  - by Kapil

  I have built an installer for my windows app using the VisualStudio 2008 IDE. I also use some custom-actions to do a few extra stuff at the time of installation/uninstallation. What I also want to do is that when the installation is completed, the installer should launch a help webpage or a getting-started page for the users to know how to go ahead with the app. I am doing the following for this: private void CustomInstaller_Committed(object sender, InstallEventArgs e) { System.Windows.Forms.LinkLabel lbl = new System.Windows.Forms.LinkLabel(); lbl.Links.Remove(lbl.Links[0]); lbl.Links.Add(0, lbl.Text.Length, "http://www.mywebsite.com/help.aspx"); ProcessStartInfo pInfo = new ProcessStartInfo(lbl.Links[0].LinkData.ToString()); Process.Start(pInfo); } Also, I set the event handler as such: this.Committed += new InstallEventHandler(CustomInstaller_Committed); This is launching the webpage, but not at the right point in the flow where I would have wanted it. It launches the IE browser even before the user dismisses the installation window (i.e clicks 'Close' in the Installation Completed dialog box). I want the webpage to open only when the user finally dismisses the installation. Any ideas how can I achieve this? Thanks, Kapil

• How to serialize List<object>

  - by afin

  I am writing common functions to serialize the given object and List<object> as follows public string SerializeObject(Object pObject)// for given object { try { String XmlizedString = null; MemoryStream memoryStream = new MemoryStream(); XmlSerializer xs = new XmlSerializer(typeof(pObject)); XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8); xs.Serialize(xmlTextWriter, pObject); memoryStream = (MemoryStream)xmlTextWriter.BaseStream; XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray()); return XmlizedString; } catch (Exception e) { System.Console.WriteLine(e); return null; } } public string SerializeObject(List<Object> pObject)// for given List<object> { try { String XmlizedString = null; MemoryStream memoryStream = new MemoryStream(); XmlSerializer xs = new XmlSerializer(typeof(pObject)); XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8); xs.Serialize(xmlTextWriter, pObject); memoryStream = (MemoryStream)xmlTextWriter.BaseStream; XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray()); return XmlizedString; } catch (Exception e) { System.Console.WriteLine(e); return null; } } first one is working fine. If I pass any type, it is successfully returning xml string. But second one is throwing error. what could be wrong?

• Why does Http Web Request and IWebProxy work at wierd times

  - by Mike Webb

  Another question about Web proxy. Here is my code: IWebProxy Proxya = System.Net.WebRequest.GetSystemWebProxy(); Proxya.Credentials = CredentialCache.DefaultNetworkCredentials; HttpWebRequest rqst = (HttpWebRequest)WebRequest.Create(targetServer); rqst.Proxy = Proxya; rqst.Timeout = 5000; try { rqst.GetResponse(); } catch(WebException wex) { connectErrMsg = wex.Message; proxyworks = false; } This code fails the first time it is called. After that on successive calls it works sometimes, but not others. It also never hits the catch block. Now the weird part. If I add a MessageBox.Show(msg) call in the first section of code before the GetResponse() call this all will work every time. Here is an example: try { // ========Here is where I make the call and get the response======== System.Windows.Forms.MessageBox.Show("Getting Response"); // ========This makes the whole thing work every time======== rqst.GetResponse(); } catch(WebException wex) { connectErrMsg = wex.Message; proxyworks = false; } I'm baffled about why it is behaving this way. I don't know if the timeout is not working (it's in milliseconds, not seconds, so should timeout after 5 seconds, right?...) or what is going on. The most confusing this is that the message box call makes it all work. So any help and suggestions on what is happening is appreciated. These are the kind of bugs that drive me absolutely out of my mind.

• Webservice complex types and class inheritance

  - by pygorex1

  Using the following Webservice definition using aClientArgs as a complex type: [System.Web.Script.Services.ScriptService] public class Controller : System.Web.Services.WebService { [WebMethod] public void save_client(aClientArgs client) { // Save client data } } Then defining aClientArgs as a sub-class: public class aArgs { public string id = null; public string name = null; } public class aClientArgs : aArgs { public string address = null; public string website = null; } Returns the following WSDL fragment for the save_client args: <save_client xmlns="http://tempuri.org/"> <client> <address>string</address> <website>string</website> </client> </save_client> When I'm expecting the following: <save_client xmlns="http://tempuri.org/"> <client> <id>string</id> <name>string</name> <address>string</address> <website>string</website> </client> </save_client> So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

• Terrible DotNetNuke performance

  - by Peter Bridger

  I'm involved with a project using DotNetNuke version 05.01.04 Community Edition. We are building our new Intranet using it, but performance is terrible. We have five people adding pages and content to it and every 15-30 seconds they experience a pause of 10 seconds or longer before the system continues and the next screens loads. The server is Windows 2003, 3.8GHz with 1GB of RAM. I'm told by our server admin that the CPU and memory performance don't appear to be the bottleneck. We currently have 350 pages in the system, we a plan to add 1000. So we need to resolve this performance problem so that we can enter content and so we can go live. I just can't see where the bottleneck is. Is there a good why to determine the bottleneck when using DotNetNuke? Modules installed Publish:Engage (Not currently in use) Page Blaster (Doesn't appear to providing caching when users logged in using Integrated Authentication) SimpleGallery XMod Content Manager IIS Setup Application recycling completely disabled (Apart from a 2am recycle) New findings: 18th March 2010 The main bottleneck was due to version 5.1.4 having a bug which caused 1300 database roundtrips on an average page, due to broken database in-memory caching. We've upgraded to 5.2.4 which has resolved this bottleneck. Now the next biggest bottleneck is the navigation. We've used both DDR:Menu and DDN:Nav, but both have a major impact on performance. Is there a navigation interface out there that doesn't drain performance so badly?

• Facebook with RestFB (Java)

  - by Trick

  I just began to use this and I already stumbled on some from-my-side-strange errors. I am using RestFB jar. My problem is, that I can not get my session key (this is the start of everything :)). FacebookClient facebookClient = new DefaultFacebookClient(API_KEY, SECRET_KEY); try { String token = facebookClient.execute("auth.createToken", String.class, Parameter.with("null", "null")); System.out.println(token); String session = facebookClient.execute("auth.getSession", String.class, Parameter.with("auth_token", token)); System.out.println(session); } catch (FacebookException e) { e.printStackTrace(); } I get the token correctly. Parameter.with("null,"null") is there because it demands at least one, but method for creating token doesn't expect any. When trying to get the session key, I get the following error: com.restfb.FacebookResponseStatusException: Received Facebook error response (code 100): Invalid parameter at com.restfb.DefaultFacebookClient.throwFacebookResponseStatusExceptionIfNecessary(DefaultFacebookClient.java:357) at com.restfb.DefaultFacebookClient.makeRequest(DefaultFacebookClient.java:320) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:188) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:178) Documentation for getting session doesn't say any more parameters are required! Did anybody already try this JAR or do you have any other solution for Java? EDIT: Does the application needs to be "published" in searchers to be able to do this??

• How to determine the correct (case sensitive) URL for a SharePoint site

  - by Goyuix

  SharePoint is generally very tolerant of accepting a URL in a case-insensitive fashion, however there are a few cases where it completely breaks down. For example, when creating a site column it somehow stores and uses the URL when it was created, and when trying to edit the field definition through the Site Column Gallery (fldedit.aspx page in the LAYOUTS) you end up throwing the error below. Value does not fall within the expected range. at Microsoft.SharePoint.SPFieldCollection.GetFieldByInternalName(String strName, Boolean bThrowException) at Microsoft.SharePoint.SPFieldCollection.GetFieldByInternalName(String strName) at Microsoft.SharePoint.ApplicationPages.BasicFieldEditPage.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) How can I reliably get the correct URL for a site/web? The SPSite.Url and SPWeb.Url properties seem to return back whatever case they are instantiated with. In other words, the site collection is provisioned using the following URL: http://server/Path/Site If I create a new Site Column using the SharePoint object model and happen to use http://server/path/site when instantiating the SPSite and SPWeb objects, the site column will be made available but when trying to access it through the gallery the error above is generated. If I correct the URL in the address bar, I can still view/modify the definition for the SPField in question, but the default URL that is generated is bogus. Clear as mud? Example code: (this is a bad example because of the case sensitivity issue) // note: site should be partially caps: http://server/Path/Site using (SPSite site = new SPSite("http://server/path/site")) { using (SPWeb web = site.OpenWeb()) { web.Fields.AddFieldAsXml("..."); // correct XML really here } }

• Error reached after genereated entity framework classes by edmgen tool

  - by loviji

  Hello, First I read this question, but this knowledge did not help to solve my problems. In initial I've created edmx file by Visual Studio. Generated files with names: uqsModel.Designer.cs uqsModel.edmx This files are located on App_Code folder. And my web app work normally. In Web Config generated connectionstring automatically. <add name="uqsEntities" connectionString="metadata=res://*/App_Code.uqsModel.csdl|res://*/App_Code.uqsModel.ssdl|res://*/App_Code.uqsModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=aemloviji\sqlexpress;Initial Catalog=uqs;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" /></connectionStrings> Then I had to generate classes by the instrument edmgen tool(full generation mode). Generated new files with names: uqsModel.cs uqsModel.csdl uqsModel.msl uqsModel.ssdl uqsViews.cs it save new classed to the folder where edmx files located before, and remove existing edmx files. And when page redirrects to any web page server side code fails. And problem: Unable to load the specified metadata resource. Some idea, please.

• USB Barcode Scanner and WM_KEYDOWN

  - by Bryce Fischer

  I am trying to write a program that can will read a barcode scanner. In addition, I need it to read the input even when the application is not the window in focus (i.e., running in system tray, etc). I found this article, titled Distinguishing Barcode Scanners from the Keyboard in WinForms, that seems to solve the exact problem. It is working pretty good, it detects my device and handles the WM_INPUT message. However, it is checking to see if the RAWINPUT.keyboard.Message is WM_KEYDOWN (0x100). It never seems to receive this. The only line of code I've altered in the code provided in the article is adding a Console.Out.WriteLine to output the actual values of that message: Console.Out.WriteLine("message: {0}", raw.keyboard.Message.ToString("X")); if (raw.keyboard.Message == NativeMethods.WM_KEYDOWN) { .... Here is what it outputs: message: B message: 1000B message: 3 message: 10003 message: 8 message: 10008 message: 3 message: 10003 message: 5 message: 10005 message: 3 message: 10003 message: 8 message: 10008 message: 8 message: 10008 message: 4 message: 10004 message: 9 message: 10009 message: 9 message: 10009 message: 3 message: 10003 The value I'm expecting to receive when this completes correctly is: 257232709 Which I verified by scanning to notepad. I don't know if the Operation System is relevant here, but I figured I should mention that I'm running this in Windows 7 64 and Visual Studio 2010 and .NET Framework 3.5. Scanner is a USB Barcode Scanner, Symbol LS2208, setup as "HID KEYBOARD EMULATION"

• Use VersionControlExt.Explorer outside Visual Studio

  - by Ian

  Hi All, I'm developing a TFS tool to assist the developers in our company. This said tool needs to be able to "browse" the TFS server like in the Source Control Explorer. I believe that by using VersionControlExt.Explorer.SelectedItems, a UI will pop-up that will enable the user to browse the TFS server (please correct me if I'm wrong). However, VersionControlExt is only accessible when developing inside Visual Studio (aka Plugin). Unfortunately, I am developing a Windows Application that won;t run inside VS. So the question is, Can I use VersionControlExt outside of Visual Studio? If yes, how? Here's an attempt on using the Changset Details Dialog outside of Visual Studio string path = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); Assembly vcControls = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Controls.dll"); Assembly vcClient = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Client.dll"); Type dialogChangesetDetailsType = vcControls.GetType("Microsoft.TeamFoundation.VersionControl.Controls.DialogChangesetDetails",true); Type[] ctorTypes = new Type[3] {vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.VersionControlSever"), vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.Changeset"), typeof(System.Boolean)}; ConstructorInfo ctorInfo = dialogChangesetDetailsType.GetConstructor(ctorTypes); Object[] ctorObjects = new Object[3] {VersionControlHelper.CurrentVersionControlServer, uc.ChangeSet, true}; Object oDialog = ctorInfo.Invoke(ctorObjects); dialogChangesetDetailsType.InvokeMember("ShowDialog", BindingFlags.InvokeMethod, null, oDialog, null);

• WPF: UnauthorizedAccessException using anonymous methods.

  - by Diego Pacheco Pedemonte

  Here is the thing, I want to create a simply app that copy many files from one site, and move them to another; but using async methods and create a new thread. private void button3_Click(object sender, RoutedEventArgs e) { //progressBar1.Maximum = _FileInfoArray.Count; DispatcherTimer dt1 = new DispatcherTimer(); foreach (FileInfo Fi in _FileInfoArray) { Thread t = new Thread(new ThreadStart(delegate() { DispatcherOperation _dispOp = progressBar1.Dispatcher.BeginInvoke(DispatcherPriority.Loaded, new Action(delegate() { File.Copy(txtdestino.Text, Fi.FullName, true); //progressBar1.Value = n; //txtstatus.Content = ("Copiados " + n.ToString() + " archivos"); //Thread.Sleep(100); } )); _dispOp.Completed += new EventHandler(_dispOp_Completed); } )); t.Start(); } } UnauthorizedAccessException is throw! It says that I can't access to txtdestino content. Some clues? -------------------------------------------------------------------------------Edited This is the version with all the changes, get the same error :( any clues? private void button4_Click(object sender, RoutedEventArgs e) { //First: Build mynames List<string> mynames = new List<string>(); foreach (FileInfo fi in _FileInfoArray) { mynames.Add(fi.FullName); } Thread t = new Thread(new ThreadStart(delegate() { foreach (string fullname in mynames) { DispatcherOperation _dispOp = progressBar1.Dispatcher.BeginInvoke(DispatcherPriority.Loaded, new Action(delegate() { string destino = System.IO.Path.Combine(@"C:\", System.IO.Path.GetFileName(fullname)); File.Copy(fullname, destino, true); //Some progressbar changes } )); _dispOp.Completed += new EventHandler(_dispOp_Completed); } } )); t.Start(); } File.Copy(txtdestino.Text, Fi.FullName, true); // here the exception is throw

• Binding a member signal to a function

  - by the_drow

  This line of code compiles correctly without a problem: boost::bind(boost::ref(connected_), boost::dynamic_pointer_cast<session<version> >(shared_from_this()), boost::asio::placeholders::error); However when assigning it to a boost::function or as a callback like this: socket_->async_connect(connection_->remote_endpoint(), boost::bind(boost::ref(connected_), boost::dynamic_pointer_cast<session<version> >(shared_from_this()), boost::asio::placeholders::error)); I'm getting a whole bunch of incomprehensible errors (linked since it's too long to fit here). On the other hand I have succeeded binding a free signal to a boost::function like this: void print(const boost::system::error_code& error) { cout << "session connected"; } int main() { boost::signal<void(const boost::system::error_code &)> connected_; connected_.connect(boost::bind(&print, boost::asio::placeholders::error)); client<>::connection_t::socket_ptr socket_(new client<>::connection_t::socket_t(conn->service())); // shared_ptr of a tcp socket socket_->async_connect(conn->remote_endpoint(), boost::bind(boost::ref(connected_), boost::asio::placeholders::error)); conn->service().run(); // io_service.run() return 0; } This works and prints session connected correctly. What am I doing wrong here?

• How to access attributes using Nokogiri

  - by Liz

  I have a simple task of accessing the values of some attributes. Below is a simple script that uses Nokogiri::XML::Builder to create a simple xml doc. require 'nokogiri' builder = Nokogiri::XML::Builder.new(:encoding => 'UTF-8') do |xml| xml.Placement(:messageId => "392847-039820-938777", :system => "MOD", :version => "2.0") { xml.objects { xml.object(:myattribute => "99", :anotherattrib => "333") xml.nextobject_ '9387toot' xml.Entertainment "Last Man Standing" } } end puts builder.to_xml puts builder.root.attributes["messageId"] The results are below: <?xml version="1.0" encoding="UTF-8"?> <Placement messageId="392847-039820-938777" version="2.0" system="MOD"> <objects> <object anotherattrib="333" myattribute="99"/> <nextobject>9387toot</nextobject> <Entertainment>Last Man Standing</Entertainment> </objects> </Placement> C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/document.rb:178:in `add_child': Document already has a root node (RuntimeError) from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/node.rb:455:in `parent=' from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/builder.rb:358:in `insert' from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/builder.rb:350:in `method_missing' from C:/Documents and Settings/etrojan/workspace/Lads/tryXPATH2.rb:15 The xml that is generated looks fine. However, my attempts to access attributes cause an error to be generated, "Document already has a root node". I don't understand why a puts statement would cause this error. Any suggestions would be greatly appreciated.

• nHibernate strategies in a web farm

  - by Pete Nelson

  Our current project at work is a new MVC web site that will use a WCF service primarily to access a 3rd party billing system via a web service as well as a small SQL database for user personalization. The WCF service uses nHibernate for the SQL database. We'd like to implement some sort of web farm for load balancing as well as failover and maintenance. I'm trying to decide the best way to handle nHibernate's caching and database concurrency if there are multiple WCF services running. Some scenarios I've been thinking about... 1) Multiple IIS servers, one WCF server. With this setup, the WCF server would be a single point of failure, but there would be no issues with nHibernate caching or database concurrency. 2) Multiple IIS servers, each with it's own WCF service. This removes a single point of failure, but now nHibernate on one machine would not know about database changes done by another machine. Some solutions to number 2 would be to use an IStatelessSession so we're not doing any caching and nHibernate is always fetching directly from the database. This might be the most feasible as our personalization database has very few objects in it. I'm also considering a 2nd-level cache such as memcached or Velocity, but it may be overkill for this system. I'm putting this out there to see if anyone has experience doing this sort of architecture and to get some ideas for a solution. Thanks!
