  • Network speeds being report as 4x higher than actual in Windows 7 SP1

    - by Synetech
    Ever since installing Windows 7 SP1, I have noticed that all programs that display my network transfer rate have been exactly 4x higher than they actually are. For example, when I download something from a high-bandwidth web site or through torrents with lots of sources, the download rate indicated is is ~5MBps (~40Mbps) even though my Internet connection has a maximum of only 1.5MBps (12Mbps). It is the same situation with the upstream bandwidth: the connection maximum is 64KBps, but I’m seeing up to 256KBps. I have tried several different programs for monitoring bandwidth throughput and they all give the same results. I also tried different times and different days, and they always show the rate as being four times too high. My initial thought was that my ISP had increased the speeds (without my noticing), which they have done before. However, I checked my ISP’s site and they have not increased the speeds. Moreover, when I look at the speeds in the program actually doing the transfer (eg Chrome, µTorrent, etc.), the numbers are in line with the expected values at the same time that bandwidth monitoring programs are showing the high numbers. The only significant change (and pretty much the only change at all) that has occurred to my system since the change was the installation of SP1 for Windows 7. As such, it is my belief that some sort of change exists in SP1 whereby software that accesses the bandwidth via a specific API receives (erroneously?) high numbers while others that have access to the raw data continue to receive the correct values. I booted into Windows XP and downloaded some things via HTTP and torrent and in both cases, the numbers were as expected (like they were in Windows 7 before installing SP1). I then booted back into 7SP1 and once again, the numbers were four times higher than possible. Therefore it is definitely something in SP1 that has changed how local bandwidth is calculated/returned. There is definitely something wonky with Windows 7 SP1’s network speed calculation. I tried Googling this, but (for multiple reasons), have had a difficult time finding anything relevant. Has anybody else noticed this behavior? Does anybody know of any bugs or changes in SP1 that could account for it?

  • SignalR Server Error "The ConnectionId is in the incorrect format." with SignalR-ObjC Library

    - by ozzotto
    Before asking a separate question I've done lots of googling about it and added a comment in the already existing stackoverflow question. I have a SignalR Hub (tried both v. 1.1.3 and 2.0.0-rc) in my server with the below code: [HubName("TestHub")] public class TestHub : Hub { [Authorize] public void TestMethod(string test) { //some stuff here Clients.Caller.NotifyOnTestCompleted(); } } The problem persists if I remove the Authorize attribute. And in my iOS client I try to call it with the below code: SRHubConnection *hubConnection = [SRHubConnection connectionWithURL:_baseURL]; SRHubProxy *hubProxy = [hubConnection createHubProxy:@"TestHub"]; [hubProxy on:@"NotifyOnTestCompleted" perform:self selector:@selector(stopConnection)]; hubConnection.started = ^{ [hubProxy invoke:@"TestMethod" withArgs:@[@"test"]]; }; //received, error handling [hubConnection start]; When the app starts the user is not logged in and there is no open SignalR connection. The users logs in by calling a Login service in the server which makes use of WebSecurity.Login method. If the login service returns success I then make the above call to SignalR Hub and I get the server error 500 with description "The ConnectionId is in the incorrect format.". The full server stacktrace is the following: Exception information: Exception type: InvalidOperationException Exception message: The ConnectionId is in the incorrect format. at Microsoft.AspNet.SignalR.PersistentConnection.GetConnectionId(HostContext context, String connectionToken) at Microsoft.AspNet.SignalR.PersistentConnection.ProcessRequest(HostContext context) at Microsoft.AspNet.SignalR.Hubs.HubDispatcher.ProcessRequest(HostContext context) at Microsoft.AspNet.SignalR.PersistentConnection.ProcessRequest(IDictionary`2 environment) at Microsoft.Owin.Mapping.MapMiddleware.<Invoke>d__0.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at Microsoft.Owin.Host.SystemWeb.IntegratedPipeline.IntegratedPipelineContext.EndFinalWork(IAsyncResult ar) at System.Web.HttpApplication.AsyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Request information: Request URL: http://myserverip/signalr/signalr/connect?transport=webSockets&connectionToken=axJs EQMZxpmUopL36owSUkdhNs85E0fyB2XvV5R5znZfXYI/CiPbTRQ3kASc3 mq60cLkZU7coYo1P fbC0U1LR2rI6WIvCNIMOmv/mHut/Unt9mX3XFkQb053DmWgCan5zHA==&connectionData=[{"Name":"testhub"}] Request path: /signalr/signalr/connect User host address: User: Is authenticated: False Authentication Type: Thread account name: IIS APPPOOL\DefaultAppPool Thread information: Thread ID: 14 Thread account name: IIS APPPOOL\DefaultAppPool Is impersonating: True Stack trace: at Microsoft.AspNet.SignalR.PersistentConnection.GetConnectionId(HostContext context, String connectionToken) at Microsoft.AspNet.SignalR.PersistentConnection.ProcessRequest(HostContext context) at Microsoft.AspNet.SignalR.Hubs.HubDispatcher.ProcessRequest(HostContext context) at Microsoft.AspNet.SignalR.PersistentConnection.ProcessRequest(IDictionary`2 environment) at Microsoft.Owin.Mapping.MapMiddleware.<Invoke>d__0.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at Microsoft.Owin.Host.SystemWeb.IntegratedPipeline.IntegratedPipelineContext.EndFinalWork(IAsyncResult ar) at System.Web.HttpApplication.AsyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) I understand this is some kind of authentication and user identity mismatching but up to now I have found no way of solving it. All other questions suggest stoping the opened connection when the user identity changes but as I mentioned above I have no open connection before the user logs in successfully. Any help would be much appreciated. Thank you.

  • View overlapping with RelativeLayout on Android 1.5

    - by Justin
    I am having a problem with views overlapping in a RelativeLayout on Android 1.5... Everything is working fine on Android 1.6 and above. I do understand that Android 1.5 has some issues with RelativeLayout, but I was not able to find anything on StackOverflow or the android beginners group for my specific problem. My layout consists of four sections, each of which are made up of a TextView, a Gallery, and another TextView aligned vertically: Running Apps Recent Apps Services Processes When all four sets of these items are displayed everything works fine. However, my app allows the user to specify that some of these are not displayed. If the user turns off Running Apps, Recent Apps, or Services then the remaining sections all of a sudden overlap eachother. Here is my code for the layout. I'm not sure what I am doing wrong. When the user turns off display of a section I use the View.GONE visibility setting: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center_vertical" android:layout_gravity="center_vertical" android:background="@null" > <!-- Running Gallery View Items --> <TextView style="@style/TitleText" android:id="@+id/running_gallery_title_text_id" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="left" android:paddingLeft="1sp" android:paddingRight="10sp" android:text="@string/running_title" /> <Gallery android:id="@+id/running_gallery_id" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/running_gallery_title_text_id" android:spacing="5sp" android:clipChildren="false" android:clipToPadding="false" android:unselectedAlpha=".5" /> <TextView style="@style/SubTitleText" android:id="@+id/running_gallery_current_text_id" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/running_gallery_id" android:gravity="center_horizontal" /> <!-- Recent Gallery View Items --> <TextView style="@style/TitleText" android:id="@+id/recent_gallery_title_text_id" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/running_gallery_current_text_id" android:gravity="left" android:paddingLeft="1sp" android:paddingRight="10sp" android:text="@string/recent_title" /> <Gallery android:id="@+id/recent_gallery_id" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/recent_gallery_title_text_id" android:spacing="5sp" android:clipChildren="false" android:clipToPadding="false" android:unselectedAlpha=".5" /> <TextView style="@style/SubTitleText" android:id="@+id/recent_gallery_current_text_id" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/recent_gallery_id" android:gravity="center_horizontal" /> <!-- Service Gallery View Items --> <TextView style="@style/TitleText" android:id="@+id/service_gallery_title_text_id" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/recent_gallery_current_text_id" android:gravity="left" android:paddingLeft="1sp" android:paddingRight="10sp" android:text="@string/service_title" /> <Gallery android:id="@+id/service_gallery_id" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/service_gallery_title_text_id" android:spacing="5sp" android:clipChildren="false" android:clipToPadding="false" android:unselectedAlpha=".5" /> <TextView style="@style/SubTitleText" android:id="@+id/service_gallery_current_text_id" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/service_gallery_id" android:gravity="center_horizontal" /> </RelativeLayout> I ommitted the xml for the Processes section in a (somewhat vain) attempt to keep this shorter... What can I do to make this work in Android 1.5? I don't think it is just a matter of reordering the views in the xml because it works fine when everything is displayed.

  • Json.Net Issues: StackOverflowException is thrown when serialising circular dependent ISerializable object with ReferenceLoopHandling.Ignore

    - by keyr
    I have a legacy application that used binary serialisation to persist the data. Now we wanted to use Json.net 4.5 to serialise the data without much changes to the existing classes. Things were working nice till we hit a circular dependent class. Is there any workaround to solve this problem? Sample code as shown below [Serializable] class Department : ISerializable { public Employee Manager { get; set; } public string Name { get; set; } public Department() { } public Department( SerializationInfo info, StreamingContext context ) { Manager = ( Employee )info.GetValue( "Manager", typeof( Employee ) ); Name = ( string )info.GetValue( "Name", typeof( string ) ); } public void GetObjectData( SerializationInfo info, StreamingContext context ) { info.AddValue( "Manager", Manager ); info.AddValue( "Name", Name ); } } [Serializable] class Employee : ISerializable { [NonSerialized] //This does not work [XmlIgnore]//This does not work private Department mDepartment; public Department Department { get { return mDepartment; } set { mDepartment = value; } } public string Name { get; set; } public Employee() { } public Employee( SerializationInfo info, StreamingContext context ) { Department = ( Department )info.GetValue( "Department", typeof( Department ) ); Name = ( string )info.GetValue( "Name", typeof( string ) ); } public void GetObjectData( SerializationInfo info, StreamingContext context ) { info.AddValue( "Department", Department ); info.AddValue( "Name", Name ); } } And the test code Department department = new Department(); department.Name = "Dept1"; Employee emp1 = new Employee { Name = "Emp1", Department = department }; department.Manager = emp1; Employee emp2 = new Employee() { Name = "Emp2", Department = department }; IList<Employee> employees = new List<Employee>(); employees.Add( emp1 ); employees.Add( emp2 ); var memoryStream = new MemoryStream(); var formatter = new BinaryFormatter(); formatter.Serialize( memoryStream, employees ); memoryStream.Seek( 0, SeekOrigin.Begin ); IList<Employee> deserialisedEmployees = formatter.Deserialize( memoryStream ) as IList<Employee>; //Works nicely JsonSerializerSettings jsonSS= new JsonSerializerSettings(); jsonSS.TypeNameHandling = TypeNameHandling.Objects; jsonSS.TypeNameAssemblyFormat = FormatterAssemblyStyle.Full; jsonSS.Formatting = Formatting.Indented; jsonSS.ReferenceLoopHandling = ReferenceLoopHandling.Ignore; //This is not working!! //jsonSS.ReferenceLoopHandling = ReferenceLoopHandling.Serialize; //This is also not working!! jsonSS.PreserveReferencesHandling = PreserveReferencesHandling.All; string jsonAll = JsonConvert.SerializeObject( employees, jsonSS ); //Throws stackoverflow exception Edit1: The issue has been reported to Json (http://json.codeplex.com/workitem/23668)

  • Python soap using soaplib (server) and suds (client)

    - by Celso Axelrud
    This question is related to: http://stackoverflow.com/questions/1751027/python-soap-server-client In the case of soap with python, there are recommendation to use soaplib (http://wiki.github.com/jkp/soaplib) as soap server and suds (https://fedorahosted.org/suds/) as soap client. My target is to create soap services in python that can be consumed by several clients (java, etc). I tried the HelloWorld example from soaplib (http://trac.optio.webfactional.com/wiki/HelloWorld). It works well when the client is also using soaplib. Then, I tried to use suds as client consuming the HelloWorld services and it fail. -Why this is happening? Does soaplib server has problems to consumed by different clients? Here the code for the server: from soaplib.wsgi_soap import SimpleWSGISoapApp from soaplib.service import soapmethod from soaplib.serializers.primitive import String, Integer, Arraycode class HelloWorldService(SimpleWSGISoapApp): @soapmethod(String,Integer,_returns=Array(String)) def say_hello(self,name,times): results = [] for i in range(0,times): results.append('Hello, %s'%name) return results if __name__=='__main__': from cherrypy.wsgiserver import CherryPyWSGIServer #from cherrypy._cpwsgiserver import CherryPyWSGIServer # this example uses CherryPy2.2, use cherrypy.wsgiserver.CherryPyWSGIServer for CherryPy 3.0 server = CherryPyWSGIServer(('localhost',7789),HelloWorldService()) server.start() This is the soaplib client: from soaplib.client import make_service_client from SoapServerTest_1 import HelloWorldService client = make_service_client('http://localhost:7789/',HelloWorldService()) print client.say_hello("Dave",5) Results: >>> ['Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave'] This is the suds client: from suds.client import Client url = 'http://localhost:7789/HelloWordService?wsdl' client1 = Client(url) client1.service.say_hello("Dave",5) Results: >>> Unhandled exception while debugging...

  • after return PartialView() Url.Actionlink("Action", "Controller"), the Controller is lost

    - by Johannes
    Well the Question is related to a problem I posted before (http://stackoverflow.com/questions/2403899/asp-net-mvc-partial-view-does-not-call-my-action). In practice I've a partial view which contains a Form, after submitting the Form the Controller returns the Partial View. Well the Problem is if I reload the page which contains the partial view the function <%= Url.Action("ChangePassword", "Account") %> returns "Account/ChangePassword", if I submit the form and the partial is returned by the controller. Using return PartialView() the function <%= Url.Action("ChangePassword", "Account") %> returns only "ChangePassword". Any Idea because? The View looks like: <form action="<%= Url.Action("ChangePassword", "Account") %>" method="post" id="jform"> <div> <fieldset> <legend>Account Information</legend> <p> <label for="currentPassword">Current password:</label> <%= Html.Password("currentPassword") %> <%= Html.ValidationMessage("currentPassword") %> </p> <p> <label for="newPassword">New password:</label> <%= Html.Password("newPassword") %> <%= Html.ValidationMessage("newPassword") %> </p> <p> <label for="confirmPassword">Confirm new password:</label> <%= Html.Password("confirmPassword") %> <%= Html.ValidationMessage("confirmPassword") %> </p> <p> <input type="submit" value="Change Password" /> </p> </fieldset> </div> </form> </div> <script> $(function() { $('#jform').submit(function() { $('#jform').ajaxSubmit({ target: '#FmChangePassword' }); return false; }); }); </script> Part of the Controller: if (!ValidateChangePassword(currentPassword, newPassword, confirmPassword)) { return PartialView(ViewData); }

  • Get Local IP-Address using Boost.Asio

    - by MOnsDaR
    Hey, I'm currently searching for a portable way of getting the local IP-addresses. Because I'm using Boost anyway I thought it would be a good idea to use Boost.Asio for this task. There are serveral examples on the net which should do the trick. Examples: Official Boost.Asio Documentation Some Asian Page I tried both codes with just slight modifications. The Code on Boost.Doc was changed to not resolve "www.boost.org" but "localhost" or my hostname instead. For getting the hostname I used boost::asio::ip::host_name() or typed it directly as a string. Additionally I wrote my own code which was a merge of the above examples and my (little) knowledge I gathered from the Boost Documentation and other examples. All the sources worked, but they did just return the following IP: 127.0.1.1 (Thats not a typo, its .1.1 at the end) I run and compiled the code on Ubuntu 9.10 with GCC 4.4.1 A colleague tried the same code on his machine and got 127.0.0.2 (Not a typo too...) He compiled and run on Suse 11.0 with GCC 4.4.1 (I'm not 100% sure) I don't know if it is possible to change the localhost (127.0.0.1), but I know that neither me or my colleague did it. ifconfig says loopback uses 127.0.0.1. ifconfig also finds the public IP I am searching for (141.200.182.30 in my case, subnet is 255.255.0.0) So is this a Linux-issue and the code is not as portable as I thought? Do I have to change something else or is Boost.Asio not working as a solution for my problem at all? I know there are much questions about similar topics on Stackoverflow and other pages, but I cannot find information which is useful in my case. If you got useful links, it would be nice if you could point me to it. Thanks in advance, MOnsDaR PS: Here is the modified code I used from Boost.Doc: #include <boost/asio.hpp> using boost::asio::ip::tcp; boost::asio::io_service io_service; tcp::resolver resolver(io_service); tcp::resolver::query query(boost::asio::ip::host_name(), ""); tcp::resolver::iterator iter = resolver.resolve(query); tcp::resolver::iterator end; // End marker. while (iter != end) { tcp::endpoint ep = *iter++; std::cout << ep << std::endl; }

  • Python Memory leak - Solved, but still puzzled

    - by disappearedng
    Dear everyone, I have successfully debugged my own memory leak problems. However, I have noticed some very strange occurence. for fid, fv in freqDic.iteritems(): outf.write(fid+"\t") #ID for i, term in enumerate(domain): #Vector tfidf = self.tf(term, fv) * self.idf( term, docFreqDic) if i == len(domain) - 1: outf.write("%f\n" % tfidf) else: outf.write("%f\t" % tfidf) outf.flush() print "Memory increased by", int(self.memory_mon.usage()) - startMemory outf.close() def tf(self, term, freqVector): total = freqVector[TOTAL] if total == 0: return 0 if term not in freqVector: ## When you don't have these lines memory leaks occurs return 0 ## return float(freqVector[term]) / freqVector[TOTAL] def idf(self, term, docFrequencyPerTerm): if term not in docFrequencyPerTerm: return 0 return math.log( float(docFrequencyPerTerm[TOTAL])/docFrequencyPerTerm[term]) Basically let me describe my problem: 1) I am doing tfidf calculations 2) I traced that the source of memory leaks is coming from defaultdict. 3) I am using the memory_mon from http://stackoverflow.com/questions/276052/how-to-get-current-cpu-and-ram-usage-in-python 4) The reason for my memory leaks is as follows: a) in self.tf, if the lines: if term not in freqVector: return 0 are not added that will cause the memory leak. (I verified this myself using memory_mon and noticed a sharp increase in memory that kept on increasing) The solution to my problem was 1) since fv is a defaultdict, any reference to it that are not found in fv will create an entry. Over a very large domain, this will cause memory leaks. I decided to use dict instead of default dict and the memory problem did go away. My only puzzle is: since fv is created in "for fid, fv in freqDic.iteritems():" shouldn't fv be destroyed at the end of every for loop? I tried putting gc.collect() at the end of the for loop but gc was not able to collect everything (returns 0). Yes, the hypothesis is right, but the memory should stay fairly consistent with ever for loop if for loops do destroy all temp variables. This is what it looks like with that two line in self.tf: Memory increased by 12 Memory increased by 948 Memory increased by 28 Memory increased by 36 Memory increased by 36 Memory increased by 32 Memory increased by 28 Memory increased by 32 Memory increased by 32 Memory increased by 32 Memory increased by 40 Memory increased by 32 Memory increased by 32 Memory increased by 28 and without the the two line: Memory increased by 1652 Memory increased by 3576 Memory increased by 4220 Memory increased by 5760 Memory increased by 7296 Memory increased by 8840 Memory increased by 10456 Memory increased by 12824 Memory increased by 13460 Memory increased by 15000 Memory increased by 17448 Memory increased by 18084 Memory increased by 19628 Memory increased by 22080 Memory increased by 22708 Memory increased by 24248 Memory increased by 26704 Memory increased by 27332 Memory increased by 28864 Memory increased by 30404 Memory increased by 32856 Memory increased by 33552 Memory increased by 35024 Memory increased by 36564 Memory increased by 39016 Memory increased by 39924 Memory increased by 42104 Memory increased by 42724 Memory increased by 44268 Memory increased by 46720 Memory increased by 47352 Memory increased by 48952 Memory increased by 50428 Memory increased by 51964 Memory increased by 53508 Memory increased by 55960 Memory increased by 56584 Memory increased by 58404 Memory increased by 59668 Memory increased by 61208 Memory increased by 62744 Memory increased by 64400 I look forward to your answer

  • How to configure Hudson and git plugin with an SSH key

    - by jlpp
    I've got Hudson (continuous integration system) with the git plugin running on a Tomcat Windows Service. msysgit is installed and the msysgit bin dir is in the path. PuTTY/Pageant/plink are installed and msysgit is configured to use them. When I run a job that attempts to clone the git repository I get the following error: $ git clone -o origin git@hostname:project.git "e:\HUDSON_HOME\jobs\Project Trunk\workspace" ERROR: Error cloning remote repo 'origin' : Could not clone git@hostname:project.git ERROR: Cause: Error performing git clone -o origin git@hostname:project.git e:\HUDSON_HOME\jobs\Project Trunk\workspace Trying next repository ERROR: Could not clone from a repository FATAL: Could not clone hudson.plugins.git.GitException: Could not clone Running git clone -o origin git@hostname:project.git "e:\HUDSON_HOME\jobs\Project Trunk\workspace" from the command line works without error. I've confirmed that my issue is not the same as http://stackoverflow.com/questions/1177292/hudson-git-clone-error because git is in the path and I don't get any error about the git executable on Hudson's Configure System page. This leads me to believe that the problem is that the user who owns the Tomcat/Hudson Windows service (Local System) has no SSH key set up to be able to clone the git repository. My question is, how can I set things up so that the git plugin/msysgit know to use a particular SSH key when trying to clone? I don't think Pageant will work because the Tomcat service is running as the "Local System" user, but I may be wrong. I have tried setting Pageant up as a service (using runassvc.exe), passing the appropriate key, and having it run as "Local System". The Tomcat/Hudson service doesn't seem to be able to see the key from the pageant service. Are there any other techniques for setting up a key? Thanks. EDIT: The discussion on http://n4.nabble.com/Hudson-with-git-and-ssh-td375633.html shows that someone else had a similar question. ssh-agent was suggested and this tool does come with msysgit but I'm not sure how to use it in conjunction with the Hudson service. Still, good clue if anyone can fill in the gaps. Thanks to Peter for the comment with the link. Also, the discussion on http://n4.nabble.com/questions-about-git-and-github-plug-ins-td383420.html starts off with the same question. I'm trying to resurrect that thread.

  • How to change Jquery UI Slider handle

    - by Tom
    I want to modify the stock JQuery UI slider so that the handle has a arrow on it rather than being a square. i.e. I want to use a custom image as the handle. There are a few tutorials that do it: http://jqueryfordesigners.com/slider-gallery/ http://www.ryancoughlin.com/2008/11/04/using-the-jquery-ui-slider/ http://www.keepthewebweird.com/creating-a-nice-slider-with-jquery-ui/ But I can't get it to work. The following code results in a stationary handle image: <!DOCTYPE html> <html> <head> <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" /> <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.slider.js"></script> <style type="text/css"> #myhandle {position: absolute;z-index: 100;height: 25px;width: 35px;top: auto;background: url(http://stackoverflow.com/content/img/so/vote-arrow-down.png) no-repeat;} </style> <script type="text/javascript"> $(document).ready(function(){ $("#slider").slider({handle: '#myhandle'}); }); </script> </head> <body> <div id="slider"><div id="myhandle"></div></div> </body> </html> It is as if JQuery doesn't pick up that I want to use the myhandle id for the handle. I'm wondering: Do I need a plugin for JQuery to recognise the handle option? (it is not documented in http://docs.jquery.com/UI/Slider). Or perhaps it only worked in an old version of JQuery? Any ideas?

  • ADO.NET Data Services Entity Framework request error when property setter is internal

    - by Jim Straatman
    I receive an error message when exposing an ADO.NET Data Service using an Entity Framework data model that contains an entity (called "Case") with an internal setter on a property. If I modify the setter to be public (using the entity designer), the data services works fine. I don’t need the entity "Case" exposed in the data service, so I tried to limit which entities are exposed using SetEntitySetAccessRule. This didn’t work, and service end point fails with the same error. public static void InitializeService(IDataServiceConfiguration config) { config.SetEntitySetAccessRule("User", EntitySetRights.AllRead); } The error message is reported in a browser when the .svc endpoint is called. It is very generic, and reads “Request Error. The server encountered an error processing the request. See server logs for more details.” Unfortunately, there are no entries in the System and Application event logs. I found this stackoverflow question that shows how to configure tracing on the service. After doing so, the following NullReferenceExceptoin error was reported in the trace log. Does anyone know how to avoid this exception when including an entity with an internal setter?

  • Howto - Running Redmine on mongrel as a service on windows

    - by Achilles
    I use Redmine on Mongrel as a project manager and I use a batch file (start-redmine.bat) to start the redmine in mongrel. There are 2 issues with my setup: 1. I have a running IIS on the server that occupies the HTTP port (80) 2. The start-redmine.bat must be periodically checked to see if it's stopped after a restart that is caused by windows update service. for the first issue, I have no choice but running mongrel on a port like 3000 and for the second issue I have to create a windows service that runs automatically in the background when the windows starts; and here comes the trouble! There are at least 3 ways to run redmine as a service that I'm aware of; none of them can satisfy a performance view on this subject. you may read about them on http://stackoverflow.com/questions/877943/how-to-configure-a-rails-app-redmine-to-run-as-a-service-on-windows I tried them all. The easiest way to setup such a service is using mongrel_service approach; in 3 lines of command you're done. but the performance is significantly lower than running that batch file... Now, I wanna show you my approach: First suppose we have ruby installed into c:\ruby and we have issued the command gem install mongrel to get the mongrel gem installed into c:\ruby\bin Also, suppose we have installed the Redmine into a folder like c:\redmine; and we have ruby's path (i.e. c:\ruby\bin) in our PATH environment variable. Now Download and install the Windows NT Resource Kit Tools from microsoft website. Open the command-line tool that comes with the Resource Kit (from start menu). Use instsrv to install a dummy service called Redmine using the following command: "[path-to-instsrv.exe]\instsrv" Redmine "[path-to-srvany.exe]\srvany.exe" in my case (which is the default case) it was something like this: "C:\Program Files\Windows Resource Kits\Tools\instsrv" Redmine "C:\Program Files\Windows Resource Kits\Tools\srvany.exe" Now create the batch file. Open a notepad and paste these instructions into it and then save it as "c:\redmine\start-redmine.bat" @echo off cd c:\redmine\ mongrel_rails start -a 0.0.0.0 -p 3000 -e production Now we need to configure that dummy service we had created before. WATCH OUT WHAT YOU'RE DOING FROM HERE ON, OR YOU MAY CORRUPT YOUR WINDOWS. To configure that service, open windows registry editor (Start - Run - regedit) and navigate to this node: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Redmine Right-Click on "Redmine" node and using the context menu, create a new key called Parameters (New - Key) Right-Click on "Parameters" and create a String Value property called Application. Do this again and create another String Value called AppParameters. Now Double-click on "Application" and put cmd.exe into "Value data" section. Then Double-click on "AppParameters" and put /C "C:\redmine\start-redmine.bat" into Value data section. We're done! issue this command to run the redmine on mongrel as a service: net start Redmine

  • How to troubleshoot a 'System.Management.Automation.CmdletInvocationException'

    - by JamesD
    Does anyone know how best to determine the specific underlying cause of this exception? Consider a WCF service that is supposed to use Powershell 2.0 remoting to execute MSBuild on remote machines. In both cases the scripting environments are being called in-process (via C# for Powershell and via Powershell for MSBuild), rather than 'shelling-out' - this was a specific design decision to avoid command-line hell as well as to enable passing actual objects into the Powershell script. The Powershell script that calls MSBuild is shown below: function Run-MSBuild { [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Build.Engine") $engine = New-Object Microsoft.Build.BuildEngine.Engine $engine.BinPath = "C:\Windows\Microsoft.NET\Framework\v3.5" $project = New-Object Microsoft.Build.BuildEngine.Project($engine, "3.5") $project.Load("deploy.targets") $project.InitialTargets = "DoStuff" # # Set some initial Properties & Items # # Optionally setup some loggers (have also tried it without any loggers) $consoleLogger = New-Object Microsoft.Build.BuildEngine.ConsoleLogger $engine.RegisterLogger($consoleLogger) $fileLogger = New-Object Microsoft.Build.BuildEngine.FileLogger $fileLogger.Parameters = "verbosity=diagnostic" $engine.RegisterLogger($fileLogger) # Run the build - this is the line that throws a CmdletInvocationException $result = $project.Build() $engine.Shutdown() } When running the above script from a PS command prompt it all works fine. However, as soon as the script is executed from C# it fails with the above exception. The C# code being used to call Powershell is shown below (remoting functionality removed for simplicity's sake): // Build the DTO object that will be passed to Powershell dto = SetupDTO() RunspaceConfiguration runspaceConfig = RunspaceConfiguration.Create(); using (Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfig)) { runspace.Open(); IList errors; using (var scriptInvoker = new RunspaceInvoke(runspace)) { // The Powershell script lives in a file that gets compiled as an embedded resource TextReader tr = new StreamReader(Assembly.GetExecutingAssembly().GetManifestResourceStream("MyScriptResource")); string script = tr.ReadToEnd(); // Load the script into the Runspace scriptInvoker.Invoke(script); // Call the function defined in the script, passing the DTO as an input object var psResults = scriptInvoker.Invoke("$input | Run-MSBuild", dto, out errors); } } Assuming that the issue was related to MSBuild outputting something that the Powershell runspace can't cope with, I have also tried the following variations to the second .Invoke() call: var psResults = scriptInvoker.Invoke("$input | Run-MSBuild | Out-String", dto, out errors); var psResults = scriptInvoker.Invoke("$input | Run-MSBuild | Out-Null", dto, out errors); var psResults = scriptInvoker.Invoke("Run-MSBuild | Out-String"); var psResults = scriptInvoker.Invoke("Run-MSBuild | Out-String"); var psResults = scriptInvoker.Invoke("Run-MSBuild | Out-Null"); I've also looked at using a custom PSHost (based on this sample: http://blogs.msdn.com/daiken/archive/2007/06/22/hosting-windows-powershell-sample-code.aspx), but during debugging I was unable to see any 'interesting' calls to it being made. Do the great and the good of Stackoverflow have any insight that might save my sanity?

  • How to track deleted self-tracking entities in ObservableCollection without memory leaks

    - by Yannick M.
    In our multi-tier business application we have ObservableCollections of Self-Tracking Entities that are returned from service calls. The idea is we want to be able to get entities, add, update and remove them from the collection client side, and then send these changes to the server side, where they will be persisted to the database. Self-Tracking Entities, as their name might suggest, track their state themselves. When a new STE is created, it has the Added state, when you modify a property, it sets the Modified state, it can also have Deleted state but this state is not set when the entity is removed from an ObservableCollection (obviously). If you want this behavior you need to code it yourself. In my current implementation, when an entity is removed from the ObservableCollection, I keep it in a shadow collection, so that when the ObservableCollection is sent back to the server, I can send the deleted items along, so Entity Framework knows to delete them. Something along the lines of: protected IDictionary<int, IList> DeletedCollections = new Dictionary<int, IList>(); protected void SubscribeDeletionHandler<TEntity>(ObservableCollection<TEntity> collection) { var deletedEntities = new List<TEntity>(); DeletedCollections[collection.GetHashCode()] = deletedEntities; collection.CollectionChanged += (o, a) => { if (a.OldItems != null) { deletedEntities.AddRange(a.OldItems.Cast<TEntity>()); } }; } Now if the user decides to save his changes to the server, I can get the list of removed items, and send them along: ObservableCollection<Customer> customers = MyServiceProxy.GetCustomers(); customers.RemoveAt(0); MyServiceProxy.UpdateCustomers(customers); At this point the UpdateCustomers method will verify my shadow collection if any items were removed, and send them along to the server side. This approach works fine, until you start to think about the life-cycle these shadow collections. Basically, when the ObservableCollection is garbage collected there is no way of knowing that we need to remove the shadow collection from our dictionary. I came up with some complicated solution that basically does manual memory management in this case. I keep a WeakReference to the ObservableCollection and every few seconds I check to see if the reference is inactive, in which case I remove the shadow collection. But this seems like a terrible solution... I hope the collective genius of StackOverflow can shed light on a better solution. Thanks!

  • How do I diagnose "Microsoft .NET ClickOnce Launch Utility has stopped working"?

    - by Xaero
    Hello StackOverflow! We deploy our application using ClickOnce, installed from a file path. For 24 versions it has been working perfectly - now, on version 25 I get the following error once the application has installed and it launches: If I test a previous deployment on the same machine, it works. Where can I even begin to look to find the cause of this error? I already checked the windows event logs - nothing. EDIT: I noticed that while the dialog is displayed, a temporary xml file 'WER561D.tmp.WERInternalMetadata.xml' is generated in my temp folder.

  • MSSQL: How to copy a file (pdf, doc, txt...) stored in a varbinary(max) field to a file in a CLR sto

    - by user193655
    I ask this question as a followup of this question. A solution that uses bcp and xp_cmdshell, that is not my desired solution, has been posted here: stackoverflow.com/questions/828749/ms-sql-server-2005-write-varbinary-to-file-system (sorry i cannot post a second hyperlink since my reputation is les than 10). I am new to c# (since I am a Delphi developer) anyway I was able to create a simple CLR stored procedures by following a tutorial. My task is to move a file from the client file system to the server file system (the server can be accessed using remote IP, so I cannot use a shared folder as destination, this is why I need a CLR stored procedure). So I plan to: 1) store from Delphi the file in a varbinary(max) column of a temporary table 2) call the CLR stored procedure to create a file at the desired path using the data contained in the varbinary(max) field Imagine I need to move C:\MyFile.pdf to Z:\MyFile.pdf, where C: is a harddrive on local system and Z: is an harddrive on the server. I provide the code below (not working) that someone can modify to make it work? Here I suppose to have a table called MyTable with two fields: ID (int) and DATA (varbinary(max)). Please note it doesn't make a difference if the table is a real temporary table or just a table where I temporarly store the data. I would appreciate if some exception handling code is there (so that I can manage an "impossible to save file" exception). I would like to be able to write a new file or overwrite the file if already existing. [Microsoft.SqlServer.Server.SqlProcedure] public static void VarbinaryToFile(int TableId) { using (SqlConnection connection = new SqlConnection("context connection=true")) { connection.Open(); SqlCommand command = new SqlCommand("select data from mytable where ID = @TableId", connection); command.Parameters.AddWithValue("@TableId", TableId); // This was the sample code I found to run a query //SqlContext.Pipe.ExecuteAndSend(command); // instead I need something like this (THIS IS META_SYNTAX!!!): SqlContext.Pipe.ResultAsStream.SaveToFile('z:\MyFile.pdf'); } } (one subquestion is: is this approach coorect or there is a way to directly pass the data to the CLR stored procedure so I don't need to use a temp table?) If the subquestion's answer is No, could you describe the approach of avoiding a temp table? So is there a better way then the one I describe above (=temp table + Stored procedure)? A way to directly pass the dataastream from the client application to the CLR stored procedure? (my files can be any size but also very big)

  • Reading a POP3 server with only TcpClient and StreamWriter/StreamReader[SOLVED]

    - by WebDevHobo
    I'm trying to read mails from my live.com account, via the POP3 protocol. I've found the the server is pop3.live.com and the port if 995. I'm not planning on using a pre-made library, I'm using NetworkStream and StreamReader/StreamWriter for the job. I need to figure this out. So, any of the answers given here: http://stackoverflow.com/questions/44383/reading-email-using-pop3-in-c are not usefull. It's part of a larger program, but I made a small test to see if it works. Eitherway, i'm not getting anything. Here's the code I'm using, which I think should be correct. EDIT: this code is old, please refer to the second block problem solved. public Program() { string temp = ""; using(TcpClient tc = new TcpClient(new IPEndPoint(IPAddress.Parse("127.0.0.1"),8000))) { tc.Connect("pop3.live.com",995); using(NetworkStream nws = tc.GetStream()) { using(StreamReader sr = new StreamReader(nws)) { using(StreamWriter sw = new StreamWriter(nws)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); while(temp != ".") { temp += sr.ReadLine(); } } } } } Console.WriteLine(temp); } Visual Studio debugger constantly falls over tc.Connect("pop3.live.com",995); Which throws an "A socket operation was attempted to an unreachable network 65.55.172.253:995" error. So, I'm sending from port 8000 on my machine to port 995, the hotmail pop3 port. And I'm getting nothing, and I'm out of ideas. Second block: Problem was apparently that I didn't write the quit command. The Code: public Program() { string str = string.Empty; string strTemp = string.Empty; using(TcpClient tc = new TcpClient()) { tc.Connect("pop3.live.com",995); using(SslStream sl = new SslStream(tc.GetStream())) { sl.AuthenticateAsClient("pop3.live.com"); using(StreamReader sr = new StreamReader(sl)) { using(StreamWriter sw = new StreamWriter(sl)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); sw.WriteLine("QUIT "); sw.Flush(); while((strTemp = sr.ReadLine()) != null) { if(strTemp == "." || strTemp.IndexOf("-ERR") != -1) { break; } str += strTemp; } } } } } Console.WriteLine(str); }

  • What .Net Namespace contains Entity for use in a generic repository?

    - by Sara
    I have a question that I'm ashamed to ask, but I'm going to have a go at it anyway. I am creating a generic repository in asp.net mvc. I came across an example on this website which I find to be exactly what I was looking for, but there is one problem. It references an object - Entity - and I don't know what namespace it is in. I typically create my repositories and use Entity Framework but I decided to use a generic repository because I am using the same code in multiple projects over and over again. Here is the code: public interface IRepository { void Save(ENTITY entity) where ENTITY : Entity; void Delete<ENTITY>(ENTITY entity) where ENTITY : Entity; ENTITY Load<ENTITY>(int id) where ENTITY : Entity; IQueryable<ENTITY> Query<ENTITY>() where ENTITY : Entity; IList<ENTITY> GetAll<ENTITY>() where ENTITY : Entity; IQueryable<ENTITY> Query<ENTITY>(IDomainQuery<ENTITY> whereQuery) where ENTITY : Entity; ENTITY Get<ENTITY>(int id) where ENTITY : Entity; IList<ENTITY> GetObjectsForIds<ENTITY>(string ids) where ENTITY : Entity; void Flush(); } Can someone please tell me what namespace Entity is in? As you can tell, a constraint is placed on the code so that it must be an Entity type. I know that there is an Entity in System.Data.Entity, but that isn't what I need. I have had instances before where I was looking for some namespace that took me forever to find, but I have searched and I'm unable to find the appropriate namespace to cast my generic items correctly. I could cast it as a class and be done with it, but it is bugging me that I can't find Entity anywhere. Can someone help me....please..... :-) Here is a link to the original post. http://stackoverflow.com/questions/1472719/asp-net-mvc-how-many-repositories

  • NSString drawAtPoint Crash on the iPhone (NSString drawAtPoint)

    - by Kyle
    Hey. I have a very simple text output to buffer system which will crash randomly. It will be fine for DAYS, then sometimes it'll crash a few times in a few minutes. The callstack is almost exactly the same for other guys who use higher level controls: http://discussions.apple.com/thread.jspa?messageID=7949746 http://stackoverflow.com/questions/1978997/iphone-app-crashed-assertion-failed-function-evictglyphentryfromstrike-file It crashes at the line (below as well in drawTextToBuffer()): [nsString drawAtPoint:CGPointMake(0, 0) withFont:clFont]; I have the same call of "evict_glyph_entry_from_cache" with the abort calls immediately following it. Apparently it happens to other people. I can say that my NSString* is perfectly fine at the time of the crash. I can read the text from the debugger just fine. static CGColorSpaceRef curColorSpace; static CGContextRef myContext; static float w, h; static int iFontSize; static NSString* sFontName; static UIFont* clFont; static int iLineHeight; unsigned long* txb; /* 256x256x4 Buffer */ void selectFont(int iSize, NSString* sFont) { iFontSize = iSize; clFont = [UIFont fontWithName:sFont size:iFontSize]; iLineHeight = (int)(ceil([clFont capHeight])); } void initText() { w = 256; h = 256; txb = (unsigned long*)malloc_(w * h * 4); curColorSpace = CGColorSpaceCreateDeviceRGB(); myContext = CGBitmapContextCreate(txb, w, h, 8, w * 4, curColorSpace, kCGImageAlphaPremultipliedLast); selectFont(12, @"Helvetica"); } void drawTextToBuffer(NSString* nsString) { CGContextSaveGState(myContext); CGContextSetRGBFillColor(myContext, 1, 1, 1, 1); UIGraphicsPushContext(myContext); /* This line will crash. It crashes even with constant Strings.. At the time of the crash, the pointer to nsString is perfectly fine. The data looks fine! */ [nsString drawAtPoint:CGPointMake(0, 0) withFont:clFont]; UIGraphicsPopContext(); CGContextRestoreGState(myContext); } It will happen with other non-unicode supporting methods as well such as CGContextShowTextAtPoint(); the callstack is similar with that as well. Is this any kind of known issue with the iPhone? Or, perhaps, can something outside of this cause be causing an exception in this particular call (drawAtPoint)?

  • General advice and guidelines on how to properly override object.GetHashCode()

    - by Svish
    According to MSDN, a hash function must have the following properties: If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare as equal, the GetHashCode methods for the two object do not have to return different values. The GetHashCode method for an object must consistently return the same hash code as long as there is no modification to the object state that determines the return value of the object's Equals method. Note that this is true only for the current execution of an application, and that a different hash code can be returned if the application is run again. For the best performance, a hash function must generate a random distribution for all input. I keep finding myself in the following scenario: I have created a class, implemented IEquatable<T> and overridden object.Equals(object). MSDN states that: Types that override Equals must also override GetHashCode ; otherwise, Hashtable might not work correctly. And then it usually stops up a bit for me. Because, how do you properly override object.GetHashCode()? Never really know where to start, and it seems to be a lot of pitfalls. Here at StackOverflow, there are quite a few questions related to GetHashCode overriding, but most of them seems to be on quite particular cases and specific issues. So, therefore I would like to get a good compilation here. An overview with general advice and guidelines. What to do, what not to do, common pitfalls, where to start, etc. I would like it to be especially directed at C#, but I would think it will work kind of the same way for other .NET languages as well(?). I think maybe the best way is to create one answer per topic with a quick and short answer first (close to one-liner if at all possible), then maybe some more information and end with related questions, discussions, blog posts, etc., if there are any. I can then create one post as the accepted answer (to get it on top) with just a "table of contents". Try to keep it short and concise. And don't just link to other questions and blog posts. Try to take the essence of them and then rather link to source (especially since the source could disappear. Also, please try to edit and improve answers instead of created lots of very similar ones. I am not a very good technical writer, but I will at least try to format answers so they look alike, create the table of contents, etc. I will also try to search up some of the related questions here at SO that answers parts of these and maybe pull out the essence of the ones I can manage. But since I am not very stable on this topic, I will try to stay away for the most part :p

  • C++ visibility of privately inherited typedefs to nested classes

    - by beldaz
    First time on StackOverflow, so please be tolerant. In the following example (apologies for the length) I have tried to isolate some unexpected behaviour I've encountered when using nested classes within a class that privately inherits from another. I've often seen statements to the effect that there is nothing special about a nested class compared to an unnested class, but in this example one can see that a nested class (at least according to GCC 4.4) can see the public typedefs of a class that is privately inherited by the closing class. I appreciate that typdefs are not the same as member data, but I found this behaviour surprising, and I imagine many others would, too. So my question is threefold: Is this standard behaviour? (a decent explanation of why would be very helpful) Can one expect it to work on most modern compilers (i.e., how portable is it)? #include <iostream> class Base { typedef int priv_t; priv_t priv; public: typedef int pub_t; pub_t pub; Base() : priv(0), pub(1) {} }; class PubDerived : public Base { public: // Not allowed since Base::priv is private // void foo() {std::cout << priv << "\n";} class Nested { // Not allowed since Nested has no access to PubDerived member data // void foo() {std::cout << pub << "\n";} // Not allowed since typedef Base::priv_t is private // void bar() {priv_t x=0; std::cout << x << "\n";} }; }; class PrivDerived : private Base { public: // Allowed since Base::pub is public void foo() {std::cout << pub << "\n";} class Nested { public: // Works (gcc 4.4 - see below) void fred() {pub_t x=0; std::cout << x << "\n";} }; }; int main() { // Not allowed since typedef Base::priv_t private // std::cout << PubDerived::priv_t(0) << "\n"; // Allowed since typedef Base::pub_t is inaccessible std::cout << PubDerived::pub_t(0) << "\n"; // Prints 0 // Not allowed since typedef Base::pub_t is inaccessible //std::cout << PrivDerived::pub_t(0) << "\n"; // Works (gcc 4.4) PrivDerived::Nested o; o.fred(); // Prints 0 return 0; }

I'll start off with the favorite model: favorite/models.py from django.db import models from django.contrib.contenttypes.models import ContentType from django.contrib.contenttypes import generic from django.contrib.auth.models import User class Favorite(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() user = models.ForeignKey(User) content_object = generic.GenericForeignKey() class Admin: list_display = ('key', 'id', 'user') class Meta: unique_together = ("content_type", "object_id", "user") Now, that allows me to loop through the favorites (on a user's "favorites" page, for example) and get the associated blog objects via {{ favorite.content_object.title }}. What I want now, and can't figure out, is what I need to do to the blog model to allow me to have some tether to the favorite (so when it is displayed in a list it can be highlighted, for example). Here is the blog model: blog/models.py from django.db import models from django.db.models import permalink from django.template.defaultfilters import slugify from category.models import Category from section.models import Section from favorite.models import Favorite from django.contrib.auth.models import User from django.contrib.contenttypes.models import ContentType from django.contrib.contenttypes import generic class Blog(models.Model): title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=140, editable=False) author = models.ForeignKey(User) homepage = models.URLField() feed = models.URLField() description = models.TextField() page_views = models.IntegerField(null=True, blank=True, default=0 ) created_on = models.DateTimeField(auto_now_add = True) updated_on = models.DateTimeField(auto_now = True) def __unicode__(self): return self.title @models.permalink def get_absolute_url(self): return ('blog.views.show', [str(self.slug)]) def save(self, *args, **kwargs): if not self.slug: slug = slugify(self.title) duplicate_count = Blog.objects.filter(slug__startswith = slug).count() if duplicate_count: slug = slug + str(duplicate_count) self.slug = slug super(Blog, self).save(*args, **kwargs) class Entry(models.Model): blog = models.ForeignKey('Blog') title = models.CharField(max_length=200) slug = models.SlugField(max_length=140, editable=False) description = models.TextField() url = models.URLField(unique=True) image = models.URLField(blank=True, null=True) created_on = models.DateTimeField(auto_now_add = True) def __unicode__(self): return self.title def save(self, *args, **kwargs): if not self.slug: slug = slugify(self.title) duplicate_count = Entry.objects.filter(slug__startswith = slug).count() if duplicate_count: slug = slug + str(duplicate_count) self.slug = slug super(Entry, self).save(*args, **kwargs) class Meta: verbose_name = "Entry" verbose_name_plural = "Entries" Any guidance?

  • T-SQL selecting values that match ISNUMERIC and also are within a specified range. (plus Linq-to-sql

    - by Toby
    I am trying to select rows from a table where one of the (NVARCHAR) columns is within a numeric range. SELECT ID, Value FROM Data WHERE ISNUMERIC(Value) = 1 AND CONVERT(FLOAT, Value) < 66.6 Unfortunately as part of the SQL spec the AND clauses don't have to short circuit (and don't on MSSQL Server EE 2008). More info: http://stackoverflow.com/questions/789231/is-the-sql-where-clause-short-circuit-evaluated My next attempt was to try this to see if I could achieve delayed evaluation of the CONVERT SELECT ID, Value FROM Data WHERE (CASE WHEN ISNUMERIC(Value) = 1 THEN CONVERT(FLOAT, Value) < 66.6 ELSE 0 END) but I cannot seem to use a < (or any comparison) with the result of a CONVERT. It fails with the error Incorrect syntax near '<'. I can get away with SELECT ID, CONVERT(FLOAT, Value) AS Value FROM Data WHERE ISNUMERIC(Value) = 1 So the obvious solution is to wrap the whole select statement in another SELECT and WHERE and return the converted values from the inner select and filter in there where of the outer select. Unfortunately this is where my Linq-to-sql problem comes in. I am filtering not only by one range but potentialy by many, or just by the existance of the record (there are some date range selects and comparisons I've left out.) Essentially I would like to be able to generate something like this: SELECT ID, TypeID, Value FROM Data WHERE (TypeID = 4 AND ISNUMERIC(Value) AND CONVERT(Float, Value) < 66.6) OR (TypeID = 8 AND ISNUMERIC(Value) AND CONVERT(Float, Value) > 99) OR (TypeID = 9) (With some other clauses in each of those where options.) This clearly doesn't work if I filter out the non-ISNUMERIC values in an inner select. As I mentioned I am using Linq-to-sql (and PredicateBulider) to build up these queries but unfortunately Datas.Where(x => ISNUMERIC(x.Value) ? Convert.ToDouble(x.Value) < 66.6 : false) Gets converted to this which fails the initial problem. WHERE (ISNUMERIC([t0].[Value]) = 1) AND ((CONVERT(Float,[t0].[Value])) < @p0) My last resort will have to be to outer join against a double select on the same table for each of the comparisons but this isn't really an idea solution. I was wondering if anyone has run into similar issues before?

  • CruiseControl.Net Publisher email failing to send e-mail

    - by CrimsonX
    So here's my problem: I cannot seem to be able to configure CruiseControl.NET to send out an e-mail to me when a build occurs. I copied the example from the documentation and filled it in with my own values. http://confluence.public.thoughtworks.org/display/CCNET/Email+Publisher Here's the relevant section of ccnet.config below <publishers> <merge> <files> <file>C:\Build\Temp\*.xml</file> </files> </merge> <xmllogger logDir="buildlogs" /> <statistics> <statisticList> <statistic /> </statisticList> </statistics> <email includeDetails="TRUE" mailhostUsername="user" mailhostPassword="password" useSSL="TRUE"> <from>[email protected]</from> <mailhost>mail.mycompanysmtpserver.com</mailhost> <users> <user name="MyName Lastname" group="buildmaster" address="[email protected]" /> </users> <groups> <group name="buildmaster"> <notifications> <notificationType>Always</notificationType> </notifications> </group> </groups> <modifierNotificationTypes> <NotificationType>Failed</NotificationType> <NotificationType>Fixed</NotificationType> </modifierNotificationTypes> <subjectSettings> <subject buildResult="StillBroken" value="Build is still broken for {CCNetProject}" /> </subjectSettings> </email> </publishers> I have had a successful CruiseControl.NET server configured for some time, and it successfully updates people through CCTray, but I need to add e-mail support as well. I've already looked at the relevant StackOverflow articles like this one and many more and tried my hand at googling the solution but I dont know what I could be doing wrong. The only other thing that I'd like to validate is that I can send/receive e-mails using my username/password with the SMTP server I received from IT (my mail works properly) but I just followed the steps on testing an SMTP server here and everything looks fine http://support.microsoft.com/kb/153119 Anyone have any ideas as to why I'm getting this problem, or how to troubleshoot it further?
