• How can I use STL sort in c++ to sort some values in the class?

  - by Morteza M.

  I have a class named Graph, in this class I have a member named V, it is a vector. I have a struct named Edge, and a list of Edges. like below: struct Edge{ int u; int v; Edge(int u,int v){ this-u=u; this-v=v; } }; class Graph{ vector < Vertex > V; . . . int edgeCmp(Edge* x,Edge* y){ return (V[x-v].dv].d)?1:0; } void someFunction(){ list backEdges; backEdges.sort(&Graph::edgeCmp); } } But it doesn't work!! may someone help me to do such a thing?

• Forced naming of parameters in python

  - by Mark Mayo

  In python you may have a function definition: def info(object, spacing=10, collapse=1) which could be called in any of the following ways: info(odbchelper) info(odbchelper, 12) info(odbchelper, collapse=0) info(spacing=15, object=odbchelper) thanks to python's allowing of any-order arguments, so long as they're named. The problem we're having is as some of our larger functions grow, people might be adding parameters between spacing and collapse, meaning that the wrong values may be going to parameters that aren't named. In addition sometimes it's not always clear as to what needs to go in. We're after a way to force people to name certain parameters - not just a coding standard, but ideally a flag or pydev plugin? so that in the above 4 examples, only the last would pass the check as all the parameters are named. Odds are we'll only turn it on for certain functions, but any suggestions as to how to implement this - or if it's even possible would be appreciated.

• How to synchronize two DataBase Schemas Oracle 10G?

  - by gnash-85

  Hi Masters, Good Day, I am new and very naive to Oracle DB. I am using Oracle 10G. Let me explain to you. I have one source database named ( DB1) and Target Database named (DB2). I have 2 schema's named dbs1 and dbs2 in the source database (DB1). I have exported both the database schemas in Source Database (DB1) and imported it successfully into the Target Database (DB2). Now I face a challenge in synchronizing these database schemas every time from Source DB (DB1) to Target DB (DB2). Can anyone please help in letting me know how can achieve this synchronization? It would a great help. Thanks Nash

• Inner join 2 tables one to many 2 where clauses

  - by user2892350

  I'm a relative rookie at this,so please bear with me... I have 2 tables: OrderDetail and OrderMaster...both have a column named SalesOrder. OrderDetail table has multiple rows per unique SalesOrder. OrderMaster table has one row per unique SalesOrder. OrderDetail has a column named LineType. OrderMaster has a column named OrderStatus. I want to select all records from OrderDetail that have a LineType of "1" AND whose matching SalesOrder line in the OrderMaster table has a OrderStatus column value of "4". In plain English, orders with a Status 4 are open and ready to ship, LineType value of 1 means the Detail Line is a product code. How should this query be structured? It's going into VS 2008 (VB). Many thanks in advance!!! Mike

• Java: How to get Unicode name of a character (or its type category)?

  - by java.is.for.desktop

  Hello, everyone! The Character class in Java defines methods which check a given char argument for equality with certain Unicode chars or for belonging to some type category. These chars and type categories are named. As stated in given javadoc, examples for named chars are HORIZONTAL TABULATION, FORM FEED, ...; example for named type categories are SPACE_SEPARATOR, PARAGRAPH_SEPARATOR, ... However, being byte or int values instead of enums, the name of these types are "hidden" at runtime. So, is there a possibility to get characters' and/or type categories' names at runtime?

• Dynamically generated controls issue.

  - by Thomas

  I have a form with a panel docked in it. I then dynamically create 15 panels (named: panel_n) and 15 pictureboxes (named: picturebox_n) on the primary panel (named ContainerPanel). When dragging the any picturebox over a panel (panel_n) created using the relevant mouse events. I would like to get the panel's name that the picture box was dragged over. The mouse cursor seems to be captured. I have tried creating a IMessageFilter interface, but there are still no events that trigger when dragging one of the pictureboxes over any one of the panels. The ClientRectangle.IntersectsWith function also does not work as the co-ords are always 0,0. All I need is the panel name where the picturebox was dragged over (preferably on the mouseup event)

• What is the purpose of netcat's "-w timeout" option when ssh tunneling?

  - by jrdioko

  I am in the exact same situation as the person who posted another question, I am trying to tunnel ssh connections through a gateway server instead of having to ssh into the gateway and manually ssh again to the destination server from there. I am trying to set up the solution given in the accepted answer there, a ~/.ssh/config that includes: host foo User webby ProxyCommand ssh a nc -w 3 %h %p host a User johndoe However, when I try to ssh foo, my connection stays alive for 3 seconds and then dies with a Write failed: Broken pipe error. Removing the -w 3 option solves the problem. What is the purpose of that -w 3 in the original solution, and why is it causing a Broken pipe error when I use it? What is the harm in omitting it?

• Limit on WMIC requests from a Windows Service

  - by Anders

  Hi all, Does anyone know if there is limit on how many wmic requests Windows can handle simultaneously if they are originating from a Windows service? The reason I'm asking is because my application fails when too many simultaneous requests have been initiated. I don't get any data back from the application. However, If I compile the Python application and run it as a stand alone application all will work fine. The wmic calls are looking like this: subprocess.Popen("wmic path Win32_PerfFormattedData_PerfOS_Memory get CommittedBytes", stdout=subprocess.PIPE, stderr=subprocess.PIPE) This makes me wonder, is there a limit Windows Services and what they can perform? I mean, if the .exe file can handle all requests, then it must be something to do with the fact that I have compiled it as a Windows service.

• Process ANSI escape codes before piping

  - by Tiddo

  I'm trying to pipe the output of a script (Mocha) to another script. However there is one problem: Mocha generates quite a few ansi escape characters to update the screen on the fly. These characters are also send through the pipe. Is there a way to process the ansi sequence such that the output is the same as the final output to the screen? I do want to keep color escape sequences, but not the curser movement escapes. Edit: I have a partial solution now (for Mocha only): so far it seems that Mocha with the spec output (the one I use) only generates color ecape characters and the CSI 0G escape sequence. The CSI 0G escape character means that the cursor should move back to the beginning of the line. Mocha uses this to overwrite a line completely. Therefore you could simply create a sed regexp which will delete everything up to that escape sequence on a line: sed 's/^.*\x1b\[0G//g'. I am still looking for the complete solution though.

• Help debugging Sendmail/Mailman configuration issue

  - by inxilpro

  Hi folks, I'm trying to configure a server with Sendmail and Mailman. I've been getting "Broken pipe" errors for a while, and have slowly been debugging. I fixed some permission issues, and changed the user that Mailman expects to be called from, among other things. Finally, I'd gone through everything I could think of, so I added a new test to see if it's the Mailman script or Sendmail that's causing the problem. Here's the error I'm getting now (stripped of timestamps and identifying information): <-- MAIL FROM:[email protected] Authentication-Warning: xxxxx.org: xxxxxxxxxxxxxx.net [xx.xx.xxx.xxx] didn't use HELO protocol --- 250 2.1.0 [email protected]...

• Parse java console output with awk

  - by Bob Rivers

  Hi, I'm trying to use awk to parse an output generated by a java application, but it isn't working. It seems that the command after the pipe isn't able to get/see the data throwed by the java app. I'm executing the following command (with the return generated by the command): [root@localhost]# java -jar jmxclient.jar usr:pass host:port java.lang:type=Threading ThreadCount 06/11/2010 15:46:37 -0300 org.archive.jmx.Client ThreadCount: 103 What I need it's only the last part of the string. So I'm tryng to use awk (with pipe at the end of the line |awk -F ':' '{print $4}': [root@localhost]# java -jar jmxclient.jar usr:pass host:port java.lang:type=Threading ThreadCount|awk -F ':' '{print $4}' But the output isn't being parsed. It throws the entire string: 06/11/2010 15:46:37 -0300 org.archive.jmx.Client ThreadCount: 103 I also tryed to use |cut -f4 -d":" with the same result: the string isn't parsed. So my question is, how do I parse the output in order to get just the number at the end of the string? TIA, Bob

• kSOAP2 and SOAPAction on Android

  - by Matze

  Hi everyone, I am trying to access a Webservice with kSOAP2 on an Android Phone. I think the connection is being established, but the server won't answer my request since I'm not providing a SOAP Action Header which seems to be required in SOAP Version 1.1(please correct me if I'm wrong here) which I have to use since the server does not support Version 1.2 . The concrete Faultcode which is returning in the request looks like this: faultactor null faultcode "S:Server" (id=830064966432) faultstring "String index out of range: -11" (id=830064966736) The errorcode which is generated on the server (I'm running it on a localhost) looks like this: 4.05.2010 20:20:29 com.sun.xml.internal.ws.transport.http.HttpAdapter fixQuotesAroundSoapAction WARNUNG: Received WS-I BP non-conformant Unquoted SoapAction HTTP header: http://server.contextlayer.bscwi.de/createContext 24.05.2010 20:20:29 com.sun.xml.internal.ws.server.sei.EndpointMethodHandler invoke SCHWERWIEGEND: String index out of range: -11 java.lang.StringIndexOutOfBoundsException: String index out of range: -11 at java.lang.String.substring(Unknown Source) at de.bscwi.contextlayer.xml.XmlValidator.isValid(XmlValidator.java:41) at de.bscwi.contextlayer.server.ContextWS.createContext(ContextWS.java:45) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.sun.xml.internal.ws.api.server.InstanceResolver$1.invoke(Unknown Source) at com.sun.xml.internal.ws.server.InvokerTube$2.invoke(Unknown Source) at com.sun.xml.internal.ws.server.sei.EndpointMethodHandler.invoke(Unknown Source) at com.sun.xml.internal.ws.server.sei.SEIInvokerTube.processRequest(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.__doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber._doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.runSync(Unknown Source) at com.sun.xml.internal.ws.server.WSEndpointImpl$2.process(Unknown Source) at com.sun.xml.internal.ws.transport.http.HttpAdapter$HttpToolkit.handle(Unknown Source) at com.sun.xml.internal.ws.transport.http.HttpAdapter.handle(Unknown Source) at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handleExchange(Unknown Source) at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handle(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.AuthFilter.doFilter(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.ServerImpl$Exchange$LinkHandler.handle(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.ServerImpl$Exchange.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) The relevant part of the WSDL (at least that's what I'm thinking) looks like this: <operation name="createContext"> <soap:operation soapAction=""/> - <input> <soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> </input> - <output> <soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> </output> </operation> In my code I'm adding a Header, but it seems like I'm doing it wrong: private static final String SOAP_ACTION = ""; //...

• In the Aggregate: How Will We Maintain Legacy Systems?

  - by Jim G.

  NEW YORK - With a blast that made skyscrapers tremble, an 83-year-old steam pipe sent a powerful message that the miles of tubes, wires and iron beneath New York and other U.S. cities are getting older and could become dangerously unstable. July 2007 Story About a Burst Steam Pipe in Manhattan We've heard about software rot and technical debt. And we've heard from the likes of: "Uncle Bob" Martin - Who warned us about "the consequences of making a mess". Michael C. Feathers - Who gave us guidance for 'Working Effectively With Legacy Code'. So certainly the software engineering community is aware of these issues. But I feel like our aggregate society does not appreciate how these issues can plague working systems and applications. As Steve McConnell notes: ...Unlike financial debt, technical debt is much less visible, and so people have an easier time ignoring it. If this is true, and I believe that it is, then I fear that governments and businesses may defer regular maintenance and fortification against hackers until it is too late. [Much like NYC and the steam pipes.] My Question: Do you share my concern? And if so, is there a way that we can avoid the software equivalent of NYC and the steam pipes?

• ClickOnce manifest problem

  - by TWith2Sugars

  We are currently deploying a WPF 4 app via click once and there is a scenario when the installation fails. If the user does not have .Net 4.0 Full install and attempts to install our app the framework installs fine but the app fails to install. If we re-run the installation again the app installs fine.

• Use ASP.NET 4 Browser Definitions with ASP.NET 3.5

  - by Stephen Walther

  We updated the browser definitions files included with ASP.NET 4 to include information on recent browsers and devices such as Google Chrome and the iPhone. You can use these browser definition files with earlier versions of ASP.NET such as ASP.NET 3.5. The updated browser definition files, and instructions for installing them, can be found here: http://aspnet.codeplex.com/releases/view/41420 The changes in the browser definition files can cause backwards compatibility issues when you upgrade an ASP.NET 3.5 web application to ASP.NET 4. If you encounter compatibility issues, you can install the old browser definition files in your ASP.NET 4 application. The old browser definition files are included in the download file referenced above. What’s New in the ASP.NET 4 Browser Definition Files The complete set of browsers supported by the new ASP.NET 4 browser definition files is represented by the following figure:     If you look carefully at the figure, you’ll notice that we added browser definitions for several types of recent browsers such as Internet Explorer 8, Firefox 3.5, Google Chrome, Opera 10, and Safari 4. Furthermore, notice that we now include browser definitions for several of the most popular mobile devices: BlackBerry, IPhone, IPod, and Windows Mobile (IEMobile). The mobile devices appear in the figure with a purple background color. To improve performance, we removed a whole lot of outdated browser definitions for old cell phones and mobile devices. We also cleaned up the information contained in the browser files. Here are some of the browser features that you can detect: Are you a mobile device? <%=Request.Browser.IsMobileDevice %> Are you an IPhone? <%=Request.Browser.MobileDeviceModel == "IPhone" %> What version of JavaScript do you support? <%=Request.Browser["javascriptversion"] %> What layout engine do you use? <%=Request.Browser["layoutEngine"] %>   Here’s what you would get if you displayed the value of these properties using Internet Explorer 8: Here’s what you get when you use Google Chrome: Testing Browser Settings When working with browser definition files, it is useful to have some way to test the capability information returned when you request a page with different browsers. You can use the following method to return the HttpBrowserCapabilities the corresponds to a particular user agent string and set of browser headers: public HttpBrowserCapabilities GetBrowserCapabilities(string userAgent, NameValueCollection headers) { HttpBrowserCapabilities browserCaps = new HttpBrowserCapabilities(); Hashtable hashtable = new Hashtable(180, StringComparer.OrdinalIgnoreCase); hashtable[string.Empty] = userAgent; // The actual method uses client target browserCaps.Capabilities = hashtable; var capsFactory = new System.Web.Configuration.BrowserCapabilitiesFactory(); capsFactory.ConfigureBrowserCapabilities(headers, browserCaps); capsFactory.ConfigureCustomCapabilities(headers, browserCaps); return browserCaps; } At the end of this blog entry, there is a link to download a simple Visual Studio 2008 project – named Browser Definition Test -- that uses this method to display capability information for arbitrary user agent strings. For example, if you enter the user agent string for an iPhone then you get the results in the following figure: The Browser Definition Test application enables you to submit a user-agent string and display a table of browser capabilities information. The browser definition files contain sample user-agent strings for each browser definition. I got the iPhone user-agent string from the comments in the iphone.browser file. Enumerating Browser Definitions Someone asked in the comments whether or not there is a way to enumerate all of the browser definitions. You can do this if you ware willing to use a little reflection and read a private property. The browser definition files in the config\browsers folder get parsed into a class named BrowserCapabilitesFactory. After you run the aspnet_regbrowsers tool, you can see the source for this class in the config\browser folder by opening a file named BrowserCapsFactory.cs. The BrowserCapabilitiesFactoryBase class has a protected property named BrowserElements that represents a Hashtable of all of the browser definitions. Here's how you can read this protected property and display the ID for all of the browser definitions: var propInfo = typeof(BrowserCapabilitiesFactory).GetProperty("BrowserElements", BindingFlags.NonPublic | BindingFlags.Instance); Hashtable browserDefinitions = (Hashtable)propInfo.GetValue(new BrowserCapabilitiesFactory(), null); foreach (var key in browserDefinitions.Keys) { Response.Write("" + key); } If you run this code using Visual Studio 2008 then you get the following results: You get a huge number of outdated browsers and devices. In all, 449 browser definitions are listed. If you run this code using Visual Studio 2010 then you get the following results: In the case of Visual Studio 2010, all the old browsers and devices have been removed and you get only 19 browser definitions. Conclusion The updated browser definition files included in ASP.NET 4 provide more accurate information for recent browsers and devices. If you would like to test the new browser definitions with different user-agent strings then I recommend that you download the Browser Definition Test project: Browser Definition Test Project

• WCF security via message headers

  - by exalted

  I'm trying to implement "some sort of" server-client & zero-config security for some WCF service. The best (as well as easiest to me) solution that I found on www is the one described at http://www.dotnetjack.com/post/Automate-passing-valuable-information-in-WCF-headers.aspx (client-side) and http://www.dotnetjack.com/post/Processing-custom-WCF-header-values-at-server-side.aspx (corrisponding server-side). Below is my implementation for RequestAuth (descibed in the first link above): using System; using System.Diagnostics; using System.ServiceModel; using System.ServiceModel.Configuration; using System.ServiceModel.Dispatcher; using System.ServiceModel.Description; using System.ServiceModel.Channels; namespace AuthLibrary { /// <summary> /// Ref: http://www.dotnetjack.com/post/Automate-passing-valuable-information-in-WCF-headers.aspx /// </summary> public class RequestAuth : BehaviorExtensionElement, IClientMessageInspector, IEndpointBehavior { [DebuggerBrowsable(DebuggerBrowsableState.Never)] private string headerName = "AuthKey"; [DebuggerBrowsable(DebuggerBrowsableState.Never)] private string headerNamespace = "http://some.url"; public override Type BehaviorType { get { return typeof(RequestAuth); } } protected override object CreateBehavior() { return new RequestAuth(); } #region IClientMessageInspector Members // Keeping in mind that I am SENDING something to the server, // I only need to implement the BeforeSendRequest method public void AfterReceiveReply(ref System.ServiceModel.Channels.Message reply, object correlationState) { throw new NotImplementedException(); } public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel) { MessageHeader<string> header = new MessageHeader<string>(); header.Actor = "Anyone"; header.Content = "TopSecretKey"; //Creating an untyped header to add to the WCF context MessageHeader unTypedHeader = header.GetUntypedHeader(headerName, headerNamespace); //Add the header to the current request request.Headers.Add(unTypedHeader); return null; } #endregion #region IEndpointBehavior Members public void AddBindingParameters(ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters) { throw new NotImplementedException(); } public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime) { clientRuntime.MessageInspectors.Add(this); } public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher) { throw new NotImplementedException(); } public void Validate(ServiceEndpoint endpoint) { throw new NotImplementedException(); } #endregion } } So first I put this code in my client WinForms application, but then I had problems signing it, because I had to sign also all third-party references eventhough http://msdn.microsoft.com/en-us/library/h4fa028b(v=VS.80).aspx at section "What Should Not Be Strong-Named" states: In general, you should avoid strong-naming application EXE assemblies. A strongly named application or component cannot reference a weak-named component, so strong-naming an EXE prevents the EXE from referencing weak-named DLLs that are deployed with the application. For this reason, the Visual Studio project system does not strong-name application EXEs. Instead, it strong-names the Application manifest, which internally points to the weak-named application EXE. I expected VS to avoid this problem, but I had no luck there, it complained about all the unsigned references, so I created a separate "WCF Service Library" project inside my solution containing only code above and signed that one. At this point entire solution compiled just okay. And here's my problem: When I fired up "WCF Service Configuration Editor" I was able to add new behavior element extension (say "AuthExtension"), but then when I tried to add that extension to my end point behavior it gives me: Exception has been thrown by the target of an invocation. So I'm stuck here. Any ideas?
