  • JList strike through

    - by kap
    I have a list of data in a JList component in my GUI. I would like to know if there is a method that i can call on the list element(s) to strike through a particular element in the list. I would like to draw a line through the element to appear as if that element is canceled. I want a similar thing like the strike through functionality in Microsoft Word document whereby a line i drawn through the text. thanks for your help

  • WCF FaultContracts not working for Silverlight Client Proxy

    - by sarwara
    We have a Silverlight application client and a WCF Service hosted as Managed Window Service and exposing Service Contracts on BasicHttpBinding. We are sending FaultContract on the wire in case of exception is caught with the WCF Service Code. We are facing following problem as: A. If we have Synconized proxy call (in case of Window or Web Client), we are able to catch the Fault Contract. B. If we are using Silverlight Client which uses Asyncronized calls, we are unable to catch the Fault Contract. We need help on later problem (B.), Thanks in advance

  • How can I read a file's contents directly with Perl's Net::FTP?

    - by muruga
    I want to get the file from one host to another host. We can get the file using the NET::FTP module. In that module we can use the get method to get the file. But I want the file contents instead of the file. I know that using the read method we can read the file contents. But how do I call the read function and how do I get the file contents?

  • Designing a web service to be called by another language

    - by CollegeProgrammer
    This will sound naive (but then I am a junior programmer), but if I write a web service say in Python (standard WSDL web service), I then need to host it so it is reachable from an end point. This will give a URI for the service and then from another language, say Java or VB.NET (any), I can add a web service (this one) and then call the web service's object model, correct? Thanks

  • overloading new/delete problem

    - by hidayat
    This is my scenario, Im trying to overload new and delete globally. I have written my allocator class in a file called allocator.h. And what I am trying to achieve is that if a file is including this header file, my version of new and delete should be used. So in a header file "allocator.h" i have declared the two functions extern void* operator new(std::size_t size); extern void operator delete(void *p, std::size_t size); I the same header file I have a class that does all the allocator stuff, class SmallObjAllocator { ... }; I want to call this class from the new and delete functions and I would like the class to be static, so I have done this: template<unsigned dummy> struct My_SmallObjectAllocatorImpl { static SmallObjAllocator myAlloc; }; template<unsigned dummy> SmallObjAllocator My_SmallObjectAllocatorImpl<dummy>::myAlloc(DEFAULT_CHUNK_SIZE, MAX_OBJ_SIZE); typedef My_SmallObjectAllocatorImpl<0> My_SmallObjectAllocator; and in the cpp file it looks like this: allocator.cc void* operator new(std::size_t size) { std::cout << "using my new" << std::endl; if(size > MAX_OBJ_SIZE) return malloc(size); else return My_SmallObjectAllocator::myAlloc.allocate(size); } void operator delete(void *p, std::size_t size) { if(size > MAX_OBJ_SIZE) free(p); else My_SmallObjectAllocator::myAlloc.deallocate(p, size); } The problem is when I try to call the constructor for the class SmallObjAllocator which is a static object. For some reason the compiler are calling my overloaded function new when initializing it. So it then tries to use My_SmallObjectAllocator::myAlloc.deallocate(p, size); which is not defined so the program crashes. So why are the compiler calling new when I define a static object? and how can I solve it?

  • Unable to read data from the transport connection: the connection was closed

    - by webdreamer
    The exception is Remoting Exception - Authentication Failure. The detailed message says "Unable to read data from the transport connection: the connection was closed." I'm having trouble with creating two simple servers that can comunicate as remote objects in C#. ServerInfo is just a class I created that holds the IP and Port and can give back the address. It works fine, as I used it before, and I've debugged it. Also the server is starting just fine, no exception is thrown, and the channel is registered without problems. I'm using Forms to do the interfaces, and call some of the methods on the server, but didn't find any problems in passing the parameters from the FormsApplication to the server when debugging. All seems fine in that chapter. public ChordServerProgram() { RemotingServices.Marshal(this, "PADIBook"); nodeInt = 0; } public void startServer() { try { serverChannel = new TcpChannel(serverInfo.Port); ChannelServices.RegisterChannel(serverChannel, true); } catch (Exception e) { Console.WriteLine(e.ToString()); } } I run two instances of this program. Then startNode is called on one of the instances of the application. The port is fine, the address generated is fine as well. As you can see, I'm using the IP for localhost, since this server is just for testing purposes. public void startNode(String portStr) { IPAddress address = IPAddress.Parse("127.0.0.1"); Int32 port = Int32.Parse(portStr); serverInfo = new ServerInfo(address, port); startServer(); //node = new ChordNode(serverInfo,this); } Then, in the other istance, through the interface again, I call another startNode method, giving it a seed server to get information from. This is where it goes wrong. When it calls the method on the seedServer proxy it just got, a RemotingException is thrown, due to an authentication failure. (The parameter I'll want to get is the node, I'm just using the int to make sure the ChordNode class has nothing to do with this error.) public void startNode(String portStr, String seedStr) { IPAddress address = IPAddress.Parse("127.0.0.1"); Int32 port = Int32.Parse(portStr); serverInfo = new ServerInfo(address, port); IPAddress addressSeed = IPAddress.Parse("127.0.0.1"); Int32 portSeed = Int32.Parse(seedStr); ServerInfo seedInfo = new ServerInfo(addressSeed, portSeed); startServer(); ChordServerProgram seedServer = (ChordServerProgram)Activator.GetObject(typeof(ChordServerProgram), seedInfo.GetFullAddress()); // node = new ChordNode(serverInfo,this); int seedNode = seedServer.nodeInt; // node.chordJoin(seedNode.self); }

  • javascript instanceof get type from string name

    - by dcp
    Let's say I have this (assume the name variable is "receiver"): if (!(receiver instanceof com.HTMLReceiver)) { throw new com.IllegalArgumentException( name + " is not an instance of com.HTMLReceiver."); } I'd like to factor this code out into a common method so I could call it like this: Helper.checkInstance(receiver, "com.HTMLReceiver"); But I don't know of a way to convert the com.HTMLReceiver from a string to its actual type so I can use instanceof on it. Is there a way?

Please help me if you have any idea regarding this.

  • domain modeling naming problem

    - by cherouvim
    Hello There are some simple entities in an application (e.g containing only id and title) which rarely change and are being referenced by the more complex entities of the application. These are usually entities such as Country, City, Language etc. How are these called? I've used the following names for those in the past but I'm not sure which is the best way to call them: reference data lookup values dictionaries thanks

  • Removing Directions markers from the Google Maps API V3

    - by anonymous
    To remove a normal marker from a map, I understand you simply call marker.setMap(null), but when implementing the Google Maps directions services, it automatically adds markers A and B onto the map ( calculating directions from point A to point B ). I do not have control over these markers, so I cannot remove them in the normal way. So how can I remove these markers (I have custom markers on the map instead)?
