  • Prevent DTD download when parsing XML, redux

    - by harpo
    I have a folder full of XHTML files, and a console program to process them. The problem is, it doesn't work when I'm offline, because The remote name could not be resolved: 'www.w3.org' A number of sites, including this one, say to set the XmlResolver to null. That is not not working. I have tried setting the XmlResolver to null every way that I can think of: in the XmlDocument, in XmlTextReader, and in the XmlReaderSettings. I believe that it's just creating a default instance. I have also tried implementing my own XmlResolver, but I don't know what to return for external items. public class NonXmlResolver : XmlUrlResolver { public override object GetEntity( Uri absoluteUri, string role, Type ofObjectToReturn ) { if ( absoluteUri.Scheme == "http" ) throw new Exception("What you talking 'bout, Willis?"); else return base.GetEntity( absoluteUri, role, ofObjectToReturn ); } } The documents do not use any special entities, only pure XML. This is possible, right?

  • In Oracle 10g, how do I see tables in schemes other than system

    - by Yasir Arsanukaev
    In the hr schema there's a table emloyees, I can query data from it specifying it implicitly SELECT count(*) FROM hr.employees while logged in as system, but when I navigate to Home-Object Browser in the browser I can't see the table employees and other tables in other schemas. Can I manage tables in schemas other than system while logged in as system? Maybe there's some setting which enables me to group tables by schema. My Oracle Database version is 10.2.0.1 Express Edition. IIRC I could see all tables in Oracle Database 10.1.x.y. Thanks.

  • Modifying NSDate to represent 1 month from today

    - by bmalicoat
    I'm adding repeating events to a Cocoa app I'm working on. I have repeat every day and week fine because I can define these mathematically (3600*24*7 = 1 week). I use the following code to modify the date: [NSDate dateWithTimeIntervalSinceNow:(3600*24*7*(weeks))] I know how many months have passed since the event was repeated but I can't figure out how to make an NSDate object that represents 1 month/3 months/6 months/9 months into the future. Ideally I want the user to say repeat monthly starting Oct. 14 and it will repeat the 14th of every month.

  • Objects in interface

    - by Peter Kowalchuk
    I created my own object, PKSurvey. In the interface of the View Controller I can define a pointer to it, then in a method I can alloc it and have an instance. How do I keep the instance beyond the method where it was allocated? I assign values in one method and want to be able to use those values in other methods. Should I allocate it in the viewDidLoad method or should I do it somewhere else? @interface DIrectionalDrillerViewController : UIViewController { PKSurvey *Survey=[PKSurvey new]; ---------------- - (void)viewDidLoad { [Survey new];

  • Chrome Extension contenteditable get and set caret position

    - by jwize
    I am creating an extension where I need to insert a link into the gmail window. I am able to create a simple extension button in the top of the window and execute code that does replaces all the links. Now, I want to do add links in the contenteditable section as I type. It seems like there should be a simple way to replace text with a link in the document object model. If this is not true I need to do three things. Insert text from the current caret position Capture the caret position. Set the caret position by its offset. I have tried using window.getSelection within the gmail context(that is a body element that is set to contenteditable and embedded inside an iframe in the gmail tab) to get the current range and position. The selection is always empty and contains no ranges regardless of whether text is selected or not.

  • Help! How to get the event handler with IE Dom interfaces?

    - by usfree74
    Hey Gurus, I am working to use IE Dom interface to automate IE page access. I am trying to get all event handlers defined in a page. I am using IHTMLElement object now for this purpose. If the html page defines "onclick=xxx", element.onclick returns the click handler. However, if an event handler is defined in javascript, element.onclick simply returns NULL. What's the right way to get the event handler then? Thanks, xin Below is an example that uses javascript to define event handler. $(document).ready(function(){ $("a").click(function(event){ $(this).hide("slow"); alert("Thanks for visiting!"); window.location="http://cnn.com"; }); }); jQuery

  • Can't Instantiate Windsor Custom Component Activator

    - by jeffn825
    Hi, I'm getting an exception calling Resolve: KernelException: Could not instantiate custom activator Inner Exception: {"Constructor on type 'MyProj.MyAdapter`1[[MyProj.MyBusinessObject, MyAsm, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' not found."} There's definitely a public parameterless constructor there (and I've verified this using reflection at runtime)...so I figure the problem might have to do with the fact that it's generic? I've tried getting the component model object and setting RequiresGenericArguments to true, but that hasn't gotten me anywhere. Any help would be much appreciated! Thanks.

  • Why is the CoreData stack in XCode's CoreData enabled template treated as private?

    - by rob5408
    In regards to XCode templates with CoreData enabled, I've read http://stackoverflow.com/questions/2729055/unclear-use-of-property-in-window-app-using-core-data which goes over the 'what' in the templates. But I am having an issue with the 'why'. By declaring the category in the implementation file, the CoreData accessors act like private methods. The problem with that is whenever you want to use CoreData elsewhere in your app, you need some extra code. I've figured you need to either supply your own method that exposes the managed object context, such as... - (NSManagedObjectContext *)getManagedObjectContext { return self.managedObjectContext; } ...which will allow other parts of your app to use it. Or you would need to jam pack your app delegate with specific methods to return managed objects, ie getProducts or setUser. Can anyone shed light on the reasoning here?

  • [C#] Async threaded tcp server

    - by mark_dj
    I want to create a high performance server in C# which could take about ~10k clients. Now i started writing a TcpServer with C# and for each client-connection i open a new thread. I also use one thread to accept the connections. So far so good, works fine. The server has to deserialize AMF incoming objects do some logic ( like saving the position of a player ) and send some object back ( serializing objects ). I am not worried about the serializing/deserializing part atm. My main concern is that I will have a lot of threads with 10k clients and i've read somewhere that an OS can only hold like a few hunderd threads. Are there any sources/articles available on writing a decent async threaded server ? Are there other possibilties or will 10k threads work fine ? I've looked on google, but i couldn't find much info about design patterns or ways which explain it clearly

  • DoFactory Architecture Design

    - by Brendan Vogt
    Hi, Has anybody used the Patterns in Action from the Do Factory? I just have a question on the architecture. I always thought that the service must call the repository. In the solution the have ActionService and a repository. Lets say I want to get all the customers then in my controller I would call the repository's GetCustomers method. This will then call ActionService's GetCustomer's method. And then lastly another GetCustomers method is called in the customer data access object. Is this right? Any comments on the way that they implemented things in the Patterns in Action?

  • [Java] Force an unchecked call

    - by François Cassistat
    Hello, Sometimes, when using Java reflection or some special storing operation into Object, you end up with unchecked warnings. I got used to it and when I can't do anything about it, I document why one call is unchecked and why it should be considered as safe. But, for the first time, I've got an error about a unchecked call. This function : public <K,V extends SomeClass & SomeOtherClass<K>> void doSomethingWithSomeMap (Map map, V data); I thought that calling it this way : Map someMap = ...; SomeClass someData = ...; doSomethingWithSomeMap(someMap, someData); would give me an unchecked call warning. Jikes does a warning, but javac gives me an error : Error: <K,V>doSomethingWithSomeMap(java.util.Map<K,V>,V) in SomeClass cannot be applied to (java.util.Map,SomeClass) Any way to force it to compile with a warning? Thanks.

  • How can I separate Logic/UI in Android

    - by Ungureanu Liviu
    Hi, I want as my application to be structured in 2 parts: the logic code and the UI. I've tried to implement that using a controller class(here I keep the logic code) inside of each activity. The activity send messages to controller and receive the answer in two ways: the answer is returned immediately (if the action is not complex and it can be done in a verry short time) the activity set some listeners and the controller fire this listener when the action is complete. The problems appears when the controller have a lot of objects(each object should handle a set of actions and for each action I have to set & trigger a listener): it is hard to keep the code syncronized. I'm asking if you know a better way to implement this mechanism. Thank you.

  • XmlDocument caching memory usage

    - by mdsharpe
    We are seeing very high memory usage in .NET web applications which use XmlDocument. A small (~5MB) XML document is loaded into an XmlDocument object and stored in HttpContext.Cache for easy querying and XSLT transformation on each page load. The XML is modified on disk periodically so a cache has a dependency on the file. Such an application appears to be using hundreds of megabytes of RAM. I have experimented with requesting garbage collection on each request start, and this keeps the RAM usage far lower but I cannot imagine this is good practise. Does anyone have any suggestions as to how we can achieve the same goal but with lower RAM usage?

  • "Collection was modified; enumeration operation may not execute." on form disposal.

    - by cyclotis04
    "Collection was modified; enumeration operation may not execute." appears to be a common error with foreach loops, but I can't figure mine out. I have two classes of forms. One is begun on startup, and a button creates new instances of the second form, and displays them. When I close the secondary forms, I get an InvalidOperationException. FirstForm.cs public partial class FirstForm : Form { SecondForm frmSecond; ... private void button1_Click(object sender, EventArgs e) { frmSecond= new SecondForm (); frmSecond.Show(); } } SecondForm.designer.cs partial class SecondForm { ... protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); // InvalidOperationException thrown here. } }

  • python iterators and thread-safety

    - by Igor
    I have a class which is being operated on by two functions. One function creates a list of widgets and writes it into the class: def updateWidgets(self): widgets = self.generateWidgetList() self.widgets = widgets the other function deals with the widgets in some way: def workOnWidgets(self): for widget in self.widgets: self.workOnWidget(widget) each of these functions runs in it's own thread. the question is, what happens if the updateWidgets() thread executes while the workOnWidgets() thread is running? I am assuming that the iterator created as part of the for...in loop will keep some kind of reference to the old self.widgets object? So I will finish iterating over the old list... but I'd love to know for sure.

  • Does all SPWeb or SPSite instances automatically disposed when console app process has ended?

    - by Janis Veinbergs
    We have Best practices on using disposable object in SharePoint. But i`m thinking - can I skip these when using Console Application? That's some code I want to execute once and after that process has finished. Do or don't SPSite and SPWeb's remain opened somwhere? Why i`m asking this? I just don't want to stress when using something like var lists = from web in site.AllWebs.Cast<SPWeb>() where web is meeting workspace && list is task list select list then do some stuff on lists etc. Some serious resource leak there because webs get opened, filtered and NOT closed. So should I worry in console app?

  • What's all the hype over objectsets in Entity Framework 4?

    - by Kohan
    I am an intermediate user of EF in .net 3.5 and have recently moved to working with .net 4. One thing i keep coming across when reading various tutorials is the use of ObjectSets instead of ObjectQuerys and that they are a great new feature. What is so great about them? Reading this MSDN article titled "Working with ObjectSet (Entity Framework)" It shows two examples on how to add a Product.. one for 3.5 and another for 4.0. http://msdn.microsoft.com/en-us/library/ee473442.aspx Through my lack of knowledge I am possibly bringing up a seperate point here, but i never added a Product like this: //In .NET Framework 3.5 SP1, use the following code: using (AdventureWorksEntities context = new AdventureWorksEntities()) { // Add the new object to the context. context.AddObject("Products", newProduct); } I would have just used context.AddToProducts(newProduct); Please enlighten me. Kind regards, Kohan

  • Parsing files with python

    - by iHeartDucks
    My input file is going to be something like this key "value" key "value" ... the above lines repeat What I do is read the file contents, populate an object with the data and return it. There are only a set number of keys that can be present in the file. Since I am a beginner in python, I feel that my code to read the file is not that good My code is something like this ObjInstance = CustomClass() fields = ['key1', 'key2', 'key3'] for field in fields: for line in f: if line.find(field) >= 0: if pgn_field == 'key1': objInstance.DataOne = get_value_using_re(line) elif pgn_field == 'key2': objInstance.DataTwo = get_value_using_re(line) return objInstance; The function "get_value_using_re" is very simple, it looks for a string in between the double quotes and returns it. I fear that I will have multiple if elif statements and I don't know if this is the right way or not. Am I doing the right thing here?

  • E.cancel loop in Visual basic

    - by Ahmed
    I am making an server control application ( simple with some buttons to start/stop the server ) And when the user wants to close the application there will be prompted an confirm box. Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing Dim response As Integer response = MsgBox("Are you sure you want to stop the server", vbYesNo, "Stop Server ?") If response = vbYes Then Shell("cscript ""stop.vbs""", 1) Close() Else e.Cancel = True End If End Sub That is the code I have now. But when I start the application and close it with the X button or with "Close Window" I will be prompted with the question until I click on no, then it will close. It's a loop and it stops when you first click on yes then on no. Can someone help me with solving this ?

  • Code equivalence between Javascript and PHP

    - by xdevel2000
    I'm trying to learn PHP and I wish to know if there are some function equivalence constructs: In JS I can do: var t = function() {}; t(); myObj.DoStuff = function() {} // here I add a method at run-time myObj.DoStuff(); myObj["DoStuff"](); var j = myObj.DoStuff; j(); and so other things with function evaluation. In Js objects are associative arrays so every properties is accessible with the subscript notation... Can I add a method at run-time to a class template so next its object instances can have it? In JS I can do that via a prototype function property.

  • JFrame the same shape as an Image / Program running in background

    - by Jan Weber
    My question is simple, the solution surely not. I am looking for a way to shape a JFrame the same as an Image it will be displaying. By shape I mean the shape of the pixels that have an alpha != 0. I've already found a working example using a GeneralPath object, but it created ~110000 "nodes" for an Image of about 500*400, so starting the JFrame took more than 2 minutes, which is definitely not the desired effect, the startup should be in under 2 seconds. Thanks for your time.
