  • Need help understanding "TypeError: default __new__ takes no parameters" error in python

    - by Gordon Fontenot
    For some reason I am having trouble getting my head around __init__ and __new__. I have a bunch of code that runs fine from the terminal, but when I load it as a plugin for Google Quick Search Box, I get the error TypeError: default __new__ takes no parameters. I have been reading about the error, and it's kind of making my brain spin. As it stands I have 3 classes, with no sub-classes, each class has it's own defs. I never use def __init__ or def __new__, but I have gotten the distinct feeling that these are the functions (or the lack thereof) that would be giving me the error. I have no idea how to summarize the code down to a snippet that would be helpful here, since I'm a bit over my head, but the entire script can be found at github. Not expecting anyone to bugfix my code for me, I am just at my wit's end on this. A simple (plain english, not the quote from the python docs which I have read 20 times and still don't really understand) explination of why this error would pop up, or why I should be, or not be, using the __init__ and/or __new__ functions would be seriously appreciated. Thanks for any help you can give in advance.

  • CPUID on Intel i7 processors

    - by StarPacker
    I'm having an issue with my CPUID-based code on newer i7-based machines. It is detecting the CPU as having a single core with 8 HT units instead of 4 cores each with 2 HT units. I must be misinterpreting the results of the CPUID information coming back from the CPU, but I can't see how. Basically, I iterate through each processor visible to Windows, set thread affinity to that thread and then make a sequence of CPUID calls. args = new CPUID_Args(); args.eax = 1; executeHandler(ref args); if (0 != (args.edx & (0x1 << 28))) { //If the 28th bit in EDX is flagged, this processor supports multiple logical processors per physical package // in this case bits 23:16 of EBX should give the count. //** EBX here is 0x2100800 logicalProcessorCount = (args.ebx & 0x00FF0000) >> 16; //** this tells me there are 16 logical processors (wrong) } else { logicalProcessorCount = 1; } apic = unchecked((byte)((0xFF000000 & args.ebx) >> 24)); if (maximumSupportedCPUID >= 4) { args = new CPUID_Args(); args.eax = 4; executeHandler(ref args); //EAX now contains 0x1C004121 coreCount = 1 + ((args.eax & 0xFC000000) >> 26); //This calculates coreCount as 8 } else { coreCount = 1; } This sequence repeats for the remainder of the CPUs in the system. Has anyone faced this before?

  • cellForRowAtIndexPath not being called on tableView reloadData

    - by BotskoNet
    I have a UITableView on one view that loads in data at the start of the application, and then later when a user enters text into a box and hits a button, I re-query the database, re-populate the original NSMutableArray that stores the data for the table. All of that is working perfectly. In some logging statements I can tell that the array has the correct information, the numberOfRowsInSection method is returning the proper count, and is being called after the reload is called. However, the cellForRowAtIndexPath is never called the second time (after the reload) and the table data is never updated. I've spent hours searching the net and I've found nothing that helps. Can anyone help? All code is at: http://github.com/botskonet/inmyspot The specific reload is being called at: http://github.com/botskonet/inmyspot/blob/master/Classes/InMySpotViewController.m Roughly Line 94 From: http://github.com/botskonet/inmyspot/blob/master/Classes/PlateFormViewController.m Roughly line 101 A bit more info: once the new data has been added to the mutablearray, if I try to start scrolling the table, it eventually dies with: "Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (29) beyond bounds (29)'" Which I assume means the table cells can't find any data in the array to match the scroll position, which seems to be because the array has the new data, but the table doesn't.

  • Output asp.net masterpage webform to html email

    - by Steve McCall
    Hi I'm having a bit of a nightmare here! I'mv trying output a webform to html using page.rendercontrol and htmltextwriter but it is resulting in a blank email. Code: StringBuilder sb = new StringBuilder(); StringWriter sw = new StringWriter(sb); HtmlTextWriter htmlTW = new HtmlTextWriter(sw); page.RenderControl(htmlTW); String content = sb.ToString(); MailMessage mail = new MailMessage(); mail.From = new MailAddress("[email protected]"); mail.To.Add("[email protected]"); mail.IsBodyHtml = true; mail.Subject = "Test"; mail.Body = content; SmtpClient smtp = new SmtpClient("1111"); smtp.Send(mail); Response.Write("Message Sent"); I also tried it by rendering a single textbox and got and error saying It needed to be within form tags (which are on the masterpage). I tried this fix: http://forums.asp.net/p/1016960/1368933.aspx#1368933 and added: public override void VerifyRenderingInServerForm(Control control) { return; } But now the errror I get is: VerifyRenderingInServerForm(Control)': no suitable method found to override Does anyone have a fix for this? I'm tearing my hair out!! Thanks, Steve

  • IDataRecord.IsDBNull causes an System.OverflowException (Arithmetic Overflow)

    - by Ciddan
    Hi! I have a OdbcDataReader that gets data from a database and returns a set of records. The code that executes the query looks as follows: OdbcDataReader reader = command.ExecuteReader(); while (reader.Read()) { yield return reader.AsMovexProduct(); } The method returns an IEnumerable of a custom type (MovexProduct). The convertion from an IDataRecord to my custom type MovexProduct happens in an extension-method that looks like this (abbrev.): public static MovexProduct AsMovexProduct(this IDataRecord record) { var movexProduct = new MovexProduct { ItemNumber = record.GetString(0).Trim(), Name = record.GetString(1).Trim(), Category = record.GetString(2).Trim(), ItemType = record.GetString(3).Trim() }; if (!record.IsDBNull(4)) movexProduct.Status1 = int.Parse(record.GetString(4).Trim()); // Additional properties with IsDBNull checks follow here. return movexProduct; } As soon as I hit the if (!record.IsDBNull(4)) I get an OverflowException with the exception message "Arithmetic operation resulted in an overflow." StackTrace: System.OverflowException was unhandled by user code Message=Arithmetic operation resulted in an overflow. Source=System.Data StackTrace: at System.Data.Odbc.OdbcDataReader.GetSqlType(Int32 i) at System.Data.Odbc.OdbcDataReader.GetValue(Int32 i) at System.Data.Odbc.OdbcDataReader.IsDBNull(Int32 i) at JulaAil.DataService.Movex.Data.ExtensionMethods.AsMovexProduct(IDataRecord record) [...] I've never encountered this problem before and I cannot figure out why I get it. I have verified that the record exists and that it contains data and that the indexes I provide are correct. I should also mention that I get the same exception if I change the if-statemnt to this: if (record.GetString(4) != null). What does work is encapsulating the property-assignment in a try {} catch (NullReferenceException) {} block - but that can lead to performance-loss (can it not?). I am running the x64 version of Visual Studio and I'm using a 64-bit odbc driver. Has anyone else come across this? Any suggestions as to how I could solve / get around this issue? Many thanks!

  • C#: How to resolve this circular dependency?

    - by Rosarch
    I have a circular dependency in my code, and I'm not sure how to resolve it. I am developing a game. A NPC has three components, responsible for thinking, sensing, and acting. These components need access to the NPC controller to get access to its model, but the controller needs these components to do anything. Thus, both take each other as arguments in their constructors. ISenseNPC sense = new DefaultSenseNPC(controller, worldQueryEngine); IThinkNPC think = new DefaultThinkNPC(sense); IActNPC act = new DefaultActNPC(combatEngine, sense, controller); controller = new ControllerNPC(act, think); (The above example has the parameter simplified a bit.) Without act and think, controller can't do anything, so I don't want to allow it to be initialized without them. The reverse is basically true as well. What should I do? ControllerNPC using think and act to update its state in the world: public class ControllerNPC { // ... public override void Update(long tick) { // ... act.UpdateFromBehavior(CurrentBehavior, tick); CurrentBehavior = think.TransitionState(CurrentBehavior, tick); } // ... } DefaultSenseNPC using controller to determine if it's colliding with anything: public class DefaultSenseNPC { // ... public bool IsCollidingWithTarget() { return worldQuery.IsColliding(controller, model.Target); } // ... }

  • Capturing unhandled exceptions in .Net 2.0. Wrong event called.

    - by SoMoS
    Hello, I'm investigating a bit about how the unhandled exceptions are managed in .Net and I'm getting unexpected results that I would like to share with you to see what do you think about. The first one is pretty simple to see. I wrote this code to do the test, just a button that throws an Exception on the same thread that created the Form: Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Throw New Exception() End Sub Private Sub UnhandledException(ByVal sender As Object, ByVal e As UnhandledExceptionEventArgs) MsgBox(String.Format("Exception: {0}. Ending: {1}. AppDomain: {2}", CType(e.ExceptionObject, Exception).Message, e.IsTerminating.ToString(), AppDomain.CurrentDomain.FriendlyName)) End Sub Private Sub UnhandledThreadException(ByVal sender As Object, ByVal e As System.Threading.ThreadExceptionEventArgs) MsgBox(String.Format("Exception: {0}. AppDomain: {1}", e.Exception.Message(), AppDomain.CurrentDomain.FriendlyName)) End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load AddHandler AppDomain.CurrentDomain.UnhandledException, AddressOf UnhandledException AddHandler Application.ThreadException, AddressOf UnhandledThreadException End Sub End Class When I execute the code inside the Visual Studio the UnhandledException is called as expected but when I execute the application from Windows the UndhanledThreadException is called instead. ¿?¿?¿¿?¿? Someone has any idea of what can be happening here? Thanks in advance.

  • BizTalk WCF Service

    - by WtFudgE
    Hi, I am getting an error in my event viewer after deploying a wcf service on our server. The Messaging Engine received an error from transport adapter "WCF-BasicHttp" when notifying the adapter with the BatchComplete event. Reason "Value does not fall within the expected range.". The thing is, this service was running before and worked fine. I just modified a schema a bit, undeployed the service and redeployed. When I then talk to this service the event viewer shows me this message. If I deploy the same service locally it works fine. Also if I browse to my service with explorer it shows no errors. Normally when the receive location is wrong or the used user isn't in the isolated biztalk usergroup it gives an error here, but this isn't the case. Anyone have any idea what I should do? My problem is pretty urgent.. I googled my errormessage but without much success. Thanks yall

  • Tricky CSS Layout

    - by Meep3D
    So I am making a website with quite a problematic layout. There are four corner images TL, TR, BL and BR indicated by black blocks. The dark orange area is the main content (to a width of 960px), with the outside area denoted by the green arrow as the browser window. See diagram: The top image represents the site at its narrowest possible - it shouldn't be allowed to be narrower than this (960px) if it is larger than the defined area there should be no scrollbars. The bottom two images represent different widths of browser. The bottom left and right black blocks (images) should be at the bottom left and right of the screen at all times, unless the width falls to 960px, in which case the BL and BR images should poke into the main area slightly. If the site is shrunk to, say 200px, the BR image should not still be poking in the right corner. At this point I don't really care about it working exactly in IE6 (I can get it roughly working) but I can't even figure out how to do it fully without Javascript or extremely experimental CSS. Currently I am using absolutely positioned div's which sort of work, but don't work quite right. I think I'd be willing to accept a bit of JS if there is no other way but I'd rather not. Answer very appreciated!

  • MS SQL 2008, join or no join?

    - by Patrick
    Just a small question regarding joins. I have a table with around 30 fields and i was thinking about making a second table to store 10 of those fields. Then i would just join them in with the main data. The 10 fields that i was planning to store in a second table does not get queried directly, it's just some settings for the data in the first table. Something like: Table 1 Id Data1 Data2 Data3 etc ... Table 2 Id (same id as table one) Settings1 Settings2 Settings3 Is this a bad solution? Should i just use 1 table? How much performance inpact does it have? All entries in table 1 would also then have an entry in table 2. Small update is in order. Most of the Data fields are of the type varchar and 2 of them are of the type text. How is indexing treated? My plan is to index 2 data fields, email (varchar 50) and author (varchar 20). And yes, all records in Table 1 will have a record in Table 2. Most of the settings fields are of the bit type, around 80%. The rest is a mix between int and varchar. The varchars can be null.

  • Preloading multiple comboboxes/listbox itemssource with enumerated values using WCF RIA Services

    - by Dale Halliwell
    I would like to be able to load several RIA entitysets in a single call without chaining/nesting several small LoadOperations together so that they load sequentially. I have several pages that have a number of comboboxes on them. These comboboxes are populated with static values from a database (for example status values). Right now I preload these values in my VM by one method that strings together a series of LoadOperations for each type that I want to load. For example: public void LoadEnums() { context.Load(context.GetMyStatusValues1Query()).Completed += (s, e) => { this.StatusValues1 = context.StatusValues1; context.Load(context.GetMyStatusValues2()).Completed += (s1, e1) => { this.StatusValues2 = context.StatusValues2; context.Load(context.GetMyStatusValues3Query()).Completed += (s2, e2) => { this.StatusValues3 = context.StatusValues3; (....and so on) }; }; }; }; While this works fine, it seems a bit nasty. Also, I would like to know when the last loadoperation completes so that I can load whatever entity I want to work on after this, so that these enumerated values resolve properly in form elements like comboboxes and listboxes. (I think) I can't do this easily above without creating a delegate and calling that on the completion of the last loadoperation. So my question is: does anyone out there know a better pattern to use, ideally where I can load all my static entitysets in a single LoadOperation?

  • Suggestions for doing async I/O with Task Parallel Library

    - by anelson
    I have some high performance file transfer code which I wrote in C# using the Async Programming Model (APM) idiom (eg, BeginRead/EndRead). This code reads a file from a local disk and writes it to a socket. For best performance on modern hardware, it's important to keep more than one outstanding I/O operation in flight whenever possible. Thus, I post several BeginRead operations on the file, then when one completes, I call a BeginSend on the socket, and when that completes I do another BeginRead on the file. The details are a bit more complicated than that but at the high level that's the idea. I've got the APM-based code working, but it's very hard to follow and probably has subtle concurrency bugs. I'd love to use TPL for this instead. I figured Task.Factory.FromAsync would just about do it, but there's a catch. All of the I/O samples I've seen (most particularly the StreamExtensions class in the Parallel Extensions Extras) assume one read followed by one write. This won't perform the way I need. I can't use something simple like Parallel.ForEach or the Extras extension Task.Factory.Iterate because the async I/O tasks don't spend much time on a worker thread, so Parallel just starts up another task, resulting in potentially dozens or hundreds of pending I/O operations; way too much! You can work around that by Waiting on your tasks, but that causes creation of an event handle (a kernel object), and a blocking wait on a task wait handle, which ties up a worker thread. My APM-based implementation avoids both of those things. I've been playing around with different ways to keep multiple read/write operations in flight, and I've managed to do so using continuations that call a method that creates another task, but it feels awkward, and definitely doesn't feel like idiomatic TPL. Has anyone else grappled with an issue like this with the TPL? Any suggestions?

  • UIView using Quartz rendering engine to display PDF has poor quality compared to original.

    - by Josh Kerr
    I'm using the quartz rendering engine to display a PDF file on the iphone using the 3.0 SDK. The result is a bit blurry compared to a PDF being shown in a UIWebView. How can I improve the quality in the UIView so that I don't need to rewrite my app to use the UIWebView. I'm using pretty much close to the example code that Apple provides. Here is some of my sample code: CGContextRef gc = UIGraphicsGetCurrentContext(); CGContextSaveGState(gc); CGContextTranslateCTM(gc, 0.0, rect.size.height); CGContextScaleCTM(gc, 1.0, -1.0); CGAffineTransform m = CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, rect, 0, false); CGContextConcatCTM(gc, m); CGContextSetGrayFillColor(gc, 1.0, 1.0); CGContextFillRect(gc, rect); CGContextDrawPDFPage(gc, page); CGContextRestoreGState(gc); Apple's tutorial code actually results in a blurry PDF view as well. If you drop the same PDF into a UIWebView you'll see it is actually sharper. Anyone have any ideas? This one issue is holding a two year development project from launching. :(

  • django {% tag %} problem

  • BIRT logging in the onFetch step of a dataset

    - by Mark Underwood
    Hi all, Im having trouble with some javascript in the onFetch step of a dataset in a BIRT report. I've added logging in the initialise step of the report in a few different ways. The runtime im using is Tivoli Common Reporting, and they supply a logging framework. Its initialised as so reportContext.setPersistentGlobalVariable("logfileName", "DateRangeParm.log"); setupLogging(); logInitialize(); debugLogger("Started logging in initialize step"); debugLogger("Date: " + new Date()); This works fine to log on the steps of the report(ie initialise, BeforeRender, AfterRender etc.) but I cant seem to log anything in the Dataset steps such as onFetch etc. Ive also tried importPackage(Packages.java.util.logging); var fileHandler = new FileHandler("/tmp/birt.log", true); var rootLogger = Logger.getLogger(""); rootLogger.addHandler(fileHandler); as the BIRT instructions tell me to do in the BIRTFAQ Once again this allowed me to log things in the main report (ie BeforeRender etc) but not in the dataset onFetch Step. Ive also tried putting the previous javascript into the onFetch and that didnt seem to work either. Its a bit of a mystery. Im running Ubuntu 9.04. IBM java 1.5. Eclipse 3.5.0 and BIRT 2.5.1. Any help would be great.

  • GWT Best Practices - MVP

    - by GWTNewbie
    A question for all the GWT gurus out there. I'm a newbie in GWT and am trying to understand the best practices of coding a GWT application. I have gone through "Large scale application development and MVP" based on Ray Ryan's talk at Google I/O 2009 and it has given me a good starting point. I downloaded the sample source code as well for the Contacts application based on the best practices listed. The application I'm trying to develop using GWT is a bit bigger (in terms of the modules involved) when compared to the sample "Contacts" application & so I want to split it up into multiple functions. I have been reading that having a single Entry point in a GWT application is a good idea, and I don't want to dump all the code in one single AppController class & one single RpcService, what would be the best approach in this situation? How would I go about dispatching the control to multiple controllers? Is there a way to achieve this using some classes in the GWT framework?

  • Intellij Javafx artifact - how do you make it?

    - by Louis Sayers
    I've been trying all day to turn my javafx application into a jar file. I'm using Java 1.7 update 7. Oracle has some information, but it just seems scattered all over the place. Intellij is almost doing the job, but I get the following error: java.lang.NoClassDefFoundError: javafx/application/Application Which seems to say that I need to tell java where the jfxrt.jar is... If I add this jar to my classpath info for the manifest build in intellij - ctrl+shift+alt+s - Artifacts - Output Layout tab - Class Path, then I get another error: Could not find or load main class com.downloadpinterest.code.Main It seems strange to have to include jfxrt.jar in my class path though... I've tried to create an ant script as well, but I feel like IntelliJ is 90% of the way there - and I just need a bit of help to figure out why I need to include jfxrt.jar, and why my Main class isn't being found (I'm guessing I need to add it to the classpath somehow?). Could anyone clue me up as to what is happening? I had a basic gui before which worked fine, but JavaFX seems to be making life complicated!

  • Store comparison in variable (or execute comparison when it's given as an string)

    - by BorrajaX
    Hello everyone. I'd like to know if the super-powerful python allows to store a comparison in a variable or, if not, if it's possible calling/executing a comparison when given as an string ("==" or "!=") I want to allow the users of my program the chance of giving a comparison in an string. For instance, let's say I have a list of... "products" and the user wants to select the products whose manufacturer is "foo". He could would input something like: Product.manufacturer == "foo" and if the user wants the products whose manufacturer is not "bar" he would input Product.manufacturer != "bar" If the user inputs that line as an string, I create a tree with an structure like: != / \ manufacturer bar I'd like to allow that comparison to run properly, but I don't know how to make it happen if != is an string. The "manufacturer" field is a property, so I can properly get it from the Product class and store it (as a property) in the leaf, and well... "bar" is just an string. I'd like to know if I can something similar to what I do with "manufacturer": storing it with a 'callable" (kind of) thing: the property with the comparator: != I have tried with "eval" and it may work, but the comparisons are going to be actually used to query a MySQL database (using sqlalchemy) and I'm a bit concerned about the security of that... Any idea will be deeply appreciated. Thank you! PS: The idea of all this is being able to generate a sqlalchemy query, so if the user inputs the string: Product.manufacturer != "foo" || Product.manufacturer != "bar" ... my tree thing can generate the following: sqlalchemy.or_(Product.manufacturer !="foo", Product.manufacturer !="bar") Since sqlalchemy.or_ is callable, I can also store it in one of the leaves... I only see a problem with the "!="

  • How do I load new pages into my current jQuery colorbox?

    - by thinkswan
    I'm having a bit of trouble loading pages into an already-existing colorbox. I have a colorbox opened by clicked a link that is bound by the following code: $("a.ajaxAddPage").colorbox({ onComplete: function(){ $('ul#addPage li a').click(function() { $.fn.colorbox({href: $(this).attr('href')}); return false; }); } }); The following HTML is loaded into that colorbox via AJAX: <div class='colorboxWindow'> <ul id='addPage'> <li><a href='addCat.php'>Add Category</a></li> <li><a href='addPage.php' class='current'>Add New Page</a></li> <li><a href='addPage2.php'>Add Another Page</a></li> </ul> <h3>Add New Page...</h3> </div> I'm trying to have each of those 3 links open in the current colorbox when they are clicked. With my onComplete binding above, this works for the first click, but the next click just opens like a normal page. If I add another onComplete to the $.fn.colorbox() call in the above code, then the 2nd click will also load in the same colorbox, but the 3rd will not. Is there a way to just bind all future clicks to open in the same colorbox? I don't know much about event binding yet. If you need clarification, please ask.

  • Making Ninject Interceptors work with async methods

    - by captncraig
    I am starting to work with ninject interceptors to wrap some of my async code with various behaviors and am having some trouble getting everything working. Here is an interceptor I am working with: public class MyInterceptor : IInterceptor { public async void Intercept(IInvocation invocation) { try { invocation.Proceed(); //check that method indeed returns Task await (Task) invocation.ReturnValue; RecordSuccess(); } catch (Exception) { RecordError(); invocation.ReturnValue = _defaultValue; throw; } } This appears to run properly in most normal cases. I am not sure if this will do what I expect. Although it appears to return control flow to the caller asynchronously, I am still a bit worried about the possibility that the proxy is unintentionally blocking a thread or something. That aside, I cannot get the exception handling working. For this test case: [Test] public void ExceptionThrown() { try { var interceptor = new MyInterceptor(DefaultValue); var invocation = new Mock<IInvocation>(); invocation.Setup(x => x.Proceed()).Throws<InvalidOperationException>(); interceptor.Intercept(invocation.Object); } catch (Exception e) { } } I can see in the interceptor that the catch block is hit, but the catch block in my test is never hit from the rethrow. I am more confused because there is no proxy or anything here, just pretty simple mocks and objects. I also tried something like Task.Run(() => interceptor.Intercept(invocation.Object)).Wait(); in my test, and still no change. The test passes happily, but the nUnit output does have the exception message. I imagine I am messing something up, and I don't quite understand what is going on as much as I think I do. Is there a better way to intercept an async method? What am I doing wrong with regards to exception handling?

  • mongodb: insert if not exists

    - by LeMiz
    Hello, Every day, I receive a stock of documents (an update). What I want to do is inserting each of them if it does not exists. I also want to keep track of the first time I inserted them, and the last time I saw them in an update. I don't want to have duplicate documents. I don't want to remove a document which has previously been saved, but is not in my update. 95% (estimated) of the records are unmodified from day to day. I am using the python driver (pymongo), for that matter. What I currently do is (pseudo-code): for each document in update: existing_document = collection.find_one(document) if not existing_document: document['insertion_date'] = now else: document = existing_document document['last_update_date'] = now my_collection.save(document) My problem is that it is very slow (40 mins for less than 100 000 records, and I have millions of them in the update). I am pretty sure there is something builtin for doing this, but the document for update() is mmmhhh.... a bit terse.... ( http://www.mongodb.org/display/DOCS/Updating ) Can someone give an advice on doing it faster ?

  • Starting Java applet directly from jar file

    - by Thomas
    The goal is to have an applet run from a jar file. The problem is that the applet only seems to want to run from an exploded jar file. Samples on the Internet suggest this applet tag: <applet code="com.blabla.MainApplet" archive="applet.jar" width="600" height="600"> This will not even try to look in the jar file and fails with: Caused by: java.io.IOException: open HTTP connection failed:http://localhost:8080/helloWord/com/blabbla/MainApplet.class at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Setting the codebase instead of the archive attribute to the jar file. Looks a bit better. However, the JVM does not realize that it has to open the jar file: <applet code="com.blabla.MainApplet" codebase="applet.jar" width="600" height="600"> Caused by: java.io.IOException: open HTTP connection failed:http://localhost:8080/helloWord/applet.jar/com/blabbla/MainApplet.class at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more How does the applet tag have to be formulated to start an applet class from inside of a jar file?

  • HTTPS Redirect Causing Error "Server cannot append header after HTTP headers have been sent"

    - by Chad
    I need to check that our visitors are using HTTPS. In BasePage I check if the request is coming via HTTPS. If it's not, I redirect back with HTTPS. However, when someone comes to the site and this function is used, I get the error: System.Web.HttpException: Server cannot append header after HTTP headers have been sent. at System.Web.HttpResponse.AppendHeader(String name, String value) at System.Web.HttpResponse.AddHeader(String name, String value) at Premier.Payment.Website.Generic.BasePage..ctor() Here is the code I started with: // If page not currently SSL if (HttpContext.Current.Request.ServerVariables["HTTPS"].Equals("off")) { // If SSL is required if (GetConfigSetting("SSLRequired").ToUpper().Equals("TRUE")) { string redi = "https://" + HttpContext.Current.Request.ServerVariables["SERVER_NAME"].ToString() + HttpContext.Current.Request.ServerVariables["SCRIPT_NAME"].ToString() + "?" + HttpContext.Current.Request.ServerVariables["QUERY_STRING"].ToString(); HttpContext.Current.Response.Redirect(redi.ToString()); } } I also tried adding this above it (a bit I used in another site for a similar problem): // Wait until page is copletely loaded before sending anything since we re-build HttpContext.Current.Response.BufferOutput = true; I am using c# in .NET 3.5 on IIS 6. enter code here

  • Where does lucene .net cache the search results?

    - by Lanceomagnifico
    Hi, I'm trying to figure out where Lucene stores the cached query results, and how it's configured to do so - and how long it caches for. This is for an ASP.NET 3.5 solution. I'm getting this problem: If I run a search and sort the result by a particular product field, it seems to work the very first time each search and sort combination is used. If I then go in and change some product attributes, reindex and run the same search and sort, I get the products returned in the same order as the very first result. example Product A is named: foo Product B is named: bar For the first search, sort by name desc. This results in: Product A Product B Now mix up the data a bit: Change names to: Product A named: bar Product B named: foo reindex verify that the index contains the changes for these two products. search Result: Product A Product B Since I changed the alphabetical order of the names, I expected: Product B Product A So I think that Lucene is caching the search results. (Which, btw, is a very good thing.) I just need to know where/how to clear these results. I've tried deleting the index files and doing an IISreset to clear the memory, but it seems to have no effect. So I'm thinking there is another set of Lucene files outside of the indexes that Lucene uses for caching. EDIT I just found out that you must create the index for field you wish to sort on as un-tokenized. I had the field as tokenized, so sorting didn't work.

  • Achieving NHibernate Nested Transactions Behavior

    - by jfneis
    Hi all, I'm trying to achieve some kind of nested transaction behavior using NHibernate's transaction control and FlushMode options, but things got a little bit confusing after too much reading, so any confirmation about the facts I list below will be very usefull. What I want is to open one big transaction that splits in little transactions. Imagine the following scenario: TX1 opens a TX and inserts a Person's record; TX2 opens a TX and updates this Person's name to P2; TX2 commits; TX3 opens a TX and updates this Person's name to P3; TX3 rollbacks; TX1 commits; I'd like to see NH sending the INSERT and the TX2 UPDATE to the database, just ignoring what TX3, as it was rolled back. I tried to use FlushMode = Never and only flushing the session after the proper Begins/Commits/Rollbacks have been demanded, but NH always update the database with the object's final state, independent of commits and rollbacks. Is that normal? Does NH really ignores transactional control when working with FlushMode = Never? I've also tried to use FlushMode = Commit and openning the nested transactions, but I discovered that, because ADO.NET, the nested transactions are, actually, always the same transaction. Note that I'm not trying to achieve a "all or nothing" behavior. I'm looking more to a savepoint way of working. Is there a way to do that (savepoints) with NH? Thank you in advance. Filipe
