  • Does HttpListener work well on Mono?

    - by billpg
    Hi everyone. I'm looking to write a small web service to run on a small Linux box. I prefer to code in C#, so I'm looking to use Mono. I don't want the overhead of running a full web server or Mono's version of ASP.NET. I'm thinking of having a single process with a thread dealing with each client connection. Shared memory between threads instead of a database. I've read a little on Microsoft's version of HttpListener and how it works with the Http.sys driver. Alas, Mono's documentation on this class is just the automated class interface with no discussion of how it works under the hood. (Linux doesn't have Http.sys, so I imagine it's implemented substantially differently.) Could anyone point me towards some resources discussing this module please? Many thanks, Bill, billpg.com (A little background to my question for the interested.) Some time ago, I asked this question, interested in keeping a long conversation open with lots of back-and-forth. I had settled on designing my own ad-hoc protocol, but people I spoke to really wanted a REST interface, even at the cost of the "Okay, send your command now" signal. So, I wondered about running ASP.NET on a Linux/Mono server, but stumbled upon HttpListener. This seemed ideal, as each "conversation" could run in a separate thread. The thread that calls HttpListener in a loop can look for which thread each incomming connection is for and pass the reference to that thread. The alternative for an ASP.NET driven service, would be to have the ASPX code pick up the state from a database, and write back the new state when it finishes. Yes, it would work, but that's a lot of overhead.

  • How do I create self-relationships in polymorphic inheritance in Elixir and Pylons?

    - by Turukawa
    I am new to programming and am following the example in the Pylons documentation on creating a Wiki. The database I want to link to the wiki was created with Elixir so I rewrote the Wiki database schema and have continued from there. In the wiki there is a requirement for a Navigation table which is inherited by Pages and Sections. A section can have many pages, while a page can only have one section. In addition, each sibling node can be chain-referenced to each other. So: Nav has "section" (OneToMany) and "before" (OneToOne - to reference preceeding node) Page has "section" (ManyToOne - many pages in one section) and inherits "before" Section inherits all from Nav The code I've written looks like this: class Nav(Entity): using_options(inheritance='multi') name = Field(Unicode(30), default=u'Untitled Node') path = Field(Unicode(255), default=u'') section = OneToMany('Page', inverse='section') after = OneToOne('Nav', inverse='before') before = OneToMany('Nav', inverse='after') class Page(Nav): using_options(inheritance='multi') content = Field(UnicodeText, nullable=False) posted = Field(DateTime, default=now()) title = Field(Unicode(255), default=u'Untitled Page') heading = Field(Unicode(255)) tags = ManyToMany('Tag') comments = OneToMany('Comment') section = ManyToOne('Nav', inverse='section') class Section(Nav): using_options(inheritance='multi') Errors received on this: sqlalchemy.exc.OperationalError: (OperationalError) table nav has no column named aftr_id u'INSERT INTO nav (name, path, aftr_id, row_type) VALUES (?, ?, ?, ?)' I've also tried: before = ManyToMany('Nav', inverse='before') on Nav in the hopes this might break the problem, but also not. The original SQLAlchemy code from the tutorial for these declarations is as follows: nav_table = schema.Table('nav', meta.metadata, schema.Column('id', types.Integer(), schema.Sequence('nav_id_seq', optional=True), primary_key=True), schema.Column('name', types.Unicode(255), default=u'Untitled Node'), schema.Column('path', types.Unicode(255), default=u''), schema.Column('section', types.Integer(), schema.ForeignKey('nav.id')), schema.Column('before', types.Integer(), default=None), schema.Column('type', types.String(30), nullable=False) ) page_table = schema.Table('page', meta.metadata, schema.Column('id', types.Integer, schema.ForeignKey('nav.id'), primary_key=True), schema.Column('content', types.Text(), nullable=False), schema.Column('posted', types.DateTime(), default=now), schema.Column('title', types.Unicode(255), default=u'Untitled Page'), schema.Column('heading', types.Unicode(255)), ) section_table = sa.Table('section', meta.metadata, schema.Column('id', types.Integer, schema.ForeignKey('nav.id'), primary_key=True), ) orm.mapper(Nav, nav_table, polymorphic_on=nav_table.c.type, polymorphic_identity='nav') orm.mapper(Section, section_table, inherits=Nav, polymorphic_identity='section') orm.mapper(Page, page_table, inherits=Nav, polymorphic_identity='page', properties={ 'comments':orm.relation(Comment, backref='page', cascade='all'), 'tags':orm.relation(Tag, secondary=pagetag_table) }) Any help is much appreciated.

  • Drupal: Template Files, Modules and Content Types for Advanced Theme

    - by theandym
    Intro I am in the process of trying to convert my first HTML/CSS design into a theme for Drupal. I have used ModX for quite a few designs and appreciate the ability to create different page templates and custom variables to be assigned to those templates. However I seem to be having some issues making the transition. The site I am working on theming in Drupal is for a real estate agent. Each page/section will have a different set of content associated with it and will need to display only that content. For example, there will be a page for current listings, each of which will be formatted by a custom content type. However, when I call the content on the home page (or on other pages) I do not want to see this listing data. Layout The layout of the site and the regions associated with each page/section is as follows: Home Spotlight Featured 1 Featured 2 About Spotlight Bios - Profiles of each agent (each will be a node with name, contact info, pic, etc) listed on the page; multiple nodes listed Sidebar Listings Spotlight Listings - Profiles of properties (each will be a node with locations, basic info, pic, etc) listed on the page; multiple nodes listed Sidebar Services Spotlight Content - general paragraph text area Sidebar News/Blog News/Blog Items - List of stories with summaries and links to full article Sidebar Each page/section will use the same header and footer. Issue I have done some reading on Drupal, custom content types (and CCK), Views, and Pathauto. However I have not been able to get a clear picture of how to put it all together to accomplish what I am attempting. What I really would like to know is which modules to use, how best to use them, which elements I need to use where, and what template files I should be using to theme the elements I need to use. Any help or reference to useful resources would be much appreciated.

  • Can I use Ninject ConstructorArguments with strong naming?

    - by stiank81
    Well, I don't know if "strong naming" is the right term, but what I want to do is as follows. Currently I use ConstructorArgument like e.g. this: public class Ninja { private readonly IWeapon _weapon; private readonly string _name; public Ninja(string name, IWeapon weapon) { _weapon = weapon; _name = name; } // ..more code.. } public void SomeFunction() { var kernel = new StandardKernel(); kernel.Bind<IWeapon>().To<Sword>(); var ninja = ninject.Get<Ninja>(new ConstructorArgument("name", "Lee")); } Now, if I rename the parameter "name" (e.g. using ReSharper) the ConstructorArgument won't update, and I will get a runtime error when creating the Ninja. To fix this I need to manually find all places I specify this parameter through a ConstructorArgument and update it. No good, and I'm doomed to fail at some point even though I have good test coverage. Renaming should be a cheap operation. Is there any way I can make a reference to the parameter instead - such that it is updated when I rename the parameter?

  • Unit Testing (xUnit) an ASP.NET Mvc Controller with a custom input model?

    - by Danny Douglass
    I'm having a hard time finding information on what I expect to be a pretty straightforward scenario. I'm trying to unit test an Action on my ASP.NET Mvc 2 Controller that utilizes a custom input model w/ DataAnnotions. My testing framework is xUnit, as mentioned in the title. Here is my custom Input Model: public class EnterPasswordInputModel { [Required(ErrorMessage = "")] public string Username { get; set; } [Required(ErrorMessage = "Password is a required field.")] public string Password { get; set; } } And here is my Controller (took out some logic to simplify for this ex.): [HttpPost] public ActionResult EnterPassword(EnterPasswordInputModel enterPasswordInput) { if (!ModelState.IsValid) return View(); // do some logic to validate input // if valid - next View on successful validation return View("NextViewName"); // else - add and display error on current view return View(); } And here is my xUnit Fact (also simplified): [Fact] public void EnterPassword_WithValidInput_ReturnsNextView() { // Arrange var controller = CreateLoginController(userService.Object); // Act var result = controller.EnterPassword( new EnterPasswordInputModel { Username = username, Password = password }) as ViewResult; // Assert Assert.Equal("NextViewName", result.ViewName); } When I run my test I get the following error on my test fact when trying to retrieve the controller result (Act section): System.NullReferenceException: Object reference not set to an instance of an object. Thanks in advance for any help you can offer!

  • Making ANTLR generated class files into one jar file.

    - by prosseek
    With ANTLR, I get some java class files after compilation. And I need to make all the class files into one jar file. I make manifest.mf file that has one line "Main-class: Test" to indicate the main file. I run 'jar cmf manifest.mf hello.jar *.class' to get hello.jar file. But when I try to run 'java -jar hello.jar', I get the following error messages. $ java -jar hello.jar Exception in thread "main" java.lang.NoClassDefFoundError: Test Caused by: java.lang.ClassNotFoundException: Test at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) What's wrong? I get correct result when I run 'java Test'. The example that I used is the source code from the book 'The Definitive ANTLR Reference' that you can download from http://www.pragprog.com/titles/tpantlr/source_code The example is in /tour/trees/. I get a bunch of class files after compiling g and java files.

  • Getting a connection from a Sybase datasource in WAS 6.1 fails with message "User name property miss

    - by Abel Morelos
    I have a standalone application that needs to connect to a Sybase database via a datasource, I'm trying to connect using getConnection() and get the connection from this Sybase datasource which is hosted in WAS 6.1, sadly I'm getting an error JZ004 - Sybase(R) jConnect for JDBC(TM) Programmer's Reference: SQL Exception and Warning Messages JZ004 error message is: User name property missing in DriverManager.getConnection(..., Properties) Action: Provide the required user property. As you can see, this is not a connectivity (so we can discard JNDI or lookup problems), but rather a configuration problem. For my Sybase datasource in WAS 6.1 I have set up the proper authentication alias (Component-managed Authentication Alias), and I know the credentials are alright, "Test Connection" is successful for this datasource. Somebody had a similar problem and was because of the authentication alias- http://forum.springsource.org/showthread.php?t=39915 Next, I tried calling getConnection() but now I provided the credentials like getConnection(user, password)... and this time it worked!!! So I suspect that somehow WAS 6.1 is not picking or taking the authentication info I set in the datasource as mentioned before. If you think that maybe getConnection(user, password) should be OK for my case, well, that's not the case since I have a requirement to keep the credentials in the server, the standalone application only needs to know the JNDI information to lookup the datasource. Please let me know if have faced a similar problem, or what would you suggest me to do. Thanks.

  • Dynamically Resizing an Iframe

    - by regex
    Hello All, I can see that this question has been asked several times, but none of the proposed solutions seem to work for the site I am building, so I am reopening the thread. I am attempting to size an iframe based on the height of it's content. Both the page that contains the iframe and it's source page exist on the same domain. I have tried the proposed solutions in each of the following threads: Resize iframe height according to content height in it Resizing an iframe based on content I believe that the solutions above are not working because of when the reference to body.clientHeight is made, the browser has not actually determined the height of the document. Here is the code I am using: var ifmBlue = document.getElementById("ifmBlue"); ifmBlue.onload = resizeIframe; function resizeIframe() { var ifmBlue = document.getElementById("ifmBluePill"); var ifmDiv = ifmBlue.contentDocument.getElementById("main"); var height = ifmDiv.clientHeight; ifmBlue.style.height = (ifmBlue.contentDocument.body.scrollHeight || ifmBlue.contentDocument.body.offsetHeight || ifmBlue.contentDocument.body.parentNode.clientHeight || height || 500) + 5 + 'px'; } If I debug the script using fire debug, the client height of the iframe.contentDocument's main div is 0. Additionally, body.offsetHieght, & body.scrollHeight are 0. However, after the script is finished running, if I inspect the DOM of the HTML iframe element (using fire debug) I can see that the body's clientHeight is 456 and the inner div's clientHeight is 742. This leads me to believe that these values are not yet set when iframe.onload is fired. So, per one of the threads above, I moved the code into the body.onload event handler of the iframe's source page. This solution also did not work. Any help you can provide is much appreciated. Thanks, CJ

  • Drawing half of a Bezier path in Raphael

    - by Fibericon
    Let's say I have a cubic Bezier path as follows (formatted for use with the Raphael path function): M55 246S55 247 55 248 Just an example. This was taken from my drawing application, where I use the cursor to draw a line when the user holds the mouse button down, kind of like a pencil or marker. I'm using jquery's mousemove event to draw the line between two points every time the user moves the mouse. There is another (the reference point) that is taken before the line is drawn, so that the Bezier curve can be created. Here's my question: is it possible to make Raphael only draw half of a given path? I'm aware of the getSubpath() function, but if my understanding of Bezier curves is correct, it would be rather difficult to calculate the second argument. The problem with the animate function is that it creates double lines (that is, it creates the curved line that I want, and the boxy line around it which should not be shown, possibly because the mouse is being moved faster than the animation can handle). Of course, if my approach itself is flawed in some way (or my understanding of the possible solutions), I'd like to hear it. Any help would be appreciated.

  • How do I correctly modify a custom cocoa framework?

    - by Septih
    Hello, I'm working with the very-useful ID3 framework in my cocoa project. There's one tiny thing I'd like to modify in it, but I can't seem to get the changes I've made to apply to the built framework. The source code provided with the framework comes with an Xcode project, so I've opened that up and for testings sake put an NSLog(@"hello"); in. It's definetly in a place where it will be called and there are other NSLog() calls in the framework that show up so it's not just console output being supressed. To build the framework once modified I've first cleaned the build folder, made sure that it's actually removed the files, and then built it. Then in the Xcode project I'm using the framework in, I've deleted the old reference and added a new one to the framework that's freshly built. Running my project with the newly build framework doesn't call the modified framework code. I've tried with both the Development and Deployment builds that are part of the framework Xcode project. My gut instinct is that the executable that the framework code is compiled into is being cached somehow. But as I'm fairly unfamiliar with the workings of frameworks, I'm not really sure where to look.

  • How to push this view controller ?

    - by hib
    Hello all, I am caught in a strange requirement .See the following view hierarchy and scenario . I have a tab bar application in which I have three tabs . In first tab I am showing some content with a small image title and date (uitableview in navigation controller). In the detail view of that controller there are more buttons that shows different sorts of detail like gallery button and , more details button and some , more button . On tapping each button I will push each individual view controller in the main navigation controller . Now on the horizontal orientation I am showing same list of content but in the cover flow ( in modal view controller ) fashion like the ipod application . On tapping any image we will show the same buttons like gallery and more details and tapping on it will show the new controller with the following code : UINavigationController *modalNavController = [[UINavigationController alloc] initWithRootViewController:myPhotoController]; UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(backButtonPressed)]; myPhotoController.navigationItem.leftBarButtonItem = backButton; [backButton release]; if([self.modalViewController isViewLoaded]){ [self dismissModalViewControllerAnimated:YES]; } modalNavController.navigationBar.barStyle = UIBarStyleBlackOpaque; [self presentModalViewController:modalNavController animated:YES]; [modalNavController release]; All this is working nicely . but when I get back the device in vertical orientation . the main modal controller will be dismissed and all the containing modal controller also will be dismissed if they are open or not . Instead of this what I want is If chooses an item in the coverflow and then if chooses gallery and if I put the device in vertical orientaion the gallery should be in the navigation hierarchy that drove me to the main list and gallery should be in horizonatal fashion . So what I want to do is that just to push the gallery controller in the main navigation hierarchy instead of showing from a madal controller . If someone wants reference then see the application "net a porter" I want to do like that . Just tell me how the controller hierarchy is working in that app . I need the help . Thanks

  • getting proxies of the correct type in nhibernate

    - by Nir
    I have a problem with uninitialized proxies in nhibernate The Domain Model Let's say I have two parallel class hierarchies: Animal, Dog, Cat and AnimalOwner, DogOwner, CatOwner where Dog and Cat both inherit from Animal and DogOwner and CatOwner both inherit from AnimalOwner. AnimalOwner has a reference of type Animal called OwnedAnimal. Here are the classes in the example: public abstract class Animal { // some properties } public class Dog : Animal { // some more properties } public class Cat : Animal { // some more properties } public class AnimalOwner { public virtual Animal OwnedAnimal {get;set;} // more properties... } public class DogOwner : AnimalOwner { // even more properties } public class CatOwner : AnimalOwner { // even more properties } The classes have proper nhibernate mapping, all properties are persistent and everything that can be lazy loaded is lazy loaded. The application business logic only let you to set a Dog in a DogOwner and a Cat in a CatOwner. The Problem I have code like this: public void ProcessDogOwner(DogOwner owner) { Dog dog = (Dog)owner.OwnedAnimal; .... } This method can be called by many diffrent methods, in most cases the dog is already in memory and everything is ok, but rarely the dog isn't already in memory - in this case I get an nhibernate "uninitialized proxy" but the cast throws an exception because nhibernate genrates a proxy for Animal and not for Dog. I understand that this is how nhibernate works, but I need to know the type without loading the object - or, more correctly I need the uninitialized proxy to be a proxy of Cat or Dog and not a proxy of Animal. Constraints I can't change the domain model, the model is handed to me by another department, I tried to get them to change the model and failed. The actual model is much more complicated then the example and the classes have many references between them, using eager loading or adding joins to the queries is out of the question for performance reasons. I have full control of the source code, the hbm mapping and the database schema and I can change them any way I want (as long as I don't change the relationships between the model classes). I have many methods like the one in the example and I don't want to modify all of them. Thanks, Nir

  • VS2010: "Select Resource" dialog & resx location

    - by Dav
    Got two issues with the VS2010 / VS2008 select resource dialog - the one that appears when you want to add an image to a button in a WinForms app for example. Give me my files back! It only seems to see the default project resources file (Properties\Resources.resx), and resx files in project root (say MyProject\famfamfam.resx). We have quite a few icons all over the app, and because some of them come from different icon sets (like famfamfam), and some are related to this project only we'd like to keep them separate. For that same reason (keeping solution neat & tidy) we want to store these extra resource files in the Resources folder (eg. Resources\famfamfam.resx). However, we'd also like to keep using the Select Resource dialog :-) Because it does not see the 'extra' resource files, we're having to select a 'fake' icon now (from the global Resources.resx file) and then manually change that to reference the right icon in .Designer.cs. As you can imagine, this is a pain. Stop modifying my files! Second issue is a bit more annoying. We use the excellent MultiLang add-in for Visual Studio to globalize our app. It stores its translations in MultiLang.resx & MultiLang.XY.resx files in the project root, where XY is a language code, eg. .cs.resx for Czech. These have to be set to No code generation access modifier. What Select Resource seems to be doing is set all .resx files it can find to Internal. Exec summary Is there a way to convince Select Resource dialog to look for extra .resx files anywhere besides the project root? Is there any way to stop it from modifying the access modifier of the resources it does see (other than file a bug with MS)? Thanks in advance for any suggestions!

  • Mysterious extra hashtable entry

    - by Harm De Weirdt
    Good evening everyone, I'm back :) Let me explain my problem. I have a hashtable in wich I store the products a costumors buys (%orders). It uses the productcode as key and has a reference to an array with the other info as value. At the end of the program, I have to rewrite the inventory to the updated version (i.e. subtract the quantity of the bought items) This is how I do this: sub rewriteInventory{ open(FILE,'>inv.txt'); foreach $key(%inventory){ print FILE "$key\|$inventory{$key}[0]\|$inventory{$key}[1]\|$inventory{$key}[2]\n" } close(FILE); } where $inventory{$key}[x] is 0 - Title, 1 - price, 2 - quantity. The problem here is that when I look at inv.txt afterwards, I see things like this: CD-911|Lady Gaga - The Fame|15.99|21 ARRAY(0x145030c)||| BOOK-1453|The Da Vinci Code - Dan Brown|14.75|12 ARRAY(0x145bee4)||| Where do these "ARRAY(0x145030c)|||" entries come from? Or more important, how do I get rid of them? This is the last part of this school task, I had so much problems programming all this and this stupid little thing comes up now and I'm really fed up with this whole Perl thing. (this aside :p) I hope someone can help me :) Fuji

  • How are Scala closures transformed to Java objects?

    - by iguana
    I'm currently looking at closure implementations in different languages. When it comes to Scala, however, I'm unable to find any documentation on how a closure is mapped to Java objects. It is well documented that Scala functions are mapped to FunctionN objects. I assume that the reference to the free variable of the closure must be stored somewhere in that function object (as it is done in C++0x, e.g.). I also tried compiling the following with scalac and then decompiling the class files with JD: object ClosureExample extends Application { def addN(n: Int) = (a: Int) => a + n var add5 = addN(5) println(add5(20)) } In the decompiled sources, I see an anonymous subtype of Function1, which ought to be my closure. But the apply() method is empty, and the anonymous class has no fields (which could potentially store the closure variables). I suppose the decompiler didn't manage to get the interesting part out of the class files... Now to the questions: Do you know how the transformation is done exactly? Do you know where it is documented? Do you have another idea how I could solve the mystery?

  • testing if constructor in constructor chain

    - by Delan Azabani
    I'm attempting to implement a GTK+ inspired widget toolkit for the web in JavaScript. One of the constructor chains goes gtk.widget => gtk.container => gtk.bin => gtk.window Every gtk.widget has a showAll method, which, if and only if the widget is a gtk.container or derivative (such as gtk.bin or gtk.window), will recursively show the children of that widget. Obviously, if it isn't a gtk.container or derivative, we shouldn't do anything because the widget in question can't contain anything. For reference, here is my inheritance function; it's probably not the best, but it's a start: function inherit(target, parent) { target.prototype = new parent; target.prototype.constructor = target; } I know that I can check for the direct constructor like this: if (this.constructor === gtk.container) ... However, this only tests for direct construction and not, say, if the object is a gtk.bin or gtk.window. How can I test whether gtk.container is somewhere up in the constructor chain?

  • Visual Studio 2008 / ASP.NET 3.5 / C# -- issues with intellisense, references, and builds

    - by goober
    Hey all, Hoping you can help me -- the strangest thing seems to have happened with my VS install. System config: Windows 7 Pro x64, Visual Studio 2008 SP1, C#, ASP.NET 3.5. I have two web site projects in a solution. I am referencing NUnit / NHibernate (did this by right-clicking on the project and selecting "Add Reference". I've done this for several projects in the past). Things were working fine but recently stopped working and I can't figure out why. Intellisense completely disappears for any files in my App_Code directory, and none of the references are recognized (they are recognized by any file in the root directory of the web site project. Additionally, pretty simple commands like the following (in Page_Load) fail (assume TextBox1 is definitely an element on the page): if (Page.IsPostBack) { str test1; test1 = TextBox1.Text; } It says that all the page elements are null or that it can't access them. At first I thought it was me, but due to the combination of issues, it seems to be Visual Studio itself. I've tried clearing the temp directories & rebuilding the solution. I've also tried tools -- options -- text editor settings to ensure intellisense is turned on. I'd appreciate any help you can give! Thanks, Sean

  • How can I use System.Web.Caching.Cache in a Console application?

    - by Ron Klein
    Context: .Net 3.5, C# I'd like to have caching mechanism in my Console application. Instead of re-inventing the wheel, I'd like to use System.Web.Caching.Cache (and that's a final decision, I can't use other caching framework, don't ask why). However, it looks like System.Web.Caching.Cache is supposed to run only in a valid HTTP context. My very simple snippet looks like this: using System; using System.Web.Caching; using System.Web; Cache c = new Cache(); try { c.Insert("a", 123); } catch (Exception ex) { Console.WriteLine("cannot insert to cache, exception:"); Console.WriteLine(ex); } and the result is: cannot insert to cache, exception: System.NullReferenceException: Object reference not set to an instance of an object. at System.Web.Caching.Cache.Insert(String key, Object value) at MyClass.RunSnippet() So obviously, I'm doing something wrong here. Any ideas? Update: +1 to most answers, getting the cache via static methods is the correct usage, namely HttpRuntime.Cache and HttpContext.Current.Cache. Thank you all!

  • Get available screen area in autohotkey

    - by Herms
    I'm trying to write a few simple AutoHotkey scripts for moving windows around, and I'm having trouble getting the correct screen size values. I'm trying to get the size of the usable area on the screen (generally the full screen resolution minus the taskbar, and maybe any other docked windows like the sidebar in Vista). Neither of the methods I've found for getting the screen width seems to work. None of the 3 methods I found to get the screen size are giving me the right values. Here's the test script I'm using (running on XP with the taskbar on the bottom at its default size): #7:: WinMove A,,0,0,A_ScreenWidth,A_ScreenHeight return #8:: ;SM_CXMAXIMIZED and SM_CYMAXIMIZED SysGet, ScreenWidth, 61 SysGet, ScreenHeight, 62 WinMove A,,0,0,ScreenWidth,ScreenHeight return #9:: ;SM_CXFULLSCREEN and SM_CYFULLSCREEN SysGet, ScreenWidth, 16 SysGet, ScreenHeight, 17 WinMove A,,0,0,ScreenWidth,ScreenHeight return #7 causes the window to take up the entire resolution, so it overlaps the taskbar. #8 causes the width to be larger than the resolution (I see the window's right edge show up on my secondary monitor) and the height is slightly too large, so the window partially overlaps the taskbar area. Looks like this is correct except for not taking into account the window decorations at the edges. #9 seems to have the correct width, but the height is too short. It looks like it's subtracting the taskbar's height from the resolution's height, but then subtracting another 30 pixels from it. I could just use what I have in #9 and add 30 to the height I get, but that feels too much like a hack that would break in other configurations. It seems like there has to be a way to get the available screen size properly, but I can't find it in AutoHotkey. For reference, this seems to give me what I need in Java: Toolkit.getDefaultToolkit().getScreenSize();

  • Jmeter is not extracting correctly the value with the reg ex extractor.

    Jmeter is not extracting correctly the value with the reg ex. When I play with this reg ex (NAME="token" \s value="([^"]+?)") in reg ex coach with the following html everything work fine but when adding the reg with a reg ex extrator to the request he doesn't found the value even if it's the same html in output. <HTML>< script type="text/javascript" > function dostuff(no, applicationID) { submitAction('APPS_NAME' , 'noSelected=' + no + '&applicationID=' + applicationID); }< /script> <FORM NAME="baseForm" ACTION="" METHOD="POST"> <input type="hidden" NAME="token" value="fc95985af8aa5143a7b1d4fda6759a74" > <div id="loader" align="center"> <div> <strong style="color: #003366;">Loading...</strong> </div> <img src="images/initial-loader.gif" align="top"/> </div> <BODY ONLOAD="dostuff('69489','test');"> From the reg ex extractor reference name: token Regex: (NAME="token" \s value="([^"]+?)") template : $2$ match no.:1 Default value: wrong-token The request following my the POST of the previous code is returning : POST data: token=wrong-token in the next request in the tree viewer. But when I check a the real request in a proxy the token is there. Note : I tried the reg ex without the bracket and doesn't worked either. Do anybody have a idea whats wrong here ? Why jmeter can't find my token with the reg ex extrator ?

  • Django: Overriding the save() method: how do I call the delete() method of a child class

    - by Patti
    The setup = I have this class, Transcript: class Transcript(models.Model): body = models.TextField('Body') doPagination = models.BooleanField('Paginate') numPages = models.PositiveIntegerField('Number of Pages') and this class, TranscriptPages(models.Model): class TranscriptPages(models.Model): transcript = models.ForeignKey(Transcript) order = models.PositiveIntegerField('Order') content = models.TextField('Page Content', null=True, blank=True) The Admin behavior I’m trying to create is to let a user populate Transcript.body with the entire contents of a long document and, if they set Transcript.doPagination = True and save the Transcript admin, I will automatically split the body into n Transcript pages. In the admin, TranscriptPages is a StackedInline of the Transcript Admin. To do this I’m overridding Transcript’s save method: def save(self): if self.doPagination: #do stuff super(Transcript, self).save() else: super(Transcript, self).save() The problem = When Transcript.doPagination is True, I want to manually delete all of the TranscriptPages that reference this Transcript so I can then create them again from scratch. So, I thought this would work: #do stuff TranscriptPages.objects.filter(transcript__id=self.id).delete() super(Transcript, self).save() but when I try I get this error: Exception Type: ValidationError Exception Value: [u'Select a valid choice. That choice is not one of the available choices.'] ... and this is the last thing in the stack trace before the exception is raised: .../django/forms/models.py in save_existing_objects pk_value = form.fields[pk_name].clean(raw_pk_value) Other attempts to fix: t = self.transcriptpages_set.all().delete() (where self = Transcript from the save() method) looping over t (above) and deleting each item individually making a post_save signal on TranscriptPages that calls the delete method Any ideas? How does the Admin do it? UPDATE: Every once in a while as I'm playing around with the code I can get a different error (below), but then it just goes away and I can't replicate it again... until the next random time. Exception Type: MultiValueDictKeyError Exception Value: "Key 'transcriptpages_set-0-id' not found in " Exception Location: .../django/utils/datastructures.py in getitem, line 203 and the last lines from the trace: .../django/forms/models.py in _construct_form form = super(BaseInlineFormSet, self)._construct_form(i, **kwargs) .../django/utils/datastructures.py in getitem pk = self.data[pk_key]

  • Automatic web form testing/filling

    - by Polatrite
    I recently became lead on getting an inordinate amount of testing done in a very short period of time. We have many different web forms, using custom (Telerik) controls that need to be tested for proper data validation and sensible handling of the data. Some of the forms are several pages long with 30-80 different controls for data entry. I am looking for a software solution (that is free) that would allow me to automate the process of filling in these forms by designing a script, or using a UI. The other requirement is that I can't use any browsers but IE6 (terrible, I know). I have previously used AutoHotkey to great success for automatic Windows form testing, since Autohotkey's API allows you to directly reference controls on the Windows form. However Autohotkey does not have similar support for web forms (everything is just one big "InternetExplorer" control). While I would prefer that I could script some variance in the data to help serialize each test, it's not necessary, as I could go back through and manually edit a field or two (plus "break" whatever control I'm currently testing) to serialize each test. If you've ever seen Spawner: http://forge.mysql.com/projects/project.php?id=214 It's almost exactly the sort of thing I'm looking for (Spawner generates dummy SQL data, as opposed to dummy webform data) - but I won't be picky, I've got a really short deadline to meet and had this thrust in my lap just today. ;) Edit1: One of the challenges of just using Autohotkey to simulate keyboard input (tabbing through controls) is that some controls don't currently have tab index (bug), and some controls cause a page reload after modification, resulting in inconsistent control focus (tabbing screwed up). Our application makes heavy use of page reloads to populate fields (select a location, it auto-populates a city, for example).

  • WCF Data Services - neither .Expand or .LoadProperty seems to do what I need

    - by TomK
    I am building a school management app where they track student tardiness and absences. I've got three entities to help me in this. A Students entity (first name, last name, ID, etc.); a SystemAbsenceTypes entity with SystemAbsenceTypeID values for Late, Absent-with-Reason, Absent-without-Reason; and a cross-reference table called StudentAbsences (matching the student IDs with the absence-type ID, plus a date, and a Notes field). What I want to do is query my entities for a given student, and then add up the number of each kind of Absence, for a given date range. I prepare my currentStudent object without a problem, then I do this... Me.Data.LoadProperty(currentStudent, "StudentAbsences") 'Loads the cross-ref data lblDaysLate.Text = (From ab In currentStudent.StudentAbsences Where ab.SystemAbsenceTypes.SystemAbsenceTypeID = Common.enuStudentAbsenceTypes.Late).Count.ToString ...and this second line fails, complaining it has no value for an object. I presume the problem is that while it DOES see that there are (let's say) four absences for the currentStudent (ie, currentStudent.StudentAbsences.Count = 4) -- it can't yet "peer into" each one of the absences to look at its type. How do I use .Expand or .LoadProperty to make this happen? I tried fiddling with .LoadProperty but it doesn't take a two-level syntax like so... Data.LoadProperty(currentStudent,"StudentAbsences.SystemAbsenceTypeID") or the like. Is there some other technique?

  • Java: Is clone() really ever used? What about defensive copying in getters/setters?

    - by GreenieMeanie
    Do people practically ever use defensive getters/setters? To me, 99% of the time you intend for the object you set in another object to be a copy of the same object reference, and you intend for changes you make to it to also be made in the object it was set in. If you setDate(Date dt) and modify dt later, who cares? Unless I want some basic immutable data bean that just has primitives and maybe something simple like a Date, I never use it. As far as clone, there are issues as to how deep or shallow the copy is, so it seems kind of "dangerous" to know what is going to come out when you clone an Object. I think I have only used clone() once or twice, and that was to copy the current state of the object because another thread (ie another HTTP request accessing the same object in Session) could be modifying it. Edit - A comment I made below is more the question: But then again, you DID change the Date, so it's kind of your own fault, hence whole discussion of term "defensive". If it is all application code under your own control among a small to medium group of developers, will just documenting your classes suffice as an alternative to making object copies? Or is this not necessary, since you should always assume something ISN'T copied when calling a setter/getter?

  • typed-dataset initializer problem with C# windows app.

    - by Eyla
    Greetings, I'm working in windows application using C#. I have typed-dataset called packetsDBDataSet and it has table adapter called packetsTableAdapter with method to insert data called InsertPackets(). when I want to insert new data I used a code that I used before with asp.net page and it was working ok but not I'm getting error. here is the code: public packetsDBDataSetTableAdapters.packetsTableAdapter ds = new packetsDBDataSetTableAdapters.packetsTableAdapter(); public packetsDBDataSet.packetsDataTable insert = ds.InsertPackets(); and here is the error: Error 1 A field initializer cannot reference the non-static field, method, or property 'Packets.Form1.ds' C:\Users\Ali\Documents\Visual Studio 2008\Projects\Packets-3\Packets\Packets\Form1.cs 26 59 Packets I already included to my project: using Packets; using Packets.packetsDBDataSetTableAdapters; please advice to solve this problem. Update : I also tried : public packetsDBDataSetTableAdapters.packetsTableAdapter ds = new packetsDBDataSetTableAdapters.packetsTableAdapter(); ds.InsertPackets("1","2","3"); and I'm getting this error: Error 1 Invalid token '(' in class, struct, or interface member declaration C:\Users\Ali\Documents\Visual Studio 2008\Projects\Packets-3\Packets\Packets\Form1.cs 28 29 Packets
