  • Send parameters in order in HTTPService

    - by Suraj Chandran
    I am trying to work with a simple HTTPService. The problem is that my webservice is conscious of the order of arguments it gets. I will tell the problem with an example: var service:HTTPService = new HTTPService(); var params:Object = new Object(); params.rows = 0; params.facet = "true"; service.send(params); Note that in the above code I have mentioned the parameter rows before facet, but the url I recieve is facet=true&rows=0. So I recieve the argument rows before facet and hence my webservice does not work. I figured out that the contents of array is always sent in alphabetical order, which I dont want. Is there any way I can achieve explict ordering of parameters sent? Note that I am not in power of changing the logic of webservice(its basically a RPC service supporting both desktop and web client). Thanks.

  • get current logged in userID in aspnet mvc membership

    - by FosterZ
    hi, i am trying to show a list of users of my application "school", when admin logs in then he can view all the users in list but when school principals logins, he should get only users of his school, So i thought to get the current loggedIn userId first and then by that userId i'll get schoolId since userId is foreign key in school table...once i'll get the schoolId i can show the members of that school. But my problem is how to get the UserID of currently loggedIn. I'm using MVC 1.0 Asp.Net -- "Membership" if my logic above is wrong then please tell me the alternate good idea, so that principal can see only his users list..

  • How to save, retrieve and draw an image using Java and PostgreSQL?

    - by spderosso
    Given an object X; I want this object to have an image. The image must be stored in the database. I can't store the path, the actual image must be in the database. My question can be answered by answering the following subquestions: a). What type of field should I put in the database? (e.g VARCHAR) b) What type of object should I use for storing and manipulating the image (at an object layer)? (e.g java.awt.Image) c) How do I create an object of the type selected (answer of question b) from the data obtained from the database? d) How do I save an object of the type selected (answer of question b) to the database? e) How do I draw the image on a web page? I am using PostgreSQL, Java and it is a web application. Thanks!

  • Calling CONTENT_SCRIPT JS From BROWSER_ACTION Popup HTML

    - by Aristotle
    I'm working on a Google Chrome Extension and would like to get an HTML from within my popup HTML to call functions within my loaded javascript file. My manifest follows: { "name": "Extension", "version": "1.0", "description": "Extension", "browser_action": { "default_icon": "icon.png", "default_title": "Ext", "popup": "popup.html" }, "content_scripts": [{ "matches": ["http://*/*"], "css": ["ext.css"], "js": ["jquery.js","scripts.js"] }], "permissions": [ "http://*/*" ] } As you can see I'm loading in a local copy of jQuery, along with another javascript file for my own personal logic. My popup document looks like this: <select id="values"> <option>Foo</option> <option>Bar</option> </select> And the contents of my scripts.js file follow: $(function(){ $("#values").change(function(){ alert("Foo"); }); }); This isn't doing what I expect though - alerting "Foo" anytime I change a value in my popup HTML. How can I get these two files to communicate with eachother? Or can they at all?

  • Need to get .obj file names of Executable(which one is crrently executing) at runtime programaticall

    - by Usman
    Suppose I have a VC++ project contains no of(say e.g 5) Source files(.cpp files),it will generate 5 .obj files(obj files corresponding to my .cpp's files not all kernel and OS layers including .obj files) e.g my project includes xyz_1.cpp,xyz_2.cpp,xyz_3.cpp,xyz_4.cpp,it will corresponds 4 respective .objs. By programtaically HOW CAN I TAKE AND GET THE NAMES OF THESE 4 .OBJ files at runtime(On run time I need to check how many obj files & names of those objs). REMEMBER I DON'T NEED ALL KERNEL AND OS LAYER .OBJS I ONLY NEED OBJS OF MY .CPPs. Regards Usman

  • Delayed "rendering" of WPF/Silverlight Dependency Properties?

    - by Aardvark
    Is there a way to know the first time a Dependency Property is accessed through XAML binding so I can actually "render" the value of the property when needed? I have an object (class derived from Control) that has several PointCollection Dependency Properties that may contain 100's or 1000's of points. Each property may arrange the points differently for use in different types shapes (Polyline, Polygon, etc - its more complicated then this, but you get the idea). Via a Template different XAML objects use TemplateBinding to access these properties. Since my object uses a Template I never know what XAML shapes may be in use for my object - so I never know what Properties they may or may not bind to. I'd like to only fill-in these PointCollections when they are actually needed. Normally in .NET I'd but some logic in the Property's getter, but these are bypassed by XAML data binding. I need a WPF AND Silverlight compatible solution. I'd love a solution that avoids any additional complexities for the users of my object.

  • XStream <-> Alternative binary formats (e.g. protocol buffers)

    - by sehugg
    We currently use XStream for encoding our web service inputs/outputs in XML. However we are considering switching to a binary format with code generator for multiple languages (protobuf, Thrift, Hessian, etc) to make supporting new clients easier and less reliant on hand-coding (also to better support our message formats which include binary data). However most of our objects on the server are POJOs with XStream handling the serialization via reflection and annotations, and most of these libraries assume they will be generating the POJOs themselves. I can think of a few ways to interface an alternative library: Write an XStream marshaler for the target format. Write custom code to marshal the POJOs to/from the classes generated by the alternative library. Subclass the generated classes to implement the POJO logic. May require some rewriting. (Also did I mention we want to use Terracotta?) Use another library that supports both reflection (like XStream) and code generation. However I'm not sure which serialization library would be best suited to the above techniques.

  • What trivial real-life example do you use to explain programming to total non-programmers?

    - by anon
    Programmers seem to live in a world of their own (as this site indicates), with their own vibrant culture - and their own premises and vocabulary. Once we've been in the field for a bit, we take a lot of things for granted. But I'm often faced with the question "What do you do?" Or "What is programming?" I generally try to answer this with a small, often trivial, real-world example of how programming is prevalent in our everyday lives and keeps things running. The example I use most often is an elevator - someone has to program the logic of that... And I've seen elevators that are "smart" and ones that are quite backwards and foolish. (And you can easily understand if/decision and looping from that... incorporates a lot of important programming concepts in a very small example.) I've sometimes heard people use traffic lights as an example. What example do you / would you use to explain the concept of programming to someone completely clueless?

  • Hex representation of Euro Symbol €

    - by Rahul
    Hi I was using XVI32 (Hex Editor) to get the hex representation of the Euro symbol and it gives me the value as 80. Another site: http://www.string-functions.com/string-hex.aspx does the same. I am not able to understand why the hex representation is 80 instead of 0x20AC. This 0X80 gives 128 in decimal and if I use Alt+0128 it actually produces the Euro symbol. Could somebody throw some light on what could be the logic behind this conversion from string to hex conversion ? Thanks

  • java-COM interop: Implement COM interface in Java

    - by mdma
    How can I implement a vtable COM interface in java? In the old days, I'd use the Microsft JVM, which had built in java-COM interop. What's the equivalent for a modern JRE? Answers to a similar SO question proposed JACOB. I've looked at JACOB, but that is based on IDispatch, and is aimed at controlling Automation serers. The COM interfaces I need are custom vtable (extend IUnknown), e.g. IPersistStream, IOleWindow, IContextMenu etc. For my use case, I could implement all the COM specifics in JNI, and have the JNI layer call corresponding interfaces in java. But I'm hoping for a less painful solution. It's for an open source project, so open source alternatives are preferred.

  • Problem creating ObjectContext from different project inside solution.

    - by Levelbit
    I have two projects in my Solution. One implements my business logic and has defined entity model of entity framework. When I want to work with classes defined within this project from another project I have some problems in runtime. Actually, the most concerning thing is why I can not instantiate my, so called, TicketEntities(ObjectContext) object from other projects? when I catch following exception: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. I found out it's brake at: public partial class TicketEntities : global::System.Data.Objects.ObjectContext { public TicketEntities() : base("name=TicketEntities", "TicketEntities") { this.OnContextCreated(); } with exception: Unable to load the specified metadata resource. Just to remind you everthing works fine from orginal project.

  • jquery validate plugin: add a custom method

    - by pixeline
    I need some guidance on how to add a validation method to the jquery validate plugin. I've gathered that i need to use the plugin's addMethod() function, but how exactly to have it do what i need... Here i am! My form 's first question is a radio input choice. Each radio input, if selected, shows a sub-question of several checkboxes. What i would like my validation to do is: - make sure one radio input is selected - make sure at least one checkbox pertaining to the radio input is selected. Basically, out of the validate plugin's own logic, i would count the selector's length, and if there isn't any, return the error message. Something like this: var weekSelected = ($('input.seasonSelector:checked input.weekSelector:checked',form).length > 0); if(!weekSelected){ return 'Please select a week inside that season'; } How to turn that into a validate plugin method ?

  • UI-Automation cmdlet not finding the control

    - by sc_ray
    Hi, I am trying to test a WPF application using the UI-Automation framework that MSFT provides. There were a few powershell scripts written that invoked the cmdlets created to manipulate the visual controls of the application. There is a DropDown within my application that has an entry 'DropDownEntry'. In my cmdlet, I am trying to do something as follows: AutomationElement getItem = DropDown.FindFirst(TreeScope.Descendants, new AndCondition( new PropertyCondition(AutomationElement.ControlTypeProperty,ControlType.ListItem), new PropertyCondition(AutomationElement.NameProperty, "DropDownEntry",PropertyConditionFlags.IgnoreCase))); The above given snippet returns 'null' upon execution which essentially means that the above given logic was unable to find my dropdown entry. Can somebody tell me why this might be happening? I checked the name of my control and the values. Everything seems to be in order. I am not sure why this would be happening. Any help would be much appreciated. Thanks

  • What way to use the CGContext to draw is suitable?

    - by Tattat
    I know that the CGContext cannot call it to draw directly, and it needs to fill the drawing logic in the drawInContext, and call the CGContext to draw using "setNeedsDisplay", so, I designed a cmd to execute, but it cause some problems... like this : http://stackoverflow.com/questions/2617827/why-i-cant-draw-in-a-loop-using-uiview-in-iphone I think the CGContext is very different from my previous programming experience....(I used HTML5 canvas, that allow me add more details, after I draw, so do the Java Swing) Actually, I want to know what is the suitable to implement these kind of thing in Apples' programmer mind. Thz.

  • Sync Framework, Local Database Cache, and my DAL

    - by Refracted Paladin
    I am creating a WPF app that needs to allow users to work in a temporary disconnected state and I plan to use a Local Database Cache. My question's are about my data access layer. Do you typically create the whole DAL to point at the Cache or both and create a switching mechanism? Is Entity's a good way to go for my DAL against the Cache? I am used to L2S but my understanding is that I can't use that against SQLCE, correct? Thanks! PS: Any good resources out there for using Sync, Linq, and WPF? Tutorials, videos, etc?

  • Using background-attachment:fixed in safari on the ipad

    - by chris_bcn
    I'm looking to recreate an effect similiar to the popular science app. Basically have one big background image and then have HTML/CSS layer on top of that. When the user scrolls the content, then background-position of the image should remain in place, and not scroll. Obviously in a 'regular' browser I would use background-attachment:fixed, but this doesn't seem to work on the ipad. I know position:fixed doesn't work as you might expect according to safari spec - but is there any way of achieving this?

  • how to make a universal iphone/ipad app programmatically, navigation controller for iphone and spli

    - by arash13
    I couldn't find a good answer anywhere. I am using a UINavigationController for my iphone app and everything is done 100% programmatically no xibs. So i am trying to port my app to ipad, i tried to use a UISplitViewController and link my existing tableView and etc.. Now, i am not sure where should i have the logic of my program separating the viewcontroller for iphone or ipad.. do i setup my main file to use a different appdelegate or i use a same appdelegae and have the condition set up there ? now beside this, whenever i try to complile my app on the simulator it does not recognize the uisplitview and even the condition in which i check if the class exists. can please someone put me in the right direction.. and remember i am not using xibs?

  • Configure Active Relying Party STS to Trust Multiple Identity Provider STSes

    - by CodeChef
    I am struggling with the configuration for the scenario below. I have a custom WCF/WIF STS (RP-STS) that provides security tokens to my WCF services RP-STS is an "Active" STS RP-STS acts as a claims transformation STS RP-STS trusts tokens from many customer-specific identity provider STSes (IdP-STS) When a WCF Client connects to a service it should authenticate with it's local IdP-STS The reading that I've done describes this as Home Realm Discovery. HRD is usually described within the context of web applications and Passive STSes. My questions is, for my situation, does the logic for choosing an IdP-STS endpoint belong in the RP-STS or the WCF Client application? I thought it belonged in the RP-STS, but I cannot figure out the configuration to make this happen. RP-STS has a single endpoint, but I cannot figure out how to add more than one trusted issuer per endpoint. Any guidance on this would be very appreciated (I'm out of useful keywords to Google.) Also, if I'm way off please offer alternative approaches. Thanks!

  • Data validation: fail fast, fail early vs. complete validation

    - by Vivin Paliath
    Regarding data validation, I've heard that the options are to "fail fast, fail early" or "complete validation". The first approach fails on the very first validation error, whereas the second one builds up a list of failures and presents it. I'm wondering about this in the context of both server-side and client-side data validation. Which method is appropriate in what context, and why? My personal preference for data-validation on the client-side is the second method which informs the user of all failing constraints. I'm not informed enough to have an opinion about the server-side, although I would imagine it depends on the business logic involved.

  • MTU mismatch between GetIfEntry and netsh

    - by ChrisJ
    I'm working on pseudo-transport layer software that runs over UDP, providing reliable connection-oriented transmission, as an alternative to TCP. In order to maximize network efficiency, we query the MTU of the "best" network adapter upon initialization. MIB_IFROW row = {0}; row.dwIndex = dwBestIfIndex; dwRes = GetIfEntry(&row); Searching online I found that you can use the following netsh commands to query for this same value, from a command prompt (not a C++ API) netsh interface ipv4 show interfaces netsh interface ipv4 show subinterfaces The troubling issue is that while row.dwMtu may be set to 1500, snooping the network traffic on the sending laptop shows that our packets are fragmented into 1300 byte packets. netsh also reports that the MTU is 1300. Clearly the value reported by netsh command is the actual used values. Anyone know what API I can call to get the same values as netsh?

  • Speed Difference between native OLE DB and ADO.NET

    - by weijiajun
    I'm looking for suggestions as well as any benchmarks or observations people have. We are looking to rewrite our data access layer and are trying to decide between native C++ OLEDB or ADO.NET for connecting with databases. Currently we are specifically targeting Oracle which would mean we would use the Oracle OLE DB provider and the ODP.NET. Requirements: 1. All applications will be in managed code so using native C++ OLEDB would require C++/CLI to work (no PInvoke way to slow). 2. Application must work with multiple databases in the future, currently just targeting Oracle specifically. Question: 1. Would it be more performant to use ADO.NET to accomplish this or use native C++ OLE DB wrapped in a Managed C++ interface for managed code to access? Any ideas, or help or places to look on the web would be greatly appreciated.

  • "Authorize" attribute and 403 error page

    - by zerkms
    [Authorize] property is nice and handy MS invention, and I hope it can solve the issues I have now To be more specific: When current client isn't authenticated - [Authorize] redirects from secured action to logon page and after logon was successfull - brings user back, this is good. But when current cilent already authenticated but not authorized to run specific action - all I need is to just display my general 403 page. Is it possible without moving authorization logic within controller's body? UPD: The behavior I need in should be semantically equals to this sketch: public ActionResult DoWork() { if (!NotAuthorized()) { return RedirectToAction("403"); } return View(); } so - there should no any redirect and url should be stay the same, but contents of the page should be replaced with 403-page

  • How can I tell when a UIWebView has finished drawing to a context?

    - by phopkins
    In my code I'm trying to show a UIWebView as a page is loading, and then, when it's done, capture an image from the web view to cache and display later (so I don't have to reload and render the web page). I have something along the lines of: CGContextRef context = CGBitmapContextCreate(…); [[webView layer] renderInContext:context]; CGImageRef imageRef = CGBitmapContextCreateImage(context); UIImage *image = [UIImage imageWithCGImage:imageRef]; The problem I'm running into is that, due to UIWebView's tiling, sometimes only half of the page is rendered to the context by the time I capture the image. Is there a way to detect or block on UIWebView's background rendering thread so that I can get the image only after all of the rendering has finished?

  • Notify DataTemplateSelector about the change

    - by Tigran
    I use DataTemplateSelector for ListView column headers template selection. ListView itself is in DataTemplate and ends up in a few tabs. So, in practice, I have same DataTemplate (so ListView too) shared between more TabItems. This means that if I select tab {A} and set XDataTemplate on ListView column {AColumn}, if I switch the tab, lets say to tab {B}, on {B}'s ListView (that is always the same one) column {AColumn} we will see the same XDataTemplate, because we share same UI data. So I created data layer where I hold relational information about {Tab} <- {ListView:Column} <- {HeaderContent}, which actually reads DatatemplateSelector in order correctly update UI on user screen. What I need is to notify to DataTemplateSelector to update current view in the moment that I need. How can I achieve that goal? Thank you.
