• Accessing protected REST endpoint with JQuery

  - by Andy

  I have a site where members login to their account (FormsAuth). I would like to set up a RESTful service that I can access using jQuery. I would like to protect these services using the same FormsAuth. How would a third-party site be able to access these services? They would need to pass in the Principal/Identity to the service, right? I've only seen examples of Basic Authentication (which Twitter uses and jQuery supports). I'm very new to WCT/REST, so not sure how this should be done.

• How to get the last key pressed on Mac ?

  - by Dheeraj

  Hi All, I'm writing a plugin for an application. I cannot derive from NSApplication as it is a third party application. I can get the callback in my plugin when any key is pressed. But I will not know what key is pressed. So is there any call in Cocoa to find the last key pressed when I get the callback? I only have NSView object. Any ideas will help me a lot. Thanks, Dheeraj.

• Office Automation Libraries

  - by Ian

  Some time ago I posted about a question about reading Excel files as a server process, to get around the tighter restrictions Microsoft have been applying on Office Automation. I now need to extend this, by finding methods/libraries to read other sorts of Office files in an automated way on a server. The applications I'm interested in are Word, Powerpoint, Project and to a lesser extent Word and Visio. I need to be able to support 97-2003 office files, and the newer open xml formats (e.g. xlsx, docx) at a very least. With regards to Word integration, I also need to be able to handle writing/reading RTF text. If anyone has any suggestions I'd be pleased to hear them. Thanks

• pySerial writes to Arduino Uno get buffered

  - by Bhaktavatsalam Nallanthighal

  I have a Python script that writes short messages to the serial port on my Arduino Uno board using pySerial. There is a loop and depending on some conditions, multiple writes can happen within a loop, something like this: while True: #Conditions block 1 if <CONDITION1>: serial.writelines("INIT") elif <CONDITION2>: serial.writelines("NEW") ... #Conditions block 2 if <CONDITION1>: # Fetch something from the Internet serial.writelines("CHECK") elif <CONDITION2>: # Fetch something from the Internet serial.writelines("STOP") ... But, when my Arduino board receives this it receives the first message as INIT, but the second one is being read as INITSTOP or INITCHECK and third one gets concatenated to the previous messages. My arduino program checks for specific message in this way: if(msg.equals("CHECK")) { // Do something } else if(msg.equals("INIT")) { // Do Something else } Can anyone guide me on this? BTW, I don't think the problem is with the Arduino as it works perfectly when I test it with the Serial Monitor available with the IDE. I've tried adding sleeps of upto 10 seconds before every write, but that did not work out.

• What are some of the practical cons to using ASMX webservices?

  - by Earlz

  Hello, at my workplace we are about to start a big project. My boss (a programmer, this is a startup) wishes to use ASMX webservices for this purpose. I do not want to start off a new program using deprecated technology and would like to show him this. I dislike WCF at this moment because it has such an extreme learning curve, but I'd rather learn it than use an unsupported technology. The problem I'm having is that I can not find any practical list of cons and downfalls when compared to WCF so that I can convince my boss to not use them. And saying "it's not as powerful" is not an adequate explanation. What exactly can it not do that we may need it to do for a webservice that is not meant to be shared externally? (as in, we don't support third-parties using our webservices unless they are using one of our clients. )

• Is it possible to use JSONP on the server?

  - by Denis Hoctor

  Hi all, I'm stuck on a clients host that has medium trust setup which blocks cross domain requests and need data from a 3rd party domain. I now have the option to use JSONP. I've used JSONP from the client with jQuery to get around the browsers cross domain security and I've used HttpWebRequest in ASP.Net 3.5. Is it possible to use JSON on the server and if so how? I don't think it is, but worth asking seeing as I already have this app written server side.... Thanks, Denis

• Will this safely delete my record?

  - by Sergio Tapia

  I hate these three tables that. Two tables have a many to many relationship and as such it generates a third table. I'm using Linq-to-SQL and in the .dbml file I've dragged all the folder there to the graphic surface. Here is the method I'm using to delete an Area safely. Remember that documents are associated to an Area, so I can't just delete it and leave documents hanging. ScansDataContext db = new ScansDataContext(); /// <summary> /// Deletes an Area object from the database along with all associations in the database. /// </summary> /// <param name="area">Area object to save</param> public void Delete(Area area) { db.DocumentAreaRelations.DeleteAllOnSubmit(area.DocumentAreaRelations); db.Areas.DeleteOnSubmit(area); db.SubmitChanges(System.Data.Linq.ConflictMode.FailOnFirstConflict); }

• What software development process do you use and how do you implement it?

  - by clyfe

  Post only what you do use not what you would like to use, so we can see what is the most popular in real life. I am interested only in theese issues: Project Model (waterfall, agile...) How are requirements gathered (and stored)? Revision control - what software, what workflow Build automation, what software, where does it fit ? How is the testing done ? How is the documentation done ? How is the quality assurance done ? Please provide short objective answers, don't speak from the books. EXAMPLE: In my company we are a small team of 5 people and we develop webapps using ruby. agile PM cucumber requirements git SCM - Integration Manager Workflow integrity CI rspec automated tests the project lead creats the documentation skeleton then it is filled by the developers ensure quality by peer reviewing code and manual peer-testing

• Why can't I get Python's urlopen() method to work?

• Django: query with ManyToManyField count?

  - by AP257

  In Django, how do I construct a COUNT query for a ManyToManyField? My models are as follows, and I want to get all the people whose name starts with A and who are the lord or overlord of at least one Place, and order the results by name. class Manor(models.Model): lord = models.ManyToManyField(Person, null=True, related_name="lord") overlord = models.ManyToManyField(Person, null=True, related_name="overlord") class Person(models.Model): name = models.CharField(max_length=100) So my query should look something like this... but how do I construct the third line? people = Person.objects.filter( Q(name__istartswith='a'), Q(lord.count > 0) | Q(overlord.count > 0) # pseudocode ).order_by('name'))

• How to catch printf from a dll?

  - by Xarx

  I've got a C++ console application that uses a third-party dll (jvm.dll, indirectly) that uses printf to print various error messages (Java stacktrace). I need to catch these stacktraces to a string in order to process them further, or at least to see them printed on the console. The thing is that I see the stacktrace only when debugging my application in VisualStudio (VS 2010). When I run my application in the "normal way", i.e. from the command line, nothing is printed on the console. So VS is able to somehow interfere the java output and display it. I need to be able to do the same thing. I've already tried freopen(), but without success. Also, I've found this question on the same problem, but without a clear answer.

• How do you send email invites to people who have been invited by users of your website?

  - by Arpit Rai

  We've developed a web application where people can sign-up on our website to make use of our service. We have a functionality that allows users to send invites to their friends by looking up their contacts on Gmail, Yahoo Mail etc. My question is - do we have to use a 3rd party email management software like a MailChimp or SendGrid to send such emails or should we send them directly? If we send the emails directly and if the recipients start marking those emails as spam, isn't there a very high chance that we might get banned by Gmail, Yahoo etc.?

• Equality Comparison with Multiple Instances/IEqualityComparer problems in LINQ

  - by Stacey

  This is similar to my last question; but from a different angle. http://stackoverflow.com/questions/2792393/see-if-item-exists-once-in-enumerable-linq Given the following set of items, and lists containing them... Item 1 Item 2 Item 3 Item 4 Item 5 class Item { string Name { get; set; } } List<Item> available = new List<Item>() { Item 1 Item 1 Item 2 Item 3 Item 5 } List<Item> selected = new List<Item>() { Item 1 Item 2 Item 3 } I need to make a third List that has everything from "available", except what is in "selected". However 'Item 1' is in 'available' twice, but only in 'selected' once. Since they are instances of the same item, I am having trouble figuring out the appropriate logic to accomodate this. The final array should look like... List<Item> selectable = new List<Item>() { Item 1 Item5 }

• Java - binary compatibility of abstract class & subclasses

  - by thSoft

  In Java, I define an abstract class with both concrete and abstract methods in it, and it has to be subclassed independently by third-party developers. Just to be sure: are there any changes I could make to the abstract class that are source compatible with their classes but not binary compatible? In other words: after they have compiled their subclasses, could I change the abstract class - apart from e.g. adding an abstract method to it or removing a protected method from it that is called by subclasses, which are of course source incompatible - in a way that could force them to recompile their subclasses?

• iphone poll application to sync with myspace or facebook poll.

  - by Zach

  Hi, We are developing an iphone application, which requires us to add polling(survey) functionality in the app. We also have same poll in either MySpace or Facebook. We have to sync the polling data to our iphone application. How can we achieve this? We have found some third party polling service provider like Zoomerang, Poll Daddy polls, etc., but they don't have supporting API for iphone application or at least one we are not aware of. If anyone can shed light on this on how to proceed with this, it will be really very helpful. Thanks in advance. Zach.

• Wpf- Is there any way to disable some of the default hotkeys in a RichTextBox?

  - by Justin

  I have several keybindings in my text editing application that no longer work now that I have switched from using a regular textbox to using a richtextbox. This is because the wpf richtextbox has several default hokeys such as "Ctrl+1", "Ctrl+2", and "Ctrl+5". My keybindings are defined in a view that contains the view that the richtextbox is in. I can't move the keybindings to the richtextbox; Is there any fix for this problem? Other than using a third-party control or creating my own richtextbox from textboxbase.

• Hudson CI project doesn't run NetBeans JUnit tests of dependent projects

  - by Liron Yahdav

  I have a set of NetBeans java projects with dependencies between them. I added the project at the top of the dependency tree to Hudson for continuous integration. Everything works fine, except that the unit tests of dependent projects don't get run by Hudson. This is because the ant scripts that NetBeans creates has dependent projects setup to run the "jar" target and not a target that also runs the unit tests. I could add ant build steps for each dependent project in Hudson to run the unit tests, but I was hoping there's a simpler solution.

• DWR and Jquery into spring MVC 2.5

  - by Mark Estrada

  Hi, From my shallow reading, Spring MVC does not support jquery directly. It does enable integration with DWR framework. From my understanding of DWR, it is an ajax framework that allows you to call javas methods from javascript. Can I use both in my application? With Jquery handling most of the javascript code and client side interaction and DWR making the ajax calls? I am leaning towards learning jquery but there is no out of the box support for it in spring 2.5.

• Graphics.FromHwnd(IntPtr.Zero) returns null, why?

  - by Martin Moser

  I'm currently investigating a problem with a 3rd party component (DevExpress) in my application. My issue is quite similar to this one DevExpress KB article. I get the same exception with more less the same stacktrace. So I used .NET Reflector to find out, what may be null in this scenario, and the only object which is a candiate to be null is Graphics. This is created with Graphics.FromHwnd(IntPtr.Zero). Because I don't have a broad knowledge about GDI, I would like to know if somebody can tell me possible scenarios when this may return null... I tried to reproduce it in a scenario where windows is out of GDI handle's, but then I'm getting a "out of handles" - exception at least once, which is not the case in the issue I'm investigating tia, Martin

• How do you configure IIS5 advanced settings from command line?

  - by Jason

  I am trying to automate some of the build process for my asp.net apps by creating the virtual directories it needs and setting all their settings in a batch file. So far I have been able to figure out how to create virtual directories, but how to do you configure them beyond that? For example I need to be able to set them as an application, set the default document, change framework version, turn on integrated authentication, etc. Does anyone know of any scripts that can do all this without a third party utility? Does the adsutil.vbs admin script do any of this?

• How to find all the file handles by a process programmatically?

  - by kumar

  I have a process "x" which uses "system" C function to start ntpd daemon. I observed that ntpd are passed the open file descriptors of "x". ntpd holds on to the file descriptors even after original file is deleted. for ex: Some log files used by "x" are rotated out after sometime, but "ntpd" has file handle opened for these deleted files. Will it cause any problem? Alternatively I thought of setting "FD_CLOEXEC" flag for all the file descriptors before calling "system" function. But as we are running as an extension library to third process "x"( "x" loads our library based on some condition), there is no easy way to know about all the file descriptors process has opened. One way is to read /proc//fd and set "FD_CLOEXEC" for each file handle and reset it back after "system" function returns. I'm using Linux 2.16. Is there any other easy way to find all the file handlers? Thanks,

• How to organize asp.net mvc project (using entity framework) and a corresponding database project?

  - by Bernie

  I recently switched to vs2010 and am experimenting with asp.net MVC2. I am building a simple website and use the entity framework to design the data model. From the .edmx file, I generate the database tables. After a few iterations, I decided that it would be nice to have version control of the database schema as well, and therefore I added a database project into which I imported the script that is generated from the datamodel. As a result, I have to generate the sql every time that I change the model and redo the import. The database project automatically updates the database. Although the manual steps to generate the sql and the import are annoying, this works pretty well, until I wanted to add the standard tables for user accounts/authorization etc. I can use the framework tools to add the necessary tables, views etc. to the database, but as I do not want to have them in the .edmx model I end up with a third manual step. Is anybody facing similar issues?
