• Seeking enlightenment - global variables in AppEngine (aeoid.get_current_user())

  - by jerd

  Hello This may be a 'Python Web Programming 101' question, but I'm confused about some code in the aeoid project (http://github.com/Arachnid/aeoid). here's the code: _current_user = None def get_current_user(): """Returns the currently logged in user, or None if no user is logged in.""" global _current_user if not _current_user and 'aeoid.user' in os.environ: _current_user = User(None, _from_model_key=os.environ['aeoid.user']) return _current_user But my understanding was that global variables were, ehm, global! And so different requests from different users could (potentially) access and update the same value, hence the need for sessions, in order to store per-user, non-global variables. So, in the code above, what prevents one request from believing the current user is the user set by another request? Sorry if this is basic, it's just not how i thought things worked. Thanks

• Best way to unit-test WCF REST/SOAP service while dynamically generating stubs

  - by James Black

  I have a webservice written with WCF 4.0 that exposes REST and SOAP functions, and I want to set up my unit tests so that as I work on my web services I can quickly test by having the test framework start up the service, outside of IIS, and then do the tests. I want it to be dynamically generated as I am not certain what the interface will look like, and it is easier to not worry about having to generate the stubs before I start the tests. But, I couldn't get Groovy to work with my web service, so I am curious if Iron Python or Iron Ruby would work well for this, or is there another .NET language that may work well for this.

• asp.net mvc controller actions testing

  - by Imran

  I was just wondering how others are going about testing controller actions in asp.net mvc? Most of my dependencies are injected in to my controllers so there is a not a huge amount of logic in the action methods but there may be some conditional logic for example which I think is unavoidable. In the past I have written tests for these action methods, mocked the dependencies and tested the results. I have found this is very brittle and a real PITA to maintain. Having 'Expect' and 'Stub' methods everywhere breaks very easily but I don't see any other way of testing controller actions. I actually think it might be easier to test some of these manually! Anyone have any suggestions? Perhaps I am missing something here? Thanks Imran

• FBA and audience targeting in sharepoint 2007

  - by intangible02

  I want to use audience targeting feature for webpart with FBA. I tried to add FBA user directly in sharepoint group or added the user to a asp.net role and then added the role to sharepoint group, but both failed. My observation is that all FBA users can see the webpart content no matter whether they are specified in audience targeting or not. After googling it, I found there are three different conclusion about this, FBA cannot be used with audience targeting FBA can be used with audience targeting FBA can be used with audience targeting if the FBA user is added directly to sharepoint group May I know which is the correct explanation? Where can I find official Microsoft documentation regarding to this problem?

• ASP.NET MVC 2 validation using DTOs instead of domain entities

  - by Kevin Pang

  I'm struggling to mesh two best practices together: Using DataAnnotations + ModelBinding for validation in ASP.NET MVC 2 Using DTOs instead of domain entities when passing data via the ViewModel If I want to pass over DTOs instead of domain entities, then leveraging DataAnnotations + ModelBinding for validation would require me to specify validation attributes on my DTO classes. This results in a lot of duplicated work since multiple DTOs may hold overlapping fields with the same validation restrictions. This means that any time I change a validation rule in my domain, I have to go find all DTOs that correspond with that value and update their validation attributes.

• safely lock a file then move? windows

  - by acidzombie24

  I have a file and need to ensure it exist before inserting a row into the db. After i insert i need to use the PK as part of the filename and move it into another location. How do i check if it exist then lock it so it cant be deleted until i can insert into the db then proceed to move the file without it being deleted upon releasing the lock? also the file may be in use. I am thinking of copying the file into a safe location then moving that file away. In this case i need to copy a file that is being used for reading. How can i do the above steps safely? Using .NET

• Is there a performance advantage in using a 64bit version of openCV+Emgu instead of 32bit?

  - by Jelly Amma

  Hello, I am developing an application that processes images captured in real time by a Point Grey camera (http://www.ptgrey.com/). The Point Grey SDK is a .net wrapper and can be either 32bit or 64bit. Then to process the captured images, I'm using a wrapper for openCV called Emgu CV (http://www.emgu.com/) that comes in both 32bit or 64bit flavors as well. Now, being on Vista64 I went for the 64bit versions of FlyCapture (Point Grey's SDK) and Emgu CV (which includes openCV in its install) hoping to maximize performance. Recently I've been wanting to call my FlyCapture+Emgu DLL code from XNA, which unfortunately only exists in 32bit, and I realize that I may have to reinstall all those components in 32bit as I don't really want to go through IPC, remoting, etc. Apart from the obvious limit to memory space inherent to 32bit, is there also a performance loss I should be expecting? How dramatic would that be and why ? Thanks in advance for any advice or explanation.

• MediaElement.Position behaviour and Windows Phone 7 issue

  - by RoguePlanetoid

  I have a problem, I have written a simple Media Player for Windows Phone 7 and can Play, Stop and control the Volume of a Video (loaded from a URI) however when I try to set the position, this causes the application to freeze. I have used both these lines, but either does not work: Player.Position = new TimeSpan(0, 0, 0, 0, (int)Position.Value); Player.Position = TimeSpan.FromSeconds((int)(Position.Value)); I do have this event handler: void Player_MediaOpened(object sender, RoutedEventArgs e) { Position.Maximum = Player.NaturalDuration.TimeSpan.TotalMilliseconds; } And have tried using the Seconds value, casting to Ints etc, however everytime I try to set the Position, the app freezes. The video otherwise plays normally - anyone know what the problem may be here?

• Disposables, Using & Try/Catch Blocks

  - by Aren B

  Having a mental block today, need a hand verifying my logic isn't fubar'ed. Traditionally I would do file i/o similar to this: FileStream fs = null; // So it's visible in the finally block try { fs = File.Open("Foo.txt", FileMode.Open); /// Do Stuff } catch(IOException) { /// Handle Stuff } finally { if (fs != null) fs.Close(); } However, this isn't very elegant. Ideally I'd like to use the using block to dispose of the filestream when I'm done, however I am unsure about the synergy between using and try/catch. This is how i'd like to implement the above: try { using(FileStream fs = File.Open("Foo.txt", FileMode.Open)) { /// Do Stuff } } catch(Exception) { /// Handle Stuff } However, I'm worried that a premature exit (via thrown exception) from within the using block may not allow the using block to complete execution and clean up it's object. Am I just paranoid, or will this actually work the way I intend it to?

• dynamic insert php mysql and preformance

  - by Ross

  I have a folder/array of images, it may be 1, maximum of 12. What I need to do is dynamically add them so the images are added to an images table. At the moment I have $directory = "portfolio_images/$id/Thumbs/"; $images = glob("" . $directory . "*.jpg"); for ( $i= 0; $i <= count($images); $i += 1) { mysql_query("INSERT INTO project_images (image_name, project_id)VALUES ('$images[0]', '$id')") or die(mysql_error()); } this is fine but it does not feel right, how is this for performance? Is there a better way? The maximum number of images is only ever going to be 12. Thanks, Ross

• NHibernate Session Management Advice

  - by Hugusta

  I need some advice on NHibernate Session Management for a C# WinForms application. I am currently porting an application to use NHibernate. I am also employing a UnitOfWork pattern as described in the link below; http://nhforge.org/wikis/patternsandpractices/nhibernate-and-the-unit-of-work-pattern.aspx My question relates to Sessions. Can you only have one session running per thread at all times? I have a scenario in which a Session (UnitOfWork) may be open for a form shown by the application but the user opens another form (i.e. Tools - Options) which I would like to have its own UnitOfWork. Clearly in this instance it would make more sense to open another Session for the "Tools - Options" form and not use the currently open session for the underlying form. Can we have a Dictionary of Sessions on the one thread? Any advice on session management is appreciated.

• Problem passing json into jquery graph(flot)

  - by Adam McMahon

  I trying to retrieve some json to pass into a flot graph. I know that json is right because I hard coded it to check, but I'm pretty sure that I'm not passing right because It's not showing up. Here's the javascript: var total = $.ajax({ type: "POST", async: false, url: "../api/?key=xxx&api=report&crud=return_months&format=json" }).responseText; //var total = $.evalJSON(total); var plot = $.plot($("#placeholder"),total); here's the json: [ { data: [[1,12], [2,43], [3,10], [4,17], ], label: "E-File"}, { data: [[1,25], [2,35], [3,3], [4,5], ], label: "Bank Products" }, { data: [[1,41], [2,87], [3,30], [4,29], ], label: "All Returns" } ], {series: {lines: { show: true },points: { show: true }}, grid: { hoverable: true, clickable: true }, yaxis: { min: 0, max: 100 }, xaxis: { ticks: [[1,"January"],[2,"February"],[3,"March"],[4,"April"],[5,"May"],[6,"June"],[7,"July"],[8,"August"],[9,"September"],[10,"October"],[11,"November"],[12,"December"]] }}

• use of EntityManagerFactory causing duplicate primary key exceptions

  - by bradd

  Hey guys, my goal is create an EntityManager using properties dependent on which database is in use. I've seen something like this done in all my Google searches(I made the code more basic for the purpose of this question): @PersistenceUnit private EntityManagerFactory emf; private EntityManager em; private Properties props; @PostConstruct public void createEntityManager(){ //if oracle set oracle properties else set postgres properties emf = Persistence.createEntityManagerFactory("app-x"); em = emf.createEntityManager(props); } This works and I can load Oracle or Postgres properties successfully and I can Select from either database. HOWEVER, I am running into issues when doing INSERT statements. Whenever an INSERT is done I get a duplicate primary key exception.. every time! Can anyone shed some light on why this may be happening? Thanks -Brad

• MobileMe Connection - Cocoa

  - by David Schiefer

  Hi, I need to send a file to MobileMe via Cocoa. I stumbled across a .Mac framework from Apple but it hasn't been updated in years, so I don't want to use it due to possible compatibility problems it may cause. I think that the MobileMe.framework is private, so I don't think I can use it. What kind of alternatives are there available for me so that I can upload the file to MobileMe? I've also been looking into WebDav frameworks (since MobileMe is WebDav based), but I didn't find anything useful either. Thanks!

• Three ways to upload/post/convert iMovie to YouTube

  - by user351686

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

• How to determine MS Access field size via OleDb

  - by Andy

  The existing application is in C#. During startup the application calls a virtual method to make changes to the database (for example a new revision may need to calculate a new field or something). An open OleDb connection is passed into the method. I need to change a field width. The ALTER TABLE statement is working fine. But I would like to avoid executing the ALTER TABLE statement if the field is already the appropriate size. Is there a way to determine the size of an MS Access field using the same OleDb connection?

• How do I change my iPhone App binary filename

  - by Kamchatka

  I get the following error when I try to upload the application on iTunes Connect: "Binary file names cannot contain a space. Please rename your binary file and try again." If I try to Validate the Application in XCode, I get: "My Application.ipa: filename may not contain whitespace" So I guess I have to find a way to rename this .ipa file. I don't want to change my product name which has to stay "My Application". How can I do that? Thanks!

• Core Animation not working on Leopard, working on Snow Leopard

  - by Nick Paulson

  Hi, I animate NSImageViews using its animator proxy. While testing my application on Snow Leopard, everything works as expected. However, on Leopard, none of the animations are functioning. In addition, NSImageViews don't seem to take into effect the alphaValue I set on them, whether through the animator proxy or not. The only way I can get them to disappear is by setting their image to nil. What is weird is that this all works fine in Snow Leopard, but does not work on Leopard 10.5.8. Any idea on why this may be occurring?

• About "If.." in Scheme (plt-scheme)

  - by Amit

  I had a pretty simple requirement in my Scheme program to execute more than one statement, in the true condition of a 'if'. . So I write my code, something like this: (if (= 1 1) ((expression1) (expression2)) ; these 2 expressions are to be executed when the condition is true (expression3) ) Obviously, the above doesn't work, since I have unintentionally created a # procedure with # arguments. So, to get my work done, I simply put the above expressions in a new function and call it from there, in place of the expression1, expression2. It works. So, my point here is: is there any other conditional construct which may support my requirement here?

• FileInfo..ctor(string fileName) throwing exception: bug in SL 4.0 or .NET 4.0?

  - by Duncan Bayne

  The following test case passes in .NET 4.0: var fiT = new FileInfo("myhappyfilename"); Assert.IsNotNull(fiT); ... but fails in Silverlight 4.0 with the following error: System.ArgumentNullException: Value cannot be null. Parameter name: format at System.String.Format(IFormatProvider provider, String format, Object[] args) at System.Environment.GetResourceString(String key, Object[] values) at System.IO.FileSecurityState.EnsureState() at System.IO.FileInfo.Init(String fileName, Boolean checkHost) at System.IO.FileInfo..ctor(String fileName) Either the failure is a bug in SL 4.0, or the non-failure is a bug in .NET 4.0. Anyone know which it is? (For the record, I'm running SL 4.0 on VS 2010 RC, which may be contributing to the problem).

• Enumerations and String values in ASP.NET

  - by Jason

  I'm looking for some best practice advice on enumerations and retrieving an associated string value. Given this: public enum SerialKillers { TedBundy, EdGein, AlbertFish, GeorgeBush } What is the best way to get a related string value of the name? Eg. "Ted Bundy", given that the string value may not match the representation in the enumeration. eg "George W Bush" My current thinking is function accepting an enum and returning a string, but would that not mean hard coding the string values (which I prefer not to do)? Is using a resources file where the string can be retrieved via the enumeration too heavy handed? Should I accept the fact I am going to Hell for victimising Ted Bundy by associating him with George Bush?

• Logic / Probability Question: Picking from a bag

  - by Rosarch

  I'm coding a board game where there is a bag of possible pieces. Each turn, players remove randomly selected pieces from the bag according to certain rules. For my implementation, it may be easier to divide up the bag initially into pools for one or more players. These pools would be randomly selected, but now different players would be picking from different bags. Is this any different? If one player's bag ran out, more would be randomly shuffled into it from the general stockpile.

• Jdeveloper vs java/j2ee/js+extjs ?

  - by ssgam

  Hi All, i am new to the web development environment, having came from a unix/c environment. i've been recently asked to create a web app, which i thought would require postgresql, java/j2ee, and javascript for the client interface. as i had wanted a nicer gui, i've been reading up on extjs, which looks really nice to me. a colleague mentioned that the time needed time needed to learn all these various pieces is time consuming, and Jdeveloper seems to provide most of what we'd need (i was shown a demo, which appears to be able to generate some nice web interfaces). what are the pros and cons with the different approaches ? some i can think of: - jdeveloper is an integrated ide, which creates UI easily, tightly integrated with database. (pro) - jdeveloper will be heavier? (con) - wizard generated code may be harder to refactor ? (con) - java/j2ee/js+extjs needs to develop things from ground up (con) thanks in advance for sharing your experiences and thoughts ... sam
