• UITableView and UITableCellView, how does this work with core plot ?

  - by Luc

  Hello, I'm very new to iPhone programming, and I'm currently following tutos to understand the whole thing. I've been able to do what I needed (retrive data from a JSON http server, parse them with YAJL and plot the data in core plot). I have done this in a "simple" view where I have added a UILayerHostingView as requested by core-plot. I am now trying to follow this tuto: http://blogs.remobjects.com/blogs/mh/2010/01/26/p973 but I am missing the first part regarding the views... My understanding is that I need to create a view with a UITableView first. Then add a UITableCellView to make the first cell be able to contain the graph ? Is this right ? Where does the method "(id)initWithStyle:(UITableViewCellStyle)style" come from ? For my needs, only the first cell needs to contain a graph, I will put some other info in the other cells. As for now, I have created a new GraphListViewController, in the corresponding view I have added a listview but I do not see any auto generated methods regading cell customisation ? Do I need to implements DataSource in this controller and manually add some customisation methods ? Do I need to add a UITagbleViewCell to this UITableViewTable within IB ? Hope I am not getting to confusing... Thanks a lot for your help, Best Regards, Luc

• What issues to consider when rolling your own data-backend for Silverlight / AJAX on non-ASP.NET ser

  - by Edward Tanguay

  I have read-only Silverlight and AJAX apps which read static text and XML files from a PHP/Apache server, which works very nicely with features such as asynchronous loading, lazy-loading only what I need for each page, loading in the background, developed a little query language to get a PHP script to create custom XML files etc. it's pragmatic read-only REST, and all works fast and fine for read-only sites. Now I want to also add the ability to write data from these apps to a database on the same PHP/Apache server. For those of you who have built similar data-access layers, what do I need to consider while building this, especially regarding security so that not just any client can write and alter my database, e.g.: check HTTP_USER_AGENT for security check REMOTE_ADDR for security require a special code for security, perhaps a list of TAN codes (such as banks use for online transactions) each which can only be used once, both the client and server have these I wonder if there is some kind of standard REST query I should lean on for e.g. building SQL-like statements in the URL parameters, e.g. http://www.thedatalayersite.com/query?insertinto=customers&... Any thoughts, notes from experience, ideas, gotchas, especially ideas on tightening down security in this endeavor would be helpful.

• ASP.NET Model Binder and base type

  - by user137348

  My model inherits from an interface: public interface IGrid { ISearchExpression Search { get; set; } . . } public interface ISearchExpression { IRelationPredicateBucket Get(); } The model: public class Project : IGrid { public ISearchExpression Search { get; set; } public Project() { this.Search = new ProjectSearch(); } } The ProjectSearch: public class ProjectSearch: ISearchExpression { public string Name { get; set; } public string Number { get; set; } public IRelationPredicateBucket Get() {...} } And the strong typed partialview in the main view: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ProjectSearch>" %> <%= Html.TextBoxFor(x=>x.Name)%> <%= Html.TextBoxFor(x => x.Number)%> .... When I submit the form, the Search property don't get bound properly. Everything is empty.The action takes an argument of ProjectSearch type. Why the Search don't get bound as supposed ?

• How Can I Find Out *HOW* My Site Was Hacked? How Do I Find Site Vulnerabilities?

  - by Imageree

  One of my custom developed ASP.NET sites was hacked today: "Hacked By Swan (Please Stop Wars !.. )" It is using ASP.NET and SQL Server 2005 and IIS 6.0 and Windows 2003 server. I am not using Ajax and I think I am using stored procedures everywhere I am connecting to the database so I dont think it is SQL injection. I have now removed the write permission on the folders. How can I find out what they did to hack the site and what to do to prevent it from happening again? The server is up to date with all Windows updates. What they have done is uploading 6 files (index.asp, index.html, index.htm,...) to the main directory for the website. What log files should I upload? I have log files for IIS from this folder: c:\winnt\system32\LogFiles\W3SVC1. I am willing to show it to some of you but don't think it is good to post on the Internet. Anyone willing to take a look at it? I have already searched on Google but the only thing I find there are other sites that have been hacked - I haven't been able to see any discussion about it. I know this is not strictly related to programming but this is still an important thing for programmers and a lot of programmers have been hacked like this.

• On Windows 7: Same path but Explorer & Java see different files than Powershell

  - by Ukko

  Submitted for your approval, a story about a poor little java process trapped in the twilight zone... Before I throw up my hands and just say that the NTFS partition is borked is there any rational explanation of what I am seeing. I have a file with a path like this C:\Program Files\Company\product\config\file.xml I am reading this file after an upgrade and seeing something wonky. Eclipse and my Java app are still seeing the old version of this file while some other programs see the new version. The test that convinced my it was not my fat finger that caused the problem was this: In Explorer I entered the above path and Explorer displayed the old version of the file. Forcing Explorer to reload via Ctrl-F5 still yields the old version. This is the behavior I get in Java. Now in PowerShell I enter more "C:\Program Files\Company\product\config\file.xml" I cut and past the path from Explorer to make sure I am not screwing anything up and it shows me the new version of the file. So for the programming aspect of this, is there a cache or some system component that would be storing this stale reference. Am I responsible for checking or reseting that for some class of files. I can imagine somebody being "creative" in how xml files are processed to provide some bell or whistle. But it could be a case of just being borked. Any insights appreciated...Thanks!

• Windows Phone - OnNavigatingFrom - problem

  - by Martin Anderson

  I believe this is just a problem for me, due to my lack of programming ability. I am currently exploring transitions between page navigation with Windows Phone apps. I was originally using storyboards, and completed event handlers to have my pages animate on and off screen. These leads to the a problem when you want to navigate to many pages from one page, using the same transition. So I have started looking at OnNavigatedTo, and OnNavigatingFrom events and while it is working nicely for OnNavigatedTo, the later just wont work. It seems the Microsoft.Phone.Navigation assembly does not contain OnNavigatingFrom, and referencing System.Windows.Navigation, compiles ok, but I cant get pages to animate off upon navigation. I have a button on my Page2, which I want to go back to my MainPage (after I over-rided the back key with a message box for testing). I have transitions made on the page, and I have this as the event handler code... private void btnP2_BackToP1Clicked(object sender, System.Windows.RoutedEventArgs e) { NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.Relative)); } With this code for the OnNavigatedTo and OnNavigatingFrom events... protected override void OnNavigatedTo(PhoneNavigationEventArgs e) { PageTransition_In.Begin(); } // // protected override void OnNavigatingFrom(NavigatingCancelEventArgs e) { PageTransition_Out.Begin(); base.OnNavigatingFrom(e); } I have the feeling that OnNavigatingFrom may not(yet) be supported for Windows Phone Apps. OnNavigatedFrom is part of Microsoft.Phone.Navigation, but it only performs actions once the page is no longer active, which is too late to perform any animation effects.

• OpenGL depth buffer on Android

  - by kayahr

  I'm currently learning OpenGL ES programming on Android (2.1). I started with the obligatory rotating cube. It's rotating fine but I can't get the depth buffer to work. The polygons are always displayed in the order the GL commands render them. I do this during initialization of GL: gl.glClearColor(.5f, .5f, .5f, 1); gl.glShadeModel(GL10.GL_SMOOTH); gl.glClearDepthf(1f); gl.glEnable(GL10.GL_DEPTH_TEST); gl.glDepthFunc(GL10.GL_LEQUAL); gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST); On surface-change I do this: gl.glViewport(0, 0, width, height); gl.glMatrixMode(GL10.GL_PROJECTION); gl.glLoadIdentity(); GLU.gluPerspective(gl, 45.0f, (float) width / (float) height, 0.1f, 100f); When I enable backface culling then everything looks correct. But backface culling is only a speed-optimization so it should also work with only the depth buffer or not? So what is missing here?

• Which JavaScript framework for me?

  - by LeonixSolutions

  This is not to be a subjective question; nor is it intended to start a religious war. Which JavaScript framework for me? Until now, I haven't coded any JS at all (no biggy, it's just another language). I have been set in my ways and eschewed any client-side code, lest the user have JS turned off, or try to "just change this a little, to see what happens" - and then expect me to support it. So, until now it has all been server-side, with PHP and an ODBC compliant database. However, I am beginning to see advantages to client-side input validation and improved graphical experience for users which would help me to produce more professional web-based applications. I am looking for a framework which : doesn't have a steep learning curve is full-featured, although that does not mean that the one with the most features wins (remember the 80/20 rule) is mature an stable (even if still in development) integrates well with common IDEs if possible. I use NetBeans for PHP (and occasionally MS visual studio for C# (I seem to have drifted away from Eclipse)) allows me to develop web sites/apps for mobile devices support for Goggle charts (or other charting) would be a bonus has good AJAX/JSON support, but I imagine that they all do Taking that into consideration, is there a "right" framework for me, or does it not really matter? I looked briefly at JQuery and JQueryGui and liked what I saw, but I really don't have time, owing to deadlines, to try them all out and see which one suits me, much as I know that I ought to.

• How can I do batch image processing with ImageJ in clojure?

  - by Robert McIntyre

  I want to use ImageJ to do some processing of several thousand images. Is there a way to take any general imageJ plugin and apply it to hundreds of images automatically? For example, say I want to take my thousand images and apply a polar transformation to each--- A polar transformation plugin for ImageJ can be found here: http://rsbweb.nih.gov/ij/plugins/polar-transformer.html Great! Let's use it. From: [http://albert.rierol.net/imagej_programming_tutorials.html#How%20to%20automate%20an%20ImageJ%20dialog] I find that I can apply a plugin using the following: (defn x-polar [imageP] (let [thread (Thread/currentThread) options ""] (.setName thread "Run$_polar-transform") (Macro/setOptions thread options) (IJ/runPlugIn imageP "Polar_Transformer" ""))) This is good because it suppresses the dialog which would otherwise pop up for every image. But running this always brings up a window containing the transformed image, when what I want is to simply return the transformed image. The stupidest way to do what I want is to just close the window that comes up and return the image which it was displaying. Does what I want but is absolutely retarded: (defn x-polar [imageP] (let [thread (Thread/currentThread) options ""] (.setName thread "Run$_polar-transform") (Macro/setOptions thread options) (IJ/runPlugIn imageP "Polar_Transformer" "") (let [return-image (IJ/getImage)] (.hide return-image) return-image))) I'm obviously missing something about how to use imageJ plugins in a programming context. Does anyone know the right way to do this? Thanks, --Robert McIntyre

• Where do you take mocking - immediate dependencies, or do you grow the boundaries...?

  - by Peter Mounce

  So, I'm reasonably new to both unit testing and mocking in C# and .NET; I'm using xUnit.net and Rhino Mocks respectively. I'm a convert, and I'm focussing on writing behaviour specifications, I guess, instead of being purely TDD. Bah, semantics; I want an automated safety net to work above, essentially. A thought struck me though. I get programming against interfaces, and the benefits as far as breaking apart dependencies goes there. Sold. However, in my behaviour verification suite (aka unit tests ;-) ), I'm asserting behaviour one interface at a time. As in, one implementation of an interface at a time, with all of its dependencies mocked out and expectations set up. The approach seems to be that if we verify that a class behaves as it should against its collaborating dependencies, and in turn relies on each of those collaborating dependencies to have signed that same quality contract, we're golden. Seems reasonable enough. Back to the thought, though. Is there any value in semi-integration tests, where a test-fixture is asserting against a unit of concrete implementations that are wired together, and we're testing its internal behaviour against mocked dependencies? I just re-read that and I think I could probably have worded it better. Obviously, there's going to be a certain amount of "well, if it adds value for you, keep doing it", I suppose - but has anyone else thought about doing that, and reaped benefits from it outweighing the costs?

• javascript function not working in IE 7

• NSThread terminating too early

  - by JustinXXVII

  I have an app that uploads to Google Spreadsheets via the GData ObjC client for Mac/iPhone. It works fine as is. I'm trying to get the upload portion on its own thread and I'm attempting to call the upload method on a new thread. Look: -(void)establishNewThreadToUpload { [NSThread detachNewThreadSelector:@selector(uploadToGoogle) toTarget:self withObject:nil]; } -(void)uploadToGoogle { NSAutoReleasePool *pool = [[NSAutoReleasePool alloc] init]; //works fine [helper setNewServiceWithName:username password:password]; //works fine [helper fetchUserSpreadsheetFeed]; //inside the helper class, fetchUserSpreadsheet feed calls ANOTHER method, which //calls ANOTHER METHOD and so on, until the object is either uploaded or fails //However, once the class gets to the end of fetchUserSpreadsheetFeed //control is passed back to this method, and [pool release]; //is called. The thread terminates and nothing ever happens. } If I forget about using a separate thread, everything works like it's supposed to. I'm new to thread programming, so if there's something I'm missing, please clue me in! Thanks!

• Good patterns for loose coupling in Java?

  - by Eye of Hell

  Hello. I'm new to java, and while reading documentation so far i can't find any good ways for programming with loose coupling between objects. For majority of languages i know (C++, C#, python, javascript) i can manage objects as having 'signals' (notification about something happens/something needed) and 'slots' (method that can be connected to signal and process notification/do some work). In all mentioned languages i can write something like this: Object1 = new Object1Class(); Object2 = new Object2Class(); Connect( Object1.ItemAdded, Object2.OnItemAdded ); Now if object1 calls/emits ItemAdded, the OnItemAdded method of Object2 will be called. Such loose coupling technique is often referred as 'delegates', 'signal-slot' or 'inversion of control'. Compared to interface pattern, technique mentioned don't need to group signals into some interfaces. Any object's methods can be connected to any delegate as long as signatures match ( C++Qt even extends this by allowing only partial signature match ). So i don't need to write additional interface code for each methods / groups of methods, provide default implementation for interface methods not used etc. And i can't see anything like this in Java :(. Maybe i'm looking a wrong way?

• Bootstrapper (setup.exe) says ".NET 3.5 not found" but launching .msi directly installs application

  - by Marek

  Our installer generates a bootstrapper (setup.exe) and a MSI file - a pretty common scenario. One of the production machines reports a strange problem during install: If the user launches the bootstrapper (setup.exe), it reports that .NET 3.5 is not installed. This happens with account under administator group. No matter if they launch it as administrator or not, same behavior. the application installs fine when application.msi or OurInstallLauncher.exe (see below for explanation) is started directly no matter if run as administrator is applied. We have checked that .NET is installed on the machine (both 64bit and 32bit "versions" = under both C:\Windows\Microsoft.NET\Framework64 and C:\Windows\Microsoft.NET\Framework there is a folder named v3.5. This happens on a 64 bit Windows 7. I can not reproduce it on my development 64 bit Windows 7. On Windows XP and Vista, it has worked without any problem for a long time so far. Part of our build script that declares the GenerateBootStrapper task (nothing special): <ItemGroup> <BootstrapperFile Include="Microsoft.Windows.Installer.3.1"> <ProductName>Microsoft Windows Installer 3.1</ProductName> </BootstrapperFile> <BootstrapperFile Include="Microsoft.Net.Framework.3.5"> <ProductName>Microsoft .NET Framework 3.5</ProductName> </BootstrapperFile> </ItemGroup> <GenerateBootstrapper ApplicationFile=".\Files\OurInstallLauncher.exe" ApplicationName="App name" Culture="en" ComponentsLocation ="HomeSite" CopyComponents="True" Validate="True" BootstrapperItems="@(BootstrapperFile)" OutputPath="$(OutSubDir)" Path="$(SdkBootstrapperPath)" /> Note: OurInstallLauncher.exe is language selector that applies a transform to the msi based on user selection. This is not relevant to the question at all because the installer never gets as far as launching this exe! It displays that .NET 3.5 is missing right after starting setup.exe. Has anyone seen this behavior before?

• what webserver / mod / technique should I use to serve everything from memory?

  - by reinier

  I've lots of lookuptables from which I'll generate my webresponse. I think IIS with Asp.net enables me to keep static lookuptables in memory which I can use to serve up my responses very fast. Are there however also non .net solutions which can do the same? I've looked at fastcgi, but I think this starts X processes, of which anyone can handle Y requests. But the processes are by definition shielded from eachother. I could configure fastcgi to use just 1 process, but does this have scalability implications? anything using PHP or any other interpreted language won't fly because it is also cgi or fastcgi bound right? I understand memcache could be an option, though this would require another (local) socket connection which I'd rather avoid since everything in memory would be much faster. The solution can work under WIndows or Unix... it doesn't matter too much. The only thing which matters is that there will be a lot of requests (100/sec now and growing to 500/sec in a year), and I want to reduce the amount of webservers needed to process it. The current solution is done using PHP and memcache (and the occasional hit to the SQL server backend). Although it is fast (for php anyway), Apache has real problems when the 50/sec is passed. I've put a bounty on this question since I've not seen enough responses to make a wise choice. At the moment I'm considering either Asp.net or fastcgi with C(++).

• Am I Writing Assembly Or NASM?

  - by cam

  I'm fed up with this. I've been trying to just get a grip on assembly for awhile, but I feel like I'm coding towards my compiler rather than a language. I've been using this tutorial, and so far it's giving me hell. I'm using NASM, which may be the problem, but I figured it was the most popular one. I'm simply trying to learn the most general form of assembly, so I decided to learn x86. I keep running into stupid errors, like not being able to increment a variable. Here's the latest one: not being able to use div. mov bx, 0; mov cx, 0; jmp start; start: inc cx; mov ax, cx; div 3; <-- invalid combination of opcode and operand cmp ah,0; jz totalvalue; mov ax, cx; div 5; <-- invalid combination of opcode and operand cmp ah, 0; jz totalvalue; cmp cx, 1000; jz end; totalvalue: add bx,cx; jmp start; jmp end; end: mov ah,4ch; mov al,00; int 21h; Should I change compilers? It seems like division should be standard. Do I need to read two tutorials (one on NASM, and one on x86?). Any specific help on this problem?

• Calculate order price by date selection value

  - by albatross

  Alright, I know there's a simple way to do this, but it's been years since I've done much javascript My client has an online order form for event registration (developed by previous web dev.). Currently the order total is just a hidden field: <INPUT value=78.00 type=hidden name=amount /> But I need the total to calculate based on what date they choose: <SELECT style="BACKGROUND-COLOR: #ffff99" name=altDate1> <OPTION value=04/09> Friday, April 9 </OPTION> <OPTION value=04/14> Wednesday, April 14 </OPTION> <OPTION value=04/16> Friday, April 16 </OPTION> <OPTION value=04/19> Monday, April 19 </OPTION> <OPTION value=04/29> Thursday, April 29 </OPTION> </SELECT> This is the javascript that process the form: <SCRIPT language=Javascript> function PaymentButtonClick() { document.addform.Product_Name.value = document.Information.StudentLastName.value + ","+ document.Information.StudentFirstName.value+","+ document.Information.StudentID.value+","+ document.Information.altDate1.name+","+","+ document.Information.Guests.value+ "," + document.Information.StudentType.value; document.addform.Product_Code.value = document.Information.StudentID.value; if ((document.Information.UCheck.checked==true) && (document.Information.altDate1.value != "") && (document.Information.altDate1.value != "x")) { if (document.Information.StudentLastName.value != "" || document.Information.StudentFirstName.value != "" || document.Information.StudentID.value != "" ) { document.addform.submit(); } else { alert("Please enter missing information"); } } } </SCRIPT>

• AJAX - querying a search engine and returning the number of results

  - by Moddy

  Right, so basically I need to query a selection of search engines in an AJAX app. As there is a number of different search engines - there's no search engine specific API I can use either. My main problem is getting the number of results returned by the search. So far, I have decided it is probably best to use a regexp from the returned search query HTML, and then convert the string of characters to an integer. However, this method just doesn't feel.. clean to me. It seems a bit rough around the edges and I think it could do with improving! I guess not being 100% confident with regular expressions doesn't help; but it just feels like it could be improved. Any ideas on how to implement this would be great cheers! It doesn't seem like that an exotic thing to do, so I was wondering if perhaps any of you guys have done this before and would have a few tips? Note: This is an AJAX app at the moment, but I may be re-writing this functionality in a different app soon - which won't be AJAX. I'm confident I can transfer any AJAX implementation to the other language though.

• Internet Explorer cannot 'fully' load ActiveX Control

  - by K Browne

  Context I am migrating an installer for an ActiveX control from Per-Machine to Per-User. I did this by programming the installer write to HKCU\Software\Classes instead of HKLM\Software\Classes. Problem On my machine (Windows 7 with UAC Enabled), the ActiveX control successfully loads. On the other windows 7 test machines (one with UAC enabled, one with UAC disabled), the control 'partially' loads. What is Partially? When a user visits a page with the ActiveX control, Internet Explorer displays a warning message in a yellow bar on the top of the window. If you click the 'Run add-on' button in the bar, the control becomes visible and begins to run, but Javascript code that tries to access properties of the control return the error: Library not registered. Differences between machines On the dev machine reads from HKCR\CLSID\<GUID> succeed while on the test machines these reads fail. Reads from HKCU succeed on both dev and test machines. Reads from HKLM fail on both test and dev machines. (I collected reads using Sysinternals Process Monitor) Strangely, the keys that Internet Explorer fails to read are clearly visible if I use regedit to view HKCR\CLSID\<GUID> on the test machines. Question What can I do to get the per-user control to load on the test machines? What could cause this difference between the dev machine and the test machines? Why can I see the key in HKCR with RegEdit but Internet Explorer cannot see the key? Any help is appreciated. Thank you.

• if (i == 2) or if (2 == i) ?

  - by Maroloccio

  I usually use if (i == 2) in preference to if (2 == i) On occasion, I would switch things around when writing xUnit-type tests from scratch so as to follow the assertion convention of "expected" preceding "actual". When adding to existing unit tests, I always follow the style I find. No matter what, I always try to keep things consistent. Today I checked out some code with a lot of "if (2 == i)" and started wondering: which style is more "popular" nowadays? is popularity language-dependent? The latter probably because I am aware of why the "if (2 == i)" became common in the first place (C heritage) and because I see some languages go as far as disallowing assignments within conditions (e.g. Python). I thought about downloading some sources: apt-get source linux-source eclipse openoffice.org expanding them and performing a quick grep: grep --color --include=*.java --include=*.c -ERI \ "if[[:space:]]*\([[:space:]]*[[:digit:]]+[[:space:]]==" . or creating a quick "poll": http://goo.gl/mod/ciMF after a bit of searching and asking around, I am still not sure. So I am asking you: which way to go?

• Keyboard input: how to separate keycodes received from user

  - by Iulian Serbanoiu

  Hello, I am writing an application involving user input from the keyboard. For doing it I use this way of reading the input: #include <stdio.h> #include <termios.h> #include <unistd.h> int mygetch( ) { struct termios oldt, newt; int ch; tcgetattr( STDIN_FILENO, &oldt ); newt = oldt; newt.c_lflag &= ~( ICANON | ECHO ); tcsetattr( STDIN_FILENO, TCSANOW, &newt ); ch = getchar(); tcsetattr( STDIN_FILENO, TCSANOW, &oldt ); return ch; } int main(void) { int c; do{ c = mygetch(); printf("%d\n",c); }while(c!='q'); return 0; } Everyting works fine for letters digits,tabs but when hiting DEL, LEFT, CTRL+LEFT, F8 (and others) I receive not one but 3,4,5 or even 6 characters. The question is: Is is possible to make a separation of these characters (to actually know that I only hit one key or key combination). What I would like is to have a function to return a single integer value for any type of input (letter, digit, F1-F12, DEl, PGUP, PGDOWN, CTRL+A, CTRL+ALT+A, ALT+LEFT, etc). Is this possible? I'm interested in an idea to to this, the language doesn't matter much, though I'd prefer perl or c. Thanks, Iulian

• Go: using a pointer to array

  - by Sean

  I'm having a little play with google's Go language, and I've run into something which is fairly basic in C but doesn't seem to be covered in the documentation I've seen so far When I pass a pointer to an array to a function, I presumed we'd have some way to access it as follows: func conv(x []int, xlen int, h []int, hlen int, y *[]int) for i := 0; i<xlen; i++ { for j := 0; j<hlen; j++ { *y[i+j] += x[i]*h[j] } } } But the Go compiler doesn't like this: sean@spray:~/dev$ 8g broke.go broke.go:8: invalid operation: y[i + j] (index of type *[]int) Fair enough - it was just a guess. I have got a fairly straightforward workaround: func conv(x []int, xlen int, h []int, hlen int, y_ *[]int) { y := *y_ for i := 0; i<xlen; i++ { for j := 0; j<hlen; j++ { y[i+j] += x[i]*h[j] } } } But surely there's a better way. The annoying thing is that googling for info on Go isn't very useful as all sorts of C\C++\unrelated results appear for most search terms.

• Random point on VideoDisplay isn't accurate enough

  - by Mike

  For a schoolassigment me and some buddies of mine are creating an application that is showing many similarities with the C-Mon & Kypski musicvideo on www.oneframeoffame.com. The application is being developed in Flex. We want to get a random point of a clip, let it pause so a user can mimic the pose and make a snapshot out of it. What i managed to do is get a random point of the movie. I did this by getting a random value between 0 and de total duration of the movie. But what i didn't managed to do is let the screen pause on every 24st of a frame. As the movie concist out of 24FPS. It looks like the the random value of the movie that is being requested is being rounded by the movie itself. As example: There appears to be no difference between the frames requested at 2.40 or 2.41. It appears it got something to do with keyframing i've read on the Adobe® Flex™ 3.5 Language Reference. The movie is a FLV file and i use the VideoDisplay object to display the movie. Does someone is familiar with this or knows a solution to my problem? Thanks in advance

• How to configure outgoing connections from an SQL stored procedure?

  - by Peter Vestberg

  I am working on a .NET project which uses Microsoft SQL server. In this project, I need a CLR stored procedure (written in C#) that uses a remote web service. So, when the stored procedure is executed on the SQL server, it makes web service calls and thus sends packets to a remote location. The problem is that when executing the SP I get: "System.Net.WebException: The request failed with HTTP status 403: Forbidden." The database user has full permission, the deployed CLR assembly and SP are even marked "unsafe", I tried signing it etc., so any of that is not causing the problem. When I am executing the very same C# code, but from a simple console application instead of as a SP, it all works fine. So I started to suspect a network related problem and had a packet sniffer running when executing both the SP and the console app version. What I realized was that the packets sent out had different destination IP addresses: the console app sent the packets directly to the web service IP while the SP sent the packets to a proxy server we use in our company. Due to network policies the latter is not allowed and that explains the "403 Forbidden" exception. So my question boils down to this: How can I configure the SP/MS SQL server to NOT use that proxy? I want it to send the packets directly to the web service IP, just like the test console app. (again, the C# code is the same , so it's not a programming matter). I've disabled all proxy settings in Internet Explorer in case the SQL server inherits these settings or something. However, no luck. Any help would be greatly appreciated! Best regards, Peter
