• is there a tool to see the difference between two database tables in mssql?

  - by reinier

  What is a good tool to see the differences between 2 tables (or even better, the datasets returned by 2 queries). EDIT: I'm not interested in the schema changes. Just assume that the schemas are the same. background as to why: I'm porting some legacy code which can fill a database with some pre-calced data. The easiest way to see if I got everything right, is to check the output of the old program, with the new one. I was thinking that if there is some kind of 'diff' tool for databases, this might be great.

• dynamically updating a datagrid from a XML file c# 3.5

  - by Farstucker

  I have a datagrid that is populated via XML file when the form loads. Everything is working great but I would like the datagrid to update dynamically when a new order is received (Separate class receives a data stream and updates the file). Im looking for suggestions on how this should be done. (ie using a timer update every second, or monitor the file using FileSystemWatcher.. etc) Since where here, I might as well mention that in order to update the datagrid Im clearing the whole data set and Re-reading the file using: DataSet.Clear(); DataSet.ReadXml("file.xml"); dataGridView1.DataSource = DataSet; if this is not the proper approach, please offer any alternate suggestions.

• Can I move the order of XCode, Cocoa, and User Templates around in XCode 3.1?

  - by Warren P

  I followed the other questions on StackOverflow and made custom User Templates. Instead of replacing the factory default Cocoa class template, I have to pick a new user template. The order that is shown in XCode's New File dialog box is: iPhone templates first (great if you mostly do iphone development) Second the User templates Third the default Mac OS templates. I want my user stuff first, Mac OS templates second, and I want to bury iPhone templates in third and last place. The sort is obviously not alphabetical. And you can't drag/drop reorder. (At least not in xcode 3.1.3)? From stackoverflow

• Is webserver bandwith the entire HTTP Request/Responce?

  - by Lienau

  Just a quick question. I'm making a web application where C++ communicates with a php script over HTTP Requests/Response. The data being set back and forth is quite small ~36 bytes. But I plan to have many computers connected, contacting the server quite often. I did the math, and I could potentially have gigabytes of data transfer a month. This isn't too much of problem, but it would be if the bandwidth included the request/response headers the request size would be about ~560 bytes. That's about 16x more bandwidth than I was planning... That would be a lot. If if any one knew how host determine bandwidth and could share, that'd be great. Thanks.

• Using NSThread to solve waiting for image from URL on the iPhone

  - by james.ingham

  So I have the following code in a method which I want to set a UIImageView image to that of one from an online source: [NSThread detachNewThreadSelector:@selector(loadImage) toTarget:self withObject:nil]; Then in the method called by the thread I have this: - (void) loadImage { NSURL *url = [NSURL URLWithString:logoPath]; // logoPath is an NSString with path details NSData *data = [NSData dataWithContentsOfURL:url]; logoImage.image = [UIImage imageWithData:data]; } This works great however I get many warnings within the Debugger Console along the lines of: 2010-05-10 14:30:14.052 ProjectTitle[2930:633f] * _NSAutoreleaseNoPool(): Object 0x169d30 of class NSHTTPURLResponse autoreleased with no pool in place - just leaking This occurs many times each time I call the new thread and then eventually, under no pattern, after calling a few of these threads I get the classic 'EXC_BAD_ACCESS' run-time error. I understand that this is happening because I'm not retaining the object but how can I solve this with the code in 'loadImage' shown above? Thanks

• Django remove list_editable on a per row basis.

  - by Jason Leveille

  On the back of Django 1.2RC1, I have built a great administrator for my client! It's awesome. The client has one request that, if not satisfied, could bring this house of cards crashing down. I have a list of swim meet results. A meet result is added by a superuser. A team rep can edit a meet result (which they must be able to do inline, with list_editable), but after they edit the meet result inline and save, they should no longer be able to edit that result inline. They can only perform one edit. So, my question ... can I turn off list_editable on a per row basis?

• Best option for Google App Engine Datastore and external database?

  - by Alex

  I need to get an App Engine app talking to and sharing data with an external database, The best option i can come up with is outputting the external database data to an xml file and then processing this in my app engine app and storing it inside the datastore, although the data being shared is sensitive data such as login details so outputting this to an xml file is not exactly a great idea, is it possible for the app engine app to directly query the database? or is there a secure option for using xml files? oh and im using python/django and the external database will be hosted on another domain

• Error on Access database: Permission denied: 'CreateObject'

  - by elixireu

  Hi, I am migrating a website over to a new server, its in ASP and uses several Access databases, the site and CMS can read, display the data, and even edit and update existing data entries, but when I want to add a new entry, I get an error... Microsoft VBScript runtime error '800a0046' Permission denied: 'CreateObject' /padp2010d/ads_tradetracker.asp, line 11 There seems to be no passwords on the databases, I have set up and tested the ODBC Data Sources and they are working fine. The code or line that is causing the problem is... <% Dim Mail, strPath, strHost, Upload Set Upload = CreateObject("Persits.Upload") Upload.IgnoreNoPost = True ' Generate unique names Upload.OverwriteFiles = False ' Limit file size to 500000 bytes Upload.SetMaxSize 500000, True ' capture an upload and save uploaded files (if any) in temp directory Upload.SaveVirtual "\pa\images\advertenties" Upload.Save ' Use session ID as the new file name NewName = Session.SessionID The line 11 is Set Upload = CreateObject("Persits.Upload") If anyone could help that would be great. Could it be a Permission setting? Im a complete novice with ASP and Access! Thanks

• Can any JavaScript library perform as well as the Cut The Rope JavaScript implementation?

  - by joe

  Now that the canvas tag is starting to get hardware execration [acceleration - thanks guys!] by many browsers, developing casual games in HTML5 is becoming more feasible. ZeptoLabs did a great job porting Cut The Rope to HTML5 for use as a Windows 8 Metro App. You can find some of the details here but they do not get into specifics. I was wondering if anyone knew if they used a library (such as Impact or Crafty) or if you need to write all custom and optimized JavaScript code in order to get this type of performance. Thanks!

• Open Safari from within Opera Mini on the iPhone

  - by Ican Zilb

  Now that Opera Mini is becoming so popular in the App store I want to effectively warn my web site visitors that the rendition they see in Opera Mini is far from what I meant them to see and redirect them to my page in Mobile Safari, so they can enjoy HTML5 and CSS3. I've been banging my head around that task all day long, but I can't seem to find a solution. My hope lies in the custom URL schemes, but seems Opera Mini handles all schemes which usually Safari does. Would be great if there's a scheme like safari://www.domain.com which opens ONLY in Safari, so I can redirect the visitors to it. Does anybody know a solution to that problem? --edit Just to make myself clear - browser detection is not the problem (I'm doing Javascript for 13 years now) the question is if there's a way to invoke the Safari app on the iPhone from within a web page which is being viewed in Opera Mini.

• Twitter @anywhere API problems in firefox only

  - by Brian Scott

  I've implemented a simple example of the Twitter @anywhere api to display user hovercards. The example works great in Internet Explorer and Chrome. However, whenever I the page loads in Firefox I receive the following message in an alert window: To set up @anywhere, please provide a client ID Surely if the results are correct in Chrome and IE then everything must be setup correctly? Here is a simple code block which I've tested recreates the problem in Firefox only: <script src="http://platform.twitter.com/anywhere.js?id=WMg5kRMlIw807lRTsktnNQ&amp;v=1" type="text/javascript" > </script> <script type="text/javascript"> twttr.anywhere(onAnywhereLoad); function onAnywhereLoad(twitter) { twitter().hovercards(); }); </script>

• Seam app with JBoss 'minimal' Config?

  - by Shadowman

  I'd like to improve the performance of my Seam apps and JBoss appserver, particularly by removing things that aren't necessary in the standard configuration. Ideally, I'd like to be able to run it using the "minimal" profile. Can anyone give me any guidance as to what is needed to run a Seam app using "minimal"? Here are the kind of things my app requires: JPA, using Hibernate with a PostgreSQL backend EJB3 JSF (RichFaces/Facelets) E-mail, eventually, although not required at this particular moment I'll be developing my app using JBoss Tools on Eclipse, so I would also need anything that is required by the tools for development and deployment. I've found that the default configuration just has too many additional components and features installed by default, and that greatly affects performance when I'm trying to develop. Any help you can give would be great! Thanks!

• Android Developers, Are you adding APP 2 SD in a future app release and if so for which applications

  - by Anthony

  For Android application developers regarding 2.2 and the new App 2 SD feature. Android 2.2 now allows you to have your applications installed onto the SD card instead of using the phones internal memory. Will any of you be adding this feature onto your next release and if so what is your app? I know applications built with the App 2 SD function cannot be used when the SD card is mounted. Maybe 2 versions of each app on the market would work out great for those that would need an app while the phone is mounted. What do you think about this idea? Are you aware of any other negative issues that arise from an application built for this feature?

• generate Grid from template

  - by theXs

  Howdy, I've got another question regarding phone 7... I want to generate a couple of Grids in a stackpanel - since they all have the same layout I thought it would be a great idea to use DataTemplates ... But then I found that the GRID Object has no "DataTemplate" Property and now I'm kinda stuck ... the template which I use is the following: <DataTemplate x:Key="Speise"> <Grid> <TextBlock Height="36" Margin="8,43,104,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top"/> <TextBlock HorizontalAlignment="Right" Height="36" Margin="0,44,8,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top" Width="92"/> </Grid> </DataTemplate> The way I now thought of creating my objects is: Grid blubber = (Grid)this.Resources["Speise"]; But that is not working ... I think it's again a really short thing, but I have no clue of how to google for it :(

• Deserialize array values to .NET properties using DataContractJsonSerializer

  - by James Cadd

  I'm working with the DataContractJsonSerializer in Silverlight 4 and would like to deserialize the following JSON: { "collectionname":"Books", "collectionitems": [ ["12345-67890",201, "Book One"], ["09876-54321",45, "Book Two"] ] } Into classes like the following: class BookCollection { public string collectionname { get; set; } public List<Book> collectionitems { get; set; } } class Book { public string Id { get; set; } public int NumberOfPages { get; set; } public string Title { get; set; } } What's the proper place to extend DataContractJsonSerializer to map the unnamed first array element in "collectionitems" to the Id property of the Book class, the second element to the NumberOfPages property and the final element to Title? I don't have control over the JSON generation in this instance and would like the solution to work with the Silverlight subset of .NET. It would be great if the solution could perform the reverse for serialization as well.

• Interpreted vs. Compiled vs. Late-Binding

  - by zubin71

  Python is compiled into an intermediate bytecode(pyc) and then executed. So, there is a compilation followed by interpretation. However, long-time Python users say that Python is a "late-binding" language and that it should`nt be referred to as an interpreted language. How would Python be different from another interpreted language? Could you tell me what "late-binding" means, in the Python context? Java is another language which first has source code compiled into bytecode and then interpreted into bytecode. Is Java an interpreted/compiled language? How is it different from Python in terms of compilation/execution? Java is said to not have, "late-binding". Does this have anything to do with Java programs being slighly faster than Python? Itd be great if you could also give me links to places where people have already discussed this; id love to read more on this. Thank you.

• Setting User Access Rights in Windows

  - by user314282

  Can someone tell me how to set file permissions in Delphi 2006? I am using TINIFile.Create to create INI files in my application. The problem is that if I create the file while logged onto Windows as an administrator and then try to run the application as just a standard user and overwrite the INI file, I do not have permission to do so. I put the file in the AllUsers\ApplicationData\MyProduct folder. I'd like to set the permissions to this folder. I need AllUsers to have Full permissions to the MyProduct folder. If its possible to do this through a WindowsAPI that'd be great because I also need to do this in C++ and C#. I'd really appreciate any help. Thanks!

• Newbie question on MvcContrib TestHelpers

  - by Simon Lomax

  Hi, I'm just starting to use the TestHelpers in MvcContrib. I want to try and test an action method on my controller that itself tests if IsAjaxRequest() is true. I've used the same code that is shown in the TestHelper samples to set up the TestControllerBuilder _controller = new StarsController(); _builder = new TestControllerBuilder(); _builder.InitializeController(_controller); So that _controller has all the faked/mocked HttpContext inside it, which is really great. But what do I do now to force IsAjaxRequest() on the internally faked Request object to return true?

• How to write my own download manager using Objective C for iOS devices

  - by Saurabh

  I am writing a download manager for iPhone using objective C. I am using ASIHTTP framework and its working great. But my problem is I am not able to download from file sharing sites like filesonic, rapidshare, hotfile etc. I want to know how can I get download (actual download) url from these sites, or at least how these sites are hiding this info (and where), so I can get that somehow... Is there any open source library or framework to help me with this? How firefox or other desktop browser get this link? Any help will be much appreciated! Update 1 : I don't want to bypass their advertising and revenue streams. Almost all file sharing companies also provide free downloads with low bandwidth, I only want to use that service. there are many download managers available now for iPhone like - "Downloads Lite". I just want to build a similar functionality.

• PL DOC source forge - 2 issues

  - by user1792793

  I'm attempting to use PLDOC source forge (http://pldoc.sourceforge.net/maven-site/) with my code to generate a neat page with comments of my liking. I'm coming across 2 issues, any help would be appreciated. 1 I've been using tags (/**, */) to make comments and this works perfectly for functions, but does not appear in procedures. My Functions and procedures are independent and not in packages, and trying to add comments before the PROCEDURE declaration just gets deleted when saved. 2 if i try to use the recommended method of getting the data directly from teh database (call pldoc.bat -url jdbc:oracle:thin:@localhost:1521:ORCL -user SCOTT -password TIGER -sql SYS_OWNER.DBMS_PIPE,SYS_OWNER.DBMS_OUTPUT), it puts all the available functions and procedures under the user SIS_OWNER (SIS_owner is the only link available on the left hand side). I want to change this so that I can view all the methods in the list instead. Problem with procedures stated in 1 still exists with this method. Please let me know if you have overcome this and any pointers would be great. Thanks

• Is is possible to make a shaped, alpha-blended dialog?

  - by jgaa

  I'm making a non-rectangular dialog, modelled over an image from Photoshop (the image is the background of the dialog, and the user will see trough the transparent part of the image). I'ts like a dashboard-style window for a media-app with a few custom-drawn controls. Most of the background-image is either opaque or 100% transparent - but in between there is a thin area of partially transparent pixels, ment to blend the image smootly into the background. This works great for web-graphics, but I have not found a way to make this work for Windows windows. I'm using the Windows Template Library (WTL), msvc 2008 - and the app must run on Windows XP as well as Vista and Windows 7. Currently, I'm simply using the opaque part of the background-image to create a GDI clipping-region, but this gives pretty rough edges. Does anyone know about any API functions to accomplish this (part of WTL, or reachable from WTL)?

• Best tools / formats for documenting XML API?

  - by ivant

  We are developing XML over HTTP service and we need a way to document the XML interface. Our supported XMLs generally are subsets of some industry standard XML API, which unfortunately lacks any good documentation. It has XSDs though with some annotations, so we use this go generate the initial documentation and then remove the unsupported parts and refine the result. But this process is tedious and the results aren't at all great. Any suggestion about documentation formats and tools? I prefer to have HTML output and possibly more, e.g. PDF. Oh, and we are mixed Linux and Windows shop, so the tools should work well on both.
