• 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.

• python - from matrix to dictionary in single line

  - by Sanich

  matrix is a list of lists. I've to return a dictionary of the form {i:(l1[i],l2[i],...,lm[i])} Where the key i is matched with a tuple the i'th elements from each list. Say matrix=[[1,2,3,4],[9,8,7,6],[4,8,2,6]] so the line: >>> dict([(i,tuple(matrix[k][i] for k in xrange(len(matrix)))) for i in xrange(len(matrix[0]))]) does the job pretty well and outputs: {0: (1, 9, 4), 1: (2, 8, 8), 2: (3, 7, 2), 3: (4, 6, 6)} but fails if the matrix is empty: matrix=[]. The output should be: {} How can i deal with this?

• JFrame.setBackground() not working -- why?

  - by devoured elysium

  JFrame mainFrame = new JFrame(); mainFrame.setSize(100, 100); mainFrame.setBackground(Color.CYAN); mainFrame.setVisible(true); My intent is to create a window with a cyan background. What is wrong with this? My window doesn't get cyan, as I'd expect! Also, could anyone point out why I seem to have all the colors in duplicate (there's a Color.CYAN and a Color.cyan). Is there any difference at all between the two? Maybe the older one was a constant from before there were enums in Java and the second one is from the Enum? Thanks

• Book for a Windows Application

  - by cateof

  Hello everybody. I want to create an small GUI Windows application that looks like all the other usual appz. I am searching for a book that describes the whole procedure. Let's say an address book application that can be have a small database, minimized in the task bar, doing things in the background and so on. I don't care for the language. But I would prefer to do it in .NET C++. I know it is a "very" general question, so Thanks in advance.

• Assign values on multi-properties to a object

  - by Lu Lu

  I have a object which it was initialized before in a base class. In inherited class, I use this object and assign values on multi-properties to it. Example: this.Chart.X = 10; this.Chart.Y = 10; this.Chart.Width = 20; this.Chart.Height = 20; this.Chart.Background = Color.Red; However, I must repeat "this.Chart" many times. How to avoid this. Note that I don't want to re-create this object again because in the base class, it was initialized with some common values. Thanks.

• Visual Studio Unit Testing of Windows Forms

  - by GWLlosa

  We're working on a project here in Visual Studio 2008. We're using the built-in testing suite provided with it (the Microsoft.VisualStudio.TestTools.UnitTesting namespace). It turns out, that much to our chagrin, a great deal of complexity (and therefore errors) have wound up coded into our UI layer. While our unit tests do a decent job of covering our business layer, our UI layer is a constant source of irritation. We'd ideally like to unit-test that, as well. Does anyone know of a good "Microsoft-compatible" way of doing that in visual studio? Will it introduce some sort of conflict to 'mix' unit testing frameworks like nUnitForms with the Microsoft stuff? Are there any obvious bear traps I should be aware of with unit-testing forms?

But if a client clicks anyother popup window in the form that popup window will not be blocked by the browser.

• Postgres : Post statement (or insert) asynchronous, non-blocking processing.

  - by Hassan Syed

  I'm wondering if it is possible, that after a collection of rows is inserted, to initiate an operation that is executed asynchronously, is non-blocking, and doesn't need to inform the originator of the request - of the result. I am working with large amounts of events and I can guarantee that the post-insert logic will not fail -- I just want to have a single insert thread in my event-sources, and I want this thread to keep flying without blocking, and without being responsible for any post-delivery book-keeping. I can tell you that I would potentially have a 100 of these jobs executing concurrently and each job might operate on 5 tables with anywhere between 200-1000 inserts on each of these tables. A hint in the right direction should be enough.

• Best anti boss tricks to hide your private page navigation from your desktop.

  - by systempuntoout

  This question is slightly related to programming and it's kinda lame, i know; but i saw many funny things in these years and i'm looking for new tricks from you. I'm talking about methods to fast-hide\camouflage not job related web pages on your desktop when boss arrives like a ghost\ninja behind your shoulders. I know how much can be frustrating, programming hard for ten hours and then been caught by your boss watching XKCD during a 2 minutes break. I think the most common anti boss trick is the evergreen CTRL+TAB, but you have to be fast and your left hand has to be near the keyboard. I saw pitch black brightness on Lcd (how can you pretend to program on that?) or custom sized browser to fit a little space just below the IDE. My favourite one at the moment is using fire gesture plugin with FF; with a micro gesture you can hide FF to your tray in a blink of an eye. Do you have any trick to share?

• long running process in asp.net C#

  - by user339323

  Hello All, I have a web application that has a long running (resource intensive) process in the code behind and the end output is a pdf file (images to pdf conversion tool) It runs fine..and since I am on a dedicated server, it is not at all a problem with respect to resources right now. However, I wonder that the system would reach its resource limits if, there are more than 20 users processing at a time. I have seen services online where the user enters their email and the processes are, I suppose, queued in the background and the results emailed with the 1st in 1st out method. Can someone please give me a start on how to implement this kind of logic in asp.net applications using C#? Thanks a lot in advance, Prasad.

• Time order of messages

  - by Aiden Bell

  Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and(answered below) is there any guarantee of order when processing messages? ie. Received in order sent? If so, how is clock skew handled in high traffic situations for ordering? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

• Is there a smart web developer language skill combination?

  - by Cryo

  I'm no newbie to programming, but I'm making the move to a career in web development, and I've noticed that so many job postings have different combinations of skill requirements: (PHP, C#, XML, XHTML/CSS, ASP, .NET, jQuery, YUI, Joomla, Ruby, Perl, Python, Java, Javascript... the list goes on.) As of now, I've started learning XHTML, CSS, JavaScript, jQuery, PHP, and mySQL, but with so many combinations, I want to plan ahead to have a marketable combination of skills as early on as possible. Am I on the right path? What is vital for a marketable web programmer's arsenal? Thanks for your thoughts.

• Getting user data from Active Directory using PL/SQL

  - by David Neale

  I had a discussion today regarding an Oracle procedure I wrote some time ago. I wanted to get 7500 user email addresses from Active Directory using PL/SQL. AD will return a maximum of 1000 rows and the LDAP provider used by Oracle will not support paging. Therefore, my solution was to filter on the last two characters of the sAMAccountName (*00,*01,*02...etc.). This results in 126 queries (100 for account names ending in digits, 26 for those ending in a letter...this was sufficient for my AD setup). The person I was speaking to (it was a job interview by the way) said he could have done it a better way, but he would not tell me what that method was. Could anybody hazard a guess at what this method was?

  Hi, hows it going, I have searched through the forums and good old google and have found many answers but non seem to work on my page. Anyway here is the question, I have 2 divs that are positioned side by side, and I wish to get rid of the whitespace www.blisshair.com.au/test.html :(http://www.blisshair.com.au/test.html) I want to the black from the "link 1" to join to the main content in the center, Any help would be greatly appreciated, Thank you. EDIT: Tried opening in Internet explorer 8 and it seems top exactly how I want it, besides the 2 bottom divs not lining up, Is it possible to do this with an UL and SPAN tags ? I am aiming for a tabbed look, for example, when you click on link 2, the background around link 2 goes black and the black color "flows" into the main content page, sorry if this doesnt make sense, early AM here :D Thanks again

• Reading from the HTML DOM returns UTF-8 characters

  - by teehoo

  I have a contenteditable div where I'm reading individual characters and sending them off to a server (for more background this is similar to Google Wave where typing a character automatically sends it) I was using a plain old html textfield before and everything worked fine until I "upgraded" to a contenteditable div. My problem is that now the characters are in UTF-8 format, which is causing some weird problems on the server that I would rather not debug. It would be much easier to force everything to be ASCII on the client side. Is there any way to do this? I tried putting in a meta tag stating the html file is charset=ISO-8859-1, but it doesnt seem to work. Reading from the div tag still returns UTF-8 codes. (One example is when I press space I get the pair 0xC2 0xA0 which corresponds to a "non-breaking white space"

• Subversion: What to do with branches, tags and trunk folders?

  - by bartclaeys

  A little background first: I'm a designer/developer and decided to use subversion for a personal project. I'm the only one working on this project. I've setup a Beanstalk account and installed Versions on Mac. Locally I have MySQL and PHP running through MAMP. First thing I did in Versions is click the 'checkout' button. I selected my webroot folder and a folder has been created with three subfolders: branches, tags, trunk. I don't understand what to do with this. My code lives in the webroot and a bunch of subfolders and I can't move my code to any of the three folders without breaking things. So, my question is, how do I tell Versions that my code is in the webroot folder and not in the folder it created itself?

• Using formLabel in FormPanel for Localization

  - by user1782712

  I am trying to implement Localization within a panel, so to make the fieldLabel accessable from another file I am defining it like this Ext.define('Ext.app.detailForm', { extend: 'Ext.form.Panel', id: 'cscForm', // frame: true, uncomment this to show blue frame background title: 'CSC Details :', //trying cscCode: 'CSC Code', bodyPadding: 5, layout: 'anchor', // Specifies that the items will now be arranged in columns autoScroll: true, //width:1200, //height: 300, collapsible: true, fieldDefaults: { labelAlign: 'left', msgTarget: 'side' }, items: [{ columnWidth: 0.4, xtype: 'container', layout:'anchor', defaults: { labelWidth: 150 }, defaultType: 'textfield', items: [{ xtype: 'container', layout: 'hbox', items:[{ xtype: 'fieldset', columnWidth:1.5, layout: 'column', width:1050, defaultType: 'textfield', defaults: { labelWidth: 150, margin: '3 0 0 10' }, items: [{ fieldLabel: this.cscCode, name: 'CSCCode', width: 500 }, {..... but when I try to render this panel, the formLabel for cscCode does not display, is there some thing which I am doing wrong here? I am basically not able to access "this.cscCode"

• Add HTML Id's to tags in .aspx file

  - by slandau

  So I'm writing an app that lets the user select a folder, it gets all the .aspx files in that folder, and lets the users check off which ones they want to add HTML ID's to. Then they click start, and this runs private void btnStart_Click(object sender, EventArgs e) { for (int i = 0; i < listFiles.CheckedItems.Count; i++) { } } It loops through all the selected file names. How do I open each of these .aspx files in the background, and go through them and add the id="thisItemId" attribute to each tag that's like a , , , , , etc....

• .NET WebService IPC - Should it be done to minimise some expensive operations?

  - by Kyle

  I'm looking at a few different approaches to a problem: Client requests work, some stuff gets done, and a result (ok/error) is returned. A .NET web service definitely seems like the way to go, my only issue is that the "stuff" will involve building up and tearing down a session for each request. Does abstracting the "stuff" out to an app (which would keep a single session active, and process the request from the web service) seem like the right way to go? (and if so, what communication method) The work time is negligible, my concern is the hammering the transaction servers in question will probably get if I create/drop a session for each job. Is some form of IPC or socket based communication a feasible solution here? Thoughts/comments/experiences much appreciated. Edit: After a bit more research, it seems like hosting a WCF service in a Windows Service is probably a better way to go...

• Float over two elements

  - by eWolf

  My problem is rather complex to explain, so I'll show you an example: http://ewolf.bplaced.de/misc/float.htm I want to have a floated element (the blue box) to be be placed over two other elements (red and green) and I want the whole thing to be fixed-width and centered (done by the box with the black border) while the background of the red and green box should fill the whole width. I'm actually not quite sure if the way I've done it now is XHTML/CSS valid, but it works - at least in Firefox. In IE6, the green box expands to fit the whole blue box - how can I fix this in IE6 or find another solution to show it correctly in all browsers?

• What is the best approach to manipulate assets in Drupal from .Net application?

  - by Amandeep Singh

  I'm beginning work on a project that will access a Drupal site to create nodes on the site. This includes file uploading, as the project is to allow people to upload pictures en mass to a Drupal site with minimal ado. Note that my application is written in .Net. What I would like to know is the best approach to achieve the same? Based on initial research it looks like there are several options: 1. XML-RPC 2. Custom PHP module deployed in drupal. But, what is the way to invoke it from .Net? 3. Use a cron job to pick up the files from a watch folder. And add a cron_hook in my module to deploy the file.

• Android RelativeLayout spacing

  - by fordays

  Hi, I'm just putting the finishing touches to my Android app. Unfortunately, I dug straight into development without reading the documentation and built my layout with AbsoluteLayout and it turned out to look terrible when I loaded the app on my phone. Now I'm redoing the UI in a RelativeLayout and I want to put empty canvas space in between my ViewGroups in the y-direction. I am currently achieving this by putting random TextView sentences that are of the same color as my View's background in order to make psuedo-empty space. Is there a better way to do this, because right now when I define a specific ViewGroup to be placed below another View, it gets stuck right below the top View. As I was writing this, it dawned upon me that using padding might be the answer.... Any other suggestions?

• Should Factories Persist Entities?

  - by mxmissile

  Should factories persist entities they build? Or is that the job of the caller? Pseudo Example Incoming: public class OrderFactory { public Order Build() { var order = new Order(); .... return order; } } public class OrderController : Controller { public OrderController(IRepository repository) { this.repository = repository; } public ActionResult MyAction() { var order = factory.Build(); repository.Insert(order); ... } } or public class OrderFactory { public OrderFactory(IRepository repository) { this.repository = repository; } public Order Build() { var order = new Order(); ... repository.Insert(order); return order; } } public class OrderController : Controller { public ActionResult MyAction() { var order = factory.Build(); ... } } Is there a recommended practice here?
