• Possible to get PrimayKey IDs back after a SQL BulkCopy?

  - by chobo2

  Hi I am using C# and using SqlBulkCopy. I have a problem though. I need to do a mass insert into one table then another mass insert into another table. These 2 have a PK/FK relationship. Table A Field1 -PK auto incrementing (easy to do SqlBulkCopy as straight forward) Table B Field1 -PK/FK - This field makes the relationship and is also the PK of this table. It is not auto incrementing and needs to have the same id as to the row in Table A. So these tables have a one to one relationship but I am unsure how to get back all those PK Id that the mass insert made since I need them for Table B.

• Integrating TFS and MySQL

  - by user294043

  We are developing an application with Visual Studio 2008 and TFS. Our database is a MySQL DB. As we develop we keep the new queries that need to be applied to the database of our new release as the New Version Update Queries. Right now I'm keeping them in a simple text file (which is a painful task!). I know that TFS integrates with MSSQL and makes this job very easy. I've already asked our consultant from Microsoft if there is any way to integrate TFS and MySQL, and his answer was "NO". So I was wondering if anyone knows any smart way of handling this issue?

• Singletons and other design issues

  - by Ahmed Saleh

  I have worked using different languages like C++/Java and currently AS3. Most applications were computer vision, and small 2D computer games. Most companies that I have worked for, they use Singletons in a language like AS3, to retrieve elements or classes in an easy way. Their problem is basically they needs some variables or to call other functions from other classes. In a language like AS3, there is no private constructor, and they write a hacky code to prevent new instances. In Java and C++ I also faced the situation that I need to use other classe's members or to call their functions in different classes. The question is, is there a better or another design, to let other classes interact with each others without using singletons? I feel that composition is the answer, but I need more detailed solutions or design suggestions.

• Is it a good idea to use .Net for commercial software?

  - by user146780

  I was playing around with .Net reflector today and realized that Miicrosoft's entire Expression suite is written in .Net. As a result I was pretty much able to see the underlying code for expression. This makes it far easier than binary to break copy protection. I think that that's a big deal. Is it generally recommended to make commercial software in .Net where it is fairly easy to see the source code down to the variable names? I was surprised that Microsoft didn't at least dotfescate it. Thanks

• Blackberry license screen agreement like Facebook

  - by Dachmt

  Hi, I have a "basic" license agreement screen for now, a Screen with a title set and vertical field containing a textfield, separatorfield and then 2 buttons (accept or decline). The license is pretty long, it's annoying going all the way down (except with the storm it's pretty easy) and I want a kind of popup screen showing the license and the 2 buttons at the bottom. To give you an example, the exact SAME as the Facebook or App World application's license screen agreement! When you scroll the text, it's going a lot faster and it's visualy great. Thank you!

• add several variables to dataframe, based on vector

  - by Andreas

  I am sure this is easy - but I can't figure it out right now. Basically: I have a long vector of variables: names <- c("first","second", "third") I have some data, and I now need to add the variables. I could do: data$first <- NA But since I have a long list, and I would like an automated solution. This doesn't work. for (i in 1:length(names)) (paste("data$", names[i],sep="") <- NA) The reason I want this, is that I need to vertically merge to dataframes, where one doesn't have all the variables it should have. Thanks in advance

• Is it OK to put link to SO questions in a program comments?

  - by WizardOfOdds

  In quite some codebase you can see comments stating things like: // Workaround for defect 'xxx', (See bug 1434594 on Sun's bugparade) So I've got a few questions, but they're all related. Is it OK to put link to SO questions in a program's comments: // We're now mapping from the "sorted-on column" to original indices. // // There's apparently no easy way to do this in Java, so we're // re-inventing a wheel. // // (see why here, in SO question: http://stackoverflow.com/questions/951848) Do you do it? And what are the drawbacks in doing so? (see my first comment for a terrible drawback)

• JSP template inheritance

  - by Ryan

  Coming from a background in Django, I often use "template inheritance", where multiple templates inherit from a common base. Is there an easy way to do this in JSP? If not, is there an alternative to JSP that does this (besides Django on Jython that is :) base template <html> <body> {% block content %} {% endblock %} </body> <html> basic content {% extends "base template" %} {% block content %} <h1>{{ content.title }} <-- Fills in a variable</h1> {{ content.body }} <-- Fills in another variable {% endblock %} Will render as follows (assuming that conten.title is "Insert Title Here", and content.body is "Insert Body Here") <html> <body> <h1>Insert title Here <-- Fills in a variable</h1> Insert Body Here <-- Fills in another variable </body> <html>

• Limit number of views per day in Django

  - by ariddell

  Is there an easy way to limit the number of times a view can be accessed by a given IP address per day/week? A simplified version of the technique used by some booksellers to limit the number of pages of a book you can preview? There's only one view that this limit need apply to--i.e. it's not a general limit--and it would be nice if I could just have a variable overlimit in the template context. The solution need not be terribly robust, but limiting by IP address seemed like a better idea than using a cookie. I've looked into the session middleware but it doesn't make any references to tracking IP addresses as far as I can tell. Has anyone encountered this problem?

• Haskell map function with predicate

  - by Paul

  I feel like this should be fairly obvious, or easy, but I just can't get it. What I want to do is apply a function to a list (using map) but only if a condition is held. Imagine you only wanted to divide the numbers which were even: map (`div` 2) (even) [1,2,3,4] And that would give out [1,1,3,2] since only the even numbers would have the function applied to them. Obviously this doesn't work, but is there a way to make this work without having to write a seperate function that you can give to map? Filter is almost there, except I also want to keep the elements which the condition doesn't hold for, and just not apply the function to them. Thanks

• Which Ipod touch generation should I buy? 2nd or 3rd?

  - by kukabunga

  I want to create games for Iphone/Ipod touch. Unfortunately I don't have a lot of money so I can buy only one device. Ipod is cheaper than Iphone, so I decided to bought Ipod touch. But I am afraid of buying 3rd generation - because it has more memory, more faster CPU, etc. And I think if I post my app on appstore - people with 2nd generation Ipod might have trouble with my app (because I was testing it on 3rd generation). But on the other hand - I am planning to create 3d/cpu demanding game - and it would be easy for me to implement it on device with more calculation power... What should I do in this situation? Any advice is appreciate.

• C# convert integer to hex and back again

  - by codette

  How can I convert the following? 2934 (integer) to B76 (hex) Let me explain what I am trying to do. I have User IDs in my database that are stored as integers. Rather than having users reference their IDs I want to let them use the hex value. The main reason is because it's shorter. So not only do I need to go from integer to hex but I also need to go from hex to integer. Is there an easy way to do this in C#?

• Bootstrap Modal & rails remote

  - by Kevin Brown

  Using this bootstrap modal extension and animate.css for fun, how can I take a make an easy ajax modal using :remote => true to fill in the modal box? Also, how would I use the bootstrap modal default "submit/cancel" buttons to interact with a form that's loaded? I'm looking for a more dynamic solution instead of hard-html-ing every modal into the page or using a bunch of jquery ajax calls for each dialog. I've done a few quick searches, but they've turned up nil for this particular solution.

• PHP Redirect one page to another server without showing URL

  - by gav

  Having just written the title for this question I am aware of how dodgy it sounds! I am writing a back end for storing volunteer information for some friends, they have their own website to which I can add a volunteer.php page. What I want is for that page to redirect to a page on my server showing the form for the users to fill in, I would prefer the ugly URL of my site not to show. Is there an easy way to do this? Load the page inside the remotely hosted page somehow? Thanks, Gav

• Running rspec against multiple targets

  - by kaerast

  I've written an rspec test using Watir against a web application and it's running fine. However, I now want to be able to run this test against the web application running on different domain names. My initial thought was that I'd be able to pass a value to spec at the command line to set a variable within my script, but I can't see any easy method of doing this. So my second thought was that I might need to add an array of domains into my script and have it test all of them - but I don't always want to test every domain, and the domains are constantly changing as we add and remove sites to be tested. What are my options for allowing the choice of targets I want?

• Get the last N rows in the database in order?

  - by Kristopher

  Let's say I have the following database table: record_id | record_date | record_value -----------+-------------+-------------- 1 | 2010-05-01 | 195.00 2 | 2010-07-01 | 185.00 3 | 2010-09-01 | 175.00 4 | 2010-05-01 | 189.00 5 | 2010-06-01 | 185.00 6 | 2010-07-01 | 180.00 7 | 2010-08-01 | 175.00 8 | 2010-09-01 | 170.00 9 | 2010-10-01 | 165.00 I want to grab the last 5 rows with the data ordered by record_date ASC. This is easy to do with: SELECT * FROM mytable ORDER BY record_date ASC LIMIT 5 OFFSET 4 Which would give me: record_id | record_date | record_value -----------+-------------+-------------- 6 | 2010-07-01 | 180.00 7 | 2010-08-01 | 175.00 3 | 2010-09-01 | 175.00 8 | 2010-09-01 | 170.00 9 | 2010-10-01 | 165.00 But how do I do this when I don't know how many records there are and can't compute the magic number of 4? I've tried this query, but if there are less than 5 records, it results in a negative OFFSET, which is invalid: SELECT * FROM mytable ORDER BY record_date ASC LIMIT 5 OFFSET (SELECT COUNT(*) FROM mytable) - 5; So how do I accomplish this?

• What Kind of Knowledge is Necessary For a Permon Who Does Not Have IT Background? [closed]

  - by skyflyer

  One of my colleagues joined our company, which by the way is a internet company, months ago as an on-line marketing specialist. He majored English in his college and has never deeply touched IT before. He says that to be a good on-line marketing specialist he needs to lean some basic IT skills in order to deliver superb work. According to him, things like Search Engine Optimization, monitoring competitors' web sites, design some functionality on web site and so on require IT entree-level knowledge. And he asks me what kind knowledge is helpful for him to do his job. I am stunted by his question. It is easy enough to answer, things like HTML, CSS, even Photo-shop are required in some job descriptions. Also, I believe some basic understanding of dynamic web site, static web site is helpful to him. On the other hand, as a techie I still feel my answer is awkward. What is your opinion on this? Always lot of thanks to you guys on SO.

• List replies in a winform

  - by andrew

  In my C# app I get an xml from a server that contains some replies like in a forum thread (with elements like author, time, body, title, whatever). When I get this xml, I create a new form in which i want to display these replies, and a little text box with an "add reply" button. I'd also like some edit buttons on perhaps my own replies in the reply list displayed in the form. The simplest way that came to my mind to display the replies is to put a web browser control in the form, generate a full html page in a string from the xml, and throw it in that web browser control. And under it i can put the text box with the add reply button. Everything is ok, except that i have no idea of how i could implement the edit function on my own replies (i mean i could add a link in there... but link to what) I would like to know if there is a way to get that edit event from the web browser control (my guess is i can't) or another (maybe simple/easy) idea of displaying the replies in a winform using other controls

• Redirected wikipedia request

  - by Le_Coeur

  Hi people, i need to write a program, that can redirect's http://localhost:8080 to en.wikipedia.org, it seems to be easy, but i have some problems(only with wikipedia with another sites works good). I make url to wikipedia: URL url = new URL("http", "en.wikipedia.org", 80, "/wiki"); than URLConnection, extract headers, and when i want connection.getInputStream(), i received message 404 Not Found. So i have tried some hack for host header, because in this way host header is localhost:8080, therefor i have tried to change host header to wikipedia, and it works, but after request in browser http://localhost:8080 wikipedia opens, but url in browser changes to en.wikipedia.org, but i want proceed with localhost :)

• How to make Subversion use Linux system accounts for authentication?

  - by Alejandro García Iglesias

  Hi all, I've set up a Ubuntu Server for Subversion with Apache/WebDAV interface to share repositories with other developers. My question is, how can I make Subversion use the linux system accounts for authentication? This would lead to very easy Subversion account management. Subversion with Apache/WebDAV is currently working with this configuration: Contents of /etc/apache2/mods-available/dav_svn.conf: <Location /svn> DAV svn SVNParentPath /home/svn SVNListParentPath On AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/apache2/dav_svn.passwd Require valid-user </Location> I have tried changing AuthUserFile /etc/apache2/dav_svn.passwd with AuthUserFile /etc/shadow with no success. This makes the server to respond with a error 500 internal server error. It's logical, why the Web service should have access to system authentication file? Thanks a lot in advance!

• How do I let a user sign in from a different domain on Authlogic?

  - by Newy

  [This is slightly different than a previous question about having multiple domains share the same cookie. It seemed like there wasn't an easy way to do that.] I have a application at application.com. A customer has app.customer.com pointed at my site on Heroku, and I have everything set up so that it renders a specific version of app correctly. The issue is that I want a user at app.customer.com to be able to login. I believe authlogic is now setting the cookie on application.com, so while it verifies the credentials, no session on customer.com is ever created.

• Finding the right version of the right JAR in a maven repository

  - by Matt McHenry

  I'm converting a build that has 71 .jar files in its global lib/ directory to use Maven. Of course, these have been pulled from the web by lots of developers over the past ten years of this project's history, and weren't always added to VCS with all the necessary version info, etc. Is there an easy, automated way to go from that set of .jar files to the corresponding <dependency/> elements for use in my pom.xml files? I'm hoping for a web page where I can submit the checksum of a jar file and get back an XML snippet. The google hits for 'maven repository search' are basically just finding name-based searches. And http://repo1.maven.org/ has no search whatsoever, as far as I can see. Update: GrepCode looks like it can find projects given an MD5 checksum. But it doesn't provide the particular details (groupId, artifactId) that Maven needs.

• How to push text from one UITextfield to another UITextfield in the next View? And back!?

  - by Chrizzz

  an Hi, I have an UITextField in one view, UITextField A in View A. And I have another in view B, UITextField B in View B. I use a Navigation Controller Bar to switch between the views. The UITextFields are properties and connected Outlets of both views A and B. On my view A there is an "Options"-button which pushes view B. So when you are typing in Textfield A, I would like the same text to appear in Textfield B. When you edit TextField B and you go back to view A (via the "Title View A"-button in de navigation bar), I would like the same text to re-appear in Textfield A. I expected this to be easy. But I can't get it working. I tried: ViewBController *controller = [[ViewBController alloc] initWithNibName:@"ViewBController" bundle:nil]; controller.TextFieldA.text = TextFieldB.text But nothing appeared in view B. And how do I get back? I dont want to use NSUserdefaults because I would have to remove the values also.

• Why is there so much poorly indented code out there?

  - by dsimcha

  The more I browse the code to open source projects in languages that aren't Python, the more I realize that it seems a lot of programmers don't believe in proper indentation. (I won't mention any projects specifically to avoid having anyone take this question too personally.) Usually code is indented, but in a way just different enough from the standard style that it drives me crazy, especially in old/crufty code. I've noticed that when I write in C-like languages, I tend to indent correctly as religiously as when I'm writing in Python, with the exception of debugging code that I actually want to stick out like a sore thumb. Given how easy it is with a modern IDE to fix incorrect indentation, what are some rationales for not religiously keeping indentation in sync with braces?
