• MDE Access decrypt JDBC

  - by michelemarcon

  I want to perform JDBC SQL queries on a MDE Access file. I've set up the data source ODBC and everything worked well for a MDE file. Now, I'm working with a newer version of the MDE file, and here is the result: java.sql.SQLException: [Microsoft][Driver ODBC Microsoft Access] Cannont read record. Read authorization unavailable for "tbl_mytable". If I open the MDE with Access Runtime I am asked for a password, and after leaving a blank password I can see all the data. Of course, "tbl_mytable" does exist inside the database.

• Interviewing - convincing young interviewers that my experience matters [closed]

  - by ritu

  As requested, I split this question from a two part question I asked at http://stackoverflow.com/questions/2482071/modern-web-development-general-question My question is how do i convince the young programmers who interview me that my years of system programming experience, MFC, Win32 programming are still relevant and I should not be automatically rejected because I don't know the differences between Drupal and <pick your technology>. It seems like I can ask a dozen question that these guys won't be able to answer but somehow because I don't know the latest fad counts against me. I do read, but if you don't use what you read in your daily work, you will never have expert knowledge of it. So bottom line: is the only way for me to take a .NET or Java job is for me to start at the bottom all over?

• Can you recommend a .net template engine?

  - by serg10

  I am looking for a .net templating engine - something simple, lightweight, stable with not too many dependencies. All I need it for at the moment is creating templated plain text and html emails. Can anyone give me a good recommendation? If it helps at all - something like Java's Freemarker or Velocity libraries. [UPDATE] Thanks for the answers so far - much appreciated. I am really intested in recommendations or war stories from when you have used these libraries. Seems to be the best way to make a decision without trying each in turn.

• asp.net mvc deployment

  - by Casey

  I've been dealing with a legacy asp.net 2.0 web site that was originally setup to deploy everything (source uncompiled) to the target server. I've been looking at doing some major upgrades and want to move to asp.net mvc. I'm coming from mostly a Java background where we typically deploy everything inside of a Web ARchive (war file) and the application server takes it from there. Is there a similar concept in the .net world? Right now in my mvc test app, I just put the compiled code into the deployed bin folder and the rest of the script/view files there as well. From what I have been reading it seems that most use the Publish feature of VS.

• Teach Perl as a first language?

  - by yossale

  I need to teach a non-programmer the basics of computer programming + some basic programming skills (- He's going to be in a position between the clients and the programmers , so the company requires him to learn the basic concepts of programming). I thought of Perl - You can teach it without getting into typing and pointers and it's syntax is very close to human (precious "bless" :) ) - but I'm a bit troubled because I feel like I'm going to "spoil" him for other languages in the future (C,C++,Java - What some people call "Real" languages) - exactly because of the reasons mentioned above. What do you think?

• Android and Protocol Buffers

  - by spaceboy2000

  I am writing an Android application that would both store data and communicate with a server using protocol buffers. However, the stock implementation of protocol buffers compiled with the LITE flag (in both the JAR library and the generated .java files) has an overhead of ~30 KB, where the program itself is only ~30 KB. In other words, protocol buffers doubled the program size. Searching online, I found a reference to an Android specific implementation. Unfortunately, there seems to be no documentation for it, and the code generated from the standard .proto file is incompatible with it. Has anyone used it? How do I generate code from a .proto file for this implementation? Are there any other lightweight alternatives?

• Do Scala and Erlang use green threads?

  - by CHAPa

  I've been reading a lot about how Scala and Erlang does lightweight threads and their concurrency model (actors). However, I have my doubts. Do Scala and Erlang use an approach similar to the old thread model used by Java (green threads) ? For example, suppose that there is a machine with 2 cores, so the Scala/Erlang environment will fork one thread per processor? The other threads will be scheduled by user-space (Scala VM / Erlang VM ) environment. Is this correct? Under the hood, how does this really work?

• Execute PHP without leaving page

  - by Dylan Taylor

  Okay. I have a form - textarea (named "su") and submit button. When the form is submitted, I need to run a PHP script without refreshing/leaving page "echo" or somehow print a return on the screen I'm pretty sure this works via some kind of ajax request thing. but I have no idea what I'm talking about. I'm not big on ajax or javascript, but this is a function i use very frequently and I'd like to learn how it works so I can implement it when i need to now and in the future. Like i said I'm uneducated with ajax or java. a quick example would be wonderful. thanks for taking the time to read!

• Fire Fox 3.6 - location.href not working in JSP

  - by user299873

  I have jsp page with method = POST and action='/mydir/mypage/nextpage' I have a button : < button title='Continue' onclick="this.form.perform.value='cancelButton'; javascript:doCloseWindow();" Continue < /button and java script method like: function doCloseWindow(){ location.href = "https://abc.xyz.com/mydir/?param=123"; } It does not work in fire fox 3.6. On click of button; it redirects to the path I mentioned in form action. With Tamper data I find that the request goes to URL ( as in method ) with GET and then it re-directs to form's action URL. I added return false in the method call also.-- javascript:doCloseWindow();return false" I tired various combination like window.location.href = "https://abc.xyz.com/mydir/?param=123"; window.document.location.href = "https://abc.xyz.com/mydir/?param=123"; document.location.href = "https://abc.xyz.com/mydir/?param=123"; But no success.

• Are All Dynamic Languages Typo-friendly?

  - by yar

  With Java on one side and Ruby/Groovy on the other, I know that in the second camp I'm free to make typos which will not get caught until run-time. Is this true of all dynamically-typed languages? Edit: I've been asked to elaborate on the type of typo. In Ruby and in Groovy, you can assign to a variable with an accidental name that is never read. You can call methods that don't exist (obviously your tests should catch this, it's been said). You can refer to classes that don't exist, etc. etc. Basically any valid syntax, even with typographical errors, is valid in both Ruby and Groovy.

• M2Eclipse and EAR projects on Weblogic

  - by Steve

  How can I import a maven EAR project into Eclipse 3.4, and be able to use the IDE (WTP) to deploy the ear successfully to Weblogic (9.2)? The main issue is that the dependent jars are not being included in the ear (under APP-INF/lib) when it gets deployed through the IDE. When I build from command line, the ear is exactly how I want it. I am using the APP-INF/lib configuration for the ear plugin, and have included the jarModule sections for all the required jars. When editing the eclipse EAR project's Java EE components, all the jars are listed, but not in the APP-INF/lib. Only when I open a dependent jar project do those specific jars get set under that subfolder. All the 3rd party jars are showing they will end up in the wrong place. If you need more info, just let me know. Thanks!

Is just an webView that loads html5, css and java script or is much more than that?

• populate a comboBox in Griffon App dynamically

  - by kulkarni

  I have 2 comboBoxes in my View of Griffon App (or groovy swingBuilder) country = comboBox(items:country(), selectedItem: bind(target:model, 'country', value:model.country), actionPerformed: controller.getStates) state = comboBox(items:bind(source:model, sourceProperty:'states'), selectedItem: bind(target:model, 'state', value:model.state)) The getStates() in the controller, populates @Bindable List states = [] in the model based on the country selected. The above code doesn't give any errors, but the states are never populated. I changed the states from being List to a range object(dummy), it gives me an error MissingPropertyException No such property items for class java.swing.JComboBox. Am I missing something here? There are a couple of entries related to this on Nabble but nothing is clear. The above code works if I had a label instead of a second comboBox.

• Python: Define Classes in Packages

  - by rfkrocktk

  I'm learning Python and I have been playing around with packages. I wanted to know the best way to define classes in packages. It seems that the only way to define classes in a package is to define them in init.py of that package. Coming from Java, I'd kind of like to define individual files for my classes. Is this a recommended practice? I'd like to have my directory look somewhat like this: recursor/ __init__.py RecursionException.py RecursionResult.py Recursor.py So I could refer to my classes as "recursor.Recursor," "recursor.RecursionException," and "recursor.RecursionResult.py". Is this "do-able" or recommended in Python?

• ASP.net Pop up Alert without page load

  - by Sunny

  Hi, In ASP.NET -- I want to popup an alert window in the case of an event. I don't have a button, i do not load the page at that event. When I searched i got a lot of java script examples but I can't use them as they work either on a button click or on page load. I just want a pop window to come as soon as I capture a particular event. I keep checking for the events every 5 second, as soon as i capture one event, there is a switch case for the actions to follow according to the event captured. For one particular case, i need one pop up "Sorry" along with an OK button. Can someone tell me what to do. Thanks

• What's the easiest way to parse numbers in clojure?

  - by Rob Lachlan

  I've been using java to parse numbers, e.g. (. Integer parseInt numberString) Is there a more clojuriffic way that would handle both integers and floats, and return clojure numbers? I'm not especially worried about performance here, I just want to process a bunch of white space delimited numbers in a file and do something with them, in the most straightforward way possible. So a file might have lines like: 5 10 0.0002 4 12 0.003 And I'd like to be able to transform the lines into vectors of numbers.

• All possible combinations of n items selected randomly from a set of x items (algorithm)

  - by SubPortal

  I have a set of x string items e.g("A","B","C","D","E","F") I need to know the formula that calculates how many combinations of n items and what is the algorithm that generates all possible combinations e.g if we need to select 4 items from the list randomly. those 4 items could be: ("A","B","C","D") or ("A","B","C","E") or ("A","B","C","F") or ("A","B","D","E") ...etc I need the formula that calculates how many sets of items will be generated without repetition, that is we consider ("A","B","C","D") as one of the resulted combinations we cannot consider the same items as another resultant combination with replacing the positions of the items in the set like ("A","B","D","C") Also I need the algorithm that generates all possible combinations in any programming language. [C#,VB.NET,Java,C++] Thank you for any help.

• Grafting Scala 2.8 into a Netbeans NBAndroid Project...What steps am I missing?

  - by Michael Kohout

  Hi All; Due to Apple's recent T+C hijinks, I've become interested in developing for Android. Anyways, I'm trying to get a mixed-language Android 2.1 project going in Netbeans 6.8 (with the NBAndroid 0.10 plugin). The two languages being Java and Scala(2.8 head build). To give you a basic idea of what the app does right now, it's just a simple "Hello World" app. To get this to build, I've modified the projects's build.xml file: -- -injars ${scala-library}(!META-INF/MANIFEST.MF,!library.properties) -outjars "${build.classes.dir}/classes.min.jar" -libraryjars "${file.reference.android.jar}" -dontwarn -dontoptimize -dontobfuscate -keep public class * extends android.app.Activity -keep public class scala.xml.include.sax.Main** I've gotten the project so that it'll build, but it errors on startup in my Android Emulator(inside the emulator Android tells me my application has stopped unexpectedly). So my questions are: Does anyone see what I may be doing wrong? And is there any way to get access to the logs that the emulator must create? thanks Mike Kohout

• Is there a jdbc driver for SQL Server that can search for database instances on network?

  - by djangofan

  Is there a jdbc driver for SQL Server that can search for database instances on network? Just wanting to emulate "OSQL -L" from the JDBC driver. Dont want to have to call OSQL from JNI or something. I also don't want to have to write my own code for scanning a UDP port. I want my Java application to be able to search for live SQL Servers and prompt me with a list of available servers. Isn't this a reasonable expectation for a JDBC driver? OSQL.exe can do it and so why not the JDBC driver?

• How do I display a local html file in a UIWebView?

  - by Thomas

  I have a relatively simple question that I cannot seem to find the answer for. While doing the Google Maps Java API Tutorials, I ran into a problem. I can load an HTML file from the web, but when I try it locally, it just displays the contents of the file instead of running the script. Here's what works: NSString *url = @"http://code.google.com/apis/maps/documentation/v3/examples/geocoding-simple.html"; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]]; [webView loadRequest:request]; I want to store the HTML file locally and run it from the device itself, so I tried: [webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"geocoding-simple" ofType:@"html"]isDirectory:NO]]]; and it just displayed the contents of the file. What am I doing wrong here? Thomas
