  • Best Embedded SQL DB for write performance?

    - by max.minimus
    Has anybody done any benchmarking/evaluation of the popular open-source embedded SQL DBs for performance, particularly write performance? I've some 1:1 comparisons for sqlite, Firebird Embedded, Derby and HSQLDB (others I am missing?) but no across the board comparisons... Also, I'd be interested in the overall developer experience for any of these (for a Java app).

  • Problem using generics in function

    - by JAVA
    Hi all, I have this functions and need to make it one function. The only difference is type of input variable sourceColumnValue. This variable can be String or Integer but the return value of function must be always Integer. I know I need to use Generics but can't do it. public Integer selectReturnInt(String tableName, String sourceColumnName, String sourceColumnValue, String targetColumnName) { Integer returned = null; String query = "SELECT "+targetColumnName+" FROM "+tableName+" WHERE "+sourceColumnName+"='"+sourceColumnValue+"' LIMIT 1"; try { Connection connection = ConnectionManager.getInstance().open(); java.sql.Statement statement = connection.createStatement(); statement.execute(query.toString()); ResultSet rs = statement.getResultSet(); while(rs.next()){ returned = rs.getInt(targetColumnName); } rs.close(); statement.close(); ConnectionManager.getInstance().close(connection); } catch (SQLException e) { System.out.println("???????? ?? ???? ?? ???? ?????????!"); System.out.println(e); } return returned; } // SELECT (RETURN INTEGER) public Integer selectIntReturnInt(String tableName, String sourceColumnName, Integer sourceColumnValue, String targetColumnName) { Integer returned = null; String query = "SELECT "+targetColumnName+" FROM "+tableName+" WHERE "+sourceColumnName+"='"+sourceColumnValue+"' LIMIT 1"; try { Connection connection = ConnectionManager.getInstance().open(); java.sql.Statement statement = connection.createStatement(); statement.execute(query.toString()); ResultSet rs = statement.getResultSet(); while(rs.next()){ returned = rs.getInt(targetColumnName); } rs.close(); statement.close(); ConnectionManager.getInstance().close(connection); } catch (SQLException e) { System.out.println("???????? ?? ???? ?? ???? ?????????!"); System.out.println(e); } return returned; }

  • Can you create folders to organize web sites in IIS7?

    - by MisterJames
    I have several ASP.NET sites in IIS7 and would like to be able to group them into folders (or other mechanism, if available). Ideally, I would use a customer name or account number and put the sites under there. Is there a way to customize the organization of sites in IIS7, or is there just the one 'flat' view? I'm open to tricks and hacks.

    - by Yordan Pavlov
    I am aware there are other nant and msbuild related questions on stack overflow, but I could not find a direct comparison between the two and so here is the question. When should one choose Nant over MSBuild? Which one is better for what? Is Nant more suitable for home/open source projects and MSBuild for work projects? What is your experience with any of the two?

  • Typemock - Worth the money?

    - by AngryHacker
    I know that this is a subjective question... Typemock is $799 per developer. Licences for 5 devs comes up to a pretty large sum. If someone here used Typemock and given that there are open source mocking frameworks, is it worth the money? Why?

  • Getting started with JUCE for Android

    - by steveha
    I need to start building an Android app that uses the JUCE libraries. I'm reading the web site and trying to figure stuff out. I tried installing JUCE on an Ubuntu 11.04 system, and when I built the IntroJucer app, the menus don't work right (they flash open when I click with the mouse but then disappear). Can a JUCE app for Android be built on Mac OS X, or even Windows? If you are using JUCE to build Android apps, please give me any advice you can.

  • What's the best way to run a Linux virtual server in Windows 7?

    - by Leonid Shevtsov
    I need a virtual server for web development, it'll host Apache+Postgres+Ruby+something else. What's the most effective software to run such a server? (ie with least virtualization overhead) Is there a way to run Linux as as service? I use VirtualBox at the moment, but it's inconvenient in some ways, such as it needs an emulator window open which also captures keyboard input when alttabbed into. (Also, coLinux hangs at boot on my machine, so it's probably not an option)

  • How to find which existing .NET solutions contain a project?

    - by Daniel Daranas
    I am exploring a structure of folders with C# projects such as the following: Projects ProjectA ProjectB ProjectC ProjectD Scattered around in the same folders as the .csproj files, there are several solution (.sln) files. Is there a fast way to find all the solutions that contain ProjectD.vsproj? I can open them one by one and see what they contain, but I would like a feature such as "find all the solutions containing this project".

  • Does a syntax for this exist? In any language?

    - by Michael
    It seems pretty common to me to have an argument, in a dynamically typed language that is either an Object or a key to lookup that object. For instance when I'm working with a database I might have a method getMyRelatedStuff(person) All I really need to lookup the related stuff is the id of the person so my method could look like this in python: def getMyRelatedStuff(person_or_id): id = person_or_id.id if isinstance(person,User) else person_or_id #do some lookup Or going the other direction: def someFileStuff(file_or_name): file = file_or_name if hasattr(file,'write') else open(file_or_name)

  • creating a full html file out of webloc in a batch mode

    - by Wordpress Newbie
    Hi, I've got over 400 bookmarks saved as .webloc files. I'd like to move them to the iPhone's goodReader app. goodReader cannot open webloc files. It can sork with pdf, html but not webloc. Do you know of a way or a program that would take a folder as its input, and convert every single .webloc file in it into a PDF version or a html version - so I can grab the converted files and move them onto iPhone. Thank you

  • RegCreateKeyEx - does it update the returned handle on failure?

    - by Permaquid
    MSDN documentation seems silent on whether RegCreateKeyEx ever updates the value of the handle referred to by its second-last parameter when it fails. My tests have only shown it not to update this - i.e., I set h = 0 before the call, pass &h to a call to RegCreateKeyEx to open a non-existent key, and see h = 0 after the call. Does anyone know of any situation in which the handle would be changed?

  • Determining if an Activity exists on the current device?

    - by stormin986
    Is there a way to check and see if an Activity exists on your device? If I have a youtube video link I want to specify it open in the YouTube PlayerActivity. However, I don't want to crash if for some reason they don't have it. Is there a way to check and see if the activity exists? I don't think I can catch the runtime exception since startActivity() doesn't throw it.
