  • Combining packages from different projects into a single project in eclipse

    - by primal
    Hi, As part of the Android application I am developing in eclipse, I need to combine two packages from different projects into a single project. I tried copying the files in the package of the second project under the src folder of the first folder and copied other files required for second package into the res folder of the first project. But the auto-generated Java files i.e R.java doesn't get updated on copying. I tried right clicking on the project and clicking on Android Tools - Fix Project Properties. But nothing changed. Any pointers on what I am doing wrong much be appreciated.

  • inserting datetimes into database using java

    - by gordatron
    Hi, I am wanting to insert a datetime into a MySql data base using Java and a prepared statement: Calendar cal = Calendar.getInstance(); PreparedStatement stmnt = db.PreparedStatement("INSERT INTO Run " + "(Time) VALUE (?) "); stmnt.setDate(1, new java.sql.Date(cal.getTime())); stmnt.executeQuery(); NOTE: thre is currently an error - cannot find symbol (java.sql.Date) line 4 here db is an instance of a sort of wrapper class that exposes what I need from java.sql - its just getting a prepared statement from my connection object here. Time (the column) is a date time in my database, and I can only see sedDate and setTime method but I want to store both - also my code does not work anyway ;-) if anyone could give me some pointers on inserting a combined date time (current time would be a great help as that's my first goal) into a MySql DB using a prepared statement I would be very grateful. Thanks

Sometimes you need to do builds for live and testbeds in the same day ! Its really hard to change big project namespaces everytime you build. How can I just change the webconfig connection string and get it done? Thanks,

  • Best .NET Solution for Frequently Changed Database

    - by sestocker
    I am currently architecting a small CRUD applicaton. Their database is a huge mess and will be changing frequently over the course of the next 6 months to a year. What would you recommend for my data layer: 1) ORM (if so, which one?) 2) Linq2Sql 3) Stored Procedures 4) Parametrized Queries I really need a solution that will be dynamic enough (both fast and easy) where I can replace tables and add/delete columns frequently. Note: I do not have much experience with ORM (only a little SubSonic) and generally tend to use stored procedures so maybe that would be the way to go. I would love to learn Ling2Sql or NHibernate if either would allow for the situation I've described above.

  • SQL Database dilemma : Optimize for Querying or Writing?

    - by Harry
    I'm working on a personal project (Search engine) and have a bit of a dilemma. At the moment it is optimized for writing data to the search index and significantly slow for search queries. The DTA (Database Engine Tuning Adviser) recommends adding a couple of Indexed views inorder to speed up search queries. But this is to the detriment of writing new data to the DB. It seems I can't have one without the other! This is obviously not a new problem. What is a good strategy for this issue?

  • how do I integrate the aspnet_users table (asp.net membership) into my existing database

    - by ooo
    i have a database that already has a users table COLUMNS: userID - int loginName - string First - string Last - string i just installed the asp.net membership table. Right now all of my tables are joined into my users table foreign keyed into the "userId" field How do i integrate asp.net_users table into my schema? here are the ideas i thought of: Add a membership_id field to my users table and on new inserts, include that new field in my users table. This seems like the cleanest way as i dont need to break any existing relationships. break all existing relationship and move all of the fields in my user table into the asp.net_users table. This seems like a pain but ultimately will lead to the most simple, normalized solution any thoughts?

  • Creating a multiplatform webapp with HTML5 and Google maps

    - by Bart L.
    I'm struggling how to develop a webapp for Android and iOS. My first app was a simple todo app which was easy to test in my browser and it only used html, javascript and css. However, I have to create an app which uses Google Maps Api to get the location. I created a simple html5 page to test which places a marker on a map. It works fine when testing it on my local server. But when I create an .apk file for Android, the app doesn't work. So I'm wondering, isn't it possible to use it like this? Do I have the use the phonegap libraries to use their geolocation library? And if so, how do you handle the development of a webapp in phonegap for multiple OS? Do you have to install an Android environment and an iOS environment to each include the right phonegap library and to test them properly? Update: I use the following code on my webserver and it works perfectly. When I upload it in a zip-folder to the photogap cloud and install the APK file on my phone, it doesn't work. <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Simple Geo test</title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script> </head> <body> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script> <script> function success(position) { var mapcanvas = document.createElement('div'); mapcanvas.id = 'mapcontainer'; mapcanvas.style.height = '200px'; mapcanvas.style.width = '200px'; document.querySelector('article').appendChild(mapcanvas); var coords = new google.maps.LatLng(position.coords.latitude, position.coords.longitude); var options = { zoom: 15, center: coords, mapTypeControl: false, navigationControlOptions: { style: google.maps.NavigationControlStyle.SMALL }, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("mapcontainer"), options); var marker = new google.maps.Marker({ position: coords, map: map, title:"You are here!" }); } if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(success); } else { error('Geo Location is not supported'); } </script> <article></article> </body> </html>

  • Populating a WPF listbox with items from an SQL (SDF) database

    - by xplinux557
    I have been searching on how to do this for a very long time, and I have not managed to get a straight answer on the subject, so hopefully one of you StackOverflow users will be able to help me here. I have a WPF ListBox named CategoryList and a SDF database called ProgramsList.sdf (with two tables called CategoryList and ProgramsList). What I wish my program to do is get the category names from the CategoryList table and list them in the ListBox control called CategoryList. Here's the code that I tried, but it only caused my program to crash. SqlConnection myConnection = new SqlConnection("Data Source=" + AppDomain.CurrentDomain.BaseDirectory + "ProgramsList.sdf"); SqlDataReader myReader = null; myConnection.Open(); CategoryList.Items.Clear(); SqlDataReader dr = new SqlCommand("SELECT Name FROM CategoryList ORDER BY Name DESC", myConnection).ExecuteReader(); while (myReader.Read()) { CategoryList.Items.Add(dr.GetInt32(0)); } myConnection.Close(); Can anyone help me? Thanks in advance!

  • where to store information like gender and year of birth?

    - by fayer
    i have users and i need them to specify a gender (male, female) and year of birth (1930, 1931...1999, 2000). i wonder where i should store these values: in the database? in php file? if i store them in the database i have to manually create all entries first. but a good thing is that the user table will have constraints so the gender field will always be male or female, it cannot be something else. if i store them in the php file (eg. as html) then i can easily add/remove values. but a con is that i dont have the constraints in database, so another value could be stored as gender by mistake, even though i could add validation in php backend so even if someone hacked the html it is not stored unless it's either male or female. what is best practice to do this? thanks

  • migrate/ update core data app without erasing user data!

    - by treasure
    hello, i have a very complicated problem that i would like to share with you and maybe someone can answer it for me. before i start i have to say that i am very new in this. So, i have a coredata iphone app (much like the recipes app) that uses a pre-populated sql database. The user can add/edit his own data but the default data cannot be deleted. the useres data are ALL saved in the same sql database. QUESTION: what do i have to do in order to: - update some (not all) of the default data that are stored in the sql database without "touching" the user's data? (the model will stay the same - no new entities etc-) (if the user uninstall the app and then reinstall the new version everything will be ok but i dont want to do this, obviously). can someone PLEASE help in coding level?

  • Designing DAOs for data sources other than a database

    - by James P.
    Hi, Until now I've been used to using DAOs to retrieve information from databases. Other sources of data are possible though and I'm wondering if and how the pattern could be applied in general. For example, I'm now working on an application that fetches XML on the web. The XML file could be considered as a data source and the actual fetching is similar in principle to a database request. I'm not quite sure how the DAO could be structured though. Any views on the subject are welcome.

  • Echo html+php from database

    - by pg-robban
    I am working on a site which deals with a lot of texts in HTML, so recently I learned PHP and moved them into a MySQL database and echo the contents given a specific chapter and section. Now this works relatively fine, the HTML shows up properly. However, in some parts I have included PHP function calls, and these doesn't seem to be evaluated - rather, they get just inserted into the source code (and thus invisible for the page viewer), never doing anything. They did work when they were simple .html files. How can I solve this? For example, a text can look like this: <?php printChapterName(); ?> <p>Some text</p> ... <?php showImage($name, $alt-text); ?> ... This just shows the text on the page. Edit: The functions are echo:ing some HTML.

    - by TazMan
    I'm trying to write a process that would read data from a database and upload it onto a cloud datastore. How can I decide the partition strategy of the data? I want to query the table in chunks and process each chunk in 10 threads. Each thread basically will send the data to an individual node on a 10 node cluster on the cloud.. Where in the below multi threading code will the dataquery to extract and send 10 concurrent requests for uploading data to cloud would be? public class Caller { public static void main(String[] args) { ExecutorService executor = Executors.newFixedThreadPool(10); for (int i = 0; i < 10; i++) { Runnable worker = new DomainCDCProcessor(i); executor.execute(worker); } executor.shutdown(); while (!executor.isTerminated()) { } System.out.println("Finished all threads"); } }
