  • Developed android application cannot connect to phpmyadmin

    - by user1850936
    I am developing an app with eclipse. I tried to store the data that key in by user into database in phpmyadmin. Unfortunately, after the user has clicked on submit button, there is no response and data is not stored in my database. Here is my java file: import java.util.ArrayList; import java.util.List; import org.apache.http.NameValuePair; import org.apache.http.message.BasicNameValuePair; import org.json.JSONObject; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.RadioButton; import android.content.res.Configuration; public class UserRegister extends Activity { JSONParser jsonParser = new JSONParser(); EditText inputName; EditText inputUsername; EditText inputEmail; EditText inputPassword; RadioButton button1; RadioButton button2; Button button3; int success = 0; private static String url_register_user = "http://10.20.92.81/database/add_user.php"; private static final String TAG_SUCCESS = "success"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_user_register); inputName = (EditText) findViewById(R.id.nameTextBox); inputUsername = (EditText) findViewById(R.id.usernameTextBox); inputEmail = (EditText) findViewById(R.id.emailTextBox); inputPassword = (EditText) findViewById(R.id.pwTextBox); Button button3 = (Button) findViewById(R.id.regSubmitButton); button3.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { String name = inputName.getText().toString(); String username = inputUsername.getText().toString(); String email = inputEmail.getText().toString(); String password = inputPassword.getText().toString(); if (name.contentEquals("")||username.contentEquals("")||email.contentEquals("")||password.contentEquals("")) { AlertDialog.Builder builder = new AlertDialog.Builder(UserRegister.this); builder.setMessage(R.string.nullAlert) .setTitle(R.string.alertTitle); builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { } }); AlertDialog dialog = builder.show(); } // creating new product in background thread RegisterNewUser(); } }); } public void RegisterNewUser() { try { String name = inputName.getText().toString(); String username = inputUsername.getText().toString(); String email = inputEmail.getText().toString(); String password = inputPassword.getText().toString(); // Building Parameters List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("name", name)); params.add(new BasicNameValuePair("username", username)); params.add(new BasicNameValuePair("email", email)); params.add(new BasicNameValuePair("password", password)); // getting JSON Object // Note that create product url accepts POST method JSONObject json = jsonParser.makeHttpRequest(url_register_user, "GET", params); // check log cat for response Log.d("Send Notification", json.toString()); success = json.getInt(TAG_SUCCESS); if (success == 1) { // successfully created product Intent i = new Intent(getApplicationContext(), StudentLogin.class); startActivity(i); finish(); } else { // failed to register } } catch (Exception e) { e.printStackTrace(); } } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); } } my php file: <?php $response = array(); require_once __DIR__ .

  • Using Forms authentication with remote auth system?

    - by chobo
    I am working on a website that uses a remote websites database to check for authentication (they are both share some database tables, but are separate website...) Right now I check the username and password against the remote websites account / member table, if there is a match I create a session. Questions: Is this secure? On authenticated pages I just check if a session of a specific type exists.Is it possible for someone to create an empty session or something that could bypass this? Is it possible to use Forms authentication with this setup? Right now if a user is authenticated I just get an object back with the username, email and id.

  • Anonymous users support vs Google bot

    - by Andy
    I have a User class in my web app that represents a user currently logged in. Every time a user vists a page, a User instance is populated based on authentication data supplied in cookies. A User instance is created even if an anonymous user logs in - and a corresponding new record is created in the User table in the database. This approach allows me to save some state info for the current user regardless of its type. The problem however with this approach is the Google bot, and other non-human web organisms crawling my pages. Every time a bot starts to walk around the site, thousands of useless records will be created in the database, each of them only to be used for a single page. Question: what is the best trade off? How to support anonymous users, save their state, and don't get too much overhead because of cookieless bots?

  • db2 jdbc driver does not release table locks

    - by as
    situation: We have a web service running on tomcat accessing DB2 database on AS400, we are using JTOPEN drivers for JNDI connections handled by tomcat. For handling transactions and access to database we are using Spring. For each select system takes JDBC connection from JNDI (i.e. from connection pool), does selection, and in the end it closes ResultSet, Statement and releases Connection in that order. That passes fine, shared lock on table dissappears. When we want to do update the same way as we did with select (exception on ResultSet object, we don't have one in such situation), after releasing Connection to JNDI lock on table stays. If we put maxIdle=0 for number of connections in JNDI configuration, this problem disappears, but this degrades performances, we have cca 100 users online on that service, we need few connections to be alive in pool. What do you suggest?

  • Does Postgresql varchar count using unicode character length or ASCII character length?

    - by bennylope
    I tried importing a database dump from a SQL file and the insert failed when inserting the string Mér into a field defined as varying(3). I didn't capture the exact error, but it pointed to that specific value with the constraint of varying(3). Given that I considered this unimportant to what I was doing at the time, I just changed the value to Mer, it worked, and I moved on. Is a varying field with its limit taking into account length of the byte string? What really boggles my mind is that this was dumped from another PostgreSQL database. So it doesn't make sense how a constraint could allow the value to be written initially.

  • What is the correct connection string for SQL 2000 server in entity framework

    - by M-Askman
    I success to use entity framework for MySQL but reverse code can not be used with SQL Server 2000, then i guess to change connection string to connect SQL Server 2000, however, got error <add name="BetterContext" connectionString="Data Source=server2;Initial Catalog=GoodDB;User ID=sa;Password=hello;MultipleActiveResultSets=True;" providerName="System.Data.SqlClient" /> An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct public partial class BetterContext : DbContext { static BetterContext() { Database.SetInitializer<BetterContext>(null); } public livefeedContext() : base("Name=BetterContext") { }

  • Entering Complex Data into Access

    - by DataMakesMeCrazy
    Fairly new to Access and trying to do something that seems simple, but may be very complex. I want to create a database of projects, each project has several phases (ie proposal, marketing, etc) and that will allow for multiple employees to work on a single project. Ie Bob and John are working on project number 102. From here, i would like to enter the forecasted start and end dates for each phase of the project, and enter the forecasted number our hours each employee will be allowed to work on that phase of that project ie. Project - Employee - Phase - Start - End - (list weeks) 102 - Bob - Marketing - 12-May-10 - 21-May-10 - 3 - 5 (3 hours first week, 5 hours the second) and so on Basically would all this data be on one table, or several? And can access dynamically show the weeks between the start and end date so that i can input the hours? I feel this database will become severely complicated :S Thanks, J

  • What's the difference between /123 and /?123?

    - by BoltClock
    I've noticed that some sites (including http://jobs.stackoverflow.com) have query strings that look like this: http://somewebapp.example/?123 as compared to: http://somewebapp.example/123 or http://somewebapp.example/id/123 What are the reasons that developers choose to implement their web apps' URLs using the first example instead of the second and third examples? And as a bonus, how would one implement the first example in PHP, given that 123 is the primary key of some row in a database table? (I just need to know how to retrieve 123 from the URL; I already know how to query the database for a primary key of 123.)

  • Is it a good practice to create a reference to application context and use it anywhere?

    - by kknight
    I have to use context in many places of my code such as database operations, preference operations, etc. I don't want to pass in context for every method. Is it a good practice to create a reference to application context at the main Activity and use it anywhere such as database operations? So, I don't need some many context in method parameters, and the code can avoid position memory leak due to use of Activity Context. public class MainActivity extends Activity { public static Context s_appContext; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); s_appContext = this.getApplicationContext();

  • Passing extended parameter into Sql 2008 connection string

    - by Pita.O
    Hi, I have a need to support extensive auditing capabilities for a system backing into Sql Server 2008. Since I plan to use LINQ (with no Stored Procs), the database would be a clean, zero contact data repository. However, I need to pratically record a snapshot of every change that happens in the db. So, I thought I should use triggers. But then, I need a user id for the particular user (not the connection string user id) to flow through into the database. In oracle, I should have been able to set up a PROXY USER and the trigger would be able to pick that up. Last I checked, there was no proxy user concept in Sql Server. Does anyone know if there's any extender property I can use to flow through my authenticated user name? ps: I don't mind the impact on connection pooling (if any). Thanks. P

  • Command Query Separation validating for retries

    - by Neil Barnwell
    So I'm comfortable with the basic concept of CQS, where you might have a command that writes to one database, and that updates the query database that you read from. However, consider the scenario where you are entering data, and want to prevent duplicates. Using new employee data entry an employee register as an example, working through a pile of application forms to key in the new employees' details: Take top sheet. Key in employee name and unique payroll number to UI. Submit. Put paper in "completed pile". Repeat. How would you now prevent the user from keying in the same payroll number again, say for instance if they get distracted and can't remember whether they've keyed one in already and the "message" hasn't got all the way back to the query db for the user to search?

  • Filemaker XSL 20sec Query Latency

    - by Ian Wetherbee
    I have an ASP frontend that loads data from a Filemaker database using XSL to perform simple queries. The problem is that the first page load takes 20 seconds +/- 200ms, then the next few page refreshes within a minute of the first request take <200ms, then the cycle starts over again. Each page load makes only 2 XSL queries, and they execute fast after the first page load, so what is causing the delay on the first page load? I have caching turned up with a 100% hit rate, and number of connections at 100. I've tried with XSL database sessions on and off, and session time anywhere from 1 to 60 minutes without any changes. The XSL loads from ASP use a GET request and add a Basic Authorization header to authenticate each time. During fast page requests, the fmserver.exe and fmswpc.exe processes don't even flinch, but during a 20 second holdup I see fmserver jump to 30% CPU and a 3mb I/O read a few seconds into the request, and occasionally fmswpc jump to 60% CPU.

  • Why Hibernates ignores the name attribute of the @Column annotation?

    - by svachon
    Using Hibernate 3.3.1 and Hibernate Annotations 3.4, the database is DB2/400 V6R1, running that on WebSphere 7.0.0.9 I have the following class @Entity public class Ciinvhd implements Serializable { @Id private String ihinse; @Id @Column(name="IHINV#") private BigDecimal ihinv; .... } For reasons I can't figure, Hibernate ignores the specified column name and uses 'ihinv' to generate the SQL: select ciinvhd0_.ihinse as ihinse13_, ciinvhd0_.ihinv as ihinv13_, ... Which of course gives me the following error: Column IHINV not in table CIINVHD Did anyone had this problem before? I have other entities that are very alike in the way that they are using # in their database field names and that are part of the PK and I don't have this problem with them.

  • Improving MySQL Update Query Efficiency

    - by Russell C.
    In our database tables we keep a number of counting columns to help reduce the number of simple lookup queries. For example, in our users table we have columns for the number of reviews written, photos uploaded, friends, followers, etc. To help make sure these stay in sync we have a script that runs periodically to check and update these counting columns. The problem is that now that our database has grown significantly the queries we have been using are taking forever to run since they are totally inefficient. I would appreciate someone with more MySQL knowledge than myself to recommend how we can improve it's efficiency: update users set photos=(select count(*) from photos where photos.status="A" AND photos.user_id=users.id) where users.status="A"; If this were a select statement I would just use a join but I'm not sure if that is possible with update. Thanks in advance for your help!

  • Why does tokyo tyrant slow down exponentially even after adjusting bnum?

    - by HenryL
    Has anyone successfully used Tokyo Cabinet / Tokyo Tyrant with large datasets? I am trying to upload a subgraph of the Wikipedia datasource. After hitting about 30 million records, I get exponential slow down. This occurs with both the HDB and BDB databases. I adjusted bnum to 2-4x the expected number of records for the HDB case with only a slight speed up. I also set xmsiz to 1GB or so but ultimately I still hit a wall. It seems that Tokyo Tyrant is basically an in memory database and after you exceed the xmsiz or your RAM, you get a barely usable database. Has anyone else encountered this problem before? Were you able to solve it?

  • C# Threading and Sql Connections

    - by Jonathan M
    I have a method that attempts to update a sql server database in an ASP.NET application. If the update fails, it catches the exception and then queues the update in MSMQ, and then spins up a new thread that will later de-queue the pending update and try again. When the thread starts, it fails to open a database connection because it is attempting to connect using Network Service as the login. The sql connection is using Windows Authentication, and will work outside of the thread. If I put a breakpoint in the code that executes inside the new thread and check the Thread.CurrentPrincipal, it shows the Identity as being the correct user. Why is the sql connection attempting to be opened by the Network Service account? I can elaborate further is necessary. Thanks.

  • How to modify the Title Bar text for SQL Server Management Studio?

    - by DaveDev
    Sometimes I keep multiple instances of SQL Server Management Studio 2005 open. I might have the dev database open in one, and the production database open in another. These appear in the Windows task bar with the text "Microsoft SQL Serve...", which means it's impossible to differentiate between them unless I open the window and scroll the Object Explorer up to see what server the window is actually connected to. Is ther any way that I can get the window to display the server name first, and then the name of the application? Like "Dev-DB.database_name - Microsoft SQL Serve..." or whatever?

  • Can a MAC address be used as a reliable part of a rights management (DRM) scheme?

    - by Jarrod Mosen
    We're currently writing some software that we want to protect. We thought that registering a user's MAC address in a database upon activation of the software seemed viable; we can profile and grab that with a Java applet, (is there a better way?) so getting it isn't too much of a problem. However, we want their computer to only run the application, and download application files/updates from the server when their MAC address has been verified with their one on-file. We understand that this means a lockdown to one computer, but special changes can be made on request. What would be the best way to verify their MAC address, to see if it exists in the database, and then serve them the files to run the application? (And to simply run it on subsequent requests, to prevent re-downloading.)

  • passing something from child form to parent
