  • Encoding problem (Hebrew UTF8) in WordPress

    - by Tal Galili
    Hi all, I have a blog (of a friend) I am failing to fix: http://www.nivcalderon.com/ The language of the website is Hebrew, but the encoding scrambles the output, and I can't find how to fix it. I tried changing the DB colliation to be utf8_general_ci. I added this: define('DB_COLLATE', 'utf8_general_ci'); To the wp-config (and also this: define('DB_CHARSET', 'utf8'); But removed it later, since it didn't seem to fix the problem) Any ideas of what else to do ? Thanks

  • android error NoSuchElementException

    - by Alexander
    I have returned a cursor string but it contains a delimiter. The delimiter is . I have the string quest.setText(String.valueOf(c.getString(1)));I want to turn the into a new line. What is the best method to achieve this task in android. I understand there is a way to get the delimeter. I want this to achieved for each record. I can itterate through record like so. Cursor c = db.getContact(2); I tried using a string tokenizer but it doesnt seem to work. Here is the code for the tokenizer. I tested it in just plain java and it works without errors. String question = c.getString(1); // quest.setText(String.valueOf(c.getString(1))); //quest.setText(String.valueOf(question)); StringTokenizer st = new StringTokenizer(question,"<ENTER>"); //DisplayContact(c); // StringTokenizer st = new StringTokenizer(question, "=<ENTER>"); while(st.hasMoreTokens()) { String key = st.nextToken(); String val = st.nextToken(); System.out.println(key + "\n" + val); } I then tried running it in android. Here is the error log 06-06 22:31:55.251: E/AndroidRuntime(537): FATAL EXCEPTION: main 06-06 22:31:55.251: E/AndroidRuntime(537): java.util.NoSuchElementException 06-06 22:31:55.251: E/AndroidRuntime(537): at java.util.StringTokenizer.nextToken(StringTokenizer.java:208) 06-06 22:31:55.251: E/AndroidRuntime(537): at alex.android.test.database.quiz.TestdatabasequizActivity$1.onClick(TestdatabasequizActivity.java:95) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.view.View.performClick(View.java:3511) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.view.View$PerformClick.run(View.java:14105) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.os.Handler.handleCallback(Handler.java:605) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.os.Handler.dispatchMessage(Handler.java:92) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.os.Looper.loop(Looper.java:137) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.app.ActivityThread.main(ActivityThread.java:4424) 06-06 22:31:55.251: E/AndroidRuntime(537): at java.lang.reflect.Method.invokeNative(Native Method) 06-06 22:31:55.251: E/AndroidRuntime(537): at java.lang.reflect.Method.invoke(Method.java:511) 06-06 22:31:55.251: E/AndroidRuntime(537): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 06-06 22:31:55.251: E/AndroidRuntime(537): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 06-06 22:31:55.251: E/AndroidRuntime(537): at dalvik.system.NativeStart.main(Native Method) This is the database query public Cursor getContact(long rowId) throws SQLException { Cursor mCursor = db.query(true, DATABASE_TABLE, new String[] {KEY_ROWID, question, possibleAnsOne,possibleAnsTwo, possibleAnsThree,realQuestion,UR}, KEY_ROWID + "=" + rowId, null, null, null, null, null); if (mCursor != null) { mCursor.moveToFirst(); }

Any ideas what's going on and/or how to fix it? Thanks.

  • Stack recommendations for small/medium-sized web application in Python

    - by reto
    I'm looking for some recommendations for a python web application. We have some memory restrictions and we try to keep it small and lean. We thought about using WSGI (and a python webserver) and build the rest ourself. We already have a template engine we'd like to use, but we are open for some suggestions regarding the whole request handling (the controller). The application has to run in a single process and the requests have to be processed with multiple threads. We've looked at django, but we are a not sure if it fits into our memory budget. Your feedback is very welcome! Cheers, Reto

  • C# SQL: What is the best way to implement a dynamic table?

    - by SirMoreno
    I want to allow the user to add columns to a table in the UI. The UI: Columns Name:__ Columns Type: Number/String/Date My Question is how to build the SQL tables and C# objects so the implementation will be efficient and scalable. My thought is to build two SQL tables: TBL 1 - ColumnsDefinition: ColId, ColName, ColType[Text] TBL 2 - ColumnsValues: RowId, ColId, Value [Text] I want the solution to be efficient in DB space, and I want to allow the user to sort the dynamic columns. I work on .NET 3.5 MSSQL 2008. Thanks.

  • Position of object in database

    - by fl00r
    Hi! I have got model Team and I've got (i.e.) team = Team.first :offset => 20. Now I need to get number of position of my team in db table. I can do it in ruby: Team.all.index team #=> 20 But I am sure that I can write it on SQL and it will be less expensive for me with big tables.

  • How can I compare tables in two different databases using SQL?

    - by chama
    I'm trying to compare the schemas of two tables that exist in different databases. So far, I have this query SELECT * FROM sys.columns WHERE object_id = OBJECT_ID('table1') The only thing is that I don't know how to use the sys.columns to reference a database other than the one that the query is connected to. I tried this SELECT * FROM db.sys.columns WHERE object_id = OBJECT_ID('table1') but it didn't find anything. I'm using SQL Server 2005 Any suggestions? thanks!

  • How do I read multiple lines from STDIN into a variable?

    - by The Wicked Flea
    I've been googling this question to no avail. I'm automating a build process here at work, and all I'm trying to do is get version numbers and a tiny description of the build which may be multi-line. The system this runs on is OSX 10.6.8. I've seen everything from using CAT to processing each line as necessary. I can't figure out what I should use and why. Attempts read -d '' versionNotes Results in garbled input if the user has to use the backspace key. Also there's no good way to terminate the input as ^D doesn't terminate and ^C just exits the process. read -d 'END' versionNotes Works... but still garbles the input if the backspace key is needed. while read versionNotes do echo " $versionNotes" >> "source/application.yml" done Doesn't properly end the input (because I'm too late to look up matching against an empty string).

  • Grails dependency inject domain classes

    - by Don
    Hi, The Grails manual shows this example of dependency injecting domain classes: class Book { def bookService def buyBook() { bookService.buyBook(this) } } However, I tried this out, and bookService is null. My guess is that the dependency injection happens when an object is loaded from the DB, so the following will always return null new Book().bookService Can someone confirm this?

  • Question regarding MySQL indices and their functionality

    - by user281434
    Hi Say I have an ordinary table in my db like so ---------------------------- | id | username | password | ---------------------------- | 24 | blah | blah | ---------------------------- A primary key is assigned to the id column. Now when I run a Mysql query like this: SELECT id FROM table WHERE username = 'blah' LIMIT 1 Does that primary key index even help? If I am telling it to match usernames, then shouldn't the username column be indexed instead? Thanks for your time

  • Hibernate Communications Link Failure in Restlet-Hibernate Based Java application powered by MySQL

    - by Vatsala
    Let me describe my question - I have a Java application - Hibernate as the DB interfacing layer over MySQL. I get the communications link failure error in my application. The occurence of this error is a very specific case. I get this error , When I leave mysql server unattended for more than approximately 6 hours (i.e. when there are no queries issued to MySQL for more than approximately 6 hours). I am pasting a top 'exception' level description below, and adding a pastebin link for a detailed stacktrace description. javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: Cannot open connection - Caused by: org.hibernate.exception.JDBCConnectionException: Cannot open connection - Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure - The last packet successfully received from the server was 1,274,868,181,212 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago. - Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure - The last packet successfully received from the server was 1,274,868,181,212 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago. - Caused by: java.net.ConnectException: Connection refused: connect the link to the pastebin for further investigation - http://pastebin.com/4KujAmgD What I understand from these exception statements is that MySQL is refusing to take in any connections after a period of idle/nil activity. I have been reading up a bit about this via google search, and came to know that one of the possible ways to overcome this is to set values for c3p0 properties as c3p0 comes bundled with Hibernate. Specifically, I read from here http://www.mchange.com/projects/c3p0/index.html that setting two properties idleConnectionTestPeriod and preferredTestQuery will solve this for me. But these values dont seem to have had an effect. Is this the correct approach to fixing this? If not, what is the right way to get over this? The following are related Communications Link Failure questions at stackoverflow.com, but I've not found a satisfactory answer in their answers. http://stackoverflow.com/questions/2121829/java-db-communications-link-failure http://stackoverflow.com/questions/298988/how-to-handle-communication-link-failure Note 1 - i dont get this error when I am using my application continuosly. Note 2 - I use JPA with Hibernate and hence my hibernate.dialect,etc hibernate properties reside within the persistence.xml in the META-INF folder (does that prevent the c3p0 properties from working?)

  • Looking for a central image database and tagging system for a group of users

    - by jstarek
    I'm doing IT support for a small volunteer organisation who needs to centrally store and organize around 2500 photos. Can anyone here recommend a database or similar system which matches the following criteria: Intuitive to use for users with little computer experience Multi-user support, ideally with integration in our existing LDAP user directory Should have a web-interface Not a hosted solution like Picasa (because we have a rather slow internet connection with very slow upload) Should allow tagging of images, sorting by various criteria and storing copyright information If there are native GNOME and/or Windows clients for the tool, that would be a great benefit. Many thanks in advance!

  • Dynamic sql vs stored procedures - pros and cons?

    - by skyeagle
    I have read many strong views (both for and against) SPs or DS. I am writing a query engine in C++ (mySQL backend for now, though I may decide to go with a C++ ORM). I cant decide whether to write a SP, or to dynamically creat the SQL and send the query to the db engine.# Any tips on how to decide?
