    - by devlearn

A doc or an example of a (not too complex) web app using storage backends other than a relational database would be greatly appreciated. It's not clear on what should be implemented in the model classes in order to make the rails app work without the ActiveRecord layer. Thanks,

    - 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(); }

    I have a recursive function reading a "table of contents" of documents from a database.

  • how to code client-side call to webservice that calls automatically every few seconds

    - by Bob Jones
    I have a webservice that I want to call from the browser every few seconds to see if there are any notification messages in the database that should be displayed on the screen. We have the JSON code working to display the messages in a JavaScript function after an Async Postback, but this only executes after a page turn. I want it to execute every 10-15 seconds as well. A code sample would be very helpful.

  • HTML tags in mysql text field

    - by paracaudex
    I'm creating a database with what I anticipate will be a long (perhaps several paragraphs for some tuples) attribute. I'm assigning it text instead of varchar. I have two questions: Should I give a maximum value for the text field? Is this necessary? Is it useful? Since the contents of this field will be displayed on a website in HTML, do I need to include paragraph tags for paragraph formatting when I enter records into mysql?

  • Using jquery to prevent resubmitting form

    - by Tony
    I use jquery's .submit() to intercept user's submit event, however I found a problem. When the user single click the submit button, the form is submitted normally, but if a user deliberately fast click it multiple times, it will submit multiple times, which will cause duplicated data in the database. What's the solution for this kind of problem ?

    - by crisgomez
    I have a problem regarding json web service security.

What are the approach to secure the calling of the exposed web service?

  • Sequential GUID in Linq-to-Sql?

    - by JacobE
    I just read a blog post about NHibernate's ability to create a GUID from the system time (Guid.Comb), thus avoiding a good amount of database fragmentation. You could call it the client-side equivalent to the SQL Server Sequential ID. Is there a way I could use a similar strategy in my Linq-to-Sql project (by generating the Guid in code)?

  • How to modify preorder tree traversal algorithm to handle nodes with multiple parents?

    - by poldo
    I've been searching for a while now and can't seem to find an alternative solution. I need the tree traversal algorithm in such a way that a node can have more than 1 parent, if it's possible (found a great article here: Storing Hierarchical Data in a Database). Are there any algorithms so that, starting from a root node, we can determine the sequence and dependencies of nodes (currently reading topological sorting)?

  • Creating views with PHP for couchDB

    - by Industrial
    Hi! I have started to try out noSQL databases now and are currently testing out couchDB. Seems like a good solution, but I really get some headache when I follow available examples on how to create views (queries) to select documents from a database and sort them. Everything I can find is regarding Javascript and it would be great to take part of some examples for PHP since that is the language we will use. So, how do I create views using PHP for couchDB?

I know R is great with Time Series, but I am not sure where to start. I have two questions: 1- I have the raw invoice data but have aggregated it for reporting purposes. Would it be easier if I didn't aggregate the data? 2- Regardless of aggregation or not, what functions will I need to loop over each product and generate the lags as I need them? In short, I want to loop over a set of records, calculate lags for a product (if possible), append the lags (as they apply) to the current record for each product, and write the results back to a table in my database for my reporting software to use. Any help you can provide will be greatly appreciated! Many thanks in advance, Brock
