cursor

I'm developing a simple writing app for iPad. I'm trying to compute the pixel-position of the cursor in UITextView . I spend a few weeks to design this, but I still couldn't figure out to do it. In stackoverflow, Tony wrote one good algorithm to find the pixel-position of the cursor. Pixel-Position of Cursor in UITextView I implemented this with a little modification, and it almost works that it gives the correct pixel-position of the cursor. However, it only works with English alphabets. If there is Chinese or Japanese character at the end of line, UITextView performs character-wrapping,

I am using the MySQLdb module for Python (v1.2.3 precompiled binary for Windows Python 2.7) to read and write data to a MySQL database. Once a connection is open, I can use that connection to observe changes made to the database on that same connection, but do not see changes made using another connection, regardless of whether the other connection is made in Python or there is a change made using the MySQL command line client. In the case where I am making updates using Python, note that I am running the commit() command on the connection. Example of program that inserts new records into a

I updated my android SDK to the latest version, and now it says that startManagingCursor() is deprecated . I need help to update my code to use the new CursorLoader . private void fillData() { Cursor notesCursor = mDbHelper.fetchAllNotes(); startManagingCursor(notesCursor); NoteAdapter notes = new NoteAdapter(this, R.layout.notes_row, notesCursor); setListAdapter(notes); } So, startManagingCursor() is old, what would the new code look like, if it was translated? First, startManagingCursor() still works. It is not ideal, in that it performs database I/O on the main application thread. In

I have a memory problem that I can't figure out. I have one class that does all my database retrieving work. The error I have is the following: android.database.CursorWindowAllocationException: Cursor window allocation of 2048 kb failed. # Open Cursors=733 (# cursors opened by this proc=733) The memory allocation error occurs when I do this: mDatabaseInterface.getGraphForLevel(level); I know it's a leak because I call this method every 2.5 seconds roughly, and the 5 or 6 first calls go through easily. Now here are the methods in my DatabaseInterface class: public Graph getGraphForLevel(Level

From time to time, I'm executing raw queries using connection.cursor() instead of using ORM (since it is definitely not a silver bullet). I've noticed that in several places I don't call explicit cursor.close() after I'm done with database. So far, this hasn't result into any errors, or performance issues. I'm wondering what kind of problems could I possibly have without closing the cursor explicitly, what can go wrong? As far as I understand, connection and cursor in Django follow "Python Database API Specification v2.0" ( PEP-249 ). And, according to it, cursor would be automatically closed

I have 2 tables- student and studLoad both having 2 fields studID and studName . I want to load data from student table into stuLoad table. If the data already exists in the studLoad table, then it should be updated else it should be inserted. following is my code to do so: create or replace procedure studentLoad is v_id student.studID%type; v_name student.studName%type; v_sn studLoad.studName%type; cursor cur_load is select * from student; begin open cur_load; loop fetch cur_load into v_id,v_name; exit when cur_load%notfound; select studName into v_sn from studLoad where studID = v_id; if(v
