cursor

一：SQLite 1.1.Sqlite数据库简介 　　SQLite是一个嵌入式的数据库，他的数据库是个文件。 　　SQLite本身是c语音写的，所以经常被集成到各种应用程序。 　　python就内置了SQLite，所以python使用SQLite不需要安装任何东西，直接进行使用。 　　连接到数据库后需要打开游标，称之为Cursor，通过Cursor执行sql预计和执行后的结果。 1.2使用SQLite数据库 python中内置的与mysql交互的方法如下： #导入SQLit3 import sqlite3 #连接sqlite3数据库，数据库文件是test.db,如果文件不存在会自动在当前目录中创建 conn = sqlite3.connect('test.db') #创建一个Cursor cursor = conn.cursor() #创建一个user表 cursor.execute('create table user (id varchar(20) primary key, name varchar(20) )') #插入一条记录 cursor.execute(inser into user(id , name) values('1', 'yaohong' )) #获取插入的条数 print cursor.rowcount #关闭cursor cursor.close()

I have a some text boxes in my form. I don't know their id values. I want change the cursor position from the existing one to the next field by pressing Enter. Pay attention that the cursor may be in different positions at the first time. What is your suggestion? you didn't provide your markup so I can't make assumption about your structure (e.g. using .next() if they are sibling elements). So, supposing you have input text, try this example (for jQuery 1.7+) $(document).ready(function() { var inputs = $('input[type="text"]'); var len = inputs.length; inputs.on('keyup', function(evt) { if (evt

I am using Starling to make a really, really, really easy game - I am just trying to add a stationary sprite to the stage...and make it so that when the mouse touches the sprite...the game "stops" and a score is sent. I haven't tried implementing hitTest yet for the collision, but I have run into a sort of conflict problem where, when I comment out the line(s) that is supposed to change the cursor image (see Startup.as - stage.addEventListener(TouchEvent.TOUCH, touchHandler); and createCustomeCursor ), the instance of AvatarEnemy (see enemy in Game.as) does what it should, and is placed in the

I write a program that can show data that stored in database in listview by cursor.but in runtime it gives me force close.I read logcat but i don t understand what is this error.I give my code and logcat.please help me current_cart code: public class current_cart extends ListActivity { private ListView mainListView = null; CustomSqlCursorAdapter adapter = null; private SqlHelper dbHelper = null; private Cursor currentCursor = null; private ListView listView = null; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate

CREATE PROCEDURE p_processDataFor @accountId BEGIN for each item in (select * from Accounts where accountId = @accountId and isProcessed = 0) BEGIN CASE current row WHEN has x Condition THEN exec p_x <Pass all data of current row> WHEN has y Condition THEN exec p_y <Pass all data of current row> WHEN has z Condition THEN exec p_z <Pass all data of current row> END END END Okay, this example only does the insert for condition X, but hopefully shows you the way you could proceed: create table T1 ( ID int IDENTITY(1,1) not null, Val1 varchar(10) not null, constraint PK_T1 PRIMARY KEY (ID) ) go

First of all, please put aside notions of "Your application shouldn't do this". This is exactly what the people purchasing this software will be expecting. How can I, system-wide, increase the size of the mouse cursor? I'd have to increase all mouse cursors too, so I don't think SetCursor would do the trick, at least not in any nice, clean way. And I can't use the Form's Cursor Size as detailed here , as this would only affect the cursor when it's active on the form. I see that there are "Extra Large" Mouse Cursors available in Windows' Ease-of-Access Centre, so there must be a way... Any
