Facebook users of high sensory and social work affiliate network in Vietnam is blocked again, this time by various companies internet service provider (ISP).
30/12 noon next Thursday, on Facebook overwhelming message in English about the ISP, such as Viettel, FPT, and the first time both VNPT, has blocked access to users, and shared experiences " exceed the equivalent. "
However, some known "trick" as repaired or changed DNS proxy parameters also have no effect.
Late last year, Facebook users in Vietnam also have problems in retrieving update, causing speculation that the common use of this website may be prohibited in Vietnam like China.
Not only in Vietnam, many countries and territories also find ways to manage your blog, or make rules to regulate the behavior of bloggers (bloggers) to stem the tide take advantage of communication tools false information, harm the legitimate rights and interests of organizations and individuals. Blogging for social management Shared with the press in the second mission in Vietnam May 3-2009, Yahoo vice president Ken Mandel said that management is normal blog.Mr. Mandel explains, the Internet is a nascent industry and rapid growth rate should not only Vietnam but the government most of the countries in the world still have to learn and make many other management methods each other. BBC news dated 10-10-2010 cited research project results online behavior of users worldwide by TNS Global Market Research (UK) shows that, for every 4 people 5 people are Chinese and was writing blog.That means the number of bloggers in China is a world leader. China is also the country launched various measures to manage the blog is close today.Many blog service providers have signed agreements with the Social Network in China's Ministry of Information, requires bloggers to register an account with their real names.
Google supports data migration between platforms blog
Google has introduced an open source project is very useful to be expected for a long time user - Google Blog Converters project.This is a tool that can convert bloggers blog from this platform to other platforms easily.
Visual Basic 6 gives us the choice of technique when programming with database, or use DAO as in the previous two articles, or are using ADO (ActiveX Data Objects) .
The main difference between ADO and the ADO DAO allows us to work with any type of data sources (data sources), not necessarily the Access database or ODBC.Data sources can be a list of email addresses, or a text string, where each row is a record consisting of fields separated by commas ( comma separated values ).
If the DAO is used directly in the name of the Database MSAccess ADO us connected (connect) a database through a Connection by specifying a Connection String .In the Connection String Database Provider (such as Jet, ISAM, Oracle, SQLServer, etc. ..), Database name, username / password logon to a database. etc.Then we can retrieve (extract) the recordsets and update the records using the SQL command used on the tables or stored procedures inside the database.
In this article we will learn basic programming with MS Access database through DAO techniques without the use of the Control Data as in the previous post.I will need some DAO Objects in the library, so if you open a new VB6 project, use the Command Menu Project | References ... to select the Microsoft DAO Object Library 3:51 by clicking the checkbox to the left like in the picture below here.(One way to remember the name of this object is to remember the sentence "He's DAO 35 goats" ).
From VB5, Visual Basic for a programmer to control access to databases, it's just a simple name is Data.As we know, there is a database when you buy bundled Microsoft VB6 - that is Jet Database Engine .Jet Database Engine is the "engine room" of the MS Access Database Management System.
Until VB5, Microsoft gives us three main techniques:
DAO (Data Access Objects) : DAO is esoteric techniques of Microsoft, just to use the Jet Database Engine.It is easy to use, performance and convenience, but are limited within MS Access.Nevertheless, it is so prevalent because there are practical benefits.
ODBC (Open Database Connectivity) : ODBC is designed to let users connect with all sorts of databases that use only a single method.This put the burden for the programmer, to just learn a single programming techniques that can work with any database of any kind.Especially if you later need to change the type of database, such as upgrading from Access to SQLServer instance, the alteration of very little coding.When using ODBC with DAO, you can connect to Access Database with other databases.There is a disadvantage of ODBC is that it is confusing.
RDO (Remote Data Object) : One of the main reasons for RDO is designed to solve the difficult problem of ODBC.How to program with simple DAO RDO, but actually it should allow users to use ODBC connections to multiple databases.However, the RDO is not very prevalent.
