In this video series, you will learn java language basics. This playlist talks about language fundamentals and concepts. Here we will not dig into JAVA SDK and API. We will learn it in a separate video series. We would suggest learning java language before going to the JAVA SDK. This series is having 6 hours of learning.
Master Pages help in providing the consistently laid-out pages. When we switch between other pages, we can note the steady look and feel throughout the websites. Microsoft provides Master Page support from ASP.Net 2.0 onward. The Master Page is used to making the outer skeleton structure of the websites and we can see this outer skeleton as web page header, footer and sidebars with navigational elements. In this example, we will explore how to create a Master page along with other web pages.
In this article, we will see how we play an AVI video file in MFC Application. To play the AVI file, we will use the Media Control Interface (MCI) function and its API function MCIWndCreate. The Animate control that ships with MFC can play the AVI files, but you will not get any sound when the video is playing. OK. Let us start with this simple and quick example that plays the video file comp.avi. The AVI file that I am packing with this example has no sound information, so replace that with any video file, which has sound information in it. Note, we call the MCIWndCreate API from the MCI interface embedded into the MFC dialog.
The Register and Leave button share same Performance Counter called Register Click and Update button uses a one more Counter called Update Click. This example form increments the Counters Register Click and Update Click when user clicks the relevant buttons Register and Update. The Leave button will reduce the Register Click performance count by one. This example looks hollow. But it is just for a tryout purpose.
In the real case, these kinds of click counts are useful to measure Performance of the Operator. Say, for example, a click count on the print button measures how many billing is done in an hour by an operator on the billing counter of a retail shop. The perfmon can plot the graph over time, showing how many billing a billing counter staff clears. You can think of a better example than this one once you know how this Example works.
An ‘SQL Trigger’ is a compiled unit of SQL Server procedure, which can run automatically when an event occurs on the database objects. For example, you can write a piece of SQL Script (the trigger), which can be called whenever an insert (the event) takes place on a specific table. There are various types of triggers possible in SQL Server. The two crucial types are:
DDL Triggers: These triggers act on ‘Data Definition Language’; say, for example, a trigger procedure runs whenever a table is created. We can say DDL trigger as an ‘Database level trigger’ hence it acts on the DB. SQL Server invokes the Trigger procedure whenever the manipulation like Create, Alter and Drop takes place on its DB objects.
DML Triggers: These triggers act on ‘Data Manipulation Language’. In DB world, the tables maintain the Data. So, we can do manipulating data through the tables by making use of Insert, Update and Delete statements on the table. We can call DML trigger as an ‘Table Level Trigger’ since it operates at table level. Simply,
