VS.NET has a nice feature that allows you to visually navigate through the content of hierarchical files, and quickly jump to a particular section. Hierarchical files are all those files

When you create a new project, VS.NET automatically creates a folder with the project’s name under the selected directory. If you name your project MyTestProject, and select an existing folder

Visual Studio .NET has a number of useful features that are often underused by developers, because they are hidden under several menus and not easily accessible. Here is a list

Sometimes it’s convenient to have your program be runnable both as an applet and as an application. One simple way of accomplishing this derives from the fact that any class

The program is used to display the current and parent directory. ‘.’represents the current directory and ‘..’ represents the parent directory import java.io.File; public class CurrentDir { public static void

It is said that C++ provides data hiding, but the following code shows that this is not always true. You can break the C++s data-hiding facility using the memory function:

There is no TSQL function for extracting maximum values across columns. However, you can use MAX() and MIN() functions to obtain the maximum or minimum value in any particular row.

The following piece of code is a sample example that can print a HTML page without showing the print-popup dialog box. NOTE: It is restricted with IE 5.5 SP2 onwards.

Assertions are excellent at catching bugs during development. However, some checks need to be performed at runtime for production code as well. A good way to wrap the two is

The following code disables right mouse click.

Where possible, use interfaces (as opposed to interface-implementation classes) to increase your source code’s flexibility. If you later need to change an interface-implementation class (to improve performance, for example), it’s

File hierarchies are becoming more complex and file paths longer as the capacity of hard drives increases. There are still many occasions, however, when you can’t browse to identify a
