There are lots if times when the system needs to be restarted, for example, after changing the autoexec.bat path. Here is code you can use, in the place of writing

Creating a VB routine that copies a whole directory tree can be a time-consuming job, but fortunately you don’t have to do it. In fact, you can quickly create an

If you want to stop a user from accessing your website, you can do it by using some relatively simple code. First, you must know the IP address of the

To make this script work, browsers should be javascript enabled.1) To Make TextBox Readonly:

This feature will be required if you want to store exceptions in a database: import java.io.*;public class Test{ public static void main(String args[]) { String trace = exceptionToString(new Exception(A new

The garbage collector works automatically, whether you request it to or not. However, it is possible to make a garbage collector request, by invoking the System.gc() method. When garbage collector

When working with pages, the database is not always available. Sometimes, you need to access a test recordset. Here are is an example of how to create a function that

While definitely not required, overriding the toString() method in your classes will make their use much easier. Although java.land.Object provides basic implementation for this method, it is far from being

The library defines the following open modes and file attributes: ios::app // appendios::ate // open and seek to file’s endios::binary // binary mode I/O (as opposed to text mode)ios::in //

Certain files need to be emptied every time an application opens them before it writes new data to them, for example, a per-session log file. One way to achieve this

The keywords struct and class are almost interchangeable in C++. You can declare a struct that has member functions, constructors, destructor, base classes and so on as if it were

Some programmers consistently define an empty constructor and destructor in their classes, as in: class A{//..public: A() {} ~A() {}}; This is totally useless. C++ guarantees that when a class

Following yesterday’s tip, here’s another deprecated habit that programmers should avoid. Consider the following class hierarchy: class base{public: base();};class derived: public base{public: derived() : base() {/*some code*/} // superfluous}; The

Listboxes provide suitable functionality to act as a quick queue. Create a listbox named ListMyQueue. Use this code to add to your Queue: Public Sub Enqueue(StringToAdd As String)If Len(String_to_Add) >

User-defined types are useful when you need to store structured data that has no specific behavior. If you have associated behavior, you should encapsulate the data in its own class.

Sometimes you might want an MDI form without any captions or buttons, such as in a game or acting as a background parent object. You can create a captionless MDI

Enumerated constants are great, but they have a quirk that

When you need to determine the last occurrence of a character within a larger string, you typically use a Mid$ or Instr in a loop. VB6

Creating a new project in VB6 (and earlier versions) has always been a pain when you have a large library of modules to add in. You can do it a
