Database manipulation and management is an important component in Visual Basic programming. While creating databases are mostly handled by database software such Microsoft Access, MySql, Oracle, MS FoxPro and more, you can actually use a built-in database creation program in Visual Basic 6 called Visual Data Manager. Visual Data Manager can be used to create tables, add new data as well as edit data. Besides that, it can be used to modify table structure.

To learn how to create databases using Visual Data Manager , following the link below:

There are many types of data that we come across in our daily life. For example, we need to handle data such as names, addresses, money, date, stock quotes, statistics and more everyday. Similarly in Visual Basic, we have to deal with all sorts of of data, some can be mathematically calculated while some are in the form of text or other forms. VB divides data into different types so that it is easier to manage when we need to write the code involving those data.

Error handling is an essential procedure in Visual Basic 2012 programming because it helps make a program error-free. Error-free code not only enables the programs to run smoothly and efficiently, it can also prevent all sorts of problems from happening like program crashes or system hangs.

Errors often occur due to incorrect input from the user. For example, the user might make the mistake of attempting to enter text (string) to a box that is designed to handle only numeric values such as the weight of a person, the computer will not be able to perform arithmetic calculation for text therefore will create an error. These errors are known as synchronous errors.

Therefore a good programmer should be more alert to the parts of program that could trigger errors and should write errors handling code to help the user in managing the errors. Writing errors handling code is a good practice for Visual Basic 2012 programmers, so do not try to finish a program fast by omitting the errors handling code. However, there should not be too many errors handling code in the program as it create problems for the programmer to maintain and troubleshoot the program later.

We can create a password cracking program using Visual Basic. This Visual Basic 6 passwords cracker created by us can generate passwords and compare each of them with the actual password; and if the generated password found to be equal to the actual password, login will be successful. In this program, a timer is inserted into the form and it is used to do a repetitive job of generating the passwords.
