We will prepare and launch our Visual Basic 2013 tutorial as soon as possible for the benefits of our readers. Right now you can use the sample codes in Visual Basic 2012 tutorial to test them out in Visual Basic 2013.
Handling Keyboard Events in Visual Basic 6
In Visual Basic, we can write codes for handling events triggered by input from the keyboard. When the user presses a key on the keyboard, it will trigger an event or a series of events. These events are called the keyboard events. In Visual Basic, the three basic event procedure to handle the keyboard events are KeyPress, Keydown and KeyUp
The keyboard event occurs when the user presses any key that corresponds to a certain alphanumeric value or an action such as Enter, spacing, backspace and more. Each of those value or action is represented by a set of code known as the ASCII . ASCII stands for American Standard Code for Information Interchange. ASCII stands for American Standard Code for Information Interchange. Computers can only understand numbers, so an ASCII code is the numerical representation of a character such as ‘a’ or ‘@’ or an action of some sort. ASCII was developed a long time ago and now the non-printing characters are rarely used for their original purpose.In order to write code for the Keyboard events , we need to know the ASCII and the corresponding values
Creating Passwords Cracking Program using Visual Basic 6
This Visual Basic 6 passwords cracking program can generate possible 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, three timers are inserted into the form The passwords generating code is entered under each of the Timer () event by double-clicking the relevant timer . The interval of the timers can be set in their properties window where a value of 1 is equivalent to 1 millisecond, and a value of 1000 is 1 second; the smaller the value, the shorter the interval. The Timer’s Enabled property is set to false so that the program will only start generating the passwords after the user clicks on the command button.
Using Timer in Visual Basic 2012
In Visual Basic 2012, the timer control is used to manipulate events that are time related. For example, you need timer to create a clock, a stop watch, a dice, animation and more.
In order to create a clock, you need to use the Timer control that comes with Visual Basic 2012. The Timer control is a control object that is only used by the developer, it is invisible during runtime and it does not allow the user to interact with it.
To create the clock, start a new project in Visual Basic 2012 Express and select a new Windows Application. You can give the project any name you wish, but we will name it MyClock. Change the caption of the Form1 to MyClock in the properties window. Now add the Timer control to the form by dragging it from the ToolBox. Next, insert a label control into the form………..
