Get prepared for Microsoft Windows Server 2016 certification with a new seriesin production that will cover all the skills needed for the latest MCSE certification from Microsoft. Ready to go?. Security expert David Bigger is wrapping up a series on EC-Council’s ForensicInvestigator certification (CHFI). Forensic investigation is the process of detecting hacking attacks and properly extracting evidence to report the crime andconduct audits to prevent future attacks. Blog.This is a great climate for those looking to update their skills and join the relatively new and growing sector of IT security.
In a March 2018 article posted by Forbes, five of the top 15 most valuable IT certifications are security based. But which ones are right for you?.If you know anything about computer security, you’re probably familiar with CompTIA Security+, an internationally-recognized certificationfollowing in the footsteps of Security+ is CASP, or CompTIA Advanced Security Practitioner, CompTIA’s.For some programmers, investing the time and effort necessary to master C may not be the easiest sell. Even the most ardent supporters of C will acknowledge that when compared to other popular programming languages.
The American Red Cross (ARC) is one of the world's largest nonprofit social service organizations. ARC has a network of approximately 1,000 chapters in the United States and its territories; each is responsible for a specific geographic jurisdiction in which ARC provides an array of social services.
ARC is under pressure to demonstrate to the public how it is responsible and accountable for the resources it uses to deliver these services and the outcomes it achieves. Its decision makers are challenged to make accurate decisions to improve resource utilization and service-delivery processes. We designed and developed a system that uses data envelopment analysis to make resource-allocation recommendations that help ARC managers evaluate the performance of chapters at various levels.
We used Microsoft Excel for the model formulation and reporting. This paper describes its use, in conjunction with Premium Solver, Visual Basic for Applications, and Microsoft Access, to formulate 4,000 linear-programming models. The system performs the analysis and uses Excel to display the results visually.
We also discuss the benefits to ARC, lessons learned, and potential future improvements.

Microsoft launched VB.NET in 2002 as the successor to its original language. Although the '.NET' portion of the name was dropped in 2005, this article uses 'Visual Basic.NET' to refer to all Visual Basic languages released since 2002, in order to distinguish between them and the. Along with, it is one of the two main languages targeting the.NET framework.Microsoft's (IDE) for developing in Visual Basic.NET language is.

( April 2014)VB.NET uses to specify actions. The most common statement is an expression statement, consisting of an to be evaluated, on a single line. As part of that evaluation, may be and may be new values. To modify the normal sequential execution of statements, VB.NET provides several control-flow statements identified by reserved keywords. Is supported by several constructs including two conditional execution constructs ( If Then Else End If and Select Case. End Select ) and three iterative execution (loop) constructs ( Do Loop, For To, and For Each).
The For To statement has separate initialisation and testing sections, both of which must be present. (See examples below.) The For Each statement steps through each value in a list.In addition, in Visual Basic.NET:. There is no unified way of defining blocks of statements. Instead, certain keywords, such as 'If Then' or 'Sub' are interpreted as starters of sub-blocks of code and have matching termination keywords such as 'End If' or 'End Sub'. Statements are terminated either with a (':') or with the. Multiple line statements in Visual Basic.NET are enabled with ' ' at the end of each such line.
The need for the underscore continuation character was largely removed in version 10 and later versions. The ('=') is used in both assigning values to variables and in comparison. (parentheses) are used with, both to declare them and to get a value at a given index in one of them.
Visual Basic.NET uses round brackets to define the parameters of subroutines or functions. A (') or the keyword REM, placed at the beginning of a line or after any number of or characters at the beginning of a line, or after other code on a line, indicates that the (remainder of the) line is a.Simple example The following is a very simple VB.NET program, a version of the classic ' example created as a console application. Module Module1This is a module definition. Modules are a division of code, which can contain any kind of object, like constants or variables, functions or methods, or classes, but can't be instantiated as objects like classes and cannot inherit from other modules.
Modules serve as containers of code that can be referenced from other parts of a program.It is common practice for a module and the code file, which contains it, to have the same name; however, this is not required, as a single code file may contain more than one module and/or class definition. WriteLine ( 'Hello, world!'
)This line performs the actual task of writing the output. Console is a system object, representing a command-line interface (also known as 'console') and granting programmatic access to the operating system's. The program calls the Console method WriteLine, which causes the string passed to it to be displayed on the console.Instead of Console.WriteLine, one could use MsgBox, which prints the message in a dialog box instead of a command-line window. Complex example This piece of code outputs to the console. Main article:Whether Visual Basic.NET should be considered as just another version of Visual Basic or a completely different language is a topic of debate. There are new additions to support new features, such as and short-circuited expressions.
Also, two important data-type changes occurred with the move to VB.NET: compared to Visual Basic 6, the Integer has been doubled in length from 16 bits to 32 bits, and the Long has been doubled in length from 32 bits to 64 bits. This is true for all versions of VB.NET.
A 16-bit integer in all versions of VB.NET is now known as a Short. Similarly, the editor is very similar in style and function to the Visual Basic form editor.The things that have changed significantly are the semantics—from those of an object-based programming language running on a, engine based on to a fully language backed by the, which consists of a combination of the (a using and a engine) and a far larger.
The increased breadth of the latter is also a problem that VB developers have to deal with when coming to the language, although this is somewhat addressed by the My feature in Visual Studio 2005.The changes have altered many underlying assumptions about the 'right' thing to do with respect to performance and maintainability. Some functions and libraries no longer exist; others are available, but not as efficient as the 'native'.NET alternatives. Even if they compile, most converted Visual Basic 6 applications will require some level of to take full advantage of the new language. Documentation is available to cover changes in the syntax, debugging applications, deployment and terminology. Comparative examples The following simple examples compare VB and VB.NET syntax. They assume that the developer has created a form, placed a button on it and has associated the subroutines demonstrated in each example with the click event handler of the mentioned button. Each example creates a 'Hello, World' message box after the button on the form is clicked.Visual Basic 6.
Private Sub Button1Click ( sender As object, e As EventArgs ) Handles Button1. Click MsgBox ( 'Hello, World' ) End Sub.
Both Visual Basic 6 and Visual Basic.NET automatically generate the Sub and End Sub statements when the corresponding button is double-clicked in design view. Visual Basic.NET will also generate the necessary Class and End Class statements. The developer need only add the statement to display the 'Hello, World' message box.
All procedure calls must be made with parentheses in VB.NET, whereas in Visual Basic 6 there were different conventions for functions (parentheses required) and subs (no parentheses allowed, unless called using the keyword Call). The names Command1 and Button1 are not obligatory. However, these are default names for a command button in Visual Basic 6 and VB.NET respectively. In VB.NET, the Handles keyword is used to make the sub Button1Click a handler for the Click event of the object Button1. In Visual Basic 6, event handler subs must have a specific name consisting of the object's name ('Command1'), an underscore ('), and the event's name ('Click', hence 'Command1Click').
There is a function called MessageBox.Show in the Microsoft.VisualBasic namespace which can be used (instead of MsgBox) similarly to the corresponding function in Visual Basic 6. There is a controversy about which function to use as a best practice (not only restricted to showing message boxes but also regarding other features of the Microsoft.VisualBasic namespace). Some programmers prefer to do things 'the.NET way', since the Framework classes have more features and are less language-specific. Others argue that using language-specific features makes code more readable (for example, using int (C#) or Integer (VB.NET) instead of System.Int32). In Visual Basic 2008, the inclusion of ByVal sender as Object, ByVal e as EventArgs has become optional.The following example demonstrates a difference between Visual Basic 6 and VB.NET. Both examples close the.Visual Basic 6. Main article:C# and Visual Basic.NET are Microsoft's first languages made to program on the.NET Framework (later adding and more and others have also added languages).
Though C# and VB.NET are syntactically different, that is where the differences mostly end. Microsoft developed both of these languages to be part of the same.NET Framework development platform. They are both developed, managed, and supported by the same language development team at Microsoft.
They compile to the same intermediate language (IL), which runs against the same.NET Framework runtime libraries. Although there are some differences in the programming constructs, their differences are primarily syntactic and, assuming one avoids the Visual Basic 'Compatibility' libraries provided by Microsoft to aid conversion from Visual Basic 6, almost every command in VB has an equivalent command in C# and vice versa. Lastly, both languages reference the same Base Classes of the.NET Framework to extend their functionality. As a result, with few exceptions, a program written in either language can be run through a simple syntax converter to translate to the other.
There are many open source and commercially available products for this task.Examples Hello World! Windows Form Application Requires a button called Button1. Module Module1 Private Voice = CreateObject ( 'Sapi.Spvoice' ) Private Text As String Sub Main Console. Write ( 'Enter the text to speak: ' ) ' Say 'Enter the text to speak: ' Text = Console. ReadLine ' The user must enter the text to speak.
Speak ( Text ) ' Speak the text the user has entered. End Sub End Module Version history Succeeding version 6.0, the first version of Visual Basic.NET debuted in 2002.
As of 2017, eight versions of Visual Basic.NET are released.2002 (VB 7.0) The first version, Visual Basic.NET, relies on. The most important feature is, which contrasts with the classic Visual Basic.2003 (VB 7.1) Visual Basic.NET 2003 was released with. New features included support for the and a better VB upgrade.
