4 Dynamic-link library Microsoft Visual BasicWhen creating DLLs in VB, the IDE will only allow you to create ActiveX DLLs, however methods have been created to allow the user to explicitly tell the linker to include a .DEF file which defines the ordinal position and name of each exported function. This allows the user to create a standard Windows DLL using Visual Basic (Version 6 or lower) which can be referenced through a "Declare" statement. https://store.theartofservice.com/the-visual-basic-toolkit.html

10 Gambas - Differences from Visual BasicGambas is intended to provide a similar experience as developing in Microsoft Visual Basic, but it is not a free software clone of the popular proprietary program. The author of Gambas makes it clear that there are similarities to Visual Basic, such as syntax for BASIC programs and the integrated development environment; Gambas was written from the start to be a development environment of its own and seeks to improve on the formula. https://store.theartofservice.com/the-visual-basic-toolkit.html

11 Gambas - Differences from Visual BasicIts object model and each class being represented in a file, the archiver to package the program is inspired by the Java programming language. Gambas is intended to be an alternative for former Visual Basic developers who have decided to migrate to Linux. There are also other important distinctions between the Gambas and Visual Basic. One notable example is that in Gambas array indexes always start with 0, whereas Visual Basic indexes can start with 0 or 1. https://store.theartofservice.com/the-visual-basic-toolkit.html

13 Subroutine - Visual Basic 6 examplesBy value [ByVal] – a way of passing the value of an argument to a procedure instead of passing the address. This allows the procedure to access a copy of the variable. As a result, the variable's actual value can't be changed by the procedure to which it is passed. https://store.theartofservice.com/the-visual-basic-toolkit.html

14 Subroutine - Visual Basic 6 examplesBy reference [ByRef] – a way of passing the address of an argument to a procedure instead of passing the value. This allows the procedure to access the actual variable. As a result, the variable's actual value can be changed by the procedure to which it is passed. Unless otherwise specified, arguments are passed by reference. https://store.theartofservice.com/the-visual-basic-toolkit.html

30 Visual Basic A dialect of Visual Basic, Visual Basic for Applications (VBA), is used as a macro or scripting language within several Microsoft applications, including Microsoft Office. https://store.theartofservice.com/the-visual-basic-toolkit.html

31 Visual Basic - Language featuresLike the BASIC programming language, Visual Basic was designed to accommodate beginner programmers https://store.theartofservice.com/the-visual-basic-toolkit.html

32 Visual Basic - Language featuresThough VB programs can be compiled into native code executables from version 5 on, they still require the presence of around 1 MB of runtime libraries. Runtime libraries are included by default in Windows 2000 and later. Earlier versions of Windows (95/98/NT), require that the runtime libraries be distributed with the executable. https://store.theartofservice.com/the-visual-basic-toolkit.html

33 Visual Basic - Language featuresForms are created using drag-and-drop techniques https://store.theartofservice.com/the-visual-basic-toolkit.html

34 Visual Basic - Language featuresVisual Basic can create executables (EXE files), ActiveX controls, or DLL files, but is primarily used to develop Windows applications and to interface database systems. Dialog boxes with less functionality can be used to provide pop-up capabilities. Controls provide the basic functionality of the application, while programmers can insert additional logic within the appropriate event handlers. https://store.theartofservice.com/the-visual-basic-toolkit.html

35 Visual Basic - Language featuresFor example, a drop-down combination box automatically displays a list. When the user selects an element, an event handler is called that executes code that the programmer created to perform the action for that list item. https://store.theartofservice.com/the-visual-basic-toolkit.html

36 Visual Basic - Language featuresAlternatively, a Visual Basic component can have no user interface, and instead provide ActiveX objects to other programs via Component Object Model (COM). This allows for server-side processing or an add-in module. https://store.theartofservice.com/the-visual-basic-toolkit.html

37 Visual Basic - Language featuresUnlike many other programming languages, Visual Basic is generally not case sensitive—though it transforms keywords into a standard case configuration and forces the case of variable names to conform to the case of the entry in the symbol table https://store.theartofservice.com/the-visual-basic-toolkit.html

38 Visual Basic - Language featuresThe Visual Basic compiler is shared with other Visual Studio languages (C, C++), but restrictions in the IDE do not allow creation of some targets (Windows model DLLs) and threading models. https://store.theartofservice.com/the-visual-basic-toolkit.html

39 Visual Basic - CharacteristicsThe following Visual Basic traits differ from C-derived languages: https://store.theartofservice.com/the-visual-basic-toolkit.html

40 Visual Basic - CharacteristicsStatements tend to terminate with keywords, such as "End If", instead of using "{}"s to group statements. https://store.theartofservice.com/the-visual-basic-toolkit.html

41 Visual Basic - CharacteristicsMultiple variable assignment is not possible. A = B = C does not imply that the values of A, B and C are equal. The boolean result of "Is B = C?" is stored in A. The result stored in A would therefore be either false or true. https://store.theartofservice.com/the-visual-basic-toolkit.html

42 Visual Basic - CharacteristicsBoolean constant True has numeric value −1 https://store.theartofservice.com/the-visual-basic-toolkit.html

43 Visual Basic - CharacteristicsLogical and bitwise operators are unified. This is unlike some C-derived languages (such as Perl), which have separate logical and bitwise operators. This again is a traditional feature of BASIC. https://store.theartofservice.com/the-visual-basic-toolkit.html

44 Visual Basic - CharacteristicsThis uncommon trait does exist in Visual Basic .NET but not in VBScript. https://store.theartofservice.com/the-visual-basic-toolkit.html

48 Visual Basic - CharacteristicsThere are 12 Deftype statements in total offered by Visual Basic 6.0 https://store.theartofservice.com/the-visual-basic-toolkit.html

49 Visual Basic - History VB 1.0 was introduced in The drag and drop design for creating the user interface is derived from a prototype form generator developed by Alan Cooper and his company called Tripod. Microsoft contracted with Cooper and his associates to develop Tripod into a programmable form system for Windows 3.0, under the code name Ruby (no relation to the Ruby programming language). https://store.theartofservice.com/the-visual-basic-toolkit.html

50 Visual Basic - History Tripod did not include a programming language at all. Microsoft decided to combine Ruby with the Basic language to create Visual Basic. https://store.theartofservice.com/the-visual-basic-toolkit.html

51 Visual Basic - History The Ruby interface generator provided the "visual" part of Visual Basic and this was combined with the "EB" Embedded BASIC engine designed for Microsoft's abandoned "Omega" database system. Ruby also provided the ability to load dynamic link libraries containing additional controls (then called "gizmos"), which later became the VBX interface. https://store.theartofservice.com/the-visual-basic-toolkit.html

72 Visual Basic - Performance and other issuesEarlier versions of Visual Basic (prior to version 5) compiled the code to P-Code only. The P-Code is interpreted by the language runtime. The benefits of P-Code include portability and smaller binary file sizes, but it usually slows down the execution, since having a runtime adds an additional layer of interpretation. However, small amounts of code and algorithms can be constructed to run faster than compiled native code. https://store.theartofservice.com/the-visual-basic-toolkit.html

123 Visual Basic .NET - Comparative examples* Both Visual Basic 6 and Visual Basic .NET automatically generate the Sub and End Sub statements when the corresponding button is 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. https://store.theartofservice.com/the-visual-basic-toolkit.html

124 Visual Basic .NET - Comparative examples* All procedure calls must be made with parentheses in VB.NET, whereas in VB6 there were different conventions for functions (parentheses required) and subs (no parentheses allowed, unless called using the keyword Call). https://store.theartofservice.com/the-visual-basic-toolkit.html

125 Visual Basic .NET - Comparative examples* The names Command1 and Button1 are not obligatory. However, these are default names for a command button in VB6 and VB.NET respectively. https://store.theartofservice.com/the-visual-basic-toolkit.html

126 Visual Basic .NET - Comparative examples* In VB.NET, the Handles keyword is used to make the sub Button1_Click a handler for the Click event of the object Button1. In VB6, event handler subs must have a specific name consisting of the object's name (Command1), an underscore (_), and the event's name (Click, hence Command1_Click). https://store.theartofservice.com/the-visual-basic-toolkit.html

133 Visual Basic .NET - CriticismWhen first introduced, many long-time Visual Basic users complained about Visual Basic .NET because initial versions dropped a large number of language constructs and user interface features that were part of VB6 (which is no longer sold by Microsoft), and changed the semantics of those that remained; for example, in VB.NET parameters are (by default) passed by value, not by reference https://store.theartofservice.com/the-visual-basic-toolkit.html

134 Visual Basic .NET - CriticismMany of the changes were necessary because they needed to reflect differences between Windows Foundation Classes and equivalent classes in the .NET framework (e.g., for user-interface controls): in addition, certain changed features, such as restricting the scope of local variables to the block where they were declared, and passing parameters by value (which is the only means permitted in Java) make code less error-prone https://store.theartofservice.com/the-visual-basic-toolkit.html

135 Visual Basic .NET - CriticismHowever, many of these semantic changes were not backward-compatible with much existing code, and existing code required rewriting and testing, a significant expense when the body of code was non-trivial in size https://store.theartofservice.com/the-visual-basic-toolkit.html

136 Visual Basic .NET - CriticismMicrosoft's IDE, Visual Studio, did support some degree of automatic translation to VB.NET when VB6 code was pasted into Visual Studio https://store.theartofservice.com/the-visual-basic-toolkit.html

137 Visual Basic .NET - CriticismIt is simpler to decompiler|decompile languages that target Common Intermediate Language (CIL), including VB.NET, compared to languages that compile to machine code. Tools such as .NET Reflector can provide a close approximation to the original code due to the large amount of metadata provided in CIL. This is also true of early versions of Visual Basic (prior to VB5), which could not compile to native code. https://store.theartofservice.com/the-visual-basic-toolkit.html

138 Visual Basic .NET - CriticismVisual Basic 6.0 programs that are mainly algorithmic in nature can be migrated with few difficulties, but certain types of code are more troublesome, namely : https://store.theartofservice.com/the-visual-basic-toolkit.html

139 Visual Basic .NET - Criticism* Database support: .NET's framework for database access, ADO.NET, emphasizes disconnected operations, which use database-server resources as economically as possible by releasing them when not in use. This results in more scalable code than if the older Data Access Objects or ActiveX Data Objects were used, but the code is also more complex. https://store.theartofservice.com/the-visual-basic-toolkit.html

140 Visual Basic .NET - Criticism* Graphics: .NET has new (and more powerful) libraries for graphics. https://store.theartofservice.com/the-visual-basic-toolkit.html

141 Visual Basic .NET - Criticism* Unmanaged operations: .NET, like Java, emphasizes security, so unmanaged code is used only as a last resort. https://store.theartofservice.com/the-visual-basic-toolkit.html

142 Visual Basic .NET - CriticismOther syntactical differences relate to changes made to bring VB.Net into alignment with other .Net languages, such as zero-based arrays (all .Net arrays are only 0 to n-1 subscript, whereas classic VB arrays could be defined as either zero-based or one-based (1 to n subscript)), and structured exception handling (classic VB used a proprietary ON ERROR mechanism); such changes can be difficult or impossible to convert automatically, and converters typically flag such problem areas for manual conversion. https://store.theartofservice.com/the-visual-basic-toolkit.html

143 Visual Basic .NET - CriticismIn addition, the required Run time system|runtime libraries for VB6 programs are provided with Windows 98 SE and above, while VB.NET programs require the installation of the significantly larger .NET Framework https://store.theartofservice.com/the-visual-basic-toolkit.html

VBX has also been supported in some versions of Borland Delphi. https://store.theartofservice.com/the-visual-basic-toolkit.html

175 Visual Basic ExtensionThe VBX specification was created so that developers could extend Visual Basic. Since at the time Visual Basic was an interpreted language with limited speed, VBXs, which were most often written in C or C++, provided the ability to create very powerful and efficient user interface sub-components which could be assembled into applications using Visual Basic as the glue. https://store.theartofservice.com/the-visual-basic-toolkit.html

176 Visual Basic ExtensionVisual Basic 4.0 added support for the newer Object_Linking_and_Embedding#OLE_custom_controls|OLE Controls or 'OCX's (which became 'ActiveX' controls), implicitly deprecating VBX controls.

229 Comparison of Visual Basic and Visual Basic .NET - On the surfaceA programmer who has only worked with Visual Basic may have a bit of a learning curve to migrate to Visual Basic .NET|Visual Basic.NET. A programmer who is versed in another language or who has had exposure to the .NET runtime should be able to cope. It would be better to think of Visual Basic .NET|Visual Basic.NET as an interface to .NET rather than a continuation of Visual Basic https://store.theartofservice.com/the-visual-basic-toolkit.html

241 Comparison of Visual Basic and Visual Basic .NET - Zero-based arraysWhile the .NET Common Language Runtime can support arrays with any base value, Visual Basic .NET|Visual Basic.NET and C Sharp (programming language)|C# provide only zero-based arrays and lists, and the .NET Common Language Infrastructure|Common Language Specification requires zero-based arrays for interoperability between .NET languages. https://store.theartofservice.com/the-visual-basic-toolkit.html

242 Comparison of Visual Basic and Visual Basic .NET - Jagged ArraysVisual Basic .NET|Visual Basic.NET introduced the concept of a Jagged Array, whereby the rows can have unequal length as opposed to the uniform length of arrays imposed on Visual Basic programmers. https://store.theartofservice.com/the-visual-basic-toolkit.html

243 Comparison of Visual Basic and Visual BasicComparison of Visual Basic and Visual Basic .NET - Variant data type is gone In languages compiling down to .NET platform, types are strict. Whilst the runtime allows for anonymous object which don't have a pre-defined, named type, the type of a variable may not change over the course of its life-time, hence the need to drop the Variant data-type. The loss of the type is, however, a good thing: the Variant data type imposed a performance overhead. https://store.theartofservice.com/the-visual-basic-toolkit.html

244 Comparison of Visual Basic and Visual Basic .NET - True OOPVisual Basic developers always had the nearly OOP language. You can create classes, sure, but that's about where it stops.

248 Comparison of Visual Basic and Visual BasicComparison of Visual Basic and Visual Basic .NET - Elementary geometry management via the Forms designer One of the true banes of a Visual Basic developer's life has always been writing resize code. Whilst the WinForms paradigm leaves a lot to be desired in the geometry management department in the face of toolkits like Qt (framework)|Qt and GTK+, at least the developer can anchor widgets on forms instead of having to write reams of code in OnResize handlers. https://store.theartofservice.com/the-visual-basic-toolkit.html

274 Microsoft Visual BasicA programmer can create an application using the component-based software engineering|components provided by the Visual Basic program itself. Programs written in Visual Basic can also use the Windows API, but doing so requires external function declarations. Though the program has received criticism for its perceived faults, version 3 of Visual Basic was a commercial success, and many companies offered third party controls greatly extending its functionality. https://store.theartofservice.com/the-visual-basic-toolkit.html

275 Microsoft Visual BasicThe final release was version 6 in Microsoft's extended support ended in March 2008 and the designated successor was Visual Basic .NET (now known simply as Visual Basic). https://store.theartofservice.com/the-visual-basic-toolkit.html

276 Microsoft Visual Basic - Language featuresProgramming in VB is a combination of visually arranging GUI widget|components or GUI widget|controls on a Form (programming)|form, specifying attributes and actions for those components, and writing additional lines of Source code|code for more functionality. Since VB defines default attributes and actions for the components, a programmer can develop a simple program without writing much code. https://store.theartofservice.com/the-visual-basic-toolkit.html

277 Microsoft Visual Basic - Language featuresThough VB programs can be compiled into native code executables #Timeline of Visual Basic (VB1 to VB6)|from version 5 on, they still require the presence of around 1 MB of runtime libraries. Runtime libraries are included by default in Windows 2000 and later. Earlier versions of Microsoft Windows|Windows (95/98/NT), require that the runtime libraries be distributed with the executable. https://store.theartofservice.com/the-visual-basic-toolkit.html

Dialog boxes with less functionality can be used to provide pop-up capabilities. Controls provide the basic functionality of the application, while programmers can insert additional logic within the appropriate event handlers. https://store.theartofservice.com/the-visual-basic-toolkit.html

280 Microsoft Visual Basic - Language featuresUnlike many other programming languages, Visual Basic is generally not case sensitive—though it transforms keywords into a standard case configuration and forces the case of variable names to conform to the case of the entry in the symbol table https://store.theartofservice.com/the-visual-basic-toolkit.html

281 Microsoft Visual Basic - Characteristics* Statements tend to terminate with keywords, such as End If, instead of using s to group statements. https://store.theartofservice.com/the-visual-basic-toolkit.html

282 Microsoft Visual Basic - Characteristics* Multiple variable assignment is not possible. A = B = C does not imply that the values of A, B and C are equal. The boolean result of Is B = C? is stored in A. The result stored in A would therefore be either false or true. https://store.theartofservice.com/the-visual-basic-toolkit.html
