In the majority of cases, the Visual Basic Upgrade Companion will successfully infer the type of the variables and will automatically add a call to the appropriate function. For instance, the following Visual Basic 6.0 code fragment. ArtinSoft's Blogs! SOFTWARE MIGRATION EXPERTSAfter several months of hard work, we are proud to announce the release of version 2.2 of the Visual Basic Upgrade Companion.

Chapter 6: Understanding the Visual Basic Upgrade Wizard When executing a VB6 to.NET migration project, you should apply tools that automate as much of the conversion as possible. The most accessible of those tools is the Visual Basic Upgrade Wizard, part of the Visual Studio.NET IDE and created by ArtinSoft for Microsoft. To ensure a smooth, efficient migration, it is helpful to understand the upgrade wizard supported features in relation to the Visual Basic 6.0 application. From declarations and properties to modules and interfaces, Chapter 6 describes how the tool manages to upgrade from VB6 to.NET. Also, learn about the characteristics of the resulting code, the VB 6.0 upgrade issues that may occur and the tasks you will need to perform after the upgrade wizard had done its job. • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • How does the Visual Basic Upgrade Wizard works?

The Visual Basic Upgrade Wizard, created by for Microsoft, is an automated source code upgrade tool that upgrades a project written in Visual Basic 6.0 to a series of files written in Visual Basic.NET. It takes into account the different aspects of software creation and transformation, including program organization, statements, expressions, symbols, data types, literal values and variables, creating a new project, copying each file from the original project into the new one, and modifying the files as necessary. Finally, it generates a report detailing what was done and what you need to do to finish the upgrade.

How is the Upgrade Wizard available? The upgrade tool is available in two forms: the upgrade wizard that is integrated into the Visual Studio.NET development environment and a command-line tool that is available with the.NET Framework.

What are the Visual Basic.NET project equivalents or alternatives for VB 6.0 project types? Visual Basic 6.0 Visual Basic.NET Standard EXE Windows Application ActiveX DLL Class Library ActiveX EXE Class Library ActiveX Control Windows Control Library ActiveX Document No direct Equivalent Visual Basic.NET can interoperate with ActiveX Documents DHTML Application No direct equivalent. Use ASP.NET Web Application IIS Application (WebClass) No direct equivalent. Use ASP.NET Web Application When the Upgrade Wizard converts a project, how is the code modified?

• Language changes: The upgrade wizard transforms Visual Basic 6.0 code to use the new keywords and language structures introduced in Visual Basic.NET. Darkest dungeon build 75275. • Core functions: References to Visual Basic 6.0 core functions are upgraded to equivalent classes and methods in the.NET Framework, when possible.

When there are no equivalent.NET functions, or the upgrade wizard cannot determine the function to use, the wizard adds a note to the code file so you can fix it manually. • Forms: Visual Basic 6.0 forms and controls are upgraded to.NET Windows Form Controls equivalents.

• Web classes: Visual Basic 6.0 Web classes are upgraded to.NET Web Forms. • Data: Data and connection objects are upgraded to Visual Basic.NET runtime callable wrappers (RCW) corresponding to data and connection objects. Upgrading these components to ADO.NET requires additional work. • User controls: Visual Basic 6.0 ActiveX user control components are upgraded to.NET user controls. Does the Upgrade Wizard inspect for reference when it upgrades a project? Yes, when the upgrade wizard upgrades a project to Visual Basic.NET, it inspects the code for references to other files in the project, and to any external libraries, components, COM objects, and files.

Considering the limitations of the Upgrade Wizard, is there a way to customize or extend its functionality? No, but there’s an enhanced version (or enterprise edition) of the upgrade wizard called the, developed and sold by, the same company that built the Upgrade Wizard for Microsoft. It can parse database schema definition files to obtain additional information about field data types and produce improved Visual Basic.NET code. This and other enhancements can help you further shorten your upgrade process by automating more of it. It can even be customized to extend its functionality, according to the characteristics of the application to be migrated. Does the Upgrade Wizard provide any type of information after the conversion process? When the upgrade wizard upgrades your project, it generates a report that can be used as a guide for the manual changes that your project requires afterwards.
