VB Migration Partner is an innovative VB6 conversion software created by a team
of renowned VB and .NET experts led by Francesco Balena, MSDN Regional Director
and author of the "Programming Microsoft Visual Basic" series (Microsoft Press),
the most complete and authoritative guides to VB language. VB Migration Partner
supports all the main VB6 features and controls, and delivers VB.NET applications
with significantly fewer compilation and runtime errors than those produced by other
conversion tools. Our tests on hundreds of randomly chosen open source applications
show that VB Migration Partner correctly converts 999 out of one thousand statements.
The promotional campaign with Microsoft UK has ended

to VB.NET.
VB Migration Partner can handle VB6 project groups as well as constructs
that have no direct equivalent in the .NET Framework world. The code generation
module and the powerful refactoring module emit VB.NET code that rivals in quality
with code written by expert .NET developers. Even better, developers can customize
the resulting VB.NET code and can improve the behavior of the converted application
while keeping it in sync with the original VB6 project, thanks to our support for
the convert-test-fix cycle. In spite of all this power, VB Migration
Partner is 5 to 8 times faster than the Upgrade Wizard included in Visual Studio.
VB Migration Partner owes its superior performance to three factors.
First, a state-of-the-art parser is able to correctly convert language
constructs that are commonly considered as impossible to migrate automatically,
including:
- arrays with LBound <> 0
- “As New” variables with true auto-instancing semantics
- default members in both early- and late-bound mode
- fixed-length strings and arrays thereof
- Gosub, On Goto, On Gosub keywords
- Declare statements with As Any and delegate parameters
- user controls, MTS/COM+ components, persistable and bindable classes, and more
Second, an advanced code generation engine delivers high-quality
VB.NET code using code-analysis and refactoring techniques, such as:
- deterministic finalization for IDisposable objects
- automatic initialization of Type blocks that contain arrays and As New objects
- conversion of old-styled error handling code (On Error statement) to structured
exception handling (Try-Catch statement) if possible
- transformation of GoSub keywords into calls to separate methods
- detection of ByRef parameters that can safely use by-value semantics (if requested,
the ByVal keyword can be inserted automatically)
- other basic refactoring features, including nested IFs merging, transforming Exit
Function/Property into Return statements and merging a variable declaration with
its initialization (e.g. Dim k As Integer = 1)
- removal of unused methods and unreachable code portions
Third, a full-featured support library dramatically reduces the
differences between VB6 and VB.NET, ensuring that converted applications run as
intended and supporting advanced VB6 features such as:
- the 60+ controls in the VB6 toolbox, with the only exception of OLE Container and
Repeater
- language objects and collections (App, Screen, Forms, Printer, Clipboard, PropertyBag,
etc.)
- virtually all control properties, methods, and events
- graphic statements, and user-defined ScaleMode settings
- context menus, support for legacy help files
- DAO, RDO, and ADO data binding, including binding to data controls, ADO.Recordset,
DataEnvironment, ADO consumer classes, and user controls that work as ADO data sources
- creation of new controls at runtime, via control arrays or Controls.Add method,
with full support for the VBControlExtender object
- automatic and manual OLE drag-and-drop
Unlike other conversion tools, VB Migration Partner can be customized and fine-tuned
to behave exactly as intended, by means of pragmas. Migration pragmas
are special remarks that you can add to the original VB6 application and that tell
the migration engine how code must be handled during the conversion step. VB Migration
Partner supports over 60 different pragmas to solve most of the challenges that
you face during a complex migration project. VB Migration Partner’s IDE even
guides you through the insertion of a new pragma, using an easy-to-use dialog box
that explains the meaning of each argument. A few carefully chosen pragmas often
allow you to generate VB.NET applications with zero compilation or runtime errors.
In addition to reducing compilation and runtime errors, pragmas promote the
convert-test-fix cycle, a key feature in managing complex migration
initiatives. Large real-world business applications typically require maintenance
and upgrading while the migration process proceeds in parallel. VB Migration Partner
allows developers to convert the application, test the result, and go back to the
VB6 code to add pragmas that reduce or eliminate compilation and runtime errors,
and then re-try the conversion until the VB.NET code works as intended. Developers
are working with a single source base, therefore the VB6 and the .NET versions are
in sync until new features are added to the VB.NET code.
VB Migration Partner is powerful enough to deal with huge, enterprise-level projects.
It supports batch migration processes and can easily handle applications
that are split in dozens or hundreds DLLs by supporting phased migrations of individual
VB6 DLL, thanks to its full support for backward binary compability.
It also support source code control tools – including Visual
Source Safe and Microsoft Team System. Last but not the least, VB Migration Partner
can be fully customized by means of an extension object model that
gives you full control on code generation.
