    Great Migrations has released gmStudio V9.85. gmStudio is a programmable VB6/ASP/COM re-engineering tool that enables an agile tool-assisted rewrite methodology and helps teams dramatically lower the total cost, risk, and disruption of ambitious migration projects without sacrificing quality, control...
  • Blog Post: ClickOnce and Security

    ClickOnce deployment is another area where Code Access Security needs to be kept in mind. ClickOnce deployments will often be used to deploy Visual Basic .NET (or hybrid Interop Toolkit) applications from a website or network file share. In these cases, the applications don't get the standard Full Trust...
  • Blog Post: Introducing code obfuscation

    If you recall from an earlier post, I said that the main reason for signing an assembly and giving it a strong name was to prevent it being tampered with. For example, many of the assemblies that make up the .NET framework itself are strong-named assemblies that sit in the GAC. If I disassembled one...
  • Blog Post: Code Access Security in action – calling Unmanaged Code

    The following is an example of how code access security might affect your code when calling unmanaged code. Unmanaged code is a posh way of saying “It isn’t .NET code, it is the stuff you used to write before .NET” :-) In VB6 making a call to a Windows API function wasn't affected by any security settings...
  • Blog Post: Authenticode and ActiveX controls

    For VB6 developers, one area where asymmetric keys and digital signatures cropped up was the requirement to sign downloadable ActiveX controls using Authenticode. The idea was to sign the controls using a digital signature so that the origin of the control could always be established. There are a couple...
  • Blog Post: Cryptography

    The second big security area in the .NET framework after Authentication and Authorisation is cryptography. Again, the framework contains a lot of powerful functionality, and again there is an application block that makes it all a bit easier to use. The classes and namespaces that deal with cryptography...
  • Blog Post: Authentication and Authorisation

    As promised , the first in a series of posts about security relevant to a developer new to .NET (such as a VB6 developer). These are what most people will immediately think of when security is discussed. Authentication This is proving your identity by some means, whether it's knowing your password, having...
  • Blog Post: Visual Basic .NET and Security – a few posts are required

    One of the reasons for moving to VB.NET from VB6 may be the more advanced security models available in the .NET Framework - this is particularly relevant in the ASP.NET world where many .NET applications will need a security system. In the desktop arena, there may also be requirements for security features...
  • Blog Post: Virtualization and Visual Basic 6.0 applications

    There may be some circumstances where upgrading a VB6 application is not feasible, for example it may rely on a control that simply does not work in the target operating system. I came across a couple of articles on MSDN that discussed the ways that virtualisation technologies can be applied to this...
  • Blog Post: In VB6 we had the API Viewer, In VB .NET you get the P/Invoke Interop Assistant

    VB6 programmers will remember a useful little utility called the API Viewer, the helped out when you needed to make a Windows API call. There is now an equivalent tool for .NET, the P/Invoke Interop Assistant ( http://www.codeplex.com/clrinterop ). Not surprisingly it does a little bit more, so as well...
  • Blog Post: Enhancing your VB6 Application with Interop

    I’ve been having a look at some of the samples on the Visual Basic Resource Center to see what’s possible when we start using interop between VB6 and .NET. Here are some of my favourites. This article, “Sharing ADO Recordsets Between Visual Basic 6 and Visual Basic 2005” , looks at approaches to sharing...
  • Blog Post: That old friend Binary Compatibility – and a FREE eBook on COM Interop

    A favourite topic for VB6 programmers! Adding a reference to a COM component in Visual Studio adds a reference to a specific version of the VB6 component, so rebuilding the VB6 component without binary compatibility will break the .NET project (you’ll have to re-add the reference to fix it). Switching...
  • Blog Post: VB6 Migration tools are not as expensive as you might think

    How long would it take you to manually convert 50,000 line of Visual Basic 6.0 code to Visual Basic .NET. My guess is… quite a long time :-) However two of the key partners in this space have special versions of their enterprise class tools targeting 50,000 and below for a great price. Code Architects...
  • Blog Post: Aberdeen Group report on Migrating from VB6 to .NET

    Aberdeen Group have created a new report “ Migrating from VB6 to .NET: The challenge of software agility in a volatile economy ” Some bits that stood out for me: 50% will migrate all the applications, 36% will migrate some (86% in total will migrate) “Best in class” understand the importance of external...
  • Blog Post: Visual Basic 6.0 Migration – due diligence is a good thing

    Choice in general is a good thing. When faced with moving a Visual Basic 6.0 application to .NET there is plenty of choices to be made. One of those choices is “Which tool should I go with to migrate the code?”. My advice in general is “Try as many as you can on a representative chunk of your application...
  • Blog Post: About to start a weeks holiday – final post, try a VB6 migration tool for free

    Just about to start a weeks holiday but wanted to get this one last link out there. Artinsoft have released a trial version of their Visual Basic Upgrade Companion Developer Edition. The trial version will allow you to convert up to 2,000 lines of code at a time and is valid for a period of 1 month....
  • Blog Post: UK Visual Basic 6.0 Migration Case Studies – 800K LOC moved to C#

    I have worked on and off with UK company Vertex for 13 years and like many large companies, some of their applications contain code that I first saw 13 years back – Visual Basic 6.0 code. Recently they managed to ensure compliance and business continuity by upgrading not one, but two of their mission...
  • Blog Post: Support statement for Visual Basic 6.0 updated for Windows 7

    I have been asked many times in the last few weeks about Windows 7 and VB6. The support statement has been updated to cover Windows 7 and the news is good. Windows 7 Since the initial release of this support statement, the Windows 7 operating system has been announced.  This document has been updated...
  • Blog Post: Results of Visual Basic Survey (UK)

    In January we created a survey to understand how folks were using Visual Basic 6.0 and Visual Basic .NET in the UK. This survey was sent out to individuals we “suspected” had Visual Basic 6.0 heritage but it was also widely advertised through the UK MSDN Flash to UK developers. We got plenty of great...
  • Blog Post: Visual Basic Upgrade Wizard vs 3rd Party Migration Tools

    [If you are UK based, check out www.microsoft.com/uk/vbmigration for more information ] A question I get asked a lot is “Are 3rd party migration tools really that much better than the free upgrade wizard from Microsoft?” Lets me be perfectly candid. Whilst I always recommend people should try the free...

  • Blog Post: New article on extending VB6.0 applications with the Interop Forms Toolkit 2.0

    I just wanted to swiftly share some useful links if you choose to extend a Visual Basic 6.0 application including a new article I commissioned in the UK – which turned out rather good. Firstly links to the toolkit download and some of the best existing articles. The Interop Forms Toolkit 2.0 which you...

  • Blog Post: VB6 Interop and TlbImp vs AddRef

    I’d always assumed that creating a Runtime Callable Wrapper by adding a reference to the COM component in Visual Studio would generate the same interop code as was generated by using the command line tool TlbImp. That would seem not to be true in at least one case that I’ve discovered, take this VB6...
  • Blog Post: Heads up – The VB6 upgrade guide was written before we released the Interop Forms Toolkit

    I have been re-reading the ”Upgrading Visual Basic 6.0 Applications to Visual Basic .NET and Visual Basic 2005” guide lately which discusses phased migrations where individual application components are upgraded independently (which I prefer to call “Extending with .NET”). This approach relies on COM...
