Review and try to reduce your usage of 3rd party VB controls.
#Textinputstream xojo upgrade
If you are using an older version of VB, upgrade your code to a later version before attempting to use VBMA. The code is migrated to the Xojo project, but is completely commented out and is primarily for reference.

Source code is not converted or modified in any way. Since VB forms do not exactly match Xojo windows, VBMA maps VB controls to their equivalent Xojo controls as it migrates the project. VBMA does not create a working Xojo application from VB code. The purpose of this tool is to get your project into Xojo so that you can work on it from a single place. VBMA takes the selected VB project and creates a Xojo XML project file containing the forms, modules, classes and source code from the VB project.

Visual Basic Migration Assistant (VBMA) is a free tool that can help you to begin migrating VB6 and VB.NET code to a Xojo desktop project. Before trying to migrate VB6 code, you should use the OPTION EXPLICIT command to make sure that all your variables are declared. It would infer a type based on a special character in its name (name$ would be a String, for instance). VB6 (and older versions) would allow you to use a variable that had not been previously declared. Xojo is a strongly typed programming language. This is not something that works for cross-platform apps, so Xojo consolidates all file processing into a few classes: FolderItem, TextInputStream, TextOutputStream and BinaryStream. Of course, Xojo can easily create web and iOS apps, something VB6 cannot do.įile input and output in VB6 uses direct, path-based access to files.

Xojo can access DLLs and many ActiveX controls, but using them means your application will only run on Windows and cannot be cross-platform. Since these are all Windows-specific technologies, they are not useful for cross-platform apps. A big difference is that Xojo cannot create DLLs, ActiveX controls or any kind of shared libraries. Xojo definitely feels familiar to VB developers, but there are differences as well. Here is a list of some VB controls and their Xojo equivalents for desktop, web and iOS apps: Of course VB had plenty of additional, but Windows-specific, controls that could be added to its default setup and many of these controls can be added to Xojo using ActiveX, but they will also remain Windows-only. But Xojo also has several controls that are not included by default with VB. The default UI controls included with VB are, for the most part, also included with Xojo. Here is a mapping of some VB data types to Xojo data types:īelow are some common VB commands and their corresponding Xojo commands. For example, Integer is equivalent to a VB6 Long. Someone who has used either VB6 or VB.NET will have no trouble understanding the Xojo programming language.Īlthough Xojo data types are not always named exactly the same as VB6 data types, all the equivalent types are there. You’ll see familiar syntax for If.Then.Else, For.Next, While.Wend, Dim and many other commands. To start with, the language syntax of VB is very similar to Xojo.

Xojo is usually a better choice for Visual Basic 6 apps because it has the simplicity of VB6, but is a fully object-oriented language like VB.NET. NET is large and complex, not to mention not cross-platform. Visual Basic 6 (VB6) is no longer supported by Microsoft, which recommends you instead migrate to Visual Basic.
