VSTO Add-In Development

In this world of technology, the Office platform right now is not only feature-rich but also easily scalable as a platform. Because of the business needs fulfilled by Microsoft Office, developers nowadays need to expose all functionalities in the systems to have rich experience of Office. Office add-ins are used for extension of functions and alteration of office clients, for example, Microsoft Word, Microsoft Outlook, Microsoft Excel, Microsoft PowerPoint and Office 365. Microsoft supports modification of existing features and creation of new features by using available tools and APIs to VSTO add-in development companies.

There are different types of Office add-ins like (1) functionality extension in PowerPoint, Excel, and Word (2) Creation of new object in PowerPoint and Excel (3) Extension of functions in outlook add-ins, etc.

There are mainly two technologies for developing Office add-ins

  • (1) Develop add-in using Office JavaScript API
  • (2) Develop add-in using Visual Studio Tools for Office(VSTO)

iFour Technolab uses latest technologies in order to build superior systems for clients. Our team is experienced and has got expertise in using the latest tools for providing best solutions in the market. We use VSTO add-ins for developing the best software for clients.

VSTO is a set of development tools that is available in the form of add-in or extension (project templates) and it allows Office 2013 and later versions of Office applications to host the add-in and to expose their functionality via .NET framework.

VSTO allows using functionality and user interface from Office applications in .Net applications as well as provides extensions for Office applications to be written in programming languages.

iFour Technolab is one of the versatile VSTO add-in development company in India having vast experience in developing a wide range of solutions. For VSTO based office development, iFour uses the following templates.

  • VSTO add-ins and
  • Document-level customizations

VSTO add-ins:

Whichever features created by the company in VSTO add-ins, are made available to the application itself, irrespective of the documents which are open. Our company builds solutions in such a way that the VSTO add-ins run at a time when the associated application is started, though VSTO add-ins are also be loaded after the application is running already.

iFour team uses numerous tools in order to create VSTO add-ins. In the systems having add-in, a class is already created which represents the VSTO add-ins automatically. This class has events and properties which can be used to access the object model and when the VSTO add-ins are loaded and shut down, code is run in a project. In VSTO add-ins projects at iFour, there are many Visual Studio features available for example an internal debugger and windows forms.

Document level customizations:

Document-level customizations by iFour have an assembly which is associated with a single workbook, template or document in Microsoft Office Excel or Microsoft Office Word. Whenever we open associated document, the assembly is loaded. As well as whichever features are created in customizations, made available when the associated document is open. Because of the customizations application cannot make wider changes, for example, displaying ribbon tab or a new menu when any document is open.

With the help of various tools available in Visual Studio our team creates document-level customizations. The document which is customized is hosted as a design surface in Visual Studio. It enables to design the document just by dragging and dropping controls onto it. iFour Technolab is using numerous features available in Visual Studio such as drag and drop data binding, an integrated debugger and Windows forms controls which results in robust and sustainable solution for client.
