If you are building a .NET application and you are struggling to find a way to host Word documents, Excel spreadsheets, PowerPoint presentations, Visio drawings orProject files, you might consider using the Visual C++ ActiveX Control for hosting Office documents.
I learned about this download resource and I was shocked to see how you can add it to your solution and start working with Office applications in less than a minute. You can open Office applications, format content, update documents, save changes, print, and more inside your application.
The EDraw Office Viewer Component is an Active X control written in MFC. The download includes some sample codes to use it inside Visual Basic, HTML pages, C#, Asp.NEt. You can also enable and disable specific functionality by using a full set of properties, methods, and events exposed for customization.
EDraw Office Viewer Component contains a standard ActiveX control that acts as an ActiveX document container for hosting Office documents (including Microsoft Word, Microsoft Excel, Microsoft PowerPoint, Microsoft Project, and Microsoft Visio documents) in a custom form or Web page. The control is lightweight and flexible, and gives developers new possibilities for using Office in a custom solution.
This activeX control is designed to handle specific issues that make dificult the handling of ActiveX documents from a non-top-level host window. Serves as a starting place for constructing your own embedded object file viewer or editor as an ActiveX control.
