I am trying to experiment with the demo version of iCalendar.
Using .Net I am able to create a project and add a reference to the dll Aspose.iCalendar.dll
But in vb 6, I am unable to reference the same dll. . Is this dll compatable with vb6 or am I making some mistakes?
Aspose.iCalendar is a .NET component and you should be using VB.NET or C# normally.
VB6 can reference COM components only.
It is possible to use Aspose components from COM clients such as VB6, although it is not as easy as just using them from .NET. For more info see this article, it is for Aspose.Word, but the same concept applies http://www.aspose.com/Wiki/default.aspx/Aspose.Word/AccessingComponentFromCOMClients.html
