ActiveX and ​.NET controls

The aaHistClientTrend and aaHistClientQuery controls provide the essential functionality of the Historian Client Trend and Historian Client Query. You can use these controls in container applications, such as InTouch HMI software, Visual Studio (Visual Basic .NET or C#), and Internet Explorer. You can also use Historian Client building block controls (such as aaHistClientTagPicker, aaHistClientTimeRangePicker, and so on) in your custom applications.
