Use AVEVA Historian Client controls in different environments

There are two versions for each of the AVEVA Historian Client controls: one for use within a ActiveX control containers and another for within .NET containers. ActiveX control containers include Visual Basic, Visual C++, InTouch HMI software, and so on. .NET containers include VB.NET, C#, ASP.NET, and so on.

The ActiveX versions are named according to the following convention:

aaHistClientXXX Control

The .NET versions are named as follows:

ArchestrA.HistClient.UI.aaXXXControl

For example, the Trend control is implemented as two versions: aaHistClientTrend Control and ArchestrA.HistClient.UI.aaTrendControl.

If a container supports both .NET and ActiveX controls, such as Internet Explorer, use the .NET version, since that is the native form of the controls for the AVEVA Historian Client software.
