ComponentOne WebChart comprises four elements:
- Server-side components (2D and 3D) that serve charts as JPEG, PNG or an ActiveX object.
- Design-time controls (2D and 3D) for Microsoft Visual InterDev.
- Optional client-side ActiveX controls.
- An optional temporary file management component.
The two server-side charting components (one for 2D and one for 3D) wrap the current ComponentOne Chart ActiveX controls. The Active Server Page (ASP) communicates with the server-side charting component, which in turn, communicates with the ComponentOne Chart OCX control.
The ASP developer uses ComponentOne WebChart's 2D and 3D design-time controls within Microsoft Visual InterDev. These controls, in turn, interact with the ComponentOne Chart OCX control. To give you a better understanding, here is a pictorial representation of the way the elements fit together.
As end-users interact with ComponentOne WebChart on the server, temporary files are generated and stored in a temporary directory. To prevent this directory from filling up, ComponentOne WebChart provides a small utility component that automatically deletes each temporary file a set time after the last reference to it is released.
