Description: OPC 历史数据访问代码
从OPC基金会下载的，非常有帮助！-The OPC Historical Data Access Sample Code consists of an C# client application and a C++ server application. These applications implement the Historical Data Access Custom Interface Specification 1.20. These samples are intended to demonstrate the correct operation of the specification and to serve as starting point for vendors who wish to develop their own implementations.
The sample client is based on the OPC HDA .NET API: a standard .NET class library that provides a simplified, .NET aware interface to the OPC COM servers. The OPC .NET API is available as a separate download on the OPC Foundation website and is maintained as an open source library which is available to all OPC Foundation members.
