machinename

基本解釋

Passing a Null String as the MachineName parameter identifies the local machine.
如果傳遞一個空字符串作為計算機名稱參數(shù)，標識的是本地計算機。
ConnectOPC_AE will establish a connection to the OPC Alarms &Events Server specified by MachineName and ServerName.
AE會建立一個和OPC警報/事件服務(wù)器的連接，此連接由計算機名稱和服務(wù)器名稱指定。
On a stand-alone instance of SQL Server, this value remains constant and returns the same value as the MachineName property.
在SQL Server的獨立實例上,該值保持不變,并返回與MachineName屬性相同的值。
This function returns a valid HANDLE if a connection could be established to the OPC Server defined by MachineName and ServerName.
如果一個由計算機名稱和服務(wù)器名稱定義的和OPC服務(wù)器之間的連接可以被建立，則此函數(shù)返回一個有效的HANDLE。
