本例展示了如何在Microsoft .NET Windows应用程序中使用BR.AN.PviServices组件。
1.创建一个新的Windows应用程序项目。
1.将BR.AN.PviServices.dll添加到你的项目引用中。
2.设计你的表格
3.实施

4.至少你必须将 "Sample_01 "项目的输出目录改为你的PVI-Binaries（PVIMan.exe、PVIMon.exe）目录。
5.启动你的PviServices应用程序
备注。
- 任务和它的本地变量--在这里是 "loctask "和 "int_l_var"--必须在目标上存在，以便在目标上的任务/变量和PviServices对象之间建立连接。
