建立如图所示的作业：
在脚本中 public class UserScript : CogToolGroupBaseScript{ }内添加变量：
1 private double Distance = 0; 2 private CogDistancePointPointTool DistancePointPointToolObject;
在脚本GroupRun构造函数下添加代码：
1 DistancePointPointToolObject = (CogDistancePointPointTool) toolGroup.Tools["CogDistancePointPointTool1"]; 2 Distance = DistancePointPointToolObject.Distance;
在脚本中ModifyLastRunRecord构造函数添加代码：
1 public override void ModifyLastRunRecord(Cognex.VisionPro.ICogRecord lastRecord) 2 { 3 CogGraphicLabel ResultLabel = new CogGraphicLabel(); 4 string labelStr = string.Format("Distance={0:F2} pixel", Distance); 5 ResultLabel.SetXYText((DistancePointPointToolObject.StartX + DistancePointPointToolObject.EndX) / 2, DistancePointPointToolObject.EndY, labelStr); 6 ResultLabel.Color = Cognex.VisionPro.CogColorConstants.Green; 7 toolGroup.AddGraphicToRunRecord(ResultLabel, lastRecord, "图像转换_CogImageConvertTool1.OutputImage", "script"); 8 }
完成代码如下：
1 using System; 2 using Cognex.VisionPro; 3 using Cognex.VisionPro3D; 4 using Cognex.VisionPro.ToolGroup; 5 using Cognex.VisionPro.Dimensioning; 6
7 public class UserScript : CogToolGroupBaseScript 8 { 9 private double Distance = 0; 10 private CogDistancePointPointTool DistancePointPointToolObject; 11

23 // Run each tool in the tool group using the RunTool function
24 for (Int32 toolIdx = 0; toolIdx < toolGroup.Tools.Count; toolIdx++) 25 toolGroup.RunTool(toolGroup.Tools[toolIdx], ref message, ref result); 26
27 // Returning False indicates we ran the tools in script, and they should not be 28 // run by VisionPro
