程序界面通过 CogRecordDisplay 控件显示视觉运行结果图像。

按指定图像显示，代码如下：

using System;
using System.Windows.Forms;
using Cognex.VisionPro;
using Cognex.VisionPro.ToolBlock;

    /// <summary>  
    /// 显示指定视觉图像  
    /// </summary>  
    /// <param name="cogdisplay">显示控件</param>  
    /// <param name="cogImage">显示图像</param>  
    public void ShowDisplayByImage(CogRecordDisplay cogDisplay, CogImage8Grey cogImage)  
    {  
        try  
        {  
            cogDisplay.Image = null;  
            cogDisplay.StaticGraphics.Clear();  
            cogDisplay.InteractiveGraphics.Clear();  
            cogDisplay.Image = cogImage;  
            cogDisplay.AutoFit = true;  
        }  
        catch (Exception ex)  
        {  
            MessageBox.Show("图像显示失败！");  
        }

    }

按指定VisionPro 工具包 CogToolBlock 内的工具序号显示该工具结果图像，代码如下：

using System;
using System.Windows.Forms;
using System.IO;
using Cognex.VisionPro;
using Cognex.VisionPro.ToolBlock;

    /// <summary>  
    /// 显示工具图像  
    /// </summary>  
    /// <param name="CogTB">显示工具文件</param>  
    /// <param name="cogdisplay">显示控件名称</param>  
    /// <param name="ShowSubRecordsIndex">视觉工具序号</param>  
    public void ShowDisplayByTool(CogRecordDisplay cogDisplay, CogToolBlock CogTB, int ShowSubRecordsIndex)  
    {  
        try  
        {  
            cogDisplay.Image = null;  
            cogDisplay.StaticGraphics.Clear();  
            cogDisplay.InteractiveGraphics.Clear();  
            if (CogTB != null)  
            {  
                cogDisplay.Record = CogTB.CreateLastRunRecord().SubRecords\[ShowSubRecordsIndex\];//按序指定工具图像  
                //cogdisplay.Record = CogTB.CreateLastRunRecord();//最后一张  
                cogDisplay.AutoFit = true;  
                cogDisplay.Fit();  
            }  
            else  
            {  
                MessageBox.Show("显示工具文件不存在！");  
            }  
        }  
        catch (Exception ex)  
        {  
            MessageBox.Show("图像显示失败！");  
        }

    }
