Aveva Marine VBNET 编程系列===>读取drawing explorer的第一层级 view

发布时间 2023-10-01 13:29:56作者: 南胜NanSheng

今天我们研究下读取drawing expolrer的第一层级：view

下面的图纸的层级目录示意图，我们今天需要获取所有的view

 

主要用到2个方法：

1# 获取第一个元素

MarDrafting.ElementChildFirstGet Method (）

 

2# 获取相邻的元素

MarDrafting.ElementSiblingNextGet Method 

 

Imports Aveva.ApplicationFramework.Presentation
Imports Aveva.Marine.Drafting
Imports Aveva.Marine.UI ' marAPI.dll
Imports Aveva.Marine.Utility ' marAPI.dll

Imports System.IO
Imports System.Reflection
Imports System.Windows.Forms

Public Class 读取DrawingExplorer
    <MyAmFunctionAtt(NameOf(读取DrawingExplorer), NameOf(读取视图名称))>
    Public Sub 读取视图名称(wm As WindowManager)
        Try
            Dim amEnv As New AmEnvironment()
            '检查是否已经开了图纸
            If Not amEnv.DraftApp.DwgCurrent() Then MsgBox("当前未开启任何图纸,结束命令!", MsgBoxStyle.Critical) : Exit Sub
            '读取第一个view
            Dim vh As MarElementHandle, index As Integer = 1
            Try
                vh = amEnv.DraftApp.ElementChildFirstGet()
                amEnv.MarUI.MessageNoConfirm($"第{index}个view的名字是:" + amEnv.DraftApp.SubpictureNameGet(vh) + Environment.NewLine)
                index += 1
            Catch ex As Exception
                MsgBox("图纸中无任何内容!", MsgBoxStyle.Critical) : Exit Sub
            End Try
            '读取第2个view
            Dim nextVh As MarElementHandle
            Try
                nextVh = amEnv.DraftApp.ElementSiblingNextGet(vh)
                amEnv.MarUI.MessageNoConfirm($"第{index}个view的名字是:" + amEnv.DraftApp.SubpictureNameGet(nextVh) + Environment.NewLine)
                index += 1
            Catch ex As Exception
                MsgBox("图纸中无任何内容!", MsgBoxStyle.Critical) : Exit Sub
            End Try
            Dim errFlag As Boolean = True
            Do
                Try
                    nextVh = amEnv.DraftApp.ElementSiblingNextGet(nextVh)
                    amEnv.MarUI.MessageNoConfirm($"第{index}个view的名字是:" + amEnv.DraftApp.SubpictureNameGet(nextVh) + Environment.NewLine)
                    index += 1
                Catch ex As Exception
                    errFlag = False
                End Try
            Loop While errFlag
        Catch ex As Exception
            MsgBox(ex.StackTrace)
        End Try

    End Sub
End Class

程序运行结果如下：
