vb.net - Solidworks EPDM API IEdmEnumeratorVariable5::SetVar 未按预期工作

Question

我正在尝试使用 IEdmEnumeratorVariable5::SetVar 根据用户输入更新一些文件卡变量到 Windows 窗体。我的代码执行，没有错误消息，文件被 checkout 并重新 checkin ，并在历史记录中添加了适当的注释；但是卡上的变量没有更新。

我通过在运行时单步执行代码来验证所有变量都填充了正确的(如预期的)数据。 SetVar程序都顺利进行，但数据卡上的变量不会改变值 - 即使手动刷新文件夹 View 也没有效果。

下面是我的代码。

这是一个加载项应用程序，使用 VS Community 2015 在 VB 中编写为类库项目，目标框架为 .NET 4.0。

努力使这个问题更简洁；下面我只包含了执行设置变量工作的代码片段，然后我还包含了更多代码，以便您可以在需要时获得整个画面。

只是冰山一角 :

这是设置变量工作的代码:

Dim UserManager As IEdmUserMgr5 = .SourceVault
Dim User As IEdmUser5 = UserManager.GetLoggedInUser

CardComment = UserComment & CardComment
CardDate = Today().ToString("yyMMdd", Globalization.CultureInfo.InvariantCulture)
CardBy = User.Name
CardDisposition = UserDisposition

CardVariables.SetVar(DispositionVariable, "@", CardDisposition)
CardVariables.SetVar(CommentVariable, "@", CardComment)
CardVariables.SetVar(ByVariable, "@", CardBy)
CardVariables.SetVar(DateVariable, "@", CardDate)
CardVariables.Flush()

更广泛的笔划:

类模块级变量:

Private Structure CommandInfo
    Dim SourceVault As IEdmVault11
    Dim SourceCommand As EdmCmd
    Dim SourceSelection As System.Array
    Dim TargetTemplate As System.String
    Dim VerifiedPaths As List(Of String)
End Structure

Private ReceivedCommand As CommandInfo

OnCmd 过程(调用者):

Public Sub OnCmd(ByRef poCmd As EdmCmd,
                 ByRef ppoData As System.Array) Implements IEdmAddIn5.OnCmd

    Dim CommandToRun As MenuCommand

    Try

        With ReceivedCommand
            .SourceVault = poCmd.mpoVault
            .SourceCommand = poCmd
            .SourceSelection = ppoData

            'Get the command structure for the command ID
            Select Case poCmd.meCmdType

                Case EdmCmdType.EdmCmd_Menu
                    CommandToRun = AvailableCommands(.SourceCommand.mlCmdID)

                Case EdmCmdType.EdmCmd_CardButton
                    Select Case True
                        Case poCmd.mbsComment.ToString.ToUpper.Contains("DISPOSITION")
                            DispositionRequest()
                        Case Else : Exit Sub
                    End Select

                Case Else : Exit Sub
            End Select
    '...... (End Try, End Sub, Etc.)

DispositionRequest 过程(被调用者):

Private Sub DispositionRequest()

    Dim UserDisposition As String

    Using Disposition As New DispositionForm
        With Disposition
            If Not .ShowDialog() = System.Windows.Forms.DialogResult.OK Then Exit Sub
            Select Case True

                Case .Approve.Checked
                    UserDisposition = "Approved"

                Case .Reject.Checked
                    UserDisposition = "Rejected"

                Case Else : Exit Sub

            End Select
        End With
    End Using



    Dim UserComment As String

    Using Explanation As New DispositionExplanation
        With Explanation

            If Not .ShowDialog() = System.Windows.Forms.DialogResult.OK Then Exit Sub

            If .ListView1.Items.Count > 0 Then
                 'do some stuff not relevant to this question...
            End If

            UserComment = .Comments.Text

        End With
    End Using

    'This next procedure just gets a list of paths from ReceivedCommand.SourceSelection  - which is just the ppoData argument from the OnCmd procedure - see code block above!
    Dim RequestPaths As List(Of String) = GetSelectedFilePaths()

    For Each Path As String In RequestPaths
        With ReceivedCommand
            Dim RequestFile As IEdmFile5 = .SourceVault.GetFileFromPath(Path)
            Dim ParentFolder As IEdmFolder6 = .SourceVault.GetFolderFromPath(System.IO.Path.GetDirectoryName(Path))
            Dim UnlockLater As Boolean = False

            If Not RequestFile.IsLocked Then
                UnlockLater = True
                RequestFile.LockFile(ParentFolder.ID, .SourceCommand.mlParentWnd, CInt(EdmLockFlag.EdmLock_Simple))
            End If

            Dim CardVariables As IEdmEnumeratorVariable5 = RequestFile.GetEnumeratorVariable

            Dim Success As Boolean

            Const CommentVariable As String = "DispComm"
            Const ByVariable As String = "DisposedBy"
            Const DateVariable As String = "DisposedDate"
            Const DispositionVariable As String = "Disposition"

            Success = CardVariables.GetVar(DispositionVariable, "@", CardDisposition)

                Success = CardVariables.GetVar(CommentVariable, "@", CardComment)

来自 the documentation :

bsCfgName : Name of configuration or layout to which to store the variable value; empty string for folders and file types that do not support configurations

我正在使用一个不支持配置的虚拟文件。
我看到一个使用虚拟文件的 C 示例，它们传递空引用，所以我重新阅读文档并看到上面的摘录，所以我将代码从 "@" 更改为至 String.Empty对于 mboconfiguration 参数，现在它正在工作!

CardVariables.SetVar(DispositionVariable, String.Empty, CardDisposition)
CardVariables.SetVar(CommentVariable, String.Empty, CardComment)
CardVariables.SetVar(ByVariable, String.Empty, CardBy)
CardVariables.SetVar(DateVariable, String.Empty, CardDate)
CardVariables.Flush()
