I know this has probably been covered before, but I am trying to check in / check out a file with the following macro from a button in solidworks.  I can check files out no problem, but when I try to check them back in it just says I can't because I am not the one that has it checked out.  I am using VSTA / .net.

Imports SolidWorks.Interop.swconst

Imports System

Imports System.Diagnostics

Imports EdmLib

Imports EdmLib.EdmBrowseFlag

Partial Class SolidWorksMacro

    Dim startinfo As New ProcessStartInfo

    Dim Vault As New EdmVault5

    Dim VaultName As String = "PDMWorks Enterprise"

    Dim eFile As IEdmFile5

    Dim parentFolder As IEdmFolder5

     Sub Main()

        Vault.LoginAuto(VaultName, 0)

         eFile = Vault.GetFileFromPath("C:\PDMWorks Enterprise\27849.sldprt", parentFolder)

        Try

            If eFile.IsLocked = True Then     'Check the File back in

                eFile.UnlockFile(0, "API Check In", 2)

                MsgBox("File Successfully Checked In: " & eFile.Name)

            Else                                        'Check the file out

                eFile.LockFile(parentFolder.ID, 0)

                MsgBox("File Successfully Checked Out." & eFile.Name)

            End If

        Catch ex As Exception

            MsgBox(ex.Message & vbLf & eFile.Name)

        End Try

    End Sub
