    Default How to wait for AutoCAD to be ready?

    If I run the "OpenDrawing" from a command prompt inside of AutoCAD (after AutoCAD is "ready") everything works perfectly. However, if I try to run the "OpenDrawing" subroutine as part of the "autoload" functionality I get most of the message boxes, but the drawing doesn't open. I feel this is because AutoCAD is not "all the way open" when the subroutine executes. Does anyone have an idea how to resolve this issue?

    Imports System.Windows.Forms
    Imports Autodesk.AutoCAD.Runtime
    Imports Autodesk.AutoCAD.ApplicationServices
    Imports System.IO
    Public Class clsInitialize
        Implements Autodesk.AutoCAD.Runtime.IExtensionApplication
        Public Sub subInitialize() Implements IExtensionApplication.Initialize
            MsgBox("Plugin loaded successfully . . .")
            OpenDrawing()   'IF THIS LINE IS OMITTED,
        End Sub
        Public Sub subTerminate() Implements IExtensionApplication.Terminate
            MsgBox("Plugin unloaded . . . ")
        End Sub
        <CommandMethod("OpenDrawing", CommandFlags.Session)> _
        Public Sub OpenDrawing()
            Dim strDrivePathNameExt As String
            Dim colAcadDocs As DocumentCollection   'ApplicationServices
            MsgBox("OpenDrawing Sub")
            strDrivePathNameExt = "C:\Temp\Junk.dwg"
            colAcadDocs = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager
            If (File.Exists(strDrivePathNameExt)) Then   'System.IO
                DocumentCollectionExtension.Open(colAcadDocs, strDrivePathNameExt, False)
                MsgBox("File " & strDrivePathNameExt & " opened.")
                MsgBox("File " & strDrivePathNameExt & " does not exist.")
            End If
        End Sub
    End Class
