Topic: editor.command()

[sybold]

why does this code work

Code: [Select]

        <CommandMethod("TestSimple")> _
        Public Shared Sub TestSimple()
            Dim ed As Editor = Application.DocumentManager.MdiActiveDocument.Editor
            'call Editor.Command to send command directly
            ed.Command("Line", "0,0,0", "10,10,0", "20,50,0", "")
        End Sub
and this won't, getting einvalidinput

Code: [Select]

       <CommandMethod("TestSimple2")> _
        Public Shared Sub TestSimple2()
            Dim ed As Editor = Application.DocumentManager.MdiActiveDocument.Editor
            'call Editor.Command to send command directly
            Dim savepath As String = "c:\temp\output.zip"
            ed.Command("-etransmit", "c", savepath)
        End Sub

Everytime I set a file path to a string in C#, I have to use double backslashes.

"c:\\temp\\output.zip"

Might not be it.

[sybold]

the path is right, using Commandasync it creates the zip now. but i get a error after its done.

System.NullReferenceException: Object reference not set to an instance of an object.
   at Autodesk.AutoCAD.EditorInput.Editor.CommandResult.Callback()

Code: [Select]

<CommandMethod("TestSimple3")> _
        Public Shared Sub TestSimple3()
            Dim ed As Editor = Application.DocumentManager.MdiActiveDocument.Editor
            'call Editor.Commandasync to send command directly
            Dim savepath As String = "c:\temp\output.zip"
            ed.Commandasync("-etransmit", "c", savepath)
        End Sub

Hi,

I don't know the VB equivalent for async and await C# keywords, but this works:

Code - C#: [Select]

1.         [CommandMethod("TEST")]
2.         public async void Test()
3.         {
4.             Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
5.             await ed.CommandAsync("_.-etransmit", "_c", @"C:\Temp\output.zip");
6.         }

EDIT: this VB syntax seems to work:

Code - vb.net: [Select]

1.         <CommandMethod("TEST")> _
2.         Public Async Sub Test()
3.             Dim ed As Editor = Application.DocumentManager.MdiActiveDocument.Editor
4.             Await ed.CommandAsync("_.-etransmit", "_c", "C:\Temp\output.zip")
5.         End Sub

great!, going to read in this async stuff.

as a command it works, but not within a eventhandler

Autodesk.AutoCAD.Runtime.Exception: eInvalidInput
   at Autodesk.AutoCAD.EditorInput.Editor.CommandAsync(Object[] parameter)

Code: [Select]

Private async Sub docs_DocumentCreated(sender As Object, e As DocumentCollectionEventArgs)
        If (e.Document Is Nothing) Then
            Return
        Else
            AddHandler e.Document.Database.BeginSave, AddressOf Database_BeginSave
            AddHandler e.Document.Database.SaveComplete, AddressOf Database_SaveComplete

            If e.Document.Database.OriginalFileName.EndsWith("dwt") Then
                Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor.WriteMessage(vbLf & "New Document Created - " + e.Document.Name & vbLf)
                Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor.WriteMessage(vbLf & "Used Template - " + e.Document.Database.OriginalFileName & vbLf)
                If e.Document.Database.OriginalFileName.Contains("VSH_Template_") Then
                   ''' load form for customproperties
                   Application.ShowAlertDialog("NEW Drawing with vsh template!")
                End If
            Else
                ''' load form ýes/no backup

                    ''' if yes

                    ''' backup drawing with xrefs
                    Await e.Document.Editor.CommandAsync("-etransmit", "c", "c:\temp\output.zip")
                    ''' Application.ShowAlertDialog("backup created!")
                   
                    ''' else
                    ''' Application.ShowAlertDialog("no backup created!")
            End If
        End If
    End Sub

Correct; your event handler is attempting to call a command in Application context, which is causing the exception... For that you might instead consider using SendStringToExecute().
