Anonymous — Wed, 20 Oct 2010 02:39:10 GMT

Hello there. I know How to write to command line in Autocad using vb net.

for example following command write to command line :

DocumentManager.MdiActiveDocument.Editor.WriteMessage(vbNewLine &

"Hello World!" & vbNewLine)

Now my Question is ,how I can read last 10 lines in command line and put them in a variable for later use?

Thanks for any suggestion.

Are you wanting to prompt for the 10 lines?

I don't have time to play, but have a look at this

public static List<string> GetLastCommandLines(int lastLines, bool ignoreNull);

Declaring Type:	Autodesk.AutoCAD.Internal.Utils
Assembly:	acmgd, Version=18.1.0.0

I had to see an actual example but the keywork Kerry provided was helpful and that was exactly what I wanted. Again thank you gentlemen . You helped me to keep my new job.

Regards,

No need to thank me I did not do anything.

But if your job was on the line all you would have to do is post some code or show that you are trying and ask for a code example and I would have tried or someone else would have helped you out.

Here is working code . I simplified it.

 Sub Test()
        Dim commandline As System.Collections.Generic.List(Of String)
        Dim I As Integer
        Dim TempT As String
        ' Get most recent last 10 lines of command lines
        commandline = Autodesk.AutoCAD.Internal.Utils.GetLastCommandLines(10, True)
        For I = 0 To commandline.Count - 1
            TempT = Trim(commandline.Item(I))
            MsgBox(TempT)
        Next
    End Sub
