Get path of file on clipboard By Adam Nagy
As mentioned in Kean's blog post, when you select entities in a drawing inside AutoCAD and run _COPYCLIP (Ctrl+C) then AutoCAD will WBLOCK out the selected entities into a temp DWG file. The content that's placed on the clipboard will also contain the path to that temp file. In case you would like to use that file, here is one way to find out its path:

Public Function GetClipboardFilePath() As String

  Dim dataObject As IDataObject =

    System.Windows.Clipboard.GetDataObject()

  ' Get the list of available formats

  Dim formats() As String = dataObject.GetFormats()

  For Each format As String In formats

    ' In case of AutoCAD 2013 this would be "AutoCAD.R19"

    If format.StartsWith("AutoCAD.") Then

      Using stream As MemoryStream = dataObject.GetData(format)

        ' Unicode encoding is 16 bit (2 bytes) just like ACHAR

        Using reader As TextReader =

          New StreamReader(stream, System.Text.Encoding.Unicode)

          ' 0..259 = 260

          Dim text(259) As Char

          reader.Read(text, 0, 260)

          ' There will be lots of 0 value characters in the array

          ' that we need to clean up   

          Return New String(text).TrimEnd(New Char(){Chr(0)})   

        End Using

      End Using

    End If

  Next

  Return Nothing

End Function

以下为 ObjectARX 实现, AutoCAD 2004 + XP 测试 OK
命令: mycommand
Ok, temp file= C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\A$C28C724E3.DWG
命令: 指定对角点:
命令: mycommand
No AutoCAD clipboard entity!
