When you load a DVB file that is already loaded you can get this message: File already loaded: C:\yourproject.dvb
To avoid this us vl-vbaload instead of VBALOAD. This way you don't need to bother to know if the DVB file is loaded or not. In the same way vl-vbarun can be used instead of VBARUN. In some AutoCAD versions this is a way to avoid the load macro warning dialog box.

AutoCAD Focus Control for VBA Type Library (AcFocusCtrl16.dll or AcFocusCtrl.dll) found in C:\Program Files\Common Files\Autodesk Shared is useful if you have a modeless form in the VBA project.  Without it the focus does not remain at a modeless form (ShowModal property set to false, available in AutoCAD 2002 and newer versions). Use the Tools menu and add a reference to the AcFocusCtrl16.dll file and then add the AcFocusCtrl by right-clicking for additional controls in the VBAIDE toolbox when you have the form in edit mode. In some cases it can be needed to register the dll file using regsvr32.

Sample to write and read Xrecord values in a Dictionary:

Public Sub WriteXRec()
  Dim oDict As AcadDictionary
  Dim oXRec As AcadXRecord
  Dim dxfCode(0 To 1) As Integer
  Dim dxfData(0 To 1)
  Set oDict = ThisDrawing.Dictionaries.Add("SampleTest")
  Set oXRec = oDict.AddXRecord("Record1")
  dxfCode(0) = 1: dxfData(0) = "First Value"
  dxfCode(1) = 2: dxfData(1) = "Second Value"
  oXRec.SetXRecordData dxfCode, dxfData
End Sub

Public Sub ReadXRec()
  Dim oDict As AcadDictionary
  Dim oXRec As AcadXRecord
  Dim dxfCode, dxfData
  Set oDict = ThisDrawing.Dictionaries.Item("SampleTest")
  Set oXRec = oDict.Item("Record1")
  oXRec.GetXRecordData dxfCode, dxfData
  Debug.Print dxfData(0)
  Debug.Print dxfData(1)
End Sub
