' Begin the selection
Dim returnObj As AcadObject
Dim basePnt As Variant
On Error Resume Next
' The following example waits for a selection from the user
ThisDrawing.Utility.GetEntity returnObj, basePnt, "Select an object"
If Err 0 Then
Err.Clear
MsgBox "Program ended.", , "GetEntity Example"
Exit Sub
Else
returnObj.Update
MsgBox "The object type is: " & returnObj.EntityName, , "GetEntity Example"
returnObj.Update
End If
当正确选择实体后,Err是为0的,由此判断. |
