Constant Example

Using Programming Languages other than VBA

Sub Example_Constant()
	' This example creates an attribute definition in model space.
	' It then queries the attribute to see if it is a constant attribute.

	Dim attributeObj As AcadAttribute
	Dim height As Double
	Dim mode As Long
	Dim prompt As String
	Dim insertionPoint(0 To 2) As Double
	Dim tag As String
	Dim value As String

	' Define the attribute definition
	height = 1#
	mode = acAttributeModeVerify
	prompt = "New Prompt"
	insertionPoint(0) = 5#: insertionPoint(1) = 5#: insertionPoint(2) = 0
	tag = "New Tag"
	value = "New Value"

	' Create the attribute definition object in model space
	Set attributeObj = ThisDrawing.ModelSpace.AddAttribute(height, mode, prompt, insertionPoint, tag, value)
	ZoomAll
		
	' Query the attribute
	GoSub QUERYSTATUS

	' Change the attribute
	attributeObj.constant = Not attributeObj.constant
	GoSub QUERYSTATUS

	Exit Sub

QUERYSTATUS:
	If attributeObj.constant Then
		MsgBox "The attribute is a constant attribute."
	Else
		MsgBox "The attribute is not a constant attribute."
	End If
	Return
End Sub
