In dem man die Eigenschaft TEXTSTRING des Attributobjectes ändert. Zum Attributobjekt kommt man über die Methode "getattributes" des Blockreferenzobjektes... aus dem array muß sich dann das gewünschte Attribut herausfiltern.
guck dir dazu mal das "GETATTRIBUTES EXAMPLE" aus der Hilfe an.
Sub Example_GetAttributes()
' This example creates a block. It then adds attributes to that
' block. The block is then inserted into the drawing to create
' a block reference.
' Create the block
Dim blockObj As AcadBlock
Dim insertionPnt(0 To 2) As Double
insertionPnt(0) = 0#: insertionPnt(1) = 0#: insertionPnt(2) = 0#
Set blockObj = ThisDrawing.Blocks.Add(insertionPnt, "TESTBLOCK")
' Define the attribute definition
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
height = 1#
mode = acAttributeModeVerify
prompt = "Attribute Prompt"
insertionPoint(0) = 5#: insertionPoint(1) = 5#: insertionPoint(2) = 0
tag = "Attribute Tag"
value = "Attribute Value"
' Create the attribute definition object in model space
Set attributeObj = blockObj.AddAttribute(height, mode, prompt, insertionPoint, tag, value)
' Insert the block
Dim blockRefObj As AcadBlockReference
insertionPnt(0) = 2#: insertionPnt(1) = 2#: insertionPnt(2) = 0
Set blockRefObj = ThisDrawing.ModelSpace.InsertBlock(insertionPnt, "TESTBLOCK", 1#, 1#, 1#, 0)
ZoomAll
' Get the attributes for the block reference
Dim varAttributes As Variant
varAttributes = blockRefObj.GetAttributes
' Move the attribute tags and values into a string to be displayed in a Msgbox
Dim strAttributes As String
Dim I As Integer
For I = LBound(varAttributes) To UBound(varAttributes)
strAttributes = strAttributes & " Tag: " & varAttributes(I).TagString & _
" Value: " & varAttributes(I).textString & " "
Next
MsgBox "The attributes for blockReference " & blockRefObj.name & " are: " & strAttributes, , "GetAttributes Example"
' Change the value of the attribute
' Note: There is no SetAttributes. Once you have the variant array, you have the objects.
' Changing them changes the objects in the drawing.
varAttributes(0).textString = "NEW VALUE!"
' Get the attributes
Dim newvarAttributes As Variant
newvarAttributes = blockRefObj.GetAttributes
' Again, display the tags and values
strAttributes = ""
For I = LBound(varAttributes) To UBound(varAttributes)
strAttributes = strAttributes & " Tag: " & varAttributes(I).TagString & _
" Value: " & varAttributes(I).textString & " "
Next
MsgBox "The attributes for blockReference " & blockRefObj.name & " are: " & strAttributes, , "GetAttributes Example"
End Sub
