Saving and Retriving AcadDictionaries

I have a project that I am working on that I save my data into an
acadDictionary. I need this information in another drawing. I am
looking suggestions/code examples for the best way to save and retrieve
this data.

TIA

AcadDictionaries are stored in a drawing. If you need to
access data across drawings, then it would make sense to
store it externally, perhaps in an XML file or some other
form, no?

Otherwise, you can use ObjectDBX to access data in another
drawing without opening it in the AutoCAD editor.

 

David, this should get you started. I believe this was origianally posted
by Jeff

Public Sub WriteXRecOLD()
Dim mydict As AcadDictionary
Set mydict = ThisDrawing.Dictionaries.Add("Sample")

Dim myXRec As AcadXRecord
Set myXRec = mydict.AddXRecord("Test")

Dim dxfCode(0 To 1) As Integer
Dim dxfData(0 To 1)
dxfCode(0) = 1: dxfData(0) = "Hello?"
dxfCode(1) = 2: dxfData(1) = "Is anybody out there?"
myXRec.SetXRecordData dxfCode, dxfData
End Sub

Public Sub ReadXRec()
Dim mydict As AcadDictionary
Set mydict = ThisDrawing.Dictionaries.Item("Sample")

Dim myXRec As AcadXRecord
Set myXRec = mydict.Item("Test")

Dim dxfCode, dxfData
myXRec.GetXRecordData dxfCode, dxfData

MsgBox dxfData(0) & vbCrLf & dxfData(1)
End Sub

 

Thanks for the code example. I may not have been fully clear in my
question. I use these examples in my code but I need to move the
dictionary to another drawing and need to save the dictionary data to a
file and then retrieve that data in the new drawing. I use the
dictionary just to save the data in the drawing and when my routine runs
it loads a local array with my data. I can replace the dictionary with
a subroutine that reads and writes the data to an INI or XML file. I
found some examples for INI but haven't looked hard for an XML file. I
was wondering before I start which is better to use. My array that my
data is in is a UDT.

Thanks

I think you were clear with your question
Tony posted the solutions possible
The xml sounds like the way to go, though, like you, I have not yet found a
simple tutorial on how to create and read xml files.
from the little i understand about xml that would be the perfect repository
for a udt
I've done a fair amount of googleing trying to find how to incorporate xml
into lisp or vb but havent' found it yet....more time.....
good luck and keep us posted on what you come up with.

without getting into the new territory of an xml the quickest way may be
what tony said about using objectdbx to just copy the dictionary object from
one dwg to another

 

You probably stated it correctly... I didn't read it correctly After
reading it again, Tony's suggestion to write it out to a file then aquire
the data from the file for other drawing(s) seems like the way to go.
