Update Table's Data Link Values

[Anonymous]

Is there a way to update a table's data linked values through VBA? I see to datalink classes, but all their members are constants. And I don't see anything in the table's class. Is there a library I'm missing?

I am working on an batch script to update the data links in multiple files. Untill now i have this:

NewDoc.SendCommand "DATALINKUPDATE" & vbCr & "U" & vbCr & "K" & vbCr

Which works fine on files whith data links, but when there are non the last K should not be executed. So i am searching for an check if there are data links in the file. Could anyone have an clue where to find them?

Try testing the following condition in order to see whether there are data links or not:

AutoCAD.AcadApplication.ActiveDocument.Dictionaries.Item("ACAD_DATALINK").count > 0

You may need to set a VBA project reference for the 'AutoCAD 2019 Type Library' library (stored @' C:\Program Files\Common Files\Autodesk Shared\acax23enu.tlb' on my computer), to get the above code to work.

Your NewDoc.SendCommand... code seems inelegant. Do you not have a better way to modify data links for live open unsaved AutoCAD 'projects'?

Thanks,
