Can I use ObjectDBX to "read" an opened drawing?

[bim3d]

I am new to ObjectDBX. I've made some codes working using ObjectDBX to read attributes from BlockReferences defined in a drawing.


Set objDBX = GetInterfaceObject("ObjectDBX.AxDbDocument.17")
objDBX.Open ("U:\_Michael\DBX_test2.dwg")

My routine runs fine when the file I'm trying to read is not currently open. Otherwise, I get the following error: "Run-time error ' -2147467259(80004005)': Method 'Open' of object 'IAxDbDocument' failed".

But we have the need to read attributes from an open drawing. Am I reaching a dead end with ObjectDBX in this case? Any ideas are greatly appreciated.

You need to open the file as read-only. I wrote a class for working with dbx and this has an error handler for this case. See this post to download the class.

Thanks a lot. I finally got the "ReadOnly" to work following your code example. This forum is great!
