Read From/Write To AutoCAD Drawings that are not open

Some of the standard autocad commands edit or read information from drawings that are not open. Is there any way to do this with autocad api? I have many commands that simply read values from a couple of blocks. It would be nice to not have to open the drawing each time.

Or, to do this, does one need to be able to decipher the machine language in a .dwg notepad file?

Thanks,

With AutoCAD .NET APIs, you can open (in AutoCAD process' memory, not visually in AutoCAD Ediotr) a drawing file as side database and then manipulate the data in the database. as long as the code does not use the functionalities related to AutoCAD editor. Something like:

using (var db=new Datbase(true, false))

{

db.ReadDwgFromFile ("{file name]", ..., ...)

// you may or may not want to set this DB as WorkingDatabase here

DoSomethingToTheDb(db);

// You may or may not want to save changes made to the DB (Dwg File, eventaully)

}
