Insert block in multiple documents

[will.wydock]

Hi,

I am trying to create a routine for inserting a block (ie. Record Stamp) into multiple dwg files. I thought I have all the information but I can not get the routine to run. I have tried getting the documents and adding a lock and it still does not seem to make a difference. Is there something that i am missing in my code to do this, or is this even possible?

Thanks in Advance

Hi,

I think the first problem is here:

Document document =  CADApplication.DocumentManager.GetDocument(database);

While using a 'side database' (i.e. new Database & ReadDwgFile) you cannot access to the document of this database (and most of the time you not need to).

The document and document lock was a new add as I could not get it working on just the database. It looks like I went the wrong direction in solving this.

Thank you, I was able to solve my multiple document issue.

When I am running my routine, I am always getting the following errors.

eHadMultipleReaders
at Autodesk.AutoCAD.DatabaseServices.Database.Insert(String blockName, Database dataBase, Boolean preserveSourceDatabase)
at software.Common.BlockInsert.MultiDocInsertBlock() in \\Software\Common\BlockInsert.cs:line 56

from what I have been reading that means that the database has been open and not closed. It does not matter whether I have used an old file or a brand new file that I have created. I am still getting the same error. How do you close a database to make sure that this error doesn't occur?

Thanks,

eHadMultipleReaders is probably due to the using of an OpenCloseTransaction instead of a standard transaction.

This seems to work.
