Access DWG SummaryInfo Custom Properties

[Anonymous]

Hi

Would really appreciate any help that anybody can give me on this.

I'm trying to programatically access the Custom Properties of a DWG's SummaryInfo, but am constantly coming up against various errors.

From the examples I've found and the other posts I've come across I have to create a new Database object (Autodesk.AutoCAD.DatabaseServices.Database) but when I do I get the following message.

Dim DB as New Database(False, True)

'AccessViolationException was unhandled'
'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'

As you might have guessed I'm new to .NET having done all my previous work in VBA.

Any help will be very much appreciated.

Cheers

G

You can read the file properties from the outside
without AutoCAD (via the COM APIs provided by
AutoCAD), but you cannot edit them using those
APIs, or via any means outside of AutoCAD.

I don't have any code examples for the former,
and since its entirely COM/ActiveX based, you
might find more information about it in the VBA
newsgroup.

I guess using the ActiveX API is a solution if I want to reach a dwg-file without AutoCAD started. What references should be added for this? And does anyone have any code examples explaining how to read/edit custom dwg file properties that way? I'm trying to solve this using C#, but I'm stuck.

I agree with you that you should be able to access those custom properties outside of AutoCAD. After all, the custom file properties are available to Windows when you right-click the file and choose properties. That doesn't require a .NET dll running inside of AutoCAD to do that so there should be some other basic file header template that allows you to read that information from the file without running AutoCAD. I'm looking for that myself and if I find I I'll post it here.

hi !

this posting is old, but may be interest for my problem.

one line of code is

Dim Dict As Specialized.StringDictionary = sbuild.CustomProperties

visual Studio 2013 give the message "sbuild.CustomProperties will be outdated.

could someone give better code?

DatabaseSummaryInfoBuilder.CustomProperties has been flagged as "Obsolete" since Acad2009 (or Acad2008, or Acad2010, cannot remember). You should use CustomPropertyTable (which is an IDictionary object) instead. Had you simply looked up the AutoCAD .NET API document, you would have found it out easily.
