Place to save global data

[KN_Michael 0]

We are currently saving some global data like some settings and also our internal file version inside the drawing header. The file version is used to convert our own data between our code versions.

 

We have problems though with this solution with referenced files and also with working files. Whenever a referenced file is updated or we call refresh inside a working file, we must convert the new data from the referenced file or the project file if we are in a working file. Yes, this data can't be saved, but we must update it temporarily so that our tools and plugins continue working because they are designed in way in which they expect all data to be updated to the newest version.

 

We run our conversion routine whenever the current document is changed, a new file is opened and also if a reference is refreshed or a working file is refreshed.

 

Problem

We can't access the drawing header of the referenced file or from the file that belongs to the objects that are refreshed in a working file, but we would need to know what the file version is there to decide, which convert function we must run on those refreshed objects.

 

Question

Is there another way to save file based data even if we are using referenced files and project files?

For exactly the same reason I did save this data within the plug-in itself. I attached the data to the object handle itself or using parameters.

Because the objects are accessible you can determine versions etc..

We do this as well but in some old plugins (older than 10 years) we did not do this yet. And additionally we sometimes make conversions that do not depend on the objects version but on the files version (some global conversions)..

You can use record formats for storing data and browse via resource lists. I believe the record format can't be hidden to show up in the resource list.

For referenced files, you may be able to access resources, though.
