When creating an MsAccess project I get the following message: Object reference not set to an instance of an object.

Stack trace : -----[Core exception]-------------------- at SD.LLBLGen.Pro.DBDrivers.Access.AccessCatalogRetriever.RetrieveSchemas(String connectionString, IDBCatalog catalogToRetrieve, SchemaFetchFlags fetchFlags) at SD.LLBLGen.Pro.DBDrivers.Access.AccessDBDriver.PopulateSelectedCatalogs(Hashtable callBacks, Hashtable connectionElements, SchemaFetchFlags fetchFlags, Hashtable properties) at SD.LLBLGen.Pro.Gui.Forms.NewProjectWizard.CreateNewProject()

Source : SD.LLBLGen.Pro.DBDrivers.AccessDBDriver

If have other projects with the same kind of database that works fine. I've checked for linked tables, but I don';t have them. Usually its adequate to repair and compact the database, this is not enough. I'm working with version 1.0.2004.2 final

I realy need som help flushed

Is your database file marked read-only?

If you still have the same problem , maybe you can send an empty (no data) copy of your access db, that way we can recreate. btw, what version of access db is it??

The database isn't read only. I've sent an empty DB to Drewes.

Henk, i received your db and looked at it, I got yhe same results, what I tried is to import your db into another access db but leave the realtions out, in that case it wioked, if course you need the relations , but I will have to ask Frans to have a look at this, since I can not do more debugging of the llblgengen pro gui myself, I don't have the source code. This db has quite a number of relations and I guess maybe you exceeded some limit , but I will do more investigation and let you know.

Drewes,

Thanks for your quick response. I'm still working at the database and I'm sure that the number of tables and relations will double.

Henk, could you mail me the db you mailed to Drewes? He's in another timezone so it will take a couple of hours before he's able to respond, and I'm (back) in the same timezone as you simple_smile . Just mail to support AT llblgen.com, you can .zip the .mdb if you want .

Just to quote myself: I've mailed you about the new fix, I'm not sure you received the email, but the access driver has been updated in the drivers section in the customer area.
