Updating this question for the year 2013..!

.cuix files made in Autocad 2013 still seem to work in 2010.  Is this behaviour guaranteed?  Will it continue to be guaranteed with 2014, 2015 etc..?

Where can i find DynDraw.arx for autocad2014 version ?
thanks a lot.

As usually last version of DynDraw can be downloaded from http://www.maestrogroup.com.ua/support/dyndraw.zip
DynDraw2013x32.arx and DynDraw2013x64.arx have to work with AutoCAD 2014.

I am trying to insert a Dynamic block and manipulate its parameters programmaticaly:  'width', 'length', etc...
The block has linear parameters and stretch actions.  After inserting the block, how can I, by using lisp, update the specific parameters value to get it properly displayed
Your support is really appreciated. Thanks

I'm seeing more and more people complain about these things. None of the "solutions" are perfect, and some are lots of work - usually in a inverse-relationship.

Here're the solutions I've seen so far (listed from least work and least possibility of success):
(1) The issue with such "hacked together" driver is that it needs to be done to each workstation. And of course could easily be messed up on one or more through a slight mistype / some other setting which might differ.

(2) Could you perhaps use DotNet to connect to the DB? I think the DotNet connections don't worry about 32/64 bit incompatibilities. You could add some lispfunctions in your DotNet DLL so your lisps handle the DWG and UI interaction with ACad, and the DLL only handles linking, sending & retrieving data from the DB.

(3) Or could you translate your DB from Access to something else? If you don't want to install a server on a dedicated machine and want to stick with a normal file based DB, then you could try using DBase / Paradox files instead - there are ODBC drivers for those, and (especially DBase) has many import / export filters in nearly all programs.

(4) Or try SQLite through nullptr's awesome tool: http://www.theswamp.org/index.php?topic=28286.45

(5) I'd avise using a true DB Server instead of Access (or some other file-based DB) if you're going to have more than one person linking to it at once (I've had numerous issues with corrupt MDB files due to multiple concurent edits). Perhaps try something like Ms-SQL Server Express, or MySQL, or PostGre, or FireBird, or any of a number of others (I prefer PostGre / FireBird as it's Open Source and free, has more control than even MS-SQL, and can run on any operating system {Win/Linux/Mac/BSD/Unix} - so the "server" could be some old PC brought to life again).

Note that even Access can be used as the client side into any of these DB servers - so you could still use the forms / reports / queries you've built in Access to work with your data. It's just that your tables would be linked tables instead of directly saved into the MDB file. Or you could use LibreOffice Base instead of Access, as its got native drivers for most of these as well as ODBC / JDBC drivers if not native - another free program which runs on any OS.

My next try show that I get a dialog, where I can "Add" something in the dialog. But if I press than ok the dialog close with "error: bad argument type: stringp nil"
I want that the dialog still show new adding things.

[Edit]
Type in "test", it must open dialog "Notes" and than try to add something. Here I need help.
After typing new values in Add-dialog I want show values in dialog "Notes" (how).
