Do you know the name "Sean Dotson"?

As far as I know he is a real guru of all things related to programming AutoCAD. I think he does consulting, and probably some gratis tips and helpful hints if you contact him.

Here is his web site: http://www.seandotson.net He has a contact link listed on the site. If he doesn't know the answer, he may be able to tell you where to look for help.

and...

You can find a discussion forum that he runs here: http://www.mcadforums.com/forums/ It seems to mostly be about AutoDesk Inventor (the 3D package), but anyone who frequents that forum probably also has a lot of experience in programming AutoCAD also.


Good luck.




>I have an AutoCAD ObjectARX (C++) and .NET (C#) application that connects to both Access via the JET engine and VFP databases via the VFP OLEDB driver (vfpoledb.1). In 64bit Windows there is now a 64bit Access driver available so I just need to modify the C++ code to use that driver instead of the old one, a simple change to a connection string. The problem is that there is no such 64bit driver available for FoxPro. Microsoft's "solution" is 'run it in 32bit mode', see Ximy's reply at http://social.msdn.microsoft.com/forums/en-US/adodotnetdataproviders/thread/6bcde49e-1532-4e87-aef3-ee24cbc18225, Cindy Winegarden's reply at http://www.vistax64.com/vista-general/22170-odbc-vista-foxpro.html and Cetin's reply at http://social.msdn.microsoft.com/Forums/en-US/visualfoxprogeneral/thread/272f47cf-a02a-4aa4-b4e5-a345921b9553 ("You can't access VFP data over VFPOLEDB using 64 bits calls. However, you can use VFPOLEDB in 64 bits OS (provided calling party is not 64)")
