Closing TCursor variables declared within a method
If a variable that is declared within a method goes out of scope at the end of that method, is it really necessary to close a TCursor variable that is declared within a method?

sorry, no help here.. I've never used any of the Corel automated processes, and very rarely have I used any of the Suite pieces other than Paradox itself.. the real problem these days is that there's nobody at Corel who knows anything about the Corel automated processes, either.. new or old

Database Diagraming
Hello All, I am looking for advice on diagramming my paradox database/application.. So far my methods have been really tedious. In Paradox it is easy enough to get the table structures out. For forms I open them in Design, use the object editor to get to the event and open that up for editing. I just read through the code to see where the original developer stored data and what other forms or reports he was calling. In Access I would use the object dependency tool to do this type of work. I have not found anything like that in Paradox 9. Is there anything helpful for mapping dependencies in later versions of Paradox? Are there any other tricks you guys have learnered for mapping out relationships and object dependencies when you are disecting other people's work? Thanks, Steve

look at the enum functions.. enumfilelist can give you a list of tables, then scan that list with enumfieldstruct to build a table of field names and properties enumfilelist can give you a list of forms or libraries, then scan that list with enumsource and build a table of your code an "org chart" of what calls what can be simple or complicated, depending on the complexities (or lack therof) of your app

Paradox & Custom ODBC Driver
Does Paradox support connecting to 3rd party or custom ODBC data sources? I have one installed, see it in the BDE Administrator, but can't find where I can connect to it from within Paradox.

Thanks for the quick responses.  The link to the BDE helped me get the ODBC driver setup and I can now see it in Paradox. Thanks!

Unknown internal operating system error
I cut and paste images into an image field on a Paradox form and I've been doing this with no problems for years; yesterday I got a message saying 'Unknown internal operating system error' with a reference to the .MB file, when I tried to paste an image in. Paradox hung. After restarting, I verified and rebuilt the table and it imported the image ok but when I tried to do it with a new record the same thing happened. I'm using Paradox running on a Lenovo laptop with Vista Home Premium and Service Pack 2. The database has 121,900 records in it but not all of them have images. Does anyone know what might be causing this? Any help would be appreciated, thanks.,

Thanks!  I've used ChimneySweep before (probably have a license for it!), but I'd forgotten about it.  Thanks for the heads-up/reminder!  I'll check it out.  (As I recall, it was very useful in fixing things that the built-in "fixer" couldn't fix.  I'll try to dig it up & see what it can do with these memo fields!) Thanks again! Aloha, -pt
