Create a field definition file from VBA

I think what you refer to as a field definition file is what MS refers to as a Schema.ini file for Microsoft Access.    
                 to make a schema.ini file from a db table

                 to read a text file into a recordset using a schema.ini file

Hope this helps.

Here is a good tutorial on exporting Access schema using XML:
                     http://articles.techrepublic.com.com/5100-6329_11-5035228.html

Your first link refers to schema.ini which is not what I need.  I need an XSD file.  Your second link provides this, but it's for use with Tables, Queries, etc...  I need to export an ADO recordset to an XSD file so this still will not work.  I have found a utility called xsd.exe which creates an XSD file from an XML file (which I can create from an ADO recordset), but this XSD file cannot be used in Crystal Reports - it tells me the file is not well formed.  

Moreover, I am going to have to do hundreds of these.  I'd think there was an easier way to connect Crystal Reports to an ADO recordset created in VBA code, but it seems they have nothing that works in this fashion which essentially makes CR useless for an Access or VB Application (unless the developer is using very simple techniques).  This is why I know something must exist, but nobody seems to know what it is.

You might want to consider a commericial converter like this:
                     http://www.milestone.ca/access2crystal.asp?rmnu=Product&RetailSoftwareid=7#
                        free demo version allows you to convert 5 reports  ( costs $295 to buy full version)

That's almost exactly what I needed.  Thanks!  Access converters never work well, plus we don't have the original Access reports to convert (we're building this application from scratch based on the process flow of an existing aplpication).

Glad I could help.  

CyprexxDev,
Earlier tonight I happened to see your second post, but when I went back to try and read your request in detail, the post had been deleted.  Did you get what you needed from my answer above, or do you  need a different code set?

I figured out where to get the p2smon.dll file so I could create the TTX file from within my VBA code (based on an ADO recordset).  This pretty much has solved my problem.  I can get everything to work as needed now.  I'm sure I'll still have more questions as I go along though :-)  Thanks for all your help.
