Using Access 2007 I am trying to create a csv file on my hard drive via an automated export.

The command line is:
DoCmd.TransferText acExportDelim, "product_master Export Specification", "5000-0 product_master", "L:\Ross ERP\FileUploads\Automated\product_master", True

I get the error "Cannot update. Database or object is read-only."

I definitely have permission to write to the drive

Can anyone tell me what I have done wrong

I read this in Helen Feddma's "Access Watch" newlsetter. Whilst I have some code that does work, I don't tend to export files in any 2007 systems (yet)

Q&A
Changes in Import/Export specifications in Access 2007
Q:  Fred Kerr writes that code for importing data from text files that worked fine in Access 2003 doesn't work in Access 2007.  Why?

A:  If you are using a saved Import spec, it won't work in Access 2007.  There was a significant change in Importing/Exporting in Access 2007; import/export specs are now saved in a system table, and are not available for use in code.  You can create and save specs in Access 2007, but they can't be used in code, only in the interface (why Microsoft did this is beyond me!).  Here is what I say in my Chapter 10 of my new book:

Unfortunately, Access 2007 VBA code doesnt recognize saved specifications. This feature worked for several previous versions, but at present it is broken, so we must wait for a patch or service pack to fix it. For now, only code that avoids using specifications will work.  (You can import from, or export to, a comma-delimited file without a specification, but not a fixedwidth file.)

However, you there are several other options for working with text files; you may be able to use components of the FileSystemObject, ADO code or legacy VB statements for importing data from (or exporting data to) text files.  These topics are covered in Chapter 9 of my new book, Access" 2007 VBA Bible For Data-Centric Microsoft Applications.

Doesn't sound very promising to me.  Damn

Do you have any idea how I can export to a comma-delimited file without a specification?

Firstly I check my using the manual export functionality from the ribbon bar to ensure all works that way and that there's not another problem, then try the export leaving the specification blank (I think it's optional). You'll end up with the deafult settings for days, fields etc.

I don't see this fix in the list of fixes for SP 1.

Did you leave the spec out of the VBA version

i.e.
DoCmd.TransferText acExportDelim, ,"5000-0 product_master", "L:\Ross ERP\FileUploads\Automated\product_master", True

The amended command is:

DoCmd.TransferText acExportDelim, , "5000-0 product_master", "L:\Ross ERP\FileUploads\Automated\product_master", True

Still same error.

Try creating a macro for the export (is based on the ribbon bar version). Seems like 2007 is heading back down the macro path.

There just doesn't seem to be any way of creating a csv (or at least the definition)

Seemed to run at least .... but looked like a report

Any ideas

This is using the "OutputTo" macro command

There isn't the equivalent of "ExportTo"

You can create a "saved Export" to a text file which seems to be the new "specification". You just need a way to run that from code or a macro. I'm a bit tied up to follow that further at the moment.

This seems to work:

DoCmd.TransferText acExportDelim, ,"5000-0 product_master", "L:\Ross ERP\FileUploads\Automated\product_master.csv", True

I added the csv bit
