Just to confirm, you added the SDT classes from the \Stonefield\SDT\Source folder to your project? Just make sure they are either included, or provided if excluded. The following is what I have in my apps:

oMeta = NewObject("DBCXMgr", "DBCXMgr.VCX")
if vartype(oMeta) <> "O" or IsNull(oMeta)
return .f.
endif
if !oMeta.oSDTMgr.OpenData(DATABASE_NAME, .t., .f.)
return .f.
endif
return .t.

>Mark, thanks for the suggestion. I have eliminated the duplicate lMeta reference and the code is now as follows, yet when I do the transfer to the second computer and try to run the application, it tells me the 'Database is invalid'.
>
>I changed the 4th property to .T. (to run in debug mode) and it tells me that 'DBCXMGR.VCX' does not exist. As per the manual, both DBCXMGR & SDT are added to the project.

>Any other suggestions for me to look at here?
