Hi,
looking the past posts I learned how I can create a new linked-table in
an existing MS Access database, using ADO components and SQL commands.
Now I'm trying to understand how I can create a new MS Access database,
so could you please explaine better the source code you post?

In strConnectionString I put yhe following:
"Provider=Microsoft.Jet.OLEDB.4.0;Data
Dource=db.mdb;Mode=ReadWrite|Share Deny None";
but BCB6 give me a memory error when I run the program, even if it
create the MS Access database.
What's the meaning of
> CoInitializeEx(NULL, COINIT_MULTITHREADED);
because I don't found anything about it in the BCB6 guide.
Thanks for the answer.
Pat
