Convert .dat database into .mdb

In VB5, how can i access any database(.dat), read every record, then convert it to Recordset, & save as (.mdb) database ?

NB: The (.dat) database & its fields are specified by the user in run-time, thus, how can i use VB5 to detect the dbase fields, & subsequently create them in (.mdb) ?

Looking forward to ur reply,

Sounds to me like you already know exactly what to do:

1.  Create a ODBC connection to the Databases files as provided by the company.
2.  Create an msAccess that would link to the tables in the database.
3.  Create another msaccess database which will contain the fields you require.
4.  Write your program so that it reads the information from the source table and puts it into the destination table.  I would make the source table open a snapshot so it is read-only...Better performance and less chance of writing to wrong table.

What database is (.dat) file?

(.dat) which i encounter is a SCALA4.0 databases. Assume it is a normal databases (eg. .dbf, or .txt), is it possible to detect/capture the fields & widths of a database in VB5.0 ?

there is a MSDN article which shows how to convert a ASCII text file in to Access Database from scratch. the URL is :

let me know if this helps,

Do u know whether VB5.0 can read binary file in RecordSet ? Or i need to open it using Seq & Random access method for Binary .dat file ??

.dat file is a SQL server datbase database file is it?
What system or program makes the .dat file you wish to read?

Its easy to read files using binary file i/o in vb:
buf$=space$(50)  'input record buffer for record len=50
open "MyFile" for binary as #1
while not eof(1)
 get #1,,buf$
 'do something with the stuff here, like
  'make an insert statement "Insert into tblnam(fld1,fld2..)
  'and use .execute on the connection object to insert data
close #1

Or you can create a type structure to read the records into and break down into fields via the type udf.
I see two parts to your question.  The first is that you need to be able to read the .Dat File; and the second is being able to import the field information to an mdb file.  Reading through the comments I get the feeling that more information is needed about your database source.  I did a search on the web for SCALA and found a Business Administration Systems.  This system has a statistics module that allows you to export information so that it can be used in spreadsheets and so on.  Is this what you are doing?

sdbanks, & all,

your rephrasing of my question is Right. Thanks.
(i)to read the .dat Scala data file, my recent soln is to use Scala's provided odbc driver (pervasive odbc) and access a .dat in a network drive. (Qn) However, is there a way to read the .dat file in my local harddisk c:\ ??

(FYI, true enough i can export a statistics module to xls, but i/we are now trying to read/export other modules like general-ledger, sales-ledger, and all rest, inorder to consolidate with same modules in other geographic location.Scala does not provide export of other modules, although it can read/display them.)
(ii) to export to mdb database from .dat
tentatively, i would use MS Access(mdb) to link to Scala .dat files, using (pervasive) odbc drivers, and VBasic will open Access(mdb) and access them.
Is it advisible to use DAO recordset in VBasic to access Scala .dat files, using odbc ? without going through MS Access ?
