Perhaps a better idea would be to bind your DataReport to a query that has SELECT TOP 200 in it.

As for securing it, you can check out the links that myself and Computron posted here

regarding setting the database password / userpassword on the fly.

Dear Jimhorn and Dear Leclairm,
First of all I hope that you accept my apology for being that late to reply to appreciated answers since i was away
and busy somewhere abroad...

regarding my question...about making a query I thought this may take a big file size on the user HD each time to create
a query...Besides I really do not know how to do this if it is a practicle thing...

I want to avoid securing my mdb by a password... Iam doing this program without having learnt any course in programming it is as a hobbey so do not bother by stupid answer if I tell you I could not follow the link you gave...

folk I do not want to be rude but if I do not hear from you the next 2 hours I will split the points
and again I do apologise for the whole issue... thanx in advance.
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Jim HornMicrosoft SQL Server Data DudeCommented:
A query is basically text that specifies what tables/fields you are using.
For example, if your existing data source points to a table that has 10,000 records, you are loading 10,000 records.
By creating a query that only returns the TOP 200 records of that table, then using it as your data source, you are loading 200 records, which will be much faster and take less memory.

Also, if you want the easiest way to password protect your mdb,

open the database in exclusive mode (file/open, then choose open exclusive on the "open" combo box)

go to tools/security/set database password.

This will prompt you to type and retype a password that will be required each time you open it.

Cheers,

Mike

In visual basic, you can then pass this password in your connection string:

dim conn as new adodb.connection
conn.open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Yourdb.mdb;Jet OLEDB:Database Password=YourPassword;"

I hope this helps.
