first thing i can think of is, if you are using Delphi 5+ then use the ADO components, then you can write the ConnectionString at run time. If you want to use the BDE (in any delphi), then you can use a TDAtabase at run time too. Beware of using the BDE driver for Access 95 to open an Access 97 database.
So, what Delphi are you using, what Access version, and do you want to use the BDE (I hope not)?

If you have the ADO components, drop a TADOConection on your form and double-click on it. Then click 'Build'. Select 'Microsoft Jet 4.0 OLE DB Provider', 'Next' and type/browser the .mdb file (path can be relative or absolute). Now 'Test Connection' to see if it works.

After that you may want to set TADOConnection.LoginPrompt to false.

Well... Use ADOExpress components (ADO tab).

1. Place ADOConnection component onto your form
2. Doubleclick on it to open ConnectionString editor
3. Press Build button
4. Choose Microsoft Jet OLE DB Provider and press Next
5. Select Access database file
6. Specify Password if needed
7. Press Test Connection button and if connection succeed press OK
8. Place ADOTable component and set its Connection property to previously placed ADOConnection component
9. Specify TableName property
10. Place DataSource component from Data Access tab and set it DataSet property to previously added ADOTable component
11. Place DBGrid component and specify its DataSource property
12. Set Active property of ADOTable component to True.

Best regards,
Alexey Zverev.

...unless creating an alias at runtime is an option:

Yep as Epsylon has said if you don't use ADO then you will need to use alias's in one form or another.

No comment has been added lately, so it's time to clean up this TA.
I will leave a recommendation in the Cleanup topic area that this question is:

Accept karouri's comment as answer (TDatabase at runtime)

From Delphi Help:
AliasName and DriverName are mutually exclusive BDE-specific properties. AliasName specifies the name of an existing BDE alias to use for the database component. The alias appears in subsequent drop-down lists for dataset components so that you can link them to a particular database component. If you specify AliasName for a database component, any value already assigned to DriverName is cleared because a driver name is always part of a BDE alias.

Note: An application can specify the DatabaseName, DriverName, and Params properties rather than setting AliasName if the desired BDE alias configuration does not already exist. An application can also provide an application-specific “alias” name by setting DatabaseName when AliasName is already set.

Please leave any comments here within the next seven days.
Thank you,
