I've got 3 questions.

1. Who has had what kind of problems with the ADO Data Control after installation of Access and SP4?

2. Does anyone know how to detect the format of a database through means of something besides the reliance on file extensions?

3. Does anyone know how to change the SQL of a command in a Data Environment to filter a report(using MS's new report designer) based on user selection?

Answers to/help with the second two questions would be greatly appreciated.

Thanks,
David
