To Whom It May Concern. I have tried to use Perl DBI and MS Access together for 2 weeks. But even though I programmed the same code as the code is shown above, it keep telling error message: CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are: DBI->connect(driver={Microsoft Access Driver (*.mdb)};DBQ=2000ticket) failed: MicrosoftODBC Driver Manager Invalid string or buffer length (SQL-S1090)(DBD: db_login/SQLConnect err=-1) at d:\inetpub\scripts\find_ticket_test.pl line 19 I really do not know what to do. Please answer my question. thank you
