problem with connection strin in ado.net

[maged]

hi all, i am trying to connect to an access database, it has a password called : "xxx" , i am using a connection string as following but it keeps pop up an oledb exception.

when i use the same connection string on a database without a password, i have no problem

here is the problemetic connection string

db.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:\mainx.mdb;password=maged;username=admin"

thx in advance
