but i want to change the ip of the mysql database ex instead of 127.0.0.1 a want to connect to a remote pc where mysql is intalled...
i tried this but

  Dim Logoninfo As New TableLogOnInfo()
        Logoninfo.ConnectionInfo.ServerName = "127.0.0.1"
        Logoninfo.ConnectionInfo.DatabaseName = "db"
        Logoninfo.ConnectionInfo.UserID = "root"
        Logoninfo.ConnectionInfo.Password = "test"

        cryRpt.Database.Tables().Item(0).ApplyLogOnInfo(Logoninfo)

        cryRpt.VerifyDatabase()

i always get logon failed although everything is correct(i use it with 127.0.0.1) moreover i want to use recordselectionformula but again no luck
