Database connection

no, we don't help thread hijackers who are too lazy to even read the tutorials (if you'd done that you'd have figured it out for yourself).

m not lazy, i learned tutorials nd do alots of surfing,, but they dont solve my problem, that y i post here,,,

So why didn't you post your code with an issue you facing instead of boasting what everything you did. We do not see code we cannot help and mind reading is different ocupation...

m not boasting,,,

i had done tockeninzing of my data in the above code, nd wants to store in database, but failing to store in database.

don't make your code more complicated try out some simple coding like the code given below to store the values into database.

This is a login example which the user will fill the information n the values will get stored in the database named Login.
As you are new to this stuff try to make simple first and then try out some complicated ones.ok

i have to read form a file

so? What's stopping you? Too lazy to figure out how to do it yourself?
