I'm writing a program that uses net framework 4. another person will use this program in his own computer. Is it necessary for he/she to have net framework 4 installed in his/her computer? which version he/she will require?

I don't use class in this manner. I mean grade for classes such class A is for student of 7 years old and class B is for student in age 8. student table has class_id field too. in this way one student can have every book of class like, math, english,... and each book belong to all student in class. so I create studentbook table which has book and student ID and an extra field: RESULT. well student table will be fill by a user of software. afther a long time he/she will import student result which goes in studentbook table. question is how and when studentbook.st_id and studentbook.book_id should give value. suggest a query and when use the query, when importing the students or when want to import results?! As you know it's my first database as homework. :wtf:

1. I use vs2010. I want to add a "LOCALE" database to my project. just local not in localserver. connecting vi binding a datagridview works. but connecting vi ado classes (sqlconnection) not work cause wrong connection string. I test many connectionstring even orginal connectionstring that binding use "4 ex: datasource:|datadirectory|\text.sdf" but wrong connection string error occur. in vs 2008 I had no problem. 2) what kind of database is better to use in simple program: local? or in localhost? after publishig the program will use in another pc. is putting db in localhost is work then?

I have simple db with 4 tables: class, book, student and studentbook. studentbook has st_id and book_id as foreign keys and an extra field for result. book has some book for classes. I just insert new students. I'm quite beginner in db and don't know how to fill studentbook. should I fill it (just foreign keys) when filling student table? or it can be automatically? I don't know the routine. I should insert students and result in different times. Extra information: I use visual studio 2010 for programming and access 2003 for db. for user-friendly reason I want a datagridview that shows students and result in on table to insert result for each student. I got some success but it's not quite update but inserting action, that my insert two or more rows for a student in studentbook table cause clicking of updating button. Please any idea or simple code?
