okay so i have Form2 which has a db table named Car using LINQ with four attributes(Make, Model, Year, Price). Now Form1 has 4 textboxs using ReadLines to acquire the make,model,year,price). How do i get them to insert into the table on Form2. thanks in advance for the help.

Please post your code so we can help you figure out.

THIS IS FORM1, im sure it needs revision. i based my code so far on console applications. im not too familiar with windows forms
