Hi guys! I'm a total noob when it comes to this. I have searched online and found a number of articles/guides about strings and substrings and I get the concept of it but I don't know if this is the correct way of implementing this. I've also seen that a number of people don't suggest saving multiple checkboxes into one field in the table. However, in this instance it would be necessary.

This is basically for a user access menu and additional options. As you can imagine, there are many checkboxes so it's not feasible to create individual columns in the table for each checkbox.

This is for Winforms and C#

One set of checkboxes are all saved to the AccountUser table, AccessTable field.

Any guidance with code to save and retrieve the checkboxes would be appreciated!

I haven't tried anything as of yet as I don't know how to best approach this. Any guidance would be appreciated.

This is wrong approach!

Imagine, you've got 4 menu items: {A, B, C D}.
There are 2 users in AccountUser table: {1, 2}, who can access menu items as follow:
[1] - {A, B, D}
[2] - {B, C, D}

So, you have to define another table to store menu items, which every user can access (User_Menu table):

UserId    MenuId
1         A
1         B
1         D
2         B
2         C
2         D

To get menu related to user #1:

SQL

SELECT MenuId
FROM User_Menu
WHERE UserId = 1;

Finally, i'd suggest to read about authentication and authorization.
