The moment you use standard Transact SQL, a rouge code is inserted unknowingly into your query. The hackers then use the queries to change tables, get information and delete data. To prevent this, you should always use parameterized queries.
While displaying error messages, don't disclose much. For instance, if a user 'usereone' enters wrong login credentials in login form, don't publish the error message like this - 'usereone' enters incorrect user id and password. You should think about the language while communicating the error message. The error message could lead to brute force attack, where hacker does know your user name ('usereone') and all that he needs to manipulate is your password.
Server Side Validations:
To make your website hacking proof, perform validation both on the browser and server side. Validations should be triggered if a user attempts to enter strings into a numeric-only field. You should implement these validation and deeper validation server side as well. Failing to do so could lead to malicious code or scripting code being inserted, that could cause undesirable results in your website.

If your website has a form uploader, you need to be extra cautious. If users are allowed to upload images, you can't rely on the file extension or the mime type. There are cases when opening the file and reading the header, or using functions to check the image size are not full proof.
