Drupal 7.x

Hi, I am new to drupal and I am searching for functionality specific to comment access. I have 3 content types - Projects, Assets and Information. I want certain users roles to be able to comment on/view comments for certain content type. So only faculty(user role) should be able to view/give comments on Assets(content type). Students(user role) should be able to view/give comments on Projects(content type). Is there a module which can do this ? Can I achieve this using Rules module ?

Hoi,
Can somebody help me ? i don't know how to do it !
I would like to make a little application where you can upload some video's or images, so each time the user can call this application to upload a video or image at anytime. the application need to include some combobox, fields and of cours the unique ID to linked to the user.

How do you call this module ?

How to generate a new image based on text fields and picture fields?
I have a content type. In the content type are text fields and image field. I want to show for visitors new image. The new image is a composition consisting of text and image.
How to do this?

I have a MySQL table like this:

CREATE TABLE `rooster` (
  `datum` date NOT NULL default '0000-00-00',
  `tijd` varchar(15) NOT NULL default '00:00:00',
  `wat` varchar(30) NOT NULL default '',
  `data` varchar(128) NOT NULL default '',
  PRIMARY KEY  (`datum`,`tijd`,`wat`))

I want to create a view (=drupal view) with this table, but Drupal complains about the date....

Hey All

I am developing a site where authenticated users shall fill out a complicated form.
All data should be recalled in the form and saved in the database.
What is the best way to do this? Make a form using the form API and make a custom table in db or make a new content-type with a lot of fields, and let drupal do the database work.

cheers

As title, my module is called testmod
In file testmod.admin.inc

module_load_include('inc', 'testmod', 'arrays');
......
function testmod_admin_settings_submit($form, $form_state) {
global $array1;
global $array2;
if (in_array($form_state['values']['license_id'], $array1) == TRUE && in_array($form_state['values']['license_key'], $array2) == TRUE) {
drupal_set_message(t('Success!'), 'status');
} else {
drupal_set_message(t('Failed!'), 'error');
}
}
