Drupal 7 - Module with form and view
I have never used it in that way, but some thoughts:

The second link doesn't seem relevant, as I suppose that you use Views 3.

If you use the approach described in the first link, than you don't need to implement hook_form() in your module, instead you need to create a views field handler and there you need to define the methods views_form()and views_form_submit(), optionally also views_form_validate(). You would then "add the form to the view" using the Views UI where you can add the field (the one that you have written a handler for) to the display. That's  how your handler get's called and is responsible for the rendering of the element, which usually renders a value wrapped in some markup, but in your case it would render a form.

The first link explains that all very well. Just go through it again and try to follow it in detail.
