Module development and code questions

Dear Forum,

I am very new to drupal module development. And I have what is probably a simple question but I can't find the answer to it!

I am creating a module and I need a url to be called after the submit button is pressed when a node (story or page for example) are updated.

Would anyone be able to point me in the right direction?

Thank you

David

Hi friends,

I am developing secure section for our staff. I am looking for a module which can provide functionality:

1. Edit content online
2. Members can see the changes done by other members
3. Function to rewind the changes
4. Authorize person can finalize the document and after that other member cannot make any change.

I am expected something like wiki. Is it possible?

Please tell me which module should I use.

I am developing a module for tracking stock portfolios and I am having trouble understanding how to use the forms API to achieve what I want.

When I create a portfolio I want to present a form with the entry fields in a table. The table has a header and five rows to collect the stock symbol, number, price etc.
At the base of the table I want a submit to add five more rows (if required) and a submit to process and save the portfolio.

Drupal has been working great for me so far but have one issue.
Emoticons with the smileys module won't show up. I've been checking the forums but nothing has been able to help me. The thing is, it works, but only if I use my (admin) input format, if I use the filtered HTML nothing shows up at all.

The only difference that I can think of between these to formats is that the filtered HTML doesn't allow img-tags. I want to keep it that way.

Any suggestions?

hello,
I want to have a feature that would allow the users to invite their friends from their Gmail, Hotmail, AOL, Yahoo and imprtantly - Outlook.

is there a module that does this?

I 'm having trouble with assigning a directory to different pagetypes with the cck filefield module (the image_field module on the contrary works fine). Also the upload path module does not seem to support teh cck filefield module.
So I was wondering what would be the best way to go: develop my own file upload form field or use a solution which is out there somewhere.
