Module development and code questions

has anyone been able to get shapefiles to work with gmap api within drupal?

I've been poking at the ideas of a Drupal webmail interface about, and haven't seen too much activity on it. Namely:

• Pontomail
• rcmail

Pontomail hasn't been updated for 5.x, so I haven't given it a try yet. Roundcube is functional, though I'm not overly fond of the (albeit, seemingly necessary) iframed node approach.

I'm writing a search tool . These are the requirements :
- Users can search by ID or Name.
- If Users search second ID, the information of 2nd ID will be displayed in new tag. This tag is always changed ,and just only show the previous ID searched.
Thanks for your supporting. Please giving me a simple example if you can,which makes everything clear when we have a simple example to show that.

So there is quite a few problems when combining the Acidfree with the Category module.
Has anyone managed to get the 2 working together?!?
If not ... anyone want to work on it with me? I started a bit, but got bogged down by the complexity and extreme lack of docs/comments.
Any help would be good.

Hey all,
Somebody built me a very small, but custom module a while back and there is really have very little to it and mostly is just made from what I added with php/mysql. I don't know anything about the actual creating of modules and I am just updating my site to 5.0. The problem is the module no longer shows up under the Administrative Modules area of my site so I have no Enable it or give Access to it.

I can only guess that there is probably just a simple line or two to change, but I have no idea what it is.

I am using Authorize.net as a gateway payment.

The transaction type (x_type) is hard code to AUTH_CAPTURE which means that all transactions will be settled upon submission. I can change this setting to AUTH_ONLY which allows for charging at an ulterior time.
