I am using the ipconfig command line utility to view my current TCP/IP configuration. I understand that ipconfig when used with the option
/release – releases my DHCP configuration
/renew – remews my DHCP configuration
/flushdns – Purges my local DNS cache.

I have done this to get my Internet problem sorted most of the times. But, I recently came across my School System Administrator using these two options on the ipconfig command:
/setclassid and
/registerdns

Can anyone explain me what are they used for? Also, is it equivalent to putting an entry in etc/hosts file?

I am looking forward to start developing iPad applications on my Windows machine but I have hardly had any luck succeeding in it. I even went through the plenty of iPad related forums and came down to this list of two such SDKs:

1. Dragon Fire SDK
2. RhoHub

However, I am still not sure which one to go with. Can anyone please suggest?

PS: Please do not reply saying why not buy a Mac as that is not in my budget for now.

Hoping to get some good experienced based responses from the experts.

I have search all over just to add a simple field or form to a template, that I can reuse in the documents I create.

What I really want is a place-holder text called "Purchaser Name", and another called "Client Name", so that in a new document I could just click anywhere on "Purchaser Name" and "Client Name" (NOT select and type), fill in the names, and in the rest of the document where I placed the "Purchaser Name" and "Client Name" would automatically update/fill in.
