The 3DS does not have a video-out port, so the only options are,
1 - Get your hands on a reviewer machine. Large, trusted review sites are sent special machines that do have video out, so the reviewers can take screenshots of the games.
2 - Purchase an expensive capture card and install it inside the 3DS, allowing visual data to be captured by a PC.
Yes. But most PCs do not have a DVI output, so you will need to purchase an adapter.
There is no easy way to do this. The 3DS does not have a video-out port, so there is no way to connect 3DS to a TV to display its video on the screen. Instead, you need a capture card, and this card must be installed inside the 3DS, spliced into the circuitry, with a hole cut in the case for its USB port. This port can then be connected to a monitor to stream the 3DS's video data.
You will need a TV tuner card.
My 3DS cannot connect to my router. The router was reset and, of course, it wouldn't let me connect. So I deleted the settings and set it up again. The WEP key was correct and so was the SSID, but still I couldn't connect to the router. Can somebody help?
yes, the wii and the 3ds have a similar home menu and settings mechanic so yes.
There are no working 3DS emulators at the moment.

Not in the sense that you can communicate peer-to-peer, but you can use a computer with a wireless NIC (read: wireless card or wireless capabilities) to run as a wireless access point (read: wireles router).
so u can see what you typed on the computer
Depending on what you have done you should just be able to plug it in, it will ask you on i Tunes if you would like to sync or erase and sync. So you should be able to. Same if it was synced with a different computer.
Anything the laptop can send data too that is presented to the end-user is technically an output device. The built-in display, a monitor you connect through one of the data ports, a printer, etc. So yes, a monitor is an output device for a laptop
I believe that it is possible to connect to computers to one monitor. I have worked with brand new LCD monitors with two inputs - one DVI and one VGA. The monitor auto-senses which port is being used. So in theory, use the auto detect button on the front of the LCD panel to switch between computers.
