here is from cheatcc.com thats where i get all of my cheats:
# Testing cheats mode
While playing the game, press [Ctrl] + [Shift] + C to display the console window. Enter "boolProp TestingCheatsEnabled true" to activate testing cheats mode. This is a very powerful cheat that enables many new things. In Create A Sim, after enabling this code, go into debugmode by pressing [Shift] + N before making a Sim. You now have the following new things in Create A Sim: skin tones, clothing, and some other options such as viewing the skinfilenames. In the game itself, after enabling this code, hold [Shift] and left click on a Sim to have lots of options, such as changing clothes, make your Sim fat or thin, set their aspiration level, etc. This code also can spawn some interesting items, such as the tombstone of L(ife) and D(eath), and family members.
Enable the "boolProp testingCheatsEnabled true" code, then go onto a different family. A strange code will appear at the top right hand corner. If you go onto the Sims' needs, you can click on each one and drag it up or down, whichever desired. You can also increase the skill points of your Sims in the same way. This is useful if you want a promotion, if your Sim is depressed, if you are teaching a toddler to walk, etc. You can also hold [Shift] and click on a Sim. Click on "More", then "Spawn" and create the Tombstone of L and D. You can click on this, then "More" then "Make everyone here friends with me", which helps if you need friends to get promoted, or to complete an aspiration task.
# Maximum skills
To fill your skills to the maximum level instantly, enable the "boolProp TestingCheatsEnabled true" code. Then, pause the game without going into build or buy, and select your skills icon. When you are in the tab with the skill meter click and drag the pointer over the desired skill bar to raise it.
# Gain skill without losing money
Use the following trick if you do not have a lot of money and want to buy goods or an object to gain more skill to get a promotion. Buy the particular goods that will help you for a promotion (for example, an exercise machine, or book shelf) and study the knowledge (for example, cleaning). When you get a skill point, delete the item that you bought (sell it before 24 hours have elapsed). You will a get full refund back from that object. If you sell after 24 hours, you will get less money. By doing this, you will gain your skill without losing your money.
# Buy expensive houses
Use the following trick if you want your average Sim to buy a house that is above his or her means. First start a family or load one, and find an empty lot. Move the Sim on that lot. Enable the "motherlode" code a few times, just to the point where you can buy the expensive house. Exit the lot, but save the game. Then, evict (move out) the family. Notice that your family is displayed at the "Choose Family" window. You can now buy any house desired.
# Quick money
Get a friendship with a rich Sim (girl recommended). Ask them to to move in. The Sim will bring at least 20,000 Simoleons with them. The money will be added in your account. Then, you can make him or her move out.
# No job
When you first move into your new house (especially if you have any kids or plan to, or if you have the Popularity, Knowledge, Family, or Romance Aspiration), do not get a job. If your Sim has a Family Aspiration, then keep it at home to potty train, teach to work, or talk your toddler. If you have Romance, you must keep up with them woohoos. Knowledge may require you to get a job, but it probably will not be a power want. Popularity aspirations will keep you home making friends (unless they work); stay at home and take care of your Sim, their family, and their aspirations.
# Never pay bills
Go to buy or build mode and use the hand tool. Pick up the mailbox and delete it.
# Free groceries
Order for groceries and wait for the man to deliver the goods. When he arrives, do not greet him. He will ring the bell two or three times and wait for you. When you do not answer, he will place the goods there and not take your money.
# Select a baby
Go into buy mode. Enable the "moveObjects on" code and click on the baby you wish to select. Without deselecting the baby, use the "moveObjects off" code. Still without deselecting baby, press [F1] to enter live mode. You will now be able to view the babies needs. The baby can only perform one interaction. Click on it, and for a moment a menu will appear that says "Grow Up". If you want an alien child or any child that looks like your family when you adopt them, go to the certain family, and delete the entire the family except for the baby by using the "moveObjects on" code . The social worker will arrive and take the baby. Go back to your other family and adopt a baby. You will get the same child that got taken away.
# Build toddler skill four times as fast
Wear a Thinking Cap and feed Smart Milk to your toddler.
# Custom paintwork
Use the following trick to decorate your house with custom art. Your Sim must have a Creativity level of 5 and be able to paint a still life. Have your Sim paint, and a frame will appear. Center it on what you want to paint. You can also "paint" something that is not in the game by pressing C to pause the game, then press [Alt] + [Tab] to switch outside the game. Start a graphics program, such as Windows Paint, then load the original captured in-game picture at "c:\mydocuments\eagames\thesims2\storytelling\snapshot.bmp". Then, open the picture or image that you want to replace it with, and put in your game. You must resize your custom picture to match the same resolution as the "snapshot.bmp" file. Copy your custom picture on to the "snapshot.bmp" file, then save it. Press [Alt] + [Tab] to switch back to the game. Your Sim will begin painting your custom picture.
# Custom radio music
Copy your own MP3 files to the "c:\mydocuments\eagames\thesims2\music\[radio station]\" folder. Start the game, go to the options menu, select the music settings, then the radio station option. You can now choose which songs you want to hear.
# Custom television show
Copy your own AVI files to the "c:\mydocuments\eagames\thesims2\music\[television station]\" folder. Note: The AVI file must have a 128x128 resolution and a frame rate less than or equal to 15 fps.
# Listen to game's audio
You can play a lot of the game's music and sound effects as MP3 files on your system. Enter the "\tsdata\res\sound" folder. Then, copy any .PACKAGE file to some other location. Rename the copy so that it has a .MP3 extension. The resulting file will be playable as a normal MP3 file. If you want to get a specific track from within one of the larger files (such as the stereo music) you will need a program capable of editing MP3 files.
# Invisible Sim
Enable the "StretchSkeleton" code and use the following value: 100000000000000000000000000000000000.0. Note: This will affect how tall the Sims will be. 1.0 is normal. Your Sim will be so tall that they cannot be seen. Exiting out of the game will deactivate the code.
# Social worker does not leave
When you adopt a child, if you greet the social worker before she rings the doorbell, the social worker will not leave your house. If this happens, you cannot buy items, build, or save the game.
# Floating house
Place a lot of columns around the ground and build your house on top of it. When you are done, delete all the columns. Note: Make sure you have a way to get to the house, or no one can get in. Also, you can build a house up to ten stories high up. Make sure you put floor tiling on the top of the column so you can put another column on top of it.
# Death and ghost types
Old Age: When a Sim reaches the end of his life. Results in a white ghost.
Electrocution: Three or more Needs hit -90 (red) while a Sim repairs an electrical object with a low Mechanical Skill. Results in a yellow ghost.
Burning: Fire spreads into the square where the Sim is standing. Results in a red ghost.
Drowning: Energy Need hits -100 (all red) while swimming. Results in a blue ghost that leaves puddles around the house when it appears.
Starvation: Hunger reaches -100. Kids and younger cannot starve. Results in a transparent ghost that will take food out of the refrigerator.
Disease: If a fatal disease is not treated for ten days the Sim will die. Results in a green ghost.
Flies: In a very messy room, when a Sim steps over a plate all flies may form a deadly killer swarm. Results in a purple ghost.
Scared: When three Needs drop below -90 because of a ghost scare. Results in a pink ghost.
Satellite: When a satellite falls on a Sim while Stargazing (without a telescope) or Watch Cloud. Results in an orange ghost. Note: You can sell the Satellite in buy mode.
Note: Babies and toddlers are fire-proof and cannot die by any cause; the Social Worker will instead take them away. Children can die of fire, drowning or disease. Rather than starving to death, children in hunger failure will be taken away by the Social Worker.
