3DP Net is an extremely useful utility that allows you to determine the model and install the appropriate driver for the network card installed on your computer. In fact, we have before us a separate tool from a comprehensive program for updating and installing missing drivers called. It is easy to guess why the developers decided to "isolate" a separate application from this complex. The fact is that without a driver for a network card, you will not be able to connect to the network and, as a result, update other drivers using.
The main advantage of 3DP Net is that the program (which, in general, is logical) does not require an Internet connection, and all the necessary drivers are already "bundled" with the program. The user only needs to launch the application, wait until it determines the model of the network card and selects the appropriate software for it from its "library". 3DP Net works equally effectively with both "stationary" computers and laptops. It is completely free, does not require installation, and is even translated into Russian. In general, we have an extremely useful tool that can come in handy at any time.
Key features and functions
- knows how to determine the network card model and install software for it;
- is part of the 3DP Chip software package;
- can create backup copies of already installed drivers;
- does not require a network connection;
- almost completely automated and distributed completely free of charge.

They say that the birthday
This is a holiday for one.
We do not agree with this.
We need to congratulate three.
Mom, who does not sleep at night,
What shakes until the morning.
Papa, who is holding the hand,
that plays endlessly.
And, of course, your child
He's three today!
No matter how many words we say
You alone will understand them.
That your child grew up in the world,
He was bright, smart and brave.
So that he is not forgotten
Happiness, joyful lot.
So that he grows to your joy,
To be proud of them
To remove obstacles from the path.
And may God bless!
Yes, three years have passed
Your child has grown up.
Learned to speak
Run, jump and walk!
Dance, know how to joke,
With strangers no longer shy,
Sings wonderful songs
Praise awaits for this.
Happy birthday to your little one!
Let him eat excellent porridge,
Smiling more often
Well, let life be sweeter!
So your baby is 3 years old. May his childhood be the best and brightest. It grows without problems and hassle. Let him be in an island of warmth and joy. I wish him to grow in abundance, healthy and in love.
How quickly the days go by...
You're exactly three today
And it seems like yesterday
The first words were spoken.
To the joy of loved ones you grow,
Bring them love and happiness.
Let childhood give miracles.
May the heavens guard!
From Mom
With you we are inseparable
I know you inside and out.
Forty weeks were one
We've been one for three years now.
You are the long-awaited meaning of life,
You are my light and joy
You are my fragrant flower.
I live keeping that tag.
My precious angel
Grow big for my joy!
I love you, my dear,
You are the best on earth!
Three years is the date
Whatever you say!
Once upon a time I was small
Well, now look:
And jumping and jumping -
You can't look after him!
Of course, this means
How your baby has grown!
Let it be fun
Smart and happy
Obedient and healthy
Loved by all around!
We are celebrating three years!
We are pleased to note:
Don't call me tiny
How fast you are growing!
Wish you adventure
Children's fabulous moments
amazing wonders,
And toys - to heaven!
Surprise mom and dad
Grandmothers you amuse
Be smart, no doubt.
Happy birthday!
Now the child is three.
Children, whatever you say
Our joy, our happiness
Both outside and inside.
Three is a lucky number.
I want you to be lucky
Constantly. Only "roof"
So that happiness does not blow away.
Let your child grow
So that you do not know worries,
Strengthen and flourish.
Happiness to you - from year to year.
My baby has grown up
He has a snub nose
He has a serious look
Fires in the eyes are burning.
My three year old fidget
Feel free to stomp forward
May from all obstacles and anger
God will save you.
Happy birthday my dear
Be happy, don't be sad
You are smarter than everyone in the world
My bundle of joy!
Three years ago your baby appeared,
And the whole world around changed in the same hour.
We wish the baby to grow up well,
He played football and hockey with his father.
And he built strong sand castles,
I learned the advice of my parents firmly,
So that he only gave a reason for pride,
And he never knew grief and troubles!
Count how many fingers. Come on, together - one, two, three!
Oh, so you’re three years old! Happy birthday! Look,
Three candles are lit on the birthday cake,
Blow on them, and we “Hurray!” we all shout very loudly.
Please us with your smile, do not be capricious, play.
And as you grow up a little, you know and understand everything.
Always listen to mom and dad, never get sick,
With your charm you attract people to you.
Baby, surprise everyone with your achievements.
Let your future success be near in your life.
Smile! Happy Birthday! Let your children's laughter ring!
What can I tell you ... Birthday 3 years is a very difficult holiday for parents. One and a half to two hours spent with children of this age will be remembered for a long time :-).
Why? Three-year-olds still do not feel themselves active participants in competitions. This is bigger spectators, which quickly lose interest in what is happening if you relax a little.
Today I made a selection of entertainment for children of this age (in September 2012 my Vovochka will be 3 years old, I will run the program :-)). In the photo on the left - OH!
Birthday 3 years! Let's have fun!
How to decorate a room?
My huge illustrated article will enrich you with ideas. You can also take a look at .
Who to invite?
Children at this age come with adults. More 4-5 children better not to collect, there will be chaos.
Here is our version of the invitation (I didn’t have time to write, they shot these videos, posted them on YouTube and sent the links to everyone):
When to celebrate?
Better after a daytime sleep - at 16-17 hours. Call for "Merry afternoon tea" :-). Children will not be capricious, not tired, ready for entertainment.
When to give gifts and prizes?
During the celebration, you can only hang homemade medals around your neck.
What to cook and how to decorate the festive table?
Here are my two most detailed articles with a bunch of pictures: and.
How to welcome guests?
Option 1.
Immediately at the entrance, you give a balloon with helium into your hands: “Come to us in a balloon!” If there are a lot of balls, let moms and dads “fly” into the room.
Option 2.
Each guest is greeted by a train. Give the birthday boy some beep (pipe, whistle). The first guest clings to the “train” by the waist, all subsequent guests are new trailers. After the next ring at the door, build the engine again, drive up to the door with a beep and "choo-choo-choo" - escort :-).
Puppet show
This is a good organizational moment. Everyone gathered and sat on chairs. Now it all depends on your acting skills. In principle, you just play a performance with glove puppets, but at the end it is better that the Three Bears or all the heroes of the turnip congratulate the birthday man.
The stores have puppet theaters of various types: magnetic, cardboard, shadow, etc. The cost is from 200 rubles. After the holiday, children are happy to play with all the characters.
Skittles
It's time to get moving! A small bowling alley tour (three attempts each, for example). The ball can be thrown into factory skittles, or you can make your own.
Pour some water (5-7 cm) into 5 plastic bottles or pour beans, peas, pasta or coins for stability. Any ball will do: rubber, plastic.
Before each throw, we count: “One-two-three!” (for three years, after all!)
Teremok
Need an artistic dad. Or grandfather ... In extreme cases, mom in a bear mask. Have two adults stretch out a baby blanket 1 meter from the floor. This is our teremok. All the little baby animals climb into their house and wait for the bear. The clubfoot comes up from different sides of the blanket, pretending that he is about to crush the tower. Children run away screaming as soon as he decides to sit on the "roof".
Be patient, children will make you repeat the action 10 times :-).
plasticine picture
Prepare simple images (coloring pages for the little ones are fine). Pre-warm high-quality plasticine that does not stick to your hands. Distribute to children. It is necessary to pinch off small pieces and lay out a plasticine mosaic along the contour of the picture.
You can draw one picture for everyone - a cake with three candles, let it be a collective work.
edible-inedible
Three-year-old children still do not catch the ball very well, so I suggest put it on the net(if there is no classic string bag, a white laundry bag will do). Let the leader swing the net like a pendulum, and the children will already catch or push the ball away, reacting to the commands “Cheese!” or "Rat!"
face painting
If there is no experience, do not risk painting your face with special paints, the result will not please you or the child. But small drawings on the hand with crayons for the face and body - just right! Flowers, cars, butterflies ... children will be happy to see how you decorate the next guest.
Cheerful orchestra
First, the children need to dress up. Buy ears, noses, masks and wigs, put on caps, funny hats. Now we distribute "musical instruments": whistles, caps, rustling bags, plastic bottles with coins, spoons, etc.
Now we turn on the polka and ... Let the parents help with clapping. Or they shoot this cheerful orchestra :-). Let this birthday of 3 years remain not only in memory!
Bagel
This is such a three-year humor. Parents will also be funny when they see how the children have fun. The bottom line is that you need to answer only the word “BUBLIK” to any question of the presenter:
- What is your name?
- Bagel...
- What did they give you today?
- Bagel...
More questions: What is your favorite toy, and what is on your nose, who is the main character in the fairy tale "Gingerbread Man", what should you say if you were given a gift; what is the name of your kindergarten, what is always in your mother’s bag, what is the name of your dog, what will you take to the sea, what is in your dad’s wallet, and so on.
Only three
Birthday 3 years! You need to remember this number and this number! Prepare 10 disposable plates. Put different items on them in quantity 1 to 6. Children need to make sure that there are only three items in all plates (report or remove).
