I'm an old software design engineer. Actually, my English is not that good, you should be able to find mistakes easily. I'm using English most of the time just because typing English is much faster for me. If I type in Chinese, I would be 5 to 10 times slower.

I have not attended one day school outside of China, but I joined HP first before joining Microsoft. I know some people transferred from Microsoft China to US. Not sure about hiring directly from China. A few days ago, there was ad about hiring people from Asia directly to Microsoft US.

If you stay, do you think the project can be finished, the company can make money, and you will not kill yourself from overwork? Leave if the answer is no, or most likely no.
If you want to stay, talk to your boss about your new job offer, asking for a salary raise and/or change of responsibility (promotion).
If you want to leave, think about who can replace you, offer to help consulting in your spare time.
Working should be more than just the salary. What is very important is improving your skill so you can get a better job.
If your job is so demanding that you can't live a normal life or having time to improve yourself, consider changing it.

Suppose minimum wage in China is 500 per month, making 5K per month would be 10 times minimum wage, making 10K per month would be 20 times minimum wage, making 20K per month would be 40 times minimum wage. Is 40 times good enough for your 钱途?

Microsoft is working on WinFX, a totally new set of features based on managed code. So it's assessable through C#, managed C++ and VB.net.
WinFX will be shipped independently of Longhorn, so it can be installed on other version of OSes like Windows XP.
Part of WinFX is Avalon, the new graphics/user interface/document/printing API for Windows.
With Avalon, programmers can write very cool client side applications.
Read: http://msdn.microsoft.com/longhorn/understanding/pillars/avalon/default.aspx
If you have a good computer science background, learning a new programming language is easy, one month to two months.
But learning the whole Windows API is hard, or almost impossible. You need to focus on a few basic areas first, KERNEL, USER and GDI. For the rest of stuff, learn them when it's needed. For example, you do not need to learn Winsock unless you're doing network programming.
Microsoft mainly uses C, C++, and C#.
But during interviews, we usually do not care what programming langauges candidate use. They can use the language they know best to finish interview questions.
Learning a programming language is easy, write production quality code is hard.
I got into small troubles for writing:

One important variable missing is you.
Do you think you're a good software engineer or you want to be a good software engineer? Do you want to be among the best? Or do you just want a comfortable job living in the same city you grew up? What do you want to do in 5 years?
Do not think this job will be your job for the life time. Just assume that you will work there for 2 to 3 years and move to another company. Then decide which company will give you the most experience to achieve your 5 year goal.
1. Check your eyes every a few years, you may need a new pair of glasses.
2. Move your eyes away from computer after 20 minutes. This is what I can see from my office: http://www.fengyuan.com/lakebill/
3. Keep safe distance from screen. If you can't see clearly, use a large monitor, increase font size.
4. There is more than programming in life, enjoy it.
I still have most of my hair after so many years of programming.
As the company is listed on stock market, they have to do something to please the stock holders. Otherwise, stock price will fall even more and more people will lose jobs.
There is not much difference in male/female software engineers, just do not work for a job which needs crazy working hours.
If you have to work 60 hours a week for a long time, look for a better job.
Why do you need to use bitmap in the first place?
For scrolling, you should use ScrollDC and then just repaint the newly exposed window.
Why do you want to write another editor?
1) Show your code.
2) Measure the performance of your code.
3) Setup a goal on how fast do you want it to be.
I've read some of your code. The basic scrolling code is:
ScrollDC(GetDC()->m_hDC, 0, ScrollLines * GetLineHeight(), &mClientRect, NULL, NULL, &rect);
InvalidateRect(&rect, TRUE);
UpdateWindow();
I do not need bitmaps being used.
1) How slow is your current code? Measure it.
2) How fast do you want your code to be? 100% faster, 200% faster.
3) Measure now much time is spent on ScrollDC. You have no way to improve it, except to minimize its area.
4) Check whether rect returned by ScollDC is right
5) UpdateWindow should call your OnDraw routine eventually. A faster ways is just call OnDraw, or functions called by it directly.
6) Check if the parameters passed to OnDraw is optimal.
7) Measure how much time is spent within OnDraw, check how can you reduce the area, how can you improve speed.
BTW, what is the design goal of your code? Do you want it to be able to print? If so, you should avoid using DrawText.

To be more precise, lots of things are possible, but there are certain things which are impossible. You have to learn when to try, when to give up, when to undo, when to change direction, and when just to enjoy life.

2. An immature person models world using single variable, a mature person models world using multiple variables.
3. An immature person sees world as a static picture, a mature person sees world as continuously changing. It has a past, a current state and several possible future states.
4. An immature person likes to blame other people or the environment, a mature person will look into himself/herself for possible changes first.
5. An immature person gets frustrated from mistakes, a mature person learns from mistakes.
6. An immature person sees world in single layer, a mature person sees the world in multiple layers of abstractions.
7. An immature person looks for simple definitions, rules, or guidelines; a mature person can see way beyond those simplifications and get the true meaning behind them.
8. An immature person would wait for 伯乐 to find him/her; a mature man knows there are so many opportunities ahead, he/she just wishes there are multiple lives to try them one by one.
9. An immature person would BS other people a lot, a mature person learns from any people better than him/her.

Yes! My code is running in HP calculators, HP deskjet printer drivers, Windows XP, and later Longhorn/WinFX.
Programming is fun because it's a perfect combination of science, engineering, art, detective work, etc. It's a team work, yet individual can contribute a lot alone.
>> 苦 无穷无尽的加班熬夜做伴，
Do not work over 60 hours a week. 50 hours a week is still okay. Find a good company to work for. The only time I worked 80 hours a week for long time is when I wrote my book.
> 辣 让程序员成为了一个吃青春饭的职业。
Do not work too hard, find a good company, then you can work a long time.
> 三天后，我就不是程序员了。
Good luck. We will still welcome you when you decide to return.
> 我并不是做不好coding，事实上只要愿意，我能够靠coding进入相当好的公司，拿到相当高的收入。coding也并非没有前途，实际上，如果好好的做，到外企，或者拥有真正核心技术的好公司，还是很有发展的。
Much better. This give hope to new programmers.
> 不过，coding太依赖于外部环境，依赖于好公司、好老板、好市场什么的，程序员很少能够自己决定自己的未来。这才是我离开coding的根本原因。
I do not know what other fields offer freedom than programming. But anyway, good luck with your new career choice.
1) Programs are universal. Good programmers can find job anywhere in the world.
2) Every field is trying to reducing cost, so use computer to automate things used to be done by human is a good way to reduce cost. So essentially programmers are eating away other people's job.
3) Computer hardware is still evolving at rapid speed to be cheap and better. So there are more and more places with computers being used, which means more jobs for programmers.
Sometimes ago, people in US killed all the wolves in national parks. Then the deer were very happy, because there is no one to chase them around. They have all the time to eat tiny young trees. So they became fatter and the forest suffers too.
To solve the problem, people brought wolves from Canada to US. Now the deer are not safe any more. They have to run around to get away from wolves, the weak ones will be killed by wolves. They also do not have time to eat tiny young trees. The result is healthy deer and healthy forest.
If your job is too boring, find a better job and quit it. Three years ago, I left HP to work for Microsoft. Now I have endless interesting code to write.
Spending 15 hours before computer is too much. Get a life. Do something else. Besides job satisfaction and contributing to society, working is really to get enough money to live a good life. Make some friends, go out to do fun thing. If you like to stay indoor, do something like playing Go (Weiqi). I almost play everyday.
Self-confidence can be regained by setting up a goal and achieving it; then you move on to the next goal.
Do not waste time, do not waste your life.
The key thing here is not age, it's find a good company to work for.
Do not work for junk companies. Improve yourself and leave.
Once you find a good company to work for, then decide what kind of job you like most and you're best at. As you improve yourself, you can certainly change your jobs within the same company or even find a better company.
Do not just say you want to be a 系统分析或项目经理. You need to be able to do the job and like doing the job, and the company needs to make money. Job title is not that important.

1. You need to work in the right direction.
2. You need to work smart.
3. You need to re-evaluate current situation and adjust accordingly.
Wrong question to ask, for an adult.
First you have to define what is a good life for you. Then you have to ask yourself how to achieve your 'good life'. After that, you have to take actions to realized your dreams.
If you just sit there and waiting for your life to be better, you will be doomed.
There are things you always needs to learn, no matter what OS you're on and what language you're using. You can call those thing 内功:
math, logic, language skill, presentation skill, personal skill, discrete math, data structure, algorithm analysis/design, object oriented programming, design pattern, ...
Things like OS, specific programming language, specific programming tools, specific API can be called 外功. You just need to learn them to achieve your short term goals, like getting a job, move to a new job, getting a raise, ... You do not need to plan for more than 5 years on those things, because things change so rapidly.

You have to give your boss enough reasons to raise your salary. For example:
1. I have worked for your company for N years and I think my skill has improved a lot, so I think I need a raise.
2. I'm more productive than Mr.X which earns higher salary than me, so I think it's fair for me to get a raise to get closer to his salary.
3. My friend is working in another company with higher pay, but I really like working here, the only problem is that ...
If your current salary is 10w, if you increase your salary every year by 30%, 5 years later, you will be earning 37w. But increasing salary by 30% every year for 5 years is very hard.
You need some drastic change in your life to achieve that number in 5 short years.
You're lucky to have extra time and nothing to do.
1. Think what do you want to achieve in your career within 5 years. For example, you can say you want to move to a company with 100 software developers and double your salary. Then figure out how to achieve that goal.
2. Make more friends.
3. Enrich your life. Learn something new and fun, for example play Weiqi, learn painting, learn dancing, learn gardening, sports, ...
4. Help poor people.
If you want the best job, English listening, speaking, reading and writing are all very important.
Reading : gaining knowledge
Listening/Speaking: informal communication, job interview, presentation, conference.
Writing : office communication, writing articles, papers, books

Programming mistakes?
If it's programming mistakes, do not blame yourself alone. All production code should be code reviewed by another person and tested. Otherwise, your development process is wrong.
Remember what you have written today. Print it out. Hang it on the wall.
You will be a better man the day you feel shameful of those words.
如果别人乱装你们公司的软件, 你还有工资吗?
The best is get both, love programming and make a good living from programming. I think I have reached this stage more than 10 years ago.
To gain satisfaction from programming, you need to improve your math/programming skills. After your skills are improved, move to a better job.

Check for /Gh compiler option in VC. A call to _penter will be added to each function. Then you can do stack measurement there.

If your program has recursive functions, it's very hard to do static analysis.
If you just want stack usage for each function, you may be able to get information from .map file or debug symbols.

4 years teaching, 2 years small company, 8 years HP, 3 years MS. Life is good.
The cost of owning a property is not the price, it's mainly interest and property tax. If you make the right choice, you should be able to sell the property later to get back the money you spent and possibly some profit.
For example, if you buy a 500K house, 400K loan, with 5 percent interest, monthly interest payment is 1.6K. That is the only you really spend. The money spent on reducing loan principle should be considered a form of saving/investment. You also need to consider how much money you can make from the down payment you put in.
房子奋斗不完的. 过几年可能换工作, 可能嫌小, 可能钱多想投资, 又要换房.
Moving from 4000 to 5000 is a quite reasonable goal. First, you need to determine whether it can be achieved within your current company. For example, is your boss' pay over 5000, or is a more senior person in your team making that much. If so, you just need to improve yourself to that level.
If it's too hard to achieve in your company, then you need to start look for another job. Find a better company, find an interesting job opening, then try to work towards their job requirement.

I would agree with your father, get a job first. Prepare for master degree in your spare time.

Software is unique in that it has large development cost but very low reproduction cost. So volume is the key to success.
Do not create another tiny software company just because you want to the boss, producing some more low quality software and hiring more unhappy programmers.

Why such an expensive car? I'm stilling driving a car bought at only 15 万 7 years ago.

This sentence is quite vague. There is no supporting evidence. Both 突破 and 定型 are not easy to define.
You should have asked your teacher what 突破 has you made in the last three years.

Design a language is easy, writing a compiler is easy, getting people to use it is hard.
But if you really want to write compiler, there are something interesting to do.
Do not design a new language, design some extra add-on features to a language and then have your special compiler/translator process them.
For example, design something on top of C++ and let your compiler/translator translate it into MMX/SSE/SSE2 instructions.

Try to learn something about everything and everything about something. Thomas H. Huxley
There is nothing to be proud of using parents' money. There is nothing for you to envy.
If you're looking for sadness, go for it. But you should instead focus on what you have and focus on what you can do to change your situation, do not blame your background, do not blame your family. It's your responsibility to change your life.
There were two processes A and B running in the system, happily communicating with each. Now all of a sudden, process C comes to life and process A starts talking with process C instead.
Now process B is trying to figure out how to get process A back.
Suggestions:
1) Debug process A to see why it stopped talking to process B. It may be a bug in process A's source code. Make a suggestion to process A to fix it.
2) Process A may say that the problem is really caused by a bug in process B, or there are bugs in both A and B.
3) Evaluate the cost to fix problem in A, or in both A and B. If the cost and schedule are reasonable, fix it/them and continue; otherwise, disconnect from process A and start looking for another new process.
Do not blame your environment too much, you can basically improve yourself anywhere.
Do not change job for the sake of change.
What I have done several times is:
1) Do the best at your current job.
2) Learn something new for your next job in mind.
3) Switch to your next job.
If your IQ is above average, work hard and work smart, you will be surprised at what you can achieve in 10 years.
But work is not everything, enjoy life too.
