Some of the more important questions about the Forum!? Come in!

The best way to know the name of the database is to make it more complicated so that no one else can guess the name. Your database should be an access database, if others know the name and path, of course you can**, so in order to prevent **There are many ways, the simplest one is to change the suffix of your database name to. asp for example, if your database is called , change it to.

Of course, it should also be changed in the file-related This can prevent **The reason is because the asp file is to send the data of the execution result to the client after the server-side execution, whether it is opened in http mode or ** they will open it again and then become garbled characters.

There are multiple possibilities for having two databases, maybe your database backup, or just two databases, one user database and one file database, and that's normal.

How to find a virus How to defend is complicated It's too difficult to prevent It depends on who has the best means, if it's your own server, more anti-virus must install a firewall If it's just to do ** Except for the opening of port 80, all other ports are closed and yours If it's an asp file, you should also pay attention to security when writing the program itself.

This kind of thing is beyond ability, and the most important thing is that if you want to do it, you have to spend more time.

Basically, that's all, no matter how good the defense is, someone can break it, and you can try to do it.

When the database is accessed, there will be 2 files, with different extensions, one MDB and one LDB, where LDB is a temporary table, and it will be automatically deleted when the access is closed.

The one on the second floor is too exaggerated, and the master never says that he is a master

It is recommended to change the name of the database, e.g. and then set the file correctly (e.g. conn.).*, find probably** mdb, change it to your database, and analyze the specific situation. ), and quote it.

Two databases are normal, don't worry.

If it's poisonous, you can pass it on yourself, and immediately go and kill the poison, and then delete the horse.

You can change the name of the database, for example, by adding some special characters (!). ·#

If there is a virus in the space, it should not be killed, because if there is a virus, the manufacturer that provides the space should be killed. For servers, you can log in to the server and install an antivirus and firewall on it.

Set the total number of people in the original shouting group x

3 8x+4=4 9(Zheng Wu's x+4).

Get x = 32 and now have 36 orange ridges.

There are 4 points of my personal opinion:

1. First of all, there is no problem with your computer configuration to play this kind of game.

2. Do not modify the priority, which will cause system instability.

3. You can try to update the graphics card driver, and turn off anti-aliasing, synchronization and other functions.

4. There is one thing you may ignore, that is, whether the network is smooth, multiplayer games will have this problem, for example, if one of the 6 of you has a slow network speed, it will cause others to have what you call unsmooth phenomenon because they are waiting for his data. Personally, don't play online games or open other programs that take up network bandwidth.

I hope I can help you, too!

y＝[100-10（x－10）]*x－8）＝（200-10x）（x－8）

10x²＋280x－1600

Its axis of symmetry is x -280 [2 (-10)] 14 at this time y 360

When the selling price is set at 14 yuan, the maximum profit in a single day is 360 yuan.

Profit per piece = 10-8 + x = 2 + x

Sales = 100-10x

y=(2+x)(100-10x)=-10(x-4)2+360 Because -10<0, the maximum value of y is 360 when x=4

Sold per day: 100-10 (x-10).

Profit per day: y = (x-8)[100-10(x-10)] Simplified to obtain: y = -10x 2 + 280x - 1600 = -10(x-14) 2 + 360

It can be seen that when x 14, the function y obtains a maximum value of 360

Answer: When the selling price is set at 14 yuan, the maximum profit per day is 360 yuan.

The mouse started to break, and so did mine, I didn't bother to pay attention to him and smashed it directly, and now the new one is fine. Razer is great for gaming.

Razer has absolutely no problem. FPS games are preferred.
