How to add a charging system to the software with Easy Language?

What is the software charge? Think of your own ID, SN algorithm first, and then when your software is running, first judge whether SN exists, whether it is expired, whether it is correct, and the verification is unqualified and will end directly, the key to this is in the design of your algorithm, no one can help you, send you a set of I used it:

The first count cycle (32, n1).

SN = take the middle of the text (take the file summary (id) + take the file summary (my birthday), n1*2,1).

Count the end of the cycle.

It's simple, but it's also practical.

SN is your serial number,ID can be taken CPU hard disk and other numbers to be processed (I still use the above algorithm to get a 32-bit string) to get,To ensure that the stand-alone machine is used,You can also count the SN belonging to this username according to the user's own user name to find you to apply for (just like Rising),Everything must and can only be designed by yourself and cannot be known to outsiders。。。

ps:It's easy to crack the software now.,This charge.,That's it.,Don't take it too seriously.,Otherwise, it's our programmers themselves who suffer.。。。

This algorithm sounds complicated, to calculate is very simple, the prime minister needs to add a to judge whether the software is registered, it can be the title of the startup window, or it can be to judge whether the registration file exists, and then the above conditions are used as registration conditions, if it is not established, it needs to be registered, the registration code can be a number, letters, of course, it can also be Chinese characters, the content of the registration code can be written by yourself, it can also be the CPU serial number, of course, it can also be the hard disk feature word, and then enter the correct content to write this content to the file, Next time you judge this file, I can give you the source code if you need it.

Find a third-party payment and embed ** into the program after opening.

v Gurgling.

Open () or Execute ().

This algorithm sounds complicated, to calculate the judgment is very simple, the prime minister needs to add a lack of trouble to judge whether the software is registered, it can be the title of the startup window, it can also be bent to judge whether the registration file exists, and then the above conditions are used as registration conditions, if it is not established, it needs to be registered, the registration code can be a number, letters, of course, it can also be Chinese characters, the content of the registration code can be written by yourself, it can also be the CPU serial number, of course, it can also be the hard disk feature word, and then enter the correct content to write this content to the file,Next time you judge this file.,I can give you the source code if you need it.。

It feels like this thing is a **, and it's better to write it in ASP or ASPX.

Have you set up an FTP server yourself?,If not, set up one.,And then fill in the IP address of your FTP.,Fill in the username and password of the "31" and "meina520" and so on. To sum up, there are several reasons for connection errors:

1. FTP server is not set up (that is, FTP server is not created using the filled IP) Solution: There is FTP space setting software on the Internet, which is very simple.

2. Fill in the wrong username and password. Solution: Fill in the correct username and password.

3. Fill in the wrong IP (that is, your FTP server has been created, but you have not filled in the correct IP) Solution: Just fill in the correct IP.

PS: I don't recommend you to use FTP space, because everyone's IP is a dynamic IP, and your network will be assigned to your other IP if you connect to the network, and others will not be able to connect, so it is recommended that the landlord rent a server by himself. If you don't have money, you can set the parameter of "IP address" as a variable, and then use the peanut shell software to automatically read your current IP, and then send data to the client, and then the client can parse your current IP on the peanut shell, which is more troublesome, and it is recommended that the landlord rent a server.

The IP address will change, if you don't believe that you connect after disconnecting, the IP address will be different, we use dynamic IP....

Is the server confirmed to be your own?

Someone else's source code doesn't seem to be able to connect according to your username and password above.

You go to search: EBC Network Verification System. This system is specially used for software charging, such as adding recharge, registration, and point card functions to the software.

.Version 2

If the registration entry exists (4, "Software Microsoft Windows CurrentVersion Explorer Advanced Folder Hidden ShowAll CheckedValue Shijian") is true).

A takes the text registry entry (4, "Software Microsoft Windows CurrentVersion Explorer Advanced Folder Hidden Showall CheckedValue Shijian"), B to the text (takes the day (to the time (a))).

If (to the value (to the value (to the value (take the day (take the current time () to the value (take the day (to the time (a)))2).

Load (Window 1, true).

Launch the window. Destroy ().

Otherwise, launch the window. Get Focus ().

If it ends. Otherwise, write the registration entry (4, "Software\Microsoft\Windows\CurrentVersion Explorer Advanced Folder Hidden ShowAll CheckedValue Shijian"), to the text (take the current time()).

Launch the window. Get Focus ().

Window 1 is the charging effect.

And there is no network verification.

Try it free for 2 days.

Easy Language itself does not have network verification, and network verification is generally a third-party program.

I've written a commercial network verification program, which is not bad, you can refer to it.

KSreg Network Verification System Official**:

Buy a web host and upload the network verifier to FTP

There are a lot of network verifiers to search for the source code.

Same as software registration, send you the computer machine code, and send a string of registration codes through a specific algorithm, and fill it in before you can open and use the software. The idea is this, and the specifics are more complicated. Don't ask how to do it, it's rare to type and learn slowly online.

Add the username and password directly to the database connection string.

Put a lot of usernames and passwords in FTP,When the customer logs in,You can read the file list,Verification,,It's not good to put a lot of usernames in a file,After more customers,The file will be very large。

This is most likely caused by incompatibilities in the computer's operating system or configuration, and the server can sometimes be used during debugging, but once it is compiled, this problem is easy to occur. I've had a few times, I don't know if it's because of the incompatibility of the server, but it's reliable to try it by chance.

Do you have a router at home? If so, please ask, I'll give you a solution, if not, please ignore it, because I don't know how to do anything else!
