About software design after the completion of the trial version of how to control the time

Time:10-04

I want to control the duration of the trial is a month how good control of time and not easy to be cracked thanks
If you have this small program my tank: [email protected]

CodePudding user response:

Don't be cracked really difficult, leak a lot

CodePudding user response:

You do more complicated somebody else can break, besides PB can be decompiled.
Than simple point: die hard code have jiao date. Such as in the code written to death before the date of January 1, 2008 can be used. If expired hint he contact you, or to download address to him.

Have any PB can master to moonlight as a training instructor? If an interested friends, please send resume

reasonable

CodePudding user response:

There are some controls, such as ActiveLock what of, use them yourself, you could save some time, of course, there is no impregnability of wall, enough is enough

CodePudding user response:

Directly from the server time
If really to use, the server time is not literally callback

refer to 7th floor madalin response:
no impregnability wall in the world, enough is enough to go

It's hard to be cracked

CodePudding user response:

Installation time encryption records to registry or file, to read the installation software startup time and machine time now, judgment time interval due to decide whether to try, but that changed the machine time is bad control, suggest you control line data window display data better, more than how many lines won't let show ~

CodePudding user response:

Control the number of lines, it seems that also can yet be regarded as a good way to

refer to the eighth floor SBKS response:

directly fetch the server timeIf really to use, the server time is not literally adjustable

UP to THIS.

CodePudding user response:

First run time recording system, and then encrypted in the database, at the same time put due time also encrypted in the database, later time directly with the judge.

CodePudding user response:

Good relations with customers, and make them pay on time

That's a good way to

This is no good, do it before, the event viewer, traceable to what position do you write in the database,

Unless the condition of multiple related, mutual linkage.

Reshipment?

CodePudding user response:

Control record number is a bit better, or use the date encryption into registration code,

CodePudding user response:

To achieve with pb, too easy to be cracked,

There is only one way to do better, is in many places would have to use long, you are using an int type, when the record is beyond the scope of type int, will go wrong,

I agree with this method, with most of the people know that the time range, with a number of records is a good point, don't look not to come out the compiler,

CodePudding user response:

Is there any way to join in program code, once be cracked software open deltree before the open?

CodePudding user response:

It is recommended to use with clock can, can prevent the decryption, also can solve the problem of clock
