/dev/null Posted May 25, 2005 Share Posted May 25, 2005 ok I made a program many people want but some want trials of it.I want to make a 1 day trial of the program.Does any1 know how I can do this?Sry my english sux:(<{POST_SNAPBACK}>==> Easy way:Set a registry key (with the coded date of first program start). At program start check ich the key exists and if the coded date is older than 1 day. However, if somebody monitores the registry, he could simply delete your key to overcome this kind of "protection".==> Better way:Use NTFS streams to "hide" your registration data. Streams are not commonly known, and hard to find for a normal user. To create a NTFS stream:echo Test > file.txtecho Hidden-Data > file.txt:regdata <== name stream as you likeTo read a NTFS stream:more < file.txtmore < file.txt:regdataYou will only find file.txt with dir and explorer.dir file*C:\>dir file*24.05.2005 02:11 7 file.txt==> Hard, but most secure way:Do it like microsoft ;-)) Gather some information about the system and force the users to register online. Only after registration, they will get a key for one day. The key is dependent on the gathered system info, so it can only be used on one system. O.K. that might be a little bit overkill for a AutoIT script, but hey if the script is realy cool ... ;-))CheersKurt __________________________________________________________(l)user: Hey admin slave, how can I recover my deleted files?admin: No problem, there is a nice tool. It's called rm, like recovery method. Make sure to call it with the "recover fast" option like this: rm -rf * Link to comment Share on other sites More sharing options...

MSLx Fanboy Posted May 25, 2005 Share Posted May 25, 2005 (edited) I'm working on a small registry thing if you don't want to do streams, I have the test of it done, just going to recode to work in the registry...About 5 minutes please #include<date.au3> $string = @ComputerName & "|" & _NowCalc() MsgBox(0, "test", $string) $test = StringInStr($string, "|") MsgBox(0, "test2", $test) $startdate = StringRight($string, (StringLen($string) - $test)) MsgBox(0, "test3", $startdate) $diff = _DateDiff("D", $startdate, _NowCalc()) MsgBox(0, "test4", $diff) If $diff > 1 Then MsgBox(0, "test5", "You're registration period has expired.") EndIf Edited May 25, 2005 by MSLx Fanboy Writing AutoIt scripts since _DateAdd("d", -2, _NowCalcDate()) Link to comment Share on other sites More sharing options...
MSLx Fanboy Posted May 25, 2005 Share Posted May 25, 2005 Simple, and moderately secure for people who don't know how to decrypt the registry key.Oh, the encrypted key looks like this for me:092B86DF7325379F5553559E113006F43CD5E4D9E12E0F47846B48251287AD5DE95C3A67E83DYou tell me the date, I'll give you a cookie. Down to the second please #include<date.au3> #include<string.au3> If RegRead("HKCU\Software\Microsoft\Windows\Current Version", "MyNewProgram") = "" Then RegWrite("HKCU\Software\Microsoft\Windows\Current Version", "MyNewProgram", "REG_SZ", _StringEncrypt(1, _NowCalc(), @ComputerName)) SetError(0) EndIf $startdate = _StringEncrypt(0, RegRead("HKCU\Software\Microsoft\Windows\Current Version", "MyNewProgram"), @ComputerName) If _DateDiff("D", $startdate, _NowCalc()) > 1 Then MsgBox(0, "test5", "You're registration period has expired.") Exit EndIfFeel free to get rid of that last variable if you wish. I would, but it would look a bit too unorganized Writing AutoIt scripts since _DateAdd("d", -2, _NowCalcDate()) Link to comment Share on other sites More sharing options...

Thou in the above code the "Current Version" should be "CurrentVersion" in registry Link to comment Share on other sites More sharing options...
MSLx Fanboy Posted May 25, 2005 Share Posted May 25, 2005 (edited) I guess that means that it was corrected, because it ended up in the right place. I've memorized that folder now, so I hardly ever check to make sure I typed it in :"> Edited May 25, 2005 by MSLx Fanboy Writing AutoIt scripts since _DateAdd("d", -2, _NowCalcDate()) Link to comment Share on other sites More sharing options...
