help with trial limit script

Recommended Posts

Hypertrophy

hi i am having trouble with this script. it uses registry entries to determine how long the user has been using the software and after certain time or if user tries setting back the clock it expires it and you have to register. problem is it always says the trial period is over when there are no keys in the registry indicating so. can you please help me.

Why not? Its a proven system that works very well... :)

I already posted that? :)

Sorry, you post just link I didn't know that is XProTec.

Hypertrophy, I tell you a few words about your security system:

This can be simply hacked! - More fixable - is to lock some function of your code and make demo version.

In this case, never lock(or hide) controls by GuiCtrlSetState!! - use code verifying before control creation or function execution or something else.

I see, you want to make product for sale...

Note: According to the "license" you have no right to add your ©copyright, because an absolute author of all that we "compiled" - is ... you know who...

I know it can be simply "hacked". The only way that I know of though is just to delete those 3 keys in the registry. I am aware of that. And yes I did take precautions in case it does get hacked. Every now and then when creating controls it will check to see if the software is registered. If not it simply won't create those controls. There is no hiding. I don't need XProTec. I opened this thread for issues with my code not XProTec so I'd appreciate advice if anyone has a solution.

I don't know why your request is being ignored.

I think the problem is this line

$expired = _StringToBoolean(BinaryToString("0x"&RegRead($trialKey,"id")))

If you don't read anything at the reg key you are getting the boolean value fromBinaryToString of "0x" which I think you think is false, but it isn't.


Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

Thank you martin for replying. And I've also suspected it being that line because $expired always returns True it seems.
