How To Make A Trial Version Of Software
I want to make a kind of 10 day trial of some software I am writing but have thought about the following:

Either I can permanently disable the main functionality so they can get a feel to what the program will do (but can someone hack into a .exe and amend)?

I can install the program and store the installation date and then wait for installation date + 10 days, but if the user keeps amending the system date,it will never expire.

I can install the program again, and store the install date and keep storing the date the program is accessed and when I get 10 unique dates, stop working.

Or I can just limit the usage of the program to 100 uses, incrementing each time the user enters, problem with this, it can expire after 1 day if he goes in 100 times.

Any thoughts appreciated.

I was just woundering if any of you can help me create some code for a registration of my database system.

I have made a program for a company that im currently working for but i have come across a problem where i need to add a registration system.

Trial Software
Before you start flaming, yes I already searched the forum for this. This is sort of an extension without bringing up old topics. I was wondering if anyone knew of a good way to generate a unique key per pc that won't change with the hardware and stuff. Also, what can I do about trial info? Putting it in the registry seems futile because deleting the key would restart the trial. Any other ideas?

Trial Software?
Hey guys I'm interested in learning Visual Basic, but at the same time I don't want to go out and pay the $$$ for the software if I don't end up liking it. Is there Visual Basic trial software out there that last for 30 days. If so could someone point me in the right direction because I have been searching everywhere. I'm sure I will enjoy using it, but I just wanna make sure.

Thanks Guys

Trial Software
I tried to distributing my software as trial version and now I am getting worried because I just know that there is a tool available on Internet called SYM REGISTRY BACKUP which can restore back the previous regsitry value. The problem is that my application store the information for expiration in the registry, i.e everytime the program is started the value in the registry key is incremented and the program will stop to run when a certain value is reached in the registry. I really appreciate for any kind of helps
Thanks and regards

Creating Conditional If Trial N = X And Trial N-1 = X
Hi everyone,
I'm using visual basic 3 to do some data analysis. I already am using a VBAB program which takes my data and creates a variable called "trial" which represents which trial it is in 450 trials and a variable for reaction time on each trial and a variable for type of code (code x, for example, specified depending on RT characteristics in my current program).
What i need to do know is get RT data from instances when I have trial N = code X and trial N-1 = code X (i.e. the previous trial and current trial are both trial type X), then output new variable "code Y". I looked through VBAB help and could not find information on marking data if i conditionalize based on current and previous characteristics on a given two trials.
Any suggestions?

Thanks a bunch!
