After trial period finish (30days) software moved to ProductCode Page, where technical support department will provide License # for rest of the period this product code generated in KeyCode generated.
Is there anyway I can provide that code which will allow end user to utilize the code for rest of the life of software.

Thank you very mucch.

After 30 days trail period over the Productcode Page will pop up, which will ask end user to insert product code in the form. This Product code will be generated in KEYCODE GENERATOR.
My question : since the trial period is over there is no return for customer. How can I give full permission on new software to end user from KEYGENERATOR and remove Date from registry and give new date to new software from code mentioned below:

Most interesting, do you have a question?

Vijay Pate 3-Oct-11 13:21pm

I need to add SystemDateTime or curentdatetime to Registry with this code.

Richard MacCutchan 3-Oct-11 14:37pm

OK, and what problem are you having that prevents you from doing it?

Vijay Pate 3-Oct-11 15:49pm

I dont have any experience and I am getting road block when assigning the value.
Thank you very much.

Chuck O'Toole 3-Oct-11 16:10pm

I assume that phrase "when assigning the value" means something to you. It means nothing to us. We do not know what is in your mind. So, explain it as if the person you're talking to has no idea what you've tried or what error you've recieved or what conceptual road block you've hit. You have got to give us more precise information about your problem.

Richard MacCutchan 4-Oct-11 4:19am

Well I can only suggest you remove the road block and try again!

If you really expect people to help you with technical issues then learn to describe your problem in technical terms. Show the code that you are using, including the values of any variables etc. Explain what you expect to happen, and what actually does happen, including any returned error codes or messages. Vague statements such as the above don't help us and just waste your time.

Vijay Pate 4-Oct-11 9:11am

I am trying to add SYSTEMDATETIEM and I have never done this in C++ but I have done this in SQL or ORACLE, there is something you can help me to get this done with C++ code I have sent you?

Thank you very much.

Vijay Pate 4-Oct-11 9:51am

my only concern is how c an I write function to convert ctime to SYSTEMTIME and where should I specify that in the code I sent you.
Thank you very much.

Vijay Pate 4-Oct-11 10:00am

I ment write function to convert srting into SYSTEMTIME
after that give a parameter to date in string like ('yyyy/mm/dd') as ctime to dtSystime = systemTime to return dtsystemtime

Chuck O'Toole 4-Oct-11 10:38am

Go to MSDN or Google the CTime class. The various constructors allow for interpreting time input in different forms. Then look at the GetAsSystemTime() member to convert to a SYSTEMTIME object. The GetCurrentTime() will get you 'now'

Chuck O'Toole 4-Oct-11 10:41am

PS, when you reply to someone's question, use the "reply" button/icon on the right side of the question you are responding to. In that way, the person will get an e-mail message that you replied to them. That doesn't happen when you use the "Have a Question or Comment?" so you're reply will just sit until somebody comes back to check which may be a long time coming.

Vijay Pate 4-Oct-11 10:42am

Thank you for heads up and GOD BLESS YOU

Vijay Pate 4-Oct-11 15:16pm

Do you have any example I can view for the subject.

Chuck O'Toole 4-Oct-11 15:29pm

MSDN has examples for each call on the pages that document the calls. Have you looked there yet? As for what you have to write to the registry, I have no clue, it's your assignment, I assume your boss and/or project leader told you that already.

Vijay Pate 4-Oct-11 15:31pm

no

Chuck O'Toole 10-Oct-11 18:04pm

Ah, now it sounds like you are trying to hack the registry to get around a trial license for software that expects payment for full usage. Please tell us that is not what you are trying to do.

Most of us are professional programmers, we get paid for our efforts. Circumventing product licensing takes food from our children's mouths. You won't get much help for that kind of thing here.
