Could you please show Example how to use it in the C code?

Is there a way in C to get time from internet?

I haven't studied encryption yet. One of ideas was to use current time [hour:min:sec] as a key to encrypt password. The program will re-encrypt password each 'xx' minutes - the value must be...

Thank you for your reply!
Unfortunately I didn't get an email notification, so I read it just now.
I will modify the code based on your suggestions.

Somebody helped me with this code, now saving array to file works. I added second part - read array from file - compiler complained that something is wrong. Maybe you know where is mistake?

There is a simple C-code, where I defined array of string type. Need to save it into ASCII-file (later I will need to read array back from this file). I know that I did something wrong in 'fwrite'....

Since this thread will not lead anywhere it can be considered as closed.

Discussion went to wrong way because of this ugly person.
He achieved what he wanted.

You are bad person, please don't reply me anymore.

Need to create time (in hours) counter. For example count 20 hours and save intermediate values to file, so will be enough to check time each hour (not each second). Is it possible?

I need to compare current time (seconds since 1970) with time in the future (again, seconds since 1970), where "future time" defined in <y.m.d h:m> format. Thanks

I needed only 'result' from your code. Works great!
Thank you!

WoodSTokk and Nominal Animal, Thank you very much for your help!

How can user pass external variable(s) to exe-file, written on C-language?

Let's say, there is integer variable 'xyz'.

Windows O/S.
What kind of 'encoder' can be used in this case?
Would be great if it could work like a self-extracting archive, which will check the current date/time and compare it with what was set...

Hello,

Let's say I have an exe-file (for example computer game) and need to forbid to run it until certain date or time during the day. Any 'manipulations' with file are allowed. Could you,...
