Checking data for relevance. How to implement?

Question

C++ / C#

Good afternoon. I have an application that pulls data from another program with a delay of 100ms.
All this is wrapped in a method with type string.
The label of the window displays the value of this method. For local use, this is enough for me, but I want to transfer these values ​​​​to my site or VKontakte.
I still agree to send data every 100ms to my site, but Vkontakte will definitely not understand this.
How can I do a data comparison? For example, as soon as the data has changed, it is sent to avoid spam with monotonous values.

Answer 1

as an option: at each iteration, store the received data and compare them on the next. iterations. if they differ, then we overwrite, form a string and send it wherever you want (VK or your site, it doesn’t matter). Well, you know better how to compare them.
