Well, without a crystal sphere to read your mind and the future it is impossible to help you.

Providing more details is surely a remarkable idea, don't you think?

What do you want us to do about your question? Maybe you will need something like this one...Dave has done a video about it.
Next time, please expand or give details to your question...Even if your not a native English speaker, we will try our best to understand it as much as possible.

Is it just me or has the average intelligence on this forum fallen in the last 6-12 months? Do people not know how to communicate anymore?

I just dont answer questions for people, who have less than 5 posts on the forum. Its only fair. Unless the person manages to show some actual competence in the post.

I'm just going to leave this here, with three notes. A) all values are example only and in reality you will need to pull reset/set low. B) you may omit the relay entirely if the load is small enough. C) It doesn't hurt to put SOME effort into asking for help.

Tis dis new 420 internet culture man, it be like totes rad man. (EDIT: how many brain cells did I kill with that...;D)

But seriously, can we get an update to the rules that says that if the thread is not a link/video, that it has at least an attempt at a complete sentance.

In one of the other electronics forums which I attend, a couple of years ago, there was an even worse post:

The title was related to some power supply question, and the message consisted of a single and lonely ?

This one's even more simple but the resistor values may need to be tweaked a little to get it to work.

sorry i dint told you me problem
really really sorry
i actually wanted to create a simplest soft latch circuit by using ics not transistor or resistor or capacitor
i have found the solution
the solution is using D flip flop

I dont know if its coincidence or not, but I seem to read alot of questions asked like this by people that live in India or the Middle East. No context, no details, just wanting spoon fed information. Maybe its a cultural or communication difference? Okay back to your normally scheduled programming now....

There was a power latching circuit here I think:

Should be enough for you to get an A++++++++ on your assignment.

Danger in your attached schematic...  If there is a substantial charge in the 1uf, say the system +V is 50v, you will potentially blow the base of the NPN transistor.  For low voltages, the circuit should be fine, or, add a series resistor on the button when operating above 12v.
