how can i find 2 char with a specific number of line between them please see the screen shoot

This regex might work:
B\n[^\n]*\n[^\n]*\n[^\n]*\n[^\n]*\n[^\n]*\n[^\n]*\n[^\n]*\n[^\n]*\n[^\n]*\nB
B is the letter B
[^\n]* is any amount of anything that isn’t a newline
\n is a newline
Thus, this will find two Bs with exactly 9 newlines in the text between them, no more or less.
This will also find Bs that have other Bs between them in these 9 lines. To fix that, change [^\n]* to [^B\n]* so that any of the lines between the two Bs cannot contain B.

@saiapatsu thank you for fast replaying , it didnt work i tried also B\n[^\n]*\nB means one line between them right? it didnt work neither

@saiapatsu i guess there is somthing missing in the start of your regex

@saiapatsu said in how can i find 2 char with a specific number of line between them please see the screen shoot:

B\n[^\n]*\n

i got it at the start [B\n[^\n]\n… i had to remove the \n so it looks like this [B[^\n]\n…

thank you very much

@qishq-42
im wondering how can i find it in this situation

@qishq-42

If you had 5 lines between the ones that started with the Bs, you could use this:

(?-s)^B(.*\R){6}B

Note that the 6 relates to the 5 you want – it is one more than the desired.

@alan-kilborn it is working! Impressive! thank you man

@alan-kilborn one question how can i exclude the B from being in one of those 5 lines?

I suppose you then want this?:

(?-s)^B([^B]*\R){6}B

Suggest you read about regex and Notepad++ starting with references HERE.
