c# - How can you match words with more than one character? -


I would like to use a regular expression to match all the words with one more letter, the same four.

It should not match: ttttt, rrrrr, ggggggggggggg

This should coincide: rttttttt, words, wwwwwwwwwu

The following expression will be a move. 

  ^ (? & Lt; first & gt; [a-zA-Z]) [a -ZA-Z] *? [  
  •  Capture some more letters (to avoid recurrence of negligence)  
  •  Make sure the next character is used by  FIRST  using a negative attribute 
    •  
  •  Capture all (due to at least one claim) remaining characters 
    •   
     Note that searching for a different character than the first characters is sufficient because If no character is different from fi Rst is the same one all the characters. 
     
     You can shorten the expression to the following. 
     
      ^ (\ w) \ w *? (?!? 1) \ W + $  
     
     This will match some more characters than [a-zA-Z].

    I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%.
