Richtextbox instance of string search

I want to get a string from the richtextbox but here how it goes

in programming for example i want to get all class/function and variable names in this given code.

Quote:

---

Private Function Processstring(ByVal strin As String) As String
Dim astrWords As String() = New String() {"parrot"}
Dim strOut As String = strin
Dim strWord As String
For Each strWord In astrWords
If strin.indexOf(strWord, 0) >= 0 Then
strOut = strWord
Exit For
End If
Next
Return strOut
End Function

---

how would i get the "processstring" by getting it after the word function?

i don't understand the question

I'm creating a texteditor and i want to copy all the function names that will be added in the richtextbox.

how would i search for all the function names in the richtextbox if their would be many functions in it?

you could use regex:

vb Code:

Dim rx As New Regex("(?<=(Function|Sub)\s).+?(?=\()")
 
For Each m As Match In rx.Matches(RichTextBox1.Text)
    MsgBox(m.Value)
Next

don't forget to import regex:

vb Code:

Imports System.Text.RegularExpressions

I've added the code in a button but no msgbox that appears.

can you post an example of RichTextBox1.Text?

Return strOut
End Function

just like that.. from that i will be expecting the function name: Processstring

i retried it and it work.. thanks for all.. another one is how about getting variablenames after the dim?

different regex:

vb Code:

Dim rx As New Regex("(?<=Dim\s).+?(?=\b)")

it'll return local variables + arrays

wow! thanks.. do you have any software making the regular expressions?

I'd like also to create regex for c++ variables and functions..

heres some regex help:
