how to find which line is missing “{” “}”
I want to make a program like Missing Bracket Finder, and I make it, but I want the program to tell me which in line is missing { or }, I'm totally beginner, sorry for my bad english.
This is my code:
Public Class Form1
Private Sub OpenFileDialog1_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk
TextBox1.Text = OpenFileDialog1.FileName
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
OpenFileDialog1.ShowDialog()
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
If System.IO.File.Exists(OpenFileDialog1.FileName) Then
MsgBox("Number '{':" & System.IO.File.ReadAllText(OpenFileDialog1.FileName).Count(Function(x) x = "{") & " " & "Number '}':" & System.IO.File.ReadAllText(OpenFileDialog1.FileName).Count(Function(x) x = "}"), MsgBoxStyle.OkOnly, "Info")
Else
MsgBox(TextBox1.Text & vbNewLine & "File not found." & vbNewLine & "Please verify the correct file name was given.", MsgBoxStyle.Exclamation, "Open")
End If
End Sub
End Class

yes hi,
This is an easy trick, common and used everywhere in those programs and debuggers. You just set a counter for each type of braces, add 1 when it's '{' and substract one on the opposite direction. Line you won't get, but approximate solution will work once you reach out negative values, you should always get 0 in the end and never have negatives. If you want line anyway, just only empty spaces. Count empty spaces and work out your braces counting along with that, but it's not recommended.

Let it one and half year from now, I believe it is not slightly the time for you. I can describe the solution as I said in one sentence, but the code is usually not one sentence at all.
