'Visual basic (.NET)
'Define library for read files
Imports System.IO
Public Class ETable1
Private Sub Button2_Click_1(sender As Object, e As EventArgs) Handles Button2.Click
'Identifier variable for file path that the user selects
Dim x As String
'Choose text file
OpenFileDialog1.Filter = "TIFF(*.txt;*.txt)|*.txt"
'If user choose text file the code will be run
If OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
'Store file path
x = OpenFileDialog1.FileName
'Identifier variable for store lines value
Dim lines() As String = IO.File.ReadAllLines(x)
'Delete data from list
'Read files from text file
End If
Catch ex As Exception
'If file doesn't chooses or not found
MsgBox("file not found &   check the filename and try again", vbCritical)
End Try
'Identifier variable for store lines count
Dim DCount As Integer
'Identifier variable for store lines count value
Dim Row As String = ""
'Identifier variable for read file
Dim CSVReader As System.IO.StreamReader 'Puts file in CSVReader for Sorting
'Store file in Identifier variable
CSVReader = System.IO.File.OpenText(x)
'Read file
Do While Not CSVReader.EndOfStream() ' Loops until end of file or Stream
'Store lines in Identifier variable
Row = CSVReader.ReadLine()
'If row is not empty read line or  comment line
If Row <> "" And Mid(Row, 1, 1) <> "'" Then
'Lines count
DCount += 1
End If
'End this
'View lines count in textbox
TXTCount.Text = DCount
End Sub
