Cells(i,41) represents the csv file locations that i suppose the csv folder has it which i have stored them in my spreadsheet. However, some of my csv files are not in my csv folder but still i want the programme to continue to read what i have. Unfortunately, the programme stop with an error that says file path not found at the Set o_file = fs2.OpenTextFile line. I tried to solve the issue using error resume next and on error goto 0 but this time it cause another error at the line Do While o_file.atendofstream <> True which says object variable or with object variable not set error and i tried to use error resume next again but it still wont solve it.

Sub main()

call get_file_namevcap

end sub


Private Sub get_file_namevcap() 'check csv file using readdata sub


Dim i As Integer
Dim filename As String
Dim location As String
location = Me.ComboBox2
i = 2
Do While ActiveWorkbook.Sheets("IndexPTN_STI").Cells(i, 41) <> ""
      filename = location & "" & ActiveWorkbook.Sheets("IndexPTN_STI").Cells(i, 41) 'getting csv file name eg:"Vramp_bke_2019.09.28_09.10.51.csv"
Call readdatavcap1(filename, i)

    i = i   1
