How to output a single file for each row of an excel file read in?

Question:

Tag: vb.net,excel,visual-studio-2010

How can I output a file for each row of excel data? Right now it outputs the correct number of files but has the rows of data incremented, so file 1 is correct, file 2 has row 1 and row 2, etc.

 Dim smNum As Integer = 0

        If rowct > 0 Then

            For rr As Integer = 10 To rowct
                For cc As Integer = 1 To colct
                    val = CType(r.Cells(rr, cc), Excel.Range).Value

                    If val = "" Then Exit For

                    str.Append(ht((cc - 1).ToString)).Append(",")
                    str.Append(val)

                    'assigning the sample managaer num in column 1
                    If cc = 1 Then
                        smNum = val
                        file_name = selectedFile.Substring(13, 16) & "_" & smNum & "_" & todays_date & file_count & ".csv"
                        full_path = save_file_path & file_name
                        MessageBox.Show("Sample Manager Number: " & val & full_path)
                    End If

                    If cc < colct Then
                        str.Append(",")
                    End If

                    My.Computer.FileSystem.WriteAllText(full_path, str.ToString, False)
                    lstFileOut.Items.Add(file_name)

                Next
                'str.AppendLine()
            Next

        End If

Answer:

Use StringBuilder.Clear before each row.

        For rr As Integer = 10 To rowct
            str.Clear()

            For cc As Integer = 1 To colct

I would also suggest calling My.Computer.FileSystem.WriteAllText once per row since you are writing to the file on each columns.
