Import from text file into database via vb.net

Am at home at the moment so cant post exaxt code.  But use the code below to loop through the excel file.  Just stop/start  at the line you want using the count and indexof for the "ABI" bit.

    Public Sub ReadFile(ByVal fileName As String)
            Using reader As New TextFieldParser(fileName)
            reader.TextFieldType = FieldType.Delimited
 
            ' Set the delimiters for comma separated text
            reader.Delimiters = New String() {","}
 
            Dim currentRow As String()
 
            While Not reader.EndOfData
                Try
                    currentRow = reader.ReadFields()
                End Try
            End While
        End Using
 
    End Sub

VDA,

Hmmm. First of all the file I'm trying to get the data from is not a csv file, it is a text file with blank spaces and  other various crap that get in the way of just copying it into the access database.

Thanks,

Can you post the file

VDA,

I did!  The file to import from (FBIN.txt  and the access DB (weather.mdb).

Thanks,
Cheese

Open the text file in Excel then save it as a CSV.  

Give me a moment and Ill try it this end and send you some code.

VDA,

Hmmm.  Please notice that I only want the data from that text file starting with the row that starts with ABI.  Of course, all of this will be seamless to the user, the downloading of the information from a website, the parsing to a text file, then importing into the database.  

Thanks,
Cheese

Try This after you open in Excel and save as CSV.  Works for me.

 Public Sub ReadFile()
        Using reader As New TextFieldParser("c:\FBIN.csv")
            reader.TextFieldType = FieldType.Delimited
 
            ' Set the delimiters for comma separated text
            reader.Delimiters = New String() {","}
 
            Dim currentRow As String()
            Dim Windsaloft As String = ""
            Dim StationID As String = ""
            While Not reader.EndOfData
                If reader.LineNumber > 7 Then
 
                    currentRow = reader.ReadFields()
 
                    'Get the Station ID
                    StationID = "K" & currentRow(0).ToString()
 
                    Windsaloft = currentRow(1).ToString()
                    Windsaloft += currentRow(2).ToString()
                    Windsaloft += currentRow(3).ToString()
                    Windsaloft += currentRow(4).ToString()
                    Windsaloft += currentRow(5).ToString()
                    Windsaloft += currentRow(6).ToString()
                    Windsaloft += currentRow(7).ToString()
                    Windsaloft += currentRow(8).ToString()
 
                    '''''''''''''''''''''''''''''''''''''''''''''
                    'Add you insert to databse code here
                    '''''''''''''''''''''''''''''''''''''''''''''
                End If
                currentRow = reader.ReadFields()
            End While
        End Using
 
    End Sub

VDA,

Hmmmm.  Is there a way convert or save the text file to a csv in code?  This has to be seamless to the user.  Also, couldn't I loop through the array instead of the individual statements:

Windaloft += currentRow(x).ToString()

Thanks,
Cheese

Change the Delimiter to a space then read in the original text file.


 reader.Delimiters = New String() {" "}

VDA,

I greatly appreciate the help.  Are you aware of the haphazard spacing (blank spaces) in the text file?  Do you think the blank spaces are going to cause a problem?

Thanks

VDA,

I am using Visual Studio 2008 and I do not see the TextFieldParser method in intellisense.  I am using the StreamReader method to do this.  Could you incorporate the StreamReader method somehow?  Here is a routine from a previous assignment that populates the same database from a csv file with the data that is already present in the access DB.  I need to just add the windsaloft data.

Private Sub btnLoadDB_Click(ByVal sender As System.Object, _
         ByVal e As System.EventArgs) Handles btnLoadDB.Click

      Dim stationFile As New StreamReader(_strCsvPath) ' read csv file
      Dim stationRecord As String ' record variable
      Dim arrayFields() As String ' array variable
      Dim strIdent As String ' string ID variable

      ' Constructor for dbUpdt class
      Dim database As New dbUpdt(_strSource)

      ' clear the listbox
      lstStations.Items.Clear()

      ' loop through the database and load the listbox
      Do Until stationFile.EndOfStream
         stationRecord = stationFile.ReadLine
         arrayFields = Split(stationRecord, ",")

         strIdent = arrayFields(0)

         database.AddRecord("stations", "stationID", strIdent)

         database.setDBField("stations", "stationID", strIdent, _
            "stationName", arrayFields(1))

         database.setDBField("stations", "stationID", strIdent, _
            "state", arrayFields(2))

         lstStations.Items.Add(arrayFields(1))

      Loop

      ' close the database
      database.close()
   End Sub ' btnLoadDB_Click

Thanks,
Cheese

VDA,

Okay, this is what I was looking for:

Private Sub btnUpdateDatabase_Click(ByVal sender As System.Object, _
      ByVal e As System.EventArgs) Handles btnUpdateDatabase.Click

      Dim database As New dbUpdt(_strSource)

      ' set the status message
      StatusMsg.Text = "Updating the Database"

      ' Using reader As New Microsoft.VisualBasic.FileIO.TextFieldParser("c:\data\FBIN.txt")
      Dim reader As New StreamReader("c:\data\FBIN.txt")


      Dim currentRow As String()
      Dim currentLine As String
      Dim Windsaloft As String = ""
      Dim StationID As String = ""
      Dim StationIDOriginal As String = ""
      Dim lineNumber As Integer = 0


      While Not reader.EndOfStream
         lineNumber += 1

         currentLine = reader.ReadLine
         currentRow = Split(currentLine, " ")

         If lineNumber > 8 Then
            Windsaloft = ""
            Try
               StationID = "K" & currentRow(0).ToString()
               StationIDOriginal = currentRow(0).ToString()
               For i As Integer = 1 To currentRow.Length - 1
                  Windsaloft += " " & currentRow(i).ToString().Trim()
               Next
            Catch ex As Exception
               MsgBox(ex.ToString())
            End Try

            database.setDBField("stations", "stationID", StationID, "Windsaloft", Windsaloft)

         End If
      End While

      reader.Close()

      database.close()

      btnPopulateComboBoxes.Enabled = True

      StatusMsg.Text = "Ready"

   End Sub ' btnUpdateDatabase_Click

You definitely steered me down the right path.

Thanks,
