.net - Import A Tab Delimited File Into A Table : Avoiding 'End Of File' Errors?
Nov 4, 2009
I'm trying to import a tab delimited file into a table.The issue is, SOMETIMES, the file will include an awkward record that has two "null values" and causes my program to throw a "unexpected end of file".For example, each record will have 20 fields. But the last record will have only two fields (two null values), and hence, unexpected EOF.
Currently I'm using a StreamReader. I've tried counting the lines and telling bcp to stop reading before the "phantom nulls", but StreamReader gets an incorrect count of lines due to the "phantom nulls".I've tried the following code to get rid of all bogus code (code borrowed off the net). But it just replaces the fields with empty spaces (I'd like the result of no line left behind).
Public Sub RemoveBlankRowsFromCVSFile2(ByVal filepath As String)
If filepath = DBNull.Value.ToString() Or filepath.Length = 0 Then Throw New ArgumentNullException("filepath")
If (File.Exists(filepath) = False) Then Throw New FileNotFoundException("Could not find CSV file.", filepath)
[code]....
I've tried using SSIS, but it encounters the EOF unexpected error.
I am trying to import tab delimited text file to access table. The below code WORKS very well for csv file. when I try the same for tab delimited text it it importing all the fields into one column of the access table and combining the header files as one column.
I have a VB project that reads data from SQL as well as pulls data from other files into SQL. I need to import a text file into SQL table; there is no headers in the file and table in SQL is already exists. I found a code in Forum and slightly modified it, but I'm still missing something. I'm not sure how to specify that the text file is delimited with "|" character? Also - since there is no headers - not sure how to import it into correct columns? On the code below I'm getting "Insert" syntax error; on prior version of the code I was getting "field F1 doesn't exist".
I need help taking a tab-delimited text file and dumping it into a new worksheet in Excel. I get a ton of errors when I attempt to name the WorkSheet or add it to the WorkBook. I want to be able to control the name of the new worksheet.
Now i'm coding for a project in VB.net that allow user to browse to text files (i am done), after that i have to import this text file into access.
The problem i have to import a pipe delimited file (it is: #), that '#' help to distinguish each filed.
Example: my text file is: #BC2323#23241#12345. This mean that: There are 3 fileds in it: BC2323; 23241; 12345.
There is my coding for browse any text file:
Private Sub btnBrowse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBrowse.Click Dim alltext, lineoftext As String OpenFileDialog1.Filter = "Text files (*.txt)|*.TXT"
I used to just code up a module that looked like this Ref to MS Access 11.0 Obj Lib was set
Dim myaccess as New Access.Application myAccess = CreateObject("Access.Application") myAccess.Visible = false myAccess.OpenCurrentDatabase("c:\path\databaseName.mdb")
But now it seems that even with that ref included, none of these commands exist. From what I've been reading online, to do this via .net, you have to parse the file out and create a serious of SQL inserts. I'm assuming/hoping/praying that there is a more efficient way to do this...
I have to import a tab delimited file into Excel and export it back out to correct a formatting issue caused by FoxPro. I need to pad a column with 10, Zeros and that is good with this here: objxl.columns("B:B").numberformat="0000000000". However I have 2 cells in the sheet, row 1B and 2B that I want to exclude from the number format above. Because it is a date field and it writes to that same column so it pads my date. I do have a need to Pad that date field with mmddyyyy so I have to pad it 8 - zeros.
I am just trying figure out a record import program from text file into access database using Microsoft.Jet.Oledb Provider 4.0 and Vb.net. And it seems easy but my problem is different. In the text file, records are not delimited.
Format of the text file: Field Name & Size Date[Date,ShortDate]FirstName[20]LastName[20]Sex[1]Age[2]
[Code]....
Can I put delimiter programmatically while reading the text file using stream reader and later simply import the whole file in DB.
So i'm new to working with vba in access and i'm having trouble getting this code to work. What it is suppose to do is take a selected text file and read the original file into a list box. Then there is a second button that when pressed will convert the text file from a pipe delimited file into a tab delimited file and then show the changed file into a new listbox.
Option Compare Database Option Explicit Function GetFilenameFromPath(ByVal strPath As String) As String
I am having an issue with my code. When I debug, I find no errors. When I test the code, it doesn't import into the table. I have checked to make sure the file is in the proper location and that the connection string is correct to sql. Here is my code, can anyone offer some thoughts? My second question would be, once I get this to work, how do I code it to perform the same task but for 5 other files and 5 other tables? Tables are in the same db.
I am getting a complex XML sheet which I intend to upload in SQL server table. I do not know how to do it? I am using visual basic.net 2008 and sql server 2008 R2. The XML file shown below has seven days weather forecast. I do not need some of information from this file like PRECIPITAION information.
I am not sure what is the procedure to parse XML and import it in SQL table.
I want following info out of it,
1) Weather Update Date & Time (common for all seven days)
I am new to .net, I got a project in which i need to import dynamically excel file into sql table. Like user will select the excel file and the sql table, then all the columns from excel file and the fields from sql table comes on the form, then user will select which column need to go to which table colums.
I am using VB.net code and SQL server 2005.I am havng below code for sending email in my vb.net code.
Protected Sub ibtnSendInvites_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ibtnSendInvites.Click Try Dim emailList As New List(Of String) For Each curRow As GridViewRow In GridView1.Rows
[code].....
Now my problem is that some time if emailaddress is not valid or SMTP server is responding my application get hangs. I want to log my errors generated by my SMTP server in table or any log file it would be good if I can send back email to admin with the details of error occurred.
I'm using the following code to import data from a text file into an existing Access table:
Code: Imports System.Data.OleDb Public Class Carrega_CSV Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]....
The first time i ran the code, it caused no error but no records where loaded into the table. The second time it causes the OleDbException "Table 'TEMP' already exists." The text file is comma delimited and it has exactly the same number of columns of the TEMP table.
I am trying to load a text file into an Access 2007 table. I know you can read the file line by line and then create a record out of each line. i was trying to see if this could be done with an INSERT INTO rather than cyclying through all lines of text. My text file is not character delimited but rather by fixed column width. For example:[code]The data in the example has spaces for readability but in reality the data are clumped together like so [code]I cant figure out how to tell the command how the data is structured. I know you can use a schema file but there's got to be a way to do this all through code.
I am creating a shell for a FORTRAN application which reads a tab delimited text file.Because I am using Excel to manipulate data, is it possible to use the Excel Automation features to "save as" a tab delimited text file?The only method available seems to be a unicode text format, which does not work. Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?
I am trying to import a TAB (NOt comma) delimited text file into a DataGridView. The following code works fine if I have a comma separated file. All I have to do is change the FMT to "Delimited".It just does not work with FMT=TabDelimited. All columns are read into single datatable column. The text file is ANSI text and I have double checked to make sure Tabs are tabs and not spaces, even exported a sample Tab Delimited file from Excel.Can this even be done using Text Driver? [code]
I want to load a csv file (A comma delimited text file) into a datatable. I found the OdbcDataAdapter Class which looks perfect, but it says it is supported only in version 1.1 of the .NET Framework.
Is there a better way to import a csv file into a datatable? the first line has the column headers.
I am using Visual Studio 2008, using version 3.5 of the .NET framework
I've got a problem in Importing Text delimited File to access Db , I always get an error "No value given for one or more required parameters' while execution [Select Into] Statement
[LEFT] Dim svdialog As New SaveFileDialog svdialog.Filter = "Access Database Files (*.mdb)|*.mdb"
One feature of C# compiler is that namespace declaration by default follows the folder name structure in the project. By e.g. you have MyProject1MyDrawing and inside you create a class MyPoint the namespace for MyPoint will be MyProject1.MyDrawing
In VB I cant see any namespace declaration(apparently it implicitly 'inherits' the project(MyProject1) namespace). If I create a MyPoint and MyLine clases in the MyDrawing folder I need to surround each of created classes with "Namespace MyProject1.MyDrawing"..."End Namespace".
Is it possible to automatically name the namespaces like in C# by the folder name?
i want to take a comma delimited text file and then select all unique records based on one of the fields in the text file. should i read the text file into a data table or just use a data reader?
Is is possible to import or migrate .txt files to my database? Im using VB 2010 Express. Im just a newbie in Visual Basic and I need to import a text file into my system.
