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.
View 3 RepliesI'm busy with an applicaton which reads space delimited log files ranging from 5mb to 1gb+ in size, then stores this information to a MySQL database for later use when printing reports based upon the information contained in the files. The methods I've tried / found work but are very slow.
or is there a better way to handle very large text files?
I've tried using textfieldparser as follows:
Using parser As New TextFieldParser("C:logfiles estfile.txt")
parser.TextFieldType = FieldType.Delimited
parser.CommentTokens = New String() {"#"}

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.

View 8 RepliesI 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".

View 4 RepliesWhat i have going on, is i have a MySQL connector as a resource on my application, and im basically trying to connect to my MySQL server, to either a) register a new account, or b) check that the account exists and they are premium, and login, Now what i have run into problems with is: My MySQL Database Name has a _ in it which VB is not allowing for some strange reason.
The code i am using is below
Imports MySql.Data.MySqlClient
Public Class Form1
Function UpdateRecord(ByVal query As String) As Integer

How i can allow the _ into the application, because the only databases that don't have a _ in the user or dbname are a) Paid ones which i DO NOT have the money for or self hosted ones, i cannot leave my computer on 24/7

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.
