Reading Space Delimited Text Database
Jan 16, 2012
I am trying to open a text delimited database using the jet.OLEDB.4.0 driver. My connection string is as shown here:
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=" & dataDir & ";
Extended Properties=""text;FMT=Delimited( )"";"
I have read that you either need to alter the registry, or to add a schema.ini file containing information about the delimiter in order to recognize the delimiter. My question is if there is any way to do this without altering the registry or adding a schema.ini file, as both of these are unfortunately not an option. The only solution I currently see is to split each row, is this the only way out.

I am having some trouble including tab and space delimiters in my multiple delimiter code (see code below). It seems I can not just add the <vbtab> and <vbCrLf> codes into my delimiters list so I tried to replace them beforehand with a Clean String Function (also see code below) but it didn't seem to work. Ultimately, I would like to add any delimited text file to my datagridview.
The code below is working fine except for tabs and spaces (including next-to-each-other separators) I am using Visual Basics Express 2008.[code...]

Basically say I have a text file with the following contents:
"Tim", "USA", "1982"
"Jane", "Germany", "1980"
"Brad", "France", "1989"
Can I have a ListBox for each field, one listbox for Names, one for countries, one for years?

I have been able to load a drop down meny with a file, but the file is comma delimited. I tried to use the split function to only read the first part of the file before the comma, but I'm getting an erroHere's what I'm doing:
Dim Arts As New IO.StreamReader(System.AppDomain.CurrentDomain.BaseDirectory & _
"Artist.txt")
Do Until Arts.EndOfStream

Is there a set function in vb.net that allows you to read a delimited file with text qualifiers? In the past I have used the split command but that does not allow you to take into account the text qualifiers.

I'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() {"#"}

How would i get a certain text inside a textbox to equal that text space to space or null to space?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Textbox1.Text.StartsWith(Textbox2.Text + " ") And Not String.IsNullOrEmpty(Textbox2.Text) Then
Textbox1.Text = Textbox1.Text.Remove(0, Textbox2.TextLength)
Textbox3.AppendText("a")
End If
Btw: after i finish this step my project will be finished!

I have an xml file with elements that look like this (abbreviated for clarity):
<post id="1" tags="tag1 tag2 tag3 tag4" />
I want to map this to the following class using Xml Deserialization, but I can't find a way to map the tags attribute to an actual List(Of String).
<Serializable()> _
<XmlRootAttribute("post")> _
Public Class Post
[Code]....
Is there any way to override the default Deserialization?

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 am working with a database that is used for managing program requirements ie text fields of varying lengths. The database program is capable of exporting data out in the form of tab and comma delimited files. I would like to see an example in vb.net 2003 of how I might be able to loop thru an entire delimited text file line by line isolating each tab delimited field to say a text box or a string variable.My ultimate goal is to be able to write this delimited data to a special spreadsheet application capable of dealing with text block sizes beyond the capability of Excel. So now I am interested in how to manipulate huge delimited text files in vb.net 03.

So I've been using VS2010 and haven't had too many problems transitioning over but I have an issue at the moment and I can't seem to find the answer...I have been using a little piece of code to insert comma delimited files to a database, which works great.Today, I received a Tab Delimited file from a client....obv I could edit, replace tabs with commas and move on but I want to know the right way to do this so I feel accomplished I've tried two ways so far1. This is the code I use for comma delimited with a slight change for the tabs -- PF refers to a class module that has the functions I use to get files and parse file paths
Dim Conn as New ADODB.RecordSet
PF.InputFile = PF.GetFile("Select LMR Demo File", "")
conn.Execute("SELECT * INTO [tmp_lmr] FROM [Text;Database=" & PF.InitLoc &

this is how i would normally import a comma delimited text file into a ms access table:
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & System.IO.Path.GetDirectoryName(Me.OpenFileDialog1.FileName) & ";HDR=NO].[" & Me.OpenFileDialog1.SafeFileName & "]"
sql.ExecuteNonQuery()
my question is, how can i do something similar for a tab delimited text file?

I'm trying to parse a text file. First I plan on extrcating each line, then extracting each field by searching for a tasb.When I use InStr to search for a (return for end of line) or (for tab) I always get a zero. But if I put in a visable letter such as a I got a 5.also I tried /r, /n and all return a zero.The file looks as follows:
ID Name
1 Patient
2 Bed
3 PatientSet
