Delimited Text To Datagridview -tab And Space Delimiters
Nov 20, 2009
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...]

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.

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 just can't think of an easy way to do this. It seems easy, but I'm not just sure how to do this. I want the software to grab a random word inside the bracket "{}". The "|" is the delimiter. Here are some examples...
Input #1: {Hey|Hay|Hello} How {are|r} {you|u} doing?
Output Example #1: Hey How r you doing?
If I execute the code again, this would output...

I've been using VisualBasic 2008 Express Edition for a little while now, and I've gotten the hang of a few things like nesting and basics like that. I love learning everything I can about it, and so I'm working on a program that's got some things I'm not so familiar with involved. I'm not sure exactly what it is I'm looking for help with; as I'm sure some of you may know, there are many different ways to accomplish the same task--it's just that we don't always know the simplest solution, unfortunately. So anyhow, I'd like this program to do a couple of things... Firstly, to read in data from a text source and display it accordingly, and also to use that data in a list box and compile a new list from the original one.I've got a rather vague idea on how to do the first objective to put it nicely.I've read a little about delimiters and such, but the problem is that everywhere I look for tutorials or examples, I'm not really seeing exactly what it is I'm trying to do.Here's an example of the text I'm trying to parse/read/whatever it is:|Name of thing|some data|blah|blah blah|
In this example, I use the vertical bar character (I don't know what it's called; it's Shift + for me) to separate data in a pre-defined order. Let's say I wanted to use this for car information, I guess.[code]Like that, only many more times. What I can't figure out though, is A.) how to make VB read every line within the text file and B.) how to differentiate each of those sets of data so that I can read them into labels on the form. At this point, all I do know is that that vertical bar (this thing) is what's called the delimiter. Other than that, I'm left to pulling my hair out.

I need to be able to read common delimited text that the user enters into a text box. For example the text box would look like this:1,200,02,200,04,120,1203,200,120I need to be able to read the lines and put the data into a multi-dimension array with all the first values in column 1, all the second values in column 2, and all the thrid values in column 3.

I have data displayed in a DataGridView. The first column is a DataGridViewCheckBoxColumn, all other columns are read-only. The checkbox is not bound to data dirctly but - depending on check state - fires stored procedures. Selection mode for the DGV is FullRowSelect.Clicking on the checkbox with the mouse (CurrentCellDirtyStateChanged / CellValueChanged) works fine. Using the space bar when the first column is active also works fine.But: What can I do to change the state of the checkbox by pressing the space bar, when the "focus" is not on the first column? Right now it is a real nuisance to be required to move to the first column befor being able to check the box.

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

I've got a problem reading in a Tab-Delimited text file. There's an extra tab in one of the fields its reading it thats not a delimiter, and it's throwing off me reading the file into a table. This specific file does have quotations around that field though.
What would be the best way to take that tab out before splitting the row by vbTab?
Im reading each line in the text field like this, splitting on vbTab. X is a string array
text = x(J).Split(vbTab)

This is my first program that I'm trying to write. I have been trying to make an application to run a date filtered query against a SQL server and output the results into a txt file that I define. I believe that my code is close for getting the data. I cannot figure out how to actually write the data into a text file. I am trying to use the datareader and streamwriter, but I am not sure what to put in the streamwriter.Write() function to actually get it to past the lines in the text file.

After some thinking, I think I figured out how to read delimited text. I was just curious as to whether it'd be better to use StreamReader.ReadLine or File.ReadAllLine or if it matters at all? I'm assuming the ReadLine method would be better if I'm working with a larger file since ReadAllLine would store the entire thing in memory? Here's my code - I'm reading from a text file and displaying into a listview.
File.ReadAllLines
Dim lines() As String
Dim parts() As String
lines = File.ReadAllLines("C:lah.txt")
For Each line As String In lines
parts = line.Split("|")

I previously asked a question about my meeting planner app, and how to delete a specific entry in the array. Someone had the interesting suggestion of using a ArrayList, instead of a normal array. I am attempting to learn ArrayList, but to no good result. I can't even get the ToString method to work correctly to write what I want it to into a text file.[code]...
My plan is to have each of those three fields to have their own entry in the ArrayList, but when it is saved to text file, those three fields are comma delimited to a line for each appointment. Of course when the text is loaded, it will have to be converted back. Can anyone point me in the right direction or have any other method of going about this with the ArrayList?

what would be the easiest way to open a comma delimited text file - each field is surrounded by quotes - and then analyze this file to find the record with the most fields being used? right now i bring the file into and access db then loop through each record to see if there is any data.

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 having a problem where instead of reading a text file from the location string, I changed it to read the text file from the resource location and it breaks my program. I've also used the insert snippet method to get most of this code, so it is safe to say I don't know what is going on. [code]

I have a text file with for example this data in it :
"19 Mar 2010","6:00","16:00","10","1","9","6.61","59.49"
"20 Mar 2010","9:45","19:15","10","1","9","6.61","69.89"
"21 Mar 2010","9:00","17:00","8","1","8","6.61","99.32"
I used " , " to delimit individual pieces of data and " " to denote end of line.I'd like to be able to split the files into lines and assign each line to an array then split each of those array strings into the comma " , " delimited data and feed each piece of data into another array ready for writing to a datagridview.
I've spent a while trying to get Split() to work but I get errors regarding converting strings to one-dimensional arrays Also the Split() method asks for a "ParamArray" but I haven't been able to find examples of other people providing them on the net any idea what those are about?
