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]
View 2 RepliesI have just recently been using VB 2010 after using VB5. I have noticed a lot of changes. The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?
View 1 Repliesi created a text file with some employee data in vb 2005, on my form i i have a bunch of textboxes and a combobox. i can load the employee numbers manually into the combobox but want the employee details to show in the textboxes when selecting the different employee numbers. i declared a structure with the various fields and a reader to read the text file. here is where i am stuck. my code thus far:

I want to read the text file and check whether its contain the specific string or not at the end of the text file. If it doesn't contain the specific string, I want to append the text file to write the specific string.. Can I use this code? But its not working..What is the problem actually?

Im trying to open media player (full screen) and play a movie. When i create the file path like so: Dim MoviePathVTS As String = String.Concat("""" + tempMoviePath, " \VIDEO_TS\VTS_01_1.VOB" + """")
It wont play the file but if i do it like this: Dim video1 = """F:\Movies\DvD\Angels and Deamons\VIDEO_TS\VTS_01_1.VOB"""
It plays fine? the file paths are the same including the extra "" but it just refuses to play. I need the top one because i have many movies in a treeview.
Heres my code
Private Sub watchNow_Click(ByVal sender As Object, ByVal e As EventArgs)
'get the position of the selected node

I am working on a project in VB 2008 and need it to do this:Read first line from text file (using Openfile)Enter line into textbox on formDo some other codeThen Read second linefrom text fileEnter line into same text boxand loop until we have gone through text fileI am not sure how to read line by line from text file then enter it in textbox. I can open the Openfile and get the filename and everything, but I just am not sure how to read from it or enter that line into the textbox.Here is what I have, its not much but its a start:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.
I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.
I've seen other examples, where it works, but you must open it a different way -- with a file number.

Dim I as Integer
Dim LineText as String

View 2 RepliesI've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
I'm trying to read a text file that contains info like this:
ACX-101-011 , J2168
BTXR-130A-013, D6733
AJ4-233-614, T8211
I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.
Dim TempFile As String
TempFile = "temp.txt"
Dim sw As StreamWriter

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
I made a media player that has a list box to select the file to play but it displays the file path but I want the filename and length.The code is:

Here is my code for splitting "," from the text file. But the problem is I don't know how to include looping in the code to make the code read the whole text file. when I run this code, it's only read the first line of the text file.
Dim sr As StreamReader = New StreamReader("C:\drill.txt")
Dim data As String()
data = sr.ReadLine().Split(",")
[Code].....
i have this simple code from a vb.net project:
Using sr As New StreamReader(NewSwitch.ActFolder & NewSwitch.ActSShowName)
worker.ReportProgress(LoadSwitchProgressType.Normal, "Loading Active SupportShow, size " & NewSwitch.ActSShowSize & "...")
NewSwitch.ActSShowData = sr.ReadToEnd
End Using
Obviously it reads a file - a 20M text file to be exact. Now if this 20M file is on my PC, it reads in about a second. If i open this same file in a text editor, such as Conext, its about the same.However, if this 20m File is on a network location, the Context text editor loads the file in about 1 min 40 seconds. I would have expected similar times with my vb.net code, but it took 7 minutes 45 seconds.I have no idea what the text editor uses to read a file, but i figure i must be able to get similar time in vb.net somehow.

I am trying to create a program that will refresh a *.log file within the program itself (in a RichTextBox), but while the actual application that is writing to that *.log file is open and is utilizing that file as well.
I have tried multiple things with StreamReader, but I can't seem to get anywhere...
Simply, I want to be able to read a *.log file in my Visual Basic 2010 program, but while the actual application that is writing to it is running itself.
How can I do this, as I keep getting the error that another process is utilizing the *.log/text document?
My problem is I have very large text files (approx 2GBs+).They have records in them based in one per line.Each line is not the same length and the data can be different lengths all the time.I am currently reading the file line by line, then splitting the data by common characters in the records. To process the full file it currently takes 3hours. This is way too slow for its purpose.
