.net - Writing A .txt File, Without A Extra Line?
Aug 5, 2011
Public Sub WriteTextFile(ByVal SourceToWrite As String, ByVal LocationToWrite As String)
Dim file As System.IO.StreamWriter
IO.File.Delete(LocationToWrite)
[Code].....
This is a module I made to write to a .txt file. Every time it adds a new line with null value. wouldn't really bother me but it adds but then something that only suppose to have like 3 lines in it ends up with 5000 over time, anyone know how to not add that extra line while writing file?

I have an array called lines() which is basically an array indicating which lines to read from a file. for example lines(1) = 0 means 'read the first line from the file', lines(2) = 4 means 'read the 5th line from the file' (counting from 0 not 1) The program first reads the file (which has a lot of random lines) so it can identify which lines match my criteria. The way I store the line positions is this:
For i = 0 to noOfLines -1 'total num of lines in file
If count = match Then 'this is my match criteria
lines(x) = i 'store the line in the array

I am having problems with opening a file and writing in a new line some data.Instead of writing the data in a new line,it replaces the data in the first line of the file with the new data.The function is this:
Code:
Private Sub cmdAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAdd.Click
ListBox1.Items.Add(txtServerName.Text)

I am writing each line to a text file:
Dim objWriter As New System.IO.StreamWriter(filename)
For Each x In tofile
objWriter.WriteLine(x)
Next
objWriter.Close()
Which works perfectly the only problem is is that when its finished it writes a blank line on the end of the text file which I don't want.

I am attempting to write data to a text file from a form.
My code is as follows:
x.Write(TextBox1.Text)
x.Write(TextBox2.Text)
x.Write(TextBox3.Text)
x.Write(Textbox4.Text)
x.WriteLine()
x.Close()
I have x.writeline() which writes a new line to the text file. However when I add all four textbox values they appear as follows:
Textbox1Textbox2Textbox3Textbox4
But I want it to look like:
Textbox1 Textbox2 Textbox3 Textbox4

I am making a vb.net app and I need to know how to overight onto a specific line in a text file. For example:[code]Now, I want to completely overight the "B" to an "A" and the line I need to write on is "2" also, my application will produce dynamic text files as well so I wont always be able to know what line exactly to overight. So my question is, how do I write to a line when I know what line it is and how do I search for a specific line and overight that.

I have the same problem that Niphoet had in this thread: vb .net overwrite a specific line in a text file
I am trying to implement the code that Axarydax showed in C# that I am trying to translate to use into vb.net. My problem is that the code will make my new text file but will not write any of the lines from the other text file to it and just leaves it blank. I think my problem is with the while loop statement but I am not sure.

I've got my self in to a pickle here.I'm trying to do something I used to do in basic? At-least I think you can do this in Basic, you know Qbasic,What I'm trying to do is put 4-8 strings on to one line separated by a comma.Example might be:
writer.writeline (bob1, bob2, bob3, bob4) Out put might look like Test, Test2, Test3, Test4
I'm tried looking in to formatting of writeline/write, but I didn't get any where with it.
Also if this is possible- I would like to be able to read it just like :
reader.readline (Rbob1, Rbob2, Rbob3, Rbob4) If anyone cold just point me in the right direction, I'm sure I can figure it out - If not... Well I will ask another question.

the first is validating numeric input in a textbox to make sure it's got two decimal places. I think this should be really simple, but I'm totally missing it.The second is adding an extra summary line to a listview. I have it working with all the data required, but I need to add an extra line at the end showing some totals. How do I do this?

what im trying to do and what i have done so far is probably a little backwards not sure sure how to id it any other way.when the user generates an error because a particular file doenst exist ive got my dialoge box to generate an .txt file for each file it errors on, so that the administrator can check and update missing files as an when - shouldnt be many files missing in the first place, should just be new product ranges or item just launched.what im stuck on is:
1. is there a better way
2. how do i open a .txt file and add the extra lines to it, so i re use the file but keeping the previous data.

I have lines like above in my text file. I have write all this value in another text file by adding the title. In my original file's line I must check whether the line contain any MIL value if not, I must write first T1 the below T1 I must write all the line which not contain MIL value until I reach a line which Contain MIL value. If the line contain 39MIL the I must write first T5 then followed by all the line which contain 39MIL until it reach the line which contain another MIL value. Let say 50MIL. the I must write T7 then followed by all the line which contain 50MIL. I sort my original file already. so the original file will start from the line which dont have MIL to 39MIL,50MIL,75MIL and 100MIL.
My output file will look like this:
T1

I am coming across a lot of odd and annoying problems in this program and have almost had enough lol.
I cannot figure this one out for the life of me. I have used streamwriter a hell of alot of times and never once experienced this. But basically I have a string array and I need to write the entire array to a text file with a new line for each array item. So I have gone ahead and done this:
[Code]...
However the outcome is the text file only contains 1 line and that line is the last item in the array yet I know the array has got at least 50 items in it.

How would i go about reading a file Line by Line that within that line The values are delimited by " Example of the data:
"bob" "cat" "1243"
"steve" dog" "6789"
I've started this with this code but not sure how to go about the next stage:
Using MyReader As New _
Microsoft.VisualBasic.FileIO.TextFieldParser(My.Application.Info.DirectoryPath & "Records28112011.jd")
MyReader.TextFieldType = FileIO.FieldType.Delimited

I have been having problems with creating a download list of files for a downloader and was getting unexplained "File Does Not Exist" returns. My .avi files were returning found but but .exe and .txt files were getting the not exists.
I have now found by pulling in the whole directory and examining the file contents that my .exe files are showing ".exe.exe". My .txt files are showing ".txt.rtf". Wow, browsing the file directory in Server 2008 only shows a single extension. I don't see an option to display the extension as a column, just the "type". My directory looks like this:
Name Type
File1.exe Application
File2.txt Rich Text Document
File3.avi AVI File
I had renamed some of these files, maybe I just cannot rename files. I will try using originals ans see if I am ok. Maybe I need to rename the offending files without the displayed extensions. Is this just something weird with the server browser?

I've been asked to re-write an application that was written sometime ago by another programmer. This application reads data from a database table, massages it, and then writes out the results to a text file that is later shipped off to another company. When I run my new application, it generates a file that, according to the byte count, is twice the size of the file output from the old application. However, to look at the two files with note-pad they look identical. I found that by using 'Ultra-edit' that the new records have a low-value byte hex '00' between each real character.

I am writing a program that will read and write to a file using the My.Computer.Filesystem namespace, and when I append my data file with the code shown below under SaveFile subroutine, it sometimes places extra ControlChars.Newline at the end of the appended text. Sometimes it places one extra newline, and sometimes it adds 3-6 newlines. I have tried everything I can think of to make it add just one newline at the end of each append, as I will be using the newline char to flag each entry on retrieval. I am working out some algorithms in this project to use in a project that will keep track of data in a file using csv format(just practicing saving/retrieving data from a file). The extra newline characters that are added will become a problem when I start to sort the data to display. my xSaveButton click event:
Private Sub xSaveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xSaveButton.Click
Dim boolAppendData As Boolean
If My.Computer.FileSystem.FileExists("myData.dat") = True Then

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.
