Adding A Line Of Text?
Jan 28, 2009
i would like to use a "template" text file that would be stored in the app path in a "templates" folder the user then picks what template they want and enters the few lines of text they need to change in textbox1 and texbox2 on the main form..
Dim filename As String = "C:\Documents and Settings\TADS\Desktop\kev\tads.veh"
File.Open(filename, FileMode.Append)
File.ReadAllLines(filename)
[Code].....
but somewhere along the lines i have lost myself and i havn't set the content (the string array to write the file) im not sure how to go from here..

I want to modify a text file. It has a lot of lines of text in it. I want to add a line after a specific line (in the middle on other lines) and write strings there.
The code i have, writes to a specific line but it also overwrites the text on that line:

I have a line of data that represent a data import. When the import is done, I would like to keep that exsisiting line, and add another line for the next import. So I have a display of mulitiple lines, showing multiple Imports.So this is one I have for the first section, it loops through the data so you see the rows incrementing
TextBox1.Text = clsDatRow.iFirstVal.ToString + " ROWS:" + iCountRows.ToString + " " + Date.Now.ToString
TextBox1.Refresh()
Now, I can I keep the line of data, and add a new line so for the next import, it does the same thing. It ried vbnewline, but it just clears that line, it doesn't move down to a next line.

Is it possible that when a new line (anywhere in a richtextbox) is added/deleted, then a line is also added/deleted in another richtextbox?

I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

I have a couple of VB6 programs which work 100%, however not under W7, so I need to upgrade them to Visual studio 2008 pro which I own a copy of.The VB6 software used to open a file, read in a line of data and process it then save it in a new file, before going on to the next line input.I need to convert this process to VS2008 pro and can't get my head around it..... getting old you see.I also have a few other needs to do with file handling, but I may be able to sort them myself if I get a start with the above problem....

I have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.

Basically, I'm creating an application which takes a list of words in .txt format, such like this:
Abc
Def
Ghi
Jkl
mno
What I want to be able to do is modify the words, one by one, so that I end with
Abc1
Def1
Ghi1
Jkl1
mno1
or whatever the user wants.
I created this app in C++ to get the logic, since I am more confident with that

I just joined this forum as I've been looking for a nice and serious VB forum for a long time
I'm having troubles making a program to search a text file line by line for a specific string.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim objReader As New System.IO.StreamReader("C: est.txt")
[Code]...
as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.
now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost
for a "Readnextline" command or something like that?

Ok, I saw this code on the net
Dim sFileName As String
Dim srFileReader As System.IO.StreamReader
Dim sInputLine As String
sFileName = "D:UsersArbenDesktopSerieA.txt"
srFileReader = System.IO.File.OpenText(sFileName)
[Code]...
under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file

I currently have a line of text in my listview that is too long for the current width of my
listview, without increasing the width of my listview, is there a way to add a newline within the
listview line item so that it's 2 or 3 lines long so there's no need to have the user scroll to see
the text?

I have a dataset that is being populated from a text file.
OrderNumber,Name,Model,Cost
123,john doe,product1,20.99
123,john doe,product2,10.75
There can be multiple of the same order number. In the dataset, I want to have a column "line number" and I want to put in it the value of the linenumber (in this case 1 and 2) per order. In sql , I was able to accomplish this by inserting rownumber() and grouping by order number. Can this be done in .net?

I made the labels red so you can see them. I used a picture of a little mug as bullet, aligned top-left. The label text normaly begins at the far left of the label, but with a bit of coding I solved that problem. I did not want to add extra spaces
to the text directly for keeping the data base small. The problem however is when the label has 2 or more lines of text the text don't line up nicely with the top line, once again I no not want to save the extra spaces to the data base.
Here is the picture and the code used.
CheckLabel.DataBindings.Add("text", Hoof_GeregteBindingSource, ("Inhoud" & (Inhoud_Label_Counter).ToString))
Dim MyVar As String = CheckLabel.Text
MyVar = MyVar.Substring(MyVar.IndexOf("#") + 1)
Select Case CheckLabel.Text.Substring(0, 1)

In a Windows Form project (using VB Express 10), is there a way to use a second command line arg (first one is in a module1 for start-up that checks another command line, and if correct, runs app)? This second command line would be used to close the open app (including all forms)? (I already have set up a Module1 to recieve a command line to run the app. This would be a second command to close the running app.)
I am opening the WF app using another app (created in a different software) that can pass command lines. So, if in that other app, I send "close" as a command line arg, how do I set up the WF app to receive this specific "close" command and perform Application.Exit()?
As a beginner using VB, not sure where it would go, how to declare, etc.
