As you can see, they have these annoying spaces. What I want to do:
1. Get rid of the spaces, But keep the space between the IP and the Port.
2. After the spaces that are bad are gone, I want the program to output each single IP AND port To its own text Box. It doesn't matter is the textbox of the IP and Port are seperated, It can just be one textbox with the IP and port, with a space between them. Thats about it!! I have the GUI done, and the rest of the programming, all I need now is this.
Reformat without spaces > output each seperate line of text to a seperate textbox > TYTYTYTY
Is there a way for VB to send a command to the command prompt? Say, I wanted it to open a CMD box and send ipconfig into that box, what would that be?

I am trying to read in a TextBox line by line and take the first 7 characters of each line and output everything in another TextBox.This is what I have so far.
Dim line, lines() As String
lines = TextBox1.Text.Split(Environment.NewLine)
Dim i As Integer = 0

I'm trying to do a project which involves reading the text from a number of textboxes and putting it into a string.I'm just wondering if there's an easier way to it other than:
CreateString += TextBox1.Text + TextBox2.Text + TextBox3.Text... (etc)
I have thought about creating a For Next loop which would go something like:
For i As Integer = 0 To intNoTextBoxes
CreateString += TextBox(i).Text
Next
But this really doesn't work. I also found something saying that something similar to this would work:
For i As Integer = 0 To intNoTextBoxes
CreateString += Me.Controls.Item("TextBox" & i.ToString).Text
Next
But that didn't work either.
Using vb.net/asp.net 2005
I am trying to create a string message for an email that I am sending out from my asp.net page like so:
For Each dr In dtDataTable.Rows
strMessage = strMessage & vbCrLf & vbCrLf & Environment.NewLine & dr.Item("UserName") & Environment.NewLine
Next
so I am looping through a datatable and getting each name from each row, that is working well but when I get the email it appears in my inbox with all the names mashed together, you see I am trying both vbcrlf and newline but looks like neither is working
i need the app to preview the line in textbox in timeintervalof 1 s (can be change)nd when it will reach to the end it close the text file and andreread it after let say 1 m ..

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.

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 must use streamreader to read text file line by line into array.

the following code was to be entered to read each line of the file "line by line" It did not work for me as instructed and I am trying to understand why?

i am doing program to read text file and fill the data to multi array , in my code i tried to read the first line of text file to array (here i used class) to save this data on it, because i will use it to read the another lines , files have the following format (all numbers are integers, all intra-line separators are spaces): First line: Number of events, number of rooms, number of features, number of students after the first line as u see we have 3 line have 10 which mean the One line for each room:Roomsize and after that the line which start from zeros and ones it format as:-

I need to read a specific part from my text file to and show it on a text boxI have I have three text boxes.and the text file is written like this
View 10 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.
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'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.
Imports System.IO
Dim I as Integer
Dim LineText as String

What I have stored in my file is values related to an account. (Just testing, not going to be used commercially). What I need is to draw the values for the username and password, by going through each new line, but .peek() doesn't seem to work for me.

public string CheckAccount(string username, string password) {

string filename = "H:\AccountInfo.txt";
string s;
string result = "";

My code doesn't read from the 2nd line onwards, it just hangs.
I have been learning VB for about 3 months now at college and decided to enhance my skills by making my own project at home. My project is basically a game where you have to guess if the next number will be higher or lower than the previous version and you can place bets on it. I have done all of this ok but I wanted to create a high score system so that you could save your score.I can manage to write out to a text file ok so that it looks like this
Highscores
Name
Score
[code]....
etc. But I am not sure on how to read in a specific line. So for example I want lblHighscore1.text to equal line 3 of the text document (as vb counts the first line as 0) So far all I have is this;
Dim objReader As IO.StreamReader = New IO.StreamReader("C:UsersKarlDesktopHighScore.t xt")
lblHighscore1.Text = (objReader.ReadLine)
I've been trying to fix this problem for days, but I haven't been able to successfully apply any of the code that I've found to my project the way it is right now. Maybe I'll need to change the way it reads the file altogether.
Anyway, I'm trying to read through a text file line by line, reading each line into its own string.
