I've setup a TextWriterTraceListener which outputs the debug messages I've written to a file.This works fine however what I am trying to do know is output the content of this file to a textbox using a streamreader object.I originaly thought it may because I did not set the text file to allow read/write access so I changed this by setting the following:[code]

I'm making a personal program (So it doesn't have to look nice or be super sleek) that is basically an alarm clock. I set the time and date, it writes it to a text document then it reads it from the text document back into another textbox that is hidden and compares it to label1.text which is my system time and date.the problem is, I have it so that I can add multiple dates in one document so when I enter one it'll do as so [code]how can I make the program read 1 line, wait for it to match the label, (I already make it display a message box) and then after that is all done, go to the next line and wait for it to match. etc etc.

I can't seem to figure out the datatype for the phone number? It displays in my listbox, but I only recieve the number 6 and the not the full listing of the phone number 604 777 1234.
I can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox
Here is my
scorelist = New ArrayList
reader1 = My.Computer.FileSystem.OpenTextFileReader(My.Application.Info.DirectoryPath & "scores.txt")

I have a txt file, that i want to read into my program. The problem is this:The textfile is a stats file for a game and looks like this:
Code:
ip:port wins username points
ip:port wins username points
ip:port wins username points
ip:port wins username points
ip:port wins username points
etc.
The main thing i want to do is sort these things out and then add to mysql database table that would have these columns:
Code:
ip authid wins username points
So what i wanna do is splitting this textfile data up and then adding everything to a mysql table.
If I do the following
FileOpen(f, Application.StartupPath & "data.txt", OpenMode.Input)
While Not EOF(f)
Input(f, t) 'read data line how do I get to keep the leading whitespace
ie in the file there is
"one"
"two"
" three"
I want to keep the space at the beginning ie t=" three" but t="three"

[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)

I'm writing a small program where i need to insert a small piece of text in an existing text-file ( .txt).

this is probably a bit tense and I'm not sure if this is possible at all. But basically, I'm trying to create a small application which contains alot of PowerShell-code which I want to run in an easy matter.
I've managed to create everything myself and it does work. But all of the PowerShell code is manually hardcoded and this gives me a huge disadvantage. What I was thinking was creating some sort of dynamic structure where I can read a couple of text files (possible a numerous amount of text files) and use these as the source for both the comboboxes and the richtextbox which provovides as the string used to run in PowerShell.
I was thinking something like this:
Combobox - "Choose cmdlet" - Use "menucode.txt" as source
Richtextbox - Use "code.txt" as source
But, the thing is, Powershell snippets need a few arguments in order for them to work. So I've got a couple of comboboxes and a few textboxes which provides as input for these arguments. And this is done manually as it is right now. So rewriting this small application should also search the textfile for some keywords and have the comboboxes and textboxes to replace those keywords. And I'm not sure how to do this.
So, would this requre a whole lot of textfiles? Or could I use one textfile and separate each PowerShell cmdlet snippets with something? Like some sort of a header?
[Code]...
Now, this snippet above lets me either use a text file as a source for each username used in the powershell snippet. Just so you know :) And I know, this is probably coded as stupidly as it gets. But it does work! :)
I have a textfile wich my app will have to read.The textfile will be like this

I'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.
