Forms Reading From A Textfile
Dec 13, 2010
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'm having trouble reading in the file and populating the textboxes accordingly. After loading the file (I think that is) nothing is being populated in any of the textboxes listed below. Basically I'm not sure if the file is being read or not.
If OpenFileDialog2.ShowDialog() = DialogResult.OK Then
If My.Computer.FileSystem.FileExists("path_to_file") Then
Dim ioFile As New System.IO.StreamReader("path_to_file" + "filename")
TextBox1.Text = ioFile.ReadLine() 'Adds the first line
TextBox2.Text = ioFile.ReadLine() 'Adds the second line
TextBox3.Text = ioFile.ReadLine() 'Adds the third line
TextBox4.Text = ioFile.ReadLine() 'Adds the fourth line
TextBox5.Text = ioFile.ReadLine() 'Adds the fifth line
End If
End If

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'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 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.

I've got the following txt file:
[code]...
Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[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)

Ok i am making a game (based on windows95)....i have it going good so far.I have it so you can open notepad (this is in a panel and its not the real system notepad)You can click save document and it saves the text it in a hidden textbox with a random filename (defined by user) and it saves it in a listveiw (windows explorer type thing).The idea is i want it to be so that if you double click the listveiw item it will open the textfile (text stored in a hidden textbox) Heres my code which is attempting to do this but i just can't think how to link them.

I'm making a program which has 7 textboxes. I intend the program to be used for classes in school, so the text would be like 2D Art, Geology etc... whatever your classes are. I have figured out how to use the streamwriter to take the text in the textboxes and write them to a .txt file however, my issue is with loading the text from the .txt file back into the textboxes. I did figure out how to write it so that all the text in the .txt file is loaded back into textbox1 but I have 7 textboxes... Here's the coding for the Load button:
Private Sub Button46_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button46.Click
Dim MainWindowLog As String = "V:Users(O.o)~(--_--)~(o.O)DocumentsVisual Studio

I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???
Dim pathdir As String = "C:workingdir est.txt"
If System.IO.File.Exists(pathdir) = True Then
Dim objWriter As New StreamWriter(pathdir)

I have a basic math test program, and 2 forms to allow the user to choose which function to test on.
The first form has a list of radio buttons with the 4 basic math functions and a button to load the next form.The second form contains this code on Load..
[Code]...
frmOptions has 4 radio buttons, addition is default chosen.After selecting one, the user clicks a button to open frmTest.The above code runs upon first load to change a label to reflect what was chosen on frmOption above.
On step 3, the label on frmTest that is supposed to be changed based on the Checked radio button from frmOption never changes. It doesn't even change on the first load of the form, so I think something is wrong with the Checked property of the radio buttons.

I am about to develop a software (VB .Net) that generates and reads barcodes. The backend db is sql server. 1. I have a major id and sub ids. For example I have major ID A, and subgroups A0, A1, An. Also I could have more detailed subgroups like A01, A02 and so on. I need to generate and print these barcodes from my VB application. 2. The handheld scanner is used to read the generated barcodes and pull their data and show them on the screen.
