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.

Reading From TextFile And Populating Textboxes

May 8, 2012

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

Reading Strings In Textfile And Adding Them In A Listbox?

Jan 6, 2012

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")

Visual Basic 2008: Reading From Textfile Into Array And Then Presented In Listbox?

Jan 7, 2012

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)

File I/O And Registry :: Line By Line TextFile Reading?

Mar 5, 2009

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

.Net - Writing To Textfile From A Textbox?

Nov 7, 2010

just another little problem here! Trying to write a quiz for a college portfolio and having trouble with writing to a .txt textfile. On one form(form4.vb), I have a listbox that picks up the information held within a notepad textfile called "usernames" which contains names of quiz users. When written in manually to this textfile, my listbox picks it up fine, however, on a different form(form3.vb), I have a textbox where a user inputs their name, this is supposed to go to the "usernames.txt" textfile to be picked up by the listbox on the other form but instead, it does not write anything at all and if there is already text on this textfile, it wipes it all out.I also have to use the application.startup path instead of the usual C:my documentents etc so i would have to begin with something like this: (Note: code is a little mixed up due to messing around with different variations but this is just a example)
