Loading File To Edit Text?
Aug 1, 2009
I am new here and just started visual basic 2008. I want to load a BIG file to edit the text. It is 24MB So whenever I load it in the richtextbox it shows : 7@
:/ Regular text files load fine.
Here is the
CommonDialog1Open.Filter = ("EXE [*.exe*]|*.exe|All Files [*.*]|*.*")
CommonDialog1Open.ShowDialog()
rt1.Text = (My.Computer.FileSystem.ReadAllText(CommonDialog1Open.FileName))
I know I am trying to load .exe! It will load if I save it through the program but will only show 7@.

I have is my columns are separated by spaces but these spaces can vary between 1 space and 20 spaces. So would it be possible to replace all spaces with one space? This will mean that each column is seperated by one space and I can then start working on my next bit of coding with deleting columns.

I have two text files. The fields in each text file are separated by a space (" "). Some of the fields in column 1 of file 1 match the fields in column 1 of file 2. However the third column in file 2 is a numeric field. What I wish to do is check every field in file1 against the field in file 2, and if the number is 1 then remove the row from file 2, if the number is > 1, then subtract one from it.
I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1"))
Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2"))
Dim values As New Dictionary(Of String, Integer)()

I'm having a problem with loading two text boxes from a saved text file. I've built a log in form that saves the user-name and password on separate lines in a text file.I have a save button and a load button. My problem is that I'm new to Visual Basics and I can't figure out how to get the two lines from the file to load into their separate boxes on the form.The code that I have loads both lines from the text file into the User Name Box.Oh the username is on the first line in the text file, and the password is on the second line of the text file. Could someone please help! My Loading code is:
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click
If File.Exists("Login Config.txt") Then
Dim ioFile As New StreamReader("Login Config.txt")
Dim ioLine As String ' Going to hold one line at a time

I am trying to create a program which reads data from a text file and insert the data in to a SQL 2005 table, but unfortunately it only reads the first line and insert correctly but not the rest of the lines on the text file
The text file looks like this
Test.txt
John, Doe, 40, 12/04/1968
Micke, Gulm, 39, 07/08/1970
[Code].....
sort out this issue as I need read the entire text file which in reality will be about 5000-10000 lines and insert them in to the SQL DB line by line.

Ok so i have a uni assignment to delete lines of text out of a text file, so far i have figured out how to search the text file for specific bits of text, i,e name of user, ive also used a loop to find out what line in the text file the specific line exists as...my
code so far is
Dim line As String
Dim Input As StreamReader
[code]....
the selected policy is what im tryin to use to write over the line of texts that already exists however i think that maybe instead of deleteting what exists it will just move it down a line and make a blank line

I picked the idea to make a little agenda for my own use and my plan was to edit a txt file using the RichTextBox. I want to use a DateTimePicker too, so that I can load a specific text file for the date chosen so that I can edit it. Does anyone have an idea how I can use the DateTimePicker to create and load certain txt files related to the same date?

So i have a text file that is created in the program which can be loaded back into the program(game save)
Whatever is in the text file "stats" should be listed in listbox1 in the same order it is in the text file. The same with "items" in listbox2. And then "quests" will be in listbox3.
The problem is when i load it instead of what is in the text file it says...
note that box3 is correct that it has nothing in it.

Getting a vibe that my VB is cursed. All I want to do is load a textfile and have the text appear in TextBox1 But no. I have looked at 3 different tutorials and I have tried copying their code word to word but still!
Public Class Form1
Private Sub ImportToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ImportToolStripMenuItem.Click
[CODE]...
And it gives me the following errors:
Error1Character is not valid.C:\Users\Saurabh Sharma\AppData\Local\Temporary Projects\WindowsApplication1\Form1.vb1067WindowsApplication1
Error2'daText' is not declared. It may be inaccessible due to its protection

My program requires that a picturebox change its image during run time. I've used:
PictureBox1.ImageLocation = [file location]
PictureBox1.Image = Image.FileFrom([file location])
Both work fine, usually.

i have code for loading a text file (comma separated) into my DGV:
If Not DataGridView1.LoadTextFile(TextBox1.Text, ErrorList) Then
Dim sb As New System.Text.StringBuilder
sb.AppendLine("Failed to load text file, see error messages below.")
[Code]....
I'm wondering...is it possible to run this code if the user was to drag and drop the text file onto the datagridview, rather than having to navigate via buttons etc...it'd make it a much nicer method!

Trying to write an app to load a Text file and then search for substrings that contains some specific characters to compose a list. Tried first loading the text file into a StreamReader then search line by line for my substrings. Had to write a lot of code to identify my strings, but it worked ok. Then tried loading the text file into a RichTextBox then use RichTextBox.Find(......) to look for my substrings. The " .Find" property makes the code really simple, but using RichTextBox the app was really slow.
Using Stream the loop was completed in about 2 minutes and using RichTextBox in about 30 minutes! I will need to make a lot of searches and using RichTextBox is lots easier, but is too slow. Is there any way to perform search operations using Streams instead making a loop and go looking line by line??? Or what else would be a good solution to search for strings in a text file??

I wrote the code and it works great but then i thought i'd have a little challenge and go above and beyond. i decided to make a highscore leader board system. i used the following variables and sub classes to make it but im having a slight issue...
CODE:
The idea is that i wanted to make the system able to associate a name with a score, sort the score from greatest to lowest, save it to a text file, load it from the text file, repeat.
so heres a quick list of what i have working...
-Stores name and score
-Sorts by score then outputs
-occasional index of -1 issue
-saves score and name to a text file
-loads score and name when the form loads
-CANNOT add new data to the sorted list...
Thats my main issue. When i have data loaded from last time i try to add a new score to the list but then it gives me an error.
InvalidOperationException was unhandled Failed to compare two array elements
-pointing to the line...
In the details of the exception it continues to say...InnerException {"object must be of type String"}
i don't know which parameter its referring to tho, the variable name is already of type string and count is type integer.

I found this code on here to open a text fille, do a find & replace then save the changes, and the code is in a loop that will do that to every file in a given folder. My question is I also have files in sub folders, and more sub folders, and i'm not sure how deep it goes. I want to recursivly go though all the sub folders and do this to all the files, not just the files directly in the main folder.
Here is the code so far:
Code:
FolderBrowserDialog1.Description = "Select Path for files to edit"
FolderBrowserDialog1.ShowDialog
OpenPathVariable = FolderBrowserDialog1.SelectedPath
