Program Has Long Freeze While Writing Text File

Feb 26, 2012

I am making a program that loads, edits and saves 5000 rows x 100 columns of data. The data is stored in a datagridview. I use these commands to write the file:

dim z as integer
dim z1 as integer
fileopen(1,"c:drawermyfile.txt",openmode.output)
for z=0 to datagridview1.rows.count-1
[Code] .....

Every time I issue this command the whole program freezes until the computer is done writing the file. Is there some way I can get it to write this file without freezing up the program? Or, perhaps a better way to write this large data file?

VB Writing Text To A Text File?

May 10, 2011

I am creating a basic programme in VB as a piece of coursework. Most is going fine however I am having problems saving text to a text file. Let me start by saying I know how to save the text to a text file, but I cannot save it how I want to. as you will see from the code below currently it saves to a file called OrderInfo.txt on the D: drive (which works fine).

However as I will be submitting the code via its VB state (i.e. just in the test mode and not published as an exe or anything) I want the file to save in folder \Assignement\Orders\OrderInfo.txt. I dont want it to be drive specific as I dot know where the lecturer will decide to put the file so it may be on D;, E: C:\Documents and settings etc....

Is there a way I can set it so that it will just look in the local folder where the VB is being run from much like you can with html? So instead of assigning a letter I can just type \Orders\OrderInfo.txt.

Private Sub cmdConfirm_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdConfirm.Click
frmSummary.iOrderNo = frmSummary.iOrderNo + 1
Dim FILE_NAME As String = "D:\OrderInfo.txt"

Searching File For Text?

May 28, 2011

I'm trying to make a script that searches for multiple .TXT files in a directory, and then searches the text of each file for a matching string(ie. "turtles"). It will search each file for the word "turtles". I've been on google trying to figure this out for a while, I'm guessing StreamReader is the way to go?

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim l_Dir As IO.DirectoryInfo
l_Dir = New IO.DirectoryInfo(MyPath)

Searching Text File From Certain String?

Feb 1, 2010

I've got two text files. The first has got a list of certain keywords. Each one if these keywords are fed into a combobox. Now, when I choose one of the items from this combobox, I want to search the other textfile for the same keyword and read from that point to the next keyword. And then feed each line into a listbox. Perhaps I should use an INI-file for this purpose, doesn't really matter for me.

The textfiles have this structure;
Textfile1:
London
Oslo
New York
Hamburg
Amsterdam

The second textfile has this structure;
Textfile2:
'London'
Apples
Oranges
Pears

'Oslo'
Pasta
Salami
Monkeyballs

'New York'
Dada
Duda
Dadadish

Is this possible? The reason I want to do it this way is to create a fully dynamic system. One which relies fully on whatever information is stored in these textfiles. I'm gonna build pretty complex strings from these results later on. So far, I've got this to read the first file and add each line to the combobox:

Dim oReadMenuFunction as System.IO.StreamReader
oReadMenuFunction = IO.File.OpenText("textfile1.txt")
Do While oReadMenuFunction.Peek <> -1
Dim LineIn as String = oReadMenuFunction.ReadLine()
Combobox.Items.Add(LineIn)
Loop

Ini - Searching For A Specific String In A Text File ?

May 18, 2012

There's an INI file that I want to access and read information from. This is the complete content of the INI file in question: http:[url]....I believe it is because of the [ ] tags in that INI file. Because they work if I remove the tags.My program has a bunch of comboboxes, trackbars and checkboxes. These items will be filled by the information taken from the INI file.For instance, ini file has these lines;

bCrosshairEnabled=1
bDoDepthOfField=0
bFXAAEnabled=1[code]...

Example: I want the checkbox8 in my form to get checked if bFXAAEnabled has a value of 1 or unchecked if it is 0.

Searching A Text File And Returning Results?

Nov 25, 2011

I have been taking a class in Visual Basic and am currently working on my final project which I am having some trouble with. I am using Visual Basic 2010 express The project is to create an application that will store data in a text file, specifically, Last Name, First Name, Customer Number, Address, City, State, ZIP Code, Telephone Number, Account Balance, and Date of Last Payment. I have gotten everything done except the ability to search the file by Last Name or Customer Number. I have no idea how to go about this? I was thinking of ways to use indexof or Readline to be able to search the data, but I'm not familiar enough with the code to come up with a good solution. Below is a picture of how my form looks..As you can see, I'm currently using 2 separate forms to get the data from the user. Here is the code for Form1 which is the "Customer Accounts" form in the picture.

Imports System.IO
Public Class Form1
Public customerFile As StreamWriter ' Object variable
Public customerFile1 As StreamReader ' Object variable
Public strFile As String

[Code]...

There isn't enough room to post the code for my secondary form, but you get the idea. I would like to be able to enter a search term in the textbox on the bottom right of the form, and either search the data as its displayed in the listbox, or search the actual file? I was thinking that the results would be displayed in a messagebox?

Nov 17, 2009

How do I start writing a program that has 6 text boxes. A person would enter a member number if they have one, number of movies rented at $1.80 a piece. A Text box should then display Total Rental Price, and if a member number was entered, a 10% discount is given (the total of the discount shows up in another text box) and after there discount is applied the Amount Due is displayed in yet another Text Box.

My boxes are named:

memberNumberBox
moviesRentedBox
rentalPriceBox = $1.80
totalPriceBox
discountBox
amountDueBox

This is all supposed to happed when the customer clicks on a calculation button named: Button1

This is what I have so far, but I don't even know if this is correct, as I am getting 1 error relating to a name not being declared. Please help and clue me in to where to start!

Searching A Large Text File And Returning A Searched Word?

Jul 12, 2011

My app is a Bible Reader. At load up I can choose Genesis Ch1 and its entirety pops into a rtb. I enter a word to search for like 'God' and hit the SEARCH button. The results I get are initially what I want. I get the verse 1:1 In the beginning God created the heaven and the earth. But then the app replaces the script with other words containing God, but all jumbled up. Here is the code I am using: Private Sub ToolStripButton2Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton2Search.Click Dim stSearch As String stSearch = Me.ToolStripButton2Search.Text For Each Line As String In File.ReadAllLines(Path.Combine(Application.StartupPath, "Bible VersionsKJV 1611King James Version of the Holy Bible.txt")) If Line.Contains(Me.ToolStripTextBox1.Text) Then Me.RichTextBoxViewer.Text = (Line) End If Next LineBryn Ryver
