Finding A Match When Searching Text File?
Jan 13, 2011
I've been writing a socket application in which the client sends a user/pass combination which the server compares to a local text file. I'm only hacvin a problem with a small section where I have a do loop which does this comparison:(the string 'fromclient' has been defined earlier, as the information was received from the client)
fromfile As String
Dim sr As StreamReader = File.OpenText("C:PASS.txt")
Do While sr.Peek <> -1

searching through memory at a given address range, and match a string of bytes specified i.e.
FindArrayOfBytes(Byval str as String, Byval range_start As Integer, Byval range_end as Integer) As Integer
The function should return the address start of where the array of bytes was found.

[Code] Which (when looped) checks all items that contain X, However, I am getting a lot of false positives (i.e. if PGA is legit, PGA, LPGA, JLPGA, WHATEVERPGA will all be highlighted as well) Any way to change .indextof to an .exactindexof or something?

Say I have an array of doubles sorted from smallest to largest. What is the FASTEST way to find the closest value in the array that is LARGER/SMALLER than the search value if an identical value is not found.
Code:
dim myArray() as double = {1.245, 2.45, 3, 4.556, 5.4434}
'LARGER AND SMALLER SEARCH for 3 should obviously return 3 because its in the array.
'LARGER SEARCH for 2.46 should return 3 because it is the closest LARGER value
'SMALLER SEARCH for 2.46 should return 2.45 because it is the closest SMALLER value
I certainly can do this on my own, but I am looking for the fastest way.

Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.

I am working on arrays and I am currently having trouble with searching and finding arrays. In this example, the user should be able to enter a Name, and it will output that person's stats.
Here is the text file (note, I should be able to go to this text file, add a few more names and the code should still work, which is why I am using loops,arrays,text files instead of if and else statements),
Kobe,29,6,4
Allen Iverson,28,7,4
Jason Kidd,12,10,9
So if the user enters Jason Kidd in the text box, this will display in another text box:
Jason Kidd averaged 12 points, 10 assist, and 9 rebounds.
[Code]...
All right now is the searching part. I really do know how to search for what the user entered and display the statement in a text box. I kind of have an idea of how to just get the name, but for it to get the name and then all the data for that name puzzles me even more.-I tried using .contain, indexof and few others.
I know to display the information in the text box will be something like:
textboxoutput.text = PlayerName & " averaged " & PlayerPoints & " points, " & PlayerAssist &" assist, and " PlayerRebounds " &" rebounds"
So basically, I want it to where the user can enter a basketball players name and display the values for that name.

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?

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

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.

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?

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

All I am doing is reading each txt file I find in a directory and finding certain strings in the text then counting how many I find in each file and then once each file has its separate counts it send it to a sql database. I have most of it done, but I cant seem to get the count to separate each file so my problem now is that it counts the first file but when it counts the next file it adds to the first file and so on through all the files
