Matching Values In Same Text File?
May 18, 2009
How to match one value to another value in same text file. For example I have a this value : 116.71 33.3 in my text file. I want to check whether another same value exist in a same text file or not.
I used this code to find my first value
Do
myLine = myReader.ReadLine()
Loop Until myLine.Contains("*+*+* Top *+*+*")
Do Until myReader.EndOfStream
myLine = myReader.ReadLine()
[Code] .....
Once I get the value I want to check another same value exist in the same text file or not.

I have to scan through documents. Excell, Word, txt, ect looking for company names that match a pre-difined list of companies.I then email the companies some specifics in regards to that doc.The problem I have been having recently is that the list of companies keeps growing and I am starting to miss some more than I used to.What I would like to build is a tiny app that has 2 Text boxes.1 on the left for input (where I would copy/paste) the document text I receive.and one on the right for the output where it will highlight any line that contains the name of any of the pre-defined companies.
I started toying with the idea and so far I have form with a SplitContainer. Within that SplitContainer each side has a TextBox... Below the Textbox on the left hand side splitcontainer I have a submit button with no actions currently assigned to it.

i created a form with a combobox that lists out Assignments ( assignment 1, assignment 2, etc...)......what i need to do is let the user choose an assignment, then the program should look for the matching text file in a folder, ex: user picks assignment 1, and the program will read from assignment1.txt and display the result in a listbox. I have everything except the coding to match what the user chooses and the text file to streamread.

I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")
Dim*SaveTextFile*As*String*= IO.Path.Combine("C:Test2.txt")

I am wanting to check two TextBoxes to see if they both have the same value. If they don't, then to show an ErrorProvider and do something with some buttons based on the input. I have all the textboxes in a List like so:
vb
Private MyList As New List(Of Elegant.Ui.TextBox)
vb
[code].....
I can go through the list to check if they have a value or not but want to check the last two in the list to see if they contain the same value. This is what I am doing to check to see if they are empty or not.
vb
Private Sub CheckMe() bIsEmpty = False For Each itm As Elegant.Ui.TextBox In MyList If itm.TextLength = 0 Then

I have to save the text boxe values of a form to a text file almost like a data record. I will be saving an Employee First Name, Last Name, Dept Number, and Phone Number. This I know how to do using streamwriter.
next form which we have to use stream reader to load one record at a time. The form has a next button to load the next record. How do I seperate each record (I am sorry for calling it a record if this is inappropriate) when use streamreader and how do I load a record at a time.
I know how to open a file and use streamreader, I just don't know how to read one record at a time and move to the next one.

In VB6 datacombobox there was a property that you could set that filtered the item list as you typed in the combo box (extended matching I think it was called) so that as the user typed more characters in the box the filtering progressively narrowed down the number of items in the list.The .net control does not seem to have this facility, or does it?Do we have to programatically do it now?

I'm trying to design a words game that's give you the first two letters from the word and you insert the rest to make a word (for now I'm just using "co" as example and I have just one table in the database for it). The word will be written in textbox to be compared to a database field. If the word exist in the field the word will be displayed in a label with blue color and the score will increased by one if not the word will be displayed in the label with red color. This should happen three times with three words and I have different label for each one.
the name of my database is database1 and it have one table "A" wich contain "Comp" and "word". I tried this game with array of word before and it was working. Now I'm trying to use database instead of arrays but its not working. [Code]

In this exmample textData is a string of text and alpha is a single letter a through z or A through Z. I don't need the criteria to be case sensitive, but I do need only the first letter of textData to match alpha. I have tested the LIKE comparator and it does not return all records that begin with alpha.

I know similiar question have been asked but they are a little different so here I go. Basically I have a game in which the user enters their name and they get a score. This name and score then get recorded when they end the game as follows:
Dim userdataSW As New StreamWriter("E:GameScores.txt", True)
strline = frmVictory.TempPlayerName & "," & frmVictory.TempPlayerScore
userdataSW.WriteLine(strline)
userdataSW.Close()
userdataSW.Dispose()
What I then need to do is sort these values in the text file from largest to smallest (based on the number not the name but I still want the name to be assosiated with that score) so I can have the top 10 scores appear in a hall of fame type thing.

I have been trying to find out how to do this for days now, so I am finally asking how. I am newish to programming. Here is my problem.
I am trying to extract x,y,z coordinates from a text file arranged as such:
x,y,z
x,y,z
x,y,z
etc.
I need to be able to extract the x column into an array, the y into an array, and the z into an array. I learned how to pull it into a string, and how to split for every line, but i don't know how to split after each comma and separate them.

I need to write values, mostly doubles into a text file in VB.NET. I ported the code from VB6, but the performance of the VB6 write#fileID, vars) in VB.NET, is very bad, it introduces a delay of about one hour. I have tried out the streamwrite, and its performance is good; it's actually faster than VB6 write.
I am using the write(string) method for the streamwriter, and I am concatenating the values using variable names as follows: streamwriter.write(var1 &","& var2 &","&....&","& var n &","). This version of write enables me to have more than one variable written to file per statement. The problem that I have is that the content of the file is incorrect, unlike the one produced by the slow VB6 write in VB.NET.
Is there a better way of achieving this requirement; preferably using the streamwriter? I cannot use the streamwriter.write(double), becuase I'll have to use multiple lines as I am writing about 800 vars in convergence test loops resulting in a total of just over 2 million writes.

Regex in VB2008.I have a file system directory that my code is watching. When a file is placed in that directory my code kicks off a processing application. Based on the filename structure, the code will perform different processes. So I need to match the filename structure specficially to get the correct processes to run on that file.My file name structure is: IK2YYYYMMDD_VV.e;where YYYYMMDD is well, the year, month and day. And VV is a verison number from 00-99 If the new file saved in the directory match this structure then I want a TRUE returned. From a filewatcher I get the filename as an "e.Name" (FileSystemEventArgs) variable. My current code to see if it matches the baseline structure is;
Dim IKPred2Match as New Regex ("^IK2.*\.e$") Dim ValidIKPred2Match as MatchCollection = IKPred2Match.Matches(e.Name)I've tried many different regex match patterns, and just can't seem to find the magic one.

How would I go about reading a textfile, finding values and using the values in the program?Now I want the program to read the text file, find [1], use the first line after [1] as value for a variable, and the second line as value for another variable. After that I will run some code with the values and then do the same thing again for [2] etc.

I have some large csv files (1.5gb each) where I need to replace specific values. The method I'm currently using is terribly slow and I'm fairly certain that there should be a way to speed this up but I'm just not experienced enough to know what I should be doing. This is my first post and I tried searching through to find something relevant but didn't come across anything.
My other thought would be to break the file into chunks so that I can read the entire thing into memory, do all of the replacements there and then output to a consolidated file. I tried this but the way I did it actually ended up seeming slower than my current method.
Sub Main()
Dim fName As String = "2009.csv"
Dim wrtFile As String = "2009.1.csv"

I read a csv file into my .net program using ado.net and display it in a datagridview.In the file I have two rows. The first column is a component id, and it is supposed to be numeric. But the user can edit the csv file before having my program load it, and accidentally put text there. That is something I want to edit when he presses a button to add the data to the database. So let's say he puts a value of A in the first record and a value of 1 in the second record. Or vice versa. What is displayed in the dgv is a blank in the first record and a 1 in the second, or 1 in first and blank in second. If both csv records are A, then what is displayed in the dgv is an A in both the first and second records. I don't understand what is happening. The fact that there sometimes is a numeric in the column makes it think it is a numeric field and therefore only display numerics and blank otherwise, and the fact that there's always text in the column makes the code know it is a text field?

I've a got a homework assignment that chooses one of four values in a list box, stores it in a text file. Secondly, on the display click event it should access the text file, read the line, store it in a variable and then display the totals in a text box. Works sort of fine except that it doesn't display the totals correctly. Code for both buttons is below. The variable are assigned in the mainform (Tried also in the display button and didn't change anything). The save button works fine and stores fine in the text file, it's just the reading that's the problem.

lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?
