I am making a recipe book that calculates the amounts of each ingredient needed for a dinner.The user inputs the number of people they are cooking for and then my program works out the amounts of ingredients needed, simply by * number of people.I know how to read from text files using commands such as: My.Computer.FileSystem.ReadAllText()But does anyone know how to take text for a text file, then multiply the contents of that file by the number of people?The text file only stores numbers, but I want to multiply each line seperately..Instead if getting the result of 10050*3, I want 100*3 and 50*3 on a seperate line.[code]For this to work, I suggest downloading the full project.You will also need to create a folder with two text files inside it. This will not work without them. "QuantityList.txt" and "IngredientList.txt".
Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
Catch MsgBox("Selected Hero currently has no File with us.") End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
I current have an app that I am trying to create. I have 2 List boxes, a textbox, and a command button.What I am trying to do is take about 100 text files that all have certain text in them that I need to change at run time to whatever I put into the textbox. For instance Each Text file has my old company name and I want to be able enter my new name into the textbox and click the command button and the app will open each text file, find the text that I specify and replace it with my new name then save the file into a specified folder.What elements should I be studying to make this happen? So far this is what I've come up with:
OpenFileDialog - to open the file
StreamReader - to read the text files and find the text that I specified
**Not sure on the replace method**
StreamWriter - to write the text from the textbox to the new file
SaveFileDialog - to save the file to the specified location

I'm trying to make a program that can read .mp3 data (Such as Artist, Album, Year, Track number, etc), but I need to be able to do two things that I have no clue how to do:
1. Read starting from a specified string (E.G, On one line it states: [code]
2. Read until a specified string (E.G, On the previously stated line,I need to read starting from what I said, up until.
I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET):
[Code]...
I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file.
I have many text files in a folder. What I can do now is to read through one text at a time and insert it into the database. My little app reads a text file when I debug it. So, I need to run it several times to read all those text files and import them into the database.
My question is how to read multiple text files inside a folder at a time. Here's my code which works fine but it reads only one text files at a time.Private Sub btnRead_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRead.Click

I need a way to loop through a folder and check if there's text file. But I cant get it right. Can anyone show me some code or links ? I'm using VB.NET, .NET 3.5
I am a new to visual basic 2010 and I am creating a small game program that will have players names and keep their scores in a text file. I placed the text file in debug folder for debugging purposes. The code below has been simplified for demonstrating purposes only.
Any simple/easy (emphasis on easy, I am a major beginner) to read through text files quickly, search for strings and pull information. I am currently using the 'StreamReader' function and 'InStr' command, but the files I am working with are gigantic and this is taking from 1/2 an hour to a few hours to work its way through.
Here is a sample of the code I am currently using - poke fun at will, I am a major newbie. strContentsTime1_jntfor=0 Do Until strContentsTime1_jntfor Is Nothing strContentsTime1_jntfor = objFile1.ReadLine() 'look for string 'time' strFindStringTime_jntfor = "time" [Code] .....
I'm saving path's to text files in a text file so the user himself would be able to add new data. My problem is that I need to make a loop that reads from these different text files and stores the data (but I don't know how many there might be.) This was my try to it:[code]
creating a function that reads in data from multiple textfiles into a combobox. The function just needs to read line 1 into from every text file into the combobox.
When reading data from an excel file the driver tries to detect the data type of a column based on the contents of that column.
Once it's decided on the datatype then data that is not compatible with that datatype is simply ignored and returned as Null when you read that column using ado.net
For example if most of the column contains numbers then the occasional cell containing non-numeric data is returned as null.
Is there a way to force it to always return all data as text no matter what the actual column contains. ?

Obviously, I need a way to loop through a folder and check if there's text file. But I cant get it right.
my knowledge of VB.net is limited and i'm really trying hard to figure this problem out...
what i did was create a list box and populate it with a directory ("C:Documents and Settingsuserfolder1")...
once the listbox displays the files from the directory, i want to select a certain file and that file will be opened up in a rich text box.What i found to display the directory in a listbox is:
Dim directory As New IO.DirectoryInfo("C:Documents and SettingsjtanDesktopRECV") Dim diar1 As IO.FileInfo() = directory.GetFiles() Dim dra As IO.FileInfo Dim files As String
Is it possible, create a button that can start looking for files in a particular folder and open and close each 1 of them. Eje: Search in c: est (here open and read all files on folder in texbox) test.txt, test2.txt, ... Open 1 and close to open 2, close and open 3... I write the folder to search, and program find and open and close all files in the folder.
I have recently decided to give .net another chance, but i have a few questions about it before i get really into it. RE: Files, I use random access files to store data as opposed to databases (namely i don't see the need for a database for storing so little information(records <200 max) knowing that it is an older system and less "cool" i don't care...) Will vs2010 express read, write to random access files? Would it be done kind of like vb6 (which is my current vb version)? I will be needing to print the text of rich text boxes, is vs2010 express capable of doing this?
I am writing an application that will use a OpenFileDialog control that will read a text file into memory and later process it.
I do have the following filter: Text files (*.txt)|*.txt|CSV files (*.csv)|*.csv|Spaced Text files (*.prn)|*.prn|All files (*.*)|*.*"
When I navigate to my test folder that contains a single .txt file, I see that file. When I change the filter to *.cvs that files goes disappears because it has a .txt extension. That is good. But when I select All files *.* it does not re appear? Why and how do I make it appear.
Ok, so say the string is: <a href "[URL]">abc</a> And I just want to get the text "abc" from between the <a href "[URL]"> and the </a>. How would I do so? I dont think I can use the split function, can I?
I'm trying to do is read a text file from a certain line to the end of the file. For example, say the text file is:
Hello Everyone My Name Is Tyler
I would like to be your friend. Would you be mine? I like dogs, cats, and basically any animal. I play the tuba and am in a band at college. I go to UMass. Do u like UMass?
(none of the above info is true FYI)
My code would look like this:
Dim hello as string= io.file.readlines(c:/text.txt)(0) Dim everyone as string= io.file.readlines(c:/text.txt)(1) Dim myname as string= io.file.readlines(c:/text.txt)(2) Dim istyler as string= io.file.readlines(c:/text.txt)(3)
But say I wanted it to read from line 4 to the end of the file? The entire description I would want to save as one variable. How would I do this?
