I am not sure if this makes sense or not, but I need to process raw text (without any encoding?) that I retrieved from a file recovery application "PhotoRec".With an application like Notepad++ I can see all of the text I need to manipulate but with VB I seem to only get some of the text with other stuff stripped out.[code]I essentially add each line of text to the collection so I can read each line at a time (other processing, etc.)So, as mentioned, with the above code I get text but not all of it. With different encodings I get different versions of the text represented in "current byte". So, how can my .NET application read text like Notepad++ or a similar "raw" text reader app?

I'm making a program that can read a game music file and able to add some texts after it.So far, this is my code:
For Each foundFile As String In My.Computer.FileSystem.GetFiles("E:O2ChinaMusic", _ FileIO.SearchOption.SearchTopLevelOnly, "*.ojn") Dim fileName As String = IO.Path.GetFileNameWithoutExtension(foundFile) 'Filename[code]....
My problem is for example, the game music file's title is "Puberty", as you can see, my code is:
StrItm(1) = title & " INPUT TEXT HERE"
but the only one that appear is the word "Puberty" AND NOT "Puberty INPUT TEXT HERE".
In my website i have a script that return the current song that playing from my shoutcast server in a format of: "artist-track", what i want to do is to take that string and split it to 2 strings: artist and track, in order to do that i wrapped the script in server tag like this[code]...
I've been trying to fix this problem for days, but I haven't been able to successfully apply any of the code that I've found to my project the way it is right now. Maybe I'll need to change the way it reads the file altogether.
Anyway, I'm trying to read through a text file line by line, reading each line into its own string.
I am releasing a BETA version of my program, i have made it so on load, a webbrowser on another form goes to a text document on my website, but how can i get it so it reads the text and then it will know somehow if there is a new version avaliable?
I am trying to write a code that will byte swipe data in a string.
The conversion should take a 16 characters string, and swipe the first to characters with the last two, then characters three and four with character thirteen and fourteen and so on, in this format if the input string is
A1B2C3D4E5F6G7H8 then the converted sting will be H8G7F6E5D4C3B2A1.
I run into problem using: left(mystring 2) and right(mystring -2) because the string to manipulate is an input of a textbox so I fail when I try to use cross data with a StringHandling class, and how to incorporate StringHandling into my form class and without it when I try something like
Dim byte1 As String = Left(MyString, 14)I get an
error saying - Public ReadOnly Property Left As Integer has no parameters and its return type cannot be indexed.
How do you manipulate a text file once you have opened it with Streamreader? I can get the streamreader to open the file and display it in a text/listbox but i cant do things like split and join to it.... It has no effect on the text file when viewed.
This is how i am setting up my string array:
Dim fileName As String = "C: est.txt" Dim objReader As New System.IO.StreamReader(fileName)
I'm trying to do a project which involves reading the text from a number of textboxes and putting it into a string.I'm just wondering if there's an easier way to it other than:
How do you manipulate a string that you have selected from a Combo Box that has been upated dynamically from an MS Access Database table?I have strings that are "1, Surname, Forename" and need to get both the number, and the surname out to put back into a different database table.
I'm having trouble with an infragistics ultragrid using vb.net. I currently have a cell with the value "inner", however I want to be able to display a completely different string for that cell without losing the value. I understand that the cell has two properties, one value property and one text property. The text property is read-only so I cannot simply assign a new string to that.
I am working on a project in VB 2008 and need it to do this:Read first line from text file (using Openfile)Enter line into textbox on formDo some other codeThen Read second linefrom text fileEnter line into same text boxand loop until we have gone through text fileI am not sure how to read line by line from text file then enter it in textbox. I can open the Openfile and get the filename and everything, but I just am not sure how to read from it or enter that line into the textbox.Here is what I have, its not much but its a start:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim FileReader As StreamReader
I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then EnglishForm.Show() ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.
Dim TempFile As String TempFile = "temp.txt" Dim sw As StreamWriter
What would be the fasted method of get a string list of all values within [] in a string of text? For example: [client_name], are you are doing today? My name is [my_name]. The list of strings would be:
I need to be able to read common delimited text that the user enters into a text box. For example the text box would look like this:1,200,02,200,04,120,1203,200,120I need to be able to read the lines and put the data into a multi-dimension array with all the first values in column 1, all the second values in column 2, and all the thrid values in column 3.
I'm a little new to VB, and I'm in a class for it, but I'm trying to do something we aren't going to learn in the class (mostly out of sheer interest) and I need help. I'm trying to read lines from a text file into a listbox, each line representing a new item on the listbox. For example, if the text file reads: [code]I want to be able to take that as is and read it into a listbox, where those words would appear in the exact same fashion; as a list, each as separate items. I've looked at the Help stuff and learned (sorta) about delimiters... but the thing is I don't want to write my entire list in a continuous line separated by commas--I want it to keep reading each line, and moving on to the next, until there are no more lines left. I am thoroughly stumped, and would appreciate it SO much if someone could help. For a frame of reference, this is the point I'm at now with my code: [code]Note that when I run the program, all it will do is read the first line of text available and stop; once I press ENTER in a text file, it decides to stop reading.
im trying to read a online txt file and its not working [code]but it has a uri error i think in doing it wrong but need help with how im doing it wrong, all i want to do is read the text from a file online not from the system should be easy.
Usually, the text file that would need to be read and processed would be local (on the computer the program is run), but for this example, we need to get the data from an online text file.
I have searched on google for nearly an hour now and haven't found anything of any real use. One of the earlier projects we submitted used a similar target, and I managed to get it working fine, however I dont have the original source code with me and I cannot remember how I did it.
I believe I used a Net.WebRequest method of some sort, because I had tried using StreamReader and ended up with an URI error or something like that.
I'm making a calculator that would read a "string" from a textbox and parse it and follow Order-of-Operations/PEMDAS on the string. I have a couple of questions:
1) What would be the best way to parse the code so that it won't just take a "left expression" and "expression" and perform the operation on those 2.
2)How would I be able to make is so that 0 is considered valid, but prevent a 00 or 020 or 002 to be inputed.
I'm in the process of creating a tile based game. This game requires a method to load a text file and write the numbers between the delimiter "-", to a multidimensional array. However, an error message "object not set to an instance occurs. [code]...
For starters I'm using VB 2008 express edition.I have code that writes a string out of a serial port.My issue is that the machine sends data back and I don't know how to catch it.This is my latest attempt at creating an array of characters to create a string later but doesn't work.[code]
This code should read the string "34,56,23,74,69" from a process's memory addresses (in this case notepad), right now it works but very slow and I think it even breaks somewhere. My problem is with the ReadProcessMemory function. I can't make it read an entire mbi.RegionSize into the buffer. I tried everything and now, it only reads 1 byte at a time until the mbi.RegionSize is finished then it checks if the text that was read contains the text I need to be found, then it goes to the next mbi.RegionSize. Now, even with notepad which is very small it still takes 10 seconds to find something and I intend to use it with a much bigger program, so it will take like forever. Another problem is that it only finds the string "34". If I put "34,5" it won't work.
