Dim data() As Byte = System.IO.File.ReadAllBytes("c:1.txt")
label1.text=data(1)
How do read first byte,last byte(get the value) from my text file? From my file, i want read the first char "1" and last char "2" through read byte method and show in label.
i m using readallbyte method to read my log file. How to get first five bytes in every lines to do the comparison?
Dim data() As Byte = System.IO.File.ReadAllBytes("c:1.txt") 'read log file in bytes Dim lines() As String = System.IO.File.ReadAllLines("c:1.txt") 'read log file in lines
Let's say:
For i=0 to 100 If lines(i).startwith("212330") Then 'code End If Next
The value 22330 is read from the file in byte. But i not sure whether can find the byte value by using readalllines method.
Is there any special way of reading a pdf file into a byte array? The reason I ask...I want to fax a pdf file using faxDocument and FaxServer. My current code is working fine for everything else. Now I know that in the documention it says it should not work for pdf. But I can get some pdfs to send and some do not. When I fax a pdf through windows, it works. [code]....
Some binary files have application variables at the end if you open it with a text editor you can see these variables. Now when I read these files into the processor memory the program does not work properly, however if I read a file without this it works fine. So how can I read a byte[] array to EOF so that when I pass that byte array into win32 api create-process it will create the process without corrupting the program?
I'm trying to read the binary data from a binary file with the code below but the it's return the value in the byte array. How can i read the binary data from the binary file and then convert the data into string?This is how i create the binary file.
Dim fs As New FileStream(Application.StartupPath & "Agency.dat", FileMode.OpenOrCreate) Dim bf As New BinaryFormatter() Call bf.Serialize(fs, GAgency)[code]....
I have a txt file that I need to read into a listview, but I need to read from a specific line in that file. Below is a sample of the txt file to read,

ok i have image that i bind info in it and i want to read the info now from file (FileStream) its workbut i want to do it not from file so i need to use MemoryStreamhere the example that work and how i do it now how i make it work with MemoryStream (with byte = My.Resources or PictureBox1.image)
Using FS As New IO.FileStream(image, IO.FileMode.Open) FS.Seek(0, IO.SeekOrigin.End) While Not FS.ReadByte = Asc("|")
I have a DEM file(Digital Elevattion Model File) and I am trying to open the file,where we have Latitude and Longitude values inside the DEM file.And, Now I have opened the file using Filestream and Read the file using BinaryReader.But, I am having a trobule in getting the values of Latitude and Longitude.I am getting Byte values randomly as 1,202,31,271 etc.But, we dont have latitude and longitude values more than 180,and also I am not getting 16 bit UInt values.For example, the values should be like Latitude 20.00416666666667 and Longitude 39.99583333333333.So,read the correct Byte values of the DEM file.The code I have used till now is:
Dim fs As FileStream = New FileStream("C:UsersadminDesktopHeader and DEM fileE020N40.DEM", FileMode.Open, FileAccess.Read) Dim rd As New BinaryReader(fs) Dim convertDB As UInt16 For i = 0 To rd.BaseStream.Length
I have a simple byte array: Dim TheBuffer() As Byte={0,1,2,3} and I want to store it to a TEXT file. Is there any simple way of doing this? I want to enter the text file and see the array 0,1,2,3. don't want binary format etc.
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.
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.
Ok so I have a combo box that lists a set of names. What I want to do is match a selected name to a text file and read from it. The text file contains the same name and has grades listed below:
i have 5 textboxes in a form. I have a streamwriter that writes all of their text to on text file like this:

[code]....
I was wondering how to get the text under the each number and place it in the corresponding textbox.

I am trying to read a text file into a text box, and show the progress bar loading. Sometimes if the text file is big, i don't know when it will finish reading it. This is basically the code i use to read a text file, but i don't know how to show the progress bar.
I have a text file containing 10 pieces of information. I want to read the information from the text file and put it in text boxes on a form, so that the user can view the information and edit if required. What is the best way of approaching this?
I have a client(VB.Net) that receives a packet from the server(Java), and for a while I struggled with some really weird packets that didn't make any sense, eventually took a look at the Java servers source and saw packet structures like this...

and so I came across the term of bit-masking. After a few failed attempts and unsatisfying google searches later, here we are.In short, I need to read a byte array bit by bit.
how to do this for vb6 however i am using vb 2008 and the code for vb6 does not seem to work.
I have designed a form with a text box on it, and a command button underneath. The idea is to run this as a sort of stiky notes section.
I want the text box to read rich text into the textbox (C:\\stickynotes.rtf")
Then i have a command button underneath which i want to save the content of the rich text box to the rtf file (C:\\stickynotes.rtf). This is so that the user can edit and ammend information.
here is some code i have so far
Dim fileReader As System.IO.StreamReader fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\\stickynotes.rtf")
So far what i have is a button and a text box and when you press the button it my.computer.filesystem.readalltext(from this file as string) but what i want it to do is to read all the text in that file minus whatever is in parenthesis so like lets say the file has saved into it, hi my name is bob but my realname is (jeorge) that when you press the button it reads and shows everything in the file minus jeorge which is in parenthesis
im trying to have the user press a button and a window pops up to select a file. then it reads the file and puts it in a text box. how could i do this?
I'm trying to read a byte array into a string however it's array is filling up from a dll in the following format. [Code] now its decoding the first byte but I think because of the next [0] it's not completing the whole array. This is the code that I'm using:
