VS 2008 Read File Not Reading Fully?
Nov 6, 2010
I have several files that I am reading in and 'scrubbing'. The scrubbing is simply taking certain HTML tags and changing them - no big deal.When I read in the files (one at a time), they read and then I scrub them.The files stop reading mid-way *no matter what* the encoding type There is no stop character or anything, it is simple HTML and I do not see any reason why the file isn't being read I have attached one of files that is having a problem and the code is quite simple:
Dim oRead As New System.IO.StreamReader(Dir & "" & FN, Encoding.ASCII)
EntireFile = oRead.ReadToEnd()
[code].....

I am trying to read in demographics from a text file. What I am trying to do is use the commas in the text file as a stop and starting point for each field. Instead of explaining all will be clear once you look at the code.
Dim filecontents As String
Dim newlineindex As Integer
Dim numindex As Integer
Dim credents As String

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?

I have an XML file, shown below:
Code:<?xml version="1.0" standalone="no"?><!--RISInsight server settings--><Configuration> <Server> <ConnectionMode>ServerName</ConnectionMode> <ServerName>(local
[CODE]...
The problem is that I want to read the complete XML file, however because I am repeating the same XMLElementName it only seems to read the first element, the code I am using is the following:
Code: Dim reader As Xml.XmlTextReader = New Xml.XmlTextReader(Application.StartupPath & "settings.ini") Do While (reader.Read()) Dim addToList As Boolean = False Select
[CODE]....
Is there a way that I can make it continue to read the XML file?

Is it possible to open an html doc that was created by my vb 2008 application once it's been created? I have it created on my desktop, once it's there I'd like it to automatically open in firefox. I tried
Using sr As StreamReader = File.OpenText(path)
Do While sr.Peek() >= 0
Console.WriteLine(sr.ReadLine())
Loop
End Using
For starters, but it doesn't open anything. It creates the file just fine though.

Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?

I'm new to Visual Basic. I'm trying to get this code to read a .txt file line by line. If the only thing that the line says is "B" it should add one to the intTotalBoys integer and so on with G for Girls, F for Fathers, and M for Mothers. I'm not sure why it won't work. [code]

I need to read in each line of a file that is comma delimited and I know how to do this.ut for this file, some of the values have quotes around them that contain commas and others do not. For example, the name field has "Doe, John and Lisa" and the other fields do not. How will this be handled? Will it read that whole field in as one or will it still seperate it as seperate fields?

I have several quesions about reading/writing structures from/to files.In a scenario when I open a data file having its own header and variable data fields I create a structure that represents a header consisting of 9 bytes:
Public Structure HeaderInfo
Public DataField1 As Integer
Public DataField2 As Byte
Public DateField3 As Integer
End Structure
I'm using this code for the time being:
vb.net
Public Function ReadHeader(ByVal FileName As String) As HeaderInfo Dim ReturnInfo As HeaderInfo Try Using br As New IO.BinaryReader(New IO.FileStream(FileName, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)) With ReturnInfo
[code]....
The first question is - can I fill the structure directly somehow? Some structures are very long and filling them this way will be tedious. For example, if I know the length of the structure I could read the needed number of bytes in a byte array and somehow marshal these bytes into the structure.I can use Marshal.PtrToStructure, but then I would need to get an IntPtr of my byte array. I use <Serializable()> attribute for my structure.

Ok so there is an XML file for a program that already exists that stores a list of files along with other information.I need to open this file and read the file names and then potentially add files to it if they DO NOT already exist in the file.It is very important that I not wipe the XML file and have to write it from scratch every time.

Here is my code for reading a Binary file:
Dim fs As New FileStream(filepath, FileMode.Open)
Dim str As String = ""
For d As Integer = 0 To l - 1
Dim byt As String = Hex(fs.ReadByte()).ToUpper
fs.Position = d
str+= byt
Next
str becomes:
20202CB962AC5975B964B7152D234B
But when I open the file in a HEX editor, it's:
202CB962AC59075B964B07152D234B70
Why are the 2 different?
