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]
View 4 RepliesI 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.
Here's what I have that Doesn't work (I have one button, one OpenFileDialog, and a label named Status):
Public Sub ProcessBytes(ByVal Bytes() As Byte)
Status.Text = "Status: Processing . . ."

I've got a program which reads a text file, in this file there are 2 or 3 lines between paragraphs. However when displaying in my textbox on my form i have 14-18 lines. Why? and how can I remove them?
View 3 RepliesOk 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.

I'm having trouble reading a file into a filestream from a CD. I get 'Access to the path denied'. Works fine when reading a text file from a local drive, but getting error from CD. Dim fs As New IO.FileStream(filename, IO.FileMode.Open)
View 12 RepliesHere 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?
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].....
The file format has already been explained to me, and I can easily view it in notepad to understand it. It's basically a text file with a fancy extension and what not. The only problem is that I need to read it and pull a certain span of data from it.Here's the basic format:
8200
3251
1
[code].....
This is the first 10 lines, which is useless data for me. However, right after the first 10 lines, is a span of an unknown quantity of lines that I do need that are formatted like so:grassC:Program FilesMicrosoft GamesHalo Custom itiondatalevelsestlood_creekitmapslood_creek groundThe first line is the name of a bitmap assigned to the ID, while the second line is the path to the bitmap.Finally, after the unknown span of lines, there are two lines that go in this order:01Which I can safely assume at this point that the list no longer needs to be read.What I need to do is be able to open this file, skip over the first 10 lines which are completely useless, and then pull out the unknown gap of lines, and then stop reading when the line is '0', or at the end of the list.
I have a text file called: list.txt This is a list with all kind of lines like this:
14II_ARM_S_CLO_CLO_CLOVERIDS_PROPITEM_TXT_01194611IK1_ARMORIK2_CLOTHIK3_CLOAK=TRUE==200050000====PARTS_CLOAK=1==11=1===11_NONE Ofcourse every line has different numbers and letters.
The complicated bit is this:
I want to let Button1 check whats in TextBox1.Text and search "list.txt" for it. When it has got a match (there is only ONE of these numbers in list.txt).For example TextBox1.Text = "IDS_PROPITEM_TXT_011946". And I search for that so I find the line above. Now I want 3 other textboxes which show the 21st, 22nd, 23rd column/number after "IDS_PROPITEM_TXT_011946". And they should be editable by changing those 3 textboxes and clicking the apply button.How can I best do this, and please give a little example.
Is there a way to set BitConverter to produce Int32 values from BigEndian-encoded bytes?I feel like there might be a way to temporarily "set" the encoding to BigEndian before calling BitConverter, but I haven't figured it out.Right now I'm just reversing the 4 bytes before calling BitConverter, I guess I could create my own function that adds the bytes with the appropriate multiplier, but it seems a little inelegant if it can be done simply with BitConverter.
