I was trying to read some file that is encoded with UTF-8 and save it as UTF-16 (Unicode) but it seems not to be fully working as all accents seem to vanish or are encoded to something that can not be read.
Here is the code that i am using:
Public Function GetFileContents(ByVal FullPath As String, Optional ByRef ErrInfo As String = "") As Object
Dim strContents As String

I have to read a 2D barcode that's encoded with base256. When I scan the barcode, it sends different characters as it comes from the keyboard and it changes the focus, turns visual studio in full screen, give the command to send to printer from notepad++.
I guess it reads ALT + TAB, CTRL + P, ALT + SHIFT, etc. and i can't capture all the bytes from the barcode.
I tried to capture the event on textbox KeyPress method with e.handled = True and e.keyChar added to the bytes()
On form.load I set:
Me.KeyPreview = True
And tried also on form.KeyDown with no luck.

I have a scenario where i have to Parse a UTF-16 Encoded CSV file and populate a treeview using VB.Net. I need to parse the CSV files which may also support other languages. how to proceed on this and what classes of .net I can use to solve this issue.
In VB.Net we do not have a provision to parse a UTF-16 file But There is a provision for reading UTF-8 encoded file.The method is OpenText(). I want a similar method but it should parse or read a UTF-16 encoded file.
If On Open File BOM is npt found then i have to treat the file as UTF-8. If BOM compatible with UTF-16 is Found then load it as UTF-16 If BOM is not compatible with UTF-16 then post error message."Not Compatible"
How can I implement all these conditions at once. As the criteria for all is only BOM. how can I know if BOM is found or not. Kindly let me know.
I'm using this code to send encoded text to URL. This code is correct? Because if I send the same encoded string using PHP runs fine, but not in VB.NET
baseurl = "http://myurl.com/mypage.php"

client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET

I know pretty much how to save information into a text file from runtime VB2005. However, I wish to be able to write the information into any kind of form of file that cannot be simply opened and read by anyone (such as text file can be). Is there anyway that VB2005 can do this?

vb.net
Dim filel As Long = My.Computer.FileSystem.GetFileInfo(logfile).Length

fs.Read(buf, filel - 400, 400)
I've also tried with FileStream but i keep getting this error:"Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection."But why doesn't it work with filel - 400 as index? It works if i just switch it with 0?

View 8 RepliesI am learning Visual Basic and I have learned alot of it from the learning section included in Visual Basic Express Edition 2008 but I don't think I have learned alot. I am actually trying to make an extractor and importer for a game. I have the file called Frontened.MNG and I want to make a program that can open the file. Someone else had made the rxtractor but he doesn't have it now. The Frontened.MNG file contains bunch of .DDS files and I want to view them in the program and then be able to replace the .DDS files in the >MNG file and be able to Extract the files out of the .MNG file. I don't just want anyone to do it for me but teach me how to do it step by step. First I want to know is how to view the .MNG file in VB? It should be viewed in a listbox but I don't know how to read this file in VB. I know how to read a text file but I think this is a binary file and it is viewed differently.
View 6 RepliesI want to read a text file that has multiple lines and commas on every line, every comma represents a value, like an integer or boolean. here is an example
50, 100, 50, 50, True, "C:WINDOWSWhatever.jpg"
I want to read each individual line from the text file and read the values after the comma's.
So the first value would be a picturebox height, the value after the second comma would be the width, the value after the third would be the top, after that the left, and then stretch image, and the location of the image. How could I do this?
Here is a simpler version.
Height, Width, Top, Left, Stretch?, ImageLocation

View 3 RepliesI'm making a program in C#, but I want to test out part of the program I'm going to integrate into it in VB, and what I want to do is divide a file into sections. The files range from 60mb to around 180mb, and I know that it is really hard to open files of that size, so for my app I want it to divide the file into smaller sections and put files in a folder temporarily so It could just read them from there. And I want to break it down to about, 5-10mb per file.

i have a .txt file containing 27,607 words, 1 per line, and i need my program to slowly read through and put it into a textbox/label. It only needs to read in order, not randomly or anything. It needs 2 be slow enough that I can read every word being shown, and if possible it would be nice to be able to change the speed but it is not needed.
Public Class Form1
Dim FILE_NAME As String = "C:My DocumentsWordList.txt"
Dim objReader As New System.IO.StreamReader(FILE_NAME)

This is what i tried and all this does is displays 2 words in the middle of the file, then form goes white for about 5 seconds and then the last word in the file shows up and the program remains white. When i try with a txtbox only the last word is displayed.
I have a ERP system which create a PDF file and write it to the disk when the invoice is beeing created. On the other side a have an .NET app, which every 10 minutes read data in that folder and automatically send an e-mail to my customer with the invoice attached.The problem is that sometimes, when .NET app try to read a file which currently is beeing created -> The file is damaged. How to avoid such a situation? Is there a way to e.g. read only file creation time, and if it's "younger" than 5 seconds order app to wait a while?

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:

I ran across my first unicode data, and I am not sure what to do with it. I read the unicode text from a binary file using the ReadBytes method, because ReadChars threw an exception when it tried it. Well, long story short, I have found a way to work with the data, I can convert it using a small Function I wrote, which goes something like this: [Code] And this works wonderfully. It just throws away anything not in the ASCII range, including the BOM at the start of the unicode data.
But I would guess that this method is not very universal and probably not the best way. Are there any VB functions available to do this sort of thing? I was able to find something called Text.Encoding, but there didn't seem to be a reverse of that not that I found anyhow. Any ideas?
i am using VB 2008 and i was wondering if it was possible to have my program create and read a custom file type?
