.net - Microsoft.VisualBasic.FileIO.TextFieldParser Changes ± Ascii 241 To ? Ascii 63?
Dec 11, 2010
I am using Microsoft.VisualBasic.Fileio.TextFieldParser to parse a CSV file that was created with Excel 2003. The parser is working great with the exception that it is converting extended ascii values to question marks! So if the file content was:
± 3
The TextFieldParser is returning
? 3
I have tried all of the encodings in the System.Text.Encoding package with no luck. I thought I had it with UTF7 but it was dropping other characters like replacing the + sign with a space.

I use VS 2008, .net 3.5, C# projects. I need do the same functionally like Microsoft.VisualBasic.FileIO.File System.DeleteDirectory. Anyone says referencing the Microsoft.VisualBasic is often undesirable from within C#. Any association with VB from within C# code strikes me as undesirable. Using FileSystem class, this is a perfectly fine solution, but I prefer not references Microsoft.VisualBasic library. That one I would avoid.

I am trying to use Microsoft.VisualBasic.FileIO.TextFieldParser for parsing any format of tab delimited text file that user may have and show the data in web page in tabular fashion.I have sample tsv file with text qualifiers such as quotes saved in different encoding styles for different platforms such as pc, unix, mac saved using textpad. and I am trying to parse these using TextFieldParser. It works for all PC files but fails for mac.

I'm working on decoding a NMEA sentence that is a compressed 8-bit string. I'm having a very hard time of wrapping my head around the bit manipulation needed to convert this string. If someone could get me started with this it would be great.
Here is the incomming string:
!AIVDM,1,1,,A,14eG;o@034o8sd<L9i:a;WF>062D,0*7D
and here is the expected output:

So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?

I typically develop in C# and am quite accustom to using System.IO. I recently ran across the FileIO library and have found that some of the advantages (such as sending an item to the recycle bin) are quite nice to have. Especially in the program I am currently working on.My question is, Does System.IO out perform the VisualBasic.FileIO?My program I am writing will be copying literally TB's worth of information onto server towers. I want to make sure I do not lose any time due to the library I am using.

The below lines does not write anything to the file, ascii.txt. Trying to write the ascii equivalent of hex "88". However nothing is written to the file, nor nothing is asssigned to the variable, ascii.
Dim ascii = ChrW(Convert.ToInt32("88", 16))
My.Computer.FileSystem.WriteAllText("e:ascii.txt", ascii, True)
In excel or openoffice, you can get the ascii equivalent using the below formula. What is wrong with the code?
=CHAR(HEX2DEC("88"))

my name is Altair da Silva and I'm writing a Jeopardy game. I have most of the program done. I got stuck at one part. I have been trying to create lines of codes that would result in a buzzer. This buzzer has to work right after the msgbox with the answer comes up. I'm using a clickhandler and i would like to have this code under the clickhandler. I have tried almost everything. I know that there is a way of doing it, but i dont know how.

This has been driving me crazy for two weeks! I just started learning Vb.net, so please forgive me if I make rookie mistakes. Basically, I would like to convert any type of file to Ascii code. An mp3, .wav, .avi etc. The most I was able to do is convert only the first character of the file to Ascii. Also, I'm not sure what would be the fastest method to do this. SteamReader, FileStream, or BinaryReader. Can anyone explain what method would be best? This is what I have so far:

I'm testing a "simple" login program: it has predetermined ID and Password, after input is correct then you can change the ID and Password. It saves a Non-Encrypted file that has the new ID and Password. Then after the program loads (when it is opened again) it reads the file to retreive the ID and Password, but when it reads, it reads it in 32-bit code, I need it in Ascii (with alphabetical representation) so that I can compare it to the input.I also get an error stating the length cannot be a negative (right after my comment).
Here is my code:
Imports System
Imports System.IO
Imports System.Text

I have a string of ASCII in HEX. ( 5A65726f)so first i split them into 2s >>>> 5A 65 72 6f then i change the hex to integer using these integer i convert them to char using chr() it did the job great, i can see the correct word i want..but it give me an error saying " make sure it has the right format" ( error shown below)
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim hexnum As String
Dim converttohex As String
Dim hextonum As Integer
[code]....
i thought it was the for loop problem...since i will go up to 7 while len(hexnum) is 8 so it would loop again but there is nothing after 8th HEX?so i tried For i = 1 To Len(hexnum)-1 Step 2 ...this time...textbox didnt show anything...+ the same error came up...

I realize this might be a redundant post, but I can't seem to find (through all the searches) the code to do what I need to do...or it's just not working for me.
I have an Intel hex file (containing ASCII characters) such as :041400000262F5226D
I need to convert the values to hex numbers into memory (an array), such as

I'm not sure of the proper combination of conversions I need to get this accomplished. I've tried several combinations of Val/Asc/ etc. but can't get it correct.

I am looking for a function in vb.net which will convert a hex value to the corresponding ascii, like in excel.For example, in excel,

I read parameters from my ECU thru RS232 and display them on TextBox. But the display is ASCII instead of itself. E.g. I read 0x01 and store it in DataReceived, and set
Dim DataRecevied As Byte
TextBox1.Text = DataReceived
The value appeared in TextBox1 is 49 (0x31), which is ASCII of 0x01. How to display 01 there?

I am having a bit of trouble converting a single stored in a string as four hex values. I believe my problem stems from some Unicode hex values not matching the corresponding ASCII hex value above 0x7F (127). For example, I have the following single stored in a string; "518.42" or 0x44019AE1. The char that would contain 0x9A if the data type were ASCII contains U+0161 which will not convert properly to a byte array. My question is: Is there any way to force a string to be of ASCII rather than Unicode? Or maybe there are other recommendations? For reference I have tried both of the following. The first throws a format exception and the second converts to the wrong single.
Private Function ConvertHexToSingle(ByVal hexValue As String) As Single
Try
Dim iInputIndex As Integer = 0
Dim iOutputIndex As Integer = 0

I've tried searching for this, but most people just want to convert hex values into their ASCII equivalents. That's not what I am looking to do.I'm looking to see if VB.NET has a simple built-in function to do this:
Private Function NibbleToString(ByVal Nibble As Byte) As String
Dim retval As String = String.Empty
Select Case Nibble[code]....
Is there a more elegant way to accomplish the same thing as that code?
