Asp.net - Character Support - Translate Higher ASCII Characters To Lower ASCII Characters?

Aug 7, 2009

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?

Converting Characters To ASCII Code?

reading special characters within my VB code. ASCII code Char(34) = " works fine but Char(60) = < and Char(62) = > are not being read.

My Code

node.FirstChild.InnerText = Chr(60) & "httpRuntime executionTimeout=" & Chr(34) & "999999" & Chr(34) & " maxRequestLength=" & Chr(34) & "2097151" & Chr(34) & "/" & Chr(62)

Scan A Text File To Determine If It Is A Text File And If It Contains Any Non-ASCII Characters?

Jan 27, 2012

what would be the optimum code in VB2010 that check a file to determine:

1) is it a text file, and

2) if it is a text file, does it contain any non-ASCII characters

Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.

Constants For ASCII Control Characters?

Feb 26, 2012

I have an app that I have been recoding in vb.net formerly written in VB6. In this app I use some ASCII control codes such as ACK NAK ENQ US RS EOT. The VB6 app uses the CHR() function with the proper ASCII codes to handle these but in recoding I would like to use something more meaningful and descriptive than CHR(4) for example.

Counting Columns In ASCII Text File To Enter Data Into An Array

Nov 21, 2009

I am using visual basic 2008 and trying to create an application to plot data from text files. I have several data files of various sizes. They have an unknown number of rows and either 2 or 4 columns.I need to put the data into 2 dimensional array, so value(,) becomes either value(lines,3) or value(lines,1) depending on the number of columns.My program needs to be able to count how many columns there are, and redim value(,) appropriately.I have written a piece of code to count the number of lines (rows) in the file using 'While not (EOF(1)) ....' but I'm stuck on how to count the number of columns.I could ask the user to indicate how many columns there are before the file is read, but I would prefer the program to detect the number automatically.

Import Numeric Data And Export It To Various Text Files Using Ascii Templates?

Feb 27, 2009

I am developing an app that will import numeric data and export it to various text files using ascii templates. I am basically converting the template file into a single string, replacing application fields in the string with {0}, {1}, etc... and adding the result into an array that is then passed to the String.Format(str_Template, Params()) to provide the final output. I have set it up so the template will use the standard VB.Net formatting syntax.

A simple template example:
{<prt_Mark>:G} {<prt_Qty>:F2} {<prt_Length>:F2} {<prt_Remarks>:G}

Define A String Literal Containing Non-ASCII Characters?

May 19, 2010

I'm programming in VB.NET using Visual Studio 2008. I need to define a string literal containing the character "÷" equivalent to Chr(247). I understand that internally VS uses UTF-16 encoding, but when the source file is written to disk it contains the single byte value F7 for this character.

This source file is processed by another program that uses UTF-8 encoding by default, so it fails to interpret this character correctly, attempting to combine it with the following single-byte character. What encoding would correctly interpret the single byte F7 as the single character ÷?

Alternatively, is there a way of expressing a non-ASCII literal that uses only ASCII characters - like using some kind of escape sequence?

Get The Length (i.e. Number Of Characters) Of An ASCII String In .NET?

Jun 17, 2009

I'm using this code to return some string from a tcpclient but when the string comes back it has a leading " character in it. I'm trying to remove it but the Len() function is reading the number of bytes instead of the string itself. How can I alter this to give me the length of the string as I would normally use it and not of the array underlying the string itself?

Dim bytes(tcpClient.ReceiveBufferSize) As Byte
networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))
' Output the data received from the host to the console.'

[code]....

Len() reports the number of bytes not the number of characters in the string.

IO.File.ReadAllLines ANSI Characters (ASCII > 127)?

Feb 14, 2012

I'm using IO.File.ReadAllLines(FileName) to read all lines from text file to array of strings at once. Problem is, text lines include ANSI characters above ASCII value 127 (Scandinavian letters e.g. " (Ascii 196), (Ascii 246) and (Ascii 233). Array is build up nicely, but all chars above ascii value 127 are not shown right. How can I use ANSI character set with .ReadAllLines to correct this problem? In VB6 with "Open Filename For Input As #1 / Line Input #1, txtLine" there wasn't any problem. OBS: This is already solved, found the answer by myself:

Dim myEncoding As Encoding = System.Text.Encoding.GetEncoding(1252) ' Windows-1252
Dim strLibrary As String() = IO.File.ReadAllLines(FileName, myEncoding)
Problem was to find right character set, which was Windows-1251 (ISO-8859-1)

VS 2005 - Not Using Any Characters From Extended Ascii Character Set (128-255)

Apr 24, 2009

I want to explicitly inform my user that they are not allowed to use any characters from the extended ascii character set (128-255). When I try to create a string of these values using the following [Code] It outputs them fine, with the exception of a bunch of blanks in certain areas(I am assuming these characters are unprintable), but I noticed that when I hover over the value of sVal in the VS, the tooltip/quickview of the value is written nicely on one line. Any ideas how to remove characters that would appear to be blank spaces (unprintable) when outputting this list?

VS 2008 - Extended ASCII Characters In Stream I / O

Jul 19, 2011

I am using StreamWriter and StreamReader in VB.NET 2008 Express to read and write ASCII text files. When I create the file and later read it, there is no problem, because I use System.Text.Encoding.UTF8 on both the write and read sides, so extended text is handled without problem. But sometimes, I have text files come in that are just straight 8 bit ASCII without the Unicode BOM... and they get a lot of junk when I try to read in anything with extended ASCII characters in it. It seems like the 8 bit extended characters are translated into multi-byte codes, and since they are filenames, of course, that doesn't work. Since the filenames just have straight 8 bit ASCII filenames. I have tried all sorts of encodings, and nothing seems to work.

The most common character that causes a problem is an "a" ... it is used in a lot of proper names. The funny thing is that sometimes is seems to workout... is there a way to read these types of text files? Some way to just tell StreamReader not to decode the text, just treat it as straight plain 8 bit ASCII text (with the old IBM PC mapping, I think). The one thing that works is to manually edit the input, replacing the extended characters with their un-accented partner and then renaming the files to match the new spelling. Maybe I should just go to read them as byte input and breaking the lines apart in my code.

Convert String Containing Upper ASCII Characters To Byte Array?

Oct 9, 2008

How to correctly convert string containing upper ASCII characters to byte array besides looping through each character and filling the array using AscW(chr)?I know I can do something like:

Code:
Dim bSourceData As Byte() = System.Text.ASCIIEncoding.GetBytes(sourcedata)

But this only works for lower ascii characters (0-127).Instead of ASCIIEncoding I can specify encoding myself (System.Text.Encoding.Getencoding(encoding).GetBytes(sourcedata)). But I have to specify correct encoding in this case, otherwise most of special characters are converted to "?". What should I do if I don't know the encoding?

Read Text File And Sort Data Between Two Characters?

Jun 12, 2011

I have a text document that contains a bunch of data sets. However before each data set there is a number surrounded by brackets. I need to go instance by instance of brackets and pull the number between the brackets and the lines after the brackets until the next bracket. Here is an example of the text file that contains the data. I know how to read from a text document, do substring, do contain function, etc... I just am extremely stumped on how to do this. Here is an example of a couple entries of the text document...

[4188]
LongName=
ShortName=
LauncherDirKey=

Notice how different sections have a different amount of lines therefore a reading a fixed number of lines is not an option.

The first row entries are all displayed correctly in the relavant boxes (except for the images, which for some reason aren't displayed). If another value in the comibox is selected, the other box values don't change and there is still no images visible...

Convert 32-bit Code To ASCII?

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:
