I would like to pass a whitespace character by using the System.Text.Encoding.ASCII.GetBytes(" "), and System.Text.Encoding.Unicode.GetBytes(" ") , where " " is the whitespace Character required. What do I need to type (" ") to get a whitespace character passed.?
View 6 RepliesI am sending a DDE message to a client using System.Text.Encoding.ASCII.GetBytes(item) . However, before the message is actually sent, I would like to get the message coded where if the item="Ask" then item=Ask (string variable) and so on. The code is:
Protected Overrides Function OnRequest(ByVal conversation As DdeConversation, ByVal item As String, ByVal format As Integer) As RequestResult

I am writing a console application, which reads emails from different email boxes and processes through them. Emails are received from various automated systems. The email messages are logged and/or sent forward.
The problem is that some emails are encoded in UTF-8 and transfer-encoded in quoted-printable which messes up special characters (mainly ä,ö and å). I have not found any solution to convert them in readable format.
For example "ä" in quoted-printable is "=C3=A4". Using a normal conversion methods the result is "ä" (gibberish).
I shamelessly ripped this example conversion table from here: [URL]
[Code].....
So how do I get the real codepoint from UTF-8 value? I'd rather not use any external libraries. Besides I've tried a couple already and they failed.
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 got a problem when receiving data from networkstream that was converted from bytes to string.. the output would be the same but when i compare the the string generated from Encoding.ASCII.GetString() compared to the actual string, the output is not the same..
This is my code..

my server pings to client..is there any instance that when the string will be converted to bytes, the string will change?
I'm using this to write to a text file[code]..
but i need to change the encoding from the default. how do i change the default encoding to ASCII?
system.text.encoding?
everything in outputText is written as a string and then concatenated into outputText.

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 have text like this format "term: 156^^^:^^59 datainput" Or "term: 156^^^:59 datainput" or "term: 156:^^^59" The "^" represented white space. Notice the white space between the the two numbers and the colon. There 2, 3, 4 or even 7 white space between the two number. I want to remove these white space so that the text can be in this format:

View 8 RepliesI'm Alan and I'm writing a little program (beginner), but I'm stuck and I can't get any further. So I hope one of you guys can help me solve following problem.Let me explain what I'm making, so it can give you all a better perspective.
For a this project I'm receiving data via the RS232 communication port. So basically I receive bytes. These bytes are converted to a string. So for example I receive this:"BAA" this is good because I can get the correct decimal value for "B"(66) and "A"(65) using the command asc("A") in .NET.but sometimes I receive a character that exceeds the 0-127 limit for example ""(128) (please see [URL]..But now when I try to get the decimal value of "" I get 63 instead of 128. I searched the Internet and forums for an answer but I didn't find one that fits my problem.
So if it's possible, can one of you code experts explain me how to fix this problem ? It would help me a lot. I hope I described my problem clearly, but if there are some questions,
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?

View 6 RepliesI am working on a client/server based application and I have run into quite a few snags stumbling my way through I have resolved quite a few issues, and need help with something new. I am using a TCPIP client/server and I find that at the end of each loop when I am reading the data from the network stream it appends a character to the end. I have tried removing the last character but I am not sure if it is getting the whole character successfully because I still get lots of different errors both in binary and xml deserialization whcih I think is related to this. Does anyone know the ascii code for the termination character for TCPServer/Client communications?
View 15 RepliesI am working on a text-based game and as your character moves, you get informations such as the room name and below, a description (Lorem ipsum in the example) which is an array of string. I would like to know how to append characters to it. I am actually trying to display a minimap made of ASCII character. See the second bloc code for an example.
From:

Into:

The game itself is made in VB.NET but a solution in pseudo-code is also welcomed. Also, each line's length is aproximatively the maximum length it must be.
The desired output must be an array of strings because this data is later send to a client connected using sockets.

I need to split a string at all whitespace, it should ONLY contain the words themselves. How can I do this in vb.net? Tabs, Newlines, etc. must all be split! This has been bugging me for quite a while now, as my syntax highlighter I made completely ignores the first word in each line except for the very first line.
View 4 RepliesI'm having difficulty with some strings of varying 'meaningful' length from a different database (not under my control) that I am trying to trim in my vb.net code.
I only want to remove TRAILING whitespace... therefore, I can't really use .trim method.
The reasoning behind this being that the field sent from the french database usefully uses a <space> to represent a 0 (as you do).
The string is always the same length but the meaningful length can vary, an example being 95WO<space>5CA<space><space><space>...etc
Or it could be this...
<space><space>WO<space><space><space>... etc
Or this...
<space>5WO95CA<space><space><space>...etc
I've got my methods in place to split the string into pairs and perform various lookups but until I can remove the trailing whitespace I'm a bit stuck

View 8 RepliesIs there any way in VB.NET to remove all of the whitespaces between tags in HTML? Say, I've got this:
<tr>

The string I've built is an entire HTML document, and it counts everything before those tags as legitimate space, so I need to trim it out. Is there a reg ex or function out there I could use to do this?
There is an option in Visual Studio (since as far back as I can remember) that allows you to see "Whitespace" in your code. This is often seen in file differential viewers as well.
I'm wondering if anyone knows how this can be accomplished in VB.net (or any other way) so that i could use a similar type of display option in my software.
I have not yet tried to do this but my only first thoughts would be to override the "paint" of the textbox to actually add the little tab "arrows" and space "dots" manually via GDI, or create a texbox control from scratch. Seems to me there could be an easier way to do this.
