I open the serial port and using a recieved data sub, pull data out of the input buffer.I then place the data on a textbox. Problem is, all I seem to get is "????xx??" of various different lenghts.How can I re-encode the data as ascii?
With SerialPort1
.ParityReplace = &H3B ' replace ";" when parity error occurs
.BaudRate = 9600
.Parity = IO.Ports.Parity.None
[code]....
Say only &, ?, /,.
I want the rest to remain intact, including chinese or japanese characters. Those can be inserted into get just fine right?

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:

The TextFieldParser is returning

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'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

I found VB to be the easiest and best tool to process ascii data. I have a bunch of them (about 15), each is constructed differently, and I will receive monthly updates. the data is all the US flight navigation systems, like VORs, airports...etc. Some of the files have comments and explanations on top and bottom only, and the rest is heading and data at specific columns. Others are a little trickier, like the data for Jetways, its not continuous data, but it breaks for each jetway to identify it first, then plot the data in rows. What am ultimately trying to do is create a tabular version of some sort of this data to be used in my GIS database. Some of the fields needs to be combined ofcourse, like the latitude and longitude data is given in separate columns, but they need to be combined. I have pasted below a small sample of two different data files. [code]
View 5 RepliesI have data that has to be collected from my database and sent to a supplier's edi system. The file has to be in ascii format so their system can read it. I am writing what I see as an ascii format file but they say it's in edibc format when they receive it. I am posting my code and hopefully somebody here can help me out. Funny thing is that I have done this before successfully and am using virtually the same code but to no avail!!

I have made an application in VB 6.0.In this application ,i am connecting one controller through serial port to laptop.I have used MSOMM control for this purpose.Controller is sending data as a string .On VB 6.0 applicaton in laptop ,i am getting data displayed in one text boxall in ASCII code/characters.Total chatacters in string are 61.My problem is this that all 61 characters are comming in one text box.I want thateach character should come in seperate text box so that i can be able to display them individually,i.e. 61 characters and 61 text boxes.
View 2 RepliesIf we have a string that contains for example "01_1A" in ascii, I would like to take first two chars and following two chars after mark and send it as hex format, like &H1 and &H1A.
Note that I would not convert ascii to hex. I am asking for something like &H(var).
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 RepliesWe have the customers credit card number on file which we use simply to identify them when they swipe at our computer. The problem i'm running into is that when they swipe their card in the card reader (Magtek mini usb) it outputs the data as ASCII which looks something like %B followed by the credit card number in whatever textbox i have the program focused on. I'm sure i could just search the textbox for any 16 character number string and assume that is their card number, but i was just curious if there is some best practice to decript the ASCII output from the magnetic card reader.
View 1 RepliesSo 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 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.
View 1 RepliesI 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}

I need to write an application for receiving data (ascii characters) from microcontroller through the serial port in three separate parts. I've created three RichTextBoxes, but I do not know which commands I need to type. In first textbox I need to receive one byte... next six bytes need to be placed in second text box, and finally last seven bytes need to be placed in third textbox.

I have a call to Server.URLEncode(string) from an old asp file that stores user input into a table. In this case it was a string of Chinese charters.
The actual data is :
%E8%B0%B7%E6%AD%8C%E7%9A%84%E5%89%8D%E6%99%AF%E9%BA%A6%E5%85%8B%E6%96%AF%E9%9F%A6
I rewrote the code to vb.Net and after I get the data from the table, I call
HttpContext.Current.Server.UrlDecode(string) to decode the string, add it existing mark up for an email and send it on its way.
Note that with Visual Studio i can see the HTML markup as it appears in the email, and ALL of the Chinese data is EXACTLY as I would expect it.
When the emial is received i get "???????????" characters where there should be the Chinese characters.
What I do not understand:
What Server.URLEncode actually encodes the data to. It appears to be HEX.
What the array of "?" means in outlook or any other email system that opens it, I assume it means "Hey i cant convert this stuff, so here is a question mark for kicks, good luck."
I am trying to write a function which has the ability to decode a string from utf8. I am getting the string as a response from a webserver.I am using the following line to do the decoding:
DecodeReply += System.Text.Encoding.ASCII.GetString(System.Text.Encoding.UTF8.GetBytes(temparray(i).ToString))
