String Encoding And File Writing

Oct 16, 2011

I have a long UTF8 encoded text string. The actual values stored in the string are hexadecimal. I want to convert the encoding and save to a binary file.

Is there a simple encoding.convert or other method to do this with?

Basically the output is twice as large as it needs to be right now. The long way of doing it would be a routine to go through the string two characters at a time and convert to byte array and then .writeallbytes I guess. It seems there must be a simpler way of converting this?

Overwriting The String While Writing On Text File?

Jan 15, 2012

I have written a program which reads the text from the text file cleans it for some specific letters or phrases and then saves it in another text file. I am having a problem in rewriting the processed or cleaned data (after it has removed some phrases and characters)onto writing the file.

I have successfully written the text on the file except one problem. In each loop when each string is cleaned and is written on the text file, it overwrites the previous string. What I want is that it should write in the next line or in the same line.

My code is given below:
Private Sub btnopen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnopen.Click
FileOpen.Title = "Please select the file"

[Code]...

how can I write the text in the new line and avoid overwriting of text in my text file.

C# - Writing String To A File Is Generating Unexpected Content?

Apr 11, 2012

I've two Strings which I'm loading from a SQL Server 2008 database (nvarchar-field)After loading them from the database Visual Studio 2010 displays them as follows in the watch window:

str1 = "Test"
str2 = "Test"

But the comparison with str1 = str2 returns False If I write those strings to a file with UTF8 Encoding the result is as expected:

Test
Test

If I write those strings to a file with ANSI (Default) Encoding the result is NOT as expected:

?Test
Test

Converting the strings to bytes:

System.Text.Encoding.Default.GetBytes(str1) 'Returns ByteArray {63, 84, 101, 115, 116}
System.Text.Encoding.Default.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str1) 'Returns ByteArray {239, 187, 191, 84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}

Where is the Byte 63 in case of ANSI Encoding OR Bytes 239, 187, 191 in case of UTF8 Encoding for str1 coming from?Well, Bytes 239, 187, 191 are the BOM for UTF8. The question here would more likely be: Why do I get the BOM for str1 but not for str2?(Well, the values are values passed to a webservice which inserts them into the database, the initial values are passed to this webservice by a client I've no control over)

VS 2010 : Set The Last Position Of String When Writing To Text File?

Sep 16, 2011

I'm outputting a number of variables to a text file and each field needs to be in a specific place.For example:I have a string that is varying in length, but will never be more than 5 characters. The string has to end on the 8th character of the line. Is there a way to write the string to ensure that the string ends at a specific place on the line, regardless of the length?

Javascript - Encoding String For Apostrophe In Asp.net?

Sep 20, 2011

I am having a problem trying to resolve an apostrophe related issue. I have searched SO,

My clientside javascript code is: var strUserText = uSettings.replace(/'/g, "&apos;")

after the above line is executed, the form does a submit

document.form1.submit(); in code behind, a class retreives those values:

sUserSettings = request.form("strUserSettings ") the result is a semi-truncated string.Given the above code process flow, how can I save "John O'Brady's ASP Blog" in to a database?

I thought I was saving "John O'Brady's ASP Blog" but that isn't working.

I used WriteAllText to set the encoding for a text file. When I wrote it, everything worked out fine. However, strange characters or symbols appeared in some ofm y fields without my having typed it. why is this so? The encoding I'm using is UTF8. I used the WriteAllText to write the fields to file but did not use the ReadAllText to bring the data back into the fields or program.

Find A Log File Encoding And Understand It's Structure

Oct 14, 2011

My questions isn't really about a programming language but, since I did not find a general programming forum, I chose this one as I know VB.Net. There's this game, that you might already know, which is called Star Wars Galaxies (And is ending soon actually .. ). For each account and character, the game automatically saves chat logs in a .cht file. A player can have multiple chat channels that have different chat filters (group chat, public chat, etc) and they are all saved in this file. I'm thinking they are probably separated by some kind of a "flag" for the game to be able to detect them.

Encoding Array.String > Array VB2005

May 27, 2009

I've been working with a sig capture application sample on a windows mobile device, The data is sent via IP to a host as a byte array and is then drawn onto the screen of the host as it appeared on the client. I was able to get this into the form of a bitmap object so I could print it or save to a jpg file. That all works well. The problem now is that I need to store this data in a database and then be able to recall it at a later time and recreate the signature image.

The byte array data is much smaller than the actual image so I would like to store it in that form. My issue is that when I convert this byte array into a string and back again my program can no longer re-create the image. Once I saw the problem I created the code below as a test and added the msgboxes to get an idea what was happened to my data.
