I ve the following stream but I don't know its encoding type because the stream reader detects encoding from byte order marks
Dim reader As StreamReader = New StreamReader(respStream, True)
so how can I detect the encoding type AND convert it to another type? (for ex. from ASCII to UTF8)
PS: What is the difference with the following line?
Dim reader As StreamReader = New StreamReader(respStream,
Encoding.ASCII, True)
I want to write text to a program, it contains a symbol in it for alpha. My text file will not write to a file when I click save. How do I set the encoding type so that it will write this character to file or convert it? They are all symbols that are used in statistics?

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?

View 6 RepliesI 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.
View 2 RepliesMy 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.

if we don't mention the decoding what decoding will they use?I do not think it's System.Text.Encoding.Default. Things work well if I EXPLICITLY put System.Text.Encoding.Default but things go wrong when I live that empty.So this doesn't work well

System.IO.File.WriteAllText("test4.txt", b)

What resources I need to look for, to generate one png image out of three? Since there are sprite generators out there, that do not do what I want, I wanted to try by myself. The user interface should not be the problem, but i have no experience of generating bitmaps, especially those with transparent backgrounds. I will do that in .net. Let´s say I have 6 png files. I want to put them into one image, where there will be two rows of images in it, so 3 in row, 2 in height, 3*2. Every image might have a little different sizes, so i would need to fill up the space with, um, nothing..

View 2 RepliesI'm working with some very large files residing on P2 (Panasonic) cards. Part of the process we employ is to first generate a checksum of the file we are going to copy, then copy the file, then run a checksum on the file to confirm that it copied OK. The problem is, is that files are large (70 GB+) and take a long time to complete. It's an issue since we will eventually be dealing with thousands of these files.
I would like to find a faster way to generate the checksum other than using the System.Security.Cryptography.MD5CryptoServiceProvider I don't care if this means using a specialized hardware card, provided it works and is not to ungodly expensive. I would prefer to have a method of encoding that provided some feedback as to how far the process has gone along so I can display it like I do now.
The application is written in vb.net. I would prefer to be able to use it as component, library, reference within my application, but I'm willing to call an outside application if there is enough improvement in the speed of generating the checksum.
Needless to say, the checksum must be consistent and correct.
in vb.net while entering a new entry i want to assign a record a unique id like in case of numeric i do this way

in this case m using itemid as a unique id and the format is 1,2,3... and m finding out the max and assigning to a new record but how to assign if the previous id is of the a00001,a00002,a00003,a00004...so on. how i do i produce a unique id in this case

2) property name
3) data type
4) get method (checkbox)

3) The DataTypes generate by ORM's LLBLgen/EF/nHibernate
