i have a text file that orignated on an IBM mainFrame. the file contains numeric data as follows:
00439N.
The above value should be -04395. I'm having problems making this conversion happen are there anu methods in the framework
I working with some EBCDIC data that I need to parse and find some Hex values. The problem that I'm having is that it appears that I'm reading the file in with the incorrect encoding. I can see that my record begins with "!" (which is a x5A in EBCDIC) but when doing the conversion to hex it returns as a x21, which is the ASCII value for a "!".
I was hoping that there was a built-in method in the framework, but I'm afraid that I'm going to have to create a custom class to correctly map the EBCDIC character set.
Using fileInStream As New FileStream(inputFile, FileMode.Open, FileAccess.Read)
Using bufferedInStream As New BufferedStream(fileInStream)
Using reader As New StreamReader(bufferedInStream, Encoding.GetEncoding(37))

I want to convert £Ë†â€°¢â€°¢¤£â€ ø which is in EBCDIC to UTF8 string, which is thisisutf8 You can use the above link to test.
I refered the below article on how to read EBCDIC data in .net

Then I used the same method to read the ebcdic data
Dim encoding As System.Text.Encoding = _
System.Text.Encoding.GetEncoding(37)
However I am not getting the expected data
Here is my code, to get the result into a atring, a.
Dim a As String = System.Text.Encoding.UTF8.GetString(System.Text.Encoding.GetEncoding(37).GetBytes("£Ë†â€°¢â€°¢¤£â€ ø"))
Here's my code and the result, as much as I know, is in ASCII:

I need the data to be in Hex
This has been driving me crazy for two weeks! I just started learning Vb.net, so please forgive me if I make rookie mistakes. Basically, I would like to convert any type of file to Ascii code. An mp3, .wav, .avi etc. The most I was able to do is convert only the first character of the file to Ascii. Also, I'm not sure what would be the fastest method to do this. SteamReader, FileStream, or BinaryReader. Can anyone explain what method would be best? This is what I have so far:

View 2 RepliesI'm testing a "simple" login program: it has predetermined ID and Password, after input is correct then you can change the ID and Password. 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).

i thought it was the for loop problem...since i will go up to 7 while len(hexnum) is 8 so it would loop again but there is nothing after 8th HEX?so i tried For i = 1 To Len(hexnum)-1 Step 2 ...this time...textbox didnt show anything...+ the same error came up...

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?
I am trying to make a simple program to convert ascii in its code format
Example: Chr(53) & Chr(53) & Chr(54) & Chr(100) & Chr(52)

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
? 3
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.
