Convert Bytes To XML Legal Text?
Aug 8, 2011
I have to store the bytes of a image file inside of an XML file that is read by another program... The problem is, if I inject it as just plain bytes, the end-program has an error (presumably because it contains non-legal XML characters). How can I convert bytes into something that XML can legally read? I really have no other options at this point. I have to inject the image file as bytes (specifically a .bmp file).

I created a text file contains 4 bytes of data
AABBCCDD
I just want to read the first 2 bytes (AABB) to execute it with my program.
Then I'll need to read the last 2 bytes (CCDD) for another computer routines

See where my vb.net equivalent of a working c# assignment statement is not working?
bytes(i / 2) = Convert.ToByte(hex.Substring(i, 1), 16)
Here's the c# followed by the vb.net function.
private byte[] StringToByteArray(String hex)
{
int NumberChars = hex.Length;
byte[] bytes = new byte[NumberChars / 2];
[CODE]...
And the vb.net that is throwing the error within the for loop
Private Function StringToByteArray(ByVal hex As String) As Byte()
Dim NumberChars As Int16 = CShort(hex.Length)
[CODE]...

My app displays the bytes downloaded in a label using:
Private Sub MyDownloader_DownloadedByteCountChanged(ByVal ByteCount As Integer) Handles MyDownloader.DownloadedByteCountChanged
lblDownloaded.Text = ByteCount.ToString()
End Sub
But I thought it would be 'nicer' if it display the amount as kb/mb/gb, etc.

I have a single that might have a decimal place but might not. I have to put the digit before the decimal into the first 4 bytes and the digit after in the next 4 bytes.
So 1.1 would be 01-00-00-00-01-00-00-00
or 2.1 would be 02-00-00-00-01-00-00-00
or 1 would be 01-00-00-00-00-00-00-00
The digit before the decimal point is stored like an integer in bytes the same with the digit after the point. So 1.1 gets split into 1 and 1 and then stored as 2 DWORDS: 01000000 and 01000000

I'm trying to convert standard bytes like so:
00DEAD00BEEF0000
and convert it to base64.
I want it to go from bytes -> Base64.
Not
String -> Base64.

I'm trying to send a 28 character string to a remote ip address and port. I've done this successfully in vb.net using the following code snippets:
Dim swon As String = "A55A6B0550000000FFFBDE0030C8"
Dim sendBytes As [Byte]()
sendBytes = Encoding.ASCII.GetBytes(swon)
netStream.Write(sendBytes, 0, sendBytes.Length)
I now have to convert this across to c++ and have the following so far:
char *swon = "A55A6B0550000000FFFBDE0030C8";
array<Byte>^ sendBuffer = gcnew array<Byte>(bufferSize);
sendBuffer = BitConverter::GetBytes( swon );
tcpStream->Write(sendBuffer, 0, sendBuffer->Length);
but am getting stuck at this point. I'm sure I'm missing a simple syntax error but I can't figure it out!To clarify, I'm not getting an error, but I don't think the string is being converted to bytes correctly as when I convert back, I just get a '01'

I am receiving a data stream which contains 4 bytes of data which need to be converted to a 32-bit float (IEEE 754). This was easy to do in C as I created a union with a 4-byte array and a 32-bit float. Job done. However I have no idea how to accomplish this in VB (pls note I do not code in VB).

Im making a database converter (phpbb to ipb)I noticed during analysing both databases that the posts of phpbb are converted to bytes as you can c here
-- Table structure for phpbb_posts
-- ----------------------------
CREATE TABLE `phpbb_posts` ([code]....
I want to convert those to regular text again but I have no clue how to script my converter to lookup the bytes place (after 0x) converts the string (as the bytes arent in array) and where to stop converting the bytes (after the ,)then replace the bytes text by the regular text and this needs to be in a loop because all posts need to be converted to normal text.

I am working on a project that needs to send hex bytes ie.Sub receives an integer like 276 and then performs
Dim CmdBuf() As Byte = New Byte() {Byte1, Byte2}
strHex = Hex(intNumber) which makes strHex equal to 114 in hex...
Next I need to break into separate bytes something like
Byte1 = Left(strHex, 1)
Byte2 = Right(strHex, 2)
But this does not work......Hex value of 114 needs to be converted into a couple of bytes like &H1 &H14 to be sent out the serial port.
.Write(Buf, 0, 2)
How can I do this?

Is there anyway to convert an image file bytes array into an array of the real RGB values of that image?
I don't really want to use GDI+ or the System.Drawing library, but simply apply a certain calculation/processing to every byte of the image file and get another array that contains the RGB values of every pixel in that image. I know it could be done as I know how to do it in a different programming language (Python) but not in Visual Basic.

The application is working good, i can receive data on port 48888 and i can write it to my logfile, but my problem is when i convert bytes to string. I have the correct data, but all the bufferReadSize is filled with space. Example: if i send only: test, my log file will have test and 4 lines of space only. In my code, right after Dim clientdata As String = Encoding.ASCII.GetString(bytes).
I tried to trim(), replaceI() or any string manipulation, and it's not working!%!? Is there anything i need to do before i can start manipulating that string?

I want it to do is that you input a string, then you select an algorithm (Theres only going to be one RijnDael) then you input a key, then the Initialization Vector comes from "txtIV.text" then you select the key bytes and the block bytes from the numeric up/down, then you either encrypt or decrypt.

Ok i am having some issues designing a base-class to handle generics.Caveat is i need to restrict the type put in as a Numeric type, specifically Int16, Int32, or Int64 (Short or Long).I know you can do Of T as {Structure} but i dont want to select the key bytes and the block bytes from the numeric up/down.

What exactly does this line do?
i = stream.Read(bytes, 0, bytes.Length)
Does it read the entire message string sent by the client? I have a line to write to the stream later in the code and that does not seem to be sending anything back to the client, although the code around is excuting.
i = stream.Read(bytes, 0, bytes.Length)
While (i <> 0)
Try
' Translate data bytes to a ASCII string.

I am having trouble converting the Bytes() to a readable text.
I will be receiving packets from a UDP Connection, but due to lack of connectivity issues, they have provided me a .mem file that i am assuming is the whole stream of the packet.
So for now, i am trying to read the file and i get a collection of bytes(). but i cannot convert it to readable text.
