Parsing a MIME-Message using anmar.SharpMimeTools - c#

I'm trying to parse a MIME-Message, using SharpMimeTools and some sample Mime Messages from Hunny Software. I managed to create a new Message from a file and save the Decoded Body to a file (it's a png-Image), but the created file is corrupted. Mostly the the example file and the one I've exracted look the same, but there are differences.
The files can be found here:
The original Message as a Text-File: m0013.txt
The origninal PNG-Picture: Blueball_original.png
The extracted, corrupted PNG-Picture: Blueball.png
An excerpt of the Hex-View of the files:

42 3f 18 42 3f 18 42 3f 10 39 3f 10 31 3f 00 18
... and finally, this is the code I'm using:
public void MIMETest()
{
FileStream fileStream = new FileStream(#"D:\m0013.txt", FileMode.Open);
SharpMimeMessage m = new SharpMimeMessage(fileStream);
fileStream.Close();
parseMessage(m);
}
public void parseMessage(SharpMimeMessage message)
{
if (message.IsMultipart)
{
foreach (SharpMimeMessage subMessage in message)
{
parseMessage(subMessage);
}
}
else
{
System.IO.File.WriteAllText(#"D:\Extracts\" + message.Name,
message.BodyDecoded, message.Header.Encoding);
}
}
Do you have any suggestions how to solve this problem?


You are writing out binary files using WriteAllText. You cannot expect to write out a PNG using a text writer.
WriteAllText should only be used for text content-types. For other content-types you should use WriteAllBytes.
Also, in your code, you are writing the text using the original text encoding it was transmitted with. You probably want to just use UTF-8 regardless of what the original was.

How to identify encoding of ESC/POS for USB label printer without driver for Mettler Toledo scale

I have a Mettler Toledo UC EVO line scale of which I would like to control the printer with my own program. The scale is a Windows PC based scale with touchscreen, load cell and printer in one.
No dirvers and libraries are provided from Mettler toledo. I have to go find out for myself.
By means of a Mettler test tool that is already installed on the scale and a USB sniffer I was able to intercept the following code:
01 1b 5a 02 1b 4a 03 1b 56 30 04 1b 6c 30 05 1b

Full HEX file
It seems that there are ESC/POS commands in between. And there seems to be a count for every new ESC command.
I have made a C# app where I can control the printer by means of LibUSB. If I use the feedEvoBtn_Click method here, it will be printed by the printer. So there is communication with the printer and my program
public partial class Form1 : Form
{
private UsbDevice _evoLinePrinter;
private UsbEndpointWriter _evoEndpointWriter;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
_evoLinePrinter = UsbDevice.OpenUsbDevice(new UsbDeviceFinder(0x0EB8, 0x300C));
}
private void openEvoBtn_Click(object sender, EventArgs e)
{
try
{
_evoLinePrinter.Open();
IUsbDevice wholeUsbDevice = _evoLinePrinter as IUsbDevice;
if (!ReferenceEquals(wholeUsbDevice, null))
{
wholeUsbDevice.SetConfiguration(1);
wholeUsbDevice.ClaimInterface(0);
}
_evoEndpointWriter = _evoLinePrinter.OpenEndpointWriter(WriteEndpointID.Ep02, EndpointType.Bulk);
eventBox.Items.Add("Open reader/writer evo line");
}
catch (Exception ex)
{
eventBox.Items.Add(ex.Message);
}
}
private void feedEvoBtn_Click(object sender, EventArgs e)
{
try
{
_evoEndpointWriter.Write(new byte[] { 0x01, 0x1b, 0x53 }, 1000, out int outer);
eventBox.Items.Add("Feed evo line printer");
}
catch (Exception ex)
{
eventBox.Items.Add(ex.Message);
}
}
private void testLabelEvoBtn_Click(object sender, EventArgs e)
{
try
{
int lenght;
_evoEndpointWriter.Write(new byte[] { 0x01, 0x1b, 0x5a }, 1000, out lenght);
_evoEndpointWriter.Write(new byte[] { 0x02, 0x1b, 0x4a }, 1000, out lenght);
_evoEndpointWriter.Write(new byte[] { 0x03, 0x1b, 0x56, 0x30 }, 1000, out lenght);
_evoEndpointWriter.Write(new byte[] { 0x04, 0x1b, 0x6c, 0x30 }, 1000, out lenght);
_evoEndpointWriter.Write(new byte[] { 0x05, 0x1b, 0x4d, 0x30 }, 1000, out lenght);
_evoEndpointWriter.Write(new byte[] { 0x06, 0x1b, 0x4a }, 1000, out lenght);
_evoEndpointWriter.Write(new byte[] { 0x07, 0x1b, 0x5a }, 1000, out lenght);
_evoEndpointWriter.Write(new byte[] { 0x08, 0x1b, 0x57, 0x34, 0x33, 0x32, 0x30, 0x34, 0x38, 0x30 }, 1000, out lenght);
_evoEndpointWriter.Write(new byte[] { 0x09, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, }, 1000, out lenght);
_evoEndpointWriter.Write(Encoding.UTF8.GetBytes("Line one\n\rline two\n\r"), 1000, out lenght);
eventBox.Items.Add("Print test label evo line printer");
}
catch (Exception ex)
{
eventBox.Items.Add(ex.Message);
}
}
}
Nothing happens without putting the count before the feed command.
The printer is probably controlled by ESC/P commands. Only I can't manage to just print a standard text.
When I use the testLabelEvoBtn_Click method, something happens to the printer, and after a few clicks a label comes out. There is just no text to be seen. This method does the same as the test tool, only with its own text in it. This produces the following result in the usb sniffer
The result of using testLabelEvoBtn
When I look at the HEX code sent from Mettler's test tool, I also don't see that this is sent to the printer as ASCII, while my own program does.
Can anyone explain to me what this encoding is that the test tool sends to the printer? I hope that this way I can control the printer myself with text, a barcode and possibly a logo.
Thanks

Looking at your hex trace, the commands don't seem to match any usual ESC/POS standard:
01 1B 5A [ESC Z]
02 1B 4A [ESC J]
03 1B 56 30 [ESC V 0]
04 1B 6C 30 [ESC l 0]
05 1B 4D 30 [ESC M 0]
06 1B 4A [ESC J]
07 1B 5A [ESC Z]
08 1B 5A [ESC Z]
09 1B 57 34333230343830 .. [ESC W "4320480" ...]
However, the last one seems to be your actual print data - as a bitmap image, not as text.
The initial 7 ASCII numbers problably indicate 432 dots/pixel width and (0)480 lines height.
And then every bit of the following bytes are one dot/pixel - although it seems the line direction is mirrored/reversed.
I'm not a C# programmer, but this tiny bit of Ruby produces an image from your hex (part after the ASCII width/heigh info in bitmap):
width_bytes = width/8
(0..height).each do |line|
line_bytes = bitmap[line*width_bytes, width_bytes].unpack('C*')
line_bytes.reverse.each do |byte|
print byte.to_s(2).gsub("0"," ").rjust(8).reverse
end
print "\n"
end
Some parts of the output (scroll right):
1111111 1111 111
1111111 1111 111
1111111 11 1111 111 111111

Getting usable data from proprietary-what-looks-like C# data file?

I have output from a SRSLabs EC301 in .sec format, which is a proprietary binary format. There is some windows based software available for reading this file, but someone moved the tower which has the software I need, and while I am still trying to find it, I'm also parallelizing my search for getting useful data out of this file.
I've viewed the file with hexdump and get this:

And so on. The output viewed as ASCII looks eerily like Java, so my question is: is this possibly some standard .NET pickle-like output that can be fairly easily loaded into a Java program to be read?
There are classes that aren't part of the .NET standard library, but I also decompressed the MSI installer and see some names I recognize, and believe them to be bytecode files.

How to fix Issue with convert Base64 to byte from GPS & Fingerprint data compare?

How to compare both with byte array??
Finger print code required to Convert FromBase64 string to Byte and GPS code required to Hex to byte..
I am getting different array size from Finger print it returning 512 byte array and from GPS it comes 256 byte array..
below is my code form C#
Create demo aspx page and check it.
I have added Demo project here.
you can download and check it..

Thanks

I have been resolved issue by converting HEX Code string to Byte[] and
USB reader value convert fromBase64 string then Byte[]
I have created below method to Compare both with byte[],
below fpengine is the thirdparty COM Object that will use for compare finger scanned value with finger point algorithm.
public bool IsMatchFound(string HexCodeString , string USBReaderString)
{
try
{
int scope = 0, intdisc=0;
byte[] gmat = HexEncoding.GetBytes(HexCodeString, out intdisc); //StringToByteArray(str1);
byte[] gref = Convert.FromBase64String(USBReaderString);
scope = fpengine.MatchTemplate(gmat, gref);
return (scope > 30) ? true : false;
}
catch (Exception ex)
{
return false;
}
}
Let me know if anybody want help same kind of application..

C# Append byte array to beginning of a file (without loading entire file in memory)

Question: Is it possible (and how?) to append a byte array to an existing file without loading the entire file in memory.
To be more specific:
the goal is to do transform this:

I've been trying to figure this out the whole morning, but I can't seem to find a working solution.
I know it is possible to append a file at the end without loading the file into memory, but I need to append the beginning.
Thanks in advance

Simply put, that's not possible. That's not how files work. Depending on how you do it, you may not have to load the whole file into memory at the same time, but you will need to load every single byte of the file and write it after the bytes you wrote to the front.

Remove Hexa without char in each line

I have data in the form of from TextBox1
00 00 00 4E FF 53 4D 42 25 00 00 00 00 18 01 28 ...N.SMB%......(
00 00 00 00 00 00 00 00 00 00 00 00 00 08 12 8B ................
01 08 7E 31 11 00 00 05 00 00 00 00 00 00 00 02 ..~1............
and I tried to change it to be like this on the result TextBox2
...N.SMB%......(
................
..~1............
I've tried the function *. remove but only the first row are deleted but the second line and so on are not deleted. Can anybody help me?
i use this code
string test = rtText1.Text;
rtText2.Text = test.Remove(0, 48);
and then this result rtText2
...N.SMB%......(
00 00 00 00 00 00 00 00 00 00 00 00 00 08 12 8B ................
01 08 7E 31 11 00 00 05 00 00 00 00 00 00 00 02 ..~1............
how can I make a command "test.Remove (0, 48);" can be done on each line? or is there another function?

It's hard to say exactly what you need based on what you've posted, but a regex may work well here:
TextBox2.Text = System.Text.RegularExpressions.Regex.Replace(
TextBox1.Text,
#"^.{49}",
"",
RegexOptions.Multiline );
This will simply replace the first 49 characters of each line with an empty string.

It looks to me as though you're trying to remove the hexadecimal representation of whatever string is on the right.
This did the trick for me:
// Initial data
string Data = #"00 00 00 4E FF 53 4D 42 25 00 00 00 00 18 01 28 ...N.SMB%......(
00 00 00 00 00 00 00 00 00 00 00 00 00 08 12 8B ................
01 08 7E 31 11 00 00 05 00 00 00 00 00 00 00 02 ..~1............";
// An array containing each line of data
string[] lines = Data.Split('\n');
Data = "";
// Loop for each line, removing each "byte" + it's space, plus the trailing space
for (int i = 0; i < lines.Length; i++)
{
Data += lines[i].Remove(0, (3 * 16) + 1);
if (i != lines.Length - 1)
Data += "\r\n";
}
Console.Write(Data);
And here is the output:
...N.SMB%......(
................
..~1............
