Remove Hexa without char in each line - c#

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%......(

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
4d 30 06 1b 4a 07 1b 5a 08 1b 5a 09 1b 57 34 33
32 30 34 38 30 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

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

Cannot interpret state of this BitVector32

I am debugging some code right now (VS 2019, .NET Framework 4.7.2), stopped at a breakpoint, using the Immediate Window to evaluate variables. I have a BitVector32 which I am not understanding its state. Here is the content of the IW:
stillInHand.ToString()
"BitVector32{00000000000000000000000000001100}"
stillInHand
{BitVector32{00000000000000000000000000001100}}
Data: 12
stillInHand[0]
true
stillInHand[1]
false
stillInHand[2]
false
stillInHand[3]
false
stillInHand[4]
true
stillInHand[5]
false
stillInHand[6]
false
stillInHand[7]
false
There have been no calls to any of the Create* methods, and stillInHand was created with the BitVector32(Int32) ctor. Shouldn't indices 2 & 3 be true and all the rest be false?

Actually, this issue is related to the understanding of the index of BitVector32[ ].
First of all, stillInHand[1] doesn’t mean to get the second bit of stillInHand(BitVector32). It represents this action: use 00 00 … 00 01 to perform &(AND) operation with stillInHand(BitVector32).
For an example: stillInHand(BitVector32) is 00 00 00 00 00 … 00 00 00 11 00, and 1 is 00 00 00 00 00 … 00 00 00 00 01. Then perform &(AND) operation.
00 00 00 00 00 … 00 00 00 11 00 12 &(AND)
00 00 00 00 00 … 00 00 00 00 01 `1`
--------------------------------------------
00 00 00 00 00 … 00 00 00 00 00
And you can see that the last bit(focus on the index value 1) changes from 1 to 0, so the result will be false, if you output or see the result of stillInHand[1].
So, for stillInHand[2], you can see
00 00 00 00 00 … 00 00 00 11 00 12 &(AND)
00 00 00 00 00 … 00 00 00 00 10 2
--------------------------------------------
00 00 00 00 00 … 00 00 00 00 00
The second to last bit(focus on the index value 2) changes from 1 to 0, so the result will be false too.
And for stillInHand[8], you can see
00 00 00 00 00 … 00 00 00 11 00 12 &(AND)
00 00 00 00 00 … 00 00 00 10 00 8
--------------------------------------------
00 00 00 00 00 … 00 00 00 10 00
The fourth to last bit(focus on the index value 8) doesn’t change and it remains as 1, so the result will be true.
Actually, if you analyze the source code from here: Reference Source, you can see these codes:
/// <devdoc>
/// <para>Gets or sets a value indicating whether all the specified bits are set.</para>
/// </devdoc>
public bool this[int bit] {
get {
return (data & bit) == (uint)bit;
//clear other bits (to 0) through the AND operation of the data and mask.
//If the result of the operation is equal to the mask, return true.
//Otherwisse, return false.
}
set {
if (value) {
data |= (uint)bit;
//data = data OR mask, set the specified bit to “1”
}
else {
data &= ~(uint)bit;
//data = data AND ~mask, set the specified bit to “0”
}
}
}
Of course, you can consider it as mask, and this will be easy to understand.

Getting weird question marks after decoding UTF-16-encoded hex bytes

I'm reading a hex byte array from a file using an instance of the BinaryReader class, and I need to decode it from UTF-16. From what I know, I need to do this using System.Text.Encoding.Unicode.GetString(byte[] array).
This is what my code looks like:
public static string ReadHex(string path, Int32 startOffset, Int32 endOffset, bool decode, bool utf16)
{
if (!File.Exists(path))
{
throw new FileNotFoundException($"Could not find a file in path {path}");
}
string result = "";
List<byte> bytes = new List<byte>();
BinaryReader br = new BinaryReader(File.OpenRead(path));
for (int i = startOffset; i < endOffset; i++)
{
br.BaseStream.Position = i;
bytes.Add(br.ReadByte());
}
br.Close();
if (decode && utf16)
{
result = System.Text.Encoding.Unicode.GetString(bytes.ToArray());
}
else if (decode)
{
result = System.Text.Encoding.UTF8.GetString(bytes.ToArray());
}
else
{
foreach (byte b in bytes)
{
result += b.ToString("X2");
}
}
return result;
}
It reads the given hex offsets provided by the parameters and decodes them if wanted. The UTF-8 part works perfectly, giving me valid decoded strings. But my issue is with the UTF-16 part.
This is the data that is read from the file:
4D 00 6F 00 6A 00 61 00 6E 00 67 00 20 00 41 00 42
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00
In theory, this is what should be outputted:
Mojang AB
It kinda works, but with one oddity, this is what is outputted when writing the string that the method returns:
Mojang AB ?
These question marks appear on anything that's UTF-16 I put into the method. I don't understand why they appear, as the data that was passed into System.Text.Encoding.Unicode.GetString(byte[] array) does not contain anything past the string it's supposed to contain, and is made up of zeroes (00). Anyone have an idea on why this is happening?

Generating byte of string in with specific size

I have this code which generate 80 bytes of word 'Administrator' to bellow output.
szOperatorName = BitConverter.ToString(data, 45, data.Length - 45); //szOperatorName is set to 'Administrator'
byte[] OperatorName = new byte[80];
Array.Copy(Encoding.ASCII.GetBytes(szOperatorName), OperatorName, System.Math.Min(80,szOperatorName.Length));
OUTPUT
41 64 6D 69 6E 69 73 74 72 61 74 6F 72 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
EXPECTED OUTPUT
41 00 64 00 6d 00 69 00 6e 00 69 00 73 00 74 00 72 00 61 00 74 00 6f 00 72 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
I have highlighted some of main deference between two, any help on getting expected result will be much appreciated

To get expected output use Unicode encoding to get bytes
Encoding.Unicode.GetBytes(szOperatorName)
Test
byte[] bytes = System.Text.Encoding.Unicode.GetBytes("Administrator");
foreach (var b in bytes)
Console.WriteLine(b);
. . . .
Array.Copy(bytes, newArr, bytes.Length);
your current output is based on ASCII encoding (obviously)

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..
