Newline after receiving "AA" on Windows Application Form

sumit Kale

Hello,

I am designing a Protocol Data analyzer in c# by using Windows application Form. I am receiving data at speed of 5.25 Mbps from COM Port & i want to show this data over Windows Application.

So now i am able to get data over window. However i want to split string to newline & show the time as soon as i get "AA" (AA is my Preamble in protocol Header).

My Protocol data stream is as mentione below:

AA 01 00 13 59 A1 02 61 6A A1 02 61 09 00 01 81 00 01 9B D3 32 72 23 AA

I have attached my source file.

So how i can do this? Any suggstions?

ok you got the solution
but before you were using StringBuilder now why did use buffer?
sumit Kale9y ago
Solved by using following Line:

Log(LogMsgType.Incoming, string.Format("Sniffer Logged in {0}\n\r", DateTime.Now) + ByteArrayToHexString(buffer).Replace("AA","\nAA") + string.Format("\n\r")); // Show the user incoming data in Hex format & after each 10 second update the data coming & post it on the newline

Hey not yet.

I am still trying.

The method which you suggested still firing execption. So i am trying to check how i can remove it
Rafnas T P9y ago
have you got the output
sumit Kale9y ago
After removing label no change in the error status.

Still its firing error
Rafnas T P9y ago
remove the label and try
sumit Kale9y ago
Using wordwrap= false; its firing error.

About label also its firing error.

Do i need to change my design?
Rafnas T P9y ago
you can use richtexbox itself
but yo have to make word wrap=false

sb = sb.Replace("AA", "\nAA");
richTextBox1.WordWrap = false;
richTextBox1.Multiline = true;
richTextBox1.Text = sb.ToString();

Ok. Changes gave me exception mentioned as below:

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

I have attached my design
Rafnas T P9y ago
add label give name as lbl or Text box and try as below

sb = sb.Replace("AA", "\nAA");
lbl.Text = sb.ToString();

I got the result as follows
sumit Kale9y ago
After using sb= sb.Replace("AA", "\nAA");

Result Window:

Sniffer Logged in 05.05.2017 11:37:49
E6 67 0F A2 FE 67 0F A2 0C 02 00 81 00 0D 00 00 00 DE 7B D6 39 DF AA 01 00 13 74 68 0F A2 86 68 0F A2 09 00 01 81 00 01 9B D3 32 72 9A AA 01 00 13 9D 68 0F A2 B3 68 0F A2 0B 01 00 81 00 0D
Rafnas T P9y ago
then how you are getting result now

when you use

sb= sb.Replace("AA", "\nAA");

This is what i am receiving after doing suggested changes:-

Sniffer Logged in 05.05.2017 11:27:40
00 81 00 0D 00 00 00 DE 7B D6 39 C3 AA 01 00 13 E1 EE C0 7D F2 EE C0 7D 09 00 01 81 00 01 9B D3 32 72 1D AA 01 00 13 0A EF C0 7D 20 EF C0 7D 0B 01 00 81 00 0D 00 00 C5 BA B5 82 71 AA 01 00

What i want to get should be :

Sniffer Logged in 05.05.2017 11:27:40

00 81 00 0D 00 00 00 DE 7B D6 39 C3
AA 01 00 13 E1 EE C0 7D F2 EE C0 7D 09 00 01 81 00 01 9B D3 32 72 1D
AA 01 00 13 0A EF C0 7D 20 EF C0 7D 0B 01 00 81 00 0D 00 00 C5 BA B5 82 71
AA 01 00

private string ByteArrayToHexString(byte[] data)
{
StringBuilder sb = new StringBuilder(data.Length * 3 );
foreach (byte b in data)
sb.Append(Convert.ToString(b, 16).PadLeft(2, '0').PadRight(3, ' '));

sb=sb.Replace("AA","\nAA");

return sb.ToString().ToUpper();
}

try this its working perfectly here
Rafnas T P9y ago
or try this

sb= sb.Replace("AA", "\nAA");
sumit Kale9y ago
Basically its printing same result which was my doubt.

I want to put string starting from AA to next line till it receive another AA.

Ex:

AA xx xx xx xx xx xx xx xx

AA xx xx xx xx xx xx xx xx
Rafnas T P9y ago
ok try giving only
sb.ToString().Replace("AA", "\nAA");

private string ByteArrayToHexString(byte[] data)
{
StringBuilder sb = new StringBuilder(data.Length * 3 );
foreach (byte b in data)
sb.Append(Convert.ToString(b, 16).PadLeft(2, '0').PadRight(3, ' '));
//sb=sb.ToString().Split("AA");
sb.ToString().Replace("AA","\nAA");
//sb.Append("\n AA");
//sb=sb.Append(string.Format("AA{0}AA", Environment.NewLine));
return sb.ToString().ToUpper();
}

Hello Rafnas T P,

I tried to do by your method. However its showing me error:

"Cannot implicitly convert type "string" to "system.Text.StringBuilder" ".
Rafnas T P9y ago
private string ByteArrayToHexString(byte[] data)
{
StringBuilder sb = new StringBuilder(data.Length * 3 );
foreach (byte b in data)
sb.Append(Convert.ToString(b, 16).PadLeft(2, '0').PadRight(3, ' '));
//sb=sb.ToString().Split("AA");
sb=sb.ToString().Replace("AA","\nAA");
//sb.Append("\n AA");
//sb=sb.Append(string.Format("AA{0}AA", Environment.NewLine));
return sb.ToString().ToUpper();
}
Rafnas T P9y ago
if you wanted to come next line then try as below

sb=sb.ToString().Replace("AA","\nAA");

if you wanted to split then try as below

sb=sb.ToString().Split("AA");
