Have tried some of the online references as wells as unix time form at etc. but none of these seem to work. See the examples below.
running Mysql 5.5.5 in ubuntu. innodb engine.
nothing is custom. This is using a built in datetime function.
Here are some examples with the 6 byte hex string and the decoded message below. We are looking for the decoding algorithm. i.e.how to turn the 6 byte hex string into the correct date/time. The algorithm must work correctly on the examples below. The right most byte seems to indicate difference in seconds correctly for small small differences in time between records. i.e. we show an example with 14 sec difference.

I am trying to read dtc codes using following procedure:
1 - send 0101 which means get the number of the dtc codes
receive - 41 01 82 07 61 01 which means I have 2 trouble codes
2 - send 0x03 to receive codes and
receive - 43 01 33 03 01 00 00 which are the 2 codes : P0133 and P0301
Using a diagnostic service tester I get 5 codes on the same car: P0133, P0301 (the ones I get also) and P0303, P0300 and C1513
How can I see the other 3 codes using my OBD?
Here are pictures with the tester:
You might have multiple OBD2-conform ECUs in your car. To access these, use broadcast addressing or query each and every one separately by adjusting your arbitration ids.
That said, some readers may also show pending (0x07) or permanent (0x0A) DTCs.
Currently trying to essentially reverse engineer a file format that is produced by a CNC machine when backing up programs on the machine so that i can read the programs on a standard PC. Have opened a few of the backup files created and can clearly see patterns of data such as the program name etc. which can be clearly seen in plaintext form. One thing i am struggling with is how numbers are represented in this.
for Example: the number '20' is represented in this file in hex form as '40 0D 03 00'.
More examples:
"-213.6287": "21 67 DF FF"
"-500.3366": "9A A7 B3 FF"
Any help with trying to figure out how these hex values make up those numbers?
Thanks
These numbers are stored as little-endian signed integers, as a count of ten-thousandths.
for Example: the number '20' is represented in this file in hex form as '40 0D 03 00'.
0x00030d40 = 200000.
"-213.6287": "21 67 DF FF"
0xffdf6721 = -2136287.
"-500.3366": "9A A7 B3 FF"
0xffb3a79a = -5003366.
I have a trivial RGB file saved as TIFF in Photoshop, 1000 or so pixels wide. The first row consists of 3 pixels all of which are hex 4B red, B0 green, 78 blue, and the rest of the row white.
The strip is LZW-encoded and the initial bytes of the strip are:
80 12 D6 07 80 04 16 0C B4 27 A1 E0 D0 B8 64 36 ... (actually only the first 7 or so bytes are significant to my question.)
In 9-bit segments this is:
100000000 001001011 010110000 001111000 000000000 100000101 100000110 ...
(0x100) (0x4B) (0xB0) (0x78) (0x00) (0x105) (0x106)
From what I understand 256 (0x100) is a reset code, but why is the first extended code after that 261 (0x105) instead of 257? I would expect whatever dictionary entry this points to to be the 4B/B0 pair for the second pixel (which it may well be), but how would the decompression algorithm know to place 4B/B0 at 261 instead of 257? Can someone explain what I'm missing here? Might there be something elsewhere in the .tif file that would indicate this? Thanks very much.

Let's see
256 (100h) is Clear
257 (101h) is EOF
in your case, then
4Bh B0h is 258 (102h)
B0h 78h is 259 (103h)
78h 00h is 260 (104h)
00h 00h is 261 (105h)
Looks good to me. LZW can actually encode one character ahead of what's been added to the table.
I'm using the crypto module to create salts and hashes for storage in my database. I'm using SHA-512, if that's relevant.
What I have is a 64 byte salt, presently in the form of a "SlowBuffer", created by crypto.randomBytes(64, . . .). Example:
<SlowBuffer 91 0d e9 23 c0 8e 8c 32 5c d6 0b 1e 2c f0 30 0c 17 95 5c c3 95 41 fd 1e e7 6f 6e f0 19 b6 34 1a d0 51 d3 b2 8d 32 2d b8 cd be c8 92 e3 e5 48 93 f6 a7 81 ...>
I also have a 64-byte hash that is currently a string. Example:
'de4c2ff99fb34242646a324885db79ca9ef82a5f4b36c657b83ecf6931c008de87b6daf99a1c46336f36687d0ab1fc9b91f5bc07e7c3913bec3844993fd2fbad'
In my database, I have two fields, called passhash and passsalt, which are binary(64)s.
I'm using the mysql module (require('mysql')) to add the row. How can I include the binaries for insertion?
First of all, I'm no longer using the mysql module, but the mysql2 module (because it supports prepared statements). This changes roughly nothing about the question, but I'd like to mention that those reading this who are using 'mysql' should probably use 'mysql2'.
Second, both of these modules can take Buffers as parameters for these fields. This works perfectly. To do what I was originally attempting to do, I have it like this:
var hash; //Pretend initialized as a 64-bit buffer
var salt; //" "
connection.query('insert into users set?', {..., passhash: hash, passsalt: salt,..., callback});
Additionally, I didn't realize that the crypto "digest" function had a default behavior with no parameter, which is to return as a Buffer.
This is not the best worded answer, but that's because no one seems to be paying much attention to this question, and it was my question. :) If you would like more clarification, feel free to comment.
I need to extract this specific JSON-field into a parameter for my performance test in Visual Studio:
"ExamAnswerId": "757a3735-e626-412b-934c-e577c6963d51"
the problem occurs when I try to do this manually by right clicking the response and click "add extraction rule". The text is split up into 3 different rows with lots of unreadable numbers next to it like this:
"0x00000000 7B 22 45 78 61 6D 41 6E 73 77 65 72 49 64 22 3A {"ExamAnswerId":
0x00000010 22 37 35 37 61 33 37 33 35 2D 65 36 32 36 2D 34 "757a3735-e626-4
This will sound dumb, but I somehow need to extract 3 different parameters, only because I can't copy/paste it -- and this is also where I think I fail.
the ExamAnswerId is important for me to fullfill another webrequest later on, but I can't seem to pass it on properly.
all input greatly appreciated !
Did you see this response that got posted? http://social.msdn.microsoft.com/Forums/en-US/vstest/thread/b26114a2-7a24-45eb-b5d1-01e9165045b0/
Just use the Extract Test like they suggest and you should work fine. Your Starts With could be "ExamAnswerId": " and your Ends With could be ". HTH.
I had a similar problem with the Extraction rule. Had to escape the quotes to get the condition to work. Like this:
Starts With: \"ExamAnswerId\":\"
Ends With: \"
Do following steps :
Add all available ExamAnswerId in a CSV file .
Now add CSV as Data source.
Lets suppose CSV file name is testdata and tableName=testData#csv and columnName=ExamAnswerId.
Please note when you will add data source you will see table name.
Replace this:
["ExamAnswerId": "757a3735-e626-412b-934c-e577c6963d51"]
by this:
["ExamAnswerId": "{{testdata.testdata#csv.ExamAnswerId}}"]
I managed session in JSON. The following link worked for me:
https://social.msdn.microsoft.com/Forums/vstudio/en-US/b26114a2-7a24-45eb-b5d1-01e9165045b0/cant-fetch-json-value-and-extract-to-parameter?forum=vstest
Example:
0x00000000 7B 22 53 65 73 73 69 6F 6E 22 3A 22 63 66 39 37 {"Session":"cf97
0x00000010 64 33 65 61 2D 36 39 38 33 2D 34 31 37 30 2D 38
I created "Extrat_Text" with variable MySessionID
Left Boundary "Session":
Right Boundary ",
Then I passed {{MySessionID}} in subsequent request in place of Session.
Or we can use regex (Positive look ahead and Positive look behind)
For example I want to get access_token property in a JSON result looks like this
{"token_type":"Bearer","expires_in":"3600","ext_expires_in":"0","expires_on":"1474420129","not_before":"1474416229","resource":"5fe3f443","access_token":"eyJ0eXAiOiJKV1QiLCJhbGci"}
I can use this regex:
(?<=\"access_token\"\:\").*(?=\")
