AIR app hang freezes - actionscript-3

Help !
(sorry for my bad english).
I have air app, that loads data from sqlite db -> compare -> save to new table.
Debug and release test - (Flash Develop/Flex 4.6 Premium) works file.
Problem - app installed on 32/64 bit win 7, Hangs with "Not responding".
data size - have 1.5-4k rows, 4 columns no more than 200k.
i make a "trace" (on a few db files) over external txt file - result:1971- 1972 rows and ...something crushes.
func.: load -> compare w another data -> add to new array -> load if there is more data.
i found some solution, but it is not the perfect way - additional timer 1ms.
..new array -> check if more data is available -> timer -> load, but it is too slow.
Any ideas ?
Thank you - Best Regards !

How to make heartbeats for Autocad from a plugin (C#)

Im developping a plugin for AutoCAD on Forge. Via a custom command (Provided by the plugin), it will publish a big png (25000x20000 for example) and sometimes it causes a timeout and the workitem failed.
<report.txt>
...
[03/02/2022 22:10:41] Save changes to page setup [Yes/No]? <N> N
[03/02/2022 22:10:41] Proceed with plot [Yes/No] <Y>: Y

[03/02/2022 22:11:42] Error: An unexpected error happened during phase CoreEngineExecution of job.
...
Im guessing the timeout will be done by design (Work Item Heartbeat) but havent succeed to find the way to make the long plotting survive.
Is there anyone who can help me?
The suggested solution, HeartBeat.cs has been tried but it seems not working for my case (because the engine Im using is AutoCAD?) though the document said that it will be ok if my plugin will print something (to stdout(=report.txt?) or trace(the suggested one) before one minute silence.
Additionally the actual PLOT command is issued on a scr file which is loaded and is executed inside my plugin.
PS1.
The only way to print something on report.txt I find is
Document doc = Application.DocumentManager.MdiActiveDocument;
doc.Editor.WriteMessage("somthing");
and seems the doc doesnt work with threading.
PS2.
The limitProcessingTimeSec for the workitem has been changed to 300, but it seems not related.

How to modify checksum after making changes in Nokia 215 4G firmware?

If I change any character in the firmware file and try to flash it, it will failed. But it will successfully flashed if I changed the string with the same number of character if it's not a function.
After further searching, I found out about the checksum and that in order to flash the custom firmware, you need to calculate it and modify it in the firmware.
This is the firmware:
https://www.mediafire.com/file/ok2c0qodao5fld1/Nokia_215_4G_readed_test.pac/file
I use HxD to read the file.
If I search for checksum, I got some results ->
Also, I searched for sha ->
So here, I tried to change == with != and also I changed it to 1 == 1 but, It always failed to flash
I am lost. I don't know what to search for or from where to start.
I hope that someone could help me out!
Note: I can provide access to my PC to try the flash tool (nokia tool v0.060 using easybox) and maybe debugging in the phone.

chrome "aw, snap" crash, but can't see crash log in chrome://crashes but see DMP generated, so what is the quickest way to interpret this DMP file

I can see my page get crash(see aw, snap page) with 20% proprobility after 10 mins(otherwise it runs well like forever)
so I tried:
1) CPU and memory check with task manager, and see no increasing(so no leakage).
2) enable crush log in the chrome://settings/
result:
2.1) see still nothing in the chrome://crashes page, not even a crush ID (0 crashes).
2.2) see nothing in the folder under path
C:/%User%/AppData/Local/Google/CrashReports (nothing in) nor
C:/%User%/AppData/Local/Google/Chrome/User Data/Crash Reports (folder not exist)
2.3) but indeed see DMP in the:
C:/%User%/AppData/Local/Google/Chrome/User Data/CrashPads/reports
but seems they are not readable, and it also seems not the correct address for crash logs
3) can get chrome log either by command line arguments, or using sawbuck, but found nothing but only 2 errors, one for sawbuck itself, and another saying can't send the report to google.
So the questions are:
1) are those DMP the crash logs(the default Dir for dump file has been changed for chrome v50)
2) how can I abstract information out of the DMP file, if chrome://crashes page shows nothing (for chrome on windows)
p.s. 2 usage pages are found at https://www.chromium.org/developers/decoding-crash-dumps
https://www.chromium.org/developers/crash-reports
but seems it's not for windows without a recompile of chrome's component, is there any 3rd party tools to interpret the DMP file?
env informations:
chrome version: 50.0.2661.02 m
; Host OS: windows 10
The crash dumps (.dmp files) in C:\Users\<user>\AppData\Local\Google\Chrome\User Data\Crashpad\reports can be read by standard Windows debuggers. WinDbg is one tool (provided by Microsoft) for analysing these dumps; it's not going to win any beauty contents, but it's powerful and gets the job done. The recommended way to obtain it is, somewhat bizarrely, the Windows Driver Kit.
You'll need debugging symbols to make sense of the results, and these aren't included in standard builds of Chrome. To get symbols for both Chrome and the Windows runtime, set the following as your Symbols path:
SRV*c:\symbols*https://msdl.microsoft.com/download/symbols;SRV*c:\symbols*https://chromium-browser-symsrv.commondatastorage.googleapis.com
There are numerous resources on using WinDbg on the web; this cheat sheet contains some useful commands to get you started.

Is there a way to compare two .exes to see what differs between them?

Is there a tool / process by which I can decompile two .exes (one of which runs on a handheld device, the other which doesn't) so that I can get a glimpse into what differs/what the problem may be?
Of course, seeing that one has "00xA" where the other has "00xB" won't help me. I mean a way to see code that differs, or more likely, a compiled resource or config file difference, or some build option or so?
I'm almost positive the problem has nothing to do with code per se (if/while/switch statements, etc.) but with the project setup.
I cannot compare the working source, as it does not exist - I only have the .exe from which it came. The source I have available is a "reasonable facsimile" of it, but not exactly the same, at least not in project settings and configurations, etc.
UPDATE
Re: this page, I'm not familiar with some of the terminology; specifically, where it talks about a "FLATRELEASEDIR" - WTH?
Will this work to test my CE-bound* .exe on my PC:
Run depends.exe*
Open my CE-bound** .exe
Stare in wonder at the amazing plethora of errata and data
?
*Supposedly not to be confused with "adult diapers"
** "bound" as in, "that's where it's headed"
UPDATE 2
Here's what I see when running Dependency Walker on my app:
...but note my dilemma here.
UPDATE 3
Here's what I did to try to replicate my handheld environment on my PC as best as possible:
I wanted to just copy over the whole dad-burned thing (the entire handheld device representation from Windows Explorer), but it won't let me do that - it's not copyable, so I copied over just the "Program Files" folder (which contains the subfolder of my app and a couple of other folders which I don't know are standard or custom/peculiar to us).
This is from the handheld device where the .exe in question does run properly, so obviously (theoretically?) there should be no missing modules - Dependency Walker should run it and say all is well.
However, it doesn't; I get the same results as the one p[a,o]sted above.
Note: This is true even after selecting "Options > Configure Module Search Order... > The Application Directory > Move Up in Dependency Walker.
So since even an .exe that runs fine tests out as being "not ready for CE-time", how can I use this to accurately test which, if any, necessary files are missing?
Do I need to copy over other folders, too, or what?
UPDATE 4
So, the (supposedly?) missing modules are:
API-MS-WIN-APPMODEL-RUNTIME-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ERROR-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ROBUFFER-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-STRING-L1-1-0.DLL
API-MS-WIN-SHCORE-SCALING-L1-1-1.DLL
DCOMP.DLL
GPSVC.DLL
IESHIMS.DLL
If true, then why does the .exe run on the handheld?
Note: Other folders on the handheld are:
Application Data => only contains "desktop.ini"
BTExplorer
My Documents => contains a "desktop.ini" and several SQLCE databases (*.SDF)
profiles => contains an empty "default" folder
Recycled => contains a single ".lnk" file
Temp => contains a handful of ".tmp" files
Windows => contains a slew of folders and files, including several .DLLs, but none of those listed above
The "Program Files" folder has a ".NET Compact Framework" subfolder, but it is empty.
In the \Windows\AppMgr folder, there are some interesting files, such as:
Microsoft .NET Compact Framework.DAT
Microsoft .NET Compact Framework.DLL
...several other DAT/DLL pairs, including:
Symbol Managed Class Libraries.DAT (no corresponding DLL)
...and even a pair:
SSCS HHS.[DAT,DLL]
-- which is our company acronym (SSCS) and name of the project (HHS)
What generates these? From where are they referenced??
Another possible piece of the puzzle is that the handheld device on which the .exe does not work does not have a \Windows\AppMgr folder, and thus does not have those .DAT/.DLL files listed above...
UPDATE 5
Another oddity:
After reading this: "Files that install in the GAC go in the\Windows directory" in the book "Microsoft .NET Compact Framework" by Andy Wiggly, et al, I tried copying the Windows folder from the handheld device to the spot on my PC below the folder named "3910ProgramFilesFolderCopy" which looks like this in Explorer:
C:
3910ProgramFilesFolderCopy
Program Files
Windows <= tried to copy the "Windows" folder from the handeld on top of "3910ProgramFilesFolderCopy" so it would end up here
...but it only copies a few files before borborygmas occurs (electronic borborygmas, that is) and it tells me, "the system cannot find the file specified"
Heavens to Murgratroid!?! Why does it find some but not all? Looking at the Windows folder on the handheld in Windows Explorer, I see that many of the precious DLLs are greyed out:
Arggh, double-arg, and (&c)
For PC you could try .NET Reflector.
http://www.red-gate.com/products/dotnet-development/reflector/
You may try to use dependency walker to undestand wich DLL/APIs they need and check if those are supported on your device.

Where does GM_setValue store data?

Where does GM_setValue store the data to in chrome. I've tried to determine where the data is going but couldn't figure it out. I monitored with process monitor and saw that when I stored a value chrome was updating a chrome_iwoeoiifoi2h3iofhufsdfnvdf type of file and I opened that up with an sqlite browser but the data was not there. I've looked at all the recently modified files trying to find the data but could not find it.
Latest chrome/TM.
In Tampermonkey, GM_setValue() data is stored in a LevelDB database that can be found in the User Data Directory tree.
Once in Chrome's "User Data Directory" (EG: C:\Users\USER_JOE\AppData\Local\Google\Chrome\User Data\Default\),
navigate to the Local Extension Settings\dhdgffkkebhmkfjojejmpbldmpobfkfo folder.
(gcalenpjmijncebpfijmoaglllgpjagf for the Tampermonkey Beta.)
There you will find a LevelDB database, usually named CURRENT. You can manipulate it with tools like LevelDB JSON, but external support for LevelDB currently appears to be spotty and I did not find any working tools for Windows yet (might have to compile your own).
You can also use the Chrome Storage Area Explorer extension to explore the data.
As of Tampermonkey 4.3.6, you can see an individual script's data with the Storage tab in the built-in script editor: (if the 'Storage' tab is not visible, edit Tampermonkey Settings > General Config mode > Advanced)
OLD, Pre November-ish 2015:
Before, about November 2015, data was stored in a Web SQL database in databases\chrome-extension_dhdgffkkebhmkfjojejmpbldmpobfkfo_0.
Once you have navigated to the correct folder, you will typically see two files. On my machine, they are currently just named 4 and 6. These are both SQLite files (the backend for Chrome's Web SQL implementation) and can be inspected with a SQLite viewer/utility.
The (normally) larger file, 6 on my machine, is a somewhat disturbing list of 94-thousand userscripts! I'm not sure what purpose it serves, but haven't investigated it much.
The smaller file (initially, at least), 4 on my machine, is where all the information about/for your userscripts is kept. This includes any data set by GM_setValue().
For example, if I install and run this userscript:
// ==UserScript==
// #name _GM_setValue demo
// #match https://stackoverflow.com/questions/*
// #grant GM_setValue
// ==/UserScript==
GM_setValue ('foo', 'bar');
And then I inspect the `config` table in file `4`, I will see four entries like this:
[![DB entries for sample script][8]][8]
The one you want is the `#st` row. Notice how it has the `GM_setValue` data encoded? :
