Thanks for your input, Floyd. MySQL turns out to be very strange, the longer you work with it the stranger it looks. We can be rather sure that your issue had some other chain of cause, but an interesting finding.

Thanks for your hints. A local web server is exactly beyond the "small and simple" scope of this question - do not add any unnecessary load to the old notebook. In a future scenario with upgraded hardware, things may look different - I try to avoid all the hassle with getting all the things correctly running on a different machine...
As for the MIME type, I found it on the stackoverflow answer; anyway, my blocklist is too large to fit the size parameters, so it won't make a difference.

The last machine crash was on Sep 11, 5:06 in the morning. No crashs since then, and no database problems either. What a coincidence! A postmortem would be nice, but my impression is that our admin prefers to repeat that at a customer site (the problems happened on our test system in the office): obviously, it works NOW.
Bernhard Hiller 14-Sep-18 4:02am View
In both cases, there was a crash of the machine, as can be seen in Windows eventlog with id 6008: "The previous system shutdown was unexpected". There were 70 (!) such crashes within 4 days, and they ended on Sep 11. I do not know what was changed on that machine, our admin will have to find out.

In the title, you talk about "WPF", but then your code uses "Windows Forms" - they are different. With WPF, use MVVM pattern, do not access properties of UI elements directly, despite Microsoft still keeps that doable.

Where is your problem? You just need to iterate thru the input data in junks of 3 bases, find the amino acid for the triplet, take the next triplet, etc.

WPF is not about replacing Windows Forms Controls by WPF controls. Learn some really basic concepts of WPF. Start with "Binding" in order to get into MVVM.

Your code will fail when 2 (or more users) save data to the database at the same time. The generation of that number must be delegated to the database.

Did you miss some {} when you copied your code here? In order to get that compiler warning, the code should rather look like
if (sub != "")

Reminds me of a bug introduced by genius programmers in the US headquarters of a previous employer: they reasoned that an IP address can be represented by two floating point numbers which get joined by a dot.

"offline" - that's why you tagged the question "ASP.NET", isn't it?
No, the way you try to translate won't work for sentences, that won't even be useful for words, as words may have several meanings which means that a choice of words must be presented in the other language. Haven't you ever used a printed dictionary?

"debugging managed code & native code at the same time" - I suppose the problem could be with the UNmanaged code of your app. Add some logging to find out where (code line) your app crashes.

Compile time or run-time error? Which line?
by the way, catch (Exception) {throw new Exception() is nonsense: you throw away all the information you could get from the original exception. Don't do that!

Your code is such a terrible mess that it is hard to see what you do. No obfuscator required... Let's write it down in 3 lines, all the rest is either dead code (yes: dead. What do you do with string json = Response1.Data.ToString();? NOTHING!)

Are you sure you understand the data type of the response?

How does that service launch PDFGeneration.exe? Is the PDFGEneration.exe actually launched by an application running in the context of ABC (perhaps even hidden in the System Tray) which communicates with your service? Or did you actually mix up account names when you wrote this question?

Not all combinations of digits and characters are valid / acceptable names for tables or columns. Some inaccaptable names can still be used by escaping them (if the database engine allows that - e.g. Oracle does not). The rules differ between engines, but generally dots (.), commas, national characters, backslashes, and SQL keywords should be avoided.

An important note: this is not at all a problem of a "login form", it is a problem of text comparison in Microsoft databases: the clause

Other databses, e.g. Oracle or postgres, behave differently.
Do thing s correctly, i.e. store the hash of the password insetad of the password, and problems will be gone.

Oh dear... Did you place the database file to Data Source=c:\\eminosoft.db on the target computer? By the way, that is a very very bad place for a database file. SQLite database files are often stored in the user profile; c:\programdata\YourCompany\YourApplication\YourDatabaseFile.db can be an appropriate alternative.

Well, let's say the download has already occured. Otherwise, how could the image be shown in the browser at the moment it is dragged to the desktop?
Perhaps in case of an "expires" header, a new download may happen. Not sure how browsers do implement that here.

Do mean similar to an ICA (Citrix) session where you can add username, domain and password (either ceartext or encrypted) in a .ica file?
Well, it's not "secure from hackers", as any hacker could use that ica file to connect to the server....

Do you actually understand your code snippet above?
I doubt. Because it looks to me that the most important part of te code is in _licensePlateDetector.DetectLicensePlate, i.e. you did not show it.
By the way, can your software "learn" from training data?

Well, the question is actually: where to get a phonetic translation and comparison algorithm / library from for Kannada?
If I remember correctly, the "literal" transliteration is of that South Indian state is Karnataka, but a more phonetic transliteration is Kannada...
I do not know such a library / algorithm, perhaps you have to create it yourself. Or you could find one on an Indian programming forum (in that case: would be nice if you tell us about it here).

What's the datatype of the photo column in the database?
How many bytes did you get into byte[b]?
Is it really an image which was saved into that column or something else (e.g. a pdf)?

Is that a follow-up question to

Note the "Changed" part of the name - if the index was already 0, and you set it to 0 again, it is not changed, hence no event!

20 Million records are surely larger than 1 Gigbyte (that's merely 50 bytes per record - do you think such a low number is enough)? Who has such a fast internet connection (look at the tag: ASP.NET) to transfer that within a few seconds? Hardly a company has a Gigabit network internally.

What does that 'MemoryStream memoryStream ' do? I do not see it used in your code. Remove it!
Also, for such big files, I'd prefer larger chunks of data than 16348 bytes.

ASP.Net - that nmeans you will send the data over a network. Calculate. How many bytes per row? Perhaps already a 100 just for html tags, then add the content; or also css and javascript tags...
That is: you want to send about 1 Gigabyte of data over the network. Is that a great idea?
