Thank you! :)

Thank you for the response!

I'm a bit confused, because it seems to me, that I'm doing the same thing you suggested regarding the location of the context. I thought, that using statement automatically disposes the object or do I miss something?

I tried to explicitly call Dispose() on context in every loop cycle - and recreating it with disabled lazylodaing, proxygeneration and change autodetection, but I still get large memory consumption.

I'll definitely try the idea of 'lazy-loaded' attachments, but - at least for now - I don't see the difference between generating a ton of Visitor objects with byte array or a many of AttachmentContent objects.

Edit: Some weird behavior, I discovered: If the for cycles over 50 items, then memory consumption stays around 900 MB, even after Button_Click has returned. But when I call the listing function (with a new ZooContext, but it still looks for me, that I'm doing the same in the cycle), the memory consumption drops to normal...

Thank you for your response. It's weird, that for you worked reading from MemoryStream, even without explicit definition of CacheOption property.
Meanwhile, I found out that all what I needed was moving 'img.CacheOption = BitmapCacheOption.OnLoad;' line after BeginInit() and the code worked.
For me it seems, that we're doing the same thing, reading from the beginning of some MemoryStream, but somehow it's different. Nevertheless, I have working code :). Also, thank you for your nice article.
I've added my solution to the question, but I also accept yours for reassuring. :)

Did you mark class Data also as DataContract and its members as DataMember like you did with DataService?

Thank you for this detailed solution! I'm always stunned how detailed your solutions are. You're awesome ;).

Well, I also think we can close this discussion. My application is now working with both mouse and touchpad and that's what I wanted :) .

Thanks again.

Finally, it's working :D . I'm so happy.
After a bit research it seems, that I'm not alone with this problem. Synaptics' virtual scrolling feature is not working in some applications, but in my case the horizontal scrolling is working in Visual Studio (thanks for the tip to dig deeper in touchpad properties, where I found, that I can actually turn horizontal scrolling on).
When I'm listening for messages sent to my WPF application window using Interop, weirdly I receive WM_MOUSEWHEEL messages, even if I'm using virtual scrolling. However, the MouseWheel event still doesn't fire. Fortunately the HIWORD part of wParam is set correctly (at least for my purposes), so I can step zooming in and out based on sheel spin direction.

Now I'm just wondering, that what's this caused by? Basically, the application gets the message, but somehow it's lost in .NET.

Thanks for help and for reassuring, that my code and the error is somewhere else.

Thanks for your reply!

Well, it varies on application. In Start menu, Firefox, Internet Explorer, Spotify works, but in Visual Studio 2013 doesn't. In Github client neither, but interestingly for a moment it scrolled down a bit...

Thank you for detailed (and now official) answer!

To be honest this is the first time I heard about term 'degrees of freedom', which makes me feel a bit dumb, but at least I read about it now :) . Thanks again!

Basically, this application should serve for traffic simulation purposes (trains, metros, bus lines based on timetables or other vehicles based on recorded GPS routes), where the output is just a video. So I think you persuaded me, that WPF animations should not be used.

I really appreciated your comment ;-). I'm often having hard time making decisions. Thank you very much.

You're welcome ;-)!

Could you please describe, how the servers are physically connected to the network? It seems to me, that the only solution is using a router between the subnets, that has two IP addresses (one in each subnet).

Now I think I know everything :) . Thanks for your time to clarify me your application. This was a little out of box for me, that's why I commented. Even I checked the Wikipedia article for pound sterling, whether 1/100 pound coins exist :) .
Thanks again ;).

I thought about the case, when something costs 12.00 pounds. Then the cashier must type 1200, if I'm correct, and that means two "unnecessary" characters. I think that you can easily forget to type these two additional zeros. If there are plenty items, the cashier might not realise the mistake by looking at the total price.
On the other hand, I see, that if you have price tags mostly ending to .90, than both approaches have the same press count e.g. 1.9 = 2 numbers 1 decimal point vs. 190 = three numbers.

The main reason I asked, that I obviously see cash machines, that have product numbers stored in their memory or simply use barcodes. I can remember the cash machines used at grocery stores, where the cashier typed the price, but to be honest I don't recall which method they used.

It's my bad, that my question was confusing, sometimes I struggle to formulate my questions. Thanks for your reply, you already have the solution and I ask details :) .

Little edit: I presumed, that you have to able type prices like 1.95, but it seems, that you don't. In which case I found it more weird, that you display two numbers after decimal point, but you can't change the least significant one. But I understand that this was the best option for you :) .

Hello, I have read your whole question with answers, but I still have one tiny question - I'm just curious no offense intended :) :
Why should the cashier type double zeros for each round price tag? It seems, that cashier might save a little time and it's less probably that they type 0.12 instead of 12.00. Or do they have all price tags ending in .99 :) ?

What platform are you working on? WPF, Win32, Windows Phone?
You might check class InkPresenter: https://msdn.microsoft.com/en-us/library/windows/apps/system.windows.controls.inkpresenter%28v=vs.105%29.aspx
or you can play with MouseDown, MouseMove and MouseUp events.
What do you want to achieve? Hand-writing or something like the line tool in drawing applications. Also it would be a better start, if you inserted your source code.

Hmm, I don't like the approach, that you read the entire file to memory, but honestly I'm not a C expert :).

What about looping over the input string char by char and dynamically create the list of numbers. In this case, you need the number on first line just to test, whether you have read all the numbers.
Is there any reason you use the built-in function to convert string to char?

Hello,
How do you send the stream? I have one PCI voice modem, that is theoretically able to make phone calls, but it has audio input/output jacks on it, so you had to plug a microphone and speakers directly to the modem. I didn't know, that USB modems are also audio output devices, so I'm really curious how you do it.

After your comment I revised my solution, and you are right I had to improve ( by changing the queries, maybe I'm addicted to criticising queries :) ).

BTW, I like your method, that you comment why you rated.

I think this is the guy who previously wrote, that he have to write some question/answer system. For one question several answers can be.

I can't edit any foreign articles, this is why I wrote a comment. Maybe the guy describe it better.

That escalated quickly :D. When I came here, there had been no comments, but after submitting mine I saw 4. I simply have to speed up :).
