I've been trying to simulate a keyboard keydown/keyup event in C#/WPF
I've got a global listener, but I want to now simply emulate a different key being pressed.
How in the fuck do I achieve this?
I've tried using InputSimulator but it doesn't work at all, the entire thing appears to be completely hollow (none of the classes have any members, even though they appear in references just fine).
I can't think of any reasonable way to achieve this behaviour.
>>52346679
Bump
>tfw askin myself y u fucks wont reply
>>52346894
The aim of my program is to delay the "keyup" event somehow.
I went with registering a global keyhook, reading that input and then emulating a keydown event, then when the keyup event is called wait for a specified period of time then have the keyup event play.
But I have literally no idea how to get this to happen.

The following indicates that you are potentially passing multiple values in, and then puts them in a listdef alcm(*args)

Do cosh and tanh work? If so, sinh(x) = cosh(x)/tanh(x).
>>52347284
I've already got a global key listener.
What I need to do is emulate a key being pressed.
So when I press C it'll emulate the "down" event of the E key, and then when I release C it'll emulate the "up" event of the E key.
I'm not sure why it's so hard to emulate a keyboard input.
>>52347284
This reminds me of the time I wrote a snes controller -> keyboard application and the emulator wouldn't recognise the keypresses because the c# method for it (sendkeys is it?) was shit, had to find out what the on screen keyboard used and replicate that instead.
To be fair to it, should have just used an ftdi and made it a game controller but it was for learning.
Still shit though.

don't know the solution but I hope you've properly abstracted your class as a AsyncKeyInputObserver or equivalent using the observer pattern and subclassing for the KeyboardAsyncInputObserver

None of this code makes any sense any more, because I've gone through so many different iterations and solutions that none of it even lines up in my head.

There is an example solution floating around somewhere dedicated to sendkeys, i know because i initially used it thinking i'd fucked up somehow for the aforementioned emulator reason, it does press the keys but it doesn't do it in the same manner as an actual keyboard, making it shit. Go with the dll method, it just werks.

You'll learn to love it. It's a bit like stockholm syndrome.

It's hardly stockholm syndrome, I'm chasing it but it just keeps evading my grasp.
It's just a fuckload of syntax I don't understand using Ascii codes I don't remember.
Like in this specific case, how do I emulate the "E" key?
What is the code for designating keydown and keyup?
How would I make this customisable?
It's an absolute fucking mess.
>>52347600
It's not really that bloated
Only 2 redundant parameters out of 4
>>52347676
>using Ascii codes I don't remember.
Not him, but you do know about the ord and chr functions right?
>>52347676
I believe you can use System.Windows.Forms.Keys as the first parameter
KEYDOWN is 0
KEYUP is 2
>>52347684
Nope, never needed them, I've been blissfully enjoying my relatively simple C# syntax, if I ever needed Win32 stuff I'd go directly to a source and copy the whole thing into a class and forget about it.
Now I'm forced to interact with this horrible shit.

if i am a beginner and i learn my first language
How long would it take to learn a framework?
>>52348146
If you know the language you can use any framework straightaway, you just need to learn the function names which you can easily find out in the framework's documentation.
>>52348146
they're completely different beasts
learning a first language in its simplest level is just understanding how different concepts operate with each other, whether these concepts are variables, functions, classes, etc. At a more advanced level, it's using tricks accumulated through seeing other's code, your own optimizations, as well as learning how to use specific libraries to achieve what you want
learning frameworks is somewhat equivalent to learning a language at its more advanced level. It's almost the same as learning libraries in and out, but you need efficient use of the tricks previously mentioned since your code will be all over the place, and lack of clear structure will frustrate you quickly
MySQL is nice.
>>52348229
Not always. Some frameworks have their own DSLs or pretty much rewrite the whole parent language, which might as well be called a DSL.

The tensorflow they opensourced is actually just a small part of it. Internally, they use several still closed-source tools such as a custom cuda compiler. As a result, the opensource tensorflow is significantly slower than previous options (theano, caffe, torch) and not viable for actual use yet. It also doesn't have multl-gpu support yet which the other options do.

I ended up running out of time on this problem, but I still really want to know what the solution was supposed to be, if anybody can help that would be great.
If anything isn't explained well enough, or if any of my code is hard to follow, just ask.
Pastebin of the original problem: http://pastebin.com/HhG4617W
(TL;DR: You're lost in a subway system, and there are no maps to show you where you are. All you have is a list of tracks and where they take you. Is it possible for you to take a set series of tracks from any station and always end up at the same place?)
examples of trees: http://pastebin.com/VfAQYdEF
my solution: http://pastebin.com/3sbp8k29
The basic idea is to put a rabbit at each station initially, and have them all take the same track, and work my way down the tree using a breadth first search. The problem I run into is I don't have enough memory to store the queue once my program gets to the about the 25th level of the tree
The only way I can think of to get around this is to either prune the tree more, or to find some other method which generates smaller trees.

The requirements for ML are:
-very quick development cycle
(because most of the time you're changing a few hyperparameters and trying the same model again)
-speed
(otherwise you're waiting a month to process data before you can choose new hyperparameters)
-ease of modification
(otherwise you spend a day adapting a model slightly despite their similarities rather than a few minutes).
Python is great at 1 and 2 and it has C syntax so everyone's familiar with it. For 2, the fact it's dynamic/typeless means you can get something (very buggy) running very quickly. In practice, it's actually an inconvenience but that's not how it was initially interpreted. Now everyone's kinda stuck with it, and so nobody even looks once at a library that doesn't have extensive unit testing and over 90% coverage.
Python sucks balls at 2 but it doesn't matter because CPUs are too shit at matrix operations (which is what ANNs are bottlenecked by), so everyone offloads the work to the GPU. Thus, the python code is actually a very high-level set of bindings to C and CUDA code, and the speed of the host language only matters slightly because it takes much longer to fetch the data from the disk and to perform operations on the data than it takes to prepare the data to be sent to the GPU.

Yeah, I know. I just hate using loops.var type = ["jpg", "png", "gif", "webm"];
type.forEach(function(elem, index, array) {
if(thread.files[elem]) {
document.querySelector("#filecount").insertAdjacentHTML("beforebegin", "[<label for='" + elem + "'>" + elem + "</label>]<input type='checkbox' id='" + elem + "'/>")

});
my minimax isn't terminating for some stupid reason
on the plus side it looks like it'll be able to search more than 2 million nodes within a second which is a lot better than I was expecting after how badly everyone has been shitting on pythons performance

It means you'd be getting 100m nodes a second with the same algorithm in e.g. java or C#.
>>52350208
fucking sucks, I'm mostly hoping someone who has already solved it can explain their solution to me.
Obviously generating the tree is the wrong way to go (unless there's some god-like pruning strategy that I'm unaware of), but I couldn't find another idea.
There's probably some way to recognize if there is or isn't a solution more or less immediately out there.

What the fuck did he just say?
>>52350385
I'm already using a deque and I can't really see how MAB would be usefully applied to this problem, considering there's no real way to calculate loss or regret in this problem.
in either case neither of these would have affected memory usage, which was what really killed me.

>>52350414

A dequeue is not a double-ended search. The regret is -1 when you reach the start position, 0 otherwise.

Any french here? or anyone who solved problems on http://www.france-ioi.org/ ? or anyone who can read french and want help me solve this problem?
Problem: http://www.france-ioi.org/algo/task.php?idChapter=656&idTask=0&sTab=task&iOrder=4
I need to solve the 5 problems to pass to the next level. i solved 4, the 5th gives the correct output on 18/20 of tests, i still fail two.
if anyone wants to help i can translate the problem
else, how can i cheat of the test? It already told me the correct output on test #6 is 4
thanks for any help given

>>52350627
I thought you meant a double ended queue - https://en.wikipedia.org/wiki/Double-ended_priority_queue
Which is the only thing I've learned that could be called "double ended" and is also the only thing that shows up when I google "double ended search"
Assuming a double ended search is exactly what it sounds like, though, I would need to know the end condition before I started searching, which is (as far as I'm aware) impossible. You're not made aware that the station that the meeting path will terminate at is any specific station before you start searching, it's only after the search is over that you could know where the meeting path terminates.
Basically "how can I preform a double ended search when I only know of one end?"
>The regret is -1 when you reach the start position, 0 otherwise.
So the regret is 0 unless I've found the solution?
I'm not sure how this would help matters

/g/ has like one janitor and the one janitor isn't very strict
it would be nice if they enforced the bump limit/posting duplicate threads rule like they used to. right now they do an interpretation where the thread posted before the bump limit is considered to be a legitimate continuation (as opposed to a duplicate) while any thread posted after the premature thread is considered a duplicate to be removed.
>>52350866
>MOOOOOOOM
>>52350866
That's how things work site-wide, it's just that /dpt/ is the only general autistic enough to constantly create early threads
Like, /brit/ has an unwritten rule that a new one can't be created until page 7, but if one is created before that and the janitor doesn't get it before the old one is past that point, they let it be

>>52350866
>>52350920
Point is, there's no reason to delete an early thread once the old one has started autosaging
After that point, any other thread, even created after the bump limit, just looks like a duplicate thread, and posters always flock to the first one anyways

>Point is, there's no reason to delete an early thread once the old one has started autosaging
yes there is, it discourages shitposters from posting early threads in the future. it's how they used to do it before we got these fucking trap threads

>>52351013
this is not some sort of game you delusional mutilated freak
and even if it were you're breaking the rules by posting threads early
instead of posting after the bump limit with some threads being traps and some being non-traps, you get most threads prematurely with some still being traps and some still being non-traps

>>52351029
>posting an early thread is now shitposting
get the fuck over it it doesn't make a fucking difference when people post a new thread 30 or 40 posts early
when people do it at 150, it gets deleted by a janny like it fucking should be
