I just started using WPF after spending ages using WinForms like a moron might do.
I want to animate a transition that occurs when you press a button.
I want the controls currently on the window to fade out (which I can do) and then have another set of controls fade in (which I can also do).
However I want to animate a transition between two window sizes, with a vertical and horizontal change. This I have a problem with. Everything I find on StackOverflow seems to be a massively overcomplicated mess to achieve what I assume to be a relatively simple goal (because you're just doing a DoubleAnimate properties) but that doesn't seem to work.

I'm learning C as a almost-complete-beginner to programming and computers. Just brushed up on memory systems and software to refresh my memory. Also messed around on CodeBlocks after learning stuff about statements, functions, conversion characters and arrays.
Chose C to begin with as it was what I was told as the best first language by several people.
My question is; any good complete beginner learning resources and any suggestions for a good active forum for learners?
Local business might want to upgrade their site / get a new one to add eCommerce features and also maybe phone apps. Someone on here has to do freelance web related things, how much would you charge?
I googled and got some outrageously high numbers for these.
>>51794056
>Learning Resources
>Active forum for learners
Have an idea for something, begin work on that thing in earnest, when you want to achieve something you don't think you can achieve on your own, Google it. If Google turns up no useful results (which it absolutely should 99 times out of 100, assuming you're know how to Google), then either post here or on stackoverflow.
>>51794067
How much is your time worth? Look at some local prices and adjust accordingly. Also get a contract of some kind written up before you start working, I'm sure there are some templates online that you can use.
/g/ be straight with me
I've been having some personal issues at home and couldn't study a lot for the past month
I'm doing a java final with a bunch of stuff on GUI but I know jack about GUIs
What are the odds I can get an 80% on it if its an open book, open note, open internet exam?

>>51794051
>Everything I find on StackOverflow seems to be a massively overcomplicated mess to achieve what I assume to be a relatively simple goal
Because WPF, like everything related to .NET, follows the paradigm of "have a gigantic pile of features and hope the programmer can figure out how to piece them all together into something usable".
Just use Tcl/Tk.
If I were using Lambda-styled LINQ expressions, how might I iterate over a list of other objects within an object?
I.E. ObjectA has property List<ObjectB>
ObjectB has property string Name
How would I iterate through them to find whether or not the list in ObjectA contained an ObjectB with a Name of Richard Stallman?

I like WPF. After my foray into web dev, it is very similar to some web frameworks. My biggest issue with WPF is it'll never come to Mono, because Microsoft will never play ball with FOSS communities.

You know MS works really closely with mono right? They fix bugs regarding their frameworks to make them work better on mono.
Also CoreCLR is MIT licensed. ASP.NET is full open source.
The only reason WPF won't ever work on linux is because it's deeply ingrained with platform specific stuff on windows, and it would be a giant cluster fuck to port.
Moonlight exists though, which was made with MS's blessing.

There's also always GTK#.
I made a (shitty) battery monitor

}
while true; do
bat=$(acpi | cut -d',' -f2 | grep -o '[0-9]\+')

if (( "$bat" <= "15" )); then
notify-send -u critical "Battery Low" "Your battery is at $bat%. Please connect it to the charger."

You might need two for loops to do this.

And I want WPF, I like it, I just don't want to lock everything I write in it on Windows. ASP is on mono, yes, but importing projects written on Windows into monodevelop always fails, its as if it's both open source and available on multiple platforms, but its not really cross platform.
>>51795573
Eh.
GTK is notorious on Windows, I bet the GTK devs are on some level deliberately uncaring about GTK bugs on Windows (because lolwindows), but that kind of shit is why Windows kids don't consider libreoffice a suitable replacement for Microsoft office. Libreoffice is perfect on Linux, the bugs on Windows are clearly not from the Libreoffice devs.

UI is highly subjective, I much prefer it over the bulky ribbon. The thing about UI design is that everyone has their opinion and everyone wants to pick on FOSS devs about aesthetics. It really just comes off either as pretentious or autistic.

yeah, they actually do, there is nothing magical about C, its just another high level language, it has to use the same kind of compiling optimizations any language would use. Any languages speed depends on the skill of the compiler writer, any high level language can be made to run 'as fast as C', C is not the fastest compiled language, thats a meme

Probably in the heavy maths area. Fortran is still unparalleled there..... but since it's good math functionality had gotten wrapped in easy to use c c++ c# python and ruby libraries.... you don't need to touch it yourself unless you're REALLY bored.
>>51797385
So, you know those languages you mentioned? Compiled vs interpreted is an implementation detail. Haskell can be compiled, or interpreted. C can be (not many interpreters out there exist, but since do). Lisp can be compiled or interpreted, often both in the same runtime. Even qbasic had a real compiler.
>>51797589
Is that it?
Why is that important if it eliminates the need for pointers?
In an excel table(.xls) where there are 3 rows and 5 columns, can I make an array where I can change values by pointing where I want them?
excelsheet[3][5];
testbook << excelsheet[0][3] << "0.432";
I tried to do that thinking that it will change the data to that, but it just creates a new excel sheet and it inserts it in the first row of the first column.
>>51797576
C++: better theoretical efficiency (assuming the programmer even knows how to achieve this - most don't), better traceability, better function pointers
C#: garbage collection, elegant syntax including lambda expressions, faster overall development for almost any application.
Basically it's a question of what's more valuable: your computer's time or your programmer's time.
>>51797611
C# hasn't found some clever way to get rid of pointers, it did so by sacrificing speed
>>51797606
>Compiled vs interpreted is an implementation detail.
thats right, so why would you use a language like Julia that can only run interpreted when you have languages like Go, D, Swift which can run both interpreted and compiled?
>>51797579
Undefined behaviour makes C inherently faster than most other languages.
Sure, other languages CAN be faster than C, but in practice, they're not. Most of the time when other languages benchmark faster than C, it's because some sort of computation was actually skipped or it's something that is very difficult to represent in C.
>>51797579
> yeah, they actually do, there is nothing magical about C
No they actually fucking don't. There is nothing magical about C, but there is a lot of shitty overhead in both of those.
Haskell has garbage collection and allocates lots of memory on the heap as well as using linked lists for everything which destroys its potential performance.
The 'compiler writer' idea is CS101 kiddy stuff since it's irrelevant anyway. Haskell has been heavily optimised over 15 years and they still used linked lists.
Fucking failure.
> C is not the fastest compiled language, thats a meme
C++ and ISPC are the fastest compiled languages realistically because of function inlining in areas that C can't, like function pointers.
What language do you think is faster? Whatever shit you are using to avoid learning C++?

Seems pretty fine considering I don't need 2.34 seconds faster code execution with what the average modern computer is like nowadays. Plus it's not like I'll even get my code to that point as a beginner without what feels like 10 years of exp in C++.

sry, but you are just spouting hearsay, there is nothing about the heap that slows down a compiled language, the fact that Haskell uses immutable abstractions like link lists doesnt slow it down either.

God damn I hate people with that fucking attitude. With slower execution time comes more power draw meaning shit like my cellphone gets worse battery life.
Also, why not run efficient programs on faster hardware? That way shit is even faster.
>>51797700
>its used widely by a lot of people so finding help is never an issue
C# doesn't seem any less used... In fact it's easier to use because everything is built into the framework.
>>51797688
It's really not difficult to write efficient code
You just can't take all the cushy shortcuts and sweep things under the rug to be garbage collected like modern languages encourage you to do, so there's a lot of unlearning involved for most people
>>51797717

I'm apathetic about Haskell and you are seriously retarded.
Try actually trying to speed something up sometime. Try profiling.
Heap allocation is fucking slow when it is done frequently, not to mention that it blocks when allocating from the global heap.
Linked lists are fucking slow. Pointer chasing is fucking slow.
You have no idea what you are talking about.
>>51797797
I mean C/C++ are great languages but for beginners it's pretty much "No fun allowed: the language" unless you have 10+ years of experience and know the complete inner workings of the libraries you're using and the language in its completeness.
Debugging shit for 2 weeks and wondering why some retarded thing won't work when you could be creating a cool new part of your program, or an entirely new project just plain isn't fun.
>>51797836
Sure. Except when someone else actually uses the software you write. Then it's not fun for them.
The comparison between language speeds seems dumb.
In my domain, most of the time spent is waiting for disk reads or slow network I/O. If you're waiting for disk, it doesn't matter which language is waiting for the disk.

A tiny amount of performance, that a newbie programmer wouldn't even be able to make use of most likely is irrelevant.
That also doesn't include the fact that they could easily fuck up their code in 100000 ways and cause memory leaks, buffer overflows and other shit.
So really you have more to lose using C/C++ than not using it, as a beginner anyway.
>>51797859

>Undefined behaviour makes C inherently faster than most other languages.
no it doesnt, the reason that C has so much undefined behavior is that makes C non-conformist to any kind of programming constructs which is what makes C always the default systems language and C the best language for writing compilers. safety rarely if ever costs anything except in rare occasions that bounds checking is done, and that can usually be turned off so that it will run as fast as any 'unsafe' language

Look up the Microsoft Office Open XML SDK.
Be warned, it is not for the faint of heart. The SDK lets you do pretty much anything you could do through Excel (want to create a conditional style that changes the color based on the current value returned from a web service? No problem!). The flip side of this is, creating even a simple document can require 45 metric shit tons of boilerplate code.
I actually wrote a 'generic DataTable to XLSX exporter routine' for someone a few weeks ago. Want to just dump all the data as strings/TEXT? No problem, 20 lines of code, done. Oh, you want to support DATE columns? Now you have to create the package, the workbook, the worksheet, the sheetdata, a numbering format, a cell format, a cell style...

actually, google says that it's because you have access to destructors which can be set to destroy any info, or which can be configured to act as a finally clause in the case of datastream rupture. Ultimately, I think you'd want to try that lock within the try block anyway so that you don't accidentally lock yourself out.
It's kind of like, why would you leave your car on, put up your windows and lock your doors when running back inside only because you hope you that upon closing your car doors would unlock themselves.
Stop being stupid for the sake of stupid and just put in the necessary effort instead of constantly trying to help technology "improve" by lowering the standard of conduct.

As someone who has been through arguments with clients about this on several occasions...
Input simulators using recorded sessions = fragile as fuck
Input simulators using image interpretation = fragile as fuck
For any system a client needs to do something like this for, we either a) write a code injection attack to insert a DLL with a remote control setup into the program, and just have it call the internal functions that are needed, or b) just write a new program that provides the functionality of the existing one in a controllable manner. B is the first choice, and faster than making the other options work for probably 90% of the stuff I've seen.
I'm trying to understand why this function refuses to work if len is initialized to 0 or 1.unsigned get_linelength(FILE *fp, const char delimiter)
{
long pos = ftell(fp);
unsigned len = 0;
while (fgetc(fp) != delimiter)
{
len++;
}
fseek(fp, pos, SEEK_SET);
return len;
}
If len is initialized to 0 or 1, the while loop only goes through the loop once and exits, len always returns 1.
If it's greater than 1, the loop will work as intended, incrementing len until it encounters a specific delimiter character.

So union seems like what I want but[5,2] `union` [2,2,2] /= [2,2,2] `union` [5,2]

So I have no experience coding sdl and glfw, yet Im going to make a choice, I started with glfw but then I felt to to lazy to have to deal with shaders since I'm only doing 2d stuff, so I switched to sdl2, I started looking up some sdl examples for just displaying a simple png image on the screen, all the examples I found were outdated.

I'm calculating the prime factors of several numbers and storing them in a list. I'd like to then use those lists to calculate a lowest common multiple. My issue is on how to take the lists for the individual numbers and combine them in to a single list that contains prime factors for the LCM.
So if I were to have 3 lists:
[7, 5, 5, 2]
[2, 2, 2]
[5, 3, 2]
and "combine" them the expected result would be: [7, 5, 5, 3, 2, 2, 2] (not necessarily sorted).
>>51799305
The initial value of len can't have any effect upon the behaviour of that function. The return value is the initial value of len plus the number of times it gets incremented.
That is all.
>>51798177
Assuming you're talking about C, yes. C doesn't really have a true boolean type. A zero evaluates to false in a boolean expression and a non-zero evaluates to true, regardless of the type.
>>51799392
C99 does.
Suppose I created my own programming language. What are the patterns that would make it perform well? If I wrote it in C, what optimizations and data structures would make it a viable general purpose language?
I'm curious because stuff like Python and Lua were probably slow as hell at first, but that didn't really hinder their widespread adoption. Now they're pretty fast.
If the 80/20 rule applies, what 20% of code will give a language 80% of the speed boost it needs to not be a toy anymore?

>>51799415
If you want your language to perform well without having to put in a huge amount of effort, I'd say your best bet is to compile to LLVM IR.
>>51799387
look dude all I know is that if len is set to less than 2, len doesn't get incremented more than once.
and i don't know why this is happening
it works perfectly fine otherwise
>>51799454
From what you've shown, that's not possible. There must be something else that's causing it.
>>51799454
There is absolutely no way the value of len should influence the behavior of that function. There is something else (possibly outside of this) messing it up.
>>51799376
for every unique element a of the union of all input lists, you want the final list to contain n 'a's where n is the maximum number of times a appears in each of the input lists?

>>can't even convert binary to ascii using parallel
hey this might be obvious to you, but I'm pretty noobish: how is this a completely serial problem? Can't you read the file in pieces and process each piece individually and then have some kind of collector put the pieces all together? If you load the file and memory-map it so you can treat it like random access first. IDK much about c# though.
>>51799430
Sure, but Python's considered "fast enough" by many, even for things like number crunching; the libs link to native fortran code and it seems to help.
How did Python get there, performance-wise? Or are you saying a language doesn't need to be fast in order to be generally useful and accepted by hackers?
>>51799449
I'm just having trouble identifying what that huge effort actually consists of. I'm reading source code of many virtual machines and I don't know what choices were the most significant performance-wise.
They introduced caching at various points like vtable lookup, made pointers and fixed-precision numbers a sum type, enabled compilation of code down to machine instructions at runtime so as to avoid interpretation... The list goes on.
>>51799415
Python is not fast in any regard.
Lua is only fast for an interpreted language.

Nobody is going to be able to tell you that without deep knowledge of the system in question. Maybe you can find a talk on youtube from someone who worked on CPython or LuaJIT.
>>51799561
http://stackoverflow.com/q/4911762
>>51799519
A language doesn't need to be fast if the language itself is primarily a means to delegate to native code.
E.g. Python itself is about the slowest language in widespread use. If you were to take typical Fortran number-crunching code and translate it directly to Python, the result would typically be 100x slower or worse.
So you don't do that. You use NumPy to do the actual calculations so that the interpreter overhead is per array, not per array element.
