Compiling and Run C file in Java Application : I am trying to build a Java application that compiles and runs C++ files. It also stores the output of the exe file in a text file. Can anyone provide a complete walk through on how to do it ?
I have already tried the solution provided [here](http://stackoverflow.com/questions/14826814/compiling-and-running-c-program-in-java) and the program showed `compilation successful` message. But I couldn't find the .o file or .exe file in the directory.

i have given a timer, to start from zero and end at 10th second and after 10th second timer should become 0 : if (coinMag == true)
{
Timer += 1 * Time.deltaTime;
if (Timer >= 10)
{
coinMag = false;
Timer = 0;
}
}
what i want is when the CoinMag is true the timer should start...i have intialized timer as public float Timer=0.0f; ..and after timer starts exactly after 10 seconds timer should be reinitialized to 0.

Seperate MYSQL results into seperate HTML Tables : I have the following in which I am trying to make seperate HTML tables after each group:
` $query = "SELECT * FROM NonBillableTime WHERE TimeIn LIKE '$MondayP2%' ORDER BY CreatedUser ASC";
$members = mysql_query($query) or die($query."<br/><br/>".mysql_error());
while ($row = mysql_fetch_assoc($members)) {`
**Example
HTML Table 1 would return everything with CreatedUser number 5
Then the table would end and a new table would start and return everything with the CreatedUser number 6.**
I am facing two issues
1. I don't know ahead how many users I have since it changes.
2. It needs to execute from `while ($row = mysql_fetch_assoc($members)) {` since I am doing other calculations on the fly
*Yes I want to use MYSQL and am aware of adding injection prevention*

callback() missing 1 required positional argument: 'event' : <p>I am trying to create a Tkinter-GUI for selection of data points for analysis. This GUI will be part of a bigger Python routine that reduces the data.</p>
<p>The data points are numbered sequentially (#1, #2, #3, ...) and there is one checkbutton for each data point. When one button is clicked on, the corresponding data point number should be added to a list, like so [1, 3, 7]. The code I have written is as follows,</p>
<pre><code>"""
GRAPHICAL SELECTION OF DATA POINTS FOR ANALYSIS
"""
# create an empty list of data points
selection = []
# import libraries and modules
from tkinter import *
# create parent window
parent = Tk()
parent.title('SELECT DATA POINTS FOR ANALYSIS')
# create callback functions
def callback1(event):
selection.append(1)
def callback2(event):
selection.append(2)
def callback3(event):
selection.append(3)
def callback4(event):
selection.append(4)
def callback5(event):
selection.append(5)
# create list call
Label(parent,
text="Check data points to be analyzed:",
font=('arial', 12, 'bold')).grid(row=1,column=0,columnspan=11,sticky='w')
# create checkbuttons
button1 = Checkbutton(parent,text='#1',command=callback1) # create widget
button1.grid(row =2,column=0,columnspan=4,sticky='w') # position widget
button1.bind("<Button-1>",callback) # bind widget to left mouse click
button2 = Checkbutton(parent,text='#2',command=callback2)
button2.grid(row =3,column=0,columnspan=4,sticky='w')
button2.bind("<Button-1>",callback)
button3 = Checkbutton(parent,text='#3',command=callback3)
button3.grid(row =4,column=0,columnspan=4,sticky='w')
button3.bind("<Button-1>",callback)
button4 = Checkbutton(parent,text='#4',command=callback4)
button4.grid(row =5,column=0,columnspan=4,sticky='w')
button4.bind("<Button-1>",callback)
button5 = Checkbutton(parent,text='#5',command=callback5)
button5.grid(row =6,column=0,columnspan=4,sticky='w')
button5.bind("<Button-1>",callback)
parent.mainloop()
print("selection =",selection)
</code></pre>
<p>I have created the checkbuttons and bound them to the corresponding callback function. Apparently, the event (left button mouse click) is also correctly specified, i.e. "". </p>
<p>When I run this code, the GUI is properly created and shown. However, upon clicking on any button I get the following error message:</p>
<pre><code>Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Users\ridim\Anaconda3\lib\tkinter\__init__.py", line 1558, in __call__
return self.func(*args)
TypeError: callback1() missing 1 required positional argument: 'event'
</code></pre>
<p>I am relatively new to Tkinter and I could not figure out what I am doing wrong. The syntax callback is apparently correct and the word "event" appears in the function definitions.</p>
<p>I would be very grateful if someone could tell me what is wrong with my code. In addition, I would like to ask whether there is a more efficient way of setting up the callback functions. Maybe, a single callback function with "if" statements.</p>
<p>Many thanks,</p>

Find sudoku grid using OpenCV and Python : <p>I'm trying to detect the grid in sudoku puzzles using OpenCV but I'm having troubles with the last steps (I guess).</p>
<p>What I'm doing is:</p>
<ul>
<li>Downsaple the image</li>
<li>Blur it</li>
<li>Applying a highpass filter (bilateral)</li>
<li>Thresholding the image, using adaptive threshold</li>
<li>Some dilations and erosions</li>
</ul>
<p>All this gives me the following images:</p>
<p><a href="https://i.stack.imgur.com/BoCzp.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/BoCzp.jpg" alt="Original image downsampled and blurred."></a></p>
<p><a href="https://i.stack.imgur.com/DfJio.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/DfJio.jpg" alt="enter image description here"></a></p>
<p>From now on, I need to detect the grid, and I found a few methods of how to do that but none of them gave me the confidence of being robust enough. </p>
<p>The first one is to find lines using Hough transform but I find a lot of spurious lines. </p>
<p><a href="https://i.stack.imgur.com/EZuOj.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/EZuOj.jpg" alt="Hough transform."></a></p>
<p>The other is using connected components, which gives me the best results. I tried to implement RANSAC as a way to get the right centroids, but I'm not having good results and also takes a while to get the answer ("a while" is less than 2 seconds, but later I want to use it in real time video).</p>
<p><a href="https://i.stack.imgur.com/q17rj.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/q17rj.jpg" alt="enter image description here"></a></p>
<p><a href="https://i.stack.imgur.com/ToPpJ.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/ToPpJ.jpg" alt="enter image description here"></a></p>
<p>Any idea how this can be done? I mean, how can I discard the wrong centroids and start solving the sudoku? </p>

How to compare single string chars in C++? : <p>I wanted to compare two single string variable in my SC and if they were different, I wanted to add +1 to my int data "fights", let's say <em>X[1] = A, Y[1] = B, add +1 to <strong>fights</em></strong>.</p>

1 <= N <= 100000;

cin >> Y[i];
if (Y[i] != X[i]){
fights += 1;

cout << fights;

What is the difference between QQmlApplicationEngine and QQuickView? : <p>I'm using <code>QQmlApplicationEngine</code> as follows:</p>
<pre><code>QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
app.exec();
</code></pre>
<p>But now I want to enable multisampling for my app, and <code>QQmlApplicationEngine</code> doesn't seem to have a <code>setFormat</code> method for enabling multisampling.</p>
<p>I found a way to do it with a <code>QQmlApplicationEngine</code> <a href="https://v-play.net/developers/forums/t/antialiasing#post-9745" rel="noreferrer">in a forum</a>:</p>
<pre><code>QQuickWindow* window = (QQuickWindow*) engine.rootObjects().first();
QSurfaceFormat format;
format.setSamples(16);
window->setFormat(format)
</code></pre>
<p>But it relies on the first root object of the engine being a <code>QQuickWindow</code>, which is not documented in Qt docs. So I don't want to use that technique.</p>
<p>Another way would be to skip <code>QQmlApplicationEngine</code> and create a <code>QQuickView</code> instead. This does have a <code>setFormat</code> method letting me enable multisampling, but I'm wondering, am I losing anything by switching from <code>QQmlApplicationEngine</code> to <code>QQuickView</code>?</p>
<p>In other words, what are the differences between these two classes?</p>
<p>One difference I found is this (from <a href="http://doc.qt.io/qt-5/qqmlapplicationengine.html#details" rel="noreferrer">here</a>):</p>
<blockquote>
<p>Unlike QQuickView, QQmlApplicationEngine does not automatically create a root window. If you are using visual items from Qt Quick, you will need to place them inside of a Window.</p>
</blockquote>
<p>This particular difference doesn't matter to me.</p>
<p>Any other differences?</p>

How can a file contain null bytes? : <p>How is it possible that files can contain null bytes in operating systems written in a language with null-terminating strings (namely, C)?</p>
<p>For example, if I run this shell code:</p>
<pre><code>$ printf "Hello\00, World!" > test.txt
$ xxd test.txt
0000000: 4865 6c6c 6f00 2c20 576f 726c 6421 Hello., World!
</code></pre>
<p>I see a null byte in <code>test.txt</code> (at least in OS X). If C uses null-terminating strings, and OS X is written in C, then how come the file isn't terminated at the null byte, resulting in the file containing <code>Hello</code> instead of <code>Hello\00, World!</code>? Is there a fundamental difference between files and strings?</p>

ARDUINO - how to take photo and measure to pixels of specific color : I am a PhD student in Faculty of Agriculture in Turkey. We are measure the leaf area of some plants in our studies. I have used a method that accepted and give almost realistic result.
I cut off leaves from plants and put them on A4 size white paper as don't touching each other. Then, take pictures vertically from A4 paper with leaves. Later, I get the pictures to Photoshop programme. Select the leaves by color range tool and check the pixel numbers of leaves from histogram. So I have A4 paper real size and pixel number, and I have leaves pixel numbers. I can calculate to realistic leaf area by using these components.
So this manual method is so effective from old methods, but if you have to measure lot of sample, It is also take time a lot. I need to make my own device that arduino based and It has to take pictures and analyse leaf area by pixel counting method as I explain above.
Is it possible to do it with arduino? Any idea will be beneficial for me.
Best regards.

conversion from lptstr to wstring : I came up with the same issue,in which I got a LPTSTR portname param as input from a function.I have to convert this into wstring,so that I can fetch the Port paramaters.
below is the code snippet in which am trying to copy lptstr to wstring.
void C_PORT_MONITOR::SetPrinterComPortParam(LPTSTR PortName)
{
#ifdef _UNICODE
std::wstring l_ComPortName;
#else
std::string l_ComPortName;
#endif
DWORD dwSize,le = 0;
dwSize = sizeof(COMMCONFIG);
LPCOMMCONFIG lpCC = (LPCOMMCONFIG) new BYTE[dwSize];
l_ComPortName = PortName;//mPortName;
if(l_ComPortName.length() <= 0 )
return;
bool SetFlag = false;
//Get COMM port params called to get size of config. block
int length = l_ComPortName.length();
int iPos = l_ComPortName.find_first_of(':');
int iChc = length- iPos; //remove the charactrers after :
l_ComPortName = l_ComPortName.substr(0, (length- iChc)); //remove the characters from colon //COM1
//Get COMM port params with defined size
BOOL ret = GetDefaultCommConfig(l_ComPortName.c_str(), lpCC, &dwSize);
_RPT1(_CRT_WARN, "C_PORT_MONITOR::SetPrinterComPortParam length=%x,iPos=%x,iChc=%x,l_ComPortName=%s",length, iPos, iChc, l_ComPortName);
if(!ret)
{
le = GetLastError();
_RPT1(_CRT_WARN ,"C_PORT_MONITOR::SetPrinterComPortParam LastError=%x",le);
}
I need to assign this portname to l_comportname. and I need to create a substring from this l_comportname as COM1 and I have to use this substring in getdafaultcommconfig()

<pre class="lang-cs prettyprint-override"><code>public void Configure(IApplicationBuilder app)

How to connect an asp.net web app to SQL Server : <p>I'm having some difficulty finding how to do this. I have an asp.net web app that I'm creating.

I've found what I think are the correct connection strings, but I don't know where to put them so that I can use them for several pages?</p>
<p>I found this <a href="https://msdn.microsoft.com/en-us/library/jj653752(v=vs.110).aspx#sqlserver" rel="nofollow noreferrer">connection string</a> and this <a href="https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring(v=vs.110).aspx#Examples" rel="nofollow noreferrer">example</a> that I am pretty sure I can use.</p>
<p>What I need to know is where do I put this so that I can use it on 5 - 6 different pages? If someone can point me in the right direction that would be enough.</p>

Automatically fetch date from string in javascript and return same string with formatted Date : I'm having input string like -
Hi, I'll reach on 17 Dec 2019
Its basically -
[some words] + [date in any format] + [any other words optional]
Will be whatever user enters.
My requirement is to fetch the date form the given string and format it and store it with same string. So the result would be like -
[some words] + [date in my format] + [any other words optional]
Would this be possible in javascript (without nodejs) as Im running this on browser directly.
Tried new Date(fullString) and I get the date but loose the other parts of the string
var input = "Hi, I'll reach on 17/12/2019. Please wait."
var userDate = new Date(input);
Expected - "Hi, I'll reach on Dec 17, 2019. Please wait."

How to fix commit order in GitHub pull requests, broken by git rebase? : <p>When I write code I break it into small logical changes that are easy and quick to review.</p>
<p>To do so, I use <code>git rebase -i</code> (interactive) to squash, drop and change order of commits.</p>
<p>I've noticed this sometimes leads to a different order of commits on a GitHub pull request (though the order is retained on the remote branch). </p>
<p>For example,</p>
<ul>
<li>commit 1</li>
<li>commit 2</li>
<li>commit 3</li>
</ul>
<p>might show up in the PR as:</p>
<ul>
<li>commit 3</li>
<li>commit 1</li>
<li>commit 2</li>
</ul>
<p>I've searched the internet and only managed to find this GitHub help page: <a href="https://help.github.com/articles/why-are-my-commits-in-the-wrong-order/" rel="noreferrer">Why are my commits in the wrong order?</a> Their answer:</p>
<blockquote>
<p>If you rewrite your commit history via git rebase or a force push, you
may notice that your commit sequence is out of order when opening a
pull request.</p>
<p>GitHub emphasizes Pull Requests as a space for discussion. All aspects
of it--comments, references, and commits--are represented in a
chronological order. Rewriting your Git commit history <a href="https://help.github.com/articles/about-git-rebase" rel="noreferrer">while
performing rebases</a> alters the space-time continuum, which means
that commits may not be represented the way you expect them to in the
GitHub interface.</p>
<p>If you always want to see commits in order, we recommend not using
<code>git rebase</code>. However, rest assured that nothing is broken when you
see things outside of a chronological order!</p>
</blockquote>
<p>Is there a way to work around this?</p>

Lots of times I feel it is easier to start from scratch, but I have a bunch of containers that I am not sure what their states are, then when I run <code>docker rm</code> it won't let me because the docker container could still be in use. </p>

Why Rails 5 uses ApplicationRecord instead of ActiveRecord::Base? : <p>We know that Rails 5 added <code>ApplicationRecord</code> as an abstract class which was inherited by our models (ActiveRecord).</p>
<p>But basically, I think every technical requirement we do with ApplicationRecord, we can also do with <code>ActiveRecord::Base</code>. For instance:</p>
<pre><code>module MyFeatures
def do_something
puts "Doing something"
end
end
class ApplicationRecord < ActiveRecord::Base
include MyFeatures
self.abstract_class = true
end
</code></pre>
<p>So now every model will be attached the behaviors of <code>MyFeatures</code>. But we can also achieve this in Rails 4:</p>
<pre><code>ActiveRecord::Base.include(MyFeatures)
</code></pre>
<p>So what is the benefit of using <code>ApplicationRecord</code>, do you think it is necessary to add <code>ApplicationRecord</code>?</p>

Wocommerce search by attributes not works fine : i developed a search by attributes in woocommerce and everything be ok. But one attribute not work in the search. The only difference that i find is that is an alphabetical attributes and the others are numeric.
For example the url
http://neumaticos.7vidas.com.ar/?s=&post_type=product&product_cat=neumaticos&categories=neumaticos&pa_vehiculo=&pa_ancho=175&pa_talon=&pa_rodado=
returns the correctly results but when i search by vehiculo (pa_vehiculo) returns all the products.
Someone know what can be happen?
Thank you!

Google Cloud Platform - one test app - $90/month cost - why? : <p>I have a small test Angular static html app(10MB) deployed via Firebase Console and thought it is completely free. It's not a Node.js app.
When I take a look a the billing panel a month later I sow these nice lines:</p>
<p>Compute Engine N1 Predefined Instance Core running in Americas: 2159.983 Hours - $68.28.</p>
<p>Compute Engine N1 Predefined Instance Ram running in Americas: 8099.938 Gibibyte-hours - $34.32</p>
<p><a href="https://i.stack.imgur.com/sQuTk.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/sQuTk.jpg" alt="enter image description here"></a></p>
<p>GCP, I love you much!!!</p>
<p>Tell me guys, how this can be? I almost didn't use this app, just opened it 10 - 15 times during a month.</p>
<p>Sorry but I completely can't see the benefits of GCP. I can have Apache hosting in my country just for $3 - $5 per a MONTH but not per a day and no pain at all.</p>

heroku: set SSL certificates on Free Plan? : <p>I would like to set some SSL certificates for one app I have on heroku (a simple application based on nodeJS + Vue).</p>
<p>I know if I upgrade to the Hobby Plan (7$ for month) I can have it automatically.</p>
<p>But for now it would too much money for a test application, so I am wondering if I can achieve some similar goal also with a Free Plan.</p>
<p>so:
Is it possible to set SSL certificate for an app on Heroku JUST with the Free Plan?
Maybe in a complicated/tricky way via CLI?</p>
<p>From the Heroku pages and documentation it looks not possible.
But I have to ask :)</p>
