</code></pre>
<p>The first problem is in the constructor when checking for the file existing:</p>
<pre><code>if (!File.Exists(AuthenticationFileName))
File.Create(AuthenticationFileName);
</code></pre>
<p>This make the file to be busy in use. When later in my code i'm trying to use the file again to write to it i'm getting exception that the file is in use by another process.</p>
<p>The second problem is in the 3 places i'm trying to write to the file.
The first place:</p>
<pre><code>w = new StreamWriter(AuthenticationFileName, true);
w.WriteLine("Api" + "=" + cTextBox1.Text);
w.Close();
</code></pre>
<p>Then under it in another place in the code i'm writing again to the file:</p>
<pre><code>w = new StreamWriter(AuthenticationFileName, true);
w.WriteLine("UserId" + "=" + cTextBox2.Text);
w.Close();
</code></pre>
<p>And last:</p>
<pre><code>w = new StreamWriter(AuthenticationFileName, true);
w.WriteLine("JsonFileDirectory" + "=" + cTextBox3.Text);
w.Close();
</code></pre>
<p>The problems are first the file is busy in use since the checking if exist i'm doing in the constructor.</p>
<p>The second problem is that i want to make that if in the file there is no line that start with "Api" then write the Api part:</p>
<pre><code>w.WriteLine("Api" + "=" + cTextBox1.Text);
</code></pre>
<p>But if it does exist and the text is changed in the textBox cTextBox1.Text i want to write to the file the changed text to the place where the Api line is. And to append a new Api line.</p>
<p>Same for all two other places i'm writing to the file.
If i will make it all false not to appen when writing it will write one line each time and will overwrite the line.
But if i'm doing true it will append many Api lines or many UserId lines.
And i want each to time to replace the line with the textBox to overwrite only on this line but with the new text.</p>
<p>If in cTextBox1 there is the text: Hello World
Then i changed it to: Hello World Now
Then replace the Api line Hello World with Hello World Now</p>

<p>The first thing I tried was using a CNAME record in Route 53 straight from my domain onto the domain that I got from the API Gateway. That was returning some errors and I think it is the incorrect solution is that correct?</p>
<p>Next I tried the Custom Domain Names feature in API Gateway. My understanding is this will roll up a CloudFront distribution that I can then map onto from Route 53. When I created the custom domain and added a Domain Mapping it provides me with a url to what I assume is a CloudFront distribution. The link is returning a 403 response and no distribution has been made in CloudFront. What is a good way of debugging this problem?</p>

36,469,631 | How to get Leaflet for R use 100% of Shiny dashboard height | <p>I am in the process of creating a Shiny dashboard application, where the dashboard body is supposed to show some maps. So far no problem to get the map expand over the entire width of the body, but it's somehow not willing to adjust to the full height.

36,472,186 | Abstract methods in Swift? | <p>I have few questions for Swift developers regarding the concept of abstract classes.</p>
<ol>
<li><strong>How do you define an abstract class in Swift?</strong> Is there any way to prevent a class from being instantiated, while providing an initializer for its subclasses to use?</li>
<li><strong>How do you define abstract methods, while implementing others?</strong> When defining abstract methods, Apple generally points you to protocols (interfaces). But they only solve the first part of my question, since <em>all</em> of the methods they define are abstract. What do you do when you want to have both abstract and non-abstract methods in your class?</li>
<li><strong>What about generics?</strong> You might have thought about using protocols together with extensions (categories). But then there is an issue with generics because protocols can't have generic types, only <em>typealiases</em>.</li>
</ol>
<p>I have done my homework and I know about solving these issues using methods, such as <code>fatalError()</code> or <code>preconditionFailure()</code> in the superclass and then overriding them in a base class. But that seems like <em>ugly</em> object design to me.</p>
<p>The reason I'm posting this is to find out whether there exists more general and universal solution.</p>

36,477,444 | Java Object return type vs. Generic Methods | <p>I saw several questions about generic return type, but none answers my question.
<br>If there is no bound for any of the arguments, such as the following method in <a href="https://github.com/jayway/JsonPath/blob/master/json-path/src/main/java/com/jayway/jsonpath/JsonPath.java">JayWay</a> :</p>
<pre><code>public static <T> T read(String json, String jsonPath, Filter... filters) {
return new JsonReader().parse(json).read(jsonPath, filters);
}
</code></pre>
<p>What is the point of using this as generic ?<br>
I told the guys from my team that this method should be used as :</p>
<pre><code>JsonPath.<Boolean>read(currentRule, "$.logged")
</code></pre>
<p>instead of:</p>
<pre><code>(boolean) JsonPath.read(currentRule, "$.logged")
</code></pre>
<p>But I really can't tell the difference...</p>

36,478,901 | Switching from native iOS gui to Qt gui | <p>I currently have a native iOS GUI and a Qt-GUI. I'm trying to switch from one to another.</p>
<p>To be clear: When i click on a button on the native GUI i want the Qt-GUI to show up and vice versa.</p>
<p>I already found out which libraries i have to add to be able to use the Qt-Stuff. I created a <code>QApplication</code> in the <code>AppDelegate.mm</code> file:</p>
<pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *) launchOptions {
// receive int argc, and char** argv for the QApplication.
_qApp = new QApplication(_argc, _argv);
}
</code></pre>
<p>Furthermore my Qt application looks (at the moment) like this:</p>
<pre><code>void createQtGUI() {
QPushButton* btn = new QPushButton("Some Button");
QLabel* lbl = new QLabel("QTGui");
QVBoxLayout* layout = new QVBoxLayout();
layout->addWidget(lbl);
layout->addWidget(btn);
QWidget* window = new QWidget();
window->setLayout(layout);
window->show();
}
</code></pre>
<p>I'm calling the <code>createQtGUI</code> method in my <code>ViewController.mm</code> when pressing a button in the native iOS GUI. The code runs without throwing any error, but:</p>
<p><strong>The Qt-GUI is not shown. The application still shows the native gui without switching to the Qt-GUI.</strong></p>
<p>Has anybody got any idea how to fix that?</p>

36,479,963 | The number of registers in CUDA CC 5.0? | I have a GeForce GTX 745 (CC 5.0).
The deviceQuery command shows that the total number of registers available per block is 65536 (65536 * 4 / 1024 = 256KB)
I wrote a kernel that uses an array of size 10K and the kernel is invoked as following.
I tried two ways to allocated the array:
// using registers
fun1() {
short *arr = new short[100*100]; // 100*100*sizeof(short)=256K / per thread
....
delete[] arr;
}
fun1<<<4, 64>>>();
// using global memory
fun2(short *d_arr) {
...
}
fun2<<<4, 64>>>(d_arr);
I can get the correct result in both manner.
The first one which uses registers runs much faster.
But when invoking the kernel using 6 blocks i got the wrong answer.
fun1<<<6, 64>>>();
Now i'm wondering actually how many of registers can i use? And how is it related to the number of blocks ?

36,484,888 | How to return a pointer to an object? | <p>I have created two classes one called Pair(as data members has a dynamically allocated array of chars for KEY and double for value) and the other Collection(which is a collection of Pairs, as data members it has a dynamically allocated array of pairs, and a int variable for the sizeOfPairs). The Collection class should have a method that should return a pointer to the first objects with the provided key, if such object does not exist returns NULL pointer. This is how far I got with that method, but I get an error(error: indirection requires pointer operand ('Pair' invalid)) for the 4th line. Is the way I am returning a pointer to an object correct?</p>
<pre><code>Pair *find(const char *key){
for(int i = 0; i < sizeOfPair; ++i){
if(pair[i].getKey() == key){
return *pair[i];
}else{
return NULL;

36,485,069 | C++ Easiest Way to sort and read this file? | <p>This file seems a bit... awkward to manage. I need to sort the file by the highest score and here is a small sample of the file at hand:</p>
<pre><code>reece 0

<p>Just a few bits of the data. Basically I need it sorted in the following arrangement and then wrote back to the original file:</p>
<pre><code>john 5
alex 2
reece 0
</code></pre>
<p>This also needs to be possible with an infinite amount of data (not inf but you understand what I mean). I have tried this:</p>
<pre><code>void read() {
vector<string> arr;
string a, b;
ifstream file1;
file1.open("Scores.txt", ios::out);
int count = 0;
while (file1 >> a >> b) {
string toVec = a + b;
arr.push_back(toVec);
count++;
}
for (int outLoop = 0; outLoop < count; outLoop++) cout << arr[outLoop];
}
</code></pre>
<p>Now this reads from the file and put them into a vector but I don't know what to do from that point. The cout just shows this:</p>
<pre><code>reece0john5alex2
</code></pre>
<p>How would I go about splitting that up and sorting it?</p>

The requirement is to write the copy function.
But when I finish this function as my opinion the new list only contains one item or None item.
Does anyone could tell me how to finish this function?
