Here is an example of usage with a database. On the page where the CAPTCHA will be shown you'll have something like this: $this->load->helper('captcha'); $vals = array( 'img_path' => './captcha/', 'img_url' => 'http://example.com/captcha/' ); $cap = create_captc...

It's a common request to be able to handle a double-click on a row in a RadGridView. The solution proposed by Telerik (http://demos.telerik.com/silverlight/#GridView/ClickEvents ) is based around code behind: this.grid.AddHandler(GridViewCellBase.CellDoubleClickEvent, new EventHandler<RadRouted...

Packages are collections of R functions, data, and compiled code in a well-defined format. Public (and private) repositories are used to host collections of R packages. The largest collection of R packages is available from CRAN. Some of the most popular R machine learning packages are the following...

from sklearn import svm X = [[1, 2], [3, 4]] #Training Samples y = [1, 2] #Class labels model = svm.SVC() #Making a support vector classifier model model.fit(X, y) #Fitting the data clf.predict([[2, 3]]) #After fitting, new data can be classified by using predict()

Intercepted method: public class ExampleService implements Example { @MyAnnotation public doHomework() { System.out.println("working"); } } Annotation: @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD) public @interface MyAnnotation {} ...

These three map functions are equivalent, so use the variation that your team finds most readable. val numberNames = Map(1 -> "One", 2 -> "Two", 3 -> "Three") // 1. No extraction numberNames.map(it => s"${it._1} is written ${it._2}" ) // 2....

Let's say, we have an array: Item = {-1, 0, 3, 6}. We want to construct SegmentTree array to find out the minimum value in a given range. Our segment tree will look like: The numbers below the nodes show the indices of each values that we'll store in our SegmentTree array. We can see that, to sto...

Collection Operators can be used in a KVC key path to perform an operation on a “collection-type” property (i.e. NSArray, NSSet and similar). For example, a common operation to perform is to count the objects in a collection. To achieve this, you use the @count collection operator: self.array = @[@...

Most of the time we like to get the total number of occurrence of a column value in a table for example: TABLE NAME : REPORTS ReportNameReportPriceTest10.00 $Test10.00 $Test10.00 $Test 211.00 $Test10.00 $Test 314.00 $Test 314.00 $Test 4100.00 $ SELECT ReportName AS REPORT ...

public class SimpleLoginMainView extends CustomComponent implements View { public static final String NAME = ""; Label text = new Label(); Button logout = new Button("Logout", new Button.ClickListener() { @Override public void buttonClick(ClickEvent event) { ...

In C++, code must be declared or defined before usage. For example, the following produces a compile time error: int main() { foo(2); // error: foo is called, but has not yet been declared } void foo(int x) // this later definition is not known in main { } There are two ways to resolve...

The following Codes can be found from Weka course Given iris.arff is loaded in weka, inside Weka Explorer's R console or Weka KnowledgeFlow's R Scripting, you can play with the following codes to make beautiful plots: library(ggplot2) ggplot(rdata, aes(x = petallength)) + geom_density() ...

Implement ICloneable in a class with a twist. Expose a public type safe Clone() and implement object Clone() privately. public class Person : ICloneable { // Contents of class public string Name { get; set; } public int Age { get; set; } // Constructor public Person(string...

The implementation of ICloneable for a struct is not generally needed because structs do a memberwise copy with the assignment operator =. But the design might require the implementation of another interface that inherits from ICloneable. Another reason would be if the struct contains a reference t...
