Lets say you want to filter a query by two columns, but only certain combinations of those columns. For example, it's OK to have account 60400 with reference JE, but you cannot have account 60400 with reference ED, but you can have account 60500 with reference ED. select * from schema.table where ...

ValueExpression ve = AdfmfJavaUtilities.getValueExpression(<binding>, String.class); String <variable_name> = (String) ve.getValue(AdfmfJavaUtilities.getELContext()); Here "binding" indicates the EL expression from which the value is to be get. "variabl...

ValueExpression ve = AdfmfJavaUtilities.getValueExpression(<binding>, String.class); ve.setValue(AdfmfJavaUtilities.getELContext(), <value>); Here "binding" indicates the EL expression to which the value is to be stored. "value" is the desired val...

AdfELContext adfELContext = AdfmfJavaUtilities.getAdfELContext(); MethodExpression me; me = AdfmfJavaUtilities.getMethodExpression(<binding>, Object.class, new Class[] { }); me.invoke(adfELContext, new Object[] { }); "binding" indicates the EL expression from wh...

max-width is the breakpoint @media (max-width: 1200px) { .navbar-header { float: none; } .navbar-left,.navbar-right { float: none !important; } .navbar-toggle { display: block; } .navbar-collapse { border-top: 1px solid transpar...

There are three modes of XAML bindings exists for either Binding and x:Bind: OneTime: Update happens only once, on initialization of the view during InitializeComponent() call. (ViewModel[sends data when initializing] -> View) OneWay: View is updated when ViewModel changes. But not in the rev...

When calling methods directly from the view. If performance matters really bad (scientific spaceship stuff) When you want to get compile time errors

Use it if you want to be flexible about the source type of your data. It won't bind to an actual property but to its name. If you want to bind to the DataContext

OpenCL is low level api so it must be implemented in "C space" first. For that, one needs to download header files from Khronos' site. My hardware is AMD and capable of version 1.2, downloading opencl.h cl_platform.h cl.h cl_ext.h cl_egl.h cl_dx9_media_sharing.h cl_d3d10.h c...

Assuming you know the productID: First import StoreKit Then in your code let productID: Set = ["premium"] let request = SKProductsRequest(productIdentifiers: productID) request.delegate = self request.start() and in the SKProductsRequestDelegate: func productsRequest(request: ...

Image img = new Image(); BitmapImage bitmap = new BitmapImage(new Uri("ms-appx:///Path-to-image-in-solution-directory", UriKind.Absolute)); img.Source = bitmap;

<a data-bind="attr: { href: myUrl }">link with dynamic href</a> ko.applyBindings({ myUrl: ko.observable("http://www.stackoverflow.com") }); Since there is no native href binding in KnockoutJS, you need to use a different feature to get dynamic links. The abo...

href binding is not native to KnockoutJS, so to get dynamic links use a custom binding handler: <a data-bind="href: myUrl">link with dynamic href</a> ko.bindingHandlers['href'] = { update: function(element, valueAccessor) { element.href = ko.utils.unwrapObservable(v...

In image processing applications, the bilateral filters are a special type of non-linear filters. There is a trade off between loosing structure and noise removal, because the most popular method to remove noise is Gaussian blurring which is not aware of structure of image; therefore, it also remov...

This example attempts to mimic the behavior of the built-in path construction operators like arc. If there is a current point, poly first draws a line to (x,y)+(r,0), otherwise it starts by moving to that point. Instead of gsave ... grestore (which has the undesirable effect of discarding the very...

Create an instance of Mobile Analytics for Bluemix. Add the Bluemix Mobile Services SDK to your iOS project. After installing the SDK, add these import statements at top of your AppDelegate.swift file: import BMSCore import BMSAnalytics Next you'll need to initialize and send mobile ana...

Lets say you have a simple ApiController like this: [HttpGet] [Route("test")] public dynamic Test() { dynamic obj = new ExpandoObject(); obj.prop1 = "some string"; obj.prop2 = 11; obj.prop3 = "another string"; ...

The leader key could be used as a way to create a mapping with a key-binding that can be overridden by the end user. The leader is the \ key by default. In order to override it, the end-user would have to execute :let g:mapleader='somekey(s)' before defining the mapping. In a typical scenario, the...

This ability was added to the Bind markup extension after v1607 (Redstone 1). You can specify a function path, as well as arg paths and constant args. Let's assume we have a function defined in our backcode: public string Translate(string text, string from, string to) Now we can use bind to eva...

This UNION ALL combines data from multiple tables and serve as a table name alias to use for your queries: SELECT YEAR(date_time_column), MONTH(date_time_column), MIN(DATE(date_time_column)), MAX(DATE(date_time_column)), COUNT(DISTINCT (ip)), COUNT(ip), (COUNT(ip) / COUNT(DISTINCT (ip))) AS Ratio ...
