Using named ranges allows you to describe the meaning of a cell(s) contents and use this defined name in place of an actual cell address. For example, formula =A5*B5 can be replaced with =Width*Height to make the formula much easier to read and understand. To define a new named range, select cell ...

Create new named range called ‘MyRange’ assigned to cell A1 ThisWorkbook.Names.Add Name:="MyRange", _ RefersTo:=Worksheets("Sheet1").Range("A1") Delete defined named range by name ThisWorkbook.Names("MyRange").Delete Access Named Range by name...

Formulas tab > Defined Names group > Name Manager button Named Manager allows you to: Create or change name Create or change cell reference Create or change scope Delete existing named range Named Manager provides a useful quick look for broken links.

A natural division is simply to make one topic for each language feature. For instance, Python has: Classes Functions Generators Decorators . . . On the downside, features can be quite complicated and it's easy to come up with many more examples than make sense for a single page. Classes h...

Windows provides an explicit interface through which the winsound module allows you to play raw beeps at a given frequency and duration. import winsound freq = 2500 # Set frequency To 2500 Hertz dur = 1000 # Set duration To 1000 ms == 1 second winsound.Beep(freq, dur)

Using immutable locals: Uses less horizontal space but more vertical space than the "anonymous temporaries" template. Preferable over the "anonymous temporaries" template if the when expression is in a loop--in that case, regex definitions should be placed outside the loop. im...

Some topics are loosely associated examples under a theme, such as C# 6.0 Features and Common pitfalls. On the whole, this style of topic has been discouraged since examples per topic were limited as there's no natural place to stop adding content. It's probably better to move the examples to anoth...

CREATE TABLE mytable (number INT); INSERT INTO mytable VALUES (1); CREATE MATERIALIZED VIEW myview AS SELECT * FROM mytable; SELECT * FROM myview; number -------- 1 (1 row) INSERT INTO mytable VALUES(2); SELECT * FROM myview; number -------- 1 (1 row) REFRESH ...

This example demonstrates how to develop a simple UWP application. On creation of a "Blank App (Universal Windows)" project there are many essential files that are created in your solution. All files in your project can be seen in the Solution Explorer. Some of the crucial files in your...

Once you got a collection object, queries use the same syntax as in the mongo shell. Some slight differences are: every key must be enclosed in brackets. For example: db.find({frequencies: {$exists: true}}) becomes in pymongo (note the True in uppercase): db.find({"frequencies": ...

Let's say you need to add a field to every document in a collection. import pymongo client = pymongo.MongoClient('localhost', 27017) db = client.mydb.mycollection for doc in db.find(): db.update( {'_id': doc['_id']}, {'$set': {'newField': 10} }, upsert=False, multi=False...

This approach was introduced in JSR 286. In JSR 168,render parameters set in processAction of a portlet were available only in that portlet.With the Public Render Parameters feature, the render parameters set in the processAction of one portlet will be available in render of other portlets also.In ...

This is one approach which has been there since JSR 168.It allows us to share attributes using portlet session.A portlet session can have different types of scopes: Portlet scope(attributes available only within portlet) Application scope(attributes available within whole application[war]) In...

The eventing mechanism is an extended version of the public render param,with additonal feature to pass custom objects to other portlets,but with an overhead of event phase. To achieve this,this mechanism consists of Publisher portlet Processor(consumer) portlet,where both may be part of differ...

Temp tables must have unique IDs (within the session, for local temp tables, or within the server, for global temp tables). Trying to create a table using a name that already exists will return the following error: There is already an object named '#tempTable' in the database. If your query pro...
