Visual thinking

Designer Jason Santa Maria continues his excellent Under The Loupe series with a post about visual thinking. This one's got some great ideas to get your creative juices going.

Strong concepts don't always just come to us; sometimes they take work. Perhaps not real physical labor, but a process of bypassing the obvious ideas to get to the hidden ones. Some people call this "Creative Thinking", but when I was first introduced to this concept, it was presented to me as "Visual Thinking". I tend to prefer "Visual" as opposed to "Creative" as it helps to shift the focus back to design specifically. Let's define "Visual Thinking" as: A process of idea-finding and formulation, typically with simple tools like a pencil and paper, where the cumulation of ideas influences the whole.

Add a method

Use the add method wizard to add a method to an interface in your project. If the project contains a class associated with the interface, the wizard also adds the method to the class.

Add a method to your interface:

From the Visual Studio main menu, choose View > Class view . In the Class View pane, expand the project node to display the interface you want to add the method to.

You can also add methods to dispinterfaces. Unless the project is attributed, dispinterfaces are located under the library node.

Right-click the name of the interface.

On the shortcut menu, choose Add > Add Method .

In the Add Method wizard dialog box, provide the information to create the method as described in the next section.

Select OK to add the method.

Add method wizard

Add a method to an interface by using the add method wizard:

Method name

Provide the method name.

Return type

Type the return type or select it from the drop-down list.

Displays the method's parameters, modifiers, and types. The wizard updates the Parameters list as you add parameters.

Add a parameter. In Parameters , type the parameter type, name, and any modifiers. For example, int x , and choose OK .

Is there a shortcut in VisualStudio to create a method?

Is there a shortcut in VisualStudio to create a method, like there is "prop, tab" for a property and "ctor, tab" for a constructor?

There is no Code snippe t to create a method other than Main , but you can do the following.

Type your to be method name, pass the parameters, Once done you will notice a blue under line at the beginning of method name. Click that (or click Ctrl + . ) that will give you the option to create method like:

This will generate a method like:

There is another clever way for create method (extract).

This way I use if I have method and I would like part of this method move to new private method.

This will create only new private method but automatically set input parameters and output parameter.

check Code Snippets

sim: static int main method

svm: static void main method

Save the following Code snippet into a file with '.snippet' extension

<?xml version="1.0" encoding="utf-8"?> <CodeSnippets xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet"> <CodeSnippet Format="1.0.0"> <Header> <Title>Generate Method Stub</Title> <Description>Create a new method</Description> <Author>Anoop Simon</Author> <Shortcut>stub</Shortcut> </Header> <Snippet> <Code Language="CSharp"> <![CDATA[public string DummyMethod(string arg1,string arg2) { return string.Empty; } ]]> </Code> </Snippet> </CodeSnippet> </CodeSnippets>

Open Visual Studio .

Import the file saved earlier

Here is a guidelines to create custom code snippet .

You can make your own code snippet, or just use this template:

after you import this snippet to your visual studio, when you press emptymethod + tab , you will get new not implemented method.

Type 'fun' then tab. Ta-da! And now I need to type more characters because the minimum allowed number of characters is 30.

Visual Basic Methods / Functions

In visual basic, Method is a separate code block that will contain a series of statements to perform particular operations.

Generally, visual basic Methods are useful to improve the code reusability by reducing code duplication. Suppose, if we have the same functionality to perform in multiple places, we can create one method with the required functionality and use it wherever required in the application.

Syntax of Visual Basic Methods

In visual basic, we can create the Methods either by using Sub or Function keywords like as shown below. If we create a method with Sub keyword that will not allow us to return any value. If you want to return any value, you need to use Function keyword to create the method.

If you observe the above syntax, we can create a method either by using Sub or Function keyword based on our requirements.

The following table lists the parameter details we specified while creating the methods.

The following are examples of defining the different methods in a visual basic programming language.

If you observe the above examples, we defined different methods with different access modifiers, return types, and different parameters based on our requirements.

Now, we will see the complete example of using the methods in the visual basic programming language.

Visual Basic Methods Example

Following is the example of using the methods in a visual basic programming language.

If you observe the above example, we created two methods ( GetDetails , GetUserDetails ) with/without parameters and performing required operations.

We will get the following result when we execute the above visual basic program.

Visual Basic Methods or Functions Example Result

This is how we can use the methods in visual basic applications based on our requirements.

Generate Method Stubs using Shortcut Key in Visual Studio

Ctrl + .” Or “ALT + SHIFT+F10” is one of the very useful shortcut key in Visual Studio. You can use that shortcut key to generate the methods stubs. Like, If you want to create method which will add to number, you can write like AddTwoNumber() and press “Ctrl+.” and Enter to generate the Stub for your methods automatically

The most interesting point it will generate the stubs based on the type of argument we are giving. As shown in below picture for first arguments its generated integer and for second its generated string.

also, this will work for return type as well.

Yes, this tip will surely speed up your coding.

You can use the same key for different purpose as well. Here is one of my blog post, which you may found interesting

Create Method Implementations

expand all | collapse all

Create Method Implementations provides C/C++ users with an efficient mechanism for creating implementation stubs for all of the methods in a class declaration. (Create Method Implementations is similar to Create Implementation, which can be invoked from the declaration of a single method.)

With Create Method Implementations, parameters between declarations and implementations are certain to be consistent, and the format of the implementations will be consistent with user preferences.

The following example is of a class declaration in C++ whose methods can be implemented.

Move to a class declaration and select Create Method Implementations from a refactoring menu, e.g. the Quick Action and Refactoring menu (Shift+Alt+Q).

Select the methods to implement.

Implementations are created in the appropriate source file if it can be found, e.g. MyClass.cpp for MyClass.h. If not, implementations are created below the declaration, and can be moved manually.

Existing Implementations

If a method is already implemented, it is excluded from the selection dialog.

In the following example, Bar() is excluded.

Format of Implementations

Modify the format of newly created implementations, e.g. to remove spacing around parentheses, by editing the VA Snippet for Create Implementation. There are separate VA Snippets for separate languages.

The following is the default VA Snippet for Create Implementation in C++.

Location of Implementations

By default, Visual Assist places new implementations near those of neighboring declarations. Alternatively, Visual Assist can create implementations at the EOF of a source file. Specify your preference in the options dialog for Visual Assist.

Visual Studio Shortcut Keys

In this article you will learn about some Visual Studio Shortcuts.

This is in continuation with article 1 where I discussed about how one can be more productive with Visual Studio. In article 1, we discussed some shortcuts that helps a lot while writing and reviewing code in day to day work. While writing code we need to follow certain rules and constructs that also becomes very repetitive. For example, you are writing classes for your domain or adding properties or defining constructors or putting try block and lot more where we just need to write the code in similar pattern. Spending time in these types of codes are waste of time and energy. To see my previous article 1, here's the link:

Developer Productivity By Visual Studio Shortcuts

In this article, I am going to discuss some more tricks that can insert code snippets just by few keystrokes.

Some other tips and tricks:

Printing in C# Made Easy

Refactoring

Source code refactoring can improve the quality and maintainability of your project by restructuring your code while not modifying the runtime behavior. Visual Studio Code supports refactoring operations (refactorings) such as Extract Method and Extract Variable to improve your code base from within your editor.

For example, a common refactoring used to avoid duplicating code (a maintenance headache) is the Extract Method refactoring, where you select source code that you'd like to reuse elsewhere and pull it out into its own shared method.

Refactorings are provided by a language service and VS Code has built-in support for TypeScript and JavaScript refactoring through the TypeScript language service. Refactoring support for other programming languages is provided through VS Code extensions that contribute language services. The UI and commands for refactoring are the same across languages, and in this topic we'll demonstrate refactoring support with the TypeScript language service.

Code Actions = Quick Fixes and refactorings

In VS Code, Code Actions can provide both refactorings and Quick Fixes for detected issues (highlighted with green squiggles). An available Code Action is announced by a lightbulb near the source code when the cursor is on a squiggle or selected text region. Clicking on the Code Action lightbulb or using the Quick Fix command ⌘. (Windows, Linux Ctrl+. ) will display Quick Fixes and refactorings.

If you'd just like to see refactorings without Quick Fixes, you can use the Refactor command ( ⌃⇧R (Windows, Linux Ctrl+Shift+R ) ).

Note: If you prefer to not see the Code Action lightbulb in your editor, you can disable lightbulbs with the editor.lightbulb.enable setting . You can still open Quick Fixes through Quick Fix command and ⌘. (Windows, Linux Ctrl+. ) keyboard shortcut.

Refactoring actions

Extract method.

Select the source code you'd like to extract and then click on the lightbulb in the gutter or press ( ⌘. (Windows, Linux Ctrl+. ) ) to see available refactorings. Source code fragments can be extracted into a new method, or into a new function at various different scopes. During the extract refactoring, you will be prompted to provide a meaningful name.

Extract Variable

TypeScript language service provides Extract to const refactoring to create a new local variable for the currently selected expression:

When working with classes, you can also extract a value to a new property.

Rename symbol

Renaming is a common operation related to refactoring source code and VS Code has a separate Rename Symbol command ( F2 ). Some languages support rename symbol across files. Press F2 and then type the new desired name and press Enter . All usages of the symbol will be renamed, across files.

Keybindings for Code Actions

The editor.action.codeAction command lets you configure keybindings for specific Code Actions. This keybinding, for example, triggers the Extract function refactoring Code Actions:

Code Action kinds are specified by extensions using the enhanced CodeActionProvided API. Kinds are hierarchical, so "kind": "refactor" will show all refactoring Code Actions, whereas "kind": "refactor.extract.function" will only show Extract function refactorings.

Using the above keybinding, if only a single "refactor.extract.function" Code Action is available, it will be automatically applied. If multiple Extract function Code Actions are available, we bring up a context menu to select them:

You can also control how/when Code Actions are automatically applied using the apply argument:

Valid values for "apply" :

When a Code Action keybinding is configured with "preferred": true , only preferred Quick Fixes and refactorings are shown. A preferred Quick Fix addresses the underlying error, while a preferred refactoring is the most common refactoring choice. For example, while multiple refactor.extract.constant refactorings may exist, each extracting to a different scope in the file, the preferred refactor.extract.constant refactoring is the one that extracts to a local variable.

This keybinding uses "preferred": true to create a refactoring that always tries to extract the selected source code to a constant in the local scope:

Extensions with refactorings

You can find extensions that support refactoring by looking in the VS Code Marketplace . You can go to the Extensions view ( ⇧⌘X (Windows, Linux Ctrl+Shift+X ) ) and type 'refactor' in the search box. You can then sort by install count or ratings to see which extensions are popular.

Tip: The extensions shown above are dynamically queried. Click on an extension tile above to read the description and reviews to decide which extension is best for you.

Common questions

Why don't i see any lightbulbs when there are errors in my code.

Lightbulbs (Code Actions) are only shown when your cursor hovers over the text showing the error. Hovering over the text will show the error description, but you need to move the cursor or select text to see lightbulbs for Quick Fixes and refactorings.
