Interfaces in Dynamics 365 FO

Interfaces Overview in AX 2012

You create an interface under the Classes node of the AOT. Defining an interface is similar to creating a new class. An interface definition has two components: the declaration and the body.

X++

interfaceDeclaration

{

    #interfaceBody

}

The interface declaration declares various attributes about the interface, such as its name and whether it extends another interface. The interface body contains the method declarations within the interface as shown in the following example.

X++

interface SysDeleteTables

{

    public void doDeleteCustomerTables();

}

Using an Interface

To use an interface, write a class that implements the interface. When a class implements an interface, the class must provide a method implementation for all of the methods declared within the interface as shown in the following example.

class SysDataImport extends SysDataExpImp implements sysDeleteTables

{

// Supply implementation of methods in the interface.

void doDeleteCustomerTables()

{

// Implement the method.

}

}

A class that implements an interface inherits all the method declarations in that interface. However, the class needs to provide bodies for those methods.

Example of Interface

interface IDrivable

{

    int getSpeed()

    {

    }

    void setSpeed(int newSpeed)

    {

    }

}

class Automobile implements IDrivable

{

    int speed;

    public int getSpeed()

    {

        return speed;

    }

    public void setSpeed(int newSpeed)

    {

        speed = newSpeed;

    }

}

class UseAnAutomobile

{

    void DriveAutomobile()

    {

        IDrivable drivable;

        Automobile myAutomobile = new Automobile();

        str temp;

        myAutomobile = new Automobile();

        if (myAutomobile is IDrivable)

        {

            drivable = myAutomobile;

            drivable.setSpeed(42);

            temp = int2str(drivable.getSpeed());

        }

        else

        {

            temp = "Instance is not an IDrivable.";

        }

        info(temp);

    }

}

PostLoad() method in AX tables Dynamics 365 FO

PostLoad() is the method that is used to read records from the database and you can perform any custom logic by overriding this method on any table.

public void postLoad()

{

    super();

    if (this.Name == 'MEL')

        this.Value = 5;

}

Getting an error while performing Get Latest Version in Visual studio in Dynamics 365 FO

 Error message:

Multiple errors occurred during the operations, the first of which is displayed below. A full error list is available in the Output Window. Access is denied.

Finally, stopping AOS services (IIS) and world wide services, and W3C in the development machine and performing “Get latest version” worked for me. However, I’m not sure of the root cause of the issue, but I assume some of the objects are not allowed to overwrite when they are in use.

Intelli sense in VS

How to turn on/Trigger Intelli Sense in Visual Studio in Dynamics 365 FO

What is Intelli sense?

IntelliSense in Visual Studio is a feature that helps programmers write code faster and with fewer mistakes. Here's how it simplifies coding:

1. Auto-completion: 

It suggests how to finish lines as you type, so you don't have to type everything.

2. Helps with errors: 

It points out mistakes as you go, helping you fix them right away.

3. Shows useful info: 

It gives quick pop-ups with info about codes, like what a function does or what parameters it needs.

4. Easy to use: 

It lists options you can use in your code, making it easier to remember what commands are available.

Overall, IntelliSense is like a smart assistant that helps you code by giving hints and fixing mistakes along the way.

How to turn on/trigger Intelli sense?

Open visual studio, go to any code

and press Ctrl + Space
