Progress indicator (Progress bar) in Dynamics 365 Business Central

Hello Everyone.
Have you ever encountered a step that takes a long time to execute when running Business Central customized features?
It is recommended to add a progress indicator to display the progress. You can run it in the foreground to have a better clarity of it and even close it while it is running.
So how to do it.
I will give two type of examples: Action in page and Report.

Actions:
Example 01:

            action(ProgressIndicator)
            {
                Caption = 'Progress Indicator';
                ApplicationArea = All;
                Image = Calculate;

                trigger OnAction()
                var
                    Progress: Dialog;
                    Counter: Integer;
                    Text000: Label 'Counting to 100 ------ #1';
                begin
                    Counter := 0;
                    Progress.OPEN(Text000, Counter);
                    REPEAT
                        // Do some processing.  
                        Counter := Counter + 1;
                        Progress.UPDATE(); // Update the field in the dialog.
                        SLEEP(50);
                    UNTIL Counter = 100;
                    Progress.CLOSE()
                end;
            }

Example 02:

            action(ProgressIndicator)
            {
                Caption = 'Progress Indicator';
                ApplicationArea = All;
                Image = Calculate;

                trigger OnAction()
                var
                    Progress: Dialog;
                    Counter: Integer;
                    ProgressMsg: Label 'Processing......#1######################\';
                begin
                    Clear(Counter);
                    if not GuiAllowed then
                        exit;
                    Progress.Open(ProgressMsg);
                    // Do some processing
                    for Counter := 1 to 100 do begin
                        Progress.Update(1, Counter);// Update the field in the dialog.
                        Sleep(50);
                    end;
                    Progress.Close();
                end;
            }

Example 03:

            action(ProgressIndicator)
            {
                Caption = 'Progress Indicator';
                ApplicationArea = All;
                Image = Calculate;

                trigger OnAction()
                var
                    Progress: Dialog;
                    Counter: Integer;
                    ProgressMsg: Label 'Progress from 0 to 9999   #1#####';
                begin
                    Counter := 0;
                    Progress.OPEN(ProgressMsg, Counter);
                    REPEAT
                        // Do some processing.  
                        Counter := Counter + 1;
                        Progress.UPDATE(); // Update the field in the dialog. 
                        SLEEP(50);
                    UNTIL Counter = 9999;
                    Progress.CLOSE()
                end;
            }

If it takes a long time to complete, you can click “Cancel” to stop it.

PS:
In Business Central 14 and previous versions, you can use the “@1” to display the progress bar to show the percentage in windows client.

Report:
Example 01:

report 50100 ProgressIndicator
{
    Caption = 'Progress Indicator';
    UsageCategory = Administration;
    ApplicationArea = All;
    ProcessingOnly = true;

    dataset
    {
    }
    trigger OnPreReport()
    var
    begin
        Clear(Counter);
        if not GuiAllowed then
            exit;
        Progress.Open(ProgressMsg);
    end;

    trigger OnPostReport()
    var
    begin
        // Do some processing
        for Counter := 1 to 100 do begin
            Progress.Update(1, Counter);// Update the field in the dialog.
            Sleep(50);
        end;
        Progress.CLOSE()
    end;

    var
        Progress: Dialog;
        Counter: Integer;
        ProgressMsg: Label 'Processing......#1######################\';
}
