# Database Form Events

The Events tab page, allows you to assign a macro to certain events which occur in a database form.

이 명령을 사용하려면...

Open context menu of a selected form element - choose Form Properties - Events tab.

Open Form Design toolbar, click Form Properties icon - Events tab.

이벤트를 매크로와 연결하려면 먼저 이벤트가 발생할 때 실행할 모든 명령이 포함된 매크로를 작성합니다. 그런 다음, 각 이벤트 옆의 ... 버튼을 클릭하여 해당 이벤트에 이 매크로를 할당합니다. 매크로를 선택할 수 있는 매크로 할당 대화 상자가 열립니다.

다음의 실행은 사용자가 임의대로 구성할 수 있습니다. 즉, 사용자는 사용자 정의 대화 상자를 사용하여 실행을 표시할 수 있습니다:

1. 오류 메시지 표시,

2. (데이터 레코드의) 삭제 과정 확인 ,

3. 매개 변수 쿼리,

4. 데이터 레코드 저장시 입력 검사.

예를 들어 데이터 레코드를 삭제할 때 "고객 xyz를 정말 삭제하시겠습니까?"와 같이 "삭제 확인" 요청 메시지를 표시할 수 있습니다.

The events that are shown in the Events dialog cannot be edited directly. You can remove an event from the list by pressing the Del key.

양식에서 매크로와 연결할 수 있는 모든 이벤트는 다음과 같습니다.

## 레코드 변경하기 전에

The Before record change event occurs before the current record pointer - SQL cursor - is changed. Return True when moving is allowed, otherwise False.

## 레코드 변경한 후에

The After record change event occurs directly after the current record pointer has been changed.

## 레코드 실행 이후에

The After record action event occurs directly after the current record has been changed.

## 레코드 실행 전에

The Before record action event occurs before the current record or record set are changed. Return True when changing is allowed, otherwise False. For example, the linked macro can request confirmation in a dialog.

## 로드할 때

The When loading event occurs directly after the form has been loaded.

## 매개 변수 채우기

The Fill parameters event occurs when the form to be loaded has parameters that must be filled out. For example, the data source of the form can be the following SQL command:

SELECT * FROM address WHERE name=:name

Here :name is a parameter that must be filled out when loading. The parameter is automatically filled out from the parent form if possible. If the parameter cannot be filled out, this event is called and a linked macro can fill out the parameter. Return True when the execution of the parametrized statement should continue, False otherwise.

## 삭제 확인

The Confirm deletion event occurs as soon as data has been deleted from the form. Return True to allow row deletion, False otherwise. For example, the linked macro can request confirmation in a dialog.

## 새로 로드하기 전에

The Before reloading event occurs before the form is reloaded. The data content has not yet been refreshed.

## 새로 로드할 때

The When reloading event occurs directly after the form has been reloaded. The data content has already been refreshed.

## 언로드하기 전에

The Before unloading event occurs before the form is unloaded; that is, separated from its data source.

## 언로드할 때

The When unloading event occurs directly after the form has been unloaded; that is, separated from its data source.

## 업데이트하기 전에

The Before update event occurs before the control content changed by the user is written into the data source. The linked macro can, for example, prevent this action by returning FALSE.

## 업데이트한 후에

The After update event occurs after the control content changed by the user has been written into the data source.

## 원래대로 설정하기 전에

The Prior to reset event occurs before a form is reset. Returning True approves the reset, returning False cancels the operation.

다음 조건 중 하나가 나타날 경우 양식은 다시 설정됩니다.

1. 사용자가 원래대로 버튼으로 정의되어 있는 (HTML) 버튼을 누릅니다

2. 데이터 원본에 연결되어 있는 양식에 비어 있는 새 레코드를 만듭니다. 예를 들어 마지막 레코드에서 다음 레코드 버튼을 누를 수 있습니다.

## 원래대로 설정한 후에

The After resetting event occurs after a form has been reset.

## 오류 발생

The Error occurred event is activated if an error occurs when accessing the data source. This applies to forms, list boxes and combo boxes.

## 전송하기 전에

The Before submitting event occurs before the form data is sent. Returning True approves the submission, False stops it.

## Vetoable events

Macros can interrupt event execution when they return a boolean value: True allows the execution of the event to continue and False stops the event execution.

The following events are interruptable by returning False:

- Before record action

- Before record change

- Before submitting

- Before update

- Fill parameters
