HSetMemo (Function)

Used to modify the management mode of memo items. You have the ability to manage all the memos of a data file or a specific memo item of a data file. The management of memos is enabled by default.

The management of memos can be implemented for the data file only: the memos cannot be managed for the items.

When HSetMemo is called, all started iterations are closed. The filter and search criteria are kept.

Syntax

<Result> = HSetMemo([<Data file> [, <Memo item>, ]] <Management mode>)

<Result>: Integer

Old memo management mode used (before calling HSetMemo).
hMemoAuto
(default value) The memos are read during the access to the item.
hMemoNo No management of memos (no read or write operation will be performed on the data file or in the specified item).
hMemoYes The text memos are read whenever the record is read.
The binary memos are read during the access to the item.

<Data file>: Optional character string

Name of the data file used.
If this name is not specified or if it is equal to "*", all the memo files are taken into account.

<Memo item>: Optional character string

Name of the memo item to manage or not.
If this name is not specified or if it is equal to "*", all the memo items are taken into account.
The management of memos can be implemented for the data file only: the memos cannot be managed for the items.

<Management mode>: Integer constant

Management mode of the memo items:
hMemoAuto
(default value) The memos are read during the access to the item.
hMemoNo No management of memos (no read or write operation will be performed on the data file or in the specified item).
hMemoYes The text memos are read whenever the record is read.
The binary memos are read during the access to the item.

If only this parameter is specified, the management mode is applied to all the data files and to all the items.
The hMemoAuto constant is equivalent to the hMemoYes constant.
