CoreDb.RLock Method

X#
Lock the current record.

Namespace:  XSharp
Assembly:  XSharp.Core (in XSharp.Core.dll) Version: 2.21
Syntax
Copy
 STATIC METHOD RLock(
	uRecId AS Object
) AS LOGIC
Request Example View Source

Parameters

uRecId
Type: Object
The ID (usually a record number) of the record to be locked. If specified, record locks held by the current process are retained. If not specified, all locks held by the current process are released and the current record is assumed.

Return Value

Type: Logic
TRUE if successful; otherwise, FALSE.
Remarks
This function is like DBRlock() but strongly typed.

This function, however, does not call the error handler and will therefore not produce a runtime error message or create an error object if it fails.
Therefore it is important to check the return value to determine if the function succeeded.

The LastRddError property in the runtimestate will contain needed information about any error that occurs.
