VaultSetSize Event

Fires to resize a callback mode vault.


public event OnVaultSetSizeHandler OnVaultSetSize;

public delegate void OnVaultSetSizeHandler(object sender, CbvaultVaultSetSizeEventArgs e);

public class CbvaultVaultSetSizeEventArgs : EventArgs {
  public long VaultHandle { get; }
  public long NewSize { get; }
  public int ResultCode { get; set; }
Public Event OnVaultSetSize As OnVaultSetSizeHandler

Public Delegate Sub OnVaultSetSizeHandler(sender As Object, e As CbvaultVaultSetSizeEventArgs)

Public Class CbvaultVaultSetSizeEventArgs Inherits EventArgs
  Public ReadOnly Property VaultHandle As Long
  Public ReadOnly Property NewSize As Long
  Public Property ResultCode As Integer
End Class


This event fires when the component needs to resize the callback mode vault specified by VaultHandle.

This event only needs to be handled if the CallbackMode property is enabled; please refer to the Callback Mode topic for more information. To handle this event properly, applications must grow or shrink the vault specified by VaultHandle in order to reach the specified NewSize. When growing a vault, applications do not need to sanitize newly-allocated space.

The VaultHandle parameter contains an application-defined handle to an open callback mode vault, as returned by the application in an earlier VaultOpen event.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.

Note: An application should not attempt to call component's methods from handlers of this event. Doing this is guaranteed to cause a deadlock.

Note: when a storage is opened concurrently in read-only mode by several applications using CBDrive or CBMemDrive component, the event will fire only in the first application. To prevent such a situation, always open a vault in read-write mode.
