Fires after a file or directory is deleted.

Syntax

• C#
• VB.NET

public event OnAfterDeleteFileHandler OnAfterDeleteFile;

public delegate void OnAfterDeleteFileHandler(object sender, CbfilterAfterDeleteFileEventArgs e);

public class CbfilterAfterDeleteFileEventArgs : EventArgs {
  public string FileName { get; }
  public IntPtr FileContext { get; set; }
  public IntPtr HandleContext { get; set; }
  public int ResultCode { get; set; }
}

Public Event OnAfterDeleteFile As OnAfterDeleteFileHandler

Public Delegate Sub OnAfterDeleteFileHandler(sender As Object, e As CbfilterAfterDeleteFileEventArgs)

Public Class CbfilterAfterDeleteFileEventArgs Inherits EventArgs
  Public ReadOnly Property FileName As String
  Public Property FileContext As IntPtr
  Public Property HandleContext As IntPtr
  Public Property ResultCode As Integer
End Class

Remarks

This event fires after the file or directory specified by FileName is deleted. More specifically, this event is fired after the final IRP_MJ_CLOSE IRP is processed by the filesystem (i.e., after the last handle to the file or directory is closed and the file or directory is gone).

Note: This event is not fired when a virtual file is deleted; please refer to the Virtual Files topic for more information.

Applications only need to handle this event if they've added a standard filter rule that includes the FS_CE_AFTER_DELETE flag.

The FileContext and HandleContext parameters are placeholders for application-defined data associated with the file and specific handle, respectively. Please refer to the Contexts topic for more information.

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.

This event is fired synchronously; please refer to the Event Types topic for more information.
