Sample Code:
Private Const QS_ALLEVENTS As Integer = 1215
Private Const WAIT_OBJECT_0 As Integer = 0
Private Const WAIT_FAILED As Integer = -1
Dim arrHandles(0) As IntPtr
Dim bAddref As Boolean
Select Case MsgWaitForMultipleObjects(1, arrHandles, 1, waitInterval, QS_ALLEVENTS)
Case WAIT_OBJECT_0
retcode = True
Case WAIT_FAILED
Dim errorCode As Integer = System.Runtime.InteropServices.Marshal.GetLastWin32Error
Dim errMsg As String = New System.ComponentModel.Win32Exception(errorCode).Message
Throw New Exception(errMsg)
Case Else
Return False
End Select
Catch ex As Exception
Trace.TraceError("TaskInvoker.Execute - {0}", ex.Message)
Throw
Finally
readyEvent.SafeWaitHandle.DangerousRelease()
End Try
