@msdn=http://search.microsoft.com/search/results.aspx?qu=$$$ @pinvoke=http://pinvoke.net/$$$.htm Summary: This function prompts the system to start running a specified application at a specified time. !!!!C# Signature: [DllImport("coredll.dll", EntryPoint="CeRunAppAtTime", SetLastError=true)] private static extern bool CeRunAppAtTime(string pwszAppName, byte[] lpTime); !!!!VB Signature: Public Declare Function CeRunAppAtTime Lib "coredll" _ (ByVal AppName As String, ByRef ExecTime As SYSTEMTIME) As Boolean !!!!User-Defined Types (VB): Public Structure SYSTEMTIME Dim wYear As Short Dim wMonth As Short Dim wDayOfWeek As Short Dim wDay As Short Dim wHour As Short Dim wMinute As Short Dim wSecond As Short Dim wMilliseconds As Short End Structure !!!!Alternative Managed API: CeSetUserNotificationEx !!!!Notes: In VB, function will return "true" if successful when adding app to run. However, it returns a "false" when cancelling the app '''even though the event is successfully cancelled'''. I'm guessing this is due to the systemtime structure being passed by reference and in this case references nothing. See sample code below. (VB .NET CF) !!!!Tips & Tricks: While this wakes the device, the screen may remain powered off. Combine with SetSystemPowerState truly wake up everything. Also, if the app is making a call to wake itself back up, you can get the full path and appname with system.reflection.assembly. See code below for example. !!!!VB Sample Code: Dim FullAppName As String = System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase Dim AppPathOnly As String = System.IO.Path.GetDirectoryName(FullAppName) Dim NewDate As Date Dim wakeuptime As SYSTEMTIME Private Sub scheduleapp NewDate = Now 'take the current time and date and add some hours, minutes, and seconds NewDate = DateAdd(DateInterval.Hour, 5, NewDate) NewDate = DateAdd(DateInterval.Minute, 10, NewDate) NewDate = DateAdd(DateInterval.Second, 30, NewDate) 'populate systemtime structure with our new date With wakeuptime .wDay = NewDate.Day .wDayOfWeek = NewDate.DayOfWeek .wHour = NewDate.Hour .wMilliseconds = NewDate.Millisecond .wMinute = NewDate.Minute .wMonth = NewDate.Month .wSecond = NewDate.Second .wYear = NewDate.Year End With If CeRunAppAtTime(FullAppName, WakeUpTime) Then MessageBox.Show("App successfully scheduled to run") Else MessageBox.Show("Call to CeRunAppAtTime failed") End If End Sub Private Sub cancelschedule 'Make a call to cancel the scheduled app Dim cancelapp as boolean = CeRunAppAtTime(FullAppName, Nothing) End Sub Documentation: CeRunAppAtTime@msdn on MSDN
