CeRunAppAtTime

8/28/2008

This function prompts the system to start running a specified application at a specified time.

Syntax


BOOL CeRunAppAtTime(
  TCHAR* pwszAppName, 
  SYSTEMTIME* lpTime 
);

Parameters

pwszAppName: [in] Pointer to a null-terminated string that specifies the name of the application to be run.

lpTime

[in] Long pointer to a SYSTEMTIME structure that specifies the local time when the given application is to be run.

If this parameter is NULL, the existing run request is deleted and no new request is entered. The deleted run request must have been initiated by a call to CeRunAppAtTime.

Return Value

TRUE indicates success. FALSE indicates failure.

Remarks

Calling the CeRunAppAtTime function replaces any previous run request for the specified application.

The system passes the APP_RUN_AT_TIME string to the application as the command line. If an instance of the application is already running, the new instance must send a private message to the existing instance and then shut down.

Use CeRunAppAtTime sparingly because automatically starting an application can confuse the user and cause low-memory conditions on a machine with restricted memory. Ideally, the application should be small and non-intrusive.

If the specified time falls within the platform-dependent period defined by the accuracy of the real-time clock (RTC), the notification is scheduled immediately. The accuracy can be retrieved using IOCTL_KLIB_GETALARMRESOLUTION and ranges from 1 to 60 seconds. If the system does not implement IOCTL_KLIB_GETALARMRESOLUTION, the default RTC accuracy of 10 seconds is assumed.

Requirements

Header	notify.h
Library	coredll.lib
Windows Embedded CE	Windows CE 1.0 and later
Windows Mobile	Windows Mobile Version 5.0 and later

Using CeRunAppAtTime to Signal Events

Joel Ivory Johnson | Edit | Show History

CeRunAppAtTime can also be used to signal named objects. Within notify.h the string constant NAMED_EVENT_PREFIX_TEXT is defined (along with the numeric constant NAMED_EVENT_PREFIX_LEN, which defines its length). Build a string that is composed the name of the named object to be signaled appended to this constant and pass the result in the parameter pwszAppName and CeRunAppAtTime will signal events instead of running an application.
