Windows Multimedia Timer

[polyplay]

Windows dll "winmm.dll" has set time event that can call a function to be executed periodically based on the timer period. Any idea how it is possible to pass a VI to be executed.

Here is dll's function :

The timeSetEvent function starts a specified timer event. The multimedia timer runs in its own thread. After the event is activated, it calls the specified callback function or sets or pulses the specified event object.

MMRESULT timeSetEvent(

UINT uDelay,

UINT uResolution,

LPTIMECALLBACK lpTimeProc,

DWORD dwUser,

UINT fuEvent

);

Parameters

uDelay

Event delay, in milliseconds. If this value is not in the range of the minimum and maximum event delays supported by the timer, the function returns an error.

uResolution

Resolution of the timer event, in milliseconds. The resolution increases with smaller values; a resolution of 0 indicates periodic events should occur with the greatest possible accuracy. To reduce system overhead, however, you should use the maximum value appropriate for your application.

lpTimeProc

Address of a callback function that is called once upon expiration of a single event or periodically upon expiration of periodic events. If fuEvent specifies the TIME_CALLBACK_EVENT_SET or TIME_CALLBACK_EVENT_PULSE flag, then the lpTimeProc parameter is interpreted as a handle to an event object. The event will be set or pulsed upon completion of a single event or periodically upon completion of periodic events.

dwUser

User-supplied callback data.
