Question : MS Access VBA - Timer To Trigger Event Every 15 minutes

I'm using the following code to auto-refresh a form's contents every 1.5 minutes.

Private Declare Sub sapiSleep Lib "kernel32" _
        Alias "Sleep" _
        (ByVal dwMilliseconds As Long)

Sub sSleep(lngMilliSec As Long)
    If lngMilliSec > 0 Then
        Call sapiSleep(lngMilliSec)
        DoEvents
    End If
End Sub

Public Sub timeRefresh()

Const cTIME = 90000 'in MilliSeconds

Call sSleep(cTIME)
DoEvents

Call cmdCalculate_Click

End Sub

My problem: Even with the DoEvents the code above prevents the user from using their system because the sleep routine basically hogs the processor.

I need to run an event every 1.5 minutes from MS. Access and I need the system's resources to be available to the user whilst the application is waiting.

Answer : MS Access VBA - Timer To Trigger Event Every 15 minutes

Use the form's OnTimer event and not the API stuff.
