Reduce Memory Usage in VFP

Within a timer, this function can be running periodically to reduce memory usage vfp application.
I have already try and work with well.

Function ReduceMemory()

Declare Integer SetProcessWorkingSetSize In kernel32 As SetProcessWorkingSetSize  ;
Integer hProcess , ;
Integer dwMinimumWorkingSetSize , ;
Integer dwMaximumWorkingSetSize
Declare Integer GetCurrentProcess In kernel32 As GetCurrentProcess
nProc = GetCurrentProcess()
bb = SetProcessWorkingSetSize(nProc,-1,-1)

Get Data Temperature Sensor with VFP

This sample VFP code for read data from temperature sensor :

thisform.timer1.Interval = 1000


** SENSOR 01
