_ReduceMemory UDF

[FastHelper]

this is the UDF

Func _ReduceMemory($i_PID = -1)
    
    If $i_PID <> -1 Then
        Local $ai_Handle = DllCall("kernel32.dll", 'int', 'OpenProcess', 'int', 0x1f0fff, 'int', False, 'int', $i_PID)
        Local $ai_Return = DllCall("psapi.dll", 'int', 'EmptyWorkingSet', 'long', $ai_Handle[0])
        DllCall('kernel32.dll', 'int', 'CloseHandle', 'int', $ai_Handle[0])
    Else
        Local $ai_Return = DllCall("psapi.dll", 'int', 'EmptyWorkingSet', 'long', -1)
    EndIf
    
    Return $ai_Return[0]
EndFunc;==> _ReduceMemory()

i am newbie please tell me how to use it.

Example of my Code:

opt("WinTitleMatchMode", 2)
Func _MinimizeToTray($fStartup = False)
    $fUpdateMeminfo = False
    If Not $fStartup Then GUISetState(@SW_HIDE)
    TraySetState()
    AdlibDisable()
EndFunc
If WinExists("AutoIt Forums") Then
    WinSetState("AutoIt Forums", "", @SW_SHOW)
     ToolTip("You Are Visiting Autoit Forums Right Noe", 400, 300, "Message", 2, 2)
EndIf
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main", "Window Title", "REG_SZ", "I Love AutoIt")

anyone will tell me about it?

If you want to reduce the memory usage of your current AutoIt process then

_ReduceMemory(@AutoItPid)


Func _ReduceMemory($i_PID = -1)
    
    If $i_PID <> -1 Then
        Local $ai_Handle = DllCall("kernel32.dll", 'int', 'OpenProcess', 'int', 0x1f0fff, 'int', False, 'int', $i_PID)
        Local $ai_Return = DllCall("psapi.dll", 'int', 'EmptyWorkingSet', 'long', $ai_Handle[0])
        DllCall('kernel32.dll', 'int', 'CloseHandle', 'int', $ai_Handle[0])
    Else
        Local $ai_Return = DllCall("psapi.dll", 'int', 'EmptyWorkingSet', 'long', -1)
    EndIf
    
    Return $ai_Return[0]
EndFunc;==> _ReduceMemory()

where to add it in my script and do i need to call this function again and again?

[SmOke_N]

The function empties the working set of the application, as the application continues to go on, the working set builds up again. So the answer is yes, to empty the working set, you'll have to call when ever you want this action to happen.

The script you provided would run for about 2 milliseconds then exit it has no need for this function at all.

If you don't know where to use it then I don't think you need to use it at all.

Why do you think you need to use it?

The script i provided was just a example script (not origional part of program code). i want to use it in my script because i think it is useful code. and this is the only reason why i want to use it. i want to learn about it. it will help to reduce memory size in all scripts which will be good for pc.

Well then we can't really tell you where to put it.

If you were using a lot of memory at some point in your script then doing very little you might want to call the function.

From what I've seen it pretty much dumps what it can to virtual memory reduces the physical ram usage but increases the virtual ram usage. Not so good because virtual memory runs slower.

Windows is quite capable of doing this when it needs to anyway
