Memory Leak with Flash

[ChrisL]

I have a memory leak caused by an object ShockwaveFlash.

The below script will delete the the control and the object and recreate it, if you watch the memory in Task Manager it keeps going up every time you delete and recreate the control.

Any ideas?

Thanks

 

expandcollapse popup

 
Opt("GuiOnEventMode",1)

#include <GUIConstantsEx.au3>
Global $hGui, $flashControl, $SWFObj

_Gui()

While 1
Sleep(250)
WEnd

Func _Gui()

$hGui = GUICreate("ShockwaveFlash.ShockwaveFlash",280,280)
GuiSetState()
GUISetOnEvent($GUI_EVENT_CLOSE,"_Exit")

$flashControl = _CreateSWF(@scriptDir & "\loading9.swf", 40,40, 200,200)

Local $button = GUICtrlCreateButton("Delete and Renew",10,10)
GUICtrlSetOnEvent($button,"_DeleteFlashControlAndCreateANewOne")

EndFunc


Func _DeleteFlashControlAndCreateANewOne()

GUICtrlDelete($flashControl)
ConsoleWrite("$SWFObj is object = " & IsObj($SWFObj) & @CRLF)
$SWFObj = 0
ConsoleWrite("$SWFObj is object = " & IsObj($SWFObj) & " so why don't I get my memory back?" & @CRLF)
Sleep(250)
$flashControl = _CreateSWF(@scriptDir & "\loading9.swf", 40,40, 200,200)

EndFunc

Func _CreateSWF($SWFPath, $SWFL, $SWFT, $SWFW, $SWFH, $SWFBGColor = "#000000")

If NOT FileExists($SWFPath) then Return

$SWFObj = ObjCreate("ShockwaveFlash.ShockwaveFlash")
Local $SWFActiveX = GUICtrlCreateObj($SWFObj, $SWFL, $SWFT, $SWFW, $SWFH)

With $SWFObj
.Movie = $SWFPath
.ScaleMode = 1
.bgcolor = $SWFBGColor
.Loop = True
.allowScriptAccess = "Always"
.Quality = 1
.Playing = 1
.Menu = 1
EndWith

Return $SWFActiveX

EndFunc

Func _Exit()
Exit
EndFunc

I've seen this issue raised before, I don't think there was a solution if I recall.

Let me ask, id this a real world problem for you or are you just showcasing that you think you found a bug?

Can you demonstrate the real world issue if it is that?

[ChrisL]

It's a real problem in a huge script, the one I posted above is a simplified script to show the problem

[JohnOne]

Could you not solve the issue by not constantly deleting the object and making a new one?

Or perhaps add a long sleep duration between deleting and creating the object, I had the same issue with _IENavigate (irrelevant I know) where _IEQuit didn't work everytime and the process would start hugging the memory and causing a leak.

[ChrisL]

I do delete the object and recreate and that is where the memory leak happens, even if there is a long delay there is always memory taken up when you create a flash object delete it and create another several times.

could you simply use the adobe flash projector?

[ChrisL]

Ahh I miss-read that!

I have now done this and it does solve the issue, I shouldn't really have to do this, I would expect the memory to be released.

[JohnOne]

Agreed, but if I recall correctly it's not about to be fixed any time soon.
