I've been having more and more crash on the IDE with invalid acces memeory for
basic PB commands, I don't understnd where is the problem coming from.

the last 3 I had (within an hour) were on these commands :
- EndProcedure
- SetGadgetState(#ListIconDL, n) : Delay(150)
- If OpenWindow(#Window_Validity, DesktopWidth(0)*nb_bureau+DesktopWidth(0)*0.02, DesktopHeight(0)*0.15, ImageWidth(#Img_Valid), ImageHeight(#Img_Valid), "Validity", #PB_Window_Tool|#PB_Window_BorderLess|#PB_Window_Invisible)

Do I have to wipe PB and make a clean install again?
Can a lot of lib generate this kind of problems?

Also lately I've been having a few "not initialised" bugs generaly all with the same procedure :

Code: Select all

Procedure SetImageWin(*ipara.metre)
	nb_bureau = ExamineDesktops() - 1
	CatchImage(#Img_Valid, ?ValidID) : ValID = ImageID(#Img_Valid)
	CatchImage(#Img_Invalid, ?InvalidID) : InvalID = ImageID(#Img_Invalid)
	If OpenWindow(#Window_Validity, DesktopWidth(0)*nb_bureau+DesktopWidth(0)*0.02, DesktopHeight(0)*0.15, ImageWidth(#Img_Valid), ImageHeight(#Img_Valid), "Validity", #PB_Window_Tool|#PB_Window_BorderLess|#PB_Window_Invisible)
		If CountGadgetItems(#ListIconDL) = *ipara\index + 1

			If *ipara.metre\ValidID = 1 : SetImage(WindowID(#Window_Validity), ValID)
			ElseIf *ipara.metre\ValidID = 0 : SetImage(WindowID(#Window_Validity), InvalID)
			EndIf
			
			HideWindow(#Window_Validity, 0) : StickyWindow(#Window_Validity, 1)
			Delay(750)
			CloseWindow(#Window_Validity)
		EndIf
	EndIf
	ClearStructure(*ipara, metre)
	FreeMemory(*ipara)
EndProcedure

Any help would be greatly apreciated

Try to enable the purifier to see if you don't have a memory buffer overflow

How do I see if I have a memory overflow with the purifier? (Never used it and don't see anything more happening)

An official blog post about the Purifier tool... http://www.purebasic.fr/blog/?p=237

(I thought there was another longer post about investigating IMA errors, either on that site or here, but I can't find it...)

Is it normal to have only this showing when I tested this code from the PB blog with
the purifier checked?
I don't see anything showing an error

Did you enabled the purifier in the 'compiler options' second tabs 'Execute/Run' ? Debugger has to be ON as well. Here it does raise an error.

Yeah, wasn't check in there, strange.
Anyway, now it works, thanks

Gonna check my app like that I'll see if there is a problem.
