Here's my current code:

Try changing:

I'm gonna try it but doesn't getMainForm() just return the cheat window (of which I have not made) and not the main window showing the cheat list?

Edit: It worked! I put getMainForm() in there and it worked perfectly, loaded up a save game in the training day where I only had 2 items (both weren't at full before activating the cheat), they were nicely filled on activating the cheat and then I went chasing after snow to fight that minion that lumina summons and get a new item out of that, then I checked the amount after returning to the field and it was also 99 instead of 1 which means I achieved what I was looking for out of that, now gonna check if I properly disable the timer in my other function.

With this I am one step closer to completely removing the old ASM stuff that was in the table when I downloaded it (and building a decent table for referencing when I want to upgrade my existing custom tables)

huh, whats the logic behind that @TheyCallMeTim13? Some inheritance? or just a guess since you haven't done it that way before Smile

Other languages generally require a proper parent so the resource clean up can know how to handle it. And I tried it on mine, just had a hunch, with the access violation that I seemed to get when I didn't give it a parent at all, It may be some thing unique to windows 7, or maybe the service pack, not really sure if it doesn't do it to every one (I just assumed it did).

Makes sense.
It is marked as optional however

Yeah, like I said it does it me, may be some setting that makes my system more strict on that, but I have not done that on purpose. But I do have QT, PyQt, Code Blocks, Visual Studio, Oracle's IDE, and now Lazarus (plus some odd ball ones for one off embedded languages). So may be one of these has caused this.

Oracle has an IDE? ah, Netbeans is Oracle, though it looks like they've had at least one other lol. I've had all of those installed at one time or another, currently just VS community and Lazarus though Smile

I have to admit this is making me more curious as to way it seems to always happen to me. I might have to do some poking around if I find any thing I will PM you (and/or make a post if I have a fix).

But I have 2 IDEs that embeds Lua for some devices, and this f'in iWrite thing, and some others I can't even remember (had to use them for projects from time to time).

I was hoping you'd get curious Smile

I've always used it with nil (except for rare cases where it made sense to use a specific parent) and haven't had anyone complain, though I doubt most of what I've shared is used a lot I'm sure they've been tried a few times lol

MemoryRecord inherits of the Object class

The timer create function either takes nil, or a type inherited from the "Component" class

Object does not inherit from Component , so when the timer creation tries to access a value in the MemoryRecord's Component memory to specify it's a child of MemoryRecord, it'll access unrelated memory, and likely crash

(I should probably mention in the docs that owners can only be Component class or higher, or just disallow it)

That's about what I expected DB, and yeah it should be mentioned in the docs (and probably disallowed in the code as well if it's trivial) Smile

Though much of the discussion here, past the solution, stems from the fact that Tim will get an access violation from nil as well, which shouldn't happen.

that might have been a very old CE that didn't properly initialize owner, or memory corruption was the cause here, (e.g giving the wrong parent may go fine for a few times until there's too much damage)
but the code path does not do anything if the owner var is nil

Yeah, I got so in the habit of passing the main form as the parent, but it's not doing it to me with 6.7, so kinda hard for me to say. And heck maybe it was just me doing some thing else that seemed unrelated but was my problem all along.

But even when I did get this error, I saw code with nil as the parent all the time.

EDIT:
I think it was like version 5.2 when I got this error the first time.
