Hi

I've posted this under the heading 'Splitting Strings' but when it caused an access violation, that's different so I'm opening this new topic. OS is Vista Home Basic on a Celeron D with 512Mb RAM.

Script running at the time was as below - compiles OK, the only thing changed to cause the violation was the addition of the global object 'Noel'

Code: WME Script

1. function SetState()
2. {
3.   var BtnUp = this.GetControl("up");
4.   var BtnDown = this.GetControl("down");
5.   var BtnLoad = this.GetControl("load");
6.  
7.   var Thumbnail = this.GetControl("thumbnail");
8.  
9.   BtnUp.Disabled = (ScrollOffset <= 0);
10.   BtnDown.Disabled = (ScrollOffset+NumSlotButtons > LastUsedSlot);
11.   BtnLoad.Disabled = (SelectedSlot < 0);
12.    
13.  
14.   for(var i=0; i<NumSlotButtons; i=i+1)
15.   {
16.     var SaveSlot = LastUsedSlot - ScrollOffset - i;
17.     //var SlotButton = this.GetControl(i+1);
18. var SlotButton = this.GetControl(i);
19.     SlotButton.Pressed = (SaveSlot==(LastUsedSlot-SelectedSlot));
20.     SlotButton.Text = SaveSlot;
21.     if(SaveSlot >= 0 && Game.IsSaveSlotUsed(SaveSlot))

37.             SlotButton.Text = StringSplit.Substr(16, l-16);
38.             }

[metamorphium]

the violation is imo caused by using unitialized object String. Really include the keyword new and let us know if it crashes.

You were right, adding the 'new' seemed to stop the violation. Odd that removing it made no difference at first. Ah well. And now, a reboot later, my Game.Msg's have suddenly started working.

Nervous? Moi? Nah. I love unpredictability    But, with Game.Msg spitting stuff out now, time to see what was causing the string glitch in the first place. 

This enquiry can be closed.

Thanks for your help.
