Cant get exit loop with button to work

[Champak 5]

For $I = 0 to 10;Could be anywhere from 1 to 5000

     ;A bunch of code

     $msg = GUIGetMsg()
     Select
    Case $msg = $LOAD_SCREEN
    ExitLoop
     EndSelect

next

for $I = 5 to 10
     $msg = GUIGetMsg()
     if $msg = $LOAD_SCREEN Then ExitLoop
next

These are what I've tried, Thanks

I'm trying to figure out why you are not using a while loop instead. You say the loop could be anywhere between 1 and 5000 iterations. This loop will most likely time out before you get chance to interact with your GUI, so unless you are superman, nothing is likely to happen at that speed.

I also don't know what ' ; A bunch of code ' is doing in that first loop.

Right.  Or even a Do loop.

Do
    $msg = GUIGetMsg()
   Select
    Case $msg = $LOAD_SCREEN
      SomeFunc()
   EndSelect
Until $msg = $GUI_EVENT_CLOSE

 @MilesAhead, I guess I could go that route. I didn't know the For loop is the only one apparently that I cant interrupt with a gui button press. I guess I'll put an Or statement on the Until so it can exit upon the count being reached or the button being pressed. thanks.

You can't interrupt it because it's over and out of the loop in a blink of an eye

Why not use eventmode ?

#include <GUIConstantsEx.au3>
Opt("GuiOnEventMode", 1)
Global $stop = 0

GUICreate("My GUI") 
$label = GUICtrlCreateLabel("", 10, 30, 50, 20)
$btn = GUICtrlCreateButton("stop", 10, 50, 50, 20)
GUICtrlSetOnEvent(-1, "_stop")
GUISetState()  

For $i = 1 to 1000
  If $stop Then Exitloop
  GuiCtrlSetData($label, $i)
  Sleep(300)
Next
Msgbox(0,"", "stopped")

Func _stop()
  $stop = 1
EndFunc
