Holding variable state between hotkey occurences Topic is solved

[Dranh]

I have a question surrounding how to make a variable initialize once and hold its state between invokes\occurrences of a hotkey being triggered. In my example below i have declared 'vMyVar' equal to A_TickCount and I understand this happens everytime F4 is invoked given this approach. Is there a way to have this occur only once and the variable hold its state between invokes of F4? Any pointers to examples/concepts i've been unable to find for myself would be much appreciated.

Code: Select all

F4::
vMyVar := A_TickCount
KeyWait, F4, D;
/* do stuff and calculations with vMyVar */
MsgBox Value of %vMyVar%

Not sure what you goal is, but here's one way:

Code: Select all

#SingleInstance, Force

vMyVar := 0 ; Initialize variable, starting with value of 0

F4:: ; F4 Hotkey
	; If "vMyVar" is 0, get A_TickCount.
	; If not 0, it must already have A_TickCount from previous execution. Show existing value instead of getting new value.
	vMyVar := (vMyVar ? vMyVar : A_TickCount)
	
	; Display value in MessageBox
	MsgBox, % vMyVar
return
