Hiya guys. Currently there is no native Blitz 3D/2D function to get the status of the caps lock key (On or off). Does anyone have any userlibs or similar ways of getting access to this?

You could try setkeyboardstate and getkeyboardstate in User32. No idea if they will work in blitz though I have not tried them, but it would be nice if they did. I expect there will be compatibility issues though.

See if this works. It shows CAPS Lock, Scroll Lock, NumLock, and Insert status:

; keyboard State

; userlibs
; ***********************************************
; .lib "user32.dll"
; GetKeyboardState%(state*):"GetKeyboardState"
; ***********************************************

Const VK_CAPITAL = $14
Const VK_NUMLOCK = $90
Const VK_SCROLL = $91
Const VK_INSERT = $2d

kstate=CreateBank(256)

Graphics 400,300,0,2
SetFont LoadFont ("courier",20)

Repeat
	GetKeyboardState(kstate)
	Cls
	Text 10,10,"Caps       = "+PeekByte(kstate,VK_CAPITAL)
	Text 10,30,"Numlock    = "+PeekByte(kstate,VK_NUMLOCK)
	Text 10,50,"Scrolllock = "+PeekByte(kstate,VK_SCROLL)
	Text 10,70,"Insert     = "+PeekByte(kstate,VK_INSERT)
	Flip
	Delay 5
Until KeyHit(1)

End
