Does anyone remember/know what API commands to use to check for pressing an up or down arrow?
I'd rather not use the PB keyboard function because that requires an up-to-date DirectX installed and a lot of people who test my programs do not have that and of course it crashes.
/me falls out of the chair asleep. (IRC talk)
Thanks to anyone who remembers:)

Code: Select all
GetAsyncKeyState_(#VK_UP) ; Clear up key buffer.
GetAsyncKeyState_(#VK_DOWN) ; Clear down key buffer.
;
; And to check their state during runtime:
If GetAsyncKeyState_(#VK_UP)=-32767 ; Up arrow pressed.
If GetAsyncKeyState_(#VK_DOWN)=-32767 ; Down arrow pressed.

I tested it and it is the right way to do it now ... good and useful.

Using the API is not a "wrong" way, you know.

A. I don't know where to put it (no example).
B. I don't know the syntax to check it.
I need to generate an up and down arrow event in a ListIconGadget so that I can go to some code. Where do I put that above code, how do I check it??

Thanks PB, but I get "Constant not found" for those two.

Sorry, they're meant to be #VK_UP and #VK_DOWN (I typed them from memory and
while half-asleep). I've fixed my example above to reflect this. BTW, all
these constants are found in the Win32API.doc file, if you have it. If not,
it's here (143k):
