Visual Basic 2008 KeyDown Delay? [RESOLVED]

Hey everybody, I've been doing Visual Basic game development for about 7 months now. I've never actually tried making an RPG style game before, but now I am attempting to accomplish it. I've always used the KeyDown event for checking if a key is pressed to move your character. However, when you do hold a key down, it responds as if in a text program... It sends the key once, waits, then continues going. I would like to remove this delay within the program, but nowhere else. I would also like to remove it without having to change the user's settings. Any help will be appreciated. Thanks!

What you should do is have to subs that handle KeyDown and KeyUp events respectively, and some sort of structure/class for holding key states, then have those 2 subs update the keystates, and have a timer-activated sub that uses them. At least that's how I do it.
Also, check out KeyPress events. I'm not sure, but they seem more likely to have key repeat than KeyDown events.

That's pretty much what I do. But I'm talking about the delay when you hold the key down. I might just not understand exactly what you said. And I've attempted to work with KeyPress but I couldn't find a working solution to execute the same code that my KeyDown event does.

well if you control the key state something like this:
Code: Select all
private sub onDown(...) handles KeyDown
state.<key> = true
end sub
private sub onUp(...) handles KeyUp
state.<key> = false
end sub
then it should reliably tell you when a certain key is currently being pressed. You can take advantage of this in a sub that handles a Timer.Tick event:
Code: Select all
private withevents t as Timer
sub New()
t = new Timer(...)
t.start()
end sub
private sub frameLogic() handles t.Tick
' do stuff
end sub

I haven't attempted it yet, but will it remove the delay and tell me if the key is being pressed or held down?

Hm... When I executed the code, it produced the same delay..

it shouldn't produce a delay if you actually have some sort of way of storing the state and you use other subs (read: not onDown and onUp) to check the key states for different things. If you keep using onDown and onUp for logic, there will be a delay.

Ah, I modified the code a little bit and it worked! Thanks :D
