Hi,

I have made a simple chat program for work, and it is possible to hide the window with the MMB when a teacher or someone of higher rank appears, but I would also like to make the window reappear when you push the MMB again. Unfortunately, the hidden window does not detect the input from the mouse or from the keyboard once hidden... How can I change this?

I haven't tried it but you could use something like this if you have IanM's Matrix1 utilities:

+ Code Snippet

if has focus()=0 and mouseclick()=4 then 'do stuff...

mouseclick()=4 for middle mouse button right?

I found that mouseclick()=4 doesn't work in windowed mode, so I use the user32 dll to call the check.

As to the code you posted, that is exactly what I have (without the focus, what does that do?), and it doesn't show any input when the window is hidden.

Focus = HAS FOCUS()

Returns a result of 1 if the DBPro window has the current focus, or 0 if it doesn't.
"

I just tried the following code:

+ Code Snippet

sync on
sync rate 60

do
	set cursor 0,0
	cls
	print mouseclick()
	if has focus()
		print "HAS FOCUS"
		print mouseclick()
	else
		print "NO FOCUS"
		if mouseclick()=4
			print "MIDDLE-CLICK"
		endif
	endif
	sync
loop

I think using mouseclick() you only ever get a result if you click on the screen...

Maybe if you added your user 32 code? If you get it working could you post the code? I'd love to see how to do this!

When your window does not have focus, you don't get messages from the input devices, otherwise your keypresses would affect every program you have open.

When your window is reduced, then the only messages that matter are close, restore and maximise messages (plus other 'housekeeping' messages) and windows won't send you input messages.

That's why it isn't working - there's nothing you can do to change this, except to write a program to register a hotkey that does the job. That can't currently be done in DBPro.

Actually you can check the input without having focus:

+ Code Snippet

set display mode 800,600,32
set window on
set window size 800,600
hide window
load dll "user32.dll",1

do

pressed = call dll( 1, "GetAsyncKeyState",4 )
if pressed <> 0
    show window
endif

loop

For a list of all key codes (4 is the code for the MMB) look here:

Well, it's pretty easy to make a keylogger with this (hint:although check wether shift is pressed or not

), but you can although do some other nice stuff like a statistics programm, which checks how often you pressed a specific key/button.
And if you know how to get the high and low bytes in DBP (unforunatly I don't) you can easily check if a button has just been pressed, is holding down or is released, and so there's no need of makeing an array to store these values.

I don't have Norton installed, but I'm pretty sure that it won't, because calling the GetAsyncKeyState function isn't something abnormal.
By the way: I think we should stop here, before we're completly off topic.
