windows.setWindowPos (windows.getMAXHWND()) 0 0 500 500 true

there is an easier way:

WM_SYSCOMMAND = 0x0112
SC_MAXIMIZE = 0xF030
windows.sendmessage (windows.getmaxhwnd()) WM_SYSCOMMAND SC_MAXIMIZE 0

Yeah, yeah my second monitor burned down a week ago. Looking for a replacement for some time with increasing of working space. And about autohide taskbar in windows i know, but this is boring.

I’m sure)

if you are too bored have a fun:

make max window always on top

get a size of screen

and set size of max window as a screen size

Yeah, now Max is ontop :buttrock:
How to maximize them for all screen?

yes… it’s almost identical to what i showed http://forums.cgsociety.org/showpost.php?p=7177985&postcount=5

now is a full-screen… you have to add size and remove SWP_NOSIZE flag with using the same function.
screen size is:

SystemInformation.VirtualScreen.Width   
SystemInformation.VirtualScreen.Height

that’s it

ah… i forgot… you have also to remove a border. but there is an example i’ve posted here. it was about how to do it.

here is the right answer: http://stackoverflow.com/questions/2398746/removing-window-border

Im on the right way?
If i understood correctly now i must delete borders and then maximize window?

I think i need this?

  			f = ::User32.GetWindowLong hwnd GWL_STYLE
  			f = bit.xor f (WS_BORDER + WS_DLGFRAME + WS_THICKFRAME)

Not sure how to write it correctly
