 Posted: Fri Nov 19, 2004 6:50 pm Post subject: How to keep down memory usage |
 |
|
After playing a bit with some windows on my screen because I had to wait for various tasks, I found out a way to really optimize your computer when using lots of windows. If you open for example Internet Explorer, it uses about 20 MB of memory. When you minimize the window, it will reduce to 7 MB. So far no news. But, when you restore the window's state, it stays on that 7 MB until you've visit 4 of 5 new websites. And the same counts for various of other programs. This means that if you are able to write a program which minimizes all windows which are not visible on the screen, you can gain a enormous amount of memory. I just tried to create a program which minimizes windows which are not active, but then you can only use on window at a time. Does anybody know a trick to get a list of all visible windows, so I can filter out all others and to test if my theory works?
Thanks...

The simplest method I can think of:
| Code: |
list create,1
list winlist,1,I
rem Loop thru list using API call 'IsWindowVisible(HWND)'
list close,1
|
Maybe this will help. I don't use VDS 5 but this does work in 'C'.

| MSDN Library wrote: | Syntax
BOOL IsWindowVisible(HWND hWnd);
Parameters
hWnd
[in] Handle to the window to test.
Return Value
If the specified window, its parent window, its parent's parent window, and so forth, have the WS_VISIBLE style, the return value is nonzero. Otherwise, the return value is zero.
Because the return value specifies whether the window has the WS_VISIBLE style, it may be nonzero even if the window is totally obscured by other windows. |
I'm afraid it won't work this way...  Does anybody maybe know another API code to see which windows are visible on the screen, and which not?
Garrett: the code you linked to does only give a list of all windows which are in the taskbar, not the ones which are visible, but thank you just the same...

Ya might try @winpos([window], S) in your winlist loop.
It returns the window status (1 = normal; 2 = iconized; 3 = maximized).
Cheers, Mac

Sure, the whole code, but if you walk through the code, you'll see that
one can easily get what they need out of this. As many have noted, you
can use the @winpos([window], S) to check the status of each and every
window.

Garrett and Mac, sorry if I was unclear, but I want to get a list of all windows which aren't (partially) visible on screen. The API function Bill mentioned does work, but unfortunately not with all programs.
What I am trying to do with this list, is to minimize all programs which the user can't see while he is working. This should reduce the memory Windows gives these programs, so that the others have more to run with.

Skit, the only way I can think of to do that is to scan the screen
xy in 10-15 pixel increments and use @winatpoint() to see what
is actually visible.
Actually ya could scan screen x in much larger increments
because windows are seldom less than 100 pixels wide.

BTW, you prolly need to keep the x scan small too because
there may only be 10-15 pixels of an overlapped window visible.
Cheers, Mac

This is the code I came up with. It gets about all window handles on the screen, but I don't know how to get the parent of these handles. I tried it with @window(<handle>,handle), but that doesn't work on programs like IE and Notepad... 
| Code: | list create,1,sorted
%x = 1
repeat
%y = 1
repeat
%%handle = @winatpoint(%x,%y)
%%owner = @window(%%handle,owner)
if @not(@null(%%owner))
%%title = @wintext(%%owner)
else
%%title =
end
list add,1,Handle: %%handle@tab()Owner: %%owner@tab()Titletext: %%title
%y = @sum(%y,10)
until @greater(%y,@sysinfo(screenheight))
%x = @sum(%x,10)
until @greater(%x,@sysinfo(screenwidth))
info Done...@cr()@cr()@text(1)
list close,1 |

My spy tool ( http://www.vdsworld.com/forum/viewtopic.php?t=450 )
uses:
@window(@winatpoint(%x,%y),OWNER)
but it doesn't show a parent on everything either.
Ya can prolly assume those that show no parent aren't
child windows anyway...
