Simple vista thumbnail example

Can you run this real quick and post your output?

I get exactly the same results.

Well, then I have no idea why things look different on our systems... grr.

Still tinkering on it... latest version added below ...

@wraithdu:

Hmmm, still trying to figure out the borders. In your example above you use

$a_WinGetPosEx[2] -= (2*_WinAPI_GetSystemMetrics(33)) ; width of vertical frames
If BitAND(_WinAPI_GetWindowLong($hwnd_calc, $GWL_STYLE), $WS_CAPTION) Then
    ; height of horizontal frames + height of caption
    $a_WinGetPosEx[3] -= ((2*_WinAPI_GetSystemMetrics(32)) + _WinAPI_GetSystemMetrics(4))
Else
    $a_WinGetPosEx[3] -= (2*_WinAPI_GetSystemMetrics(32))
Endif

which results in a little blur on my computer, but if I exchange 32 with 7 and 33 with 8 it looks good!

; subtract the frame sizes
$a_WinGetPosEx[2] -= (2*_WinAPI_GetSystemMetrics(8)) ; width of vertical frames
If BitAND(_WinAPI_GetWindowLong($hwnd_calc, $GWL_STYLE), $WS_CAPTION) Then
    ; height of horizontal frames + height of caption
    $a_WinGetPosEx[3] -= ((2*_WinAPI_GetSystemMetrics(7)) + _WinAPI_GetSystemMetrics(4))
Else
    $a_WinGetPosEx[3] -= (2*_WinAPI_GetSystemMetrics(7))
Endif

Strange, maybe has something to do with the windows theme?

My results with calc in scientific mode:

WinGetClientSize: 407 264
_WinGetPosEx: 117 162 423 322
_WinAPI_Ex_GetWindowInfo - Window: 117 162 540 484

_WinAPI_Ex_GetWindowInfo - Client-Width: 407
_WinAPI_Ex_GetWindowInfo - Client-Heigth: 264
_WinAPI_Ex_GetWindowInfo - Borders: 3 3

This is on my Win7 x64 desktop. I'll try to test my laptop later, tomorrow at the worst.

Window - Heigth 312 322

Client - Heigth 264 264

Client - Width 407 407

Now that's odd ... the windows-borders seem to be 5px per side wider on your computer then on mine. That's also why _WinAPI_GetSystemMetrics(7) = 3px works for me and _WinAPI_GetSystemMetrics(32) = 8px works for you!

http://msdn.microsoft.com/en-us/library/ms724385%28VS.85%29.aspx

_WinAPI_GetSystemMetrics(7)

"The thickness of the frame around the perimeter of a window that has a caption but is not sizable, in pixels."

_WinAPI_GetSystemMetrics(32)

"The thickness of the sizing border around the perimeter of a window that can be resized, in pixels."

Okay, seems like the calc window does have a slightly different style on your computer... we have to add a switch to the calc method depending on the style responsible for this... which one is it :huggles: ? AU3Info returns following styles for my calc.exe

Style: 0x14CA0000

ExStyle: 0x00000100

Here's my run on my laptop:

_WinAPI_Ex_GetWindowInfo - Window-Width: 423
_WinAPI_Ex_GetWindowInfo - Window-Heigth: 322

_WinAPI_Ex_GetWindowInfo - Client-Width: 407

_WinAPI_Ex_GetWindowInfo - Borders: 3 3

Hmm, do you run any window managers or skins or custom scripts that modify windows (like NVidia's NView or something)?

Your new method produces the same results. I have to switch to the GetSystemMetrics method, then it works perfectly for 'Client area only'. Full window mode works fine without adjustments.

wraithdu · January 29, 2010

AutoIt Window Info shows the same style and exstyle for calc on my laptop as what you posted.

Are you using any windows themes or accessibility tools?

KaFu · January 29, 2010

Are you using any windows themes or accessibility tools?

No. Maybe it's the AERO settings? I've set them to custom and enabled all checkboxes.

Above code contained an error, DwmQueryThumbnailSourceSize was only called on creation but not on the sub-sequent adlib calls . Additionally I deleted all GetSystemMetrics() calls, let's see if windows can handle it by itself :huggles: ...works "fine" for me, pls test.

Yeah, that one works both full and client only Nice job.

BTW, I think you'll want to use _GUICtrlListView_GetItemChecked instead of Selected for your listview.

Now, where are you changing the Aero settings with a bunch of checkmarks? I'm having a hard time finding that menu.

great to hear, already tinkering on a better GUI

Will do!

Yeah, Win7 system settings are hell

Oh, that one. Yeah, that shouldn't make a difference.

Hu, hadn't seen that bug-report. As I'm utilizing this function quiet often this comes in really handy, thanks for the heads up

!

But what's bothering me more... it seems that the OS stops updating / redrawing minimized windows. Monitor a window which is constantly redrawing, e.g. a firefox window, and then minimize it to taskbar... you'll see that the thumbnail will stop updating too... aaarrrghhh, windows!

Edit:

The only way to prevent the source window from stopping to redraw I see atm is to add something like this

ElseIf BitAND($i_hwnd_Source_State, 16) then WinSetState($hwnd_Source,"",@SW_SHOWNOACTIVATE)

Not really nice.

BUT what I observed is, when you add that code, then press the "Show Desktop" button in the lower right (WIN-D doesn't work), the window is still updated. There has to be something like a mixed mode somewhere, will look into what windows does when the user presses that button :huggles: .

Not even the Windows superbar thumbnails update while the window is minimized, so I wouldn't worry too much if you can't find a solution.

One more thing, while your _WindowDrag() function works fine, you don't really need it. You just have to give the thumbnail GUI the $WS_EX_CONTROLPARENT extended style:

$hwnd_Thumbnail = GUICreate("Vista Thumbnail", 100, 100, 100, 100, $WS_POPUP, BitOR($WS_EX_TOOLWINDOW, $WS_EX_TOPMOST, $WS_EX_CONTROLPARENT))

Is there a way to use this dll to get the displayed content of a minimized window?

KaFu · August 30, 2012

No, for performance reasons the thumbnails are not refreshed using this public API for minimized windows. Though there has to be some undocumented way, as e.g. a thumbnail of the Windows Media Player is updated even minimized...
