ScreenCapture problem

[joelb]

Hi everyone ,

I am a newb with Autoit , yet we consider using it for a project in our company so I could really use help.

Here's my problem : I have made a tool whose job is to run a couple of processes , take a snapshot of the window with a specific process and shut down.

I wrote the script , made an exe (with auto2exe tool) and ran it on my machine and it works alright .

However , running my exe on a friend's machine yields bad result - the snapshot taken is not of the wanted window but of everything 'behind' the window (I get a screenshot of the portion of the desktop that is behind the window that I want).

Both of our machines run windows7 so I don't know what's the difference other than obviously he does not have autoit installed (does it matter?)

I suspect that maybe the #include <ScreenCapture.au3> line got messed up somehow otherwise I'm completely lost ...

My code :

#include <ScreenCapture.au3>

FileInstall("C:UsersJuelDesktoptoolv3.0releaseexecute.exe", @WorkingDir & "execute2.exe")

FileInstall("C:UsersJuelDesktoptoolv3.0releasetool.exe" , @WorkingDir & "tool2.exe")

;takes process id and returns window handle

Func _GetHwndFromPID($PID)

$hWnd = 0

$winlist = WinList()

Do

For $i = 1 To $winlist[0][0]

If $winlist[$i][0] <> "" Then

$iPID2 = WinGetProcess($winlist[$i][1])

If $iPID2 = $PID Then

$hWnd = $winlist[$i][1]

ExitLoop

EndIf

EndIf

Next

Until $hWnd <> 0

Return $hWnd

EndFunc

Run("tool2.exe")

ProcessWait("execute2.exe")

$pid=ProcessExists("execute2.exe")

Sleep(8000)

$handle=_GetHwndFromPID($pid)

_ScreenCapture_CaptureWnd(@DesktopDir & "offer_Image.jpg", $handle)

ProcessClose($pid)

joelb,

Welcome to the AutoIt forum.

Just a guess, but does your friend have Aero enabled and you not?

P.S. Please use more descriptive titles in future - "Newb really needs help" is not very informative.

Hi Melba,

Could you please explain the problem with aero or please tell me what to type into the search to find out what are you talking about.

I am always FEARFUL of posting in these forums, just in case someone flames me for putting in a dumb question.

I have found this thread because I too am having problems with my Window (screen) capture program as a result of the latest AutoIt version (v3.3.8.1), it has changed the way _ScreenCapture_CaptureWnd works.

Whether I have Aero on or off does not seem to matter.

I am passing the window control ID from a different program (that part has not changed) but it looks like _ScreenCapture_CaptureWnd does not like the old controlID. So now, I get the entire desktop screen instead of just the window.

Any help would be greatly appreciated.

joelb, did you get any further?

The handle for a window is different every time the program is run, what are you using to get the handle from the window you're trying to capture?

Hi BewManNH,

Thanks for responding.

I am using an object oriented language called OpenROAD (by Ingres Corp)...

Internally, each frame that is instantiated has its own "widgetid" and in the past this worked as the windows control id.

eg: hwnd = curframe.widgetid;

Please do not be - as you can see from the Forum Rules we do not tolerate flaming here. Everyone is welcome as long as they respect those rules, regardless of their experience level - after all everyone of us started at the beginning at one point in our coding lives.

And if it does happen because someone slept badly the night before - just report it and the Moderating team will deal with it.

Hi Melb23,

Why would Aero be a problem?

[Melba23]

Andy007,

Using Aero can give problems with some screen reading functions (particularly the Pixel* ones), so I thought it worthwhile asking.
