GUICtrlCreatePic strange behaviour

Recommended Posts

Zoldex

I'm trying to displaya picture on a gui but it doesn't work if I make some GDI+ operations just before creating the gui:

#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
#Include <ScreenCapture.au3>
#Include <Misc.au3>
#include <StaticConstants.au3>

Local $GUIimg_title,$GUIwidth,$GUIheight,$GUILeft,$GUITop

Local $filename = FileOpenDialog("Select image", @ScriptDir, "Image (*.jpg;*.bmp)", 3)

_GDIPlus_Startup()

Local $imagefromfile = _GDIPlus_ImageLoadFromFile($filename) ;Create an image object based on a file
Local $GUIwidth = _GDIPlus_ImageGetWidth($imagefromfile)
Local $GUIheight = _GDIPlus_ImageGetHeight($imagefromfile)


; Display image
$hBitmap_GUI = GUICreate("", $GUIwidth, $GUIheight)
$hPic = GUICtrlCreatePic($filename, 0, 0)

GUISetState()
_GDIPlus_Shutdown()


While 1

Switch GUIGetMsg()
Case $GUI_EVENT_CLOSE;, $hCancel_Button
Exit
;~
EndSwitch

WEnd

Instead it works if I remove GDI+ ... Can't understand why!

#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
#Include <ScreenCapture.au3>
#Include <Misc.au3>
#include <StaticConstants.au3>
Local $GUIimg_title,$GUIwidth,$GUIheight,$GUILeft,$GUITop

Local $filename = FileOpenDialog("Select image", @ScriptDir, "Image (*.jpg;*.bmp)", 3)

;~ _GDIPlus_Startup()

;~ Local $imagefromfile = _GDIPlus_ImageLoadFromFile($filename) ;Create an image object based on a file
;~ Local $GUIwidth = _GDIPlus_ImageGetWidth($imagefromfile)
;~ Local $GUIheight = _GDIPlus_ImageGetHeight($imagefromfile)
;~ _GDIPlus_Shutdown()


; Display image
;$hBitmap_GUI = GUICreate("", $GUIwidth, $GUIheight)
$hBitmap_GUI = GUICreate("", 800, 800); <---- had to use fixed size...
$hPic = GUICtrlCreatePic($filename, 1, 1)

GUISetState()


While 1

Switch GUIGetMsg()
Case $GUI_EVENT_CLOSE;, $hCancel_Button
Exit
;~
EndSwitch

WEnd

:huh2:

Any hints?

Not sure why the GDI+ stuff is causing a problem, but if all you need it for is to get the dimensions of the file, you could do it this way.

#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
#include <ScreenCapture.au3>
#include <Misc.au3>
#include <StaticConstants.au3>
#include <Array.au3>
Local $GUIimg_title, $GUIwidth, $GUIheight, $GUILeft, $GUITop

Local $filename = FileOpenDialog("Select image", @ScriptDir, "Image (*.jpg;*.bmp)", 3)

;~ _GDIPlus_Startup()

;~ Local $imagefromfile = _GDIPlus_ImageLoadFromFile($filename) ;Create an image object based on a file
;~ Local $GUIwidth = _GDIPlus_ImageGetWidth($imagefromfile)
;~ Local $GUIheight = _GDIPlus_ImageGetHeight($imagefromfile)

;~ _GDIPlus_Shutdown()

; Display image
$aDimensions = StringRegExp(_FileGetProperty($filename, "height"), "(d+)", 2)
$GUIheight = $aDimensions[0]
$aDimensions = StringRegExp(_FileGetProperty($filename, "width"), "(d+)", 2)
$GUIwidth = $aDimensions[0]
$hBitmap_GUI = GUICreate("", $GUIwidth, $GUIheight)
$hPic = GUICtrlCreatePic($filename, 0, 0, 0, 0)

I used the RegEx because the results on my computer returns ### pixels, where the ### is the dimension size and this will strip off anything not a number.

This works on Windows 7, XP does not have this information available, but does have the Dimensions property you could work with.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

It's because you do not dispose the image and is still in use. Try this:

#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
#Include <ScreenCapture.au3>
#Include <Misc.au3>
#include <StaticConstants.au3>

Local $GUIimg_title,$GUIwidth,$GUIheight,$GUILeft,$GUITop

Local $filename = FileOpenDialog("Select image", @ScriptDir, "Image (*.jpg;*.bmp)", 3)

_GDIPlus_Startup()

Local $imagefromfile = _GDIPlus_ImageLoadFromFile($filename) ;Create an image object based on a file
Local $GUIwidth = _GDIPlus_ImageGetWidth($imagefromfile)
Local $GUIheight = _GDIPlus_ImageGetHeight($imagefromfile)
_GDIPlus_ImageDispose($imagefromfile)
_GDIPlus_Shutdown()

; Display image
$hBitmap_GUI = GUICreate("", $GUIwidth, $GUIheight)
$hPic = GUICtrlCreatePic($filename, 0, 0, $GUIwidth, $GUIheight)

GUISetState()

      I'm building a tool to remotely monitor CPU usage on my server.
      I have a working tool but I have a few issues I'd like some help with.
      1. The app uses more system memory on a continual growth rate...  It eventually starts displaying strange artifacts and the background flashes between black and and white behind the GDI+ elements.  I determined this couldn't be left to run for any amount of time (greater than 15-20 minutes) - Very frustrating.
      I suspect it's because it keeps drawing new GDI+ elements to replace the previous cycle ... the $bar1 = "" is enough to remove the image and allow the new image to be drawn there, but I don't have a handle for the original GDI+ element to throw it away... Not sure where they go...
      I also suspect there could be a better way to do what I'm doing here, but from a problem solving perspective - this is what I came up with - I will accept suggestions for how better to accomplish the same / better or acceptable results  
      I will not however accept corrections on grammar, punctuation or commenting - I didn't comment this as I was going, I use the variables that make sense to me (or as they were when I lifted them from the scraps I found on the internet) and you can never be too careful with punctuation.
      2. I have a WMI query that is used to remotely pull the CPU data from the server - if I supply the wrong credentials the app crashes... I tried to make it show an error and go back to allow me to try again ... doesn't work. Any help with catching that error and preventing the crash would be super helpful. (works great if the credentials are correct; domain or local)

      Hello,
      I am making a program where the button is an image that "changes" when specific conditions are fullfilled. Problem is that these images have different dimensions and when a smaller picture is displayed over a bigger one both will be seen, therefore i would like the images to be hidden, invincible or, alternatively, deleted.
      I have tried using _GDIPlus_GraphicsClear() with no luck
      However that might just be me not using it right as im quite new to autoit
      Here is the code if you want to test run it:
      Thanks to everyone helping!

      This script used to work on an older version of AutoIT. Currently I am running AutoIT v3.3.14.5 and it's failing.

      AutoIt Windows Screenshooter
      Key Features:
      takes easily a screenshot from any visible window capture any region of the desktop incl. freehand capturing capture GUI controls and GUI menus separately capture a marked area every x seconds for a duration of y seconds create a GIF animation from saved frames (Vista or higher os required) capture to AVI file (without audio!) takes a screenshot from web sites (available only on Win7+ os and when Aero is enabled) put images to clipboard to paste to other applications easily color picker save image in different formats and also to PDF! add timestamp to saved images simple image editing options: greyscale, b&w, invert, rotate +-90° send image to printer and default email client preview of captured screens incl. zoom option multi monitor support display pixel color under mouse ruler basic image editor (paint, highlight, ellipse, rectangle, text and some graphic FX) watermark captured image no 3rd party tools or DLLs used - pure AutoIt! fully portable - no installation is needed multi language feature (Eng, Ger, Tur, Fra and Rus only) To do:
      capture content of scrollable window/control capture cascaded menus Due to DllCall("User32.dll", "int", "PrintWindow", "hwnd", $hWnd, "handle", $hMemDC, "int", 0) limitation some windows cannot be captured properly (GDI+, ProgDVB, etc.) but can take screenshots of hidden windows. One workaround is to use full screen capturing (F11/F12) or "Grab Screen" function! Or try double click with rmb on listview items (beta).

      Hello,
      I wrote a benchmark script to measure variable declarations
      to find out whether you should focus more on static or global variables
      #cs ---------------------------------------------------------------------------- AutoIt Version: 3.3.14.5 #ce ---------------------------------------------------------------------------- #Region Pre-Setting Local $iTally1 = 0 Local $iTally2 = 0 Local $iTally3 = 0 Local $iTally4 = 0 Local $iTally5 = 0 Local $iTally6 = 0 Local $iTally7 = 0 Global $GLOBALCONST1 = 1 Global $GLOBALCONST2 = 1 Global $GLOBALCONST3 = 1 Global $GLOBALCONST4 = 1 Global $GLOBALCONST5 = 1 #EndRegion Pre-Setting #Region Test Functions Func s1() Static $i = $GLOBALCONST1 Return $i EndFunc Func g2() Return $GLOBALCONST2 EndFunc Func g3() Static $i7 = "gsdgdfegbgbrwefw" Return $GLOBALCONST3 EndFunc Func g4() Static $i1 = 1 Static $i2 = "asd" Static $i3 = 234 Static $i4 = True Static $i5 = [0] Static $i6 = "hgsdg" Static $i7 = 1 Static $i8 = 1 Static $i9 = 1 Static $i0 = 1 Return $GLOBALCONST4 EndFunc Func g5() Local $i = $GLOBALCONST5 Return $i EndFunc Func g6() Local $i = 1 Return $i EndFunc Func g7() Return 1 EndFunc #EndRegion Test Functions #Region Benchmark Loop For $i = 0 To 15 Local $tDelta = TimerInit() Do $iTally1 += s1() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally2 += g2() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally3 += g3() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally4 += g4() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally5 += g5() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally6 += g6() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally7 += g7() Until TimerDiff($tDelta) >= 1000 Next #EndRegion Benchmark Loop ConsoleWrite(@CRLF&"Static1: "&$iTally1&" pkt"&@CRLF&"Global2: "&$iTally2&" pkt"&@CRLF&"Global3: "&$iTally3&" pkt"&@CRLF&"Global4: "&$iTally4&" pkt"&@CRLF&"Local5: "&$iTally5&" pkt"&@CRLF&"Local6: "&$iTally6&" pkt"&@CRLF&"Hardcode7:"&$iTally7&" pkt"&@CRLF) #cs Result Static1: 10291881 pkt global to static Global2: 13977324 pkt only global Global3: 9886169 pkt global and static Global4: 2933051 pkt global and many statics Local5: 9937314 pkt global to local Local6: 10306484 pkt only local Hardcode7: 14835319 pkt no variable #ce Result:
      100% no variable, hardcore value
      94% only global variable use
      69% only local variable use with hardcore value set
      69% only static variable use with global variable value set
      67% declaration of local variable with global variable value set
      66% only global variable use with one static variable beside
      20% only global variable use with ten static variables beside
      My thesis of the result:
      Be careful with declarations, whether local, global or static Note: in my test the global variable performance was better than the local one, but in practice the global one would lose performance due to multiple operations
       
      What is your best practice sharing data between multiple functions?
