I am trying to get an image showing through a edit box. I am only successful in making the edit box totally transparent
#include-once #include <GUIConstants.au3> #include <GDIPlus.au3> #include <WinAPISys.au3> #include <colorconstants.au3> ;WS_EX_TRANSPARENT $gui = GUICreate("", 1000, 800, -1, -1, -1 , $WS_EX_LAYERED) ; use layered to get _winapi_setlay... to work $pic = GUICtrlCreatePic("c:\Program Files (x86)\AutoIt3\Examples\GUI\Merlin.gif", 0,0,1000, 800) GUICtrlSetState(-1, $GUI_DISABLE) $edit = GUICtrlCreateEdit("First line" & @CRLF, 176, 32,200,600) GUICtrlSetBkColor(-1,$COLOR_YELLOW) _WinAPI_SetLayeredWindowAttributes($gui,$COLOR_YELLOW,199) ; 199 is alpha (transparency level) GUISetState(@SW_SHOW,$gui) While 1 $msg = GuiGetMsg() Select Case $msg = $GUI_EVENT_CLOSE ExitLoop Case Else EndSelect WEnd Exit Func Terminate() exit(0) EndFunc So I am making the edit box's background yellow then using the _WINAPI_SetLayeredWIndowAttributes command to make the yellow disappear (which it does), but the alpha level is supposed to give a bit of opaqueness to it, but its not, just making it totally transparent. The alpha level is in fact affecting the window itself and not the edit box. I only want the edit box to be partially transparent.
I am searching for a way to display a transparent image (or Icon) over an Button. And the image should always stay on top.
Here is what i have so far:
At script start the picture is over the button..but if you move the mouse over the button it overlaps the image.
And if i add $GUI_ONTOP to the picture, the transparency is gone
Maybe someone has an idea..
Thanks in advance!

I'm trying to script an ellipse drawing algorithm in AutoIT for learning purposes.
I use an edit control to "draw" the ellipse with characters.
The code i have works kinda good but i would like to see if others around here know a better algorithm to do it..
I would like to be able to give the x, y and width, height arguments to the function and not have to start at the middle point and draw the ellipse around it.
side note, the ellipse glitches when it has to be 2 pixels high too..
func ellipsePlotPoints ($xc,$yc, $x,$y) pixel ($xc + $x, $yc + $y) pixel ($xc - $x, $yc + $y) pixel ($xc + $x, $yc - $y) pixel ($xc - $x, $yc - $y) endfunc func ellipse($xc,$yc, $a,$b) local $a2 = $a * $a local $b2 = $b * $b local $twoa2 = 2 * $a2 local $twob2 = 2 * $b2 local $p local $x = 0 local $y = $b local $px = 0 local $py = $twoa2 * $y ; Plot the initial point in each quadrant. ellipsePlotPoints ($xc,$yc, $x,$y) ; Region 1 $p = int($b2 - ($a2 * $b) + (0.25 * $a2)) while ($px < $py) $x+=1 $px += $twob2 if ($p < 0) then $p += $b2 + $px else $y-=1 $py -= $twoa2 $p += $b2 + $px - $py endif ellipsePlotPoints ($xc,$yc, $x,$y) wend ; Region 2 $p = int ($b2 * ($x+0.5) * ($x+0.5) + $a2 * ($y-1) * ($y-1) - $a2 * $b2) while ($y > 0) $y-=1 $py -= $twoa2 if ($p > 0) then $p += $a2 - $py else $x+=1 $px += $twob2 $p += $a2 - $py + $px endif ellipsePlotPoints ($xc,$yc, $x,$y) wend endfunc
WinSetState ("[CLASS:OpusApp]", "", @SW_SHOWMAXIMIZED) and WinSetState ("[CLASS:OpusApp]", "", @SW_MAXIMIZE) don't maximize the window. Using WinSetState("[CLASS:OpusApp]","",@SW_RESTORE) allows me to maximize it about 15% of the time. I've tried using WinMove("[active]",0,0,@Desktopwidth,@Desktopheight), but that only makes it worse. I've also tried putting in a sleep and maximizing it again. Does anyone have a solution?
Here's my code:
The startup script is intentionally commented, because I'm not testing it right now. The other comment is just for debugging when I need it.
UPDATE: When I run two instances of the program, it works almost all the time, but if I copy the code inside the else statement twice it doesn't work at all (despite the fact that it's running the same code just in one program vs two). I also noticed that when I run two instances of it, about 50% of the time when it opens both the windows, it also hits the windows button and types the letter d into the search box. Neither of these actions are in my code. I'm not really sure what's going on.
I know many newbies search for this feature.
I decided to share this piece of code with everyone.
Basically its a "splash screen" that has a transparent image.
In a nutshell - Gui with a transparent gif.
