Transparent GUI & PNG Controls

[Unc3nZureD]

I'd like to build my software of pictures. I've already made some PNGs with transparency, howevery I don't need the GUI background. So, let me show you where I'm at currently

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <StaticConstants.au3>
#include <WinAPI.au3>
#include "GUICtrlPic.au3"

Dim $GO = False
AdlibRegister("_Play", 100)

$Form1 = GUICreate("Updater Test", 899, 590)
$a0 = _GUICtrlPic_Create(@ScriptDir & "\uresbar.png", 64, 438, 769, 60)
$a1 = _GUICtrlPic_Create(@ScriptDir & "\uresbar.png", 64, 501, 769, 60)
$a2 = _GUICtrlPic_Create(@ScriptDir & "\telibar.png", 64, 438, 769, 60)
$a3 = _GUICtrlPic_Create(@ScriptDir & "\telibar.png", 64, 501, 769, 60)
$a4 = _GUICtrlPic_Create(@ScriptDir & "\háttér.png", 0, 0, 899, 590)
$a5 = _GUICtrlPic_Create(@ScriptDir & "\buttpassive.png", 329, 381, 241, 50)
GUISetState(@SW_SHOW)

For $i = 0 to 100
    _GuiCtrlSetProgress($a2, $i)
Next

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $a5
            MsgBox(0,"", "START")
    EndSwitch
WEnd

Func _Play()
    $ReadMouse = GUIGetCursorInfo()
    If IsArray($ReadMouse) = 1 Then
        Select
            Case $ReadMouse[4] = $a5 And $GO = False
                _GUICtrlPic_SetImage($a5, @ScriptDir & "\buttactive.png", 0)
                $GO = True
            Case $ReadMouse[4] <> $a5 And $GO = True
                _GUICtrlPic_SetImage($a5, @ScriptDir & "\buttpassive.png", 0)
                $GO = False
        EndSelect
    EndIf
EndFunc

Func _GuiCtrlSetProgress($idPic, $data)
    $aBitmap = _GUICtrlPic_LoadImage(@ScriptDir & "\telibar.png")
    $hBitmap = $aBitmap[0]

    $hBitmap = _GUICtrlPic_ScaleBitmap($hBitmap, 769 * $data / 100, 60, $aBitmap[1], $aBitmap[2])
    GUICtrlSendMsg($idPic, 0x0172, 0x0000, $hBitmap)
    GUICtrlSetState($idPic, $GUI_SHOW)

    Return True
EndFunc

This one works well, I just would like to remove the background of my main "GUICreate". Is it possible anyways?

Here's a pic what annoys me if it's still not clear

$WS_POPUP style of any use?

Look this:

'?do=embed' frameborder='0' data-embedContent>>

$WS_POPUP + $WS_EX_LAYERED + _WinAPI_UpdateLayeredWindow
