How do I display a png image in a specific x / y location without a GUI background to it?

Hi,

There are plenty of examples in the forum, search for these keywords "layered png".

    _WinAPI_DeleteDC($hMemDC)
EndFunc ;==>_GUICreate_Alpha

Is there a way to make $GUI = _GUICreate_Alpha("Look at the shiny", $pngSrc) - not show up in the taskbar? Also is it possible to have this always on top of windows? I tried: GUICtrlSetState(1, $GUI_ONTOP)

Sure, add TOPMOST and TOOLWINDOW exstyles.

GUICtrlSetState, like its name is made for GUI controls, not the GUI itself.

Do i add that to the Func _GUICreate_Alpha?

[FireFox]

GUI exstyles. Take a look at the GUICreate function in the helpfile to understand what I mean.

Br, FireFox.

Oh nm,     $hGUI = GUICreate($sTitle, $width, $height, $iX, $iY, $WS_POPUP, $WS_EX_LAYERED)

[Kore]

Thx got it working  BitOR($WS_EX_LAYERED, $WS_EX_TOPMOST)

[FireFox]

and ... $WS_EX_TOOLWINDOW
