How to make some text on screen wuthout bg? or set bg to invisible

[Realm]

Did you try the help file example?

I took this code from the example provided with _WinAPI_DrawText

expandcollapse popup

#include <WinAPI.au3>
#include <WindowsConstants.au3>
#include <FontConstants.au3>

Global $tRECT, $hFont, $hOldFont, $hDC

HotKeySet("{ESC}", "_Exit")

$tRECT = DllStructCreate($tagRect)
DllStructSetData($tRECT, "Left", 5)
DllStructSetData($tRECT, "Top", 5)
DllStructSetData($tRECT, "Right", 250)
DllStructSetData($tRECT, "Bottom", 50)

$hDC = _WinAPI_GetDC(0)
$hFont = _WinAPI_CreateFont(50, 0, 0, 0, 400, False, False, False, $DEFAULT_CHARSET, _
 $OUT_DEFAULT_PRECIS, $CLIP_DEFAULT_PRECIS, $DEFAULT_QUALITY, 0, 'Arial')
$hOldFont = _WinAPI_SelectObject($hDC, $hFont)

_WinAPI_SetTextColor($hDC, 0x0000FF)
_WinAPI_SetBkColor($hDC, 0x000000)
; comment next line to get black background instead of transparent one
_WinAPI_SetBkMode($hDC, $TRANSPARENT)

While 1
 _WinAPI_DrawText($hDC, "Hello world!", $tRECT, $DT_CENTER)
 Sleep(100)
WEnd

Func _Exit()
 _WinAPI_SelectObject($hDC, $hOldFont)
 _WinAPI_DeleteObject($hFont)
 _WinAPI_ReleaseDC(0, $hDC)
 _WinAPI_InvalidateRect(0, 0)
 $tRECT = 0
 Exit
EndFunc ;==>_Exit

Edit: You don't even need a GUI or background available with this script, if you want to hide a GUI when making your text on screen visible, you could set a command to minimize your GUI

here's a script that i did a while ago using one of Larry's ideas i believe, just shows a binary clock in the corner of the window, no background...
