Clearing image on desktop

[rliiack]

For example I use the _GDIPlus_GraphicsDrawImageRectRect function to draw an image on the desktop. Is it possible to erase or clear the image after drawing it?

Method 1

DllCall('shell32.dll', 'none', 'SHChangeNotify', 'long', 0x08000000, 'uint', 0, 'ptr', 0, 'ptr', 0)

Method 2

_SendMessage(_WinAPI_FindWindow('Progman', 'Program Manager'), 0x0111, 0x7103, 0)

Method 3

_WinAPI_ShowWindow(_WinAPI_FindWindow('Progman', 'Program Manager'), @SW_HIDE)
_WinAPI_ShowWindow(_WinAPI_FindWindow('Progman', 'Program Manager'), @SW_SHOW)

Thanks, they work perfectly.

[rliiack]

However, is there any way to update the screen without it flashing?

Not sure what does _WinAPI_SelectObject($hDC, $hOldFont) do. How come the Hello closes after I haven't pressed OK? I did a if statement, but it acts the same too.

_WinAPI_DeleteObject($hFont)
_WinAPI_ReleaseDC(0, $hDC)
_WinAPI_InvalidateRect($hWnd, $tRect, 1)
EndIf

This part is need to draw "Hello world!" only. I took it from the help file. Do not pay attention to it.

$tRECT = DllStructCreate($tagRect)
DllStructSetData($tRECT, 1, 5)
DllStructSetData($tRECT, 2, 5)
DllStructSetData($tRECT, 3, 250)
DllStructSetData($tRECT, 4, 50)

$hDC = _WinAPI_GetDC(0)
$hFont = _WinAPI_CreateFont(50, 0, 0, 0, 400, 0, 0, 0, $DEFAULT_CHARSET, $OUT_DEFAULT_PRECIS, $CLIP_DEFAULT_PRECIS, $DEFAULT_QUALITY, 0, 'Arial')
$hOldFont = _WinAPI_SelectObject($hDC, $hFont)
_WinAPI_SetTextColor($hDC, 0x0000FF)
_WinAPI_SetBkMode($hDC, $TRANSPARENT)
_WinAPI_DrawText($hDC, 'Hello world!', $tRect, $DT_CENTER)
_WinAPI_SelectObject($hDC, $hOldFont)
_WinAPI_DeleteObject($hFont)
_WinAPI_ReleaseDC(0, $hDC)

The next part will be update the whole Desktop.

$hWnd = ControlGetHandle(_WinAPI_FindWindow('Progman', 'Program Manager'), '', '[CLASS:SysListView32;INSTANCE:1]')
_WinAPI_InvalidateRect($hWnd, 0, 1)

But it will flicker, and so I reduced the update area to as needed (see $tRect).

$hWnd = ControlGetHandle(_WinAPI_FindWindow('Progman', 'Program Manager'), '', '[CLASS:SysListView32;INSTANCE:1]')
_WinAPI_InvalidateRect($hWnd, $tRect, 1)

This is exactly what does Windows when you, for example, move a windows on the Desktop. Updated only required area.

It looks nice but when I implement it, it gives me an error.

Ironically misrepresented that you do not need to draw on the Desktop, better to create your own window and "conjure" in it. Below is a simple example "Magnify x4". Here is something to think about, but on the whole idea should be clear. And no any flicker.
