How to Resize GDI+ Layed Window?

Lakes · November 4, 2011

How to resize a transparent (layered window) when there`s no border or sizing controls to click on? (You can`t use WM_SIZE).

I tried to do it with a slider control, but I can`t get it to work.

; ============ React to slider movement ========================
Func WM_H_Slider($hWnd, $iMsg, $wParam, $lParam)
    #forceref $hWnd, $iMsg, $wParam
    If $lParam = $Trans_Handle Then
        $TransValue = GUICtrlRead($Trans)
  DllStructSetData($tBlend, "Alpha", $TransValue)         ; Set Alpha (Transparency) Level
  DllStructSetData($tBlend, "Format", 1)
        ToolTip($TransValue)
    EndIf
;=============== ; Size Window? ==================
    If $lParam = $Size_Handle Then
        $SizeValue = GUICtrlRead($Size)
  DllStructSetData($tSize, "X", $iX - $SizeValue)
  DllStructSetData($tSize, "Y", $iY - $SizeValue)               
  
;Update layered Window
$gdibitmap = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hbitmap)
    _WinAPI_SelectObject($dc, $gdibitmap)
    _WinAPI_UpdateLayeredWindow($hGUI, $ScreenDc, 0, $pSize, $dc, $pSource, 0, $pBlend, 2)
_WinAPI_DeleteObject($gdibitmap)
_WinAPI_RedrawWindow($hGUI)
        ToolTip($SizeValue)
    EndIf
Return "GUI_RUNDEFMSG"
EndFunc

Fantastic!!

No idea what that "DllCall($ghGDIPDll" call does, but it works!!

Thank you very much for replying so quickly!
