Hello, I am using this GUI to test drag & drops: #include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#Include <GuiButton.au3>
Global $hGUI = GUICreate("ParentX",500,500,-1,-1,-1,-1)
Global $hInput = GUICtrlCreateLabel("",0,0,507,507,-1,16)
GUICtrlSetState(-1,88)
GUICtrlSetBkColor(-1,"-2")
GUISetState()
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
Exit
Case $GUI_EVENT_DROPPED
MsgBox(64, "Drag & Drop", '@GUI_DragFile = ' & @GUI_DragFile & @CRLF & '@GUI_DragId = ' & @GUI_DragId & @CRLF & '@GUI_DropId = ' & @GUI_DropId)
EndSwitch
WEndBut the MsgBox is not working Thanks in advance, TD
