#3255 assigned Bug

Drag & Drop not working when Windows DPI setting is above 100%

Reported by: antonis@… Owned by: Jon
Milestone: Component: AutoIt
Version: 3.3.14.0 Severity: None
Keywords: Cc:

Description

I've noticed that drag & drop in AutoIt GUI doesn't work when Windows DPI is set higher than the default 100%. I got a new monitor and I'm using it at 150% since the resolution is very high. When trying to drag & drop using scripts that I know work it just doesn't do anything. If I change the setting to 100% it works as normal.

Test code:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#NoTrayIcon

Opt("GUIOnEventMode", 1)

Global $MainGUI

GUICreation()

While 1

Sleep(1000)

WEnd

Func GUICreation()

$MainGUI = GUICreate("Test", 500, 100, Default, Default, "", $WS_EX_ACCEPTFILES)
$TestInput = GUICtrlCreateInput("", 80, 10, 348, 20)
GUICtrlSetState($TestInput, $GUI_DROPACCEPTED)
$Exit = GUICtrlCreateButton("Exit", 220, 40, 60, 25)
GUICtrlSetOnEvent($Exit, "Quit")
GUISetState(@SW_SHOW)

EndFunc ;==>GUICreation

Func Quit()

GUIDelete($MainGUI)
Exit

EndFunc ;==>Quit

Try this code with your monitor set to 100% and try dragging & dropping a file in the Input, it's location should populate the Input, then set it to something higher like 125% or 150% and try dragging & dropping a file again to reproduce the issue.

The setting is in Display Settings, under "Customize your display" and says "Change the size of text, apps, and other items"

I reproduce your pb uder Window10 RS3
I don't know how to correct as it is working under Windows 7
Jon certainly can understand and fix it (change by WIndows DPI handling is certainly the pb)

Finaly I submit a fix to Jon going around the Fact that the Windows API DragQueryPoint() is working differently Under Windows 10
