File drag and drop

6 posts in this topic

i have an edit control, and i'd like to be able to drag a file to it and drop it, after that a function takes the file name and path (without adding to/replacing the content of the edit control) and passes it to another program and reads the output to a variable. but according to the documentation i can't do this, it will always be appended(maybe replaced? i don't quite understand "The edit/input control will be set with the filename.") to the text already in the control

skyboy,

This should help you for the first part:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#Include <GuiEdit.au3>

$hGUI = GUICreate("Dropped Files", 500, 400, Default, Default, Default, $WS_EX_ACCEPTFILES)

$hEdit = GUICtrlCreateEdit("", 10, 10, 480, 380)
GUICtrlSetState(-1, $GUI_DROPACCEPTED)
$hEdit_Handle = GUICtrlGetHandle(-1)

GUISetState(@SW_SHOW)

GUICtrlSetData($hEdit, "This is existing text")

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $GUI_EVENT_DROPPED
            $file = @GUI_DragFile
            ConsoleWrite($file & @CRLF)
            Sleep(2000) ; This only here you you can see the drop has taken place
            _GUICtrlEdit_ReplaceSel($hEdit_Handle, "")

    EndSwitch
WEnd

Melba, while your solution would work, it's something i wanted to avoid, and i will look for that inter-script communication, though for an unrelated project (this is going to use Run to read the output of a console application). and your solution was what i was looking for, martin though with a slight modification; returning false at the end of WM_DROPFILES_FUNC prevents the file name from showing up in the edit control
