Open file via Drag'n'Drop on GUI

13 posts in this topic

When I move a file from Explorer on the gui via Drag'n'Drop the file should be opened automaticly.

For expample, I move a video file on the gui and the gui opens the file with vlc.

Is this possible with autoit?

Sounds good.

Can you tell me some key words I have to search for to realize it, that would help. ;-)

"drag + drop" yielded a number of results for me on the forum search.

blumi,

Search the forum for $WS_EX_ACCEPTFILES & $GUI_DROPACCEPTED - they are the styles you need to apply to your GUI and the relevant controls - and @GUI_DragFile - which will hold the filename. Then you can look to Run or ShellExecute to execute the file. :)

Okay, found some nice code.

Drag & Drop the file on the input field on the gui it works fine.

Did some tests without the input field but didn't work.

How to handle a gui without an input field where I can drag & drop the file on it?

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


Opt("GUIOnEventMode", 1)

GUICreate("Test GUI", 300, 100, -1, -1, -1, $WS_EX_ACCEPTFILES)
GUISetOnEvent($GUI_EVENT_DROPPED, "On_Drop_InFilename")
GUISetOnEvent($GUI_EVENT_CLOSE, '_exit')

GUICtrlCreateInput('', 28, 20, 240, 20)
GUICtrlSetState(-1, $GUI_DROPACCEPTED)

GUISetState(@SW_SHOW)

Func On_Drop_InFilename()
    GUICtrlSetData(@GUI_DropId, @GUI_DragFile)
        MsgBox(0, "test", "file: " & @GUI_DragFile)
EndFunc   ;==>On_Drop_InFilename

Func _exit()
    Exit 1
EndFunc   ;==>_exit



Do

    Sleep(10)

Until 0

That's a bit more complicated, as you'll have to deal with window messages directly. You'll want to search for the WM_DROPFILES message and the DragQueryFile / DragFinish functions.

blumi,

Here is some code to do what you want - credit goes to ProgAndy who showed me how to do it: ;)

#include <Array.au3>
#include <GUIConstantsEx.au3>

Global $gaDropFiles[1], $iDropItem = -1
Global $WM_DROPFILES = 0x233

GUICreate("DropIt", 241, 312, @DesktopWidth / 2 - 160, @DesktopHeight / 2 - 45, -1, 0x00000018); WS_EX_ACCEPTFILES
$FILES_DROPPED = GUICtrlCreateDummy()
GUISetState()
GUIRegisterMsg($WM_DROPFILES, 'WM_DROPFILES_FUNC')


While True
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case $FILES_DROPPED
            $aFiles = $gaDropFiles
            _ArrayDisplay($aFiles)
    EndSwitch
WEnd

Func WM_DROPFILES_FUNC($hWnd, $msgID, $wParam, $lParam)
    Local $nSize, $pFileName
    Local $nAmt = DllCall('shell32.dll', 'int', 'DragQueryFileW', 'hwnd', $wParam, 'int', 0xFFFFFFFF, 'ptr', 0, 'int', 0)
    ReDim $gaDropFiles[$nAmt[0]]
    For $i = 0 To $nAmt[0] - 1
        $nSize = DllCall('shell32.dll', 'int', 'DragQueryFileW', 'hwnd', $wParam, 'int', $i, 'ptr', 0, 'int', 0)
        $nSize = $nSize[0] + 1
        $pFileName = DllStructCreate('wchar[' & $nSize & ']')
        DllCall('shell32.dll', 'int', 'DragQueryFileW', 'hwnd', $wParam, 'int', $i, 'ptr', DllStructGetPtr($pFileName), 'int', $nSize)
        $gaDropFiles[$i] = DllStructGetData($pFileName, 1)
        $pFileName = 0
    Next
    GUICtrlSendToDummy($FILES_DROPPED, $nAmt[0])

blumi,

If you are not doing anything else with the gui it can be this simple...

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

Opt("GUIOnEventMode", 1)

GUICreate("Test GUI", 300, 100, -1, -1, -1, $WS_EX_ACCEPTFILES)
GUISetOnEvent($GUI_EVENT_DROPPED, "On_Drop_InFilename")
GUISetOnEvent($GUI_EVENT_CLOSE, '_exit')

GUICtrlCreatelabel('',0, 0, 300, 100)
GUICtrlSetState(-1, $GUI_DROPACCEPTED)

GUISetState(@SW_SHOW)

Func On_Drop_InFilename()
    GUICtrlSetData(@GUI_DropId, @GUI_DragFile)
        MsgBox(0, "test", "file: " & @GUI_DragFile)
EndFunc   ;==>On_Drop_InFilename

Func _exit()
    Exit 1
EndFunc   ;==>_exit

Do
    Sleep(10)
Until 0

Is it possible to do the same with  GUIOnEventMode?

Yes, just use GuiCtrlSetOnevent and GuiSetOnEvent instead  or GuiGetMsg. As a Univerlisat you should know what must be done to get it working in OnEventMode.

Great, thanx AutoBert

I didnt notice that  $FILES_DROPPED becomes a control there, so, I can use  GuiCtrlSetOnevent

$FILES_DROPPED = GUICtrlCreateDummy()
