File(s) Drag & Drop

Send "Drag & Drop File(s)" Message

I was looking for this functionality before, and couldn't figure out the correct method for using the WM_DROPFILES message. Thankfully today I came across the thread ' and found working, but flawed, code for doing exactly this. Specifically, (his 'DoDragDrop' function).

I cleaned up the code, added error checking, Unicode & x64 support, and fixed the Global memory management issues. The result is down below.

Also, see ProgAndy's COM implementation of Drag&Drop: '

Another good reference, besides those in the thread above, is this article at CodeProject: 'How to Implement Drag and Drop Between Your Program and Explorer'

Examples of usage:

TeraCopy

_FileDragDrop(WinGetHandle("[REGEXPTITLE:TeraCopy.*]"),@ScriptFullPath&'|'&@AutoItExe)

Notepad++:

$hNPPlus=WinGetHandle("[CLASS:Notepad++]")
$aNPPPos=WinGetPos($hNPPlus)
;~ WinActivate($hNotePad)
$sProgramFiles=@ProgramFilesDir
If @AutoItX64 Then $sProgramFiles&=' (x86)'
$iRet=_FileDragDrop($hNPPlus,@ScriptFullPath&'|'&$sProgramFiles&"\AutoIt3\Include\Memory.au3",$aNPPPos[2]/2,$aNPPPos[3]/2)
ConsoleWrite("Return: "&$iRet&" @error="&@error&", @extended="&@extended&@CRLF)

Be sure to credit the original authors, or leave the headers intact, if you use the code :graduated:

*edit: for some friggin reason I can't post the code in the post - I get a 'You must enter a post' error message - wtf. Attaching it for now..

UPDATES:

2010-12-4 (yup, today!):

  • Fixed ANSI implementation
  • Changed Memory allocation type to 'Fixed' (thanks trancexx)
  • Added X, Y position parameters - actually needed for some programs (Notepad++ for example)

Both ways, KaFu. Maybe there's some formatting in the script that the forum doesn't recognize? *shrug*

Nice, that one goes straight to the snippet box, offers a good new way to automate applications :graduated:... Thanks m8!

Thanks. As far as I can recall, TeraCopy was the only program I needed this for a while back. I think there were other types of Drag-and-Drop messages I wanted to use also, but can't recall for what.

Oh, and for anyone that is curious - no, this doesn't seem to work for Explorer windows, but then that's more of a job for FileCopy().

It's nice.

Btw, is there any particular reason for allocating movable memory?

Fixed memory would result in shorter (safer) code.

trancexx,

For some odd reason I thought it needed a handle to a Global Memory object, but after some tests, it seems it works fine with a pointer instead. Thanks for the help. Updated the post with the new changes, plus ANSI fixes.
