Simulate Drag & Drop on Control

[DJ VenGenCe]

I am having problems simulating a drag and drop onto Control SysListView3 which is a list view. Basically Dragging and Dropping MP3s works, but when I use ControlSetText, etc, it does not.

If more info is needed, I'll be happpy to oblige.

I have also attached the AutoIT Window Info Summary.

Drag & Drop files here

AutoIT Window Info:

You might be able to drop files onto the control by sending it a message if you can find it's handle.

This function was written by motionman and a bit by me

expandcollapse popup

#include <WinAPI.au3>
#include <Memory.au3>
#include <Misc.au3>

Const $WM_DROPFILES = 0x233


Func DoDropFiles2($wnd, $Files)
;$wnd is the handle of the control we are dropping onto
;$Files is the list of files separated by "|"

 $tagStruct1 = "int offset;int px;int py;byte fNC;byte fWide"

;grab some memory
    $hGlobal = _MemGlobalAlloc(14 + StringLen($Files) + 2)
;DropFiles := GlobalLock(MemHandle)
;translates the memory handle to a pointer
    $pDropFiles = _MemGlobalLock($hGlobal)
;create the struct in this memory
    $DropFiles = DllStructCreate($tagStruct1 & ";char filelist[" & StringLen($Files) + 2 & "]", $pDropFiles)
    DllStructSetData($DropFiles, "offset", 14);14 = int+int+int+byte+byte
    $dummy = 0; done its job
    DllStructSetData($DropFiles, "px", 0);tried setting a point inside Notepad
    DllStructSetData($DropFiles, "py", 0);but it makes no difference
    DllStructSetData($DropFiles, "fwide", 0)
    DllStructSetData($DropFiles, "fNC", 0)
    DllStructSetData($DropFiles, "filelist", $Files)
;set the nulls in place of the separaters
    $Size = 0;
    $Files = StringSplit($Files, "|")
    For $I = 1 To $Files[0]

    ;// number of characters per string (as ANSI) plus one #0 terminator
    ;Inc(Size, Length(Files[I]) + 1);
    $Size += StringLen($Files[$I]) + 1
    DllStructSetData($DropFiles, "filelist", 0, $Size)
    Next
    ;ConsoleWrite(DllStructGetData($DropFiles, "filelist") & @CRLF)
;now add the extra null to terminate the list of strings
    DllStructSetData($DropFiles, "filelist", 0, $Size + 1)
    _MemGlobalUnlock($hGlobal)
    _WinAPI_PostMessage($wnd, $WM_DROPFILES, $hGlobal, 0);
;// ... and finally release the memory

    _MemGlobalFree($hGlobal)
EndFunc ;==>DoDropFiles2

But search for functions by Prog@ndy because after that function was written he wrote some very good code for drag-drop.
