Or if you need _only files_ dragging

1. Call m_wndList.DragAcceptFiles(TRUE);

2. Add ON_WM_DROPFILES() to message map

3. add member like

void CYourListCtrl::OnDropFiles(HDROP hDropInfo)

{

UINT nFiles = ::DragQueryFile(hDropInfo, (UINT)-1, NULL, 0);

for (UINT iFile = 0; iFile < nFiles; iFile++)

{

TCHAR szFileName[_MAX_PATH];

::DragQueryFile(hDropInfo, iFile, szFileName, _MAX_PATH);

Process(szFileName);

}

::DragFinish(hDropInfo);

}

you can use CListView instead of CListCtrl and override members of CView:

DROPEFFECT CView::OnDragEnter(COleDataObject* /*pDataObject*/,

DWORD /*dwKeyState*/, CPoint /*point*/)

{

return 0; // DROPEFFECT_NONE

}

DROPEFFECT CView::OnDragOver(COleDataObject* /*pDataObject*/,

DWORD /*dwKeyState*/, CPoint /*point*/)

{

return 0; // DROPEFFECT_NONE

}

BOOL CView::OnDrop(COleDataObject* /*pDataObject*/,

DROPEFFECT /*dropEffect*/, CPoint /*point*/)

{

return FALSE;

}
