// Modify the CMainFrame class....

// 1) Allow your application to accept dropped files by calling the
// following from your CMainFrame's OnCreate() message handler:

	// allow files to be dropped on main window or any child window
	DragAcceptFiles();

// 2) Add a WM_DROPFILES message handler to your CMainFrame class:

void CMainFrame::OnDropFiles(HDROP hDropInfo) 
{
	// get filename stored in hDropInfo and use app to open it
	TCHAR szFileName[_MAX_PATH];
	::DragQueryFile(hDropInfo, 0, szFileName, _MAX_PATH);
	::DragFinish(hDropInfo);
	AfxGetApp()->OpenDocumentFile(szFileName);
	
	CMDIFrameWnd::OnDropFiles(hDropInfo);
}
