nsis drag and drop for nsdialogs

Question

i want to drag and drop the window by image , i mean : you hold the mouse1 on main image or on a little label to get drag and drop on the window(left right , up down ) .

i have already tried code like this:

System::Call "user32::GetCursorPos(lp$MoveSize)"
System::Call "user32::ScreenToClient(i$HWNDPARENT, lp$MoveSize)"
System::Call "user32::SendMessage(i$HWNDPARENT, i$WM_SYSCOMMAND, i$SIZE, i0)"

but these functions is not talking to me. seem to works with old file "nsWindows.nsh"

SendMessage $HWNDPARENT ${WM_NCLBUTTONDOWN} ${HTCAPTION} $0
