How to move the parent window in Child window?

Currently, I use:

::SendMessage(GetParent(),WM_NCLBUTTONDOWN,HTCAPTION,0);


to put the parent window in moving and sizing modal, but this has some side effects. so i'm looking for another way to let the parent go into the moving and sizing modal.

Answer

See WM_SYSCOMMAND. Pass SC_MOVE as the wParam value and 0 or -1 as the lParam value.
