use more than one flag by adding the values, but you cannot use contradictory values (such 
as both OFN_FILEMUSTEXIST and OFN_CREATEPROMPT) that have opposite functions.<br>

<p>The Insert After Flags are used by SetWindowPos to determine the window's position in

These constants set the Z-order of the window to a certain value.<br>

it how to move the window. Most of them either tell the function not to move the window in 
some way or affect the redrawing of the window. You can use as many of these as you want 
by Or-ing them together, as long as you do not try to use two opposite flags (like 
SWP_HIDEWINDOW and SWP_SHOWWINDOW). </p>
