From my dialog based application ,I invoke another 2 dialog windows .
1.First Dialog is modeless and invoked by thread .This dialog covers whole desktop area .
2.Second is a modal dialog and set as always top using follwoing function..and of 200x160 dimension.

SetWindowPos(&wndTopMost , 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

But , now also when I click on First dialog, Second Dialog is not visible at the top.
It's hidden beneath the first one.

How can I make this second dialog always visible at the top.. in this case.?

Thanks in Advance.~
