+// Description:
+// Tests semi-transparent window owning control with background display properly when having a child window
+// owning semi-transparent control.
+// Creats a window application with two semi-transparent window owning parent controls both with background. 
+// A semi-transparent child window owning control is created for each parent control. One of the child control
+// enables transparent property properly, the other does not. 
+// The child control which enables transparent property properly should not cause the background of parent control
+// to redraw thus in all circumstance its parent control background drawing count should be less than the one doesn't
+// enable transparent control with provided function.
+//
