I drew a polygon as you see in this figure with
PolyPolygon( ::oCiclo:GetDC(), aVertex )I had previously used gdiplus (transparent)
Now to draw another figure I have to delete the previously created figure
how can i do it?
what are the correct functions or commands?
another problem is that when I move a dialog over it or move the dialog where the polygon is drawn it gets deleted, as you can see here

if there is someone who can help me I am also willing to pay
