but my code deletes lines through one, where mistake? how to do it right?

2. i have simple flat form, without border and title, how i can simple draw an rectangle on a edge of a window with my color (i try LineTo, but is not very good way, i think)

4. how to convert twips to pixels and vice versa (eg. i get window rect with GetWindowRect and i trying to draw line with LineTo api-call from left-upper corner to right-upper corner, but from the right line goes out of window edge)
