App staying behind taskbar when starting in fullscreen [closed]

Answer 1

try:

Form.Left := 0; // set the x
Form.Top := 0; // set the y
Form.Width := Screen.Width; // width of the form
Form.Height := Screen.Height; // height of the form
// and
Form.FormStyle := fsStayOnTop; // taskbar is always on top as well, setting the Style property to always on top will allow the form to cover the taskbar

if you would like to hide the caption then set the borderstyle to bsnone
