Hello Ahmet Hoso,
This is also the standard behavior. You can not see the help button because it is located on the title bar. With FormBorderStyle
set to None, the title bar does not appear and hence the button. If you want to see it you must set the FormBorderStyle
to something other than None - SizableToolWindow
Please do not hesitate to write back if you have other questions.
