Adding a help icon in WinForms form titlebar

Question

Some sister Windows applications have a question mark icon in the title bar. It is usually located on the right edge, next to the close button. How to do this in a C # WinForms application? I would like the solution to work in Windows XP.

Answer 1

Set the HelpButton property to True. You also need to set the MaximizeButton and MinimizeButton properties to False.
