Adding help icon to WinForms form titlebar
c#, icons, winforms
Solution
Set the form's HelpButton property to True. You also need to have the MaximizeButton and MinimizeButton properties set to False.
Problem
Some Windows native applications have a question mark icon on the title bar. It's usually at the right edge, just near the close button. How can I do this in a C# WinForms application? I'd like a solution that works in Windows XP onward.
